Specification of Letters Patent. Patented 0V. 192( To all whom iii-may concerns Be it known that I, PEREZ M. STEWART, a citizen of the United, States, residing in county, and State of New ork, have-1nvented an Improvement in fReinforced' Building Construction, of which the following description, %in connectionwith the ac- .as embodied in a floor thereof.
1 companying drawings, is a specification, like characters-0n thedrawings representing like parts. 7 V
This invention relates to a reinforced building construction and isherein shown The invention has for its object to provide a construction" which is simple, efiicient and inexpensive,.whereby a floor slabrmay be obtained in which the metal reinforcement is secured in fixed position at a predetermined. distanceabove'the bottom or lower surface of the said slab, seats to obtaina predetermined thickness of the slab below the reinforcement to protect the same from .z'fire, and whereby a fiooruslab ofincreased carrying capacity may be obtained. 7
The invention is particularly applicable to floor slabs employing a continuous length of wire mesh as the reinforcement for the concrete, gypsum or" like plastic material.
-To'this end the wire mesh, which extends over the beams forming thebays in the floor construction, is supported at or near the centers of adjacent bays byisuitable devices,
7 hereinafter termed chairs, .which are made of a predetermined height, according'to the thickness of the layer of plastlc mater1al it is desired to have below the reinforcing wire mesh at the lowest point of the latter, and said mesh preferably haslaid upon it above the chair ineach bay, a device prefer-' ably a metal rod, which extends transversely of-the mesh and is fastened to the chair preferably by a wire as will be described.
The chairs are fastened to the form which closes the bottoms of the. bays'and upon whichthe concrete or other plastic material is laid or dumped as now commonly practisedin making monolithic floors, andthe bottoms of said chairs are substantially I flush with the bottom of'the slab.
a The wiremesh is firmly secured in definite relation to the forml andlto the bottom f of the concrete slab.
-These}andwother features of this inven-' plastic material thereon.
Y tion will be pointed out in the claims the end of this specification. 1 F igure 1 .sa section of a sufficient per-- tionjof a fioor con'struction embodyin' this invention 'to'enableit to beunderstoo Fig. 2, a plan of a portion ofthe-floor' shown 1nF1g. 1,. and F ig. 3,1an enlarged detail of the chair preferred. byme.
Referring to the 'dra'wingfa represents the beams of a monolithic floor 'slab b of concrete, gypsum or like plastic material; and 0 the metal reinforcement for said slab, preferably wire mesh, which is. usually made of sufficient length to extend from'wall to wall of the buildiiig and to pass over the beams and d1p1 down into the bays between saidbeams. The floor as thus far constructed 1s such as 1s now largely used in rein forced bu1ld1ng construction, and the present invention has for. its object to provide a v simple and efficient means-for anchoring the wire mesh within thebays formed by the beams a, so that the said mesh may be permanently located within the slab b at a predetermined distance above the bottom of the slab, and therebycomply with the require- '80, ments of the authorities for adequate pro- To this end, the wire mesh c is supported within the'bays'between the beams a by suitabledevices or chairs 0?, which may be made as herein shown (see Fig. 3) and which consists of a channel-shaped meta-l structure provided with sides 10, preferably"convergmg, a top 12 connecting said sides, and feet i l3-extended fro1nthe bottom of said sides and provided with suitable holes for the passage of nails or other fastening devices 14:, by which the chairs can be firmly Se 7 cured to thewood or other form 15, such as now commonly used in making concrete "floors. The chairs (Z are preferably located at or'near the center-ofthe baysand are fastened tothe wood form 15 before'the is poured or dumped Each bay 'may be provided with single I long chair or if desired with ai -plurality "of" shorterchairsarranged in alinement," and it in the present'instance three chairs spaced apart in each bay are'shown in Fig. 2.
' After the chairs have been secured-to the form 1'5,the wire mesh-* 'isflaid in place after the manner represented. in Fig. 1', and
may be secured to thechairs dor as ispreferred, a metal rod 16 is l'a'idu'pon the mesh so as to be supported by the chairs in each bay and. thus extend". transversely of the mesh as clearly representedin Figsql and 2, and the rod 16 and wire mesh 0 are then 17 which is passed through holes 18 .in the sides ofthe chair and through the mesh-and over thefirod 16 and hasits ends twisted or a I tied together afterthe manner; represented I, ginFigr3.
In practice,the tiewire 1'? may be' aflixed to the chair by partiallyjor wholly filling the latter with plastic material 20 in the factory,'which material when set firmly locks the wire to the chairand bonds wlth the plastic material of'the floor slab I), thus firmly retaining the chair in permanent position' withinthe floor slab with its bottom portion substantially flush-with the bottom of the slab, afterthe wood form'15has been removed and the. nails 14' cutoff flush with the bottom oftheslab.
After the meshfc and the rods 16 have been anchored to the chairs in the bays, the
wire mesh can be placed under tension, and
the, concrete} or plastic material 'is' poured or dumpedinto the bays to form the floor.
slab b in the'usual manner.
, From theabove description, it will be seen, Icy-reference to Fig.v 1, that the wire mesh. 0 is anchored and deflected at the ecu-- ter of each bay and is retained at a definite or predetermined position aboveathe bottom of the slab, withtheresult that it is pro-- {tected against fireby a definite or predeter- 'mined amount ofplastic' material of substantial thickness, and further by thus loeating themesh in the-slab; the carrying capacity of the latteris increased, which 'enables rgypsum and like materialihaving minimum compressive value ;tobe employed with safety. The chairs (Z have a substantial surface area with which the plastic ma-- terial contacts, so that when embedded in the-plasticmaterial, they successfully resist h -material and-thus serve to keepthe wire,
