PATENTED AUG] 7 1971 11v VENTURE. W/LL/AM 6. HoLLEM/F 4 J OHN .5. 1:55:21 11 BRACKET FOR ASSEMBLING CONCRETE FORMS SUMMARY OF THE INVENTION A tie rod bracket for assembling forms for constructing sloping slab-type concrete foundations having one stepped surface comprising wire rods welded together to provide horizontally and vertically disposed tie rods adapted to be imbedded in the concrete, with the tie rods providing protruding extremities which are either forcibly projected into the inclined soffit or projected through the riser form and adapted to receive a waler support and waler by which the assembled form is reinforced and aligned prior to pouring of the concrete therein.

GENERAL DESCRIPTION The invention will be best understood by reference to the accompanying drawings showing the preferred form of embodiment, and in which:

FIG. 1 is a fragmentary detailed side elevational view of an assembled bracket and corresponding form structures;

FIG. 2 is a perspective view of the tie rod bracket showing a modification of riser connecting members;

FIG. 3 is an illustrative arrangement of assembled brackets of this invention.

The bracket of this invention is adapted to be used in the construction of a solid concrete sloping slab-type structure having a stepped surface. In such a construction, a sloping soffit is provided, usually made from plywood and the like. A plurality of risers 11 are adapted to extend transversely of the soffit 10 in a raised relation with respect thereto, as shown in FIG. 1. As shown in FIG. 3, there is illustrated an inclined soffit 10 having mounted thereon a plurality of the bracket assemblies 12, all of which are freestanding and ready to receive their respective risers 11, such as in the manner shown in the lowermost row of bracket assemblies of FIG. 3.

The bracket assembly 12 comprises an elongated riser supporting rod 13. The lowermost end portion of the rod 13 is formed to provide a point 14 so as to resemble a naillike member. A restraining washer 15 is fixedly journaled on the rod 13 adjacent the point 14 thereof.

A first horizontal rod 16 extends perpendicularly to the riser supporting rod 13 and is welded thereto as at 17 inwardly of its one end 18. The opposite end of the rod 16 is bent as at 19 at a right angle to the longitudinal length thereof and has its extremity pointed as at 20 to resemble a naillike member.

A second horizontal rod 21 is adapted to extend perpendicularly to the longitudinal length of the riser supporting rod 13 and is welded thereto as at 22 inwardly of its exposed end 23. The opposite end of the rod 21 is bent as at 24 at right angles to its longitudinal length and has its extremity pointed as at 25 to resemble a naillike member.

The second horizontal rod 21 is of a length less than that of the first horizontal rod 16 and is connected to the riser sup-' porting rod 13 intennediate its ends and at such a distance from the connection of the first rod 16 thereto that its naillike end member will be projected into the sloping soffit 10 at a point equidistant to the insertion of the naillike end 14 of the riser supporting rod 13 and the naillike end member of the first horizontal rod 16, as shown in FIG. 1.

As shown in FIG. 3, the uppermost rows of bracket assemblies 12 have been mounted in horizontal alignment upon the soffit 10. In such a condition, these bracket assemblies 12 are ready to receive the riser 11. As shown in FIG. 1, the riser 11 is provided with suitable apertures which will receive the free ends 18 and 23 of the rods 16 and 21, respectively. These free ends 18 and 23 may be formed to receive a waler bracket 26, such as shown in association with the rod 21, or they may be provided with external threads to receive a restraining nut 27, such as shown in association with the rod 16. Both of the rods 16 and 21 adjacent their free exposed ends 18 and 23 are provided with stop washers 28 and 29, respectively.

As shown in FIG. 2, the rod 30 has welded to its free end 31 a preformed mounting pin 32 which includes an enlarged annular stop flange 33, an insert plug 34, which is adapted to be journaled into the aperture formed in the iser l1, and a headed stud 35 which is adapted to be pro ected into a bayonet slot formed in a flange member (not shown) of the waler bracket 26.

As further shown in F IG. 2, the second rod 36 has its free end 37 welded to an enlarged stop washer 38 which provides a laterally projecting internally threaded stud 39 which may receive a connecting bolt of any type of waler supporting bracket. When the complete bracket is assembled to the soffit 10 and riser 11, as shown in FIG. I, and the waler bracket 26 is connected thereto, a waler 40 is supported thereby and extends longitudinally of the riser 11. By this arrangement, the riser can be positioned on the rods 16 and 21 is a plumb and level condition.

After the form has been filled with concrete and the concrete has been cured, such that the soffit 10 can be removed, the pointed naillike end portions of the rods 16 and 21 can be readily removed by reason of the presence of a breakback 41 formed adjacent to such ends in the manner well known in the trade. The waler bracket 26 and waler 40 may be removed as well as the riser form 11 and other structural members can be readily mounted to the exposed ends of the rods as hereinbefore indicated.

While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation and modification without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what 1 claim as new and desire to protect by Letters Patent is:

1. A tie rod bracket for assembling sloping slab-type concrete forms wherein said bracket comprises:

a. an elongated rod, one end of which is pointed for forcible projection into the sloping soffit of the form so as to be vertically disposed with respect thereto,

b. a first rod extending perpendicularly to the longitudinal length of said vertical rod and welded thereto inwardly of its one end with its opposite end angularly bent so as to extend in a parallel relation to said one end of said vertical rod,

0. a second rod extending parallel to said first rod and perpendicularly to the longitudinal length of said vertical rod and welded thereto inwardly of its one end, with its opposite end angularly bent to extend in a parallel relation with respect to said vertical rod and said opposite end of said first rod,

d. said second rod being of a length less than that of the first rod and connected to said vertical rod at a point intermediate its ends and removed from said first rod so that said one end of said vertical rod and the said opposite ends of said first and second rods are projected into the sloping soffit of the form equidistant from each other.

2. A tie rod bracket as defined by claim 1 wherein said one end of said first and second rods are provided with means to which may be detachably connected a waler support and the riser portion of the concrete form.

3. A tie rod bracket as defined by claim 1 wherein said first and second rods are fixedly connected to said elongated rod by welding so as to constitute an integral bracket assembly.

4. A tie rod bracket as defined by claim 1 wherein said opposite ends of said first and second rods are formed into naillike members adapted to be forcibly inserted into the sloping soffit of the concrete form so that said bracket is freestanding with respect thereto.

5. A tie rod bracket as defined by claim 4 wherein one end of said first and second rods are provided with means to which may be detachably connected a waler support and the riser portion of the concrete fonn.

6. A tie rod bracket as defined by claim 5 wherein said first and second rods are fixedly connected to said elongated rod by welding so as to constitute an integral bracket assembly.
