Technical Field

[0001] The utility model relates to the technical field of deformation joints, in particular to a waterproof structure used for deformation joints of curtain wall exterior walls. Background Art

[0002] Deformation joints are a general term for expansion joints, settlement joints and seismic joints. Buildings often deform under the influence of external factors, leading to cracks or even damage. Deformation joints are structural joints reserved for this situation. Deformation joints require waterproof structures for waterproofing and shielding.

[0003] The Chinese patent publication number is CN218148976U, and the technical solution disclosed in the patent document is as follows: a stone curtain wall deformation joint connection structure, including a curtain wall, the opposite sides of the curtain wall are connected with L-shaped plates through sealant, and the opposite sides of the L-shaped plates are fixedly connected with U-shaped plates; the inner side walls of the U-shaped plates are fitted with connecting heads, the opposite sides of the connecting heads are fixedly connected with insulation layers, the opposite sides of the connecting heads are fixedly connected with waterproof layers, the side of the connecting heads close to the waterproof layer is fitted with a clamping head, and the bottom top of the clamping head is fixedly connected with a clamping spring; the utility model realizes the rapid disassembly and installation of the insulation layer and the waterproof layer, and the rapid disassembly and installation of the steel plate through the coordinated use of a pull ring, a clamping spring, a clamping head, a plug ring, a plug spring and a plug connector, replacing the traditional form of installation by bolts, so that there is no need to carry a large number of bolts when making connections, reducing the burden on personnel, improving the efficiency of deformation joint connection, and facilitating personnel use.

[0004] Although the above technology is more convenient for disassembly than the traditional bolt installation method, it is inconvenient to limit the pull ring. When installing the waterproof layer, multiple pull rings need to be pulled at the same time, so it requires the cooperation of multiple people, which is time-consuming and laborious.
