CONCRETE CONSTRUGTIONS George I. Rerick, St. Petersburg, Fla. Application February 24, 1936, Serial No. 65,475 2 Claims. (01. 25-431) horizontally with respect to the form. Arranged 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 e?icient and durable ties which may 5 be readily adapted to and removed from forms and which will form in the faces of the molded material grooves which when ?lled or pointed up provide to the wall the appearance of being constructed from bricks, blocks or similar de 10 vices. With these and other objects in view, this in vention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and 15 claimed. For a complete understanding of my inven tion, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary front elevation 20 showing a partially constructed wall with the form applied thereto and equipped with my in vention. Figure 2 is a sectional view taken on the line 2-—2 of Figure 1 showing a tie and shield therefor 25 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. 30 Figure 5 is a perspective view illustrating a supporting block. Figure 6 is a fragmentary sectional view show ing a modi?ed form of tie. Figure 7 is a fragmentary sectional view show 35 ing the modi?ed 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 40 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 45 end of the stem and retained thereon by a wedge 8 extending through the slot. A tie of the char acter 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 50 4 are groove-forming elements H each of sub stantially U-shape in end view and provided with angularly disposed flanges H2. The groove-form ing elements I I are apertured to receive the stems 4 and seat in the cup-shaped ends ll] of the sleeve 55 and lie between the sections of the form and 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 ?anges M. 5 After the assembling of the form with my in vention adapted thereto concrete or similar mate rial 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 re 15 moved 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 leav ing the molded material in opposite faces thereof with a series of grooves. These grooves are 20 pointed up or ?lled with mortar giving the faces of the wall the appearance of blocks, bricks or ' like devices. Referring to my modi?ed 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 there in anchoring or tying elements H. The tie ele ments ll may be passed through openings in the groove-forming elements H, as shown in Figures 30 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 con crete structures comprising a plurality of tubular members having flared opposite ends, an elon gated groove forming member U-shaped in cross section disposed at each end of said tubular mem ber, 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 ?ared ends of said tubular members, and tie members extend ing through said tubular members and said groove forming members and engaging against the outer sides of said ?anges. 2. A combined tie and grooving means for con crete structures, comprising a plurality of tubular members having ?ared opposite ends, an elon gated groove forming member U-shaped in cross 35 2 2,122,181 section disposed at each end of said tubular mem ber, laterally projecting ?anges 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 su?icient to dispose the bights thereof inwardly of the inner faces of said form members, the bights of said groove forming members seating in said ?ared ends of said tubu lar members, spaced apart tie members extend ing through said tubular members and said groove forming members and engaging against the outer sides of said ?anges, and a plurality of blocks engaging between the legs of said groove forming member between pairs of said tie mem bers to hold said groove forming member against collapsing.
