Bridge expansion joint
The invention relates to the technical field of bridge facility construction, in particular to a bridge expansion joint. The bridge expansion joint comprises a first support, a second support, a first waterproof piece, a mounting base, a plurality of swing supporting legs, a plurality of telescopic supporting legs and a protective layer. And a gap is formed between the second support and the first support. The mounting base is located in the gap. One end of each swing supporting leg is rotatably connected with the mounting base, and the other end of each swing supporting leg is connected with the first support or the second support. One end of each telescopic supporting leg is connected with the mounting base, and the other end is connected with the first waterproof piece. When a part of position on the first waterproof part is stressed, the force is redistributed through the multiple telescopic supporting legs, the multiple swing supporting legs and the mounting base and is transmitted to the first support and the second support, on one hand, the bearing capacity of the first waterproof part is improved, and abrasion of the connecting positions of the first waterproof part, the first support and the second support is reduced; on the other hand, overload damage to the telescopic supporting leg near the stress position of the first waterproof piece is avoided.
本发明涉及桥梁设施建造技术领域，尤其涉及一种桥梁伸缩缝。桥梁伸缩缝包括：第一支座、第二支座、第一防水件、安装座、多个摆动支腿、多个伸缩支腿和保护层。第二支座与第一支座之间具有缝隙。安装座位于缝隙内。每个摆动支腿的一端与安装座可转动连接，每个摆动支腿的另一端与第一支座或者第二支座连接。每个伸缩支腿的一端与安装座连接，另一端与第一防水件连接。第一防水件上的部分位置受力时，通过多个伸缩支腿、多个摆动支腿和安装座对力进行重新分配，并将力传递至第一支座和第二支座，一方面提高了第一防水件的承载能力，减小第一防水件与第一支座、第二支座连接位置处的磨损，另一方面避免第一防水件受力位置附近的伸缩支腿过载损坏。
