Embodiment Construction

[0038] The present invention is described in detail below in conjunction with accompanying drawing:

[0039] as attached figure 1 As shown, in the post-earthquake self-resettable multi-segment beam center prestressed support steel frame of the present invention, the involved special-shaped columns are respectively: L-shaped column 1, T-shaped column 2, and cross-shaped column 3;

[0040] as attached figure 2 As shown in the present invention, the self-resettable multi-segment beam central prestressed support steel frame after the earthquake mainly includes L-shaped, T-shaped, and cross-shaped joints, and the cross-shaped joints are taken as an example to split in the figure. The cross-shaped node connection is the connection between the cross-shaped column 3 and the end I-beam 4 . Specific connection steps: the hoisting equipment makes the end I-beam 4 and the cross-shaped column 3 vertically and closely contacted, and the web angle steel 5 is used as a connecting piece to ...

Abstract

The invention discloses an assembling multi-section beam center prestress support steel frame capable of self-centering after earthquake. An I-beam is connected with special-shaped columns of different forms through a web angle steel and a flange angle steel to form a connecting form of full bolts without weld seams; a middle I-beam is connected with an end I-beam through a web connecting plate and a high-strength silicone rubber plate to form a connecting form of full bolts without weld seams with good ductility and high energy consumption; a prestressed steel cable is applied at the connecting part of the full bolts without the weld seams of the middle I-beam and the end I-beam to form self-centering nodes after the prestressed earthquake, and after the nodes are connected in sequence, aprecast concrete-profiled steel plate composite slab or a poured concrete slab assembling prestress center support member is assembled to form an assembling multi-section beam center prestress support steel frame structure system capable of self-centering after the earthquake.

Description

technical field [0001] The invention relates to a post-earthquake self-resettable multi-segment beam central prestressed support steel frame, which belongs to the technical field of earthquake prevention and disaster reduction. Background technique [0002] Japan's steel structure houses account for more than 60% of all houses. Multiple earthquakes have proved that steel structure buildings have greatly improved seismic performance compared to reinforced concrete buildings, and the difficulty of post-earthquake repairs has been greatly reduced. Therefore, my country's vigorous development of steel structure buildings is the only way to improve the quality of residential housing in our country, especially the form of steel structure with high technological content should be paid more attention to and developed. [0003] my country's steel structure prestressing technology has developed rapidly, and the most representative one is the Beijing University of Technology Gymnasium....
