This invention, generally stated, relates to a building construction vand has more particular relation to floor Aslabs as utilized in connection with abuilding construction.
is to provide'a iloor construction in which the door slabs of cementitious materialhave interlocked relation .one with another, considered both laterally and longitudinally of the flooring as a whole.
i A further object of the present invention is to provide a iioor structure of .theacharacter stated in which eachy iioor slab along its longitudinal edge is arranged to have interlocked relation with arcompanion slab by means of a knuckle-like connection of parts.
y A furtherobject of ,the present invention -is to provide a iloor structure of the character stated in which'each'slab is provided vwith,longitudinal meansv for interlocking with a companion slab A further object of the present invention is to provide a floor construction of the `character vstated in which means isprovidedwhereby in the `ease of re or VVexcessive heat the beams employed in connection with the channels are prevented from canting. l A further objectof thepresent invention is to provide a structure of Ythe character statedin which longitudinal plasterers channels are employed. between adjacentfloor slabs, which plasterers channels are relatively retained in proper position -`throughf.the instrumentality of'hooklike members coaadjacent withthe interlocking mediums-,as employedl in each floor slab. A still further object of the present invention 'is toprov'ide a floor structureof the character stated in which the plasterers channels'` and the hook yand eye connections are reinforced by means `of laterally extended cros's'wires. i A still furtherv object of.` the present invention `iste provide .aconstruction of the vcharacter stated in whichaunskilled mechanics may expeditiously 'assemblerailooring and a still further object of the present invention is to provide a lstructure ofthe character stated which i's--simple inv-con-v 'of the slabs horizontally, in `spaced relation, are

For the purpose of illustrating my invention I have shownin the accompanying drawings-one form thereof which is at present preferred by me, since the same has been found in practiceto give satisfactory and reliable results, although it is to be understood that the various instrumentalitiesl of 4which my invention' consists can v*bevariously arranged and organized and that my invention is not limitedy to the precise arrangement and organization of the instrumentalities as herein shown and described. n
vReferring to the drawings in detail, the reference numeral 10 designates `anelongated oor slab of cementitious material. and in practice a series of these slabs are positioned upon the tops of floor beams, usually I-beams, which are illustrated in the accompanying drawings. Each floor slab 10 longitudinally considered is provided with a series of ngers l1, betweenadjacent fingers there being provided spaces 12. The iin'-` gers 1l project outwardly upon each sideof a slab 10 in aplanefabove the base ofa slab'` but projected beyond'the boundary of thel slab base f line. rlilmbe'dded in and extended through-each v14 of a slab are tted over a pin of fingers 1l and slots 1210i adjacent slabs are iitted together to forman interlock of slabs laterally considered throughout a building structure. Thus, in laying a iioor it is not necessary to accurately space the floor beams because the interlock of slabs both longitudinally and laterally considered tends to maintain the slabs efciently` sustained even though a'ioor beamA is not immediately beneath adjacent ends of floor slabs. The reference numeral 16 designates plastererls channels, one of which is arranged between adjacent iloor slabs longitudinally considered from end to end of a building structure. These channels also serve Y-to provide a continuous interlock of slabs. Each channel iron rests upon the opposed meeting flanges 1'7 of the iioor slabs as best seen in Fig.. 9.` V'lhesechannel y means ofa wire coupling S bent substantially U-shaped' fashion and having the respective ends bent over as at 19 toengage over the tops of the channel'irons and the bottoms of the wire couplings 18 beingiextended below the hooks 14 of `interlock of parts is completed. By
the rods 13, see Fig. 9. Each finger 11.has depending `therefrom a pin20 which is the'terminus of a cross couplingv 21 of wire, best seen ingFig. '7. In positioning the plasterers channels 16 the same are .arranged so as to rest' upon the flanges'll ,and the slabs l0 and to be engaged by these pins 20. In order'to prevent canting of the oor beams` 33 in case of re or severe heat', I provide hook members,best seen in Fig. 11, which members are provided attheir upper ends with a hook-like portion 23 and at ltheirlower portions with a horizontally arranged part 24. In practice the hook-like part 23 isintroduced over a plasterers channel 16 land `the lower end of the device is positioned beneath the upper iiange of the viloor beam 22, as bestseen in Fig. 4 of the drawings, it being understood that the vertical portion,v 25f.of each ofi these hook-like 'devices `opposed relation to the pendant pins 20 and that theterminus of leach part 27 is iiush with the top of/a. floor slab 10 in order to facilitate ready transportationoff a floor slab. Inthe connection .it issto be :noted that the pendant pins 20 and the upwardly extended portions 2-1 of the couplings 21 cooperate to form vplasterers channels retaining imediums. Inv practice with the floor slabs `l0 in assembled position the knuckle-like joint connections are filled in With'cementitious material not shown in `the drawings, whereby the the above arrangementand construction of parts an interlock both longitudinally rand laterally considered is providedl throughout `the entire length of a The slabs may be assembled expeditiously by unskilled labor to provide an interlockjof slabs efliciently, thus doing away .witheither accurately kspacing oor beams` or manufacturing floorY slabs ,of such dimensions 'as irons 16 I tie'together by rnentitious material the opposed longitudinal edges of each slab being provided with spaced, laterally disposed fingers, the lingers of adjacent slabs being r`arranged to have interlocked connection one with another, and the lateral edges of which have interlocked, hook and eye connection one with another.
2. In a building structure of the character stated, rectangular floor slabs of pre-cast cementitious material, the opposed longitudinal edges of each slab being provided with spaced, laterallydisposed iingers, the fingers of adjacent slabs being arranged to have interlocked connection one with another, a channel iron arranged between adjacent longitudinal edges of said slabs, and laterally disposed ,mediums for connecting said channel irons in parallelism.
