摘要
双曲面钢支座是一种适应实际桥梁纵桥向、横桥向两个方向不同转动要求的铁路桥梁钢支座,其具有结构受力合理、使用功能完善、耐久性好等特点。凭借此优点,双曲面支座已应用于多条铁路桥梁工程中。简要介绍了SQMZ型双曲面支座的构造特点、工作原理、设计参数、结构检算及支座试验情况。
Hyperboloidal steel bearing is a kind of railway bridge bearing which can adapt both longitudinal and transverse rotational requirements.It has characteristics such as reasonable force structure,perfect functions and good durability.With its advantages,SQMZ-type hyperboloidal bearings have been widely used in many railway bridge structures.This paper introduces the structure characteristics,working principles,series of design parameters,structure calculation and the experiment of SQMZ-type hyperboloidal bearing.
