Abstract

The invention relates to a displacement amplification type E-shaped steel damper, a joint and a construction method of the joint, and belongs to the technical field of shock isolation and shock absorption control. The displacement amplification type E-shaped steel damper comprises a first end plate, a second end plate, a first connecting plate, a second connecting plate, a plurality of E-shaped steel with three limbs and a displacement amplification plate with two limbs, the rigidity of the displacement amplification plate is far larger than that of the E-shaped steel, and the E-shaped steel and the displacement amplification plate are arranged in parallel at intervals. Three limbs of the E-shaped steel are opposite to two limbs of the displacement amplification plate, and the upper limbs and the lower limbs of the E-shaped steel are hinged to the upper limbs and the lower limbs of the displacement amplification plate through bolt pins respectively. According to the displacement amplification type E-shaped steel damper, the displacement of the upper limb and the lower limb of the E-shaped steel is amplified according to the lever principle, the plastic deformation of the E-shaped steel is improved, the rapid installation and replaceable performance can be achieved, and rescue work after an earthquake is conveniently carried out.

Description

technical field [0001] The invention relates to a damper, a pier column-tie beam joint using the damper, and a construction method of the pier column-tie beam joint, in particular to a displacement amplifying damper, belonging to the technical field of vibration isolation and shock absorption control. Background technique [0002] my country is located between the Pacific Rim seismic zone and the Eurasian seismic zone, and is easily affected by earthquakes. Once subjected to seismic loads, the damage to bridges and other building structures is devastating. At the same time, there are many mountains and hills in high-intensity areas in my country, and highways and railways often need to cross deep mountains and canyons. Most of the bridges in such areas have the characteristics of high pier column height and relatively large pier length. For double-column high-pier bridges, it is usually necessary to Tie beams are added between the two piers to increase the stability and later...
