This invention relates to" devices used in the construction offormsinwhich concrete walls arepoured or cast,and has s'pe'cialreference to themeans of fastening the two separated wall-forms together across the space-for the concrete wall, whereby the said -;forms are rigidly held inspace-d relation to each other during'the' pouring and setting of the concrete wall, whereby-the wall-is formed of the required thickness.
i In the construction of'w'all-forms for concrete walls it is usual to tie the two forms together at suitable intervals=by"m eans of'a wire loop which extends around the studding of both forms and which has its ends twisted together to tighten it, and to insert wooden spacers between the said forms to hold them apart against the tension of said loops. This form of construction is very" slow and is consequently expensive in labor and necessitates the removalof the wooden spacers before the pouring of'the concrete, and-also leaves the ends of the wires formingthe loops protrud" ing from the surface of the-concrete after theforms have'b'een removed.- I l v' I haveinvented the following'described devices whereby the speed of erection of'the forms. is greatly increased; the labor required is decreased; thetie' and spacer a'rem one unit; the said units being set up with the first wall-form and hung thereto without being in the way of the workmen on the inside of the wall-space, and may be later linked into the complementary wall-form, as it is erected, to hold it in proper spaced relation to the first said wall-form; which is stiff, strong and substantial; which can be manufactured in wholesale lots for walls of various thicknesses, at a low cost; to which all the reenforcing bars of the concrete wall may be suitably attached; which automatically forms the space of the required thickness for the concrete; in which the central tie part may be made of standard lengths for use in walls of standard thicknesses; in which the same central tie part may be used in walls of three thicknesses; in which the loop parts may be formed of standard dimensions for 'use with studding of standard sizes; in which the loops are weakened at points adjacent to but within the surface of the concrete being formed and may be broken off thereat after the molding form has been removed, thereby leaving the wall without any projecting wires; in which the loops are nailed to the studding while in use and may be easily disengaged therefrom by removing a single nail at each end; in which the loops are formed of thin flat metal strips and lie flat between the form sheeting planks, thereby avoiding the'necessity of cutting or boring holes iii-said sheeting to permit said loops to pass therethrough to the'studding, and in which the loops are twisted to form said flat portions and in all other parts lie with their wider dimensions vertical; and
which are cheap to make and, more particularly, save considerablc'labor costs in erecting and removing the concrete forms.
I attain these'and other objectsby the devices and arrangements illustrated in the ing drawing, in which- Fig. lis across-section of a pair of wall-forms showing, at the top, the tie secured to the finished f orrn and hanging freely therefrom; at the center,
the tie completed across the two forms and ready for the next tier'of sheeting on the second form;
and at the lowerend, a tie asset in the concrete;
Fig. 2 is a horizontal section of the wall-form showing my improved tie being applied to the second frame and in position'similar-to that shown at the center of Fig. 1; Fig.3 is an elevaton of 'that porti on of one end of the tie and loop, showing particularly the portion passing between the sheeting planks; Fig; 4 is an elevation of the end of one of the legsthereof; and-Fig.6 is'a section of a piece of the concrete wall after theforms have been removed and the tie loop ends broken therefrom.
Similar numerals of reference refer to similar parts throughout the several views.
Referring to the drawing, it will be seen that my apparatus, at each tie point in the wall, comprises two similar loops attached to their respective wall-forms, and a single tie and. spacer connecting the two said loops.
The wall-forms are of the usual construction, namely the studding 1 and sheeting planks 2 of the first constructed side, and the studding 3 and the sheeting planks 4 of the second constructed side.
It will be seen that the tie or tension piece 5 comprises a straight metal strip of substantial -accompanydimensions, having a series of holes 6 punched,
. or otherwise formed, near each end, each of said holes 6 being of general triangular shape having i a straight vertical side adjacent to the end of the tie 5 and two curvilinear sides, and adapted. to receive the hereinafter described loop, and to permit it to be slid or threaded through said hole, and yet not permitting any substantial slack or looseness therein.
