產品介紹：
Product introduction:
GJZ橋梁板式橡膠支座是由若干層橡膠片與薄鋼板經加壓硫化而成與薄鋼板鑲嵌、粘合、硫化而成一種橋梁支座產品。本產品有足夠的豎向剛度以承受垂直荷載，且能將上部構造的壓力可靠地傳遞給墩臺；有良好的彈性以適應梁端的轉動；有較大的剪切變形以滿足上部構造的水平位移；具有構造簡單、安裝方便、節省鋼材、價格低廉、養護簡便、易于更換等特點。按形狀劃分：矩形板式支座、圓形板式支座、球冠板式支座、圓板坡形板式支座。由于板式支座本身具有足夠的豎向剛度，可以滿足較大垂直荷載，并具有良好的彈性以適應梁端的轉動。還具有較大的剪切變形以滿足上部構造的水平位移；可以產生很好的防震作用，能減輕動載對上部構造與墩臺的沖擊作用。
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 deformation; 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 deformation; earthquake can produce good effect, can reduce the dynamic load impact on the superstructure and the pier.

如果我們在普通板式橡膠支座表面粘復一層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膠支座它除了豎向鋼度與彈性變形,能承受垂直荷載及適應梁端轉動外,因聚四氟乙烯板的低摩擦系數,可使梁端在四氟板表面自由滑動,水平位移不受限制,特別適宜中、小荷載,大位移量的橋梁使用。由于板式橡膠支座具有水平剪切的各向同性，能良好傳遞上部構造多的變形。在彎、斜橋的使用中優點突出。該產品除具有普通支座的功能外，還具有在梁端作用力作用時通過球形表面橡膠層調整受力中心的位置，逐漸將力擴散到圓板式橡膠支座的鋼板和橡膠層，使支座受力均勻，尤其適用于斜交橋，立交橋等坡度橋的場所。
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 deformation 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 deformation 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 position, will gradually spread to the force of circular plate type rubber bearing plate and the rubber layer, make the bearing force uniform, especially suitable for skew bridge, overpass bridge slope place.
