Problems solved by technology

[0003] At present, the formwork or deformation joints covered above the expansion joints during construction are relatively lacking in the support of the main structure, and are prone to subsidence after long-term use
In addition, the edge of the concrete is easy to loosen, break and crack after long-term use
In addition, the templates or deformation joints currently installed are generally linear gaps. When the

Abstract

The invention discloses a pre-buried corrugated expansion joint. The pre-buried corrugated expansion joint is used for being pre-buried in a terrace structural joint. The pre-buried corrugated expansion joint comprises a first base and a second base, wherein the first base and the second base are fixedly connected with the two side walls of a structural joint, the first base is connected with a first cover plate, the second base is connected with a second cover plate, a middle cover plate is arranged between the first cover plate and the second cover plate, the upper surfaces of the first cover plate, the second cover plate and the middle cover plate are on the same horizontal plane, the middle cover plate covers the whole structural joint, and a gap between the middle cover plate and thesecond cover plate is in a continuous corrugated shape. The pre-buried corrugated expansion joint is pre-buried in the terrace structural joint and then concrete is poured, so that the pre-buried corrugated expansion joint is good in bearing capacity and not easy to loosen, the edge of the concrete can be protected, and the edge of the concrete is not easy to crack and damage.

Description

technical field [0001] The invention relates to the technical field of industrial building structure design floor expansion joints, in particular to a pre-embedded corrugated expansion joint. Background technique [0002] The floor needs to bear a large load, and requires a certain strength and rigidity, and has the properties of moisture-proof, waterproof, warm-keeping, and wear-resistant. There is a close relationship between the ground floor and the outdoor site of the building. The relationship between the floor and the platform, steps, and the site along the building should be properly handled to make the connection between the building and the site clear and harmonious as a whole. The floor is suitable for some places that require relatively high sanitary conditions, such as the hospital floor, food factory workshop floor, pharmaceutical factory workshop floor, laboratory building floor, machine room floor, etc.; and floors that require stamping, corrosion, and wear re...
