本标准是对」T/327- 1997<公路桥梁橡胶伸缩装置》的修订。本次修订参考了美国AASHTO(美国
公路桥梁设计规范一LRFD)、德国MAURESOHNE桥梁伸缩装置和瑞士MAGEBA伸缩装置等有关资
料。
本标准与原标准」T/327-1997相比主要变化如下:
—补充了梳齿板式伸缩装置有关内容;
—补充了模数式伸缩装置中采用的压紧支座、承压支座、橡胶位移控制弹簧及聚氨醋位移控制弹
簧的技术指标;
—对伸缩装置中使用的异型钢材提出了基本断面尺寸、每延米重量等具体要求,对钢材材质等级
根据使用条件不同作了区分,以便保证组装后伸缩装置的使用效果。
本标准由中交公路规划设计院提出。
本标准由中华人民共和国交通部科技教育司归口。
本标准起草单位:中交公路规划设计院、河北衡水宝力工程橡胶有限公司、四川新路桥机械有限公
司、交通部公路科学研究所。
本标准主要起草人:郑学珍、鲍卫刚、赵宝勤、刘国建、夏晓霞
本标准 1997年5月首次发布。
