氯丁橡胶支座GYZ300*74mm我公司专业生产厂家直销

displacement is not restricted, especially suitable for medium, xiao-he load, the displacement of the large bridge.

Plate rubber bearing is highway products which are frequently used in the small and medium-sized Bridges, it is divided into ordinary plate rubber bearing, four fluorine plate rubber bearing. For ordinary bridge bearing is suitable for the span of less than 30 m, displacement smaller Bridges. Different shapes suitable for different bridge span structure, orthogonal Bridges with rectangular pedestal; Curved bridge, skew bridge and columns

GPZ 盆式橡胶支座的工作原理是利用半封闭钢制盆腔内的弹性橡胶块，在三向受力状态下具有流体的性质，来实现上部结构的转动；同时依靠中间钢板上聚四氟乙烯与上座板上的不锈钢板之间的低摩擦系数来实现上部结构的水平位移。从实验的数据来看，橡胶处于三向约束状态时的抗压弹性模量为5*10000千克/平方厘米，比无侧向约束的抗压弹性模量增大近20倍，因而GPZ 盆式橡胶支座承载能力大大提高，解决了普通橡胶支座承载能力的局限。所以GPZ 盆式橡胶支座是能满足大的支承反力，大的水平位移，大的转角要求的新型产品。

  一、GPZ系列盆式橡胶支座的构造特点：
