Problems solved by technology

The existing sliding plate rubber bearing mainly dissipates the energy under the action of the earthquake through sliding friction, its horizontal stiffness is low, the sliding friction is small, the effect of bridge shock absorption and energy dissipation is poor, and the horizontal displacement of the bearing is easily greater than the designed one. Maximum displacement, causing damage to the bearing, thus affecting the safety of the bridge

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0027] Such as figure 1 , figure 2 The embodiment of the damping friction bearing of the present invention is shown. The damping friction bearing is arranged between the main girder of the girder bridge and the bridge pier or abutment, and is used to provide shock-absorbing limit support for the girder bridge, and to a certain extent prevent The possible girder drop phenomenon of continuous girder bridges under the action of large earthquakes. The damping friction support of this embodiment includes an upper seat plate 1 and a lower seat plate 2, the upper seat plate 1 is fixed on the bottom plate of the bridge beam, the lower seat plate 2 is fixed on the pier, and the upper seat plate 1 and the lower seat plate 2 are slidably matched to meet Bridge displacem...

Abstract

The invention provides a damping friction support comprising an upper seat plate and a lower seat plate. The upper seat plate and the lower seat plate are matched in a sliding mode. A pair of transverse damping assemblies and a pair of longitudinal damping assemblies are arranged between the upper seat plate and the lower seat plate. A pair of transverse sliding groove sets and a pair of longitudinal sliding groove sets are arranged on the upper seat plate. The transverse damping assemblies comprise transverse steel damping elements. The upper portions of the transverse damping element are slidably arranged on the transverse sliding groove sets, and the lower portions of the transverse damping elements are fixed on the lower seat plate. The longitudinal damping assemblies comprise longitudinal steel damping elements. The upper portions of the longitudinal steel damping element are slidably arranged on the longitudinal sliding groove sets, and the lower portions of the longitudinal steel damping elements are fixed on the lower seat plate. The damping friction support has the advantages that the safety and seismic resistant performance of the support are improved.

Description

technical field [0001] The invention relates to the field of bridges and building supports, in particular to a damping friction support. Background technique [0002] Under the action of earthquake, the falling beam of the bridge superstructure is one of the main reasons for the collapse of the bridge. In order to ensure the safety of the bridge superstructure under the earthquake, the existing measures are to set up shock isolation between the superstructure and the substructure of the bridge. support. With the acceleration of infrastructure construction and the rapid development of bridge technology, various shock-absorbing and isolating bearings emerge in an endless stream, among which sliding plate rubber bearings are the main ones. [0003] Under the earthquake, the bridge will undergo a large displacement, and the sliding plate rubber bearing used as the upper and lower structural connectors of the bridge is also prone to large horizontal displacements. The existing ...
