WALL SUPPORT FOR FLOOR SYSTEHS Filed Aug. 2, 1938 crete floor slabs or Patented Apr. 15, 1941 UNITED STATES PATENT OFFICE WALL sum-oar FOR noon SYSTEMS Morris Berma-n, New York, N. Y. ApplicationAugust 2,1938, Serial naezasn eams. (01. 72-108 1 I This invention relates to building construction, and particularly to the connection between consteel floor girders to a mason ry wall.

Itis well known that when a beam or girder is framed into a masonrywall at one or both ends, normal stresses on the beam'result in' upward deflection of the ends of said beam or girder. Such deflection tends to overturn or crack the masonry wall into which the beam is framed. Thisis also true in cases where the floor or roof slab is cast of concrete and is framed directly into the masonry walls.

My invention therefore contemplates the provision of such a connection between the slab, beam or girder to the masonry wall, that the ends of the slab, girder or beam are free to deflect upwardly without over-stressing the wall and particularly without any danger of the walls being cracked or overturned.

My invention further contemplates the provision of means for carrying the stresses in that part of the wall above the floor past the floor to the part of the wall below the floor whereby said means is stressed no further when the floor or floor parts are upwardly deflected at their ends.

My invention further contemplates'the provision of spaces or recesses in the ends of the floor in which spaces or recesses are arranged, means for transmitting the weight of the wall above the floor to the wall part below the floor independently of the floor ends.

The various objects of my invention will be clear from the description which follows and from the drawing, in which,

Fig. 1 is a horizontal section and fragmentary plan view of a concrete floor slab and asupporting masonry wall therefor to which my invention has been applied.

Fig. 2 is a vertical section and partial elevation of the same.

Fig. 3 is a similar view of the means for bridging the space above a floor beam or a concrete slab resting on a. wall.

In the practical embodiment of my invention the floor slab l which is here shown as being of concrete is suitably reinforced as by the reinforcing rods l3. Said slab is cast on the masonry wall 5 after said wall has been built to the required height. The wall 5 may be of brick, terra cotta, concrete block or any of the usual forms of construction, faced if desired or veneered by the brick or other facing 4.

In casting the slab I said slab is made discontinuous at its ends by the formation therein of a seriesof spaced and inwardly directed'recesses as I4 extending from the outermost edge l5 of the slab inwardly for a distance substantially equal' to the thickness of the wall 5. The shape of the recesses I4 is immaterial but I prefer to make them substantially rectangular for convenience. The recesses 14 produce a seriesof spaced projections or tongues IS on the ends of the slab, said tongues resting on and being-supported by the wall 5.

Means in the nature of arches or the'like' are provided in the recesses M to bridge the space above and at both sides of the tongues l6. As shown in Figs. 1 and 2 said means takes the form of compression members such as upright piers, struts or columns 3 or columns each of somewhat greater height than the thickness of the floor slab, the space between said compression members being spanned by suitable horizontal members such as the blocks 8 resting on the short piers or columns. The

members

3 and 8 may be made of brick, tile or other suitable floor or wall material and are set into place either before the casting of the floor slab l or after said slab has been cast as may be found convenient or desirable.

It should be understood that the materials and shapes here shown are for purposes of illustration only, and any other building materials or shapes may be substituted for those shown.

In the construction of the building th wall 5 is carried up to the level of the bottom of the floor slab or to the level of the under face of the beam or girder Hi. In the case where girders are used in the floor system, the under surfaces of said girders rest at their ends on the adjacent top surface of the wall 5, the wall having an empty or hollow space therein around the end of the girder so as to leave said end free of the wall except at 'its under surface. Then the slab is cast or floor system or beams set. The slab is cast so that the tongues l6 fit loosely between the struts 3. Such loose fit may be accomplished by oiling the struts 3 before pouring the concrete for the slab, or by setting the struts 3 in place in an empty space therefor left in the wall, after the slab is poured. Space between the tongues l6 and. the struts 3 may be filled with asphalt waterproofing material. Blocks 8 are then spanned across the struts 3 and the arch I laid over the blocks 8. The exact form of construction would to a large extent be determined by the loads to be carried by the wall, slab, beam or girder. The type and method of construction here indicated are for purpose of general illustration of the invention. Thus, the struts 3 might be staggered on alternate floors so as not to be directly above one another, bearing plates may be placed under the beams or struts, and the beams 0r slabs may be anchored, preferably, to the wall. Thin anchor strips I I may be inserted between the floor system and the wall in the space between the floor and arch l. The reenforcement l2 transmits slab loads between the tongues Hi. In the above construction it will be noted that upward deflection of the floor system at the wall will take place without overturning the wall, as a free space is provided between such system and the arch or spanner 9.

I claim:

1. In a building construction, a masonry wall,

mitting said stress to the wall portion below the slab.

2. In combination, a masonry wall, a floor having spaced slots therein, those portions of the floor between the slots resting on the wall and the remaining part of the floor being free of the wall, said wall having a free space therein above each of said floor portions, and means for carrying the weight of that part of the wall above said fioor portions to that part of the wall below the floor.

3. The combination with a wall, of a floor having spaced end projections, said wall having pockets formed therein for the reception of said projections, the height of each pocket being greater than that of the projection received thereby whereby the projection is capable of upward deflection within the pocket, and a supporting member for each of those parts of the Wall above the respective pockets, said member having a horizontal part extending across the pocket and having vertically arranged parts resting on that part of the wall below the floor and thereby transferring the weight of that part of the wall above the pocket to that part of the wall below the floor.

4. In a building construction, a masonry wall having spaced pockets therein, floor members set into said pockets and of less height than that of the pockets, said members resting on the bottom surfaces of said pockets, said floor members being arranged in horizontal spaced relation, and means for supporting those portions of the wall above said floor members comprising a horizontal member spanning each of the pockets and vertical members supporting the horizontal member and resting on that part of the wall below the floor members.
