Building expansion joint waterproof structure

Abstract

The invention discloses a waterproof structure for building expansion joints, which comprises: an elastic pad fixedly mounted on the expansion joint; a first waterproof component having a first drainage groove and a U-shaped first connecting portion; a second waterproof component, It has a second drainage groove and a U-shaped second connecting part. The structure of the second waterproof member is symmetrical to that of the first waterproof member. The first waterproof member and the second waterproof member pass through the first connecting part and the second waterproof member. The connecting parts are buckled together and fixedly installed on the elastic pad; after the first connecting part and the second connecting part are buckled together, there is a reserved gap between them. The invention can effectively solve the leakage problem caused by factors such as waterproof aging, shrinkage, cracking, and inconsistent foundation settlement coefficients, and solve the technical problem of anti-leakage of expansion joints in building spaces such as toilets, thereby effectively avoiding water leakage and damage in the later stage. A series of problems such as inconvenient maintenance can effectively reduce the cost of maintenance and repair in the later period and ensure the waterproof quality of construction.

Description

technical field [0001] The invention relates to the waterproof technology of building expansion joints, in particular to a waterproof structure of building expansion joints. Background technique [0002] Waterproof construction is an important technology related to engineering safety, social livelihood, environmental protection and building energy conservation. In many construction projects, the waterproofing of expansion joints is still a very difficult task. Among them, water sealing of expansion joints is a very important and easily overlooked issue. Once the expansion joints leak, it is difficult to repair, which often brings huge economic losses. Moreover, once there are quality problems, maintenance is also extremely difficult. [0003] The traditional waterproof construction of expansion joints mainly includes soft wood board dipped in asphalt and asphalt horseshoe grease expansion joints, steel plate expansion joints, comb-shaped steel plate expansion joints, rubber...

AI Technical Summary

Problems solved by technology

However, due to factors such as waterproof aging, shrinkage, cracking, and inconsistent foundation settlement coefficients, it is easy to cause leakage, so that these processes cannot meet the expansion and contraction requirements; at the same time, the traditional waterproof process also has the temperature difference stress deformation of rigid waterproof, flexible waterproof and easy aging Disadvantages of short life and poor penetration resistance
