WALTER T/SCHUK CEC/L 0. KEYS AGENT United States Patent BUILDING PANEL HAVING TAPERED COUNTER- SUNK END PORTION AND METHOD OF ERECTING THE SAME Walter Tischuk, Richmond, Ind., and Cecil D. Keys,

Coraopolis, Pa., assignors to H. H. Robertson Company, Pittsburgh, Pa., a corporation of Pennsylvania Filed Dec. 4, 1968, Ser. No. 781,078 Int. Cl. E04b 1/54 US. Cl. 52394 8 Claims ABSTRACT OF THE DISCLOSURE A building panel having a leading end and a trailing end and provided with male and female lips on opposite longitudinal sides thereof permitting adjacent building panels to be erected in side-by-side interengaged relation. An improved countersunk end portion is formed at the leading end of the building panel. The countersunk end portion is tapered so as to present a diminishing width. The tapered countersunk end portion facilitates erection of two courses of the building panels in end-to-end overlapped relation.

BACKGROUND OF THE INVENTION Field of the invention This invention relates to building panels of the type which may be erected in side-by-side interengaged relation to form a wall structure, and more particularly to an improved countersunk end portion for such building panels and a method of erecting the same.

Description of the prior art Building panels having laterally extended male and female lips are known in the art. In brief, such prior art building panels include a main body of any desired profile, a longitudinal male lip on one side of the main body extending laterally outwardly thereof, and a female lip on the opposite side of the main body extending laterally therebeneath toward the male lip. A single course of such building panels may be erected in side-by-side interengaged relation. See US. Patent 3,300,934. In this instance, a U-shaped gasket may be fitted over and secured to the male lip. The gasket preferably extends the entire length of the male lip. During the assembly, the gasketed male lip of one panel is inserted into the female lip of an adjacent panel. The gasket fits snugly within the female lip and provides an effective seal at the joint between adjacent panels.

Such prior art panels also have been provided with countersunk ends whereby two or more courses of the panels may be erected as a wall structure. In this arrangement, each panel of one course is in end-to-end overlapped relation with the corresponding panel of a subjacent course. A first course of panels is erected in side-by-side interengaged relation. The first panel of the second course is erected in the normal manner. Thereafter, each successive panel of the second course must be moved laterally toward the previously erected second course panel to engage the male lip thereof in the female lip of the previously erected panel. That panel then must be lowered so that its lower end overlaps the countersunk end portion of the subjacent first course panel.

Where panels with the aforementioned gasketed male lips are used, great difiiculty is encountered when erecting the second course panels. The snug fit of the gasketed male lip in the adjacent female lip inhibits lowering of that panel into overlapped relation with the subjacent panel. Forced lowering of that panel may result in damage to the panel.

3,508,368 Patented Apr. 28, 1970 SUMMARY OF THE INVENTION The principal object of this invention is to provide a building panel having an improved countersunk end portion.

Another object of this invention is to provide an improved countersunk end portion for a building panel having a gasketed male lip, wherein the countersunk end portion facilitates erection of two or more courses of the building panels in side-to-side interengaged relation and in end-to-end overlapped relation.

A further object of this invention is to provide a method for erecting building panels having gasketed male lips.

The countersunk end portion of a building panel includes a main body portion, a female lip portion and a male lip portion corresponding with and adjoining respectively the main body, the female lip and the male lip of the remainder of the building panel. The countersunk end portion has surfaces which are olfset from the corresponding surfaces of the remainder of the building panel by at least one sheet thickness.

In accordance with the present invention, the main body portion has a trailing edge adjoining the main body of the building panel and a leading edge. The main body portion is tapered and has a diminishing width from the trailing edge to the leading edge. The overall arrangement is such that a female side of the trailing end of a second course panel may be engaged with the corresponding female side of the countersunk end portion of a subjacent panel and such that'the second course panel is positioned in diverging relation with the previously erected second course panel. Thereafter, that panel is pivoted about the point of engagement toward the previously erected second course panel to engage the gasketed male lip with the female lip. As a result, a side-to-side interengagement between that panel and the adjacent second course panel, and the desired end-to-end overlapped engagement between that second course panel and the subjacent panel are simultaneously achieved.

3 DESCRIPTION OF THE PREFERRED EMBODIMENT(S) FIGURE 1 illustrates a wall structure 10 being assembled from first and second courses 12, 14 of building panels 16a, 16b. Each of the courses 12, 14 includes a plurality of the building panels 16 erected in side-by-side interengaged relation. Each building panel 16 includes a leading end 18 provided with a tapered, countersunk end portion 20 of this invention, and a normal trailing end 22. The building panels 16a, 16b may be secured directly to the building structural framework of which only a girt 23 is illustrated. Alternatively, the building panel 16a, 16b may be assembled in wall structures of the double metal sheath-type.

FIGURES 2 and 4 illustrate a typical panel 16 formed from sheet material, such as steel, aluminum, plastics and the like. The panel 16 includes a main body 24 having a longitudinal centerline 26 and opposed side walls 28, 30. A female lip 32 provided on the side wall 28 extends laterally beneath the main body 24 toward the longitudinal centerline 26. A male lip 34 provided on the side wall 30 extends laterally away from the main body 24 and the female lip 32. A generally U-shaped gasket 36 (FIGURE 2) is fitted over and secured to the male lip 34 by any suitable means such as stapling. As shown in FIGURE 3, the gasket 36 fits snugly within female lip 32 and provides an effective weather tight seal.

