PANEL John B. Anthony, -Berkeley, CalIf., assignor to Kaiser Engineers, Oakland, Calif., a corporation of California Application October 19, 1945, Serial No. 623,223 4 Claims. (Cl. ins-6.5)

This invention relates to building structures, and more particularly it relates to a panel for use in wall and roof structures of buildings.

Among the objects of the invention is the provision of a light weight, fire resistant panel which is economic and readily constructed. I

Another object of the invention is the provision of a wall and roof panel provided with means for interlocking and aligned attachment with adjacent units.

A further object is to provide a sectional wall or roof element adapted for external use, which in cooperation with a plurality of similar units, will provide an effective seal against the elements, as well. as against heat transfer.

According to the invention ther e is provided a panel for use in wall and roof structures comprising a metal sheet adapted for exterior use and a cementitious slab, said metal sheet having a corrugated portion extending along its length and said slab having means on at least two opposed edges for alignment with slabs in adjacent panels, and means for fastening said metal sheet to said slab in face to face relation. The invention also contemplates the use of a fibrous sheet for acoustical purposes and insulation, as well as ornamentation. In building structures a plurality of wall and roof panels in aligned relation are each fastened to the framework of These and other objects of the invention will be apparent from the specification and drawings, which illustrate a preferred embodiment of the invention.

In the drawings:

Figure 1 represents a section of a wall structure showing a plurality of assembled panels; and

Figure 2 represents an enlarged sectional view of one panel taken along line 2-2 of Figure 1;

Figure 3 is a view in perspective of a panel as-. sembly slab.

The panel assembly when erected generally comprises a corrugated metal sheet II and a cementitious slab I2 fastened to an exterior supporting framework I3 preferably composed of substantially parallel structural members by means of suitable bolts I I. The corrugated metal sheet II is adapted to serve as an exterior member and provide protection against the elements by virtue of its weather-proofing and waterproofing characteristics. The sheet II- may be of any desired thickness depending upon the unsupported length of the sheet and the extent to which it is needed for structural purposes. As shown in the drawings, it is adapted to rest against the slab I2 in face to face relation therewith and advantageously is of the same length as the slab. Its width may vary. and a single sheet may extend over the width of the slab or less, or over several slabs. The corrugated portions I5 run the length of the sheet II and are preferably rather large in cross-section so as to produce a, cellular-like panel of sheet II and slab I2 which contributes stiffness to the sheet and an ornamental appearance.

The slab-s I2 are preferably precast, reinforced, rectangular tile formed of cementitious material such as calcined gypsum. In the preferred form shown in the drawings, the slabs I2 are provided with tongue and groove means, respectively, on opposed edges for the purpose of providing alignment and interlocking with slabs in adjacent panels. Although, it is preferred to provide the tongue and groove arrangement I 6 at all edges of slab I2, satisfactory results may be obtained if they are on two opposed edges only. It is also useful to provide the edges ofslabs I2 with binders ll of metal or the like. The binders I'I give the slabs straight edges so that true joints may be had and erection facilitated. The binders also protect the edges of slab I2, particularly where tongue and groove means are used, against chipping, breaking and other damage. The binders I! also provide a surface to which interior finishing material may be attached. The binders I! are advantageously inserted in the mold when the slab I2 is cast so that the ends I8 of the binders may be anchored securely.

As stated previously, the cementitious material within the slab is preferably calcined gypsum, al though hydraulic cement, clay or other suitable materials may be used. In practice, it is desirable to reinforce the slab I2 so as to insure against failure in use. In the preferred embodiment wire mesh I9 is employed. Obviously mesh I9 or whatever other reinforcing means is used is cast integrally with the slab.

The slabs I2 and sheets II may be fastened together in any satisfactory fashion. In the embodiment shown in the drawings this is accomplished by providing bolts I4 which pass through holes 20 in slabs I2 and are in turn fastened to supporting framework I3 of the building structure. A recess 2| is provided in the face of slab I2 opposite sheet II where the bolt head may rest.

An inner lining 22 may also be used which is adapted to rest against the other face of slab I2. This inner lining 22 may be of any materials which would serve as additional insulation against heat transfer, give improved acoustic 3 effects. or ornamentation or the like. In the embodiment shown in the drawings the material 22 is fiber glass and is used for acoustic purposes. The fiber glass 12 is-held in place by metal screws 23 which extend into slab it. However, any suitable fastening means may be employed.

It is to be understood that the inner lining 22 is not an essential feature of the invention in all of its uses and, accordingly, may be dispensed with in certain cases.

The present invention has several advantages. It provides a panel assembly which is light in weight, of sturdy construction. has good insulating qualities, is adapted for exterior uses, and which may be readily erected with a minimum of time and expense.

The form of the invention shown herein represents the preferred embodiment thereof although variations may be made within the scope of the appended claims. For example, the corrugated portion of sheet II may be reinforced by filling it with gypsum or other cementitious material as shown at lia.

What is claimed is:

1; An exterior building wall including in combination a plurality of exposed and spaced apart parallel structural members. an interior panel assembly comprising a plurality of interlocking pre-cast slabs of fire resistant material lying ad- Jacent one another and supported by and spaced from said structural members, a longitudinally corrugated exterior sheet interposed between and contacting said structural members and said slabs of said panel assembly and common fastening means for securing said corrugated sheet to said structural members and to said slabs.

2. An exterior building wall including in combination a plurality of exterior and spaced apart parallel structural members, an interior panel assembly comprising a plurality of interlocking 9 pre-cast cementitious slabs lying adjacent one another and adapted to be rigidly supported by said structural members and spaced at a sub stantially equal distance therefrom, heat insulat ing and sound absorbing members fastened to the interior surface of said sla an exterior corrugated metallic sheet interposed between and contacting said structural members and said slabs of said panel assembly, and fastening means members for securing-said corrugated sheekto said structural members and to said panel assembly.

3. An exterior building wall including in combination a plurality of spaced apart and sub-- stantially parallel exposed support members, an interior panel assembly comprising a plurality of pre-cast interlocking rectangular cementitious slabs lying adjacent one another and supported by and spaced from said support members, a pinrality of exterior longitudinally corrugated sheets interposed between said support members and said slabs, the troughs between said sheet and said slabs being filled with cementitious material.

and fastening means common to both said slabs and said support members for securing said panel ligssembly and said sheets to the support memers.

4. A structure for a building comprising an exterior supporting framework, a plurality of in-' teriorly disposed slabs of cementitious material, said slabs having means on at least two opposed edges for interlocking engagement with adjacent slabs, protecting metallic binder members covering said edges and fixed to said slabs, an

exterior corrugated metallic sheet interposed between and in contact with said slabs and said framework and common fastening means for securing said corrugated sheet to said supporting framework and to said slabs.
