Building expansion joint waterproof structure

Abstract

The invention discloses a building expansion joint waterproof structure comprising an elastic cushion, a first waterproof component and a second waterproof component. The elastic cushion is fixedly installed on an expansion joint. The first waterproof component is provided with a first draining groove and a U-shaped first connecting portion. The second waterproof component is provided with a second draining groove and a U-shaped second connecting portion. The structure of the second waterproof component and the structure of the first waterproof component are symmetrical. The first waterproof component and the second waterproof component are connected in a buckled mode through a first connecting portion and a second connecting portion and fixedly installed on the elastic cushion. After the first connecting portion and the second connecting portion are connected in a buckled mode, a gap is preserved between the first connecting portion and the second connecting portion. By the adoption of the building expansion joint waterproof structure, the problem that leakage is caused due to aging, contracting and cracking of a waterproof structure, inconsistent sedimentation coefficients and other factors can be effectively solved, and the technical purpose of preventing seepage of expansion joints in a bathroom and other building spaces is achieved; in this way, a series of problems such as later-period water leakage and maintenance inconvenience can be effectively avoided, the later-period maintenance cost is effectively reduced, and the construction quality and the waterproof quality are guaranteed.

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
