The structural framing system (10) of the current invention with the unique cross sectional shape of its elongated members lends itself to manufacture from pultruded fiberglass material in a preferred embodiment. The present invention when manufactured in its preferred embodiment provides superior corrosion, fire and weather resistance while also providing a structural framing system which is light enough to be easily transportable.

Description

STRUCTURAL FRAMING SYSTEM AND METHOD OF ASSEMBLY

BACKGROUND OF THE INVENTION

The present invention relates in general to structural framing systems and pertains, more particularly, to a pultruded fiberglass, lightweight, and easily assembled frame for a house, shed or storage area which also provides superior strength, especially for climates which expose the structure to high winds.

Pultrusion allows fiberglass structural components to be manufactured in lengths which allow their superior strength characteristics to be utilized in the form of structural building components . The pultrusion process, although not the same, can be likened to an ordinary extrusion process in which fiberglass fibers are interlaced with a resin which is cured by the application of heat. The process is thoroughly described in U.S. Patent #3556888, Pultrusion Machine and Method, issued to Goldsworthy on January 19, 1971. It is important to note that the art of the present invention is not drawn to the pultrusion process itself, but to the unique shape, form, interconnection, application and method of use of the structural products described herein which are especially adapted to formation by ultrusion methods. With conventional structural framing systems, a tradeoff often exists between the weight of the structural materials, the ease of assembly of the structural materials, the skill level of the construction personnel required for assembly, the insulation properties of the structural materials, the material weathering and corrosion resistance characteristics, the material fire resistance, and the strength of the final structural assembly. For example, structural materials manufactured of steel generally provide a strong and fire resistant structural assembly but present weight concerns which inhibit material transporting, are difficult to assemble, are corrosion and weathering sensitive, are poor thermal insulators and often require many skilled construction personnel for assembly. Wood structural framing systems generally provide low weight, ease of assembly, and good insulation properties, but are often moderate to poor in their weathering, strength, and fire resistant characteristics and often require specialty assembly tools and skilled construction personnel. The art of the present invention provides for excellent material weight properties and ease of assembly with only a few ordinary tools and non-skilled construction personnel. The art of the present invention further provides for exceptional insulation properties, outstanding weathering characteristics, good fire resistance, and a final structural strength which is commensurate with many steel structures . All of the aforesaid advantages are available when the structural components of the present art, with the unique shapes, order of assembly, and means of connection described herein, are formed via the process of fiberglass pultrusion in a preferred embodiment. Accordingly, it is an object of the present invention to provide a structural framing system and method of assembly which is easily assembled, light in weight, energy efficient, fire resistant, weather and corrosion resistant, and structurally strong . Another object of the present invention is to provide a structural framing system and method of assembly which provides all of the aforementioned characteristics in a cost effective manner . A further object of the present invention is to provide a structural framing system and method of assembly which is capable of being assembled with a limited number of ordinary tools and non-skilled construction personnel. A still further object of the present invention is to provide a structural framing system having components which are readily manufactured from pultruded fiberglass.

