An assembled steel structure building composite sandwich wall panel and its installation method

Abstract

The invention discloses an assembled steel structure building composite sandwich wall panel and an installation method thereof, belonging to the technical field of building construction. The device mainly includes a steel frame body, an inner splint, an outer splint, and a thermal insulation sandwich layer; the inner center of the composite sandwich wallboard of the present invention is a thermal insulation sandwich layer, and the two sides are inner splints containing sound-absorbing materials and flame-retardant materials. Compared with the existing concrete wall, the outer plywood is not only easy to transport and simple to install, but also has outstanding advantages in thermal insulation, sound insulation and flame retardancy. The prefabricated composite sandwich wall panels can be used for external walls, It can also be used as an internal partition wall, has wide applicability, does not generate construction waste, and is environmentally friendly; there are multiple focus points inside the entire wall panel of the present invention, through which the external force on the wall panel is dispersed and weakened, And it can weaken the force generated by the earthquake, thereby reducing the damage to the wall, and has excellent seismic performance.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an assembled steel structure building composite sandwich wall panel and an installation method thereof. Background technique [0002] Prefabricated buildings refer to buildings assembled on site using factory prefabricated components. Prefabricated buildings have the advantages of energy saving, sound insulation, fire prevention, and earthquake resistance. They will not crack or turn yellow after long-term use. Prefabricated buildings are generally made of Panels, beams, columns, floors and other components are assembled one by one. Among them, the wall panels used in the prefabricated building include external hanging panels, internal partitions and external wall panels. It can be seen that the prefabricated building-like wall panels are used in a large amount. . [0003] In order to facilitate assembly and transportation, achieve thermal insulation an...

AI Technical Summary

Problems solved by technology

[0004] The existing composite sandwich wall panels have poor sound insulation, flame retardant and seismic performance, which cannot meet the needs of building construction, and the bonding strength between each wall panel is not high, which is likely to cause problems such as wall cracks and water seepage, and increase later maintenance. At the same time, the mechanical strength of the wallboard is not high, it is easy to be damaged by external force, the reliability is low, the installation is inconvenient, and the construction speed of the building is reduced. Therefore, how to obtain a sandwich wallboard with good quality, low cost and easy installation is the basic Technical issues to be resolved in the domain letter
