Embodiment 1

[0025] A wooden frame 2 is set outside the raft foundation. The wooden frame 2 is composed of four pieces of wood with a diameter of 150mm. Tenon joints are used between adjacent woods. The protruding length of the tenon of the wood is 35mm. , the circular mortise will rotate and roll under the action of the external seismic force, and dissipate the seismic energy through the rotation. Anti-seismic pads 1 are arranged on the outer edge of the raft foundation. The distance between the anti-seismic pads 1 is 300-400mm. The anti-seismic pads 1 are composed of anti-seismic steel plates 4 and anti-seismic rubber blocks 5. The thickness is 10mm, the thickness of the anti-seismic rubber block 5 is 20mm, and the width and length of the anti-seismic pad 1 are 70mm. The anti-seismic pad 1 transmits the seismic force encountered by the raft to the wooden frame 2, and the elastic deformation of the wooden frame 2 can relieve the bearing force of the raft. During construction, the concret...

Abstract

The invention discloses an anti-seismic strengthening structure of a frame structure building. The anti-seismic strengthening structure of the frame structure building is characterized in that a wood frame is arranged outside a raft foundation, anti-seismic cushion blocks are arranged on the outer edge of the raft foundation, seismic force borne by a raft is transmitted to the wood frame through the anti-seismic cushion blocks, anti-seismic beams are arranged between adjacent frame columns, and damping blocks are arranged in the middles of the anti-seismic beams; and adjacent frame beams are pulled through prestressed structures. The anti-seismic strengthening structure of the frame structure building is good in anti-seismic strengthening effect and has broad application prospects.

Description

technical field [0001] The invention relates to an anti-seismic reinforcement structure, in particular to an anti-seismic reinforcement structure of a frame structure building. Background technique [0002] In the anti-seismic fortification area, some frame structure buildings may meet the requirements in terms of vertical bearing capacity, but the anti-seismic performance cannot meet the requirements. The seismic performance is mainly manifested in the insufficient ductility of the frame columns, the insufficient rigidity of the frame beams, and the insufficient seismic capacity of the foundation. If the anti-seismic performance is not strengthened, then the structure will be damaged when the earthquake occurs. It is the engineering personnel to strengthen the anti-seismic reinforcement of these buildings to improve the ductility, stiffness and strength of the building structure, so that the buildings will not be damaged in the earthquake disaster. problems faced. Conten...
