REENFORGING FABRIC p Application filed October 6, 1928. `Serial No. 310,801.`

10 ing reenforcing mesh embedded therein, it

has always been necessary to construct expeni sive forms to back upor hold the concrete and then to mount the reenforcing mesh in s aced relation withthe form and apply the lflastic i i 115 concrete or cement whichfwas forced through and around the reenforcing fabric and against the form. After the plastic material was set the form was removed and theform side of the wall was dressed to remove any imperfec- By the use of mynovel combined form and reenforcing fabric and in accordance with my novel methodthe fabric is mounted 1n position and the concrete or other plastic mai 125 terial is applied directly to the opposite sides y thereof by pouring, cement gun methods, Aor by hand, as desired or necessary, and the fine mesh wire fabric backing sheet forms a porous support fof' the material Which will pro- `i ject thereto so as to bond and form a solid mass with the material applied to the other side, thus forming a solid composite structure with embedded reenforcing.

`In the drawings: Figure 1 is a vertical section through a wall constructed in accordance with my invention. Figure 2 is a transverse section taken on the line II--II of Figure l.

Figure 8 is a transverse section through a 49 typical roof or Hoor structure constructed in accordance with my invention.

Figure 4 is a plan view of a section of my novel combined form and reenforcing fabric. Figure 5 is a sectional view taken on the i i line V-V of Figure 4.

Figure 6 is a sectional View taken on the line VI-VI of Figure 4.

Figure 7 is a fragmentary plan of a portion of fabric showing the interstices of the back- 559 ing sheet filled or closed with a readily soli'llole substance'such as gelatin, glue, or the Figure 8 isa sectional view of the same, the section of filling material being exaggerated for the purpose of illustration.

Referring more particularlyto the drawings, the letter A designates the combined form and reenforcing fabric as a Whole which, in Figures l and 2, is shown bolted to angle struts 2 secured to columns 3 soas to support 60 a wall structure. i

In Figure 3 the fabric A-is shown secured across heavy floor girders 4 so as to support a concrete floor. The girders 4 are also adapty edto be encased in concrete or cement and for this purpose-a reenforcing fabric X is secured to the floor` supporting fabric A and extended along each side and the bottom of the girders 4. This fabric X is spaced vfrom the faces of the girder so as to permit the cement or concrete to key therebehind. The fabric X may be constructed lilrethe novel fabric of this invention or may be of ordinary construction, as desired, since the girders form a back to support the concrete or cement.

Referring now to* Figures 4 to 6, the reenforcing fabricA is composed of what I will term, for convenience of description, strand wires 5 andstay Wires 6, preferably uniformly spaced andwelded or otherwise secured together at their points of intersection.` A backing` sheet 7 of fine wire mesh fabric or cloth, such as is ordinarily `used, Vfor fly screens, is placed behind the wires 5 and 6 and held in position by means of weaving or lac- '25 ing wires 8 that are disposed mainly behind the backing sheet and are threaded therethrough and looped around the strand wires 6 at the points 9. l

The bends or loops 9 of the wires 8 are pref- 90 erably of such depth that the backing sheet 7 will be spaced from the plane of the mesh or fabric wires and 6 an .appreciable distance to permit the wires 5 and 6 tobe completely embedded in the cement, concrete or other plastic material. The depth of the loops 9 y may be varied when desired so as to properly position `the mesh in the plastic structure.

The backing sheet 7 is adapted to serve as a back or form for the concretecr other plastic material and is preferably provided with a filling or coating of a readily soluble substance 10, such as lue, gelatin, or the like, as shown in Figures and 8.

The filling 10 will form a temporary filler to close the interstices or mesh of the fabric sheet and will stop the plastic material first applied tothe fabric until the Water of the p astic mixture dissolves the filling. By the time the filling 10 is dissolved, the plastic material will have'partly set so that,while it may settle or be forced through the mesh of the backing sheet 7 to some degree, it Willnot run nor pass readily therethrough. All, or substantially all, of the filling material 10 will be dissolved ,by the water content of the plastic material so as to expose the plastic material and permit a second layer of plastic material applied to the other side of the fabric to join directly with the material previously applied onthe first side.

In using the novel fabric of the invention as shown 1n Figures 1 and 2, the plastic material'12is firstplacedonone side of the fabric and forced throughr the backing sheet and then on the other side, thus completely en-v closing the backing sheet 7 and reenforcing fabric and forming a unitary composite reenfelced Wall Without the use of separate wooden or other forms; The plastic material 1.2V ma `be applied in any of the several usual ways ut is preferably applied first to the side ofthe fabric containin the reenforcing mesh wires 5 and' 6, so as to orce the backing sheet 7 awal from said wires.

In ormingy the reenforced concrete floor constructiony of Figure 3, the reenforcing bars 14 are first mounted above the fabric A and the concrete floor 15 is poured directly onto the fabric backing sheet 7 without any other form. After the floor is poured,A the reenforcing fabric is covered with a layer of cement or other plastic materialV 16 to form a reenforced finished surface which contacts and bonds with the concrete lvthrough the mesh or interstices of the backing sheet forming a unitary com osite structure. Y

The beams which support the floor, are also enclosed' in a coatin yor covering of concrete or cement 17 at t esame time as the materialV 16 is applied, so as to form` a continuous structure.

e While I have described and illustrated certain specific embodiments of my invention, it. will be understood that I do not Wish to be y limited thereto since the invention is capable of being practiced in many modified forms without departing from the scope of the invention, as defined in the appended claims.

I claim:

1.` Acombinedform and reen-forcing fabric comprising reenforcing strand and stay Wires secured, together at theirpoints of intersection, a finely woven wire, mesh backing sheet disposed adjacent the one sidel of said Wires,

said backing sheet having the openings therein closed by a readily soluble compound so as to be dissolved by the plastic material applied to the fabric, and retaining means for said backing sheet, said retaining means being connected to said Wires and adapted to support said backing sheet in completely spaced relation theretoso as to permit complete embedment of said strand and stay Wires in the plastic material applied to said fabric.

2; A combined form andreenforcing fabric comprising reenforcing strand and stay Wires secured together at their points of intersection, a finely woven Wire mesh bacling sheet disposed adjacent one side of said Wires, said backing sheet having the openings therein closed by a readily removable com pound adapted to be removed by the plastic material applied to the fabric, and means for securing said backing sheet to said reenforcing Wires so as to form a unitary structure.

3; A combined form and reenforcing fabric comprising reenforcing strand and stay Wires secured together by Welding at all their points of intersection, a finely Woven Wire mesh backing sheet disposed adjacent one side of said Wires, said backing sheet having the openings therein closed by a readily removable compound adapted toV be removed by the plastic material appliedV to the fabric, and re taining means for said backing sheet, saidv retaining means consisting of Weaving wires disposed mainly to the rear of the backing sheet but extending therethrough and bent over said strand and stay Wires at a plurality of points, the bends of said Weaving Wires being of such depth that the backing sheet may have spaced relation to the strand and stay Wires.

In witness whereof, I have hereunto set my hand'.

' ARTHUR J. WHITE.
