Abstract
Description
Technical Field
[0001] This utility model specifically relates to a building exterior wall structure. Background Art
[0002] In recent years, the requirements for new materials and processes such as exterior wall tiles and exterior wall coatings have gradually entered the stage of large-scale application in construction. Various safety and quality accidents involving the detachment of building exterior walls and large-scale damage to insulation layers have occurred in various places. Each time, it is during extreme weather, when strong winds crack large areas of the wall, causing sections of the wall to be torn off by the wind, creating significant safety hazards.
[0003] Another significant drawback is that cracks between the primary concrete frame structure and the secondary masonry wall structure can lead to substantial water leakage in the exterior walls, resulting in numerous resident complaints. Currently, the industry often uses methods such as covering the cracks or applying waterproof coatings, but these methods fail to address the root cause, leading to water seepage from both the exterior wall cracks and structural cracks.
