Abstract

The invention relates to an aerated concrete composite thermal insulation wall panel system used for prefabricated steel structure buildings, including: aerated concrete composite thermal insulation strips, connecting bolts, supporting parts, tie parts, caulking materials, and wall leveling With the finishing system, the lower end of the aerated concrete composite insulation strip is connected to the lower frame steel beam through connecting bolts and supporting pieces, and the upper end of the aerated concrete composite insulation strip is connected to the upper frame steel beam through connecting bolts and tie pieces. Compared with the prior art, the aerated concrete composite thermal insulation wall panel system of the present invention is provided with a thermal insulation slurry leveling layer on the outside of the aerated concrete composite thermal insulation slab, and the thermal insulation slurry is constructed on site, and the thickness of the slurry layer can be adjusted to meet the requirements of the wall. The requirement of surface leveling solves the problem of many slat joints and complex structure of the slab joints. It can also completely cover the slab joints with caulking materials, which improves the durability of the wall panel system, reduces the production cost of the enterprise, and solves the problem of production The process is complex and difficult to make.

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to an aerated concrete composite thermal insulation wall panel system and a construction method for a prefabricated steel structure building. Background technique [0002] Air-entrained concrete composite thermal insulation wall panels use autoclaved aerated concrete slabs as the base layer, and the outer composite thermal insulation layer and protective layer are prefabricated in the factory. It has the advantages of light weight, simple structure, low cost, energy saving, sound insulation, and good fire resistance. . But the prior art also has the following problems: [0003] 1. The aerated concrete composite thermal insulation wall panel system uses aerated concrete slabs as the base layer of the wall. Due to the limitation of the production technology level, the width of the aerated concrete slab is small, there are many slabs in the wall, and the structure o...

Problems solved by technology

[0003] 1. The aerated concrete composite thermal insulation wall panel system uses aerated concrete slabs as the base layer of the wall. Due to the limitation of the production technology level, the width of the aerated concrete slab is small, there are many slabs in the wall, and the structure of the slabs is complex , Improper handling of the panel joints will cause cold air to penetrate, and there are aging problems in the wall panel caulking and sealing materials, which also affect the durability of the wall panel system

[0004] 2. When the existing aerated concrete composite thermal insulation wallboard is produced in the factory, in order to meet the fire protection requirements, the thickness of the thermal insulation slurry protective layer is usually 40-50mm. Due to the large thickness of the slurry, the slurry drying time is long, causing the wall panel Long production cycle and low production efficiency

In addition, in order to meet the drying requirements of the thermal insulation slurry, a large production site is required, which also increases the production cost

[0005] 3. During the production process of the aerated concrete composite thermal insulation wall panel, embedded parts need to be installed in the base of the aerated concrete slab to meet the connection requirements between the wall panel and the main structure, but the embedded parts should be set in the aerated concrete slab , not only the production process is complicated, but also there will be the problem of offset of embedded parts, which will cause damage to the cutting equipment of the autoclaved aerated concrete slab during the production process
