Damper Plates Replaceable Sealed Node Dampers

Abstract

The invention belongs to the field of shock resistance of structures, and particularly relates to a sealing joint damper provided with a replaceable damping plate. The sealing joint damper provided with the replaceable damping plate comprises a composite elastic body, a column end connecting plate and a beam end connecting plate, wherein the column end connecting plate and the beam end connecting plate are fixedly arranged at the two ends of the composite elastic body correspondingly; and the composite elastic body is in an arc shape, the column end connecting plate and the beam end connecting plate are both made of rectangular steel plates, and bolt mounting holes are formed in the peripheries of the rectangular steel plates of the column end connecting plate and the beam end connecting plate correspondingly. By adoption of the sealing joint damper provided with the replaceable damping plate, the problems that an existing damper is completely destroyed after an earthquake and can only be used once, the maintenance cost is high, material waste can be caused easily, and the existing damper fails when used under special conditions and cannot adapt to various environments are solved. After an earthquake, shearing energy-dissipation discs can be replaced by opening a sealing cover plate, the sealing joint damper can be used repeatedly and is low in maintenance cost, materials are unlikely to be wasted, and the sealing joint damper accords with the economical, environment-friendly and sustainable building principle, is small in size, does not occupy to much service space and is low in cost.

Description

technical field [0001] The invention belongs to the field of anti-seismic structures, and in particular relates to a replaceable sealing node damper with a damping plate, which is applied to building nodes in special environments. technical background [0002] my country is located in an earthquake-prone area, and the losses caused by earthquake disasters are heavy. In the past ten years of earthquake damage investigation, it has been found that the frame building structure is prone to column end or node damage during strong earthquakes, that is, during earthquakes, The column ends of each story frame first yielded and appeared plastic hinges, forming a weak layer, resulting in the collapse of the structure. The traditional anti-seismic design method of joints is too passive, mainly relying on increasing the cross-sectional size of columns or increasing the reinforcement of beam-column joints, which is easy to cause waste of materials, and it is difficult to guarantee the con...

AI Technical Summary

Problems solved by technology

[0007] The existing fan-shaped lead elastic corner damping components (such as the authorized announcement numbers are CN101736828B and CN101713226B) have utilized the advantage that the viscoelastic damper can dissipate energy under the action of small deformation, and perform well in earthquake resistance. However, after the earthquake, the damper Will be completely destroyed, one-time use, high maintenance costs, easy to cause waste of materials, does not conform to the principles of economical, environmentally friendly and sustainable construction, is not sealed, and cannot be adapted to a variety of special environments

There is no corresponding recycling at home and abroad, and the damping plate can replace the sealed node damper
