A civil engineering expansion joint waterproof structure

Abstract

The invention relates to the technical field of civil engineering, and discloses a waterproof structure for expansion joints in civil engineering, comprising: an expansion joint formed between a first floor slab and a second floor slab, a first connection box, a second connection box, and a traction mechanism , telescopic support mechanism and drainage groove, the first connecting box is hinged with the first floor, the second connecting box is partially sleeved in the first connecting box, the second connecting box is hinged with the second floor, and the traction mechanism is connected to the first connecting box. Between the first connecting box and the second connecting box, the lower end of the telescopic support mechanism is hinged with the side wall of the first floor or the second floor, the upper end is hinged with the first connecting box, and the drainage groove is opened in the first connecting box. and the upper surface of the second connection box. The invention can dynamically adjust the waterproof structure of the expansion joint under the condition that the buildings on both sides have a height difference, so that the two ends are always flush with the buildings on both sides, thereby ensuring the integral connection between the floor slab and the waterproof structure of the expansion joint .

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a waterproof structure for expansion joints of civil engineering. Background technique [0002] The waterproof structure of civil engineering expansion joints is a structure used to seal and waterproof civil engineering expansion joints. It can be extended horizontally in the long direction. [0003] When the expansion joint waterproof structure is installed on the ground floor of the building, the width of the expansion joint will change due to the thermal expansion and contraction of the ground floor. The height difference between the expansion joint waterproof structure and the floor on the higher side is generated. In this case, it is easy to destroy the integral connection between the floor and the expansion joint waterproof structure. Seam waterproof structure failure. SUMMARY OF THE INVENTION [0004] The invention provides a waterproof structure for expansi...

AI Technical Summary

Problems solved by technology

[0003] When the expansion joint waterproof structure is installed on the ground floor of the building, the width of the expansion joint gap will change due to the thermal expansion and cold contraction of the ground floor, but the surface of the ground floor will also cause slight deformation of the floors on both sides of the expansion joint due to uneven heating. The height difference between the waterproof structure of the expansion joint and the floor on the higher side will cause a step. In this case, the integral connection between the floor and the waterproof structure of the expansion joint will be easily damaged, and the connection will be easily broken, causing the expansion joint seam waterproof structure failure
