Description

High and low span roof deformation joint waterproof joints

technical field

The utility model relates to the technical field of waterproofing of deformed joints of building roofs, in particular to a waterproof joint of deformed joints of high and low span roofs.

Background technique

In industrial and civil buildings, affected by factors such as temperature, foundation, and earthquakes, buildings must use vertically divided gaps, namely deformation joints, to ensure their integrity. Deformation joints improve the damage of deformation to buildings, but at the same time, they also bring certain difficulties to the waterproof and leakproof of building roofs. At the intersection of such gaps, it is necessary to consider not only waterproofing, but also roof waterproofing materials that will not be blocked or damaged when the building is displaced or deformed, so as to ensure the stability of the waterproof structure itself. In the traditional structure of high and low span roof deformation joints, 1 thick aluminum gusset plate is used for flooding. When the deformation joint width is greater than 150m, the thickness of the aluminum gusset plate must be thickened. At the same time, in actual engineering, due to the management of the construction site As well as cost control, it cannot be done with an integral aluminum gusset flashing. Therefore, water seepage is more likely to occur later.
