In Patent No. 1,794,684, issued. to, me on- March 3, 19.31,. for an: Anchor for; veneered concrete structures I disclosed an: anchor device; for the same purpose as my present invention.
One of the objects of my present.- inyention is to: provide an anchor device'of. this classcontaining less material and, hence, of cheapened construction.
A further object is to provide any anchor'device containing a, wooden. removable: form. member in which the wooden form membermay be readily, quickly and easily removed, resulting in a saving of workmens time.
A further object is to provide an anchor device of this class in which all of: the surfaces of the anchor member, which after installation are projected beyond the concrete wall", are, during: the pouring of the concrete wall, thoroughly sealed from contact with the plastic concrete, and whereby no concrete canadhere to any part thereof, hence, there is no necessity for removing concrete from such exposed portions of the anchor member, and further in this connection toso construct the wooden anchor formmember that after the concrete has set and the concrete mould forms have been. removed, there will be no concrete Within the wooden anchor form member which might interfere with its ready and easy removal from the anchor member.
In the accompanying drawing- Figure 1 shows a perspective view of a sheet metal anchor member;
Figure 2 shows a transverse sectional view through the sheet metal anchor member, the anchor mould form imbedded in a concrete wall, and a concrete wall form having the anchor mould form detachably connected therewith;
Figure 3 shows a similar sectional view with the anchor mould form and the concrete wall form removed, and a tie hook placed in position in engagement with the anchor mould form;
Figure 4 shows a perspective view of the completed concrete wall having my improved anchor I I2 atthe; outeredge of the; doubled side members. Formed. in the side members II at points sub stantially' spaced from the doubled edge Ill is a series of slots I3 arranged parallel with the doubled edge I0, and spaced; apart from each other to thereby form between the slots at, Iz4- a con:- tinuous transverse solid metal portion extending throughout the doublededge II) and the sides I I and the flanges: L2,. to; thereby thoroughly brace and reinforce the doublededge portion III against outward movement away from the flanges I2.
The anchor mould form, which is preferably formed of a wooden strip, comprises a body p rtion l-5 having one edgeat I6 fiat and the; op,- pcsite edge atv II rounded. Formed in the longitudinal portion of this, strip extended from the center of the rounded edge toward the flatedge is a longitudinal groove, the depth of which is nearly as, great as the. thickness of the strip so that the amount of material between the groove and the flat side of the. strip is quite thin.
The tie hooks illustrated in Figs. 3 and 4 comprise a body portion I8,,having a hook I9. at one end shaped to conveniently and easily enter one of the slots I3 and. to. be extended outwardly therefrom, and having. a. hook-shaped portion 20 at its other end, all being substantially in the same horizontal plane so that when hooked to the anchor member, as shown in Fig. 4, the body portion of the tie hook may rest flat against the top of one of the bricks of a brick veneer wall, to be permanently held in this position by the mortar between the bricks.
In the modified form shown in Figure 5 I have formed the anchor member of a strip of sheet metal comprising a body portion 2| having at its edge that is to be imbedded in the concrete wall, a series of alternately arranged, laterally extended flanges 22, and also having slots 23 similar to the slots I3. An advantage of this construction is that it effects an economy in the material necessary for making the anchor memher.
In practical use a wooden strip I5 is applied to the anchor member, as shown in Figure 2, with the sides of the groove in the wooden strip, tightly fitting against the sides of the anchor member and extending to points beyond the slots I3 in the direction toward the flanges I2. These wooden strips are then applied to the inner face of the concrete wall form, preferably by staples over metal and wood strips, as shown in Fig. 2, which are easily removable with the wooden strips from the concrete wall form. When thus placed in position, the concrete wall 25 is poured and permitted to set and harden, then the concrete wall form is removed, and thereafter the operator removes the wooden anchor mould form from the bottom of the slot to the adjacent flat surface thereof, which may be readily and quickly done. When this has been don there is presented on the outer face of the concrete wall a shallow longitudinal groove, the inner surface thereof being rounded, with the doubled central portion of the anchor member projected outwardly through the center of this groove to a point close to a line parallel with the surface of the concrete wall. This groove and the exposed portions of the anchor member are absolutely free from any cement going through the concrete wall when it is poured, so that there is nothing to interfere either with the ready and easy removal of the wooden mould form or with the ready and easy placing of the tie hooks in the slots.
In the form of my invention shown in my said issued patent, the anchor member consisted of a wire with looped portions entering the concrete wall and the straight portions in slots in the surface of the concrete wall, and I have found that portions of concrete within the groove to permit the insertion of tie hooks.
With my improved construction all these disadvantages are overcome and the wooden strips may be readily and easily removed and the tie hooks applied without the necessity of breaking away or removing any portions of concrete within the grooves.
I claim as my invention:
1. A mould and anchor holding member for use with a mould form for pourable material and adapted to support an anchor having an elongated perforated flat portion, said mould member comprising an elongated strip having a flat side for engaging said mould form, and an opposite side of arcuate contour terminating at said flat side, said member having a longitudinally extending groove substantially centrally of said opposite side, with said groove having a depth for receiving the perforated part of said flat portion of the anchor therein and a width to tightly engage the sides of said fiat portion so that the pourable material is maintained outside the confines of said member and away from said perforated part, and means for attaching said member on the mould form.
2. An anchor holding mould member for an anchor member having a flat portion provided with perforations and adapted to be used with a mould form for pourable material said mould member having one side engageable with said mould form, and an opposite side with an anchorreceiving roove therein extended longitudinally of said mould member and coextensive in length with said mould member, with said groove being of a size to tightly receive the perforated portion of said fiat portion therein to prevent said pourable material from entering said groove and the perforations of the fiat portion within said groove.
3. The method of affixing in a concrete wall elongated veneer anchors having a flat portion with perforations spaced longitudinally thereof such that the perforated part of the flat portion is disposed in an elongated recess in the concrete wall with the perforation entirely open and free of concrete, which consists in providing an elongated mould member having a flat side and an opposite side of tapered contour, and a longitudinally extended groove substantially centrally of said opposite side, securing said mould member to the inside of a mould form with said flat side against the mould form, tightly fitting the perforated part of said fiat portion of the anchor veneer within said groove and completely filling the groove with said perforated part, and then filling the mould form with concrete and rea moving the mould form and mould member.
