the type mentioned, the parts of which are oflow production cost; which are readily portable and readily, easily and .economically erectable by unskilled labor; which, when erected, afford a structure which is exceptionally strong and rigid, and which may readily, easily and completely be disassembled or salvaged without damage.
Other objects of the invention are: to provide interior wall and ceiling panel mounting means which are simple, of low cost, efcient for their purpose and which enable erection of the panels to be effected very expeditiously; to provide novel means for covering andnishing joints between adjacent panels, and to provide novel means for finishing wall openings such as doors, windows andthe like. I
With the foregoing and other objects in View, which will become more fully apparent as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and dened in the appended claims. l

Figure 14 is a vertical section through a window or door opening of the building.
In accordance with the invention there first is Figure 11 is a fragmentary perspective View of 5 provided a foundation A of concrete or other 15 suitable material, and then iiatly upon this foundation, are suitably fastened angle iron or equivalent elements I0 disposed to underlie the building walls to be erected. Next,upright angle iron or equivalent elements II are mounted at the corner points of the building to be erected, being bolted, riveted or otherwise secured at their lower ends to the angle iron or equivalent elementsy I0, and, in case vany given wall is to be of considerable length, other upright angle iron or equivalent elements I2 are mounted intermediate the related corner elements II, being also bolted, riveted or otherwise secured at their. lower ends to the related elements I0. y
At or near their upper ends,vthe upright corner elements II are connected together by angle iron or equivalent elements I3, and, in case upright intermediate elements I2 are employed between any two upright corner elements II, said elements I2 are connected, at or near their upper ends, to the related corner elements II by the velements I3.
The elements I0, Il, I2 and I3, generally speaking,l constitute the -building frame to the top ot which is suitably mounted a supporting structure,
fragmentarily illustrated in Fig. 1 and designated 40 generally as I 4, for a roof, also fragmentarily illustrated in Fig. 1 and designated as I5.
Following erection of the upright corner elements II and the intermediate upright elements I2,`if the latter are provided in any particular instance, related corner elements II and the intermediate elements I2, if provided, are connected together by Stringer elements I6 of p referably U-shape in cross section as shown. 'I'hese Stringer elements are horizontally disposed and are spaced suitable distances apart vertically and may be fastened to the corner elements II by bolts, rivets or in any other suitable manner.
Moreover. they may be of lengths to extend from corner element II to corner element II, in which event they may be intermediately notched to accommodate the intermediate upright elements I2 if the latter are provided, or, alternatively, they may be of lengths to extend from corner elements II to intermediate upright elements I2, in which case they may, of course, be bolted, riveted o1' otherwise suitably fastened at their inner ends to the intermediate elements I2. In either case, the closed sides of Said Stringer elements preferably are disposed inwardly and their upper and lower walls at their outer ends preferably are fianged upwardly and downwardly, respectively, to afford relatively wide surfaces against which to Secure the outer covering I1 of the building.
The outer covering I'I may be comprised by any suitable material and may be fastened to the Stringer elements I6 in any suitable manner. Preferably, however, said outer covering is comprised by corrugated sheet metal and is riveted to the flanged outer portions of the Stringer elements. The wall frames, including the Stringer elements I6, thus are reinforced and the Side walls of the building are rendered exceptionally Stiff and rigid.
Following erection of the building frame, roofing of the same, and application thereto of the outer covering I 1, insulating and finishing side and end wall and ceiling panels I8 are mounted interiorly of the building. In this connection and reverting to the frame structure, it will be observed that there are clamped between the foundation A and the angle iron or equivalent elements I0 the outer portions of retaining elements I9 for the bottom portions of the side and end wall panels I8. .These retaining elements I9 are formed from strips of sheet metal bent upon themselves to provide .their outer portions which are confined beneath the elements I, and have their marginal portions flanged upwardly in spaced relationship to each other to provide channels to accommodate the bottoms of the side and end wall panels I8.
Furthermore, there are riveted, bolted or otherwise suitably fastened to the stringer elements I6 at the corners of the building frame, vertically disposed sheet metal elements 2U to constitute abutments for the adjacent side edges of the side and end wall panels I8. The elements 20 extend diagonally at the corners of the building frame, are marginally secured to the Stringer elements I6 and have offset portions 2I (Figs. 4 and 12) providing the aforesaid abutments for the adjacent side edges of the side and end wall panels I8.
