    • An easy maintainable spherical bearing for a bridge is provided to perform maintenance work for a structure easily by sliding a deck coupling member supporting a sole plate of a bridge deck only from side to side, and then dismantling while minimizing the lifting width of a bridge deck. An easy maintainable spherical bearing for a bridge comprises a support member(10) fixed to the top of a pier, a spherical frictional member(20) coupled to a spherical groove(12) of the support member, a deck coupling member(40) coupled to the base of a bridge deck and placed on the top of the spherical frictional member to make the top located on the base of a sole plate(30) of the bridge deck, and a negative reaction preventive block(50) controlling the displacement of the deck coupling member, wherein a key groove(200) provided with slide guide grooves(220,220a) and cross-shaped hanging grooves(230,230a,240,240a) is formed to the contact surface between the base of the sole plate and the deck coupling member and coupled with many horizontal resistance keys(100) to control a relative motion. The negative reaction preventive block is composed of a pair of fixing blocks(300) projected to the top of the support member, and control blocks(400) adhered and coupled to the outside of the fixing blocks with many bolts(420) and inserted to guide grooves(42) formed on the outside of the deck coupling member to control the displacement of the deck coupling member.
    • 提供了一种用于桥梁的容易维护的球面轴承,以便通过仅从一侧到另一侧滑动支撑桥面板的底板的甲板联接构件,然后在最小化桥面板的提升宽度的同时拆卸来轻松地对结构进行维护工作 。 用于桥梁的易于维护的球面轴承包括固定到墩顶部的支撑构件(10),联接到支撑构件的球形凹槽(12)的球形摩擦构件(20),甲板联接构件(40) 耦合到桥面板的基部并且放置在球面摩擦构件的顶部上以使顶部位于桥面板的底板(30)的基部上,以及负反作用阻挡块(50),其控制位移 ,其中设置有滑动引导槽(220,220a)和十字形悬挂槽(230,230a,240,240a)的键槽(200)形成在底板的底部和底板之间的接触表面 与多个水平阻力键(100)耦合以控制相对运动。 负反作用块由一对突出于支撑构件的顶部的固定块(300)组成,控制块(400)用许多螺栓(420)粘附并固定到固定块的外侧,并插入到 导向槽(42),其形成在甲板联接构件的外侧,以控制甲板联接构件的位移。
