' PANEL CONSTRUCTION 7 Filed Jan. 8, 1947 2 SHEETS-SX-IEET 2 lillllll i IIINIIIIII? I j 1 Patented Nov. 27, 1951 UNITED PATENT OFFICE ,57 6,530 Be z O S R CTIO Lean, li-Meslal New O lea s L Anrl ee n em r t .7 a 7 865 2 E a ne- 1 The present invention relates to new and use! ful improvements in panel constructions for use as a building unit for the construction of walls, floors, ceilings, roofs, partitions, or for use otherwise in the building industry.

An important object of the invention is to provide a construction panel of this character composed of a pair of sheets of plywood or other relatively light inexpensive material and between which is glued or otherwise suitably secured a thin corrugated sheet of Wood, plastic, fiber board, metal or other suitable material to pro.- vide an insulation air space between the outer sheets of material.

A further object of the invention is to provide interlocking means between adjacent ends of the corrugated spacing and stiffening member to connect adjacent panels to each other and to provide reinforced sealing means for the interlockin ends. of the c rru ated m mbe r A further object of the invention is to provide a construction panel of this character which is strong and durable, inexpensive to manufacture, which provides a neat and attractive wall finish and which otherwise is well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference bein had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a fragmentary sectional view of a pair of panels in position for interlocking engagement with each other.

Figure 2 is a perspective view of one of the sealing fillers for the interlocking ends of the panels.

Figure 3 is a fragmentary sectional view showing a pair of the panels connected to each other and with the sealing fillers in position therein.

Figure 4 is a fragmentary elevational view of a pair of connected panels with parts broken away and shown in section.

Figure 5 is a sectional view of a cornerconstruction for the panels.

Figure 6 is a fragmentary side elevational view thereof.

Figure 7 is a fragmentary transverse sectional view of upper and lower connected panels.

Figure 8 is a fragmentary side elevational view of one of the panels, and

Figure 9 is a transverse sectional view of a modified panel construction.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numerals {land 6 designate a pair of panel units generally, each panel being constructed of a pair of sheets I and 5 of plywood or other suitable material and between each is positioned a corrugated spacing and stiffening member 9 which likewise may be constructed of plywood, pl astic, metal or other suitable material and cemented or otherwise secured to the inner surfaces of the sheets 1 and 8. A

The side edges of the corrugated member 9 pro-. ject outwardly from the adjacent edges of the sheets I and 8 to provide an interlocking hook I 0. adapted for interlocking engagement with the similar hooked end of an adjacent panel. The edges of the sheets I and 8 adjacent the hooked edges 16 of the corrugated member are offset from each other as indicated at H and [2 where: by the meeting edges of the strips 1 and 8 of adjacent panels will be offset from each other as shown in Figure 3 of the drawings.

The joint between the connected edges of the panels is reinforced by a filler strip 13 which is inserted through the interlocking ends of the corrugated members 9 and secured in position by nails or other suitable fasteners l4.

In providing a corner construction between a pair of the panels as shown at 15 and I6 in Figures 5 and 6 of the drawings, the panels are arranged with their longer ends positioned outermost and which brings the outwardl projecting edges of the reinforcing corrugated member I! with their valleys l8 facing inwardly of the corner and in which is inserted a reinforcing filler strip l9 conforming to the adjacent valley-s and secured therein by nails or other fasteners 20. An outer reinforcing strip 2| is positioned longitudinally against the outer surfaces of the meet ing ends of the reinforcing member I! with the side edges of the strip 2| inwardly of the outer surfaces of the panels as shown at 22 and secured in position by an angle finishing strip or molding 23.

As shown in Figure 7 of the drawings, one side edge of the corrugated reinforcing member 9 projects outwardly beyond the adjacent side edges of the outer sheets 1 and 8 of the panels, while at the opposite edge of the panels the reinforcing corrugated member 9 is positioned inwardly of the edges of the sheets I and 8 to thus provide an opening between the sheets I and 8 and in which the outwardly projecting edge of the corrugated member 9 of an adjacent panel is received.

The upper edge of corrugated member 9 is covered by a reinforcing strip 24.

In Figure 9, I have illustrated a modified panel construction which includes a Single fiat sheet 25 to one side of which is suitably secured a corrugated sheet 26. The overlapping edges of the corrugated sheets have fillers 21 in the valleys thereof to reinforce the joint and one or more fillers 28 may also be suitably secured in the valleys of the corrugations.

In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described, a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

I claim:

1. A wall construction comprising first and secnd panels, each of said panels having a pair of sheets of material including edges, the edges of the sheets of said first panel abutting the edges of the sheets of said second panel, a first corrugated member mounted between the sheets of said first panel and having a side portion projecting outwardly from the edges of the first panel, a second corrugated member mounted between the sheets of said second panel and including a side portion projecting outwardly from the edges of the second panel, the outwardly projecting side portions of said corrugated members being interlocked, and reinforcing ribs secured to the edges of said sheets for both panels and received in the interlocked side portions of said corrugated members, the edges of the sheets of each panel being oflfset from each other and said ribs also being ofiset from each other.

2. A wall construction comprising first and second panels, each of said panels having a pair of sheets of material including edges, the edges of the sheets of said first panel abutting the edges of the sheets of said second panel, a first corrugated member mounted between the sheets of said first panel and having a side portion projecting outwardly from the edges of the first panel, a second corrugated member mounted between the sheets of said second panel and including a side portion projecting outwardly from the edges of the second panel, the outwardly projecting side portions of said corrugated members being interlocked, a filler strip having a flat surface bearing against the inner faces of one sheet for both of said panels, means securing the filler strip to one sheet of each of said panels for retaining the edges of the sheets of said first panel in abutting relationship with the edges of the sheets of said second panel, said filler strip being receivedin the interlocked side portions of said corrugated members, the edges of the sheets of eachpanel being offset relative to each other.