SUMMARY OF THE INVENTION

To accomplish the foregoing and other objects of this invention, there is provided in a preferred embodiment a structural framing system having a plurality of pultruded fiberglass sill plates arranged in a substantially rectangular form; said rectangular form having an internal and external portion. There is further provided, four or more pultruded fiberglass outside corner posts, which are mounted substantially perpendicular to and attached to said sill plates, a plurality of pultruded fiberglass outside studs which are also mounted substantially perpendicular to the sill plates, one or more pultruded fiberglass eave headers (with inside attachment clips) across and on the top of the plurality of outside studs, one or more pultruded fiberglass gable headers (with inside attachment clips) , again across and on the top of the plurality of outside studs but located in a substantially 90° spatial relation with said eave headers, a ridge beam attached between the two opposing sides of the substantially rectangular form containing the gable headers, one or more column studs for support of said ridge beam, a plurality of pultruded rafters placed and attached between the ridge beam and the eave headers, a plurality of pultruded fiberglass inside studs which mate and attach to the outside studs within the substantially rectangular form, and a plurality of pultruded fiberglass window and door channels for those openings where a window or door would be desired. An alternative embodiment would replace the pultruded rafters and ridge beam with a plurality of trusses formed in a conventional manner, preferably from pultruded fiberglass material. Often the aforementioned sill plates are placed and secured onto a concrete footing. In a preferred embodiment, each sill plate is comprised of a pultruded and substantially "U" shaped channel cross section having an extension plate extending from the bottommost portion of the "U" on the internal side. Each extension plate is perpendicular to the walls of the "U" . An alternative embodiment of the sill plate would be comprised of the substantially "U" shaped channel only and would be used primarily for conventional foundations. The aforesaid outside corner posts are substantially rectangular and hollow in cross section with extension ears on each portion of the cross section which abuts the external portion of the substantially rectangular sill plate form. In a preferred embodiment, the outside corner post has a concave cross section portion which is located on a corner nearest the internal portion of the rectangular cross section and substantially opposite the corner of the portion of the cross section which is located near the external portion of the rectangular sill plate form. In a preferred embodiment, both the extension ears and the concave portion run the entire length of the outside corner post. The aforementioned outside studs are capable of being cut to various lengths. In a preferred embodiment, each outside stud is pultruded as a one piece substantially rectangular and hollow cross section on a plate extending beyond the width of the rectangular cross section. An alternative description would describe the outside stud as a substantially rectangular and hollow cross section having coplaner and substantially flat ears on that portion of the outside stud which is located near the external portion of the substantially rectangular sill plate form. Operating in conjunction with the outside studs are a plurality of inside studs. Each inside stud has the substantially same cross section as the outside stud with a lengthwise slot located between said flat ears and through a wall of said rectangular cross section. This slot allows for convenient runs and placement of utility wires, pipes, etc within the hollow portion of the inside stud. The inside stud is placed such that it mates and attaches lengthwise with the outside stud and has its flat ears opposite and away from said outside stud and on the internal side of the substantially rectangular sill plate form. Each eave and gable header is mounted parallel with and opposite the sill plate on a topmost portion of the outside studs. Securing of each eave or gable header is achieved via the use of an inside attachment clip which holds the header to the outside and inside stud combination. The combination of the inside clip and the header forms a header channel for utility runs. A channel cover, typically vinyl, is used for enclosure and covering of said channel if no other covering material such as drywall is placed thereover. Upon the installation of the eave headers and gable l headers the ridge beam is placed and attached between the two

2 opposing sides of the substantially rectangular form

3 containing the gable headers. The ridge beam may take one

4 of two forms. In an alternative embodiment, the ridge beam

5 comprises two fastener joined pultruded sections, between

6 which is sandwiched a flitch plate, preferably of steel, to 7maintain the necessary stiffness for a given span. In a 8 preferred embodiment, the ridge beam is pultruded as one 9 piece. The ridge beam has a ridge beam cover, preferably of 0 vinyl, which may be placed onto its interior exposed portion 1 if not covered by a material such as drywall or other 2 wallboard. 3 The ridge beam is supported by column studs or steel 4 columns at each end and at any other point where support is 5 required. In an alternative embodiment, steel columns are 6 used to support the ends of the ridge beam. In a preferred 7 embodiment, column studs are used to support said ridge beam. 8 Each column stud comprises a cross section substantially 9 similar to the outside studs except that the wall thickness 0 of said substantially rectangular cross section is 1 substantially thicker than the outside stud. When installed, 2 the column stud would replace and function as a typical 3 outside stud. 4 Upon installation of the ridge beam, rafters are placed 5 and attached between the ridge beam and the eave headers. 6 In a preferred embodiment, the rafters are pultruded and 7placed and separated by 24 inches, center to center, but may 8 be separated by any width required by the application. Each 9 rafter has an attaching rafter clip which is able to sandwich 0 and hold roofing panels and/or insulation material between 1 the clip and the main body section of the rafter. 2 Onto and parallel with each gable header is placed and fastened an end rafter. A rafter clip is placed onto each end rafter in order to sandwich and hold roofing panels and/or insulation material between the clip and the main body section of the rafter. An alternative embodiment places trusses, in lieu of the rafter and ridge beam combination, across the eave headers and secures each truss with a truss clip. Each truss is formed in a conventional manner, preferably of pultruded fiberglass members of substantially rectangular cross section

