Description

Technical Field

[0001] The utility model relates to the technical field of curtain wall joint structures, in particular to a curtain wall expansion joint structure. Background Art

[0002] A building expansion joint is a structural joint that is set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to changes in climate and temperature. After assembly, the curtain wall expansion joint can cooperate with temperature changes to achieve horizontal expansion and contraction between curtain walls. The existing expansion joint structure will reserve an expansion gap between curtain walls, but the sealing performance of this gap structure is poor. During actual use, rainwater can easily penetrate into the interior of the structure from the closed space, thereby corroding the internal connections and affecting the service life of the structure. At the same time, the existing expansion joint structure needs to be installed simultaneously with the curtain wall size during the curtain wall assembly process. The assembly process is complicated and the assembly difficulty is high, which increases the labor intensity of the staff in installing the expansion joint structure. Therefore, it is very necessary to design a curtain wall expansion joint structure. Utility Model Content
