Abstract
Description
Technical Field
[0001] The present application relates to the technical field of housing construction, and in particular to a highly durable waterproof building exterior deformation joint node structure. Background Art
[0002] Buildings may be deformed due to external factors, such as temperature difference, humidity, etc., especially for large or high-rise buildings. Therefore, deformation joints are needed in the construction process. Deformation joints are the general term for expansion joints, settlement joints and seismic joints. They are used to reduce the possibility of cracking or even damage caused by deformation of buildings under the influence of external factors.
[0003] Expansion joints are formed between building bodies. Commonly used floor expansion joints generally use metal cover plates and waterstops as upper treatment measures for the expansion joints. A metal gutter will be fixed at the bottom of the expansion joint to collect rainwater.
[0004] Regarding the above-mentioned related technologies, metal drainage gutters will generally age and corrode after 2 to 3 years, resulting in water seepage and leakage. Since the leakage of rainwater will cause the indoor environment of the building to deteriorate and even cause damage to the internal structure of the building, there is room for improvement.

[0019] Preferably, a leveling layer is provided on the inner bottom wall of the drainage trough body.
[0020] By adopting the above technical scheme, the setting of the leveling layer protects the structure of the drainage trough body, thereby helping to increase the service life of the drainage trough body; at the same time, the setting of the leveling layer helps to improve the flatness of the bottom wall of the drainage trough body, so as to facilitate the operator to lay the waterproof layer, thereby helping to improve the fit of the waterproof layer to the bottom wall of the drainage trough body.
