4 Claims.

Our invention relates to building construction and it has for its object the provision of a new and improved form and arrangement of parts in a structure made up of sheet steel or other suitable sheet material whereby an improved joint is provided between the adjacent panels making up the structure for use in a roof, a ceiling, a side wall, or other part of a, building. In

a structure of this type which is subject in many cases to almost daily temperature changes through fairly wide ranges, with the consequent substantial opening and closing of the joint by reason of contraction and expansioruwe have found it diiiicult to provide asatisfactory joint by the methods heretofore in use. It is the object of our invention to provide an improved arrangement by which a tight joint may be provided initially and by which expansion and contraction may be taken care of satisfactorily so as to enable the joint to remain permanently tight and effective.

It is one of the objects of our invention to provide a structure of this type which may be produced readily and cheaply upon a commercial basis and which can be assembled into its i'lnal operative form without diiiculty. It is another object of our invention to provide a structure of this type so arranged that the joint itself shall be protected as completely as possible from the weather.

It is another object of our invention to irnprove building construction of this type in sundry details hereinafter pointed out. 'I'he preferred means by which we have accomplished our several objects are illustrated in the accompanying drawing and are hereinafter specifically described. That which we believe to be new and desire to cover by Letters Patent is set forth in the claims.

In the drawing,-

Fig. 1 is a vertical sectional view through a building formed of steel panels and embodying our improved construction;

Fig. 2 is a horizontal sectional view taken substantially at the line 2 2 of Fig. 1; and

Fig. 3 is an enlarged detail view showing our improved joint strip removed from the cooperating parts.

Referring now to the several figures of the drawing in which corresponding parts are indicated by the same reference characters, I Il indlcates a foundation of any suitable type upon which is secured a base angle I I longitudinally thereof. As is clearly shown in Figs. 1 and 2, a plurality of panels I2, I3 and I4 are mounted upon the base angle II with their body portions in alignment with each other. In our improved arrangement (see Fig. 2), the body portion of each of the panels is bent along longitudinal lines at each side edge of lthe body portion to Cn A provide a, series of ange portions by which the panels are secured together in the desired cooperative relation. Such structure at oneside of the body portion of each panel comprises a flange portion I5 which is bent into acute angle relationship to the body portion,l a ange portion IB which is substantially parallel with the body portion, a flange portion I'I which is substantially perpendicular to the body portion and which extends backwardly some little distance beyond the body portion, and flange portions I8, I9 and 2l) each of which is bent at right angles to its adjacent ange portion so as to provide a box-like formation in rear of the body of the panel. At the opposite edge of each of the panels, a flange 2l in acute angle relation to the body portion is provided, joined to the next adjacent flange Vportion 22 parallel with the body portion, with flange portions 23, 24 and 25 bent each at right angles to the connected flange portion to form a box-like structure of a size to receive snugly the inside box-like arrangement of the adjacent panel. 'I'he arrangement is such that an undercut shoulder is provided adjacent to the edge of each of the panels at each side of the panel, with such undercut shoulders facingl away from the adjacent edge, the flange portions I1 and 23 being of such size as to cause the front face portions 22 and I6 of the undercut shoulder structures to stand in alignment with each other when the adjacent intertting boxes are secured in cooperative relation. In the arrangement shown, the intertting boxes of the panels are clamped firmly together by means of hook bolts 26 which engage the edge portions of the anges 20 and 25 so as to draw them tightly toward the vertical portion of the angle bar II. In the arrangement shown in Fig. 1, similar hook bolts 2'I are provided at the upper ends of the panels for securing the panels to the vertically disposed plate portion 28 of an angle bar 29 resting upon the upper ends of the panels.

For holding the panels I2, I3, and I4 in operative relation to each other so as to secure an effective closure of the joint between the panels, we have provided a clamping device in the form of a channel formed of sheet metal cut in the form of a strip and bent longitudinally to provide a body portion 30 and a series of flanges at each side. In the arrangement shown, a side ange portion 3| is provided at right angles to the body portion 30 at each side edge thereof, with a flange portion 32 formed with the ilange 3| and at right angles thereto, and with a iiangeV portion 33 formed with the flange 32 and standing in the same angular relation to said flange 32 as the angular relation between thefiange portion I5 and the body portion I 4 of the panel structure. After the panels have been secured in position as shown in Fig. 2, one of the channel members is secured in position in engagement with the undercut shoulder structures,such channel member being connected with the shoulders either by being slid longitudinally into engagement therewith from one end or by being sprung into position without such longitudinal movement. In the arrangement shown, the flanges 33 have face to face engagement with the flanges l5 and 2|, and the flanges 32 of the channel structure have face to face engagement with the body portions of the panels. In the arrangement as shown, the cut edge portions of the sheet metal forming the channel member are folded in so as to be protected by the channel. In the preferred arrangement, the channel is provided along each edge portion with a quantity of caulking material as indicated at 34 in Fig. 3.

With the parts connected in the arrangement as shown in Fig. 2, the panels are held securely in edge to edge engagement with each other by the channel members so as to keep the joint between the panels effectively closed for preventing the passage ,of rain therethrough. 'I'he arrangement is such that the panels are adapted to expand or contract as may be necessary from the normal arrangement as shown in the drawing, such expansion or contraction having no appreciable tendency to loosen the joint, since the metal is adapted to yield against its own resiliency for permitting the changed relative positions of the parts.

In the arrangement shown, the roof structure has the same arrangement as that shown and described in connection with the side wall. The showing upon the section line 2er-2a through the roof structure in Fig. 1 corresponds to Fig. 2 of the drawing, except that a frame bar 29 is connected with the panels in the roof in lieu of the angle bar Il as shown in said Fig. 2. I

While We prefer to employ the arrangement as shown in our drawing, it is to be understood that our invention is not to be restricted to the arrangement shown except so far as it may be so restricted in terms in the narrower claims. It will be understood that changes in the form and arrangement may well be made without departure from our invention.
