Patents NOS. 1,825,346, 1,964,728, 1,989,798 and 2,001,605, and aims to improve the construction thereof and to provide a rigid skeleton frame and improved connections between the floor and wall sections and frame for such buildings.

An important object of the invention is to lessen the cost of constructing and erecting buildings of the fire-resisting type Without'sacrificing strength, watertightness and long serviceability.

The invention also aims to improve the wall construction by providing adequate and uniform weatherproofing and heat and sound insulation throughout the entire area while permitting use of such exterior and interior nish as may be desired.

For residences, schools,v apartments, hospitals and other lightly loaded types of buildings, the skeleton frame is advantageously constructed with steel columns, girders and beams for supporting the floors and walls and resisting wind Thomas J. Foster, Ridgewood, N. I.

1935, Serial No. 44,264

(Cl. 'l2- 1) pressure, wholly prefabricated from channels, angles and light weight I-beams connected by interengaging parts formed integral therewith or. welded thereto, as described in my copending application Serial No. 723,985, thereby eliminating any welding or riveting when the frame is erected, although a riveted or welded steel frame may be used if desired.

` The frame construction illustrated comprises columns II supporting girders I2 and iloor beams I3 arranged in parallel bays, the beams I3 being spaced about four feet apart and extending from girder to girder with their top flanges level with the top flanges of the girders. Preferably the corner columns areangles with the outer faces of the legs facing outward, and provided at each floor level with an interior ang'le I4 Welded thereto for supporting the ends of the beams and girders. The edges of the columns and the angles I4 are welded edge to edge, as shown in Figs. 1 and 6, and the angle brackets I5 which support the beams and girders are welded to the adjacent faces of the column angles. webs of the girders and beams are notched to provide hook shaped supports for engaging over the brackets I5 and interlocking with openings therein to hold them securely in place. Such columns, girders and beams may be completely fabricated in advance of reaching the job, and readily assembled and secured in place without special tools or skilled workers such as Welders and riveters, thereby saving much of the expense. of erecting a steel frame for buildings of this type.

Various forms of prefabricated sections for the floors and walls may be secured to the skeleton frame, depending upon the purpose for which the building is to be used or the architectural treatment desired. In-the floor construction illustrated in Figs. 1 and 2, each section comprises a series of layers adhering together and strengthened by sleepers or cross-supports 2l made of wood or other suitable materials and supported at their ends on vibration absorbing and heat insulating cushions or springs 22 which may rest directly over the top anges of the frame members I2, I3. In the forms of construction more clearly shown in Figs. 2 and 3, the transverse supporting members 2l are faced on their under sides with strips of felt 23, and in the construction shown in Fig. 2 they are covered on their upper sides with a continuous layer of felt 24, or similar insulating material. Any suitable oor finish may be applied to the top face of the panel, that illustrated in Fig. 2 being a hard The ends of the wood floor to which the felt 24 is cemented on its under side, and that illustrated in Fig. 3 being a thin concrete plate 26 with embedded reinforcement 21 and faced with linoleum 28 secured thereto by a layer of suitable adhesive 29. A continuous sheet of heavy paper or like insulating material is advantageously placed over the supports 2| for supporting the concrete layer when being formed and for additional heat and sound insulation between the iioor and ceiling.

In both forms of floor slab a heat and sound proof ceiling is secured beneath the transverse supports in such manner as not to transmit vibration thereto. This ceiling may consist of a plaster board finish 30 or any suitable ceiling finish upon which is poured a layer of aerated gypsum or any light plastic material 3l embedding a wire mesh or other suitable reinforcement 32 attached to the underside of the transverse supports by staples 33 passing through felt washers 34. If desired, for additional heat insulation, the space between the ceiling and floor may be partly lled by rock wool 35, as shown in Fig. 2. Polished sheet metal constituting soundand heat reflecting surfaces 36 may be substituted for the rock wool, if desired, as shown in Fig. 3, or this may be omitted entirely.

The door slab or panel illustrated in Figs. 4 and 5 is suitable where a fire proof ceiling is not important, no gypsum or rock wool being used. The layer of felt Ztl cemented on the under side of the flooring 2li provides substantial sound and heat proofing, and the plaster board or ply wood layer 3B adhesively secured beneath the crosssupports 31 provides additional sound proofing as well as heat insulation.

The wall panels advantageously have wall board or plaster board or ply-wood inner faces 40 and cement, stucco, or other suitable exterior finish 4l on the outer faces, depending on the type of building and eiect desired. These panels are reinforced by channel-shaped open work metal reinforcement 42 surrounding the edges and crossing the panel intermediate the edges at suitable intervals, the anges being embedded in the bor material of the panel to tie the faces together. Aerated gypsum, or other light heat insulating material, is advantageously used for the inner body portion 43 of the exterior wall panels, and cement or concrete for the outer body portion lill, the intervening space being filled with rock wool t5, or left open, as desired. Heat and sound reecting surfaces like the polished metal sheets 36 shown in Fig. 3 may be used on the inner sides of the faces 43, it in place of the insulation R5. The entire body layer Ml is preferably stifiened with reticulated sheet metal or wire mesh sections 38 backed by a layer of waterproof paper 33.

