板式橡胶支座200*200*49厂家,辽宁
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;
Thin plate rubber support by layers of natural rubber and steel inlaid, glue, sulfide and become a kind of bridge bearing products. This type of rubber bearing has enough vertical stiffness to withstand vertical load, and the pressure of the upper structure can be reliably transmitted to pier; Good flexibility to adapt to the rotation of beam end; Have larger shear deformation to meet the horizontal displacement of the upper structure;
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。
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。
Has a simple structure, easy installation, saving steel, low cost, easy maintenance, easy to change, etc.
In plate bearing surface sticky after a 1.5 mm - 3 mm thick layer of teflon plate, can be made into ptfe sliding plate rubber support it in addition to the vertical stiffness and elastic deformation, can withstand the vertical load and to adapt to the beam end rotation, due to the low friction coefficient of ptfe plate, can make the beam end in four fluorine board free sliding surface, the horizontal displacement is not restricted, especially suitable for medium, xiao-he load, the displacement of the large bridge.
一、矩形(圆形)板式橡胶支座
(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。
(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。
二、四氟乙烯滑板板式橡胶支座
(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。
A, rectangular plate rubber bearing (round)
(a) performance: this product by multi-layer rubber sheet and sheet steel inlaid, bonding of suppression. Enough vertical stiffness to pressure on the vertical load, the reaction force of the upper structure can be reliably transmitted to pier, good elasticity, to adapt to the rotation of beam end; Have larger shear deformation in order to meet the horizontal displacement of the upper structure.
(2) features: this product is in the bridge construction, water and electricity engineering, building aseismic facilities has been widely used, and the original compared with steel support, has simple structure, convenient installation; Save, steel prices are low; Advantages of easy maintenance, easy to replace, and low building height, the product is good for bridge design and reduce cost; Has good vibration isolation effect, can reduce the seismic forces and the live load effect on the impact of the building.
Second, tetrafluoroethylene slide plate rubber bearing
(a) features: this product is on the ordinary plate rubber support bonding a 1.5 3 mm thick layer of teflon plate. Besides the ordinary plate rubber vertical stiffness and elastic deformation of rubber bearing, can withstand the vertical load and to adapt to the beam end rotation, because of tetrafluoroethylene and low coefficient of friction between the beam bottom of stainless steel plate (mu 0.03 or less) can make the horizontal displacement of the 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.
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。
Plate rubber bearing is highway products which are frequently used in the small and medium-sized Bridges, it is divided into ordinary plate rubber bearing, four fluorine plate rubber bearing. For ordinary bridge bearing is suitable for the span of less than 30 m, displacement smaller Bridges. Different shapes suitable for different bridge span structure, orthogonal Bridges with rectangular pedestal; Curved bridge, skew bridge and columns with circular pier bridge bearings.
For tetrafluoroethylene plate rubber bearing is suitable for large span, the multi-span continuous beam, continuous slab bridge structures such as large displacement. It also can be used as a continuous beam top slider of generalized T beam transverse. Rectangle, round four fluorine plate rubber bearing applications respectively with rectangular, circular ordinary plate rubber bearing the same.
