Description

A modular multi-story prefabricated steel structure system that realizes rigid node connections

technical field

The invention relates to a modular multi-high-rise assembled steel structure system for realizing rigid node connections, belonging to the technical field of structural engineering.

Background technique

my country's annual urban and rural housing area is 2 billion square meters, of which more than 80% are high-energy buildings, and the energy consumption per unit building area in my country is more than twice that of developed countries. According to the statistics of the China Steel Association and the National Bureau of Statistics, in 2013, my country's steel production exceeded 1 billion tons for the first time, reaching 1.06762 billion tons, ranking first in the world's steel production. The steel structure building area in the United States accounts for more than 50% of the total building area. Japan accounts for 80%, while our country is less than 4%. China, as a big steel production country in the world, lags far behind in the development of steel structure housing.

On January 1, 2013, the General Office of the State Council forwarded the "Green Building Action Plan" formulated by the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development with Guobanfa [2013] No. 1. It clearly stated in the important tasks stipulated that: Vigorously develop green building materials and promote the industrialization of construction. Housing, urban and rural construction and other departments are required to speed up the establishment of a standard system for the design, construction, and production of parts to promote industrialization of construction, promote the standardization of structural parts, parts, and components, enrich the types of standard parts, and improve versatility and replaceability. Promote construction systems such as prefabricated steel structures suitable for industrial production, accelerate the development of prefabrication and assembly technologies for construction projects, and improve the integration level of construction industrialization technology. Support the construction of industrialized bases that integrate design, production, and construction, and carry out demonstration and pilot projects of industrialized buildings. Prefabricated steel structure residences can better reflect the essence of green buildings, and the "Green Building Action" provides a major opportunity for the innovation and industrialization of the corresponding system of steel structures in my country.

The problem with the existing modular multi-high-rise fabricated steel structure system in my country lies in the nodes connected by floor slabs and beams and columns. The rigid connection of nodes cannot be realized only by a limited number of high-strength bolts, which is not conducive to the stress of the structure. The splicing form adopted by the invention can effectively realize the rigid connection of the nodes and overcome the shortcomings of the existing system.
