Patented Feb. 2, 1937 UNITE STATES PATENT OFFICE 29 Claims.

The present invention relates in general to building construction.

One of the objects of my invention is to produce an improved fire-proof construction for ceilings.

Another object is to provide a form of ceiling construction which can be manufactured in the form of panels and attached to the steel structure of a modern skyscraper type of building in a simple, inexpensive and expeditious manner.

Another object is to provide an improved ceiling construction, sound-proof in character.

Another object is to provide ceiling panels which may be manufactured in quantities and installed in a building directly on the steel construction thereof.

A still further object is to provide a method of attaching these panels to the steel beams of the building which will fire-proof the beams and prevent any warping arising from heat.

Still another object is to provide a ceiling panel of this type in which any desired nishing effect may be obtained, thereby avoiding a great amount of labor in plastering or interior decorating.

There are other objects of my invention which, together with the foregoing, will be described in the detailed specification that is to follow, taken in conjunction with the accompanying drawing forming a part thereof.

Referring now to the drawing:

Fig. l is a sectional elevation through a oor and ceiling of a building showing my improved ceiling construction; and

Fig. 2 is a fragmentary plan of the ceiling construction of Fig. l.

The modern type of building construction, and particularly oice building construction, requires the ceilings to be lathed and plastered in order to present a desirable appearance. This procedure is rather expensive, requires considerable time and labor and also necessitates considerable cost of maintenance in redecorating and repairing. The trend in modern building construction is to eliminate and reduce the cost as much as possible.

In my invention I employ' a panel of suitable width to span from beam to beam. in the steel construction of a building. The panel itself is constructed of tile or other suitable material with a light, sound-proof core, and having a nished outer surface. These panels are attached to the steel beams in a simple and expeditious manner and form the ceiling. This entirely eliminates any interior nish, reducing the first cost of the ceiling material and doing away with the labor of plasterers and painters.

In the drawing, like reference characters apply to similar parts throughout.

The reference characters l denote structural 5 beams lying between floors of a building. These beams are of any usual or well known type, usually of I-shape and latticed.

My improved ceiling panel 2 comprises a flat portion 3 with upstanding side portions 4, the 10 outer surface 5 of which is concave in shape, with a rounded edge portion 6. This portion of the ceiling panel 2 is composed of cement or any suitable material, and is cast in this shape and has bolts 1 embedded in the upstanding ilanges 4. 15 The interior or core 8 of the panel is composed of a light porous material which is preferably though not necessarily sound-deadening. This forms the complete ceiling block by union withA the outer cement portion 3. The outer surface of the flat portion 3 of the ceiling panel is usually finished by glazing or in any suitable manner and may have a panel 9 of cellotex cast or embedded therein for decorating and sound-deadening purposes. This acoustical panel may be omitted, 2 however, and the face 3 of the ceiling block 2 colored or given a plain white finish to simulate plaster, in any desired manner.

'Ihe width of the ceiling block 2 from. the extensions on the upstanding ang'e portions 4 is 30 such as just to go between the beams l of a ceiling with the rounded edge portions 6 in the middle of a steel beam. The ceiling block 2, on account of its core construction, is light, strong and sound-proof. 35

The ceiling is formed by placing the ceiling blocks 2 between the beams, passing a strap I0 through the lattice work of the structural beams l and uniting it by nuts I l to the bolts l of adjacent ceiling blocks. The bolts 'l may be embedded 40 in the ceiling block at the corners, or better at suitable distances along the edge to provide for proper rigidity.

It will be seen that adjacent ceiling blocks have their rounded edges 6 close together form- 45 ing a circular shaped trough between the blocks and enclosing the lower end of the beams. This trough is preferably filled with a cement which serves to unite adjacent ceiling blocks together and firmly attach them to the structural beams. A further result of this cementing is that the lower ends of the beams are covered so as to pre- Vent heat arising from a fire in the room, from causing buckling or distortion. The small depressions caused by the rounded edges of adjacent ceiling blocks coming together may be filled with plaster or preferably may be left in the original state to give a very pleasing paneled effect.

It will be seen that my improved ceiling block may be manufactured in large quantities at a relatively cheap price. Because of its light, sound-proof core, it is relatively easy to handle and not as subject to breakage as hollow tile. Furthermore, when the block is used in the ceiling, it is a relatively simplev matter to attach adjacent blocks together to form a complete ceiling, requiring more or less unskilled labor, and

because of its simplicity, the ceiling may be constructed in a relatively short time.

The ceiling, when formed, is a complete unit,

firmly attached to the steel structure of the building, absolutely sound-proof and highly pleasing in appearance. Furthermore, by the use of sound insulating panels any desired color effect may be obtained, or by the treatment of the tile on its lower or finished surface, any decorating effect desired may be secured. In addition, after installation, because it is permanently attached to the steel structure, there is no danger of breakageor cracking, and the maintenance from the standpoint of redecoration is relatively nil for the reason that it may be washed because of the nished or glazed condition of its under surface and present the same appearance as when it was originally installed.

The method of uniting adjacent blocks together, by which the lower end of the steel beam iscompletely protected from re, is highly advantageous as many building codes require that these beams be iire-proofed. This ordinarily introduced an additional cost or expense, which is entirely eliminated by my improved construction.

While I have described certain specific embodiments of my invention, I am aware that many changes, modifications and deviations may be made, and I desire to protect by Letters Patent all such changes, modifications and deviations as fall within the scope of the appended claims.