In order to provide structural mounting for windows and doors, a plurality of substantially *C" shaped window and door channels are mounted vertically and/or horizontally where necessary. These channels function much as conventional framing lumber with the exception that they offer all of the advantages of pultruded fiberglass. Although the preferred embodiments of the structural framing system components described herein would utilize a pultruded fiberglass material, the structural framing system of the present art may be manufactured of a variety of materials, including but not limited to wood, plastic, steel, aluminum, or other composite materials. The preferred and alternative embodiments described herein may also be manufactured in different sizes and colors.

All of the aforementioned structural components are fastened together in their respective locations with the use of conventional fasteners such as sheet metal screws, machine screws, nuts, and concrete anchor bolts, but may also be fastened using other types fasteners such as pins, studs or clamps or with the use of specialty adhesives. In a preferred embodiment, the fasteners are comprised of #10 sheet metal screws except for fastening of the column studs, ridge beam, flitch plate and associated beam, end rafters, and roof rafters which use ^-20 machine screws for fastening.

DETAILED DESCRIPTION Referring now to the drawings there is shown a preferred embodiment in FIGS. 1, 6-16, 18-25, & 27-31 of the structural framing system and the individual components of the invention, with FIGS. 6, 7, 15, 32 & 33 having some alternative components. Alternative embodiments of the structural column stud, sill plate and ridge beam are shown in FIGS. 2-5, 17, 26 respectively. An alternative embodiment showing the use of trusses is shown in FIG. 32. All of the structural components described hereafter, except for those noted, are elongated members whose cross section is substantially constant throughout the members elongation, thereby requiring description of the cross section only. The drawings show the structural framing system 10 affixed to a concrete footing 12. Preferred embodiments would not require a concrete footing 12, although one may be used for added structural integrity. The drawings also show a plurality of sill plates 14 arranged in a substantially rectangular form 20. The substantially rectangular form 20 defines an internal portion 22 and an external portion 24. In a preferred embodiment, the sill plate 14 is manufactured of pultruded fiberglass with a cross section of "U" shaped channel 18 and an integral extension plate 16 extending from the lowest portion of the "U" shape 18. The integral extension plate 16 provides additional support for said sill plate 14 , especially when a concrete footing 12 is not used. Alternative embodiments of the sill plate 14 do not contain the extension plate 16 and are primarily for applications which have a concrete footing 12. Into the sill plates 14 "U" shaped channel 18, at the corners of the substantially rectangular form 20, is attached and 1 mounted four or more outside corner posts 26 which are positioned

2 substantially perpendicular to and attached to said sill plates

314. In a preferred embodiment, the outside corner posts 26 are

4 formed from pultruded fiberglass with a substantially rectangular

5 and hollow cross section 27 with extension ears 28 on each

6 portion of the cross section which abuts the external portion 24

7 of the substantially rectangular 20 sill plate 14 form. A

8 preferred embodiment of the outside corner post also has a

9 concave cross section portion 30 which is located on a corner 10 nearest the internal portion 22 of the rectangular cross section 1127 and substantially opposite the corner of the portion of the

12 cross section 27 which is located near the external portion 24

13 of the rectangular sill plate form 20. In a preferred

14 embodiment , both the extension ears 28 and the concave portion

1530 run the entire length of the outside corner post 26.

16 Further attached and mounted onto the sill plates 14 is a

17 plurality of outside studs 32 which are also placed within and

18 substantially perpendicular to the sill plates 14 nearest the

19 external portion 24. In a preferred embodiment, the outside

20 studs 32 are formed from pultruded fiberglass and separated by 2124 inches, center to center, but may be separated by any width

22 required by the application. The aforementioned outside studs

2332 and the outside corner posts 26 are capable of being cut to

24 various lengths in order to accommodate the height and contour

25 of the structure 10 desired. In a preferred embodiment, each

26 outside stud 32 is formed as a one piece substantially 27 rectangular and hollow cross section 34 having coplaner and

28 substantially flat ears 36 on that portion of the outside stud

29 which is located near the external portion 24 of the

30 substantially rectangular sill plate form 20 when placed.

