CONCRETE WALL coNsTRUorIoNl applicationfued December 22,1325. y serial No. 77,044'. y

This invention relates to concrete wall construction, and particularly to movable forms as used for pouring such walls.

The principal objects of the present invention are to effectcertain improvements over the formsv shown in my Patent No. 1,550,051, issued August 18, 1925, Iwhereby the rising wall isvmore easily maintained perfectly vertical and the forms may be somewhat moreeasily assembled, together with improved mold and aligning connections making the use of my system of forms more practicable.

In the drawings hereto the improvements over'my earlier construction are shown, together with sufficient detaily of the earlier stgucture so as to make them understanda le.

' Figure 1 isa perspective view of a wall being erected with my improved forms showing'substantially all the features otl importance and with one of the hollow core molds raised vertically out of the wall forms.

Figure 2 is an enlarged vertical cross section of a portion of the wall to'better show the relation of the forms to the clamping and aligning devices.

Figure 6 is a fragmentary perspective view ofva concrete wallfbetween forms held together by my improvedcleats and tie wires.

Figure 7 is a longitudinal section of the wall forms showing my improved cleats and tie wiresfor holding the walls againsty outward pressure.

`Figure 8 is an elevational view of a cleat, to the upper end of which a 'similar' cleat is fitted, the upper cleat being shown as a fragment, and I y Figures 9 'and 10 are respectively sections taken on lines 9-9 and 10-10 of Figure 8.

Briefly explained lthe invention differs chiefly from my copending application showing a method of building concrete walls l1n which the wall forms were successively aligned upward against a. bar hanging from an elevated track, in providing a double track forv thebar, oney above the proposed walland the other at the base 'or ascending surface` with t-he vertical aligning barsheld vertically at all times on these two tracks in-` l dependent of the rising wall so as not tobe influenced by it and thus avoid an incrementalmisalignment of the wall toward one or. both sides, as possible with my"earlier system if the forms were not perfectly cleaned before clamping to the'a-scendingy wall, or not clamped tightly enoughthereagainst.

Other improvementsconsist in the details of the structure. 1" l In Figure 1a concrete wall in proce'ss of construction near the corner oft-he ,building is shown. `The finished portion ofthe wallr is designated 1, Vwhile arranged alongits upper edge are two rows of my wall forms 2,-

some with and some without coresv 7in position, and some being filled with vconcrete 4 from a. spout 5, others entirely filled. as at 6, and stillothers where the concrete'has set 'as at 7 and thecores have beenremoved showing the hollow wall spaces-8.

vAt each corner of the building are arranged'vertical forms comprising innerand outer right angle boards 9 and10 spaced by taper bolts 11, while the lmain wall forms compriseeach a pair of boards 2 also spaced y withtaper bolts 11 as similarly shown in my copending application referred to, and also by upper straps r12 though inthi's case unsecured to the upper edges of the formv boards. i f' Y Y The straps 12 as more clearlyfshown in Figure 5' are formed with several lugs or y ities? downward projecting pieces 12v adapted to simply'be positioned'over the form` sides as i indicated in Figures 1 and 2 so as to hold Contact with'the form sidesare for use with narrower wall construction-wherein the form sides are'to be held closer together, thus one set of straps is suitable for spacing the form sides for yseveral thicknesses of walls.y

Atthe outsides of the boards 2 are .ver-v 'tical` cleats 13 preferably out at an angle at the ends' so as toiproject from the vvupper form a few inches'over the side of the lower form.

In arranging arow. ofthese forms along lthe yform sides rigidly against inward or outH f -.ward deflection. The two inner .lugs notin each new row of forms is supported on the fr 'as more clearly shown in Figurev 3 andv` which bars are' adjustable along a pairv o t horizontal .i tracks .16 and 17T aligned; vert1- callyiover one another and to whichptracks the bars are supported by-hook `ghangiers 18 so.

39 and 50, While the tie wire 56 is looped around the reduced portion 47 or' the rib 40 just below the

flanges

43 and 44;. These tie Wires extend through the Wall forms 2 and around the ribs, and another pair of cleats identical with the pair of cleats 39 and `50. It will thus be readily seen that by tightening the Wires and 56. the vcleatsrmay be held to the Wall forms. L The tie vWires 55 and 56 are provided respectively with loops 58 and 59 by Winding` Wires (50 and 6l respectively around them. These loops are for the vpurposeof centering the core hereinbeiore described. lVhen it is desired to remove the lower Wall forms, the lower tievvire 56 is cut and the forms may then be removed, this removal being" facilitated by the arcuate edges or the rib of the cleat and the pro-v vision of the slot 48 in the rib.
