Serial No. 517,930 2 Claims. (01. 189-85) This invention relates generally to means for supporting insulating materials in building 0011- structions and refers more particularly to the provision of means of the above typein the form 5 'of metallic foundation sheets especially designed to support insulating materials having aocoustical and/or heat insulating properties.

One of the prinipal objects of this invention is to support the insulating materials from the sheets in spaced relation to the major or body portions of the latter so as to provide an air chamber therebetween which serves to enhance the acoustical and/or heat insulating properties of the construction and also to maintain these properties over a long period of use.

Another advantageous feature of this invention resides in the provision of metallic foundation sheets having laterally extending flanges provided with shoulders cooperating with suitable fastener means for attaching the sheets to a support and further operable to support the insulating materials from the sheets in the manner specified above.

With the foregoing as well as other objects in view, the invention resides in the peculiar construction of the nietallic foundation plates which will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein: Figure 1 is a cross sectional view through several foundation sheets showing one method which may be employed for supporting the heat insulating materials upon the sheets and also a method for attaching the sheets to a support;

Figure 2 is a fragmentary side elevation taken substantially on the line 2-2 of Figure 1;

- Figures 3, .4, 5, 6, '7 and B are views similar to Figure 1 showing modified forms of metallic foundation sheets;

Figures 9, 10, 11, 12 and 13 are fragmentary perspective views of the metallic foundation sheets shown respectively in Figures 4, 5, 6, 7 and 8.

While the underlying inventive principles involved herein may be accomplished by numerous different constructions and while several modifications of the invention are illustrated herein, it will be apparent as this description proceeds that in each modification the insulating materialis supported from the metallic foundation sheets in 50 spaced relation to the .maioror body portions of i the sheets so as to create an air chamber between adjacent surfaces of the sheets and insulating material. It has been found that by reason of the air chamber as specified, the acoustical and/or heat insulating properties of the unit are enhanced and also that the aforesaid properties of the insulating material itself are maintained over a long period of time. These features may be attributed to the fact that the air chamber provides for a circulation of air between the adjacent surfaces of the insulating material and sheets, thereby preventing the accumulation of dust upon the inner surface of the insulating material and as a consequence maintain the pores of the material open at all times. Moreover, by reason of the novel manner in which the insulating material is supported from the sheets, a saving in the amount of insulating material is realized. In other words, with the present invention a relatively great areaof space may be invsulated with a comparatively small amount of material. A further advantage derived by virtue of the air chamber hereinbefore described is realized in a construction'wherein the body portions of the metallic foundation sheets are apertured since with such an arrangement there is less likelihood of paint or the like penetrating the insulating material and closing the pores therein during the process of decorating the outer surfaces of the foundation sheets.

Referring now more in detail to the several constructions illustrated herein and with special reference to Figures 1 and 2, it will be noted that I have shown a plurality of metallic foundation sheets 15 preferably developed from sheet metal and having substantially straight body portions 16 suspended from suitable purlins 17 in spaced relation thereto by fastener elements 18. The sheets 15 are suspended from the purlins 17 in juxtaposition to each other and in such a manner that the outer surfaces of adjacent sheets are substantially continuous and flush with each other. As shown, the sheets 15 preferably extend longitudinally of the purlins 1'! and the joints between the longitudinal edges of adjacent sheets are preferably located directly beneath the purlins for reasons to be presently described.

The longitudinal side edges of the sheets 15 are bent laterally to form flanges 19 adapted in the assembled position of the sheets to project toward the purlins 17. The flanges 19 are bent intermediate the ends thereof to provide inwardly triangularly shaped grooves 20 forming shoulders 21 preferablg spaced a uniform distance from the body portions 16 of the sheets. The above arrangement is such that when a pair of sheets are arranged in juxtaposition as shown in Figure 1, the grooves 20 register with each other and the shoulders 21 assume a position substantially lnalignment. The fastener elements 110 18 are also preferably formed of sheet metal having the upper ends thereof anchored to the purlins 17 in longitudinal spaced relation and having the lower ends bent to form triangularly shaped portions adapted to extend within the registering grooves 20 to engage the lower surfaces of the aligned shoulders 21 as clearly shown in Figure 1 of the drawings. Thus, it will be ob served that the foundation sheets are suspended from the purlins 17 in such a manner that the bottom surfaces thereof lie substantially flush forming, in effect, a continuous surface.

