Problems solved by technology

Although it is faster than the traditional brick-concrete structure, with the increase in labor costs year by year, this construction method relying on on-site manual assembly is increasingly showing the shortcomings of low construction efficiency. Due to the use of wooden structural panels and foam materials, There are fire hazards and primitive deficiencies such as waterproofing and termite prevention
[0003] Common steel structures can be used to build multi-storey and high-rise buildings. Since common steel structures are mainly H-shaped steel components with large volumes, the building form of enclosure structures with infill walls is often used. It is independent on the inner side of the wall, so that the steel structure is easy to corrode in the air, and it will expand with heat and contract with temperature fluctuations, and linear expansion will occur, which will cause stress damage to the enclosure structure, resulting in local cracks in the enclosure structure, heat preservation and waterproof The performance is damaged, and at the same time, the scary sound produced by the expansion and contraction of the steel structure is often heard. Because the exposed steel parts bring certain difficulties to the interior decoration and occupy a certain building space, the construction efficiency of this kind of filling wall such as aerated block masonry Low, and the external wall insulation system cannot be integrated with the structure, it is easy to crack, and the insulation system fails due to water seepage

Abstract

The invention belongs to the technical field of buildings, and in particular, relates to a steel structure and insulation structure integrated fixed mold shear wall and a construction method. The shear wall comprises a steel structure; an inner fixed template and an outer fixed template are arranged on the inner and outer sides of the steel structure; and space surrounded by the steel structure, the inner fixed template and the outer fixed template is filled with foamed concrete. The shear wall is high and quick in construction efficiency and excellent in overall strength, reduces the defect of oxidation point strength possibly caused by middle broken connection, has such prominent characteristics as convenience to decorate and improvement of the space utilization rate, has the remote construction advantages, is simple and efficient in machining, easy to control the quality, easy to implement all-weather operation construction, excellent in water resistance, fire resistance, earthquakeresisting safety, hurricane resistance and insect resistance, free of obstacles in the space and high in space utilization rate, realizes integration and same life of an insulation structure, and isa wind vane in the future building technology.

Description

technical field [0001] The invention relates to a solid formwork shear wall integrated with a steel structure and a thermal insulation structure and a construction method, belonging to the technical field of construction. Background technique [0002] Whether it is light steel or ordinary steel system, the steel structure housing in our country is basically derived from the technology imported from developed countries, not the original technology of local origin. Steel structure buildings have the characteristics of earthquake resistance, hurricane resistance, high construction efficiency and high waste recycling rate, and have become the main future development trend in the world construction field. Steel structures are divided into light steel structures and ordinary steel structures. Light steel structures are mainly used to build low-rise residential buildings, mostly cold-formed and thin-walled. Multilayer complex. Although it is faster than the traditional brick-conc...
