Description
Technical field
The present invention relates to a kind of macromolecular elastomer shrinkage joint, can meet road surface, bridge deformation as shrinkage joint, be applicable to, in road, bridge, construction of tunnel, belong to building field.
Background technology
For meeting the requirement of bridge and road distortion, conventionally between two beam-ends, shrinkage joint is set between beam-ends and abutment or in the articulated position of bridge.Bridge expansion joint installation is constructed weak position owing to being arranged on beam-ends, directly bear the repeated action of vehicular load, be exposed in the Nature again more, be subject to the impact of various natural causes, therefore, stretching device is fragile, difficult position of repairing, large bridge Common Steels shrinkage joint in the past, but when the bending of beam body, torsion, fragile, therefore need the New Type Expansion Joint that exploitation can be suitable for multiple load case badly.
Summary of the invention
The object of the invention is the problem existing for prior art, provide a kind of corrosion-resistant, cost is low, can be suitable for the macromolecular elastomer shrinkage joint of multiple load case.
The technical solution used in the present invention is: a kind of macromolecular elastomer shrinkage joint, comprise FX, dilatation region, bolt hole, distortion hole and bolt, described macromolecular elastomer shrinkage joint is installed on rigid pavement by bolt, and flushes with the layer of mating formation; Described FX is provided with bolt hole, establishes distortion hole on described dilatation region.
As preferably, described macromolecular elastomer shrinkage joint is that polyurethane elastomer, rubber or fibre reinforced composites are made, and is preferably polyurethane elastomer.
As preferably, described dilatation region is uniform section or variable cross-section.
As preferably, described distortion hole is rhombus or ellipse.
Beneficial effect: the present invention has lightweight, high-strength, corrosion-resistant, energy free-extension; Smooth-going during Vehicle Driving Cycle, without kick and noise, the advantages such as simple and easy are installed.The present invention is applicable between two beam-ends, between beam-ends and abutment or the articulated position of bridge, meet bridge deformation.
