An industrialized prestressed eccentric support system of column-through-type steel structure frame

Abstract

The invention relates to an industrialized assembly type pillar-running-through steel structure frame prestress eccentric support system, and belongs to the technical field of structural engineering. The industrialized assembly type pillar-cutting-through steel structure frame prestress eccentric support system comprises assembly type truss slabs, assembly type stand columns and prestress eccentric supporting members. Each assembly type truss slab comprises a latticed truss girder provided with an angle bar web member and a floor slab, and the assembly type truss slabs are prefabricated in a factory. At the construction field, the assembly type truss slabs are mutually connected with beam column nodal points in a splicing mode through beam end close plates and cover plates on beams of the assembly type truss slabs. The assembly type stand columns cut through the beam column nodal points, one stand column can run through the height of 4-5 floors, and the stand columns are connected to an inflection point, which is small in stress, in the middle portions of the floors in a splicing mode on site to form multiple layers of truss slab steel frame structures. Based on the truss slab steel frame structures, the prestress eccentric supporting members are connected to the bottoms or the tops of the truss girders in assembly type truss slabs, and the assembly type truss slabs, the assembly type stand columns and the prestress eccentric supporting members are all prefabricated in the factory and assembled through bolts at the construction field.

Description

technical field [0001] The invention relates to a prestressed eccentric support system of an industrialized assembled column through-type 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 a...

Problems solved by technology

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. The industrially assembled steel structure prestressed eccentric support frame system adds lateral and Longitudinal prestressed eccentric cable support increases the lateral stiffness of the structure and improves the deformation performance of the structure