31 Operating in conjunction with the outside studs 32 are a

32 plurality of inside studs 38. Each inside stud 38 has

33 substantially the same cross section as the outside stud 32

34 except that the inside stud 38 has a lengthwise slot 40 located

35 between said flat ears 36 and through a wall of said rectangular

36 cross section 34. Hereafter for claim purposes, the cross

37 sectional description of the inside stud 38 shall be described 1 as a second rectangular and hollow cross section in combination

2 with a second coplaner and substantially flat ear. The slot 40

3 in the inside stud 38 allows for convenient runs and placement

4 of utility wires and pipes within the hollow portion of the

5 inside stud 38. The inside stud 38 is placed, within the sill

6 plate 14 and attached, and assembled such that it mates

7 lengthwise with the outside stud and has its flat ears opposite

8 and away from said outside stud 32 on the internal portion 22 of

9 the substantially rectangular sill plate form 20. The inside

10 stud 38 is also attached and mounted in a position which is

11 substantially perpendicular to the sill plates 14. Again, in a

12 preferred embodiment, each inside stud 32 is formed as a single

13 stud from pultruded fiberglass.

14 Upon placement of the outside studs 32, outside corner posts

1526, and the inside studs 38, the structural framing system 10 is

16 capable of accepting an attachment of two or more eave headers

1742 onto those portions of said studs 38, 32 and posts 26 opposite

18 the sill plate 14. The eave header 42 cross section is formed

19 from a first eave plate 44 and a second eave plate 46 which are

20 positioned between 90 and 135 degrees relative to each other.

21 Within the portion having said angle between 90 and 135 degrees

22 is placed an eave plate support section 48. The eave plate

23 support section 48 forms a support web between the aforesaid

24 plates 44, 46 and thereby reinforces the strength of the header

2542. Although the support section 48 may take the form of any

26 shape which helps to support the aforesaid plates 44, 46, in a

27 preferred embodiment, the section 48 forms a substantially right

28 angle. Again, in a preferred embodiment, each eave header 42 is

29 formed as a single header from pultruded fiberglass.

30 Furthermore, in a preferred embodiment, the eave headers 42 are

31 typically used in pairs and placed on two opposing sides of the

32 substantially rectangular form 20 in order to form the eave base

33 for the structural framing system 10.

34 Securing of each eave header 42 is achieved via the use of

35 an inside attachment clip 54 which holds the header to the

36 outside 32 and inside 38 stud combination via attachment to the

37 eave plate support section 48. The combination of the inside 1 clip 54 and the header 42 forms an eave header channel 50 for

2 utility runs. A channel cover, typically vinyl, is used for

3 enclosure and covering of said channel 50.

4 The inside attachment clip 54 cross section is typically

5 formed from a clip "U" shaped channel 56 having an attachment lip

658 and a contacting ear 60 formed integrally with said channel

756. The attachment lip 58 extends above the open end of the "U"

8 shaped channel 56 and is generally parallel with and in-line with

9 a leg of the topmost portion of the "U" of the "U" shaped channel

1056. In a preferred embodiment, affixation of the inside

11 attachment clip 54 to the eave header 42 is achieved via a

12 fastener 122 which is placed through the attachment lip 58 and

13 into the eave plate support section 48. The fastener 122 is

14 typically a screw but may also be a pin, clamp, bolt or even an

15 adhesive .

16 The contacting ear 60 is generally parallel with a leg of

17 the "U" , opposite the attachment lip 58, of the "U" shaped

18 channel 56 but extends below the base of the "U" . In operation,

19 the contacting ear 60 abuts the inside stud 38 and allows the

20 eave header 42/inside attachment clip 54 combination to affix to

21 the inside stud 38/outside stud 32 combination when the aforesaid

22 fastener 122 is secured.

