Embodiment Construction

[0029] The present invention is described in detail below in conjunction with accompanying drawing:

[0030] as attached figure 1 As shown, in the post-earthquake self-resetting multi-section beam steel frame of the present invention, the involved special-shaped columns are respectively: the frame corner frame column 1 is the L-shaped column, the frame side frame column 2 is the T-shaped column, and the frame middle Frame column 3 is a cross-shaped column;

[0031] as attached figure 2 As shown, the post-earthquake self-resettable multi-section beam steel frame of the present invention mainly includes L-shaped, T-shaped, and cross-shaped joints. Taking the cross-shaped joint as an example in the figure, the cross-shaped joint is split. The connection is that the frame column 3 in the middle of the frame is connected with the I-beam 4 at the end. Specific connection steps: the hoisting equipment connects the end I-beam 4 with the frame column 3 in the middle of the frame ve...

Abstract

The invention discloses an assembling multi-section beam 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 boltswithout 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, a precast concrete-profiled steel plate composite slab or a poured concrete slab is assembled to form an assembling multi-section beam 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 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, it is necessary to vigorously develop steel structure buildings, especially the steel structure forms with high technological content should be paid more attention and development. [0003] Steel structure prestressing technology has developed rapidly, the most representative of which is the Beijing University of Technology Gymnasium. Innovative research on steel structure system innovation. However, in the frame structure system, especially the app...
