Large-displacement assembly type damping multidirectional displacement comb-shaped plate bridge expansion device
The invention discloses a large-displacement assembly type damping multidirectional displacement comb-shaped plate bridge expansion device and belongs to the technical field of bridge construction, which comprises a fixed comb plate fixed on a beam body and a movable comb plate fixed on an adjacent beam body, the movable comb plate comprises a fixed plate and a set of movable comb teeth arranged in the width direction of the beam body. Fixed comb teeth and movable comb teeth of the fixed comb plate are arranged in a crossed manner; key points are that: the key points are as follows; a corner reserved seam is reserved between each movable comb tooth and the fixed plate; every two adjacent movable comb teeth are fixedly connected through a connecting plate, a set of metal plates arranged inthe length direction of the beam body are fixed to the portion, located below the movable comb tooth plates, of the beam body, a corner high-damping support is arranged between every two adjacent metal plates, and the fixed plates and the movable comb teeth are fixedly connected with the metal plates located below the fixed plates and the movable comb teeth respectively. When an external force isapplied, the movable comb teeth can generate a vertical corner and a horizontal corner in time, so that vehicles can stably and safely pass through the comb teeth.
本发明公开了一种大位移装配式阻尼多向变位梳型板桥梁伸缩装置，属于桥梁建造技术领域，包括固定在一个梁体上的固定梳齿板、以及固定在相邻梁体上的活动梳齿板，活动梳齿板包括固定板、以及一组沿梁体宽度方向排列的活动梳齿，固定梳齿板的固定梳齿与活动梳齿交叉设置，关键在于：每个活动梳齿与固定板之间都留有转角预留缝，相邻的活动梳齿之间借助连接板固定连接，位于活动梳齿板下方的梁体上固定有一组沿梁体长度方向排列的金属板，相邻金属板之间设置有转角高阻尼支座，固定板、活动梳齿分别与位于其下方的金属板固定连接。当有外力作用时，活动梳齿可以及时产生竖向转角和水平转角，使车辆能够平稳、安全地通过。
