8 Claims. (Cl. 189-44) This. invention relates in general to building structures and more particularly to prefabricated houses or dwellings.

One of the objects of the invention is to provide a building structure of this character which is made up for the most part of units or sections fabricated at the factory and susceptible of convenienterection or assembly at the point where the house is built. The units are such that they may be readily handled during transportation and easily and quickly assembled at the place :of erection.

One of the outstanding features of the invention is that the units which go to make up the major elements of the house namely, the walls, floors, ceilings, and roof, are framed in -steel at the factory and equipped and designed to be interlocked in a. permanent and secure fashion at the place where the house is built.

Along with these advantages the house is so constructed and organized as to be susceptible of being built and maintained at a low cost, provide for the maximum use of space, be resistant to fire, wind, earthquake and weather, well insulated, lightning safe and vermin proof.

Furthermore, the construction is such as to be adaptable to a variety of floor plans and architectural styles. 7

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification, and in which:

may be compactly packaged for shipment and f welded to the side channels.

structural units are stamped from sheet steel.

Referring to the drawings it will' be seen that the present invention proposes to constitute the framing of the walls, floors, ceilings, caves, and roof of prefabricated steel panels.

The framing panels, while differing in some 5 respects to adapt them to. serve their individual purposes have certain structural features in common in that they comprise generally side channels and end channels extending between and The panels are assembled with their adjacent side channels abutting in face to face relation and are securely fastened together when so erected.

The floor panels designated generally at F are all of similar construction and,-as shown to advantage in Figures 2 to 5 inclusive, each includes; side channels I and end channels 2 extending between and welded to the side channels. All of the channels incorporated in the various At regular intervals along each floor panel cross channels 3 are provided, the cross. channels 3 paralleling the end channels and being disposed at right angles to the side channels. The ends of the cross channels are welded to. the side channels. The cross channels open or face upwardly and receive wooden furring strips 4.

Portions of the side flanges of each cross channel Y 3 are displaced or upset inwardly as indicated at 5 in Figures 3 and 4 to secure the furring strips in place. The furring strips project upwardly beyond the edges of the side flangesof their cross channels and their top surfaces are co-planar with the top surfaces of the upper side flanges of the side and end channels. Subflooring designated at 6 issecured by nails 1 to the furring strips 4. The body portions of the cross channels 3 are depressed or convexed downwardly as at- 8 to strengthen these cross'channels and to accommodate the ends of the nails 1 which penetrate the furring strips and project downwardly therebeyond.

The floor panels F are completed in the man-. ner just described at the factory and obviously they may be stacked and compactly crated.

At the place where the house is erected the floor panels are laid on a suitable foundation, for example on a concrete foundation, a-portion' of which is designated at 9 in Figure 5, and on suitable beams, a fragment of one of which is shown'at II) in Figure 5. Bolts II are embedded in the foundation 9 and project upwardly therefrom. Nuts I 2 threaded on the bolts H and engaging tie plates l3 serve to secure the floor panels in place. ,The tie plates overlap the lower flanges of the floor panels at the corners thereof as shown. Bolts and nuts It may be employed to directly secure the lower side flanges of the channels of the panels to the beam l0.

Bolts and nuts |4' or other suitable fastening devices are employed to permanently fasten together the abutting surfaces of the side walls of the floor panels and in instances where the end channels of floorpanels abut they are similarly secured together.

The framing for the walls of the house is'also made up of sheet metal framing panels designated generally'at W. As shown in Figure 1 the wall panels W are all of similar construction in that each includes side channels l5 and end channels l6 extending between and welded to the side channels. Except where provision is made for a door or window each of the wall panels has a plurality of intermediate longitudinally extending channels I! paralleling the side channels and having their ends welded to the end channels l6. Where a window is to :be provided, appropriately spaced cross channels [8 are incorporated in the structure of the panel and extend between and are welded to the side channels l5, and are braced and strengthened by longitudinally extending channels I9 of appropriate length, the channels l9 extending between and-being welded to the cross channels l8 and end channels It as shown in the drawings.

The eaves framing panels designated generally at E, roofing framing panels R, and gable framing panels G are similarly constituted although difierently dimensioned to adapt them to fulfill their respective purposes. One of the roof framing panels is provided with a trap door opening .T and certain of the roof framing panels are formed with projections P to provide the framing for the porch roof. All of the framing panels however are constituted of the side and end channels welded together and where desirable equipped with suitable cross channels.

When the house is erected the wall panels, roofing panels, eaves panels, and gable framing panels are assembled with their adjacent side flanges abutting in face to face relation and they are appropriately welded together or interlocked. The abutting faces of the channels of each panel are provided with slots which register .in the assembly. Anchoring lugs 21 are provided and extend through these registering slots, the lugs having feet 28 abutting one of the channels and having an aperture 29 in the portion thereof which projects beyond the other. A tapered key 30 is driven into the aperture 29 and frictionally and tightly engages or wedges itself in the aperture 29 and against the adjacent channel to secure or interlock the panels together in a permanent fashion. Ifdesired, the anchoring lugs may be spot welded at as 21' to one of. the panels.

The exterior of the metal panels W making up the walls are sheathed or covered with two layers of moisture proof structural or. building board designated at 22 and 22'] In instances where the floor panels. are used on an upper floor they are adapted to serve as a support for the ceiling of the next lower floor and this is accomplished by providing the fioor panels of the character previously described with downwardly facing or opening cross channels 3' (see the upper portion of Figure 5), similar in all respects to the channels 3 except that they are disposed adjacent the bottom of the floor panel and face downwardly. Furring strips 4' are combined with the cross channels 3 in the same way that the furring strips 4 are combined with cross channels 3. The ceiling is preferably constituted of sheets of heavy gypsum board designated at 35 and secured by nails 1' to the inning strips 4'.

If desirable, the joints covered by the batten strips 65 at the corners and also between the wall panels may be sealed with mastic.

It is to be understood that the gypsum board 'It is proposed to finish this trim with baked enamel at the factory so that no painting will be required on the job. In Figure 5 the base board trim is designated at I5 and has hook formations I6 and 11 along its upper and lower edges designed to interlock with clips 18 secured by screws 19 to the metal framing panels.

The subflooring with which the floor panels are equipped at the factory is at the time of the erection of the house covered with a layer of heavy felt and, in the living room, dining room,

bedrooms and hallways, finished with suitable hard wood flooring. The kitchen and bathrooms may be covered with linoleum or rubber tile.

It is to be understood that the particular house i plan shown in Figure 1 is only one of many that may be resorted to in carrying out the present in- ;vention. As previously indicated, the structure lends itself to a great variety of floor plans andarchitectural styles.

While I have shown and described one construction in which the invention may be advantageously embodied, it is to be understood that the construction shown has been selected merely forthe purpose of illustration or example and that various changes in the size, shape and arrangement of the parts may be made without departing from the spirit of the invention or the scope of the subjoined claims.
