产品介绍：
Product introduction:
GJZ桥梁板式橡胶支座是由若干层橡胶片与薄钢板经加压硫化而成与薄钢板镶嵌、粘合、硫化而成一种桥梁支座产品。本产品有足够的竖向刚度以承受垂直荷载，且能将上部构造的压力可靠地传递给墩台；有良好的弹性以适应梁端的转动；有较大的剪切变形以满足上部构造的水平位移；具有构造简单、安装方便、节省钢材、价格低廉、养护简便、易于更换等特点。按形状划分：矩形板式支座、圆形板式支座、球冠板式支座、圆板坡形板式支座。由于板式支座本身具有足够的竖向刚度，可以满足较大垂直荷载，并具有良好的弹性以适应梁端的转动。还具有较大的剪切变形以满足上部构造的水平位移；可以产生很好的防震作用，能减轻动载对上部构造与墩台的冲击作用。
GJZ bridge plate rubber bearing is a kind of bridge bearing product, which is made of several layers of rubber sheet and thin steel plate by pressure vulcanization and inlaid, adhered and vulcanized with thin steel plate. This product has enough vertical stiffness to bear vertical load, and the upper structure of the pressure can be reliably transferred to the pier; have good flexibility to adapt to the rotation of the beam end; to meet the horizontal displacement of superstructure of large shear debation; has the advantages of simple structure, convenient installation, saving steel, low price, easy maintenance, easy replacement. According to the shape classification: rectangular plate bearing, circular plate bearing, spherical bearing plate, plate sloping plate bearing. Because the plate bearing itself has enough vertical stiffness, it can meet the larger vertical load and has good elasticity to adapt to the rotation of the end of the beam. Also has to meet the horizontal displacement of superstructure of large shear debation; earthquake can produce good effect, can reduce the dynamic load impact on the superstructure and the pier.

如果我们在普通板式橡胶支座表面粘复一层1.5mm-3mm厚的聚四氟乙烯板,就能制作成聚四氟乙烯滑板式橡胶支座它除了竖向钢度与弹性变形,能承受垂直荷载及适应梁端转动外,因聚四氟乙烯板的低摩擦系数,可使梁端在四氟板表面自由滑动,水平位移不受限制,特别适宜中、小荷载,大位移量的桥梁使用。由于板式橡胶支座具有水平剪切的各向同性，能良好传递上部构造多的变形。在弯、斜桥的使用中优点突出。该产品除具有普通支座的功能外，还具有在梁端作用力作用时通过球形表面橡胶层调整受力中心的位置，逐渐将力扩散到圆板式橡胶支座的钢板和橡胶层，使支座受力均匀，尤其适用于斜交桥，立交桥等坡度桥的场所。
If we study the PTFE layer of 1.5mm-3mm thick in the ordinary laminated rubber bearing surface, can be made of PTFE sliding plate rubber support in addition to its vertical stiffness and elastic debation under vertical load and can adapt to the rotation of the outer end of the beam, due to the low friction coefficient of PTFE plate, the beam end in PTFE the surface free sliding, horizontal displacement is not restricted, especially suitable for medium and small load, large displacement bridge use. Because the plate rubber bearing has the isotropy of horizontal shear, it can transfer the debation of superstructure much better. The outstanding advantages in the use of curved and skew bridge in. The product not only has the common support function, also has the force at the end of the beam through the spherical surface of the rubber layer to adjust the force center b, will gradually spread to the force of circular plate type rubber bearing plate and the rubber layer, make the bearing force unib, especially suitable for skew bridge, overpass bridge slope place.
