Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-situ structure exterior wall insulation integrated construction, in particular to an exterior wall standardized detachable non-insulation hole reserved structure. Background Art

[0002] The high rigidity of the insulation integrated board material allows it to serve as the exterior formwork for cast-in-place structures while maintaining energy-saving and thermal insulation properties. When embedded climbing frames or other fasteners need to be secured to the concrete surface, no soft material can be present between the fasteners and the concrete. Currently, some projects remove the insulation integrated board after the construction of the insulation integrated board and cast-in-place structure is complete, using a secondary removal method to determine the required size. This increases labor costs, pollutes the environment with debris, and results in poor concrete base smoothing, consuming significant time and effort. Utility Model Content
