GPZ支座详细参数

GPZ系列(II)行盆式支座GPZ(II)系列盆式支座性能特点GPZ(II)系列盆式橡胶支座是由中交公路规划设计院设计，是原GPZ系列的改进型号，根据交通部JT391—1999《公路桥梁盆式橡胶支座》标准生产的，在原来GPZ系列盆式支座的基础上，作了较大的改进，主要内容为：支座设计承载力允许最大承载力GPZ(II)型支座设计承载力以“MN”为单位，允许超载10%。GPZ型支座设计承载力以“KN”为单位，允许超载5%支座摩擦系数：GPZ(II)型常温型活动支座，在硅脂润滑系数下，设计摩擦系数最小取值为0.03，原GPZ型为0.04。支座转角：GPZ(II)型支座转角为0.02rad(1°08‘)，原GPZ型支座转角为0.01164rad(40‘)。地脚螺栓：为了支座更换方便，地脚螺栓设计上作了改进，地脚螺栓旋入带有内螺纹的底座内，底柱和底板间要垫上厚度不小于2mm的橡胶垫圈，然后一起吊装到位。因此施工预留孔应按底柱直径和长度预留。通常：预留孔直径=底柱直径X3预留柱长度=底柱长度+50(50mm),原GPZ型地脚螺栓直接埋入预留孔内。支座外型尺寸：GPZ(II)型支座平面尺寸均比原设计有所减小，高度有些规格作了调整。密封环：GPZ(II)型支座密封环从结构尺寸和材质上作了改进。经改进后的GPZ(II)型支座设计合理、结构紧凑，巳达国际水平。GPZ系列(II)型盆式支座型号表示方SX—HXXXDX(F)GD」F表示耐寒型,常温型不表示 支座类型 用数字表示竖向承载力'单位MN' 支座名称:公路盆式支座例如:
