Assembled steel structure prefabricated external wall panel prefabrication and construction method

Abstract

The invention relates to an assembled steel structure prefabricated external wall panel prefabrication and construction method. An insulation board is prefabricated in a concrete prefabricated wall panel; an outer concrete akanthus is arranged on the outer side of the insulation board; an inner concrete akanthus is arranged on the inner side of the insulation board; a floor provided with the concrete prefabricated wall panel is paved with cement mortar, and an embedded part on the top of the concrete prefabricated wall panel and a steel beam are welded into a whole through angle iron; reinforcing steel bars on the left, the right and the top of the concrete prefabricated wall panel and reinforcing steel bars on a post-pouring area are bound, and a whole is formed after concrete is poured;and construction water prevention is carried out on joint parts of the concrete prefabricated wall panel. According to the assembled steel structure prefabricated external wall panel prefabrication and construction method, the post-pasting insulation board is prefabricated in the concrete prefabricated wall panel, the left, the right and the top of the inner akanthus of a member extend to be connected with the reinforcing steel bars, and the bottom is blocked through cement mortar; after the member is arranged and fixed, the reinforcing steel bars on the left, the right and the top of the member are bound with the reinforcing steel bars on the post-pouring area, and the whole is formed after the concrete is poured; and construction is easy and convenient, the maintaining cost is low, and the water leakage hidden danger is eradicated.

Description

technical field [0001] The invention relates to a building construction method, in particular to a prefabrication and construction method of prefabricated steel structure prefabricated exterior wall panels. Background technique [0002] In steel structure buildings, the traditional method of enclosing the external wall is the connection technology of sticking insulation boards after aerated block masonry and light-weight boards are installed. The shrinkage characteristic of the material is relatively large. With the prolongation of the service time, cracks are prone to appear between the material and the steel beam, and water leakage is particularly prone to occur. In recent years, with the popularization and application of prefabricated concrete structures, the external walls generally adopt prefabricated concrete external walls, but the gaps between the external walls are mostly dry-connected, and the gaps between the panels are only filled with water-stop strips and water...

Problems solved by technology

[0002] In steel structure buildings, the traditional method of enclosing the external wall is the connection technology of sticking insulation boards after aerated block masonry and light-weight boards are installed. The shrinkage characteristic is relatively large. With the prolongation of the service time, cracks are prone to appear between the material and the steel beam, and water leakage is especially prone to occur.

In recent years, with the popularization and application of prefabricated concrete structures, the external walls generally adopt prefabricated concrete external walls, but the gaps between the external walls are mostly dry-connected, and the gaps between the panels are only filled with water-stop strips and waterproof sealants. The cost of enclosure during the process is high, and there are hidden dangers of water leakage