The countersunk end portion 20' provided at the leading end 18 of the panel 16, includes a main body portion 38 having first and second side wall portions 40, 42, a female lip portion 44 and a male lip portion 46 corresponding with and adjoining respectively the main body 24, the side walls 28, 30, the female lip 32 and the male lip 34. As is conventional, the surfaces of the countersunk end portion 20 are offset from the corresponding surfaces of the remainder of the building panel by at least one sheet thickness. As a result of the countersinking operating, the width of the countersunk end portion 20 is reduced. The excess metal is taken up by a plurality of relief pads 47. Therefore, as shown in FIGURE 5, the countersunk end portion 20 of a first course building sheet 16a fits within the trailing end 22 of a second course building panel 16b, whereby the building panels 16a, 16b are assembled in end-to-end overlapping relation.

In accordance with the present invention, the main body portion 38 has a trailing edge 48 adjoining the main body 24 and a leading edge 50'. The main body portion 38 is tapered and has a diminishing width from the trailing edge 48 to the leading edge 50, as best shown in FIGURE 4. In particular, the first side wall portion 40 is parallel with the longitudinal center line 26, while the second side wall portion 42 is inclined relative to the longitudinal centerline 26 and converges toward the first side wall portion 40. Preferably, a side wall segment 52 connects the second side wall portion 42 to the remainder of the building panel. The side wall segment '52 is parallel with the first side wall portion 40. As shown in FIGURE 5, the side wall portion 40 and the side wall segment 52 are engaged, respectively, by the side walls 28, 30 of the second course panel 16b. The side wall portion 40 and the side wall segment '52 serve to align the second course building panel 16b with the first course building panel 16a.

Building panels of alternative configurations provided with a tapered countersunk end portion of this invention, are illustrated in FIGURES 6, 7 and 8. Corresponding numerals will be employed to identify corresponding parts heretofore described.

FIGURE 6 illustrates a building panel 54 having a countersunk end portion 56 including a trough-shaped main body portion 58. The main body portion 58 is provided with the inclined second side wall portion 42 which is connected to the remainder of the building panel by the side wall segment 52.

FIGURE 7 illustrates a building panel havin a countersunk end portion 62 including a generally Z-shaped main body portion 64. In this embodiment, the inclined second side wall portion 42 is positioned intermediate of the female lip portion 44 and the male lip portion 46. The side wall segment 52 connects the inclined second side wall portion 42 to the remainder of the building panel.

FIGURE 8 illustrates a building panel 66 having a countersunk end portion 68 including a main body portion 70 of ribbed profile. The main body portion 70 includes a first side wall portion 72 on one side thereof and an inclined second side wall portion 74 on the opposite side thereof. The second side wall portion 74 is connected to the remainder of the building panel by a side wall segment 76.

It will be appreciated that the countersunk end portions of the building panels 16, '56, 60* and 66 of FIGURES 2, 6, 7' and 8 are tapered and have a diminishing width from the trailing edge 48 to the leading edge 50.

Erection of the present building panel will now be described with reference to FIGURES 1 and 4. It is a convenient concept when describing the erection of the present building panels, to state that the trailing end 22 of the building panel 16 has a female side 78 (adjacent to the female lip 32) and a male side 80- (adjacent to the male lip 34), and corresponding female and male sides 82, 84 at the opposite end of the building panel 16 which adjoin the trailing-edge 48 of the countersunk. end portion 20.

In FIGURE 1, the initial position of a second course panel 16b is illustrated. The female side 78b of the panel 16b is engaged with the corresponding female side 82a of the subjacent course panel 16a. The panel 16b is laterally inclined and diverges from the previously erected panel 16b. The longitudinal centerline 26b of the panel 16b extends transversely of the longitudinal centerline 26a of the subjacent course panel 16a. The lower edge of the gasketed male lip 34b is engaged in the female lip (not visible) of the previously erected second course panel 16b. The engaged edges of the female sides 78b, 82a serve as a pivot point about which the second course panel 16b is pivoted in a counterclockwise direction. Such pivoting motion of the second course panel 16b is facilitated by the tapered countersunk end portion 20a of the subjacent course panel 16a. During counterclockwise pivoting of the second course panel 16b, the gasketed male lip 34b is readily received within the female lip of the previously erected second course panel 16b. It will also be appreciated that the pivoting motion of the second course panel 16b requires a minimal amount of movement of the gasketed male lip 34b longitudinally of the female lip of the previously erected second course panel 16b. This minimal longitudinal relative motion is easily accomplished without damage to either of the adjacent second course panels and without damage to the gasket.

It will be appreciated that pivoting the second course panel 16b about its line of engagement with the subjacent course panel 16a toward the previously erected second course panel 16b effects simultaneous engagement of the gasketed male lip 34 of the second coarse panel 16b with the female lip (not visible) of the previously erected second course panel 16b and overlapping of the trailing end 22b of the second course panel 16b with the countersunk end portion 20a of the subjacent course panel 16a.