'Ihe panels I8 may be of any suitable width and thickness and may be formed from any suitable material. Preferably they are of lengths or heights to extend from the floor or foundation A of the building to the ceiling thereof.
In erecting the side and end wall panels the operator begins at one corner of the building. First, there is applied to the outer side edge of the first panel to be erected a double-channel strip 22 of substantially H shape in cross section as shown in Fig. 6. The strip 22 is stock material formed preferably from sheet metal bent upon itself to provide a web 23 and inner and outer flanges 24 and 25, respectively, extending in opposite directions from said web and providing the double channels mentioned. The outer side portion of the first panel to be erected is engaged in one of said channels and the other channel is left open. The panel then is inserted at its bottom into the channel of the retaining element I9 and at its inner side edge is engaged against the related offset or abutment portion 2I of the element 20. Holes then are punched through the exposed, inner fiange 24 of the strip 22 and through the stringer elements I6 and the strip 22 is fastened to said Stringer elements by screws 26 passed through the holes in the said flange 24 and threaded into the holes in the Stringer elements. A second strip 22 then is applied to one side edge of a second panel I 8, the second panel then is inserted at its bottom in the channel of the retaining strip I9 and the other Side edge of the second panel is inserted into the open or outwardly facing channel of the first mentioned strip 22. The second mentioned strip 22 then is fastened to the Stringer elements I6 in the same manner as the first mentioned strip 22. Thus, the first and the second side or end wall panels, as the case may be, are secured in place. The operation is repeated for successive side and end Wall panels until the side and end walls of the building are completely paneled. Finishing corner strips 21 of sheet metal as illustrated in Figs. l1 and l2 then are screw fastened to the elements 20 in overlying relationship to the adjacent side edge portions of the adjacent side and end wall panels I8 to retain said portions of said panels in place and, of course, to finish the side and end panel walls at the corners of the building.
Next, againstfthe inner faces of the side wall panels, near the tops thereof, are secured finishing elements 28 having inwardly opening channels 29 to accommodate Ithe side marginal portions of the ceiling panels I8. The elements 28 preferably are formed from sheet metal and are, or may be, duplicates, or substantially duplicates, of the channel elements I9. In any event, said elements 28 have vertical portions extending downwardly from their inwardly opening channel portions 29 to be fastened to the side wall panels by screws 30 which may extend into the upper Stringer elements I6 to assist in fastening the tops of the side wall panels.
Beginning at one side of the building, the ceiling panels I8 are mounted in generally the same way as the side and the end wall panels. That is to say, there is applied to the outer side edge of the first ceiling panel to be mounted, a doublechannel strip 3| as illustrated in detail in Fig, 8 0f the drawings. The strip 3l, which is of stock material, is composed of top and bottom, T-
shaped, sheet metal parts 32 and 33, respectively, of which the top part 32 is bent upon itself to provide an upwardly extending medial stifiening fiange 34 of channel form accommodating an upwardly extending medial flange 35 of the bottom part 33. The flange 35 is spot-welded or otherwise suitably Secured between the walls of the channel iiange 34. quite Stiff and rigid so that, although it may be supported only at its ends, it Serves effectively to hold against sagging the medial portions of the ceiling panels to which it is applied.
Should the ceiling Space from end wall to end wall of the building be of not greater length than the panels I8, the top parts 32 of the strips 3| are made suiiiciently longer than the bottom parts 33 of said strips to rest upon the tops of the top Stringer elements I6, as illustrated in Fig. 9 of the drawings. Usually, however, the ceiling space is equal in length to the lengths of two or more of the panels I8. In that caseI pairs of horizontally disposed angle iron elements 36 are mounted, as illustrated in Fig. 3 of the drawings, transversely of the building at the ceiling level and at points spaced panel lengths from the building end walls.
