Abstract

Concrete casting elements for forming an expansion joint in concrete including: a pair of expansion joint members each having a gasket mounting formation to which a gasket may be mounted in operative interposition between the expansion joint members for sealing the joint; a flange extending from a remaining portion along one side of the expansion joint member and retainer mounting means formed onto or into said remaining portion for mounting one or more retainer elements to protrude from the opposite side of the expansion joint member from the flange; the flanges of each one of the expansion joint members being formed to engage one with the other; the flange of one joint member at least partly overlying the flange of the other to provide an expansion joint upper face and such that the remaining portions may be spaced from one another when the flanges are so engaged; the flange of the other expansion joint including a lip formed to be substantially coplanar with the expansion joint upper face; and the flanges also being formed and positioned for protection of the gasket against damage.

Goods & Services

Building materials (non-metallic) in this class; building products (non-metallic) in this class; non-metallic forming aids and forms, including non-metallic forms for use in casting concrete; non-metallic expansion joints, including non-metallic expansion joints for placement between concrete slabs; bar chairs, profiles and other devices, all being made primarily of non-metallic materials, and all being primarily for the purpose of providing support for reinforcing materials to be retained within cast concrete.

Abstract

Crack inducer apparatus including: a support body and a cracking strip fixable to the support body, the support body having: two or more mounting formations formed for mounting to separate reinforcing bar, each mounting formation being spaced from another or the other mounting formation by a predetermined spacing and being formed to prevent rotation about an axis orthogonal to the separate reinforcing bar when mounted thereto; and one or more strip fixing formations formed to accommodate fixing of the cracking strip to the support body; a trunk assembly from which the mounting formations and the or each strip fixing formations extend, each formation having a spatial disposition with respect to the other formations; the cracking strip having two opposed faces substantially parallel to one another, a straight edge along an edge of each face and one or more complementary fixing formations formed for fixing to the or each fixing formation of one or more of the support bodies, and wherein: the spatial disposition of the formations being such that the straight edge of the cracking strip is arranged substantially parallel to the separate reinforcing bars to which the mounting formations may be mounted when the cracking strip is fixed to one or more of the support bodies.
