SSFB系列伸缩装置外形美观，结构简单可靠、使用寿命长、安装、维修方便，具有良好的压缩和拉伸性能。多缝设计选择单元模数为 80mm，伸缩量可根据桥梁实际需要按 80mm 的整数倍选取。单缝伸缩量主要分 40、 60、80 三种型号，分别采用不同结构形式的锚固钢筋适应各种桥梁预留槽口。
The SSFB series expansion joints are featured by simple and reliable structure, long service life, convenient in installation and maintenance, and superior compression and expansion capacities. The unit modulus for multi-joint is 80 mm, and the movement can be selected as per the integral multiple of 80 mm according to the actual need of the bridge. Single cell expansion joint can be classified into three types, including 40, 60 and 80, which use various anchoring bar to suitable for different installation recess of bridges.
SSFB 系列伸缩装置适用于设计荷载为公路 I 级荷载的直桥、弯桥、斜桥、坡桥等各型桥梁。
The SSFB series expansion joint is suitable for various bridges, such as straight bridges, curved bridges, skew bridges and slope, bridges on slope, whose design loads are highway class I load.
