June 28, 1938. G. I. RERlcK I SYSTEM FOR CONCRETE CONSTRUCTIONS Filed Feb. 24, 1936 l @zaag: JwBP/CA BY I ATTORNEY UNITE Patented June 28, 1938 STATES PATE.

This invention relates to mold or form ties for the construction of Walls of concrete and similar materials and has for the primary object the provision of efiicient and durable ties which may be readily adapted to and removed from forms and which will form in the faces of the molded material grooves which when filled or pointed up provide to the wall the appearance of being constructed from bricks, blocks or similar devices.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary front elevation showing a partially constructed wall with the form applied thereto and equipped with my invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1 showing a tie and shield therefor and groove-forming element.

Figure 3 is a perspective View showing one of the groove-forming elements.

Figure 4 is a perspective view showing another groove-forming element.

Figure 5 is a perspective view illustrating a supporting block.

Figure 6 is a fragmentary sectional view showing a modified form of tie.

Figure 7 is a fragmentary sectional view showing the modified form of tie connected to one of the groove-forming elements.

Referring in detail to the drawing, the numeral. l indicates a sectional mold or form designed for molding concrete or similar material into wall formation. The inner and outer walls of the form are held assembled by removable ties 3. Each tie includes a stem 4 with a head 5 at one end and a slot 6 adjacent the opposite end. A removable head I is applied to the last-named end of the stem and retained thereon by a wedge 8 extending through the slot. A tie of the character described is readily adaptable to the form.

A sleeve 9 is placed about the stem 4 and has cup-shaped ends in. Also mounted on the stem 4 are groove-forming elements H each of substantially U-shape in end view and provided with angularly disposed flanges H2. The groove-forming elements I I are apertured to receive the stems 4 and seat in the cup-shaped ends ll] of the sleeve and lie between the sections of the form and horizontally with respect to the form. Arranged between the groove-forming elements it and at spaced intervals are groove-forming elements it each of substantially U-shape in end view and equipped with angularly disposed flanges M. After the assembling of the form with my invention adapted thereto concrete or similar material is poured into the form and to prevent any danger of the groove-forming elements collapsing under the weight of the sections of the form a. series of blocks or wedges l5 are provided. These blocks at spaced intervals are positioned within the groove-forming elements, as shown in Figure 1. After the setting of the concrete or similar material, the groove-forming elements are removed along with the ties 3, leaving the sleeves 9 and their cup ends l0 embedded in the concrete. The sections of the mold are then removed leaving the molded material in opposite faces thereof with a series of grooves. These grooves are pointed up or filled with mortar giving the faces of the wall the appearance of blocks, bricks or like devices.

Referring to my modified form of invention, the body portion I6 of the tie may be constructed of a composition of material such as concrete and has its ends cupped and also embedded therein anchoring or tying elements H. The tie elements ll may be passed through openings in the groove-forming elements H, as shown in Figures 6 and 7. Thus it will be seen that in this form of the invention the groove-forming elements act as anchoring ends for the ties.

Having described the invention, I claim:

1. A combined tie and grooving means for concrete structures comprising a plurality of tubular members having flared opposite ends, an elongated groove forming member U-shaped in cross section disposed at each end of said tubular member, laterally projecting flanges carried by the opposite legs of said groove forming members and engageable against the outer surface of opposed form members, the legs of said groove forming members having a length sufficient to dispose the bights thereof inwardly of the inner faces of said form members, the bights of said groove forming members seating in said flared ends of said tubular members, and tie members extending through said tubular members and said groove forming members and engaging against the outer sides of said flanges.

2. A combined tie and grooving means for concrete structures, comprising a plurality of tubular members having flared opposite ends, an elongated groove forming member U-shaped in crosssection disposed at each end of said tubular member, laterally projecting flanges carried by the opposite legs of said groove forming members and engageable against the outer surface of opposed form members, the legs of said groove forming members having a length sufiicient to dispose the bights thereof inwardly of the inner faces of said form members, the bights of said groove forming members seating in said flared ends of said tubular members, spaced apart tie members extending through said tubular members and said groove forming members and engaging against the outer sides of said flanges, and a plurality of blocks engaging between the legs of said groove forming member between pairs of said tie members to hold said groove forming member against collapsing.
