Problems solved by technology

[0003] For cables that cannot be installed with an external damper, the method of installing a built-in damping rubber ring at the outlet of the embedded pipe is often used; this method uses the extrusion energy consumption of the damping rubber ring to suppress the vibration of the cable, and the material utilization rate Low, the vibration reduction effect is not ideal

Abstract

The invention discloses a shear type rubber damper with a cable fastening device. The shear type rubber damper comprises a cable fastening device, multiple rubber monomer dampers and a connection device, wherein the cable fastening device comprises a cable clamp, a connection bolt, an upper connection plate at the upper end of the cable clamp and a lower connection plate at the bottom of the cable clamp; each rubber monomer damper comprises a high-damping rubber monomer, steel plates at the two ends of the high-damping rubber monomer and connection bolts fixedly connected with the steel plates; the high-damping rubber monomer is connected with the steel plates at the two ends of the high-damping rubber monomer in a vulcanization manner; the connection device comprises upper and lower connection discs; when in use, one end of each rubber monomer damper is connected with a backstay cable embedding pipe fixed on a bridge deck by use of a flange welded on an embedded orifice through the connection device, and the other end is connected with the lower connection plate of the cable fastening device; and the cable clamp of the cable fastening device is fixed on the backstay cable body in a hoop manner. The damper makes full use of the high-damping rubber shear energy consumption performance, has a simple structure and is convenient to mount.

Description

technical field [0001] The invention relates to a bridge structure construction component, in particular to a shock absorber. Background technique [0002] Installing a damper in the cable system is one of the more effective measures to suppress the vibration of the cable; among them, the viscous shear damper and the hydraulic damper are the most used, the technology is mature, and their reliability has been confirmed by engineering applications; but , the viscous shear damper and the hydraulic damper are large in size and high in cost, and most of them are external; since each damper can only provide one axial damping force, a cable generally needs to be installed with two One or more dampers at a certain angle are used to control the vibration of the cables in all directions; since the support requires a large installation space, the setting of the support affects the overall landscape of the bridge, which has great limitations in small and medium bridges. Moreover, the d...
