Embodiment Construction

[0055] The present invention is described in detail below in conjunction with accompanying drawing:

[0056] as attached figure 1 As shown, the assembled truss plate of the present invention is spliced ​​with the assembled column in the manner of ABB···BBA.

[0057] as attached Figure 4 As shown, in the industrialized assembled special-shaped column steel structure frame-central support frame system described in the present invention, the involved beams are truss beams composed of channel steel and angle steel splicing, including upper and lower chords 5 and webs 4, wherein the upper and lower The chord 5 is made of channel steel, and the web 4 is made of angle steel, which is divided into single-channel steel beams and double-channel steel beams. The single-channel steel beams are provided with connecting holes at intervals of a fixed distance, so that the two pieces can be bolted together when the plates are spliced. Single-channel steel beams are spliced ​​into double-c...

Abstract

The invention provides an industrialized assembly type special-shaped column steel structure frame-eccentric support system and belongs to the technical field of structural engineering. The industrialized assembly type special-shaped column steel structure frame-eccentric support system comprises assembly type truss plates, assembly type columns and central support members. Each assembly type truss plate comprises lattice truss beams and floor slabs and is prefabricated in a factory, and the assembly type truss plates and beam-column joints of the assembly type columns are spliced through beam-end seal plates in a construction site, and the assembly type columns are spliced among layers in the site through bolts to form a multiple-layer truss plate steel frame structure. Based on the truss plate steel frame structure, the central support members serve as lateral force resisting members and are connected with the truss beams in the assembly type truss plates and the bottoms or the tops of the assembly type columns. The assembly type truss plates, the assembly type columns and the central support members are prefabricated in the factory and are assembled in the construction site through bolts.

Description

technical field [0001] The invention relates to an industrially assembled special-shaped column steel structure frame-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 steel structures for houses (including residences). [0003] At present, the systematic research on high-rise steel structure residences at home and abro...
