, 6 Claims.

This invention relates to improvements in building construction and more particularly to novel building structural elements and method of assembling same in a new building system.

In my prior Patents No. 1,877,898 of September 20, 1932, Building construction and 1,968,045 of July 31, 1934, Building construction, therehave been disclosed structures and methods of erect ing same in which self-supporting structural building units are adapted to be keyed together to form walls, ceilings and floors and completed building structures. These structures are characterized by distinct economies in fabrication and assembly and permit the utilization of structura1, cementitiousplastics and aggregates with metallic skeleton constructions, the skeleton of the structure being formed of self-sustaining and self-supporting structural unit members. For certain structural purposes it is desired to 20 erect building structures with a minimal amount of structural cementitious plastic material, and this is accomplished by forming a skeleton metallic structure of novel and improved structural elements in new and structurally efficient combinations whereby a minimum amount of metallic skeleton material is made use of without in any way-sacrificing structural strength in a resulting building structure. The novel structures herein may be readily assembled and 0 the parts thereof, whether preformed units or parts thereof, quickly secured together in 'operative relationship, the walls and floors being rapidly and securely joined by the improvements to be discussed more fully hereinafter. In addition, floor, wall and ceiling panel units may be preformed in any desired sizes and of any desired structural materials and set up and locked in place after the skeleton of the building has been erected. The various panel units may be preformed, or, if desired, may be formed in place, in the several structures.

It is a feature of the present invention to provide an improved building system' comprising continuous wall, floor and ceiling supporting units and parts.

It is also a feature of this invention to provide a building assembly in which the walls, floors and ceilings are generally adapted to be secured together by pin and bolt members.

Another feature; of novelty of the present invention resides in the fact that wall, ceiling and floor members are so configured and arranged as to permit the automatic locking in place of a variety of panel members to form finished Wall, floor and ceiling surfacings,

Yet another feature of novelty of the present invention is the provision of separate panellings adapted for cooperative association with wall, floor and ceiling structural support members, which panellings may be preformed with desired surfacings, or .have desired surfacings applied thereto when erected in place in the structures.

It is also a feature of novelty of the present invention to provide improved wall-supporting structural members and studding-members, to-

gether with floor-supporting members secured thereto and arranged at desired floor levels.

Another feature of novelty of the present invention is the provision of improved floor-supporting members including novel truss constructions and connections between walls and floors, including hinge-joint types of construction.

Other features of novelty of the present invention, include spacing and supporting members of novel design, as well as keying or locking members adapted for use with panellings or 0 surfacings of various types and which are further adapted to be permanently locked in place with studding, beam, joist members, plate girders, trusses, and other structural supporting members. c.

These and other desirable features and advantages of the present invention will be described in the specification and building system and illustrated' in the accompanying drawings, certain preferred structural members and features being shown by way of illustration only, for, since the underlying principles maybe incorporated in other, structural devices and assemblies, it is not intended to be limited to the features and structures 'here shown, except as such limitations are clearly imposed by the appended claims.

' Fig. 11 is an elevation of the floor-supporting bracket shown in Figs. 9 and .10;

Figs. 12 and 13 are elevations of stud and stanchion members showing hinge connection members.

Referring more specifically to the drawings and with particular reference to Fig. 1, the building walls and associated parts are designated generally by the numeral I00; the floor members and associated structural parts are designated generally by the numeral 200; the ceiling members are designated by the numeral 300; and the roof members and associated parts are designated generally by the numeral 400.

The walls I00 may be formed of a plurality of spaced stud members I I0 supported on structural foundation members I20 adapted to be secured to and associated with basement foundation walls I30, as will be described more in detail hereinafter. The floors 200 may be supported from the studding members by suitable keying members members are secured to the supporting members I40 and I50 by suitable hinge-joint connection members, indicated generally by the number 240.

Considering the several novel features of construction herein, and with particular reference to a preferred method of assembling a building, the foundation and wall construction will first be described. As shown in Figs. 2 and 3, the foundation wall I30 may be made in the usual manner and may comprise a concrete or other basement wall in any suitable fashion. Mounted on the basement foundation and suitably aligned, is a starting and aligning channel and supporting and bearing member. I20 of particular construction, which will be described more in detail hereinafter. The starting and supporting channel I 20 may be secured in place by hook bolts I3I passing through the channel member I20, the latter being held in place by nuts I32 cooperating with the bolts. The bolts are anchored in the concrete or basement foundation by means of anchored members I33, which may be rods or the like, passing through the eye or hook of the bolt I3I. A suitable number of bolt-and-nut members may be embedded in the foundation wall and the starting wall basement members I20 secured thereto in desired alingment.

A cementitious plastic surfacing I34 may be applied to the exterior of the foundation wall or members, although it will, of course, be understood that any suitable surfacing may be applied.

