This invention relates to improvements in metallic building construction and more particularly to the formation of sheets of metal into panel units having locking and stifiening units 5 from which wall sections may be assembled readily without the use of skilled labor.

Heretofore, metal structures have been built of both plain and corrugated metal sheets, such sheets being superimposed .upon a framework 10 or skeleton first erected for the purpose, saving, in one or two rare cases wherein sheets have been formed by convolutions into a framework or skeleton, which is then used to support inner and outer insulation and finished surfaces.

15 From a structural viewpoint no difilculty arises in erecting metal buildings of this general type, it being possible to' secure any desired strength or archltectural.form.' However, from a practical standpoint it is very expensive to erect 20 buildings of this nature for the reason that it requires a great amount of skilled field labor together with bolts, rivets, field welding and elaborate finishing operations to conceal crude jointsn Buildings of this general construction 5 are undesirable also' for the reason that they are seldom livable due to high heat conductivity of the metal and the rapidity with which heat flows from one surface to another through the many frame elements constituting through 30 metal" channels. Thus such structures as heretofore have been built are difficult to heat or keep cool regardless of the amount or. nature of the insulation used to separate the inner and outer walls. Sound is also transmitted through 35 the'framework to the sheet wall surfaces which actually amplify the noise which should be absorbed in properly designed walls. The heat insulating features of this invention are based on the principle that heat is reluctant L to enter or leave a surface. .For .this reason the lock-bars which act as joiners for adjacent wall sheets and spacers between inner and outer wall sheets are designed and assembled in such a manner that a large number of'surfaces' are 45 provided through which heat must pass before lock-bars for joining adjacent wall sheets and spacing inner and outer wall sheets, which are assembled to minimize heat transfer through 55 the walls.

A further object of the invention is to provide a plurality of surfaces through which heat must pass in order to be transferred from one side of the. wall to the other.

Another object of this invention is to provide a metal building construction which may be erected in the field without the use of skilled labor or extensive use of rivets, bolts and welding.

Still another object of this invention is to provide a house construction which may be readily erected in the field with a minimum of labor and which may be readily taken down and reassembled on another location.

Still another object of this invention is to provide a metal building construction having a decorative appearance which is pleasing to the eye.

These and other objects will appear from the following specification when taken with the ac companying drawings in which,

In the drawings, l indicates the inner and outer wall panels. The'edges of the wall panels and the inner and outer corner panels 2 and 3 are formed into. integral locking members or returnbends 4 comprising flanges I and webs I".. When set up to form a wall as shown in Fig. 1 the return bends are positioned adjacent to each other. Two adjacent locking members or return bends 4 form an anchor to which the lock-bar 4' isfltted by telescopically sliding its restricted U channels shown in Fig. 2, over the '50 anchor formed by the adjacent return bends l. The inner and outer wall panels are thus locked rigidly together. respectively, and the inner and outer panels are rigidly held in fixed spaced relation to form with the lock-bars l a series of closed box columns or girders possessing great strength with light weight.

The wall panels I may be of any desired material such as steel, alloy steel, copper, brass, aluminum or alloys and combinations of such metals. The panels may be given a decorative appearance by having a corrugated, perforated or design stamped surface. The decorative appearance may also be produced by cementing to the panel before bending a thin sheet of protective and decorative material. When this procedure is followed, the thin sheet is permanently locked to the panel I by the subsequent bending operation to form the return bends 4.

The lock-bar 4' is formed of two elongated strips substantially coextensive in length with the panels I, spot welded at their center portions 5,

and similarly bent at their sides to form facing channels 5. 'The facing channels on each side of the lock-bar 4' form the restricted U channels which telescopically engage the adjacent return bends 4. In order to insulate the wall panels from each other and from the lock-bars 4', the insulating sheaths I are provided. Each insulating sheath I is elongated to correspond to the lock-bar 4' and is telescopically fitted over adjacently disposed return bend portions 4 as shown by Fig. 4. They are formed of any suitable insulating material, fibrous or resinous, formed or extruded, but the use of thin metal forms dipped in insulation has been found most practical. The insulating material may be resinous, asphaltic or a rubber compound. For best results the insulating material should not soften seriously at 120 degrees Fahrenheit nor become brittle at sub-zero temperatures. The coating should be from 5 to 1*; of an inch thick to provide additional compensation for such slight variations as may occur informing the joining elements.

The depth of the return bends 4 is chosen to allow for expansion and contraction of walls with temperature changes, thereby avoiding bulging panels and permanently maintaining a smooth unbroken wall surface. It has been found that for the best design, considering all problems, that the flange I', should be substantially equal to one-half the length of the web I". It is essential that each of the return bends 4, the panels I, the lock-bars 4' and the sheaths I be alike respectively, and interchangeable. The forming operations for these parts may be accomplished on a good sheet metal brake or a press brake with suitable dies, but preferably on a rotary cold former.

