Civil engineering expansion joint waterproof structure

Abstract

The invention relates to the technical field of civil engineering, and discloses a civil engineering expansion joint waterproof structure. The civil engineering expansion joint waterproof structure comprises an expansion joint formed between a first floor and a second floor, a first connecting box, a second connecting box, a traction mechanism, a telescopic supporting mechanism and a drainage groove, wherein the first connecting box is hinged to the first floor, the second connecting box is partially sleeved with the first connecting box, the second connecting box is hinged to the second floor, the traction mechanism is connected between the first connecting box and the second connecting box, the lower end of the telescopic supporting mechanism is hinged to the side wall of the first floor or the second floor, the upper end of the telescopic supporting mechanism is hinged to the first connecting box, and the drainage groove is formed in the upper surface of the first connecting box and the upper surface of the second connecting box. The expansion joint waterproof structure can be dynamically adjusted under the condition that the height difference is generated between buildings on the two sides, the two ends of the expansion joint waterproof structure are flush with the buildings on the two sides all the time, and therefore overall connection between the floors and the expansion joint waterproof structure is guaranteed.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a waterproof structure for expansion joints in 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 stretched 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 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...

[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
