A rubber water stop

Abstract

The invention relates to a rubber waterstop, which comprises a rubber belt, a steel plate and a fixing structure. Steel plates are installed symmetrically on the front and rear sides of the rubber belt through bonding, and fixed structures are symmetrically arranged on the outer wall of the rubber belt. The rubber belt includes a belt Body, extended end, clamping end and convex tube, the fixed structure includes sliding frame, base plate, support plate and positioning bolts, the steel plate includes plate body, first connecting plate and second connecting plate, and the extending end includes extending block , a shrinkage hole, a clamping strip and a clamping block, and the clamping end includes a clamping block, a clamping groove and a clamping groove. The two ends of the rubber belt of the present invention adopt concavo-convex complementary structures to facilitate the docking of the two rubber belts. After the docking, the adjacent steel plates are connected to the fixed structure through bolts to strengthen and fix the joint. The rubber belt plays the role of support and positioning during the placement process to ensure the accuracy of the placement position.

Description

technical field [0001] The invention relates to the field of building construction materials, in particular to a rubber waterstop. Background technique [0002] The rubber waterstop is made of natural rubber and various synthetic rubber as the main raw materials, mixed with various additives and fillers, after mastication, mixing, and pressing, it has many varieties and specifications, has good elasticity, and is wear-resistant. Durability, aging resistance and tear resistance, strong adaptability to deformation, good waterproof performance. [0003] Rubber waterstops are divided into back-mounted waterstops and mid-buried waterstops according to their installation positions. The mid-buried waterstops are mainly fixed inside concrete such as concrete deformation joints and expansion joints. There are the following during installation question: [0004] (1) When the length of the part to be water-stopped is long, multiple water-stops need to be installed, and the butt joint...

AI Technical Summary

Problems solved by technology

[0004] (1) When the length of the part to be water-stopped is long, multiple water-stops need to be installed, and the butt joints of adjacent water-stops must be cold-joined or hot-joined. After that, the surface of the waterstop cannot be kept flat;

[0005] (2) During installation, in order to prevent the waterstop from turning over and kinking, it is necessary to use special clamps, additional steel bars, lead wires or templates to fix it. When the above fixing methods are used, it is unavoidable to make holes on the waterstop. Holes, the strength of the waterstop is reduced at the perforation, and cracks are prone to occur, which will affect the waterstop effect
