Description

Technical Field

[0001] This invention belongs to the field of curtain wall waterproofing technology, and specifically relates to a flexible sealing and waterproofing system for suspended curtain walls and its construction method. Background Technology

[0002] During curtain wall construction, the upper part of the vertical frame of a suspended curtain wall is usually fixed to the structure with bolts, while the lower part of the vertical frame can expand and contract axially. In order to meet the material deformation requirements caused by the thermal expansion and contraction of steel, there are gaps between the curtain wall vertical frame, the curtain wall horizontal frame connected to the curtain wall vertical frame, and the structural base plate. In order to avoid curtain wall leakage, the gaps are generally filled with rigid waterproofing or directly with concrete. However, this construction method cannot solve the fundamental problem, and there is still a large risk of leakage. It also affects the deformation of steel in the length direction, resulting in poor construction effect.

[0003] Existing technologies lack specific design for waterproofing at the junction of the lower edge of the vertical frame of a suspended curtain wall and the structure. The gaps between the vertical and horizontal frames of the curtain wall and the structure are generally treated with rigid waterproofing. When the vertical frame causes axial displacement of the horizontal frame, the integrity of the waterproofing at the gaps between the vertical and horizontal frames and the structure is difficult to guarantee, and there is a risk of leakage. This application mainly addresses the technical problems of the weak waterproofing at the junction of the lower edge of the vertical frame of a suspended curtain wall and the structure, and realizes the flexible connection between the vertical and horizontal frames of the curtain wall and the indoor and outdoor structures.
