Expansion joint component

Abstract

The invention provides an expansion joint component. The expansion joint component comprises a first fixed strut member, a second fixed strut member, and an elastic waterproof member, wherein the first fixed strut member is suitable for being fixedly mounted on a building positioned on one side of an expansion joint, and is provided with a first connecting groove of which the opening faces upwards; the second fixed strut member is suitable for being fixedly mounted on a building positioned on the other side of the expansion joint, and is provided with a second connecting groove of which the opening faces upwards; a first connecting bulge and a second connecting bulge are arranged on the back of the elastic waterproof member in a protruding manner; the first connecting bulge is inserted in the first connecting groove and is fixedly connected with the first fixed strut member; the second connecting bulge is inserted in the second connecting groove and is fixedly connected with the second fixed strut member. The expansion joint component disclosed by the invention is simple in structure, and is easy to mount; the elastic waterproof member can well cover the expansion joint, so that water can be prevented from entering the expansion joint; when the elasticity of the elastic waterproof member is lowered, water can only flow into the first connecting groove and / or the second connecting groove from the upward openings and flow out from an opened opening at one end, and the water cannot enter the expansion joint; therefore, the waterproof effect of the expansion joint component is good.

Description

technical field [0001] The invention relates to the technical field of building expansion joint components, in particular to an expansion joint component. Background technique [0002] Construction expansion joints are expansion joints, which refer to a structural joint set at an appropriate part along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion, cold contraction). The expansion joint is to divide the building components above the foundation such as walls, floors, roofs (except wooden roofs) into two independent parts, so that buildings or structures can be horizontally expanded along the long direction. [0003] When the top surface of a building with expansion joints is used as the ground, the expansion joints will separate the ground, so that the ground cannot become a flat plane, which affects the use; and when people move on the top surface of the ...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects of the complex structure of the elastic expansion joint device in the prior art, the poor drainage effect that leads to easy corrosion, and the waterproof rubber pad is not easy to replace, thereby providing a simple structure, waterproof and drainage effect. Good, and elastic waterproof parts easy to replace the expansion joint member
