Spring supporting type bridge expansion joint structure
The spring supporting type bridge expansion joint structure comprises a fixing plate, the outer end of the fixing plate is anchored to a beam body on one side of an expansion joint, and fixing comb teeth are arranged at the inner end of the fixing plate at intervals; telescopic comb teeth are arranged at the inner end of the telescopic plate at intervals, and the telescopic comb teeth and the fixed comb teeth are arranged in a staggered mode at intervals; the first telescopic unit is arranged between the outer end of the telescopic plate and the side wall of the beam body on the other side of the expansion joint; the second telescopic unit is arranged at the outer end bottom of the telescopic plate; the fixing part is arranged at the bottom of the second telescopic unit; the bottom of the second telescopic unit is fixedly connected with the top of the fixing part. The expansion joint has the advantages that horizontal deformation and angle change of the expansion joint are resisted through the first expansion unit; vertical deformation of the expansion joint is resisted through the second expansion unit; and the transverse spring and the vertical spring also have a certain rotation amount, so that the telescopic comb teeth and the fixed comb teeth cannot be bent and warped even if the automobile is rolled for a long time, and the overall service life is greatly prolonged.
本发明公开了一种弹簧支撑式桥梁伸缩缝结构，包括固定板，固定板外端锚固在伸缩缝一侧梁体上，内端为间隔设置的固定梳齿；伸缩板，伸缩板内端为间隔设置的伸缩梳齿，伸缩梳齿与固定梳齿间隔交错设置；第一伸缩单元设置在伸缩板外端与伸缩缝另一侧梁体侧壁之间；第二伸缩单元设置在伸缩板外端底部；固定部设置在第二伸缩单元底部；其中，第二伸缩单元底部与固定部的顶部固连。本发明优点在于通过第一伸缩单元来抵抗伸缩缝水平形变和角变化；通过第二伸缩单元来抵抗伸缩缝的垂直形变；横向弹簧和竖向弹簧还有一定的旋转量，汽车的长期碾压也不会导致伸缩梳齿与固定梳齿发生弯翘，大大提高了整体的使用寿命。
