Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] Such as figure 1 Shown is the schematic diagram of the channel-shaped steel beam of the present invention, in the post-earthquake easily repairable steel special-shaped column frame joint, the beam involved is a double-channel steel beam 1 made of profile steel, and the double-channel steel beam 1 is made of single-channel steel It is spliced ​​with beam end webs at the beam ends.

[0029] as attached Figure 2-4 As shown, in the post-earthquake easily repairable steel special-shaped column frame joints of the present invention, the post-earthquake easy-repairable steel special-shaped column frame joints mainly include L-shaped, T-shaped, and cross-shaped joints. The above three types of joints are listed in the figure The split diagram of the form; the L-shaped node connection is the connection between the L-shaped special-shaped column 7 at the corner of the fram...

Abstract

The invention discloses a special-shaped steel column frame structure joint easy to restore after an earthquake. According to the special-shaped steel column frame structure joint easy to restore after the earthquake, a double-groove steel beam is connected with a special-shaped column through a beam-end sealing plate, so that a welding-line-free full-bolt connecting form is formed; a prestress steel cable is applied to a welding-line-free full-bolt joint, so that the prestress self-reset joint easy to restore after the earthquake is formed. By the adoption of a prestress self-reset joint form, self-reset of the joint after the earthquake is achieved, and restoring cost after the earthquake is greatly reduced; the shock resistance of the joint is improved, and thus the shock resistance of a frame structure system is improved; compared with a traditional steel-structural construction joint, the special-shaped steel column frame structure joint easy to restore after the earthquake has the advantages that the safety performance is high, environmental pollution is light, the number of safety accidents is small, and construction cost is low.

Description

technical field [0001] The invention relates to a steel special-shaped column frame structure node, which belongs to the technical field of earthquake resistance and disaster reduction, and in particular to a steel special-shaped column frame structure node that is easy to repair after an earthquake. Background technique [0002] The collapse of buildings in earthquakes is the main reason that threatens people's lives and causes property losses. The earthquakes in Wenchuan and Ya’an showed that the seismic performance of concrete structures is not good. At present, my country’s steel structures are developing rapidly, especially the prestressed steel structure technology is at the international advanced level. The world record for the largest structural span leads the development of prestressed steel structures. Making full use of the advantages of prestressing technology and applying it to the steel frame joints will improve the seismic performance and self-resetting abilit...
