Abstract
The invention discloses a multidirectional displacement bridge expansion joint device. The device comprises a movable toothed plate, a fixed toothed plate and a water stop tie, and is characterized in that the movable toothed plate and the fixed toothed plate are flatly arranged on a stainless steel plate. One end of the movable toothed plate is provided with a gap plate which is flush with the movable toothed plate and the fixed toothed plate. The gap plate is supported by spherical bearings at two sides. The bearing at one side is fixed on the movable toothed plate. The water stop tie is arranged between the two spherical bearings. The stainless steel plate is movably connected with the movable toothed plate and is fixedly connected with the fixed toothed plate. The bridge expansion joint device has a reasonable structure and avoids head raising resulting from transverse and longitudinal displacement of the expansion joint device caused by expansion and contraction of a bridge. Compared with the prior art, the bridge expansion joint device has the advantages of allowing for smoother running of vehicles, eliminating noise, along with convenient construction, low maintenance cost, flat expansion and contraction joint and safety, and is more suitable for bridges with an expansion amount more than 400 mm.
Description
Technical field
The present invention relates to the bridge construction technical field, 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 bridge extension joint that the objective of the invention is 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 object of the invention 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 present invention 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.
