板式橡胶支座200*200*42价格
板式橡胶支座由多层天然橡胶与薄钢板镶嵌、粘合、硫化而成一种桥梁支座产品。该种类型的橡胶支座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;
The plate rubber bearing is a kind of bridge bearing product, which is inlaid, glued and vulcanized with multilayer natural rubber and thin steel plate. Rubber bearings of this type have 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;
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。
The utility model has the advantages of simple structure, convenient installation, steel saving, low price, simple maintenance and easy replacement.
在板式支座表面粘复一层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。
After the Teflon plate 1.5mm-3mm thick layer on the plate 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 Liang Duan in the PTFE surface free sliding level the displacement is not restricted, especially suitable for medium and small load, large displacement bridge use.
一、矩形(圆形)板式橡胶支座
First, rectangular (circular) plate rubber bearings
(一)性能:本产品由多层橡胶片与薄钢板镶嵌、粘合压制而发。有足够的竖向刚度以承压垂直荷载，能将 上部构造的反力可靠地传递给墩台，有良好的弹性，以适应梁端的转动;又有较大的剪切变形以满足上部 构造的水平位移。
(1) performance: This product is made of laminated rubber sheet and thin steel plate inlaid, bonded and pressed. There are enough vertical stiffness to bearing vertical load, the upper structure of the reverse force can be reliably transferred to the pier, has good flexibility, in order to adapt to the rotation of the beam end; and to meet the horizontal displacement of superstructure of large shear deformation.
板式橡胶支座200*200*42价格
(二)特点:本产品在桥梁建筑、水电工程、房屋抗震设施上已广泛应用，与原用的钢支座相比，有构造 简单，安装方便;节约钢材，价格低廉;养护简便，易于更换等优点，且本品建筑高度低，对桥梁设计与降低造价有益;有良好的隔震作用，可减少活载与地震力对建筑物的冲击作用。
(two) features: This product has been widely used in bridge construction, hydropower projects, housing seismic facilities, compared with the original steel bearing, has simple structure, convenient installation; steel saving, low price; easy maintenance, easy replacement and other advantages, and the low building height, and reduce the cost of bridge design have good beneficial; isolation, live load and seismic force can reduce the impact on the building effect.
二、四氟乙烯滑板板式橡胶支座
Two, tetrafluoroethylene slide plate rubber bearing
(一)特点:本产品是于普通板式橡胶支座上粘接一层厚1.5-3mm的聚四氟乙烯板而成。除具有普通板式橡 胶支座的竖向刚度与弹性变形，能承受垂直荷载及适应梁端转动外，因四氟乙烯与梁底不锈钢板间的低摩擦系数(μ≤0.03)可使桥梁上部构造的水平位移不受限制。
(1) characteristics: the product is made of a thick 1.5-3mm PTFE plate bonded on the ordinary plate rubber bearing. In addition to the vertical with normal rubber bearing stiffness and elastic deformation under vertical load and can adapt to the rotation of the outer end of the beam, because of low coefficient of friction between the steel plate and beam bottom tetrafluoroethylene (U = 0.03) the horizontal displacement of bridge superstructure is not restricted.
板式橡胶支座是公路中小型桥梁中比较常用的产品，它分为普通板式橡胶支座、四氟板式橡胶支座。对于普通型桥梁支座适用于跨度小于30m、位移量较小的桥梁.不同的平面形状适用于不同的桥跨结构,正交桥梁用矩形支座;曲线桥、斜交桥及圆柱墩桥用圆形支座.
Plate rubber bearings are commonly used in small and medium highway bridges. They are divided into ordinary plate rubber bearing and PTFE plate rubber bearing. For the ordinary type of bridge bearing for bridge in a span of less than 30m, small displacement. Different plane shapes for different bridge structure, bridge with orthogonal rectangular bearings; bearing with circular curve bridge, skew bridge and bridge pier.
对于四氟乙烯板式橡胶支座适用于大跨度、多跨连续、简支梁连续板等结构的大位移量桥梁.它还可用作连续梁顶推及T型梁横移中的滑块.矩形、圆形四氟板式橡胶支座的应用分别与矩形、圆形普通板式橡胶支座相同。
For PTFE laminated rubber bearing is suitable for large span and multi span continuous beam, continuous plate structure of the large displacement bridge. It is also used as a continuous beam and T beam traversing the top slider in the rectangular or circular. Application of PTFE laminated rubber bearings with rectangular or circular ordinary laminated rubber bearing the same.