With the wall panels above described any desired wall sections may be made. Fig. 1 illustrates straight wall sections, corners, partitions and intersecting walls. The individual panel sections I, 2 and 3 and the lock-bars 4 are made at the factory in standard sizes in their final form or in long stock lengths from which dealers cut the final lengths. In order to erect a house or other building it is merely necessary to ship the required number of parts to the erecting point and under competent supervision have ordinary labor assemble the parts into the form desired. In the event that later it should become necessary to take down the building all of the parts may be salvaged and reerected into a new structure elsewhere, with no loss or destruction of mate- With this improved construction the structure is, when initially erected, complete without the necessity of plastering, painting and other finishplaster.

ing operations, for the reason that the construction of the panel members adapts itself to permit final decorative or ornamental design before the panel members ever leave the factory. It is to be understood that. any suitable caps may be used to enclose open ends and any suitable means may be used to join floor and roof sections to wall sections, etc.

The walls when completely assembled may be left hollow or filled with an insulating material. In either case there is no metal to metal contact between the inner and outer wall panels. The lock-bars which connect the inner and outer walls are insulated from these walls by-the sheaths 'I. In addition to the insulating action of the sheaths I, heatis insulated by the action of the plurality of surfaces through which heat must pass to be transferred from one side of the wall to the other. Even though there be direct contact between any two bodies, the passage of heat through both of them is less rapid than the passsage of heat through a single body of equal size to the two contacting bodies.

Fig. 5 illustrates a modified form of lock-bar 50 and a wall construction particularly adaptable to roof and deck installations where there is likely to be standing water. It is also adaptable for exterior walls where a veneer of brick, stone or the like is to be used or where it is desired to attach laths for stucco. This construction also may be used for interior wall constructions where it is desired to attach wall board or laths for The inner wall panel I is the same as in the construction shown in Fig. l. The outer wall panel I is constructed with a modified form of return bend 26. The return bend 26 is integral with the outer panel I and may be termed an outer return bend as it has an external web and flange corresponding to the internal web I and flange I' shown in Fig. 1. In fabrication it is formed in advance of the usual internal return bend 4. Adjacent external return bends 26 are locked together by battens 24 which are elongated and are telescopically fitted to the external return bends similarly to the fitting of the lockbars 4' to the internal return bends 4. The batten 24 may be made with a skirt 25 or not, as desired.

The modified lock-bar 50 is similar in design to the lock-bar 4' and its function is the same. This form of lock-bar is particularly adaptable to constructions requiring walls of small thickness. The two restricted U portions are welded together at 60. The sheath I is the same as the sheath 1 used in Fig. 4. Fig. 6 illustrates a wall section according to the modification of Fig. 5 but with the sheaths I, the battens 24 and the lock-bars 50 removed. Fig. '7 is a separate view of the lockbar 50. The ceiling and deck constructions shown in Figures 5 and 6 may have their upper panels perforated for admitting concrete or light insulating concrete if it is desired to keep down tegral locking members or bends equivalent to the return bends 4. These locking members are made by. any suitable forming operation and preferably in the same manner as the return 3 bends 4. Referring particularly to Fig. 8 the integral locking members'comprise parallel offset flanges 8 and return webs 8'.

return webs 8 are side by side as shown in the When two wall I panels are adjacently disposedthe corresponding drawings. The adjacent panels are locked to gether by external lock-bars 9, which are U- shaped and fitted over the adjacent return webs 8. The external lock-bars 9 are concealed from view and the surface of the wall made smooth by flush battens 9'. The inner and outer panels are insulated from each other and held relatively to each other. by the insulating studs II], which may be of wood, fibre, asbestos, cement composition or other suitable material. Screws l0 through the parallel ofiset flanges are provided to attach the .panels to the studs.

In Fig. 9 the structure is somewhat similar 'to that in Fig. 8 with the exception that the return webs 8' are dispensed with and the parallel offset flanges 8" overlap. The inner and outer walls, respectively, are locked together by a bolt l6 passing through the overlapping parallel ofiset The bolt l6 at the'same time passes through a stud l0" similar to stud l0 and holds the inner and outer panels fixed with respect to each other. Through metal from one side of the wall to the other is avoided by 'means of the insulating washer I! made of fibre or any suitable material. Instead ofusing a through bolt the stud Ill may be solid and bolt replaced by a screw on each side.

- members I8.

In the form disclosed by Fig. '10, the locking members I8 are formed by single right angle bends of the panel sides. prised of two fiat strips Id of sheet metal con nected together at l9 as by spot welding and are sprung apart for telescoping over the locking members. The locking members l8 and the lockbars l8 are pre-punched' and'fiat nuts 20 fixed as by welding to one pair of the panel elements. The lock-bars [8 are coated with a plastic, or After telescoping the lock-bars [8 in place they are firmly clamped on the locking members l8 by the bolts 2|. The bolts 2| preferably are .enameled to prevent actual metal contact with the locking While the foregoing specification taken with the drawings describes specific embodiments, they are merely illustrative of the invention. Thus it'is within the scope of this invention to use the lock-bar of Fig. 2 with the wall sections of Fig. 5 or a wall section may be constructed having exterior return bends on both inner and outer panels. It is further within the contemplation of this invention that the structure be made up in miniature form for use as toys, and it is intended that I be limited only by the scope of the following claims.
