Embodiment Construction

[0026] The present invention is described in detail below in conjunction with accompanying drawing:

[0027] as attached figure 1 As shown, in the post-earthquake self-resettable multi-section beam steel frame node of the present invention, the involved special-shaped columns are: L-shaped column 1, T-shaped column 2, and cross-shaped column 3;

[0028] as attached figure 2 As shown in the present invention, the self-resettable multi-section beam steel frame nodes after the earthquake mainly include L-shaped, T-shaped, and cross-shaped nodes. Taking the cross-shaped node as an example, it is split in the figure. The node connection is the connection between the frame column 3 in the middle of the frame and the I-beam 4 at the end. Specific connection steps: The hoisting equipment connects the I-beam 4 at the end and the frame column 3 vertically and closely, and the web angle steel 5 is used as a connecting piece to connect the I-beam 4 at the end with the frame column 3 wi...

Abstract

The invention discloses a post-earthquake self-reset mountable multi-section beam steel frame node. The post-earthquake self-reset mountable multi-section beam steel frame node is characterized in that I steel beams are connected to different forms of special-shaped columns through web angle iron and flange angle iron to form a weldless full-bolt connection mode; middle I-beams and end I-beams areconnected through web connecting plates and high-strength silicone rubber plates to form a weldless full-bolt connection mode with good ductility and high energy consumption performance; and a prestressed steel cable is applied to a weldless full-bolt joint between the each middle I-beam and the each end I-beam to form a pre-stress post-earthquake self-reset node.

Description

technical field [0001] The invention relates to a post-earthquake self-resettable multi-segment beam steel frame node, which belongs to the technical field of earthquake prevention and disaster reduction. Background technique [0002] Multiple earthquakes have proved that the seismic performance of steel structure buildings is greatly improved compared with reinforced concrete buildings, and the difficulty of post-earthquake repairs is greatly reduced. Therefore, vigorously developing steel structure buildings is the only way to improve the quality of residents' housing, especially the structural forms with high technological content should be paid more attention to and developed. [0003] Steel structure prestressing technology has developed rapidly, the most representative of which is the gymnasium of Beijing University of Technology. Innovative research on structural system innovation. However, in the frame structure system, especially the application of prestressing te...
