Abstract

The invention discloses a highway bridge basin-type buffering bracket high in shock absorption property. The highway bridge basin-type buffering bracket high in shock absorption property comprises a bottom basin and a top plate; the bottom basin is provided with a first threaded hole set, a second threaded hole set, a third threaded hole set, a fourth threaded hole set, a fifth threaded hole set, a sixth threaded hole set, a seventh threaded hole set and an eighth threaded hole set; the top plate comprises an upper plate, bosses and anti-collision plates; a stainless steel plate, a Teflon plate, a transition steel plate, an upper offset plate, a lower offset plate, a round pressure plate, a rubber plate, a sealing ring and a buffering pad are arranged between the top plate and the bottom basin; and the bottom basin is provided with eight buffering limit assemblies and four buffering pull rod assemblies. A modular interface is adopted, so that the maintainability of the bracket is improved, the largest displacement in the axial direction and the transverse direction of a bridge is limited, cutting-off bolts are adopted for consuming collision energy, disengagement of the top plate and the Teflon plate is avoided through the buffering pull rod assemblies, heat energy is generated through uneven knurling, energy is consumed, and therefore the service life of the bracket is longer and the use effect of the bracket is better.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a basin-type buffer bearing for highway bridges with high shock absorption. Background technique [0002] Pot-type rubber bearings have the advantages of large bearing capacity, large horizontal displacement, and flexible rotation. It includes two-way movable bearings, one-way movable bearings and fixed bearings. The two-way movable bearing has vertical bearing, vertical rotation and multi-directional sliding performance. The traditional two-way movable basin rubber bearing is composed of bottom basin, rubber plate, sealing ring, middle steel plate, PTFE plate, Composed of stainless steel slide plate and top plate, the top plate and main girder are fixed by anchor bolts, and the bottom basin is fixed by anchor bolts and pier. The existing two-way movable bearing relies on the low friction coefficient between the PTFE plate and the stainless steel slide plate to realize the displ...