At the ends of the wall panels the cement or concrete layer is preferably thickened at the places where it is to fasten to the steel frame, as shown in Fig. 4, and the wall panels are supported at their lower ends on steel plates or bars 4E welded to the flanges of the adjacent beams or girders, being held in position by dowels or pins 41 which engage in suitable recesses formed in the lower ends of the upper tier of panels and in the upper ends of the lower tier of panels. Lag screws 48 extending through the web of the adjacent beam or girder into spaced wood blocks 49 embedded in the inner layer of .plastic material (see Figs. 1 and 4) secure the wall panels to the steel structure and also prevent twisting of the beam or girders due to the weight of the panels on the supports 46. The joints 50 between the lower ends of the upper panels and the upper ends of the lower -panels may be filled with cement or other plastic waterproof material to embed the supports and fill the space to keep out the Weather.

'I'he floor slabs are preferably held in place at their ends by suitable fastenings secured to the beams. In the form shown in Figs. 1 and 7, metal clips 5l are provided having their ends bent around the upper flanges of the beam and an intermediate part doubled up between the ends of the slabs. These clips may be suitably spaced to line up with the ends of the transverse supporting members v2| in adjacent panels and secured to the first panel laid by nails or screws driven through the clips into the transverse members before the next panel is put in place. As the succeeding slabs are laid in place they may be toe-nailed to the preceding ones by nails driven through the ends of the abutting transverse members and concealed beneath the iiooring. The cracks between the abutting ends of the panels may be lled with plastic material, strips of wood, or other heat and sound proof packing.

rIhe clips 55 shown in Fig. 8 may be stamped from sheet steel and nailed to the ends of the side stiiener bars in each panel as laid.

The open sides of the I-beams between the top and bottom ianges are preferably covered with strips of sheet rock 52 nailed to blocks 53 held in place on opposite sides of the beams by bolts or adhesive.

Further details of the panel and slab designs and methods of constructing them will be found in my Patents Nos. 1,825,346, 1,964,728, 1,989,- 798 and 2,001,605, and in my pending application Serial No. 740,705, filed August 20, 1934, for manufacture of cementitious slabs; and further details of the joints and connections between the columnsgirders and beams will be found in my pending application Serial No. 723,985, filed May 4, 1934, for metal framing for building construction.

My invention is applicable to buildings of various kinds by suitable changes in the slabs and panels to adapt them to the conditions of use. For residences where the basement is dry and ordinarily quiet, the damp-proofing and noiseproof ceiling may be omitted. For hospitals, additional noise-proofing may be secured by greater thickness of the ceiling layers and more felt in the sub-oor combined with a rubber tile or other form of silent iioor surface. Roof finishes may be adapted to the size and purpose of the respective rooms by utilizing different floor and wall materials, such as various kinds of hardwood flooring, tile, rubber, linoleum, terrazza, cement and other plastic substances, and ply-wood, sheetrock, wallboard, plaster, canvas, paper and other sheet material suitable for painting or decorating on the interior walls, or waterproof wearing surfaces of stucco, wood, metal, composition, cement or slate for exterior wall and roof panels.

The laminated construction of the slab and panel sections in the floors, walls and roof, provides an effective insulation against sound by causing the vibrations to pass from dense v'to rarer media and vice versa, and as heat and sound have different vibration characteristics and periods, materials may be selected because of their heat insulating or sound insulating properties, as desired.I

The absence of solid metallic connections extending through the section is an important feature of my invention because of its effect on the sound and heat proof properties, there being nothing to conduct the sound and heat from one face to the other; and the thickness of the several insulating layers being the same throughout the entire area contributes to satisfactory service and low cost4 of maintenance.

The connections between the slab and panel sections and the frame members serve to stiffen the latter and take the place of wind bracing. These connections are quickly made without special tools, and if it is desired to strengthen the frame against extraordinary storms or earthquake shocks, the joints may be welded after the frame has been completely assembled and lined up before the panels and slabs are placed, at comparatively small expense. y

It is evident that my invention provides for uniform heat and sound insulation in controllable measure' throughout the entire section to suit its purpose as wall or roof or floor slab or panel,

and at the same time provides a wall panel with an interior surface that is pleasing in appearance and easily decorated and maintained andv an exterior surface that is impervious to rain and not injured by frost, and provides a floor slab made of strong materials of little weight with a Wide variety of iloor and ceiling finishes, all said sections being made of cheap materials, simple of construction and light enough to be easily handled and assembled in a building.
