All-steel structure building and construction method thereof

Abstract

The invention discloses an all-steel structure building, formed by an underground all-steel structure and an overground all-steel structure. The material of steel structural members is low alloy high strength steel Q345B. Also disclosed is a construction method for the all-steel structure building. A reverse building method is used in construction, hoisting of steel columns is completed on a foundation pit, and basement steel beams are constructed and installed in stages. Steel beams of underground first floor and first floor are directly installed on the foundation pit by using a tower crane. Steel beams of underground second floor and third floor are installed layer by layer with a basement earthwork downward underground excavation process. Factory pre-assembly on honeycombed outer frame grid pillar-beam positions in relatively complex structure and core tube steel column supports is performed to ensure on-site installation precision, so as to ensure installation progress. The all-steel structure building is installed in an all-steel structure, and is high in structural strength. A main building lateral load resisting structure system can resist earthquake and wind load.

Description

technical field [0001] The invention relates to an all-steel structure building and a construction method thereof, belonging to the technical field of all-steel structure building construction. Background technique [0002] With the rapid development of my country's domestic economy, it has entered the historical period of building a well-off society in an all-round way. Improving the living standards of residents is an important aspect of building a well-off society. At present, the construction of human settlements in our country is still in the development stage, and more structural forms are adopted, including concrete structure, masonry structure, wood structure and steel structure. In the form of new industrialized roads, the development of steel structure systems is even more advantageous. However, due to the narrow construction site in the bustling road section of the urban area, there is almost no temporary stacking site for steel structural components, and a large...

AI Technical Summary

Problems solved by technology

However, due to the narrow construction site in the bustling road section of the urban area, there is almost no temporary stacking site for steel structural components, and a large number of components cannot enter the site at the same time, which greatly restricts the installation of engineering steel components; during the installation process, the overall installation accuracy is high. The construction process has a relatively large risk. During the construction process, it must be combined with an anti-seismic and wind-resistant system. During construction, special attention should be paid to the occurrence of accidents such as electric shock, poisoning, and tower defense, and safety guarantee measures should be taken.
