Abstract: A retainer clip for use with concrete form tie for retention of reinforcing rods has a one-piece body which includes a header, and first and second clips extending angularly therefrom, spaced apart in a first direction, and defining therebetween a generally u-shaped opening sized to slidably receive a reinforcing rod of generally circular cross section. Each of the clips include first and second prongs spaced apart in directions lateral to the first direction, and at least two prongs of the clips further define therebetween a narrow generally rectangular passage which intersects at least a portion of the u-shaped opening, and is sized to receive at least a notched form tie of generally narrow rectangular cross section. The retainer clip secures the reinforcing rod in position substantially against the form tie in a notch to inhibit both relative motion in the first direction and substantial separation therebetween.

Abstract: A spacer is provided for locating a reinforcing cage or fabric, with respect to a form, when manufacturing reinforced concrete articles such as piping, manhole sections, walls and the like. The spacer is formed from a single length of heavy gauge steel wire, and includes a mounting section which wraps around a longitudinal rod of the reinforcing framework and abuts a transverse rod at its junction with the longitudinal rod. An intermediate section of the spacer extends transversely from the mounting section and is approximately parallel to the transverse rod. A hook at the end of the intermediate section remote from the mounting section is positioned to latchingly engage the transverse rod responsive to elastic deformation of the spacer, thereby to securely maintain the spacer on the reinforcement framework. A spacing loop of a predetermined dimension is provided along the intermediate section.

Abstract: A support chair for supporting reinforcement for foundations in which there is a turret shape and a lower base, the turret shape having a plurality of upwardly open slots into which the reinforced rods may be located the shape of each of the slots being such as to provide for interlocking of each rod particularly by providing a narrower part of the slot through which the rod must squeeze to a lower wider part.

Abstract: According to the invention, reinforcement bars (1; 11; 21; 22) which are usually welded, are assembled by means of clips (30) which are elastically clipped in position at the nodes formed by the bars (2, 12, 21).These clips also perform a spacing function when the reinforcements are placed in position in the moulds employed for manufacturing reinforced concrete products.Application in particular in the manufacture of reinforced concrete ties.

Abstract: A spacer assembly including a spacer with a body having a base portion with a generally centrally disposed support post portion, one end which is formed as a planar surface with a centrally located generally concave saddle portion configured for receiving a reinforcing bar, the planar surface being provided with apertures therethrough on both sides of the saddle. A clamp member is provided for simultaneously securing mutually perpendicular rebars to the chair, the clamp member including a generally U-shaped lower portion, with the depending arms thereof in spaced generally parallel relation for engaging a first bar within the saddle. A pair of generally identical hook arms extending upwardly from the bight portion, the hook arms being oriented for engaging a second rebar in an orientation perpendicular to a first rebar engaged within the saddle portion.

Abstract: A spacer device for use in supporting bar-like members in construction applications, the device including a body having a plate portion with a support post portion having a saddle configured on the upper edge thereof, with a plurality of legs affixed to the plate member and extending generally perpendicular thereto. The support post is provided with either an aperture for passing fastening wire therethrough for securing the bar or a pair of aligned openings for receiving a U-shaped clamp member. The plate portion is provided with recesses in alignment with the legs to permit stacking of one spacer atop the other for building layers of rebar framework. The legs may be removable for reverse connection, thus permitting the plate portion to be used as a "sand plate" support for reinforced concrete construction, or alternatively a separate "sand plate" may be used.

Abstract: A reinforcement support spacer for spacedly positioning one or more concrete reinforcement members from a surface on which concrete is poured. The spacer comprises a support which has at least one recess therein for receiving a reinforcement member. Barbs or tines formed integrally with the support project into the recesses. The barbs or tines on each recess are oriented so as to permit a reinforcement member to be forced past the barbs or tines into the recess but substantially to prevent a reinforcement member from being forced past the barbs or tines out of the recess once a reinforcement member has been inserted into the recess. The support spacers of the present invention permit reinforcement members to be preassembled in spaced relationship to each other and installed as an assembly. The preassembled reinforcement assembly can be lifted onto the surface on which concrete is to be poured, saving on-site labor costs involved in assembling at the point of use.

Abstract: A spacer for reinforcement mats in a framework has a spacer bar to which there is fastened at least one double-leg clamp the legs of which define an edge-open opening of substantially U shape which is adapted to the cross-sectional dimensions of a bar of a reinforcement mat, the opening having associated with it a spring barrier which closes the opening and holds the clamp in non-detachable manner on the bar of the reinforcement mat.In order to design the spacer for larger stresses while still assuring simple possibilities of manufacture the clamp (3) is developed in the form of a flat plate (5) which is fastened in the region of the bottom of the U-shaped opening (6) to the spacer bar (1) and the barrier is formed by a spring element (11, 11a, 11b, 11c) which is anchored to one leg (7, 8), extends into the opening (6) and can elastically be moved away laterally towards the leg.

Abstract: A support is provided for reinforcing rods or mesh. The support includes a plate of substantially planar construction. A cruciform structure is provided beneath and supporting the plate. The cruciform structure includes a plurality of legs and tips depending from the legs. The tips are adapted to expose a relatively minimal part of the support with the support being embedded in a substance such as concrete. On top of the plate is provided a structure to limit movement of the rod or mesh transversely of the plate. Specifically pairs of pins toed in towards one another are employed or fins are employed with ramps thereon to restrain the movement of rods or mesh which are supported on the plate.

Abstract: A bar support for supporting a plurality of longitudinally extending reinforcing bars and a transversely extending reinforcing bar includes a cross rod which is positioned beneath the transversely extending reinforcing bar and extends along the bar in parallel relationship, and a plurality of bar support chair means which are laterally spaced along the cross rod. Each of the bar support chair means includes a first member having a first vertical leg portion extending above and displaced from the cross rod and a second member having a second vertical leg portion extending above and laterally displaced from the cross rod on the opposite side of the cross rod from the first leg portion. Longitudinally extending reinforcing bars are held between the leg portions transversely to the cross rod, and the transversely extending reinforcing bar is held between the leg portions parallel to the cross rod.
