Industrialized multi-high-rise assembly type steel structure frame-pre-stressed center support system

Abstract

The invention discloses an industrialized multi-high-rise assembly type steel structure frame-pre-stressed center support system, belonging to the technical field of structural engineering, and comprising assembly type truss plates, assembly type flange posts and pre-stressed center support members, wherein the assembly type truss plates are prefabricated in a factory, and are mutually spliced through beam end sealing plates or post base nodes in a construction field to be used as frame structure beam and slab layers, the frame structure beam and slab layers are up and down connected through the assembly type flange posts to form a multi-layer steel frame structure; on the basis of the steel frame structure, the pre-stressed center support members are connected to the bottoms and the tops of posts or the truss beams in the frame structure beam and slab layers to be used as side force-resisting members; and the pre-stressed center support members are pre-fabricated in the factory, and are assembled by using bolts in the construction field. The invention integrates modularization, industrialization, standardization and assembly, realizes industrialized production and rapid field assembly, and has the advantages of increasing the construction speed, reducing the construction period and lowering the engineering cost under the premise of ensuring the construction quality.

Description

technical field [0001] The invention relates to an industrialized multi-high-rise assembled steel structure frame-prestressed central support system, which belongs to the technical field of structural engineering. Background technique [0002] 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 Iron and Steel Association, in 2011, my country's steel output exceeded 700 million tons, ranking first in the world's steel output for 16 consecutive years. Our country is less than 4%. As the country with the largest construction scale and steel output in the world, China lags behind seriously in the development of housing steel structures. [0003] At present, the systematic research on high-rise steel structure residences at home and abroad is in its infan...

Problems solved by technology

In the traditional steel frame structure system, the lateral rigidity of the structure is difficult to meet the requirements, and the deformation is large, which is easy to cause damage to non-structural components. The industrialized multi-story fabricated steel frame-prestressed central support system adds The lateral and longitudinal prestressed central cable support is used to increase the lateral stiffness of the structure and improve the deformation performance of the structure
