This invention relates to a iireproof construction and as shown more particularly in relation to a iireproof floorl and ceiling 'con'- struction, though adaptable for many other purposes.
The invention has forits object a construction at once reproof, light, and strong and of great rigidity-and durability as compared with some constructions heretofore used.
The invention embraces many novel features; and it consists of the matters hereinafter describe d,and more fully pointed out and defined in the appended claims.

desired form of reticulated material. netting Inay be constructed of rods or large In carrying out the invention and describing the same first in connection with a ioor and ceiling construction, A indicates I-beams of ordinary form supported in the usual manner in the Wall of abuilding on posts or in any desired manner. Across the tops of the V'1I-beams are laid carrying-rods B,` which are bent attheirends, forming hooks which embrace the upper oppositely-directed flange of adjacent I-beams. The I-beams throughout the entire Width and length of the building are so connected at suitable distances apart by meansv of said carrying-rods, upon which arelaid stri-ps or sheets of wire-netting, similar to that illustrated in Figs. 1 and 4, or other Said wires C, some of which lie across the carry- -ing-rods and act to distribute pressures from above. In the form of netting illustrated in Fig. 1 the netting is composed of longitudinal and transverse wires C and O2, both of which Vare bent at their point of crossing and are laced through washer-like disks C3, which lie over the transverse wires O2 and under the longitudinal wires C'. YIn the form illustrated in Fig. 4 disks C4 of metal are provided at the intersections of said wires, saiddisks having diametrically Opposite lugs c o, which are apertured and turned up and through which the longitudinal wires C pass over the transverse wires C2, as shownV in Figs. 6 and 7. When the metallic supporting-framework is thus prepared, the I-beams may be incased on their under sides with the usual board mold, and concrete may be lilled therein and tamped to fill the spaces between beams and. packed solidly around the carrying-rods B and into the meshes of the netting. When the concrete hardens, the molds may be removed and a l facing coat of cement or asphalt or other material spread on the under surfaoeor ceiling side of the concrete and the upper surface finished to form a floor.
In the form illustrated in Figs. 1 and 2 a plane ceiling is provided, supported on supplemental carrying-rods B2, which are bent upwardly at their ends which rest on the adjacent lower iianges of the I-bearns. In the form illustrated in Fig. 2 the carrying-rods B IOO or some of said carrying-rods are bent downwardly and beneath the carrying-rods B2 and act to support the same centrally. VVire-netting may be used, if preferred, in constructing the ceiling, the same being wired to the supplemental carrying-rods B2 or laid upon the same and the concrete filled in in the usual manner, leaving a space between the oor and ceiling, which space may be left as a dead-air space or may be filled with cinder or other poor conductor of heat, as preferred. The form illustrated in Fig. 3 is similar to that shown in Fig. 2`,witl1 the exception that the supplemental carrying-rods B2 are wired to the carrying-rods B by one or more strands of wire B', thereby rigidly supporting the ceiling from the floor above.
Obviously a construction embodyingr my in` vention may be employed in iireproofconstruction in many different ways,and in many instances, such as the construction of warehouses or the like, it may be neither necessary nor desirable to have a ceiling. In such cases the carrying-rod illustrated in Figs. 12 and 13 by B3 is hooked at its ends to engage over the I-beams, as before described, and bent downwardly or depressed intermediate of said I-beams, the netting is laid thereon, as before described, and the filling of concrete is applied. The ends of said carrying-rods are turned downwardly and outwardly, forming a support b for the part of the concrete which abuts against the web of the I-beams. Before applying the concrete a platform or mold of boards is supported between the I- beams a desired distance below the carryingrods. The concrete when applied is thereby given a plane under surface. When the concrete is set or hardened, the upper coating of asphalt or other material may be applied to form a smooth finish for the door or a tloorof any desired kind laid. In this construction the supplemental carrying-rods B4 and the clips D2 would of course be dispensed with.
Figs. 10 and 11 show another form of my ceiling and floor construction in which supplemental carrying-rods B4 are provided with hooked ends adapted to engage over the top of the I-beams and beneath the outer fianges at the top. Said rods are of sufficient length to extend downwardly along said I-beams and across between adjacent I-beams, as shown in Fig. 11. When said supplemental carrying-rods are in position, a strip of wire-netting C is placed thereon with its ends thereof extending upwardly beneath the carryingrods B2 against the upwardly-extending portions of the supplemental carrying-rods, as shown in Fig. 11, thereby forming a pocket to receive and support the concrete which is bedded thereon, as before described. Obviously in this form of my construction it would be difficult to secure the concrete in the spaces beneath the I-beams. For the purpose of rigidly securing the same thereto I provide clamps or clips, any of several forms of which may be used, that shown in Figs. 8 and 9 consisting of a band of strap metal slit longitudinally from the ends to near the center to form the tongues d2 d2, which are bent upwardly to form hooks to engage the bottom angesof the I-beams. The lateral portions of said straps are turned downwardly and outwardly to form the support d3 d3, the use of which is clearly illustrated in Fig. 18, in which the general construction is similar to that heretofore described for Fig. 12, with the exception that the end portions of the supplemental carrying-rods B4 adjacent to the webs of the I-beams are bent inwardly toward the AI-beams, thereby slightly arching the ends of said rods and causing the weight of the ceiling to be in part supported by a portion Xof the concrete extending upwardly adjacent to the web.
The construction illustrated in Figs. 12 and 13 is similar to that shown in Figs. 10 and 11, with the exception that means are shown for insulating the floor from changes of temperature and also a modified form of construction of a concrete clip d4, the construction of which is more clearly illustrated in Figs. 14 and 15, in which a piece of strap-iron is bent upwardly to form the hooks D2 D2, adapted to secure the clips to the bottom of the I-beams, and the tongues d4 d4 are bent downwardly and outwardly to engage the concrete. The concrete is secured in position, as before described, and when the same is set a plurality of strips of felt or other suitable material are laid one upon the other, covering the entire floor, and a layer of asbestos preparation is spread over the same. Above this are laid other strips of felt or the like, and on this may be secured the door, either of asphalt, wood, or other material, as desired. Obviously, if preferred, more than two layers of felt or other material may be employed, and each layer may be one or more thicknesses in depth.
Among the many purposes to which my invention is adaptable is a column construction, (illustrated in Figs. 16 and 17,) which may properly be considered a part of my invention. In this case a central column may be cast or constructed, hollow, as shown,of structural-iron plates and Z-irons and having laterally-projecting lianges at the corners. On said plates clips D2 are secured, similar to any of the clips hereinbefore described and having outwardly and laterally directed ends to engage the concrete or other illing material. Carrying-rods B5 are provided, the ends of which extend around and hook over the opposite flanges remote therefrom, as shown in Fig. 26, and the ends of which may be turned outwardly to form the supporting-hooks b5 b5 for the concrete or filling. About the extended ends of said clips and the hooks d5 d5 wire-netting or other reticulated material is tightly drawn,`as shown in Fig. 25, andthe concrete firmly bedded thereon in a manner similar to that already described, thus building up a column of uniform size and of great strength as compared with weight. The ex- IOO IIO
terior of said column may be finished with a coating of any desired kind-such as asphalt, plaster, or other desired materialto afford a finish.
Obviously my invention may be applied to many other purposes than herein described, and many details of construction may be modified without departing from the principle of my invention.