The walls I 00 of the buildings contemplated under the present invention may comprise supporting members IIO forming composite studding mounted on and secured by and to the starting and supporting channel members I20, as will now be described. Referring now more particularly to Figs. 2 and 3, the channels or base members I20 comprise a generally channelshaped member having a bottom portion I2I apertured to receive bolts I3I and to be locked in place by nuts I32 cooperating therewith. The channel members have sides I22 terminating at their upper edges in inturned stiifening and looking flanges I23. The members I20 may also be provided with aligned apertures I24 adapted to receive bolts and nuts I25 for locking composite studding members in place, as will now be de scribed.

The composite studding H0 .01 the present invention comprises a pair of opposed vertical structural supporting members III of generally rectangular or cylindrical shape, or any other desired configuration, which members are slotted longitudinally and are preferably provided with inturned flanges inwardly of the slots, all as indicated at II2, whereby to provide increased stifiening effect in the members as well as to provide locking elements for wall panel constructions to be described more in detail hereinafter. The stud-like or stanchion members or sections III are spaced apart and held by spacers or separators II4, which may be butt-welded to the faces II3 of the members III, as indicated generally at II4a. This construction gives a generally lattice or ladder-like construction and structural member which is rigid in all its parts. The faces or portions II3 of the stanchion members III may be bowed inwardly along its length, as indicated at I I3a, to increase the stiffness and rigidity of the parallel vertical elements. In manufacture, a pair of members or vertical supporting elements III and appropriate spacers II4, may be suitably mounted, in spaced parallel relation, in a. jig and the whole electrically welded as by butt-welding, or they may be welded by hand, as by electric arc welding or gas welding, or brazed. It will, of course, be appreciated that other mechanical methods of securing the members together in fixed relationship, may be made use of. Among such methods may be indicated the slotting of the sections II3 of members III and the providing of members II4 with tongued ends adapted to fit in and engage the slots formed in sections II 3. Bolts or rivets may be used to effect the same results, but require greater time for assembly.

The lattice or composite structural studding H0 is provided with a base member or support 5 comprising an inverted channel member buttwelded or otherwise secured at itsbase to the bottom of the legs ormembers III of the member 0, as indicated generally at IIIa. This inverted channel member and support 5 in tum= is transversely disposed in another channel member or shoe II6, whichshoe is provided with or has a bottom piece I" with upstanding sides IIO provided with aligned apertures II9, over which the sections II5 are disposed to permit the passage of bolts I25 therethrough. The shoe 0 may be welded to the member II5 as indicated generally at 511. f

Considering the details of these constructions it will be noted that the vertical building supporting or wall members I I0 may be slidably en-. gaged by the socketed channel or base member I20, the foot member or shoe II 6 being sprung into place in the channel member and being locked therein, or prevented from being pulled out by the flanges I23 of thesides of the base channel or wall support I20.

The base channel I20, as previously noted, is provided with a plurality of aligned apertures I24, spaced suitable distances apart of the order of one inch more or less The vertical supporting units comprising the shoes IIB with the integrally associated studding I I0, are adapted to be moved along the base-supporting and locking channel I20 until the aligned apertures H9 in the shoe member are in alignment with a pair of apertures I24 in the base channel member. When a suitable and desired spacing between vertical supporting unit assemblies has been secured, the assemblies are permanently locked in position by inserting bolts I25 through the aligned apertures I24 and H9, and locking them in position by associated nuts of the bolt-andnut assemblies.

It will be noted that when the bolt assemblies are tightened up the sides I22 of the supporting and base channels I20 will be pulled inwardly of the wall and towards each other so that a positive gripping and locking of the shoes II6 of the vertical structural units IIO to the base channels I20 is effected. With this construction the studding assemblies IIO are permanently and positively secured and held in a desired alignment and spacing in building wall constructions.

To permit the joining and supporting of floor constructions 200 to the studding members I I0 at desired floor levels or heights, floor supporting structural members I and M01; are provided.

As indicated generally in Figs. 12 and 13, and

more in detail in Figs. 3, 4, 5, 6, '7, and 8, thecomposite hinge floor joint construction, which is a feature of novelty of the present invention, comprises a pair of yoke members I40 and 240 which are adaptedto be locked together by pin members I44, when floor trusses are used. Where floor units are used, modified connection members are used, as described hereinafter.

