Description

Technical Field

[0001] The utility model relates to the technical field of waterproofing of prefabricated exterior walls of buildings, and in particular to a waterproofing structure of prefabricated exterior walls of assembled buildings. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories are processed and manufactured in engineering, transported to the construction site, and assembled and installed on site through reliable connection methods. When connecting prefabricated exterior wall panels, the joints must be waterproofed to prevent rainwater from seeping into the room along the joints of the exterior wall panels.

[0003] However, during the on-site assembly of prefabricated exterior wall panels, the joints must be waterproofed to prevent rainwater from seeping into the room along the connection nodes of the exterior wall panels. If the water seepage is serious, the connection parts will become loose, and long-term use will lead to a decrease in the effective load-bearing capacity of the prefabricated exterior wall, which will bring major engineering risks. Traditional exterior wall panels are usually waterproofed by applying waterproof glue at the joints. Not only is the construction workload large, but the waterproof glue will age over time, eventually leading to water leakage, affecting the waterproof performance and construction quality of prefabricated buildings.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
