Fabricated steel frame outer wall system and construction method thereof

Abstract

Provided are a fabricated steel frame outer wall system and a construction method thereof. The fabricated steel frame outer wall system comprises a steel frame outer wallboard and a heat preservationand decoration integrated horizontal structure. The horizontal structure comprises a steel beam and a steel truss floor board. The upper side of the steel frame outer wallboard is connected with a steel beam through an upper connecting structure, and the lower side of the steel frame outer wallboard is connected with the steel truss floor board through a lower connecting structure. A frame framework opening faces the center of a core material, the four peripheral edges of the steel frame outer wallboard is recessed relative to the surface, a frame framework further comprises a inner side vertical bent plate, a horizontal plate and an outer side vertical bent plate, a set of reinforced steel plates with the height equal to the outer side vertical bent plate is welded to the inner wall of the outer side vertical bent plate at an interval, and horizontal connecting screw rods are welded to the middles of the reinforced steel plates. The connecting screw rods penetrate through the inner side vertical bent plate, external threads are formed in the ends of the inner sides of the connecting screw rods, and the ends of the inner sides of the connecting screw rods are matched with gaskets and nuts. The fabricated steel frame outer wall system is high in standardization degree, high in overall strength, firm and reliable in connecting joint, especially suitable for multilayer and high-rise buildings and capable of achieving volume production in factories, and the labor cost is reduced.

Description

technical field [0001] The invention relates to an assembled exterior wall system, in particular to an assembled steel frame exterior wall system and an installation method thereof. Background technique [0002] Existing prefabricated exterior walls of steel structures mostly use strip panels, which are connected to the main structure through steel plate clips. This type of exterior wall system has the following disadvantages: [0003] 1. The number of plate components is large; 2. There are many joints between the splicing plates; 3. The installation time is relatively long; 4. The plate has no skeleton, and the overall strength of the external wall system is relatively low; 5. There are many wet operations for external wall installation; 6. 1. It is easy to leak at the connection point; 7. It is easy to crack at the seam. Contents of the invention [0004] The purpose of the present invention is to provide a prefabricated steel frame exterior wall system and its constru...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a prefabricated steel frame exterior wall system and its construction method. It is necessary to solve the existing prefabricated exterior wall system with a large number of plate components, many splicing plate seams, relatively long installation time, and lack of panels. The overall strength of the skeleton and exterior wall system is relatively low, there are many wet operations for exterior wall installation, water leakage is easy at the connection points, and the technical problems are easy to crack at the joints
