兴安网架四孔橡胶支座多少钱
网架支座是依据中华人民共和国交通行业标准《球形支座技术条件（GB/T17955-2009）及建筑抗震设计规范（GB50011-2001）钢结构设计规范（GB50017-2003），经详细的静力学、动力学分析研制而成的新型抗震减振钢支座。抗震减振支座结构更加合理，性能更加可靠，使用寿命更长。
Rack bearing is based on technical support conditions of People's Republic of China traffic industry standard "spherical (GB/T17955-2009) and the code for seismic design of buildings (GB50011-2001) code for design of steel structures (GB50017-2003), the static and dynamic analysis model of seismic vibration damping steel bearing rotogravuer. The seismic damping bearing structure is more reasonable, the performance is more reliable, and the service life is longer.网架支座（又名钢结构支座）分为四个类型：GKQZ型钢结构抗震钢球支座、GJQZ型钢结构减震钢球支座、GKGZ型钢结构抗震球型钢支座、GJGZ型钢结构减震球型钢支座。
Rack bearing (aka steel bearing) is divided into four types: GKQZ type steel structure seismic steel ball bearing, ball bearing type GJQZ damping steel structure and GKGZ type seismic steel structure steel ball bearings, GJGZ type damping steel structure steel ball bearing.
该支座包括固定支座（代码为GD）、单向支座（代号为DX）、双向支座（代号为SX）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 bearing comprises a fixed support (code GD), one-way bearings (codenamed DX), bidirectional support (codenamed SX) three types, 22 grades, bearing capacity, the level of the overall strength of vertical pulling force and bearing are better than ordinary bearing has greatly improved. The series of supports adopt elastic damping element. When the horizontal force is large to a certain extent, the damping spring begins to deform elastically to achieve the buffering effect. When the structure rotates, the ball core rotates to release the torque generated by the upper structure. When the earthquake, the rigid and flexible measures to reduce seismic measures happen at the same time, in order to resist the earthquake input energy is huge, so as to ensure the bridge, reasonable structure displacement amplification coefficient decreases with the force of the earthquake, and the structure of unity. The support can withstand 8-11 degree earthquake, and has good seismic and vibration reduction effect on the engineering structure in high intensity earthquake area, especially in the lower earthquake zone.