23 For the gable ends of the structural framing system 10, two

24 or more gable headers 62 are placed atop the inside stud

2538/outside stud 32 combination. In a preferred embodiment, the

26 gable headers 62 are placed in a generally 90 degree horizontal

27 relationship with the eave headers 42. The gable headers 62

28 share a somewhat similar geometric cross section with the eave

29 header 42. The gable header 62 is comprised of a first gable

30 plate 64, a second gable plate 66, and a gable plate support

31 section 68. The gable header 62 cross section is formed from a

32 first gable plate 64 and a second gable plate 66 which are

33 positioned approximately 90 degrees relative to each other.

34 Within the portion having said angle is placed a gable plate

35 support section 68. The gable plate support section 68 also

36 forms a support web between the aforesaid plates 64, 66 and

37 thereby reinforces the strength of the header 62. Although the 1 support section 68 may take the form of any shape which helps to

2 support the aforesaid plates 64, 66, in a preferred embodiment,

3 the section 68 forms a substantially right angle. Again, in a

4 preferred embodiment, each gable header 62 is formed as a single

5 header from pultruded fiberglass. Furthermore, in a preferred

6 embodiment, the gable headers 62 are typically used in pairs and

7 placed on two opposing sides of the substantially rectangular

8 form 20 in order to form the gable base for the structural

9 framing system 10.

10 As with the eave headers 42, securing of each gable header

1162 is achieved via the use of an inside attachment clip 54 which

12 holds the header to the outside 32 and inside 38 stud combination

13 via attachment to the gable plate support section 68. The

14 combination of the inside clip 54 and the header 62 forms a gable

15 header channel 70 for utility runs. A channel cover, typically

16 vinyl, is used for enclosure and covering of said channel 70 if

17 not altready covered by drywall or other wallboard type material. 18

19 Upon the installation of the eave headers 42 and gable

20 headers 62 a ridge beam 74 is placed and attached between the two

21 opposing sides of the substantially rectangular form 20

22 containing the gable headers 62. In a preferred embodiment as 23 shown in Fig. 25, the ridge beam 74 is comprised of a ^wT"-shaped 24 member 76 having one or more rest plates 78 at the base of the 25'T". The rest plates 78 are positioned at an angle between 90

26 and 135 degrees relative to the base of the *T" where they are

27 mounted. Onto the rest plates 78 and opposite the base of the

28 mounting point is placed one or more plate ears 79 which are

29 mounted substantially inline with the ^,T" -shaped member 76.

30 Alternative embodiments could have plate ears 79 with any angle

31 relative to the ^w T" -shaped member 76 which the user desires.

32 In a preferred embodiment, placement of the ridge beam 74

33 is accomplished by the removal of the plate ears 79 only on that

34 portion of the ridge beam 74 which rests upon the gable headers

3562. In a preferred embodiment, once the proper length of plate 1 ears 79 are removed, the ridge beam 74 is positioned onto the

2 gable headers 62 generally towards the center of the

3 substantially rectangular form 20. Alternative embodiments may

4 position the ridge beam 74 onto any portion of the gable headers

542 which s desired by the user. Upon positioning, the ridge

6 beam 74 is secured to the gable headers 42 with fasteners 122

7 wherever the user deems appropriate. In a preferred embodiment, 8a ridge beam cover, typically vinyl, is placed between the plate 9 ears 79 opposite the rest plates 78 _f _~ sρ_ <_ c. ^< _^uu

10

ll'ur =5 n 1. This allows the volume defined by the rest

12 plates 78 and plate ears 79 to serve as an area for utility runs.

13 Again, m a preferred embodiment, each ridge beam 74 is formed

14 as a single beam from pultruded fiberglass.

15 In some applications, a longer and stiffer ridge beam may

16 be desirable. An alternative embodiment of the ridge beam 74

17 would be useful m this type of application. An alternative

18 ridge beam 74 is comprised of two fastener joined sections 82

19 between which is sandwiched a flitch plate 92. The flitch plate

2092 is typically manufactured of steel although other structural

21 materials such as aluminum alloy, composites, wood or plastic may

22 be used for the flitch plate 92 as required for the application.

23 The cross section of the fastener joined section 82 is comprised

24 of a first vertical plate 84 onto which is formed a top plate 86.

