Abstract

The invention discloses a replaceable surface-layer combined water-stop structure for concrete structural joints. Grooves or reserved grooves are made on both sides of the structural joints on the concrete surface to form water-stop grooves. U-shaped rubber water-stop belts are glued The adhesive is glued to the bottom of the water stop, and two sets of stainless steel bolts are used to fix the two water stop pressure plates on both sides of the structural joint parallel to the structural joint, and the U-shaped rubber water stop is pressed tightly on the bottom surface of the water stop On the top, the raised U-shaped part of the U-shaped rubber waterstop is inserted into the structural split, and the sealant is injected between the gap material in the structural split and the raised U-shaped part, and the upper part of the U-shaped rubber waterstop Fill the elastic material, fill up the water stop groove, and paint the elastic waterproof coating on the surface of the water stop groove after filling, and the elastic waterproof coating will span the entire water stop groove and bond with the concrete structure on both sides of the surface. It can be widely used in newly-built concrete structures with anti-seepage requirements, joint water seals at the junction of new and old concrete, and renovation of old concrete structures.

Description

technical field [0001] The invention relates to a water-stopping structure for structural joints, in particular to a replaceable surface-layer combined water-stopping structure for concrete structural joints. Background technique [0002] Embedded or surface veneer waterstops commonly used in existing concrete structural joints have certain limitations. For example, embedded waterstops require high concrete thickness, which is not conducive to the application of thin-walled structures, and is easy to embed. It conflicts with structural fabric reinforcement, and cannot be replaced after application; veneer waterstops often have poor connection strength, waterproof effect, durability, and ability to adapt to deformation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a replaceable surface-layer combined water-stop structure for concrete structural joints that has good waterproof effect, can be replaced, has strong...
