Description
Nov. 19, 1935. s. SHAW 2,021,434
FLOOR CONSTRUCTION Filed June 12, 1933 INVENTOR ATTORN EY Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE 7 Claims.
This invention relates to a floor construction.
It is an object of the invention to provide a floor construction having spaced steel members or beams in themselves of sufiicient strength to carry the floor load. Spanning between these members are precast floor blocks. The length of each block is somewhat less than the space between said members, resulting in a space between the ends of the block and the members. The ends of the blocks are formed with depressions or grooves to form a key or interlock when the spaces between the ends of the blocks and the steel sup-porting member are filled with concrete, lime plaster of Paris, or other material which solidifies from a plastic or fluid state. The vertical reaction of the blocks instead of being transmitted directly to the steel supports, as heretofore, is transmitted through the filling material. I My construction is particularly advantageous in that it can be used where the floor supports are relatively far apart.
Other objects and advantages will become apparent upon further study of the description and drawing, in which:
1 is a perspective View of a portion of a liter, and
Fig. 2 is a perspective view to an enlarged scale of a portion of the floor at a support.
The supports consist of steel floor beams 3 which are preferably rolled sections, or they may be of a built up type as shown at t. The sup ports have suflicient strength in themselves to carry the floor load. Other types of steel supports having suflicient strength in themselves may be used.
Spanning between the steel supports are precast blocks 5. These blocks can be made of various materials, preferably masonry, such as concrete, terra cotta or gypsum. They may be reinforced as with steel rods 8 and I2. They may be solid, or hollow as shown. Blocks 5 are shorter than the distance between the supporting members, giving rise to a space into which the filler 6 can be poured. The ends of blocks 5 are undercut as at I to give the filler a keying action, for keying a block to the support when the filler sets or hardens. The filler can be of concrete, cement or lime mortar, gypsum or other material which hardens from a fluid condition.
My preferred form of support is an I beam section whether rolled solid as at 3 or built up as at 4. The undercut or groove 1 is so formed as to leave a space around the bottom flange of the beam for the filler to pass by, the shape of the undercut being such that only a minimum of filler 6 will be: required.
Where hollow blocks are used, they are provided with diagonal webs 9, to give the blocks strength as an arch or truss. The block will act 5 as a truss if the material of the lower chord has sufficient tensile strength in itself or is reinforced with rods l2. A vertical web or hanger Hi is also provided to reduce the span of the lower chord l I. Lower chord I I if properly rubbed or painted 10 can act directly as a ceiling, without the addition of plaster, it being noted that the bottom of said chord comes below the bottom of the supporting beam. Hanger Hi joins upper chord l5 between the upper ends of the oppositely in- 5 clined diagonals 9.
In systems. heretofore proposed, the supports are spaced relatively close together, but with my system relatively wide spacing of the supporting beams may be used.
' In setting up the floor after the steel beams have been erected, the blocks 5 are set on forms l3 which may be supported from below by members M (as shown) or by other suitable framing or they may be hung from beams 3. Filler 6 is then poured into thespace above form [3 and between the end of blocks 5 and floor beam 3. When the filler ii has set or hardened, blocks 5 are keyed to the floor beams.
While my construction has been described in connection with. a floor, I wish it to be understood that the claims are intended to cover such a construction when used as a roof, platform or deck or in other similar situations.
