Description

Technical Field

[0002] Building waterproofing is a branch project that ensures that the structure of a building (structure) is not invaded by water and the internal space is not harmed by water. Building waterproofing occupies an important position in the entire construction project. Building waterproofing involves many parts of the building (structure), such as the basement, wall floor, wall body, roof, etc. Its function is to prevent the leakage of rainwater and production and living water and the erosion of groundwater within the design durability of the building or structure, ensure that the building structure and internal space are not polluted, and provide people with a comfortable and safe living space environment. Among them, the waterproofing and thermal insulation of the building's exterior wall is particularly important, which not only affects the living comfort, but also affects the durability of the building.

The key points of its technical solution are that it includes a prefabricated board, the prefabricated board is provided with a connection part at intervals, the connection part is provided with a protrusion, the protrusion is provided with a cast-in-place part, and the protrusions are filled with a thermal insulation part located between the prefabricated board and the cast-in-place part; the connection between the connection part and the prefabricated board is set at two places set at intervals, and the connection between the connection part and the prefabricated board is respectively located on both sides of the connection part and the protrusion. The utility model solves the problem that the maximum shear force that the composite floor slab can withstand is relatively small. However, the rock wool board insulation layer used in the utility model is easy to absorb water, causing the wall to bulge or even fall off, and has low durability. In addition, the utility model lacks enhanced anti-seepage measures, which is not convenient for ensuring the airtight and anti-leakage effect of the wall structure. For this reason, we proposed an optimized structure for waterproof and thermal insulation of building exterior walls, which uses composite insulation boards instead of rock wool boards, and strengthens anti-seepage measures to improve the overall durability and waterproof and thermal insulation effects of the structure.