25 In a preferred form, the top plate 86 generally forms a right

26 angle with the first vertical plate 84. Alternative forms could

27 place the top plate 86 at any angle which is necessary for the

28 application.

29 Onto the first vertical plate 84 and opposite the top plate

3086 is formed a bottom channel plate 90 having a bottom channel

31 ear 91 m a preferred form. The bottom channel plate 90 is

32 generally positioned m a 90 degree relation to the first

33 vertical plate 84 in a preferred form. Alternative forms may

34 have any angle which is most desirable for the application. Between the top plate 86 and the bottom channel plate 90 is formed a rest plate 88. The rest plate 88 typically forms a minor angle with the first vertical plate 84 between 40 and 90 degrees, depending on the desired pitch of the roof of the structural framing system 10. The alternative embodiment of the ridge beam 74 which contains the flitch plate 92 is typically placed and fastener mounted onto steel columns 98 at the gable ends of the structural framing system 10, although column studs 94 may also be used. The bottom channel plate 90 of the alternative embodiment of the ridge beam 74 is typically placed onto the steel columns 98 and secured with fasteners 122. The ridge beam 74 position is generally towards the center of the substantially rectangular form 20. Further alternative embodiments may position the alternative ridge beam 74 onto any portion of the gable end which is required by the application. Support is provided on the ends of the ridge beam 74 by column studs 94 or steel columns 98. The column studs 74 replace the outside studs 32 under the gable header 62 where the ridge beam 74 is located. Each column stud 74 has substantially the same outside cross section as the outside stud 32 with the exception that the substantially rectangular and hollow cross section 34 has a thickened rectangular wall 96. In a preferred embodiment , each column stud 74 is formed as a single stud from pultruded fiberglass. If further support is required for the ridge beam 74, one or more column studs 94 or steel columns 98 are located under the ridge beam 74 at various points within the structural framing system 10. In an alternative embodiment, especially where building codes or strength requirements dictate, steel columns 98 are used to support the ridge beam as an alternative to the column studs 94. When steel columns 98 are used, typically channels 120 are positioned and secured next to the steel column 98. This provides a secure interface of the gable headers 62 with the intersection point of the steel column 198, ridge beam 74 and gable headers 62.

2 Upon installation of the ridge beam 74 and its supporting

3 columns 98 or studs 94, a plurality of rafters 100 are placed and

4 attached between the ridge beam 74 and the eave headers 42. Each

5 rafter 100 rests upon the first eave plate 44 and the rest plate,

678 or 88, of the ridge beam 74. Again, each rafter is secured

7 with fasteners 122 to the ridge beam 74 and the eave header 42.

