Abstract
The utility model discloses a multi-directionally displaced bridge expansion joint, which comprises a swing tooth plate, a fixed tooth plate and a rubber water-stop belt. The bridge expansion joint is characterized in that the swing tooth plate and the fixed tooth plate are horizontally arranged on a stainless steel plate, a cross-joint plate is arranged at one end of the swing tooth plate, the cross-joint plate, the swing tooth plate and the fixed tooth plate are arranged on a same plane; the cross-joint plate is supported on spherical supports on two sides, the spherical support on one side is fixedly arranged on the swing tooth plate, the rubber water-stop belt is fixedly arranged between the two spherical supports; and the stainless steel plate is movably connected with the swing tooth plate and fixedly connected with the fixed tooth plate. The bridge expansion joint has reasonable structure and solves the raised head phenomenon caused by transverse and longitudinal displacements of the expansion joint due to expansion with heat and contraction with cold of a bridge; compared with the prior art, the bridge expansion joint has the advantages of convenient construction, low maintenance cost, trim expansion joint, more smooth and safer travelling and no noise, so that the bridge expansion joint is more applicable to the bridges with the expansion amount greater than 400mm.
Description
Technical field
The utility model relates to bridge construction, specifically a kind of bridge extension joint of multi-directional deflection.
Background technology
Present bridge generally all adopts the comb shape stretching device, and it has driving steadily, and noise is low, construction and advantage easy to maintenance, and it need be in the repair and replacement of going down of totally-enclosed traffic conditions, and maintenance cost is also lower.But the stretching device of this structure, swing tooth plate directly rests on the bridge floor, it can not adapt to because the vertical or lateral rotation that bridge construction produces, especially use the phenomenon that can produce nose when on the big bridge of stroke, vertically rotating, have a strong impact on safe driving, so it can only use on the bridge of little stroke, regulation can only be used for the following bridge of 200 millimeters strokes in Ministry of Communications's highway standard.Though, developed a kind of " RB (LB) modular multi-directional deflection bridge extension joint " at present, it has been set up on swing tooth plate, and an energy is vertical, the mechanism of lateral rotation, it is to adopt vertical bolt anchoring structure that but this stretching device is connected with bridge, because the anchoring of bolt has limited laterally and vertically rotating of rotating mechanism, and transverse joint plate and swing tooth plate be an integral body, and when vertically rotating, the tooth plate termination can produce very big nose phenomenon.So the comb shape tooth plate stretching device of home and abroad design up to now all can not satisfy vertical rotation, rotate and plane displacement and the raise-free requirement of tooth plate in length and breadth on the plane.
Summary of the invention
The purpose of this utility model is the bridge extension joint of a kind of multi-directional deflection of designing at the deficiencies in the prior art, it adopts the structure of tumbler bearing and transverse joint plate and swing tooth plate split, horizontal, the length travel compensation of stretching device have been realized, can not produce the nose phenomenon because of rotation, the displacement of bridge, construction and maintenance are all very convenient, and good antiskid effect, having improved the safety of driving greatly, noise is low.
The concrete technical scheme that realizes the utility model purpose is:
A kind of bridge extension joint of multi-directional deflection, comprise swing tooth plate, fixed tooth plate, rubber fastening band, characteristics are that swing tooth plate, fixed tooth plate are arranged on the corrosion resistant plate, and an end of swing tooth plate is provided with transverse joint plate, and transverse joint plate, swing tooth plate, fixed tooth plate are a plane; Transverse joint plate is supported on the spherical bearing of both sides, and affixed with spherical bearing, and the spherical bearing of transverse joint plate one side is installed on the swing tooth plate, sets firmly rubber fastening band between two spherical bearings; Corrosion resistant plate and swing tooth plate flexibly connect, and fixedly connected with fixed tooth plate.
The tooth root portion of described swing tooth plate, fixed tooth plate is provided with the scarfing cinder slope.
The utility model is rational in infrastructure, solved that stretching device produces because of bridge expands with heat and contract with cold laterally, the nose phenomenon that causes of length travel, compared with prior art has easy construction, maintenance cost is low, the shrinkage joint is smooth, driving more, safety, noiseless advantage is applicable to that more stroke is greater than 400 millimeters bridge.