The yoke members I40 comprise parallel sides I with a base I42 therebetween and co-extensiv'e therewith, forming a generally U-shaped member with. the sides. At their ends the sides I4I terminate in hinge sections or portions I43 spaced from each other and adapted to receive other like hinge members 244 of the floor connection members, the two pairs of hinge members being held together and locked by .pins I44. The yoke or spaced floor supporting members I40 are permanently secured to the studding sections I II of the members H0 in any desired manner, as by means of-spot-welds, rivets, bolts and nuts, all as indicated generally at I45. The connection member or members 240 which, while forming a part of the floor supporting members,

form a component part of the composite hinge joint constructions herein, comprise a generally U-shaped member having sides 24I, a base portion 242, and end flanges 243 which are outturned and terminate in coiled, hinge sections 244. The members 240 will secure and hold plate members 2400 of floor supporting members generally. These plate members are permanently secured to the connection members 240 and held in place as by means of bolts, welds, or rivets, all'indicated generally at 240d.

For structural uses involving central wall constructions, the members I 40, as designated more particularly at M011 and shown in Fig. 13 are provided with aplurality of sets of looped hinge fingers I43. Where roof or gable joints are to be formed the composite studding members I I0 may be provided at their upper ends with connection plates or pivot members I50, which may be formed as a part of the yoke hinge members I40, or as separate plate members'heldin position by the members I40.

The floor constructions, designated generally by the numeral 200, may comprise one or more types of floor supporting truss members 220, or composite floor units 2I0 and 250, secured to the wall or studding members I I0, as hereinabove described, and provided with floor and ceiling panel members with or without associated structural plastic surfacings or coverings. Y

Referring now to Figs. 1, 3, 4, 5, 6, '7, and 8, novel structural members are disclosed for increasing the structural rigidity of the superstructure and maintaining a desired, accurate alignment and spacing of the several parts. Referring more particularly to these figures there is disclosed a spacing and bracing member 280 adapted to prevent weaving of the several parts of the superstructure without involving any fractional displacement from the perpendicular of the vertical structural members as well as displacement from the horizontal of the horizontal structural members. This member 280 comprises a generally flattened X-shaped member having arms 28I formed with flanges or edges 282 and terminating in hinge sockets 283 adapted toengage and mate with other hinges I43 and 214 hereinabove described. These members may be dieformed or forged to give a desired structural rigidity and toughness. The legs or sections 28I of the member 280 may be given any desired curvilinear configuration to secure a maximum of strength with a minimum of material. Thus, it

members 280 are spaced between and included in hinge-joint construction members and usually in such a manner that the hinge sections 283 thereof are included in and form a part of the jointhinge construction and are held in place by the pin members I44. In use, these members,ldue to their construction and arrangement, will not only prevent weaving of parts in the superstructure and other parts of the structure, but in addition where used at fioor levels with the hingejoint-plate members I40and spaced between parallel studs as shown more in detail in Figs. 7 and 8, they will afford a proper and positive alignment of the upper portion of the stud members and key them or lock them in a desired spaced relation, thus enhancing and assuring the stability of the panel members IGI without requiring the panel members to serve asstructural building supporting members. This permits the use of extra light weight panelling materials which are not required to be load-bearing or stress supporting. These panel members may be locked in place in the studs, as previously described; the bracing and supporting members 280 being placed thereover and locked in position buildings in which these members are incorporated and serve for this purpose as wind-bracing members. I i

Considering now the truss floor members indicated generally at 220 and shown more in detail in Figs. 3, 4, 5, and 6, the truss member comprises a top chord or rail 22I having a had 222 of generally rectangular shape and hollow. This member may be described as a generally tubular member of rectangular cross-section. On its bottom side the head member 222 is provided with continuous, spaced, depending web sections 223 terminating in outturned flanges 224, which are continued upwardly at 225 to form further stiffening and supporting flanges. The flange sections 225 are intumed at their top or upper edges, as indicated at 226, to provide stiffening edges" and retaining means for clip sections I66 of floor panels.

The bottom or tension member of the truss designated generally by the numeral 230, comprises a generally rectangular member having a central channel section 23I- terminating in lateral webs 232 which, are continued downwardly to form side web sections 233. The webs are provided with inturned stiffening edges or flanges 234 adapted to receive clipping sections I66 of floor panel members 2 I5. Truss rods 235 are preferably formed of tubing and are flattened at their ends, as indicated at 236. These flattened ends are inserted in the channels formed in the top and bottom truss members 23I and 230 and are secured in place in any desired manner, as by crimping, welding, brazing, or by means of bolts and nuts, and/or rivets. Normally the member 236 may be made of heavier material than the member 22I, due to the fact that the member 236, being the bottom truss member, is required to be a strengthening member essentially in tension, while the member 22I is exposed or subjected to compression.