Referring now more in detail to the insulating material, it will be noted that this material is in the form of sheets 23 elongated in the direction of the length of the purlins and foundation sheets and having the opposite marginal longitudinal edge portions 24 overlapping the upper surfaces of the shoulders 21 and seated thereon. Since it has been previously pointed out that the shoulders 21 are spaced above the body portions 16 of the foundation sheets, it will be apparent that the insulating material 23 is supported in spaced relation above the body portions 16 providing an air chamber 25 between adjacent surfaces 26 and 27, respectively, of the insulating and foundation sheets which is desirable for reasons hereinbefore stated. Owing to the particular configuration of the flanges 19 on the sheets, it will be apparent from Figure 1 that the distance between the shoulders 21 of each sheet is less than the width of the body portion 16, thereby permitting the use of insulating sheets having a width substantially less than the body portions 16 of the foundation sheets. With the above construction, it will readily be seen that a relatively great area of space may be insulated with a comparatively small amount of insulating material, thereby effecting a saving of insulating material and accordingly reducing the cost of installation. As will be observed from Figure 1 lateral shifting of the insulating sheets 23 relative to the foundation sheets 15 is restricted by the portions of the flanges 19 above the shoulders 21 and the joints between adjacent insulating sheets are substantially sealed by the purlins 17.

The construction shown in Figure 3 is identical to the construction hereinbefore described with the exception that the body portions 28 of the foundation sheets are provided with a plurality of apertures 29 establishing communication between the interior of the structure and the air space 30. With this latter construction, the provision of an air chamber between'the adjacent surfaces of the insulating material 31 and body portions 28 of the sheets is of particular importance since the outer surfaces of the foundation sheets may be painted or otherwise coated without the danger of the fluid penetrating the downwardly toward each other and are provided with laterally outwardly extending portions forming shoulders 36 having the outer ends the sheets. The shoulders 36 and 40 are spaced above the body portions 39 of the sheets in the same manner as the shoulders 21 hereinbefore described and serve to support the insulating sheets 41. In this connection it is to be noted that a pair of insulating sheets 41 is provided for each foundation sheet and the marginal longitudinal edge portions of each sheet are supported respectively by the shoulders 36 on the hollow reinforcing ribs and the shoulders 40 on the side flanges 34. In other words, a sheet of insulating material is arranged upon opposite sides of each reinforcing rib 33 and since the shoulders 36 and'40 bear the same relationship to the body portions 39 of the sheets as the flanges 21 in the first-described form of the invention, it will be apparent that an air chamber 42 is also provided in the present instance between the adjacent sur faces of the insulating material and foundation sheet. It will further be apparent that the construction shown in Figure 4 offers the same possibilities of saving insulatingmaterial as the construction shown in Figure 1.

The foundation .sheets 45 shown in Figure 5 are bent intermediate the ends thereof to form a substantially T-shaped hollow reinforcing rib 46 with the head of the T arranged uppermost and the legs 4'7 thereof merging into the body portions 48 of the sheets. The opposite longitudinal edges of the sheets are bent laterally in the direction of the reinforcing rib to provide flanges 49 fashioned intermediate the ends thereof to form inwardly extending substantially channelshaped grooves 50 adapted to register with each other in the assembled relation of the sheets to receive the fastening means 51. The fastening means 51 serves to suspend the sheets from the purlins 52 in the same manner as the fastening means 18, hereinbefore described, and is provided at the lower ends thereof with laterally and oppositely extending lugs 53 adapted to extend within adjacent grooves 50 and engage the lower surfaces of the shoulders 54 formed by bending the flanges 49 as stated. The shoulders 54 are spaced above the body portions 46 of the sheets and the outer surfaces thereof function to support the outer longitudinal marginal edge portions of the insulating sheets 55. There are two insulating sheets 55 for each foundation sheet 45, one upon each side of the reinforcing ribs 46 and the inner longitudinal marginal edges of the insulating sheets 55 are supported from the ribs 46 by means of a clip 56. In detail, the clip 56 is provided with an inverted channel-shaped portion 57 adapted to receive the head of the T-shaped rib. The clip is further provided with shoulders 58 projecting laterally outwardly from the legs of the channel-shaped portion 57 and terminating in downwardly and inwardly inclined flexible portions 59. The shoulders 58, specified above, and the shoulders 54 on the flanges are arranged in a common plane substantially parallel to the body portions 48 of the sheets and spaced above the same for supporting the adjacent marginal edge portions of the insulating sheets 55 in spaced relation to the body portions of the foundation sheets.