Each loop is comprised of a flat metal strip bent substantially as shown in the drawing, namelyz-beginning at one end '7 having .a hole 8 therein (said hole 8 being adapted to cooperate with a complementary hole in the other end of the metal strip to receive the attaching nail 9) said end or foot 7 lies with its fiat side on the outer narrow side of the studding 1, or 3; then there is a right-angle bend to form the leg 10, adapted to lie against the wide side of the said studding; followed by a bend at about thirty degrees and a one-quarter twist at 11 to turn the flat side of thestrip into horizontal position to form the leg 12 which is adapted to lie between the edges of two of the sheeting planks 2, or 4; followed by a second one-quarter twist at 13 to bring the flat side vertical again and to form the strap 14 which extends to the tie piece 5, passing through the hole 6 therein and bending at its center, and then bent back and twisted in inverse order from the above and in complementary manner thereto, to complete the loop, the last part or foot 15 thereof lying on the first foot 7 and having its hole 16 concentric with the hole 8,
the attaching nail 9 passing by both holes through the feet 7 and 15 and firmly attaching the loop to the studding 1 or 3. Two weakening holes 1'7 are made in the second twists 13 at the strap 14.
My invention is set up and used in the following manner:The studding 1 being in place, the sheeting 2 is nailed thereto in the usual manner; then one of the loops, having a tie .5 threaded thereon and hanging freely therefrom (Fig. 1)
isopened sufficiently (Fig. 2) to pass around the studding 1 to which it is secured by a nail 9 (which need not befully driven home), the flat legs '12 thereof lying on the top edge of the sheeting 2 (Fig. 1), then the next tier of sheeting 2 is placed on top of said flat legs 12 andis forced down thereon and nailed to the studding 1, until the first form is finished, then the second wall studding3 is erected and the second loops are successively passed through the holes 6 in the free ends of the hanging ties 5 :(Fig. 1) and are bent open (Fig. 2) to permit them to be passed around the studding 3 and the legs 12 thereof lie on top of the sheeting 4 and then the nails 9 areinserted through the holes 8 and 16 thereof and are partially driven into the studding 3, thus securely tying the two wall forms together. Then the next tier of sheeting 4 is placed on the top edge of the lower tier and on top of the said legs 12, and is in turn nailed to the studding 3.
When the second wall-form is completed the concrete is poured and when it is sufficiently set the forms are removed. This is accomplished by drawing all the nails 9 and opening the loops, removing the studding and the sheeting and bending the metal of the loops, extending from the wall, at the twists 13 in such manner as to break the said parts at the weakening holes 17, thus breaking them off at points back of the face of the concrete wall.
- It will be observed, therefore, that the complementary wall-forms are tied together by the tension of the tie 5 pulling on the loops, and that these loops are securely held in closed position around the studding by means of the nails 9 driven in the outer side of both the wall-form studdings and that substantially no backlash is permitted by the shape of the holes 6 which keep the straps 14 from having any excessive play therein. It is also evident that with two sets of holes 6 in the said ties 5 that three sizes of walls may be formed with ties of the same size, thus economizing on the cost of manufacture.
Having thus described myinvention, what I claim and desire to secure by Letters Patent, isz- 1. A wall-form tie comprising a pair of loops, each formed of aflat metal strip bent around the studding of the respective wall-form and projecting into the-wall space at its center together with a tie piece having substantially triangular holesnear its ends through which said loops are threaded whereby the loops arepermitted to hang freely therefrom when not in use and are prevented from excessive slack when in use, said tie piece being adapted to hold the wall-form studding against outward pressure of the concrete poured therebetween. Y
2. A wall-form tie as set forth in claim 1, wherein the flat metal of said loops have their wide dimensions vertical both in contact with said studding and within the wall space, but have double reverse quarter twists to bring their wide dimensions horizontal as they pass through the wall forms.
