Abstract
Abstract At the mounting of joint sealing strips in moulds for concrete casting use is at present made of iron wires or like means which from the joint sealing strip are drawn forth to suitable fastening points at the mould or at the reinforcement placed in the mould. Such a mounting procedure results in an insufficient bracing of the strip and it often happens that the strip collapses under the weight of the concrete masses poured into the mould for the casting operation. The invention has for its object to provide a device which ensures a reliable fixation of joint sealing strips. This device comprises members formed as brackets which are fastened in positions extending transversely across the joint sealing strip so as to keep the strip stretched in the transverse direction. Iron wires or like means serving to localize the strip may be fastened to the brackets in question.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
295 words
A sealing strip assembly for molding into reinforced concrete to act as a waterstop at the joint of two adjacent concrete elements comprising an elongated relatively wide and substantially flat strip of resilient waterproof material having a central portion adapted to be positioned at the joint between the two concrete elements and a pair of oppositely directed side flanges adapted to be molded one in each of the concrete elements at the time of casting these elements, and a plurality of pairs of holes formed in the strip at spaced intervals along the length thereof with one hole of each pair being located adjacent the outer edge of each of the flange, an elongated bracket formed from a rigid resilient material and including a body portion extending transversely across said strip adjacent a pair of said holes and having a length greater than the width of said strip, a reversely bent arm portion integrally formed on said body portion at each end thereof and projecting inwardly and laterally therefrom in position to project one through each hole of one pair of the holes in the strip, said arms and body portion cooperating to define an inwardly open generally U-shaped portion positioned outwardly from the holes and spaced from said strip and a hook portion on the end of each said arm in position to releasably retain the strip on the bracket when said arms are positioned in the holes, said hooks being spaced apart a distance at least as great as the holes of the pairs of holes whereby the bracket is adapted to retain the strip in a substantially flat outstretched condition, said U-shaped portion being adapted to embrace a concrete reinforcing element to support the assembly in position during casting of the concrete.

Claim 3
Dependent Claim
28 words
The assembly as defined in claim 1 wherein said body portion, said arms and said hook portions are formed from a single piece of resilient spring steel wire.
