1、LYQZ系列拉压球型钢支座应用指南中国路桥（集团）新津筑路机械厂1 系列概述LYQZ 系列拉压球型支座是一种基于 QZ 通用系列球型支座，并在其上增设拉力装置的 新型支座。它除有通用系列球型支座的承压、转动、位移等功能外，还有减轻梁端配重和 抵抗因离心力、横向摇摆力、横向风力以及海水波浪力等产生的竖向拉力和横向剪切力等 作用，还能可靠地解决落梁等问题，使梁体的受力和变位更趋稳定，从而延长桥梁的使用 寿命。2 代号说明LYQZ / 支座主位移量（mm） SX:双向活动支座；DX:单向活动支座； GD:固定支座； 承压力/承拉力（kN） 拉压球型支座示例：LYQZ 5000/1000-DX-el0
