Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and more specifically relates to a telescopic strip used for the connection between a vertical wall and the ground. Background Art

[0002] During the construction process, cement will shrink or expand due to the influence of temperature and humidity after the concrete solidifies. Especially in the summer, after being exposed to the sun and rain, the cement floor will crack due to the change in temperature difference. Therefore, it is necessary to open expansion joints on the ground to alleviate the shrinkage or expansion of the concrete surface caused by temperature differences and humidity changes. At present, expansion strips are often set in the expansion joints to achieve a better relief function. However, the expansion strip is only a strip with a certain elasticity, and the installation stability is insufficient and the bearing capacity is not clear, which leads to the situation of easy failure; at the same time, the expansion strip is easily affected by the vertical wall and cannot be installed.
