Industrialized assembly type pillar-running-through beam solid-web steel structure frame eccentric support system

Abstract

The invention relates to an industrialized assembly type pillar-running-through beam solid-web steel structure frame eccentric support system, and belongs to the technical field of structural engineering. The structural system is formed by assembly type floor slabs, assembly type stand columns and eccentric supporting members in an assembled mode through bolts. Each assembly type floor slab comprises a section steel beam and a slab, each section steel beam is connected with other section steel beams or other stand columns through a beam end close plate and a cover plate on the beam to form a beam slab steel frame structure, and then each slab is placed on one beam slab steel frame structure and connected with the beam slab steel frame structure to form an assembly type beam slab. The assembly type beam slabs are prefabricated in a factory, at the construction field, the assembly type beam slabs are mutually connected with beam column nodal points in a splicing mode through the beam end close plates and the cover plates on the beams of the assembly type beam slabs, the assembly type stand columns run through the beam column nodal points, and on the basis of multiple layers of beam slab steel frame structures, the eccentric supporting members are connected to the bottoms or the tops of the section steel beams in a frame structure beam slab layer to serve as lateral load resisting members. Field assembly is carried out by complete adoption of the bolts, and a traditional field welding mode and a traditional concrete pouring mode are canceled.

Description

technical field [0001] The invention relates to an eccentric support system of an industrially assembled column-through-beam solid-web steel structure frame, belonging 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 steel structures for houses (including residences). [0003] At present, the systematic research on high-rise steel structure residences at h...

Problems solved by technology

A lot of welding is used in the construction of traditional steel structure residential buildings, the construction speed is slow, and the pollution to the environment is serious. The most important thing is that the quality of the welds is not suitable for control, which seriously affects the safety performance of the building.

[0004] In the traditional steel frame structure system, the lateral rigidity of the structure is difficult to meet the requirements, the deformation is large, and it is easy to cause damage to non-structural components, and the advantages of steel structure housing have not been fully utilized.