The insulating sheets 60 illustrated in Figure 6 are supported from the foundation sheets 61 in the same manner as the sheets 55 described in connection with the above modification. The .essential difference between the construction of the foundation sheets 61 and the sheets 45 just described is the particular configuration of the reinforcing ribs 62 and spring clips 63. As shown in Figure 6, the hollow reinforcing ribs 62 are substantially channel-shaped in cross section with the legs of the channel located in close proximity to each other and merging into the body portions 64 of the sheets. The clips 63 conform substantially to the shape of the ribs 62 and are provided with transversely oppositely extendingshoulders cooperating with the shoulders on the side flanges 65 to support the insulating sheets "60 in spaced relation to the body portions 64 of the sheets 61.

The foundation sheet 66 illustrated in Figure 0 7 is similar in construction to the foundation sheets 32 illustrated in Figure 4, but differs from the latter in that the hollow reinforcing rib 67 is not formed with shoulders for supporting the adjacent marginal edge portions of the insulating sheets 68. Instead of forming shoulders integral withthe hollow reinforcing rib 67, a spring clip 69 is provided adapted to be sprung overthe upper portions of the reinforcing rib 6'7 and pro-' vided with shoulders '70 adjacent the lower ends thereof. The shoulders 70 project laterally outwardly from opposite sides of the reinforcing rib and terminate in downwardly and inwardly extending flanges '71 which serve to support the shoulders 70. As will be readily apparent from Figure 7, the shoulders 70 cooperate with the shoulders 72 on the side flanges '73 for supporting the insulating sheets 68 within the foundation sheets in spaced relation to the body portions thereof.

The modified form of construction illustrated in Figure 8 differs from either of the above described constructions in that the side flanges '15 of the foundation sheets '76 are bent intermediate theends thereof to form substantially semi-cir:

4 5 cular recesses 76' cooperating with each other in the assembled relation of the sheets to receive the circular head portions '77 of the fastener elements 78. The fastener elements '78 are secured to the purlins '79 in the same manner as the fastener elements hereinbefore described. The foundation sheets '76 are bent intermediate the ends thereof to form circular reinforcing ribs 80 and suitable insulating sheets 81 are arranged ,within thefoundation sheets upon opposite sides of the reinforcing rib 80. The lower longitudinal tially parallel to the plane of the body portion the body portion.

edge portions of the insulating sheets 81 adjacentthe flanges '75 are arcuate in shape and are adapted to seat upon the arcuate shoulders 82 formed by bending portions of the flanges inwardly as stated above. The adjacent marginal edge portions of the insulating sheets 81 are seated upon shoulders 83 projecting laterally outwardly from opposite sides of the rib. While the shoulders 83 may be formed integral withthe rib,

I have illustrated the same herein as forming a part of the clip 84 which is adapted to be placed over the rib as shown in Figures 8 and 13. The shoulders 82 and 83 are so arranged as to support the insulating sheets in spaced relation to the body portions of the foundation sheets to provide air chambers therebetween.

Thus, from the foregoing it will be apparent that while various forms of foundation sheets have been illustrated and described herein for supporting insulating sheets within a building construction, nevertheless, in each modification the insulating material is so supported that an air space is created between adjacent surfaces oi the insulating material and foundation sheets. It will, further be seen that each of the above described constructions permits utilizing insulating material of less width thanthe overall width of the body portion of the sheets thereby effecting .foundation'sheet having a body portion and having a reinforcing rib bent out of the plane of the body portion, and a clip attachable to the reinforcing rib and having shoulders projecting laterally outwardly from opposite sides thereof located in spaced relation to the body portion aforesaid and operableto support adjacent marginal edge portions of insulating sheets.
