80型桥梁伸缩缝，Q235打造

单组式桥梁伸缩缝简介
Brief introduction of single group bridge expansion joint
单组式桥梁伸缩缝由型钢边梁、鸟形橡胶密封条、锚固钢板、锚固钢筋等三部分构成，横截面成对称型。当桥体膨胀和收缩是，中间鸟形橡胶密封条可以自由伸缩；并起到防水的作用。
The single group bridge expansion joint consists of three parts, the steel side beam, the bird shaped rubber seal, the anchored steel plate and the anchored steel bar, and the cross section is symmetrical. When the bridge expansion and contraction, intermediate bird shaped rubber sealing strip can be freely telescopic; and the waterproof function.
单组式桥梁伸缩缝的特性
Characteristics of single group bridge expansion joint
单组式桥梁伸缩缝中的鸟形橡胶密封条整条采用氯丁或三元乙丙橡胶制作，具有良好的耐老化、耐曲挠性能。适应桥梁梁端水平、横向、竖向变形，伸缩阻力极小。钢质边梁采用优质型钢，锚固板及锚固筋具有良好的机械性能；车辆冲击力，通过锚固构件均衡的传递到梁体上，使用寿命很长。
The bird shaped rubber sealing strip in the single group bridge expansion joint is made of chloroprene or three ethylene propylene rubber. It has good aging resistance and flexural resistance. To adapt to the horizontal, lateral and vertical deformation of bridge beam end, the expansion resistance is very small. The steel side beam has good mechanical properties bying high quality steel, anchor plate and anchor bar. The impact force of vehicle is transferred to the beam body evenly through the anchorageponent, and the service life is very long.
