srannmm'rrn FOR CONCRETE-WALL roams.
Application filed February 19,1927. Serial No. 169,576.
This invention relates to improvements in spreaderties for concrete wall forms The primary object of the invention resides in "a concrete form spreader tie for 6 holding the form sections in rigid spaced relation and which facilitates the quick setting up and taking down of said sections.
Another object of the invention resides in a spreader tie in which certain elements of the same are left in the concrete wall structure, after the wall has been formed and the form sections removed therefrom to serve as a reinforcement for the wall.
A further object of the invention is to provide a spreader tie which is simple 1n construction, inexpensive of manufacture and highly eflicient for the purpose intended.
With these and other ob ects in view, the
invention resides in certain novel construc-' tion and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated inthe accompanying drawing, in which Figure 1 I is a throu h a wall. form with my improved sprea er tie in position thereon.
Figure 2 is a vertical transverse sectional view on the line 22 of Figure 1.
Figure 3 is a perspective view of the.
spreader tie per se.
Figure 4 is a verticalv sectional view through a portion of a concrete wall structure with the form removed.
Referring more particularly to the drawing, the reference numeral 10 designates a concrete wall form which includes wall sections 11 and 12, each of which comprises vertical beams 1 3to which horizontal boards 7 14 are fastened.- a
Our improved spreader he is des1gnated in its entirety as at 15 and comprlses a brace member 16 constructed of ,flat metal twisted betweenitsfends' as at 17., The ends of the member are bent at right angle to the longitudinal axis. of the body of the. same to provide ears 18 through which the inner ends of a pair of rods 19edztend. The rods 19 extend through the vertical beams 13,
, boards 14, ears 18 and through" horizontal cross beams 20, which cross beams are supported by said rods. The ends of'the rods are screw vertical sectional view and to provide an irregular contour tothe threaded as at 21 and 22 respec-- tively and co-acting with. the screw threads 21 are-corrugated cone members 23, which.
abut the inner faces of the form sections and the ears 18. Square nuts 24 also co-act with the screw threads 21 and are prevented from rctat'ion by the flat face of the brace member For clamping the parts in position, we apply wing nuts 25 tothe outer threaded ends 22 of the rods and which nuts arescrewed home against the horizontal beams 20.
After the concrete has been poured into the concavity formed by the form sections and set, the said sections are removed by unscrewing the outer wing nuts 25 and turning the rods 19 to unthread the nuts24 and corrugated cone members 23. The nods are then withdrawn and the form sections removedfrom against the wall. The brace member 16 and nuts 24 remain embedded in the wall structure as shown in Figure 4 of the drawing and act to reinforce the wall. The corrugated cone members 23 will also remain-in the wall as the form sections are removed but the same are pried loose from the cement wall and the coneshaped recesses formed thereby, are filled with cement so as to conceal the brace member and to .im-
part a flat finished appearance-to the wall structure. By making the member corrugated,'- the walls of the recesses formed thereby are correspondingly corrugated to more readily anchor the cement filler in place. It might be mentioned that the brace member 16 is twisted to strengthen the same.
same so that waterwill not easily seep through from one side of the wall to the other. 4 I v What is claimed as-new is 1. A concrete form spreader tie compris ing a fiat twisted brace member, removable rodsextending from opposite ends of said brace member, corrugated cone members mounted on said rods and abutting the ends of said brace member, andclampmg means.
on said rods substantially as and for the purpose specified. f t
2. In combination with a pair of concrete form sections, a bracebar interposed between said sections, angularly dis osedears on the ends of said brace bars, ro s remova bly connected to said ears, said rods extending through the respective form sections,
cone shaped members on-said rods ml interposed between sa d ears and sa1 form.
sections, and clampinlg elements carried by from rotation by brace bar, cone shaped 10 the outer ends of sai rods substantially as members mounted on said rods, and clampand for the purpose specified. ing nuts co-acting with the outer threaded 3. A concrete form spreader tie comends of said rods substantially as and for the I prising a. twisted brace her having ears on purpose specified.
the ends thereof, a pair of rods having In testimony whereof we hereby aiiix our '15- threaded ends, the inner ends of the rods exsignatures.
tending through said ears, nuts threaded on CHARLES T. wniTEs'cARvER. the inner ends of said rods and prevented GEORGE BENDIXEN. v
