2 Claims.

This invention relates to improvements in the method of construction of hollow concrete walls, floors and roofs, andmore particularly to the arrangement and utilization of my improved construction units or elements which are readily transported to aparticular building job, and with which any desired building or' construction may be easily and efficiently built.

- sheet metal which cooperate with sheets of metal lath or expanded metal which are spot welded An object of the invention is to provide a plurality of my improved inserts or forms made from thereto, and when properly positioned on a building jobfwill be filled with concrete and with suitablereinforcing rods or strips, to form the studs or joists, after which as many layers of plaster and concrete may be applied to the inner and outer sheets of metal lath which are spaced apart the distance of said inserts, thereby forming the inner and outer walls of the building, respectively.

Aiurtherobject of the invention is to provide improved sheet metal inserts or forms having sheets of metal lath or expanded metal spot welded thereto, which cooperate with suitable fastening means to support the inserts in the desired position and relation, whereby a double Walled construction may be built having air spaces between the walls.

A still further object of the invention is to provide an improvedbuilding construction in which my improved sheet metal inserts or forms will be used in conjunction with sheets of metal lath or expanded metal spot welded to the inserts, whereby the walls, floors and roof of a building may be constructed, all of which .are double walled, suitably reinforced, and forming air spaces between the walls, which are covered with plaster or cement, asdesired.

Other objects will appear as the description proceeds.

In the accompanying drawing which forms a part of my application,

Figure 1 is a transverse sectional view of a portion or corner of a wall formed in accordance with my invention;

Figure 2 is a vertical sectional view' of a floor showing my improved sheet metal inserts or forms in position;

Figure 3 is a transverse sectional view through a stud or joist, formed in accordance with my invention;

Figure 4 is a vertical sectional view taken through a wall and roof formed in accordance with my invention;

Figure 5 is a transverse sectional view through a wall showing a stud;

Figure 6 is a perspective view ofone of my improved sheet metal inserts or forms. and

Figure 7 is a side elevation of one of my improved locking clips or ties.

Like characters of reference are used throughout the following specification and the accompanying drawing to designate corresponding parts.

In carrying out my invention, I provide a plurality of sheet metal inserts or forms I which are formed at their opposite ends with laterally extending flanges 2, which in turn, have their outer or free extremities bent or angled inwardly as' at 3, and may be referred to as locking flanges. The inserts I cooperate with sheets of metal lath or expanded metal 4, said lath lying in contact with the flanges 2, and being spot welded at intervals to said flanges, as indicated at 5. The ends of the lath 4 are bent inwardly over the locking flanges 3, and extend a short distance there'beyo'nd, and serve to tie into the concrete when poured into the space between adjacent inserts.

As clearly illustrated in Figures 1 and 3, units will be formed including a pair of oppositely spaced sheets of metal lath 4, with cooperating connecting inserts l spot welded thereto adjacent their ends or sides. When the actual construction work is being done, these units will be placed in courses with adjacent ends of adjacent units abutting each other and being held in place by the locking clips or ties 6, which are slipped down over the adjacent locking flanges. Thus it will be seen that hollow stud forms will be provided at intervals in the wall construction, and suitable reinforcing rods or strips of steel 1 will be placed in these hollow forms, after which the concrete mix will be poured therein.

In Figure 1 of the drawing, I have shown a wall and corner, including two studs and a corner post in which a down spout ,8 may be positioned if desired. At any place in the construction, a partition may be formed by merely placing a unit against the metal lath of the wall, and tying the same thereto by suitable fastening wires or means 9, as indicated in Figure 1. The partition l0 may be of any desired thickness or extend at any angle from the wall. I

In Figure 2, I have illustrated my improved floor joist construction, which comprises the utilization of inserts ll having outwardly extending flanges I2 at their ends, which cooperate with sheets of metal lath or expanded metal l3. The lath I3 is nailing insert incorporated in a spot welded at intervals to the flanges l2, and is bent inwardly to tie into the concrete forming the joist, when poured. A clip 6 will tie the adjacent ends of the lath together at the lower end of the joist form, while tie wires [4 may be used at intervals to connect the upper or flared portions of the joist form. It will be understood that all inserts, tie wires, and clips will be permanently left in the construction, and each will add to the strength of the construction when the concrete mix is poured into the several forms.

In Figure 5 of the drawing, I have illustrated a stud, joist or rafter construction, which is formed similarly to the other constructions shown in Figures 1 and 3, except that I have included a suitably formed. nailing strip or insert l5, which may be either wood or metal, and of any desired shape and form. It will be understood that either the wood or metal insert 15 may be placed in any desired position, whereby flooring, siding or roofing may be nailed thereto.

In Figure 3, I have shown a sectional view through a rafter l6, which is formed approximately like a stud, and as shown supports a suitable roof material I! and a plaster ceiling [8.

In Figure 4, I have illustrated how the end of a roofing rafter is supported on and tied to the side wall of the building. A metal lath form I!) willbe supported within the upper end of the wall 20, and will be filled with concrete mix and reinforcing rods 2|, to form a substantial plate upon which the roof proper will be seated. The

reinforcing rods I inserted in the studs will ex- .bers having reversely directed flanges on the flanges thereof, the channel members being held in substantially abutting relationship by clips fitting over the inwardly directed flanges, and wall reinforcing members of wire mesh clamped between the channel members at the ends thereof, reinforced concrete fillings for the openings between the channel members and the plastic facings on the reinforcing members at the wall faces.

2. A building wall comprising spaced supporting elements each comprising two channel members having reversely directed flanges on the flanges thereof, the channel members being held in substantially abutting relationship by clips fitting over the inwardly-directed flanges, Wall reinforcing members of wiremesh clamped between the channel members at the ends thereof, reinforced concrete fillings forthe openings between .the channel members and the plasticfacings on the reinforcing members-atthe wall faces, a connection between the Wall and an angularly disposed partition comprising wall reinforcing members tied to the like members of the first memtioned wall and spaced fromeach other by a single channel having reversely bent flanges and tied to the two reinforcing members of the partition.
