Description
Technical Field
The invention belongs to the technical field of bridge expansion and contraction, and particularly relates to an oblique multidirectional displacement expansion device.
Background
The expansion device is needed to be used on the bridge to meet the expansion requirement of the bridge. The expansion device is a key part in the bridge member and plays an important role in realizing the bridge function. The common bridge expansion device comprises a plate-type rubber expansion device, a section steel modulus expansion device, a comb plate-type expansion device and the like. The bridge can be subjected to the actions of vehicle load, shrinkage and creep of the bridge self material, foundation settlement, wind load and the like in the construction and operation processes, so that the bridge beam end is deformed.
The telescopic device used at present can only meet the requirement of telescopic adjustment in the horizontal direction, and cannot meet the requirement of dislocation deformation in the vertical direction; when passing through the expansion joint, the vehicle can generate vibration noise due to vertical dislocation, and more serious, the bridge beam body is damaged due to the fact that the expansion joint cannot be maintained or replaced. The bridge structural joints have different degrees of spatial movement in the direction of the degree of freedom, so that the expansion device arranged at the bridge beam end is subjected to spatial movement such as extrusion, stretching, torsion, dislocation, sedimentation and the like.
The existing profile steel modular expansion device in the current market has the defects of large longitudinal expansion gap, uneven expansion, concentrated impact force, serious jump, fragile concrete, high expansion part damage rate, high manufacturing cost, deep design reservation groove depth and the like. In particular to a suspension bridge, a cable-stayed bridge and an inclined and bent bridge, because the bridge structure inevitably has multi-directional displacement, the defects of inadaptation to the requirements of transverse and multi-directional displacement are seriously exposed in the use process. The requirements on vertical deformation are high, and the requirements on multidirectional deflection of a bridge modulus type expansion device are difficult to meet for cable-stayed bridges, suspension bridges and the like with large longitudinal deflection and transverse deflection. The conventional comb plate expansion joint can not meet the requirement of the vertical corner of the bridge body.
