Description

Technical Field

[0001] This invention relates to the field of expansion joint technology in buildings, specifically to an expansion joint structure. Background Technology

[0002] Buildings can experience structural wall deformation due to factors such as temperature differences and settlement. This is especially true for large and high-rise buildings with diverse shapes, heights, and styles, making deformation more complex. During construction, wall expansion joints frequently need to be addressed. To solve deformation problems caused by uneven settlement, earthquake resistance, and temperature in large buildings, expansion joints of a certain width are pre-installed in areas prone to deformation. This effectively breaks down the building, making each section an independent unit. Design codes clearly stipulate the placement of expansion joints, effectively solving problems related to settlement, earthquake resistance, and deformation. However, if these expansion joints are not properly finished, they can not only affect the building's aesthetics but also limit its functionality.

[0003] Based on the production needs of the factory, in order to prevent special situations such as pipe bursts in each layer of chemical solution, avoid leakage of chemical solution from the upper layer to the lower layer, and prevent chemical solution from corroding a larger area, it is necessary to provide a deformation joint structure that prevents corrosion and prevents chemical solution from leaking from the upper layer to the lower layer.