8 In a preferred embodiment, each rafter 100 is separated by 24

9 inches, center to center, but may be separated by any width 0 required by the application. 1 In a preferred embodiment, the rafter 100 cross section is 2 formed as a substantially inverted ^λΛT" shaped form 102 with an 3 attaching rafter clip 108 located at the topmost portion of the 4 inverted ^w T" . The substantially inverted ^WT" shaped form 102 5 contains a thickened top boss portion 104 which allows for 6 fasteners 122 to be placed into it for securing of the rafter 7 clips 108. Further securing of the rafter clip 108 is provided 8 by a lengthwise notch 106 on the thickened top boss portion 104 9 of the rafter 100. In a preferred embodiment, each rafter 100 0 is formed as a single rafter from pultruded fiberglass. 1 Each rafter clip 108 is formed as a substantially flat plate 2110 with a center rib 112. The center rib 112 fits integrally 3 with the lengthwise notch 106 of the rafter 100 to help secure 4 the rafter clip 108 to the rafter 100. In a preferred 5 embodiment, each rafter clip 108 is formed as a single pultruded 6 fiberglass plate. Before the rafter clip 108 is secured to the 7 rafter 100, a roofing panel or insulation 118 is typically placed 8 into the area formed by the ears of the ^w T" 102 and the rafter 9 clip 108. Once fastened, the rafter clip 108 helps to hold and 0 secure the roofing panel or insulation 118 in place. 1 At each gable end of the structural framing system 10, an 2 end rafter 114 is used in place of the rafter 100 and fits 3 between the ridge beam 74 and the eave header 42 as a typical rafter 100. The end rafter 114 has substantially the same cross section as the rafter 100 with the exception of its cross section having a substantially ^λL" shaped form 116. The ear of the ^,L" shape 116 is placed toward the internal portion 22 of the substantially rectangular form 20 when installed and functions the same as the ^*T" 102 of the rafter 100. Use of this end rafter 114 prevents unwanted overhang near the external portion 24 of the substantially rectangular form 20 at the gable ends and also brings outside closure to the edge of the structure within the rafter plane. Again, in a preferred embodiment, each end rafter 114 is formed as a single pultruded fiberglass rafter. A rafter clip 108 is placed onto each end rafter 114 in the same manner as with the rafters 100 in order to sandwich and hold roofing panels and/or insulation material 118. An alternative embodiment would replace the structure defined by the ridge beam 74, the rafters 100, and the end rafters 114 with a plurality of roof trusses 126. Each roof truss 126 rests upon opposing eave headers 42 and spans the entire width of the structure. Each roof truss 126 is secured to the eave header 42 by means of a truss clip 130 which is secured to each member by means of fasteners 122. The roof truss 126 is of conventional design and preferably formed from plurality of rectangular pultruded members having a hollow cross section 128 and connected with fasteners and/or plates. The exact angular placement of the rectangular members 128 within the truss 126 form can vary substantially in a conventional truss design as described here. Should the user desire window or door framing, a plurality of window and door channels 120 are provided. Each window and door channel 120 is of substantially ^λ,C" shaped cross section and in a preferred embodiment formed as a single pultruded fiberglass channel. Each channel 120 is mounted vertically and/or horizontally where necessary to form a generally rectangular frame and is cut to the required length when placed. The channels 120 function much as conventional framing lumber with the exception that they offer all of the advantages of pultruded fiberglass in a preferred embodiment. An angle 124 is typically placed at the intersection of each channel 120 and secured with fasteners 122 in order to secure each channel 120. Although the preferred embodiments of the structural framing system described herein would utilize a pultruded fiberglass material, the structural framing system of the present art may be manufactured of a variety of materials, including but not limited to wood, plastic, steel, aluminum, or other composite materials. The preferred and alternative embodiments described herein may also be manufactured in different sizes and colors.

All of the aforementioned structural components are fastened together in their respective locations with the use of conventional fasteners 122 such as sheet metal screws, machine screws, nuts, and concrete anchor bolts, but may also be fastened using other types fasteners such as pins, studs or clamps or with the use of specialty adhesives. In a preferred embodiment, the fasteners are comprised of #10 sheet metal screws except for fastening of the column studs, ridge beam, flitch plate and associated beam, end rafters, and roof rafters which use ^-20 machine screws for fastening. Upon assembly of the structural framing system 10, the external 24 and the internal 24 portions may be finished as the user desires. That is, if exterior siding is desired, it may be attached to the outside studs 32 as in conventional framing systems. If interior drywall is desired, it may also be attached to the inside studs 38 as in conventional framing systems. Again typically fasteners 122 are used for the attachment. Provisions have been made and described herein for utility runs such as electric and water. From the foregoing description those skilled in the art will appreciate that all objects of the present invention are realized. An structural framing system and method of assembly lbeen shown and described which permits a user to provide a

2 strong, and weather and corrosion resistant, frame for a house,

3 shed or shelter with a minimum of skilled labor or specialty

4 tools. The art of this invention in its preferred pultruded

5 form is able to withstand severe wind, temperature and corrosion

6 conditions and yet provide a comfortable shelter. T h e

7 present invention, in alternate embodiments with the unique cross

8 sections described, provides for the use of materials other than 9 pultruded fiberglass when the conditions require.

10 Having described the invention in detail, those skilled in lithe art will appreciate that modifications may be made of the

12 invention without departing from its spirit. Therefore, it is

13 not intended that the scope of the invention be limited to the

14 specific embodiments illustrated and described. Rather it is

15 intended that the scope of this invention be determined by the

16 appended claims and their equivalents. 17
