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 special-shaped column in the manner of ABB···BBA.

[0057] as attached Figure 4 As shown, in the prestressed eccentrically supported frame system of industrialized assembled special-shaped column steel structure according to 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 s...

Abstract

The invention discloses an industrialized assembling type special-shaped column steel structure prestress eccentric supporting system and belongs to the technical field of structure engineering. The industrialized assembling type special-shaped column steel structure prestress eccentric supporting system comprises an assembling type truss plate, assembling type columns and a prestress eccentric supporting member. The assembling type truss plate comprises a lattice truss beam and a floor plate. The assembling type truss plate is prefabricated in a plant and spliced with beam column joints of the assembling type columns through a beam end sealing plate of the assembling type truss plate at the construction site, and the assembling type columns are spliced to form a multiplayer truss plate steel framework structure among layers through bolts at site. On the basis of the truss plate steel framework structure, the prestress eccentric supporting member serves as a lateral load resistance element to be connected with the bottoms or the tops of the truss beam in the assembling type truss plate and the assembling type columns. The assembling type truss plate, the assembling type columns and the prestress eccentric supporting member are all fabricated in the plant and assembled at the construction site through bolts.

Description

technical field [0001] The invention relates to an industrially assembled special-shaped column steel structure prestressed eccentric support frame 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, my country's steel output exceeded 700 million tons in 2011, 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 ...
