钢结构网架垫块：包括固定支座、单向、双向三种型式，22个等级，其水平承载力、竖直方向拔力及支座的整体强度均比普通支座有大幅度提高。该系列支座采用弹性减振元件，当水平力大到一定程度后，减振弹簧开始发生弹性变形实现缓冲作用。当结构发生转角时，球芯产生转动，释放上部结构产生的转矩。地震时，刚性抗震措施和柔性减振措施同时发生作用，以抵御巨大的地震输入能量，这样既能保证桥梁上、下结构合理相对位移，减小地震力的放大系数，又使结构保持统一性。该支座可抵御8-11度地震，对高烈度地震区尤其直下型地震区的工程结构有良好的抗震减振作用。
The steel structure spacer block includes three types of fixed support, one way and two-way, and 22 grades. The horizontal bearing capacity, vertical pulling force and the overall strength of the bearing are all larger than those of the ordinary support. This series of support adopts elastic vibration damping element, when the horizontal force is large to a certain degree, the damping spring begins to have elastic deformation to realize the buffering effect. When the structure turns, the core produces rotation and releases the torque produced by the superstructure. Rigid aseismatic measures and flexible damping measures act simultaneously to prevent huge earthquake input energy during earthquake. This ensures both reasonable and relative displacement of the upper and lower structures, reduces the amplification factor of the seismic force, and makes the structure remain uniform. The support can resist the earthquake of 8-11 degrees, and it has good seismic and vibration damping effect on the engineering structure of the high intensity seismic area, especially in the straight down seismic area.