The wall members or panellings and their means of adjustment to the verticalstructural supporting members or studs will now be described. The .wall members I60 may be composed of panels I6I of any suitable material such as metal lath in its various forms, including expanded metal lath with and without ribs. Pressed metal lath may also be used, as well as other metal sheathings including vitreous enamel sheets which are to serve as panels in and of themselves or as supporting members for plastic surfacings or preformed surfacings. Among the other surfacings which are comprehended within the purview of the present invention may be mentioned Bakelite and other condensation products when formed into panelling members; sheet .rock or asbestos-base materials, generally, in-

eluding cementitious aggregates of the same; gypsum and other products conformed into sheet or panel form. In addition to these general types of panelling materials, other materials,

. including compressed wood-base panellings with or without cement inclusions or ceramic materials. Included in the above materials will, of course, be comprehended materials such as gyp-" sum wall board, asbestos wall board, porcelain slabs and like ceramic products, wood fibre wall boards and paper-base boards with any desired surface finishes. Among other materials comprehended within the scope'of these disclosures are linoleum and cork-base sheetings or surfacings generally, ply-wood, oilcloth suitably finished and properly backed, as indicated above. The light-weight structural materials at present steel sheets or plates can be used where desired,

and may, of course, be formed with any suitable surfacefinish. Hardenable plastic materials when formed into sheets or panels and with any desired surface or simulated surfacings, may be used, as well as artificial and natural brick and stone materials, including thin tiles and the like, all being suitably secured to or supported on supporting members such as wire lath, or equiv-' alent materials. In the use of metal panellings of steel and steel compositions, aluminum and its alloys, copper and its alloys, and metals and their alloys generally, which are susceptible of forming into sheets and plates, may be made use of.

In the use of materials such as aluminum and copper and other metals, anodic surfacings or coatings may be formed and these oxidized coatings may be colored, as by dyeing, to cause any desired colorization and finish; but particularly, desired results are obtained with dyed aluminum oxidized surfacings in a variety of wall and panel colorings as the lakes formed are quite permanent and of good color and depth. Oxidized copper panellings may be anodically prepared to secure a variety of green colorings associated with natural weathering of such materials commonly known as verdigris. From the foregoing it will be appreciated that the wall and panel surfacings may be made of a wide variety of materials without departing from the spirit and disclosures of the present invention. This flexibility and use of material is enhanced by the fact that the panellings, as such, are riot required to be loadsupporting and to the further fact that they are rigidly and permanently secured in place in a special manner as will now be described.

The panel members I6I, above noted, are secured to the vertical and horizontal building supporting members in a new and improved fashion by securing members I62. The securing members I62 are elongated channels having a base or body portion I63, a side stiffening flange I64 on one side thereof, and an elongated flange I65 on the other side terminating in a folded-over spring edge I66. The section I65 and associated spring-clip edges I66 are so configured and arranged as to permit their insertion in the slots or apertures formed by the inturned stiffening flange II2 of the stud members III. The continuous members I62 may be secured to the panellings I6I of any desired material, as above indicated, in any suitable manner, as by welding, bolts, rivets, or equivalent securing means, all as indicated generally at I61. Where the nature of the materials used to form the members I6I permits, the sections I62 may be cast in place along the edges thereof.

It will be seen that when a pair of panels I 6| with their associated securing sections I62, are assembled in,a wall so that the sections I65 are introduced into the slotted studdings III and the spring edges I66 snapped in the same and prevented from being pulled out by the stiffening and holding flanges II2 of the stud sections II I, the panellings are permanently held in place.

The members I62, are preferably made of appreciable length to give an increased gripping and supporting function to the assembly. If desired the members I62 may be co-extensive in length with the panels with which they are associated or they may be formed of smaller sections or segments suitably secured to the panels along the' entire length. The panels I6I may be so assembled that their supporting members I62 have to abut like members in a wall or flooring joint,

to give a substantially hair-line joint I68, as

and should be co-extensive in length withthe flanges I65 of which they form a part, or they may be formed of separate cutout fingers to more readily permit the introduction of the members "place on the members I65. 7

The securing members are generally adapted for use with fioor and ceiling panels, as well as with the wall panels, care being taken in the several assemblies to use material of suitable auge and strength for the purpose desired.

It will now be appreciated that there have been provided improvements in building constructions,

including novel structural supporting members and associated parts; These improvements also include wall surfacings, comprising panel members adapted to be readily afiixed and secured to wall supporting members and with or without the use of structural cementitious plastics, such as concrete, plaster, stucco, and the like. In addition, novel fioor supporting systems have been disclosed which are adapted for general use in building systems, and are particularly adapted, in association with the novel wall structures herein, to form new building systems. The several structural members entering into the various building features are novel in design and function and provide, both alone and in the several combinations herein disclosed, adesirable structural strength with a minimum of weight of material. In addition, the improvements of the present invention are particularly adapted for use in the design and erection of so-called dry house constructions in which the several parts are preformed and assembled in place upon a finished structure, although, as already indicated, the several parts and improvements herein can be associated and erected into building structures with the aid of the usual structural cementitious plastic materials, and the like, to form the usual so-called wet system structures.

The terms and expressions which have been employed are used as terms of description and not of limitation, and there is no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described, or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