The strip SI thus is rendered If more than one pair of the angle iron elements 36 are employed, the pairs are, moreover, spaced panel lengths apart. Furthermore, if the strips 3| are to be used between adjacent pairs of angleiron elements 36, the ends of the upwardly extending stiffening flanges 34 of said strips are slotted, as indicated at 31 in Fig. I of the drawings, to receive the outwardly directed, bottom flanges of the angle iron elements 36. If, on the other hand, the strips 3| are to be used between an end wall' of the building and an adjacent angle-iron element 36, the top members 32 of the strips are made longer at one end than the bottom members 33 to rest upon the top of the end wall stringer element 6 at the ceiling level, and at their other ends the upwardly extending stiffening flanges of said strips are slotted as at 31.
Assuming that the rst ceiling panel to be mounted is to extend from an end wall of the building to an angle-iron element 36, one of the strips 3| as last described is applied to one side edge of the ceiling panel. The panel then is manipulated to engage its other side edge portion in the channel 29 of the member 28 at one side of the building; to interi-lt the slot 31 at the inner end of the strip 3| with the flange o f the angle-iron member 36, and to rest the projecting portion of the top element 32 of the strip 3| at the other end thereof upon the end wall Stringer element |6 at the ceiling level. The rst ceiling panel thus is mounted in position. To one side edge of a second ceiling panel a second strip 3| is applied and the second panel is manipulated to be mounted in place in the same manner as the rst panel, except that the other side edge of the second panel is engaged in the open or second channel of the rst applied strip 3|. This operation is repeated for succeeding ceiling panels entirely across the building, Working either from one side to the other or from both sides toward the center of the building, as may be desired.
After mounting of all of the ceiling panels, the exposed joints between the ends of adjacent of said panels are covered by finishing strips 38 which are secured in place by screws 39 passed through openings in said strips, upwardly between the spaced angle-iron elements 36 of the pairs of said elements and threaded into nut 40 engaged with the tops of the vertical flanges of said angle-iron elements 36.
Finally, the interior Wall structure is nished by applying sheet metal, angle strips 4| over theexposed upper ends of the end wall panels and the exposed adjacent ends ofthe ceiling panels, as illustrated in Figs. 3 and 9.
As will be apparent from the foregoing, the various elements comprising a building constructed in accordance with the invention, may be of stock construction; are readily portable and easily erecta'ble; afford a structure which is exceptionally strong and rigid and which may, should occasion arise, be readily dismantled or salvaged.
When a window opening is formed in a side or end of the building, the top and the bottom of the opening may appropriately be at the levels of a pair of the Stringer elements I6, and in that case sheet metal elements 42 and 43 may be engaged over the anges of said Stringer elements and with the exposed top and bottom edges of the outer covering at the window opening to 'nish said edges and to prevent rain, vsnow or the like,
in covering, finishing relation to the panel edges at the top and the bottom of the window opening at the inner side of the building, and other angle strips 46 may be fastened in covering, nishing relation to the panel edges at the sides of the window opening at the inner side of the building. On the other hand, at the outer side of the window opening, angle strips 41 may be fastened in covering, nishing relation to the edges of the outer covering |1 at the sides of the window opening, said strips 41 being secured, for example, beneath angle-iron sash stop elements 48 which, in turn, may be fastened by screws or in any other suitable manner to angleiron members 43 carried by the stringer elements I5 and which serve as closures fo-r the sides of the window opening.
A door opening may be finished in generally the same manner as a window or opening, except that a suitable sill may be employed in lieu of the bottom finishing members of a window opening.
The outer covering |1 may extend around the corners of the building. On the other hand, the
side and end wall outer coverings |1 may be sep- 2 arate from each other. In the latter event, sheet metal angle coverings for the exposed ends of the said side and end wall outer coverings |1 may be employed as illustrated in Fig. 2 of the drawings and may be fastened in place in any suitable manner.
For the sake of simplifying the foregoing description it has been assumed that the building is rectangular and is devoid of offsets and the like. However, it will be appreciated that, by means of the elements described, buildings with offsets or of otherwise irregular form, may be erected in accordance with the invention with substantiallyl the same facility as the conventional building shown.
It will further be appreciated that some, or all, of the Stringer elements may be disposed vertically if desired, particularly in partition walls, and that the Wall panel elements may, if desired, be disposed horizontally. instead of vertically; also, that the space between the outer covering and the paneled walls, or between double-paneled partition walls may, if desired, be filled with suitable insulating material.
Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.
