Abstract
Provided is a spherical steel bearing capable of unidirectional sliding comprising an upper anchor plate, a bottom basin, a piston member, and a spherical liner plate, wherein the lower end of the piston member is a spherical surface with an inner concave which engages with the spherical surface of the upper end of the spherical liner plate, the lower end face of the spherical liner plate being a plane surface and being arranged on the surface of the bottom of the bottom basin, the upper end of the piston member and the lower end of the upper anchor plate being connected by a straight guide rail and a chute which engage with each other. The utility model has the advantages of small structure, light weight, and high cost performance. The design of the straight guide rail and the chute between the upper end of the piston member and the lower end of the upper anchor plate enables the bearing to slide laterally, and the spherical surface engagement between the lower end face of the piston member and the upper end of the spherical liner plate permits a more flexible rotation.
Description
Technical field
The utility model relates to the bridge engineering parts, relates in particular to a kind of unidirectional slip ball shaped steel bearing that is used between bridge beam body and the bridge pier.
Background technology
Ball shaped steel bearing is contemporary bridge design, build requisite engineering part.Present domestic bearing is made up of last anchor plate, base plate, piston piece and spherical crown liner plate usually.During unidirectional sliding-type spherical bearing horizontal slip, last anchor plate plays the effect of gathering sill, form a pair of horizontal slip friction pair between last anchor plate and the base plate, when there is certain corner in the beam body, last anchor plate and base plate relatively rotate, and form a pair of pivoting friction pair, and therefore going up and promptly need slide between anchor plate and the base plate and need rotate, stress is complicated.
Between the application proposed, China Intellectual Property Office disclosed a kind of name and has been called " sliding-type ball shaped steel bearing " utility model patent, and the patent No. is 200820066840.8.This patent is arranged on the horizontal slip parts on the base plate, can increase the horizontal dimension of bearing like this, increases cost.
The utility model content
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to propose the unidirectional slip ball shaped steel bearing that a kind of bearing overall structure is little, reduce cost, making it can improve installation effectiveness and installation accuracy.
The utility model adopts following technical scheme for achieving the above object: a kind of unidirectional slip ball shaped steel bearing, comprise anchor plate, end basin, piston piece and spherical crown liner plate, described piston piece lower end is interior concave spherical surface, cooperate with the sphere of spherical crown liner plate upper end, spherical crown liner plate lower surface is the plane, be positioned at the bottom of the end basin basin on the inner surface, be connected with chute by the line slideway that cooperatively interacts between the upper end that it is characterized in that described piston piece and the last anchor plate lower end.
In such scheme, between the upper surface of described piston piece and the last anchor plate lower surface except that line slideway and chute remainder be corresponding contact plane, be provided with wearing plate between the contact plane of two correspondences.
Furtherly, described wearing plate is embedded in the upper surface groove of piston piece.
In such scheme, be provided with wearing plate between the inner surface at the bottom of spherical crown liner plate lower surface and the end basin basin.
In such scheme, described line slideway is fixed in the upper surface of piston piece, and chute is arranged at the anchor plate lower surface, and line slideway is a rectangular guideway.
In such scheme, described line slideway is positioned at the piston piece centre position.
The utility model bearing adopts unique line slideway that is positioned at centre position, piston piece upper surface and chute structure, and plane of rotation is separated with slide plane, and it is stressed to improve support part inside.
Upward anchor plate of the present utility model and end basin are separately fixed on the anchorage rod iron that is embedded in bridge and the bridge pier concrete, are used for fixing bearing and transmit horizontal force.The external force of the utility model horizontal direction is directly passed to end basin by piston.
The utility model bearing overall structure is little, light weight, cost performance height, especially line slideway and the chute that is provided with between the upper end of piston piece and the last anchor plate lower end, make the bearing can be along horizontal slip, the piston piece lower surface with spherical crown liner plate upper end between sphere cooperate, make its rotation more flexible.This bearing overall structure is little, the processing assembling is also convenient, is convenient to produce in enormous quantities.
