Abstract

The invention provides a lead-core rubber support component with a friction pair, comprising a lead-core rubber support body, an upper external connecting steel plate and a lower external connecting steel plate which are respectively arranged on the upper end surface and the lower end surface of the lead-core rubber support body, and one-two friction pairs; the upper end surface and the lower endsurface of the support body are respectively connected with the upper external connecting steel plate and the lower external connecting steel plate by a screw and a shearing bond; and one auxiliary surface of each friction pair is respectively arranged on the external upper surface of the upper external connecting steel plate or the lower external surface of the lower external connecting steel plate or arranged at the external upper surface of the upper external connecting steel plate and the lower external surface of the lower external connecting steel plate simultaneously. The installation and use method of the component comprises the steps as follows: the component is arranged between a bridge beam body and a bridge pier; the other auxiliary surface of each friction pair is respectively arranged on the lower surface of the bridge beam and the bridge pier or arranged on the lower surface of the bridge beam and the bridge pier simultaneously; and after creep and shrink of the bridge beam are basically completed, the lead-core rubber support component is fixedly connected with the bridge beam and the bridge pier, thus eliminating the initial deformation of the support caused by the creepage and shrink of the concrete of the bridge beam.

Description

Technical field: [0001] The invention relates to a bridge damping device and an installation method thereof, in particular to a lead rubber bearing assembly and an installation method thereof. Background technique: [0002] The lead core rubber bearing is formed by laminating layers of rubber layers, steel plates, etc. and pouring lead core rods in the middle. The lead core rod increases the damping of the support and absorbs energy; the steel plate increases the vertical stiffness of the support so that it can effectively support the bridge superstructure and building structure; the rubber layer endows the support with high elastic deformation, reset and bearing functions. Therefore, the lead-core anti-seismic rubber bearing not only has high load-carrying capacity, but also has large damping, large horizontal displacement capacity and reset function. It is a shock-absorbing device integrating support and energy consumption; lead-core rubber The bearing can delay the perio...
