钢结构桥梁橡胶垫块价格
橡胶垫块简介：橡胶垫块是由多层橡胶片硫化粘合而成一种普通橡胶支座产品,这种产品具有足够的竖向刚度,能够将支座上部构造的反力可靠的传递给墩台,支座具有良好的弹性,以应对桥梁的梁端的转动；又有较大的剪切变形能力，以满足上部构造的水平位移。
Brief introduction: rubber pad rubber pad is composed of multilayer rubber vulcanization bonding a common rubber bearing products, this product has enough vertical stiffness, can force reliable transfer to the pier upper bearing structure, bearing has good flexibility, rotating beam end in response to the bridge; and the larger shear deformation capacity, to meet the horizontal displacement of superstructure.
橡胶垫块的布置橡胶垫块的布置主要和桥梁的结构形式有关。通常在布置支座 时需要考虑以下的基本原则：（1）上部结构是空间结构时，橡胶垫块应能同时适应桥梁顺桥向（X方向）和横桥向（Y方向）的变形； （2）橡胶垫块必须能可靠的传递垂直和水平反力；（3）橡胶垫块应使由于梁体变形所产生的纵向位移、横向位移和纵、恒向转角应尽可能不受约束； （4）当桥梁位于平坡上，固定橡胶垫块宜设在主要行车方向的前端桥台上； （5）橡胶垫块宜设置在具有较大垫块反力的地方；（6）在同一桥墩上的几个橡胶垫块应具有相近的转动刚度； 总之，桥梁橡胶垫块的布置原则是既要便于传递支座反力，又要使橡胶垫块能充分适应梁体的自由变形橡胶垫块的安装
The arrangement of rubber padding blocks for rubber pads is mainly related to the structure of the bridge. Usually need to consider the following fundamental principles in the arrangement of support: (1) the upper structure is a space structure, a rubber pad should be able to adapt to the bridge along the bridge direction (X direction) and transverse direction (Y direction) of the deformation; (2) the rubber pad must be able to reliably transfer the vertical and horizontal force; (3) rubber pad shall make due to longitudinal displacement, beam deformation, lateral displacement and longitudinal angle constant to should as far as possible without restriction; (4) when the bridge is located in the flat slope, the front abutment fixed rubber pad should be set up in the main driving direction of the rubber pad (5); should be set in place with large block force; (6) a few rubber pad in the same piers should have similar stiffness; in short, layout principles of bridge rubber cushion is both easy to Transfer the back force of the support, and also make the rubber pad fully fit for the installation of the free deformation rubber pad of the beam body.

1）在垫块安装之前应对支座的安装位置进行测量检验，支座安装平面应和支座的滑动平面或滚动平面平行，其平行度的偏差不宜超过2‰。
1) before installing the cushion block, the installation position of the bearing should be measured and checked. The bearing installation plane should be parallel to the sliding plane or rolling plane of the bearing, and the deviation of parallelism should not exceed 2 per thousand.
（2）垫块安装前应对活动支座顶、底板的相对位置进行检查。 （3）垫块安装后，滚动和滑动平面应水平，其与理论平面的斜度不大于2‰。支座上、下板中心应对中，其偏差不大于2‰。（4）为保证垫块安装平整，一般应在支座底面与职称垫石顶面之间，捣筑 20～50mm厚的干硬性无收缩砂浆垫层。
(2) before the pad is installed, the relative position of the top and floor of the movable support should be checked. (3) after the block is installed, the rolling and sliding plane should be horizontal, and the slope of the plane is not more than 2 per thousand with the theoretical plane. The deviation of the upper and lower plate centers is not more than 2 per thousand. (4) in order to ensure the smooth installation of the pad, the dry and hard shrinkage mortar cushion of 20 to 50mm thick should be mashed between the bottom of the support and the top of the title stone.
橡胶止水带是采用天然橡胶与各种 合成橡胶为主要原料，掺加各种助剂及填充料，经塑炼，混炼，压制成型，其品种规格较多，有桥型、山型、P型、R型、U型、Z型、乙型、T型、H型、E型、Q型等。
The rubber sealing strip is made of natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through mixing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, R type, U type, Z type, T type, H type, type, E type and Q type etc..
该止水材料具有良好的弹性，耐磨性、耐老化性和抗撕裂性能，适应变形能力强、防水性能好，温度使用范围-45℃-+60℃。当温度超过+70℃，以及强烈的氧化作用或受油类等有机溶剂侵蚀时，均不得使用该产品该支座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
The sealing material has good elasticity, wear resistance, aging resistance and tear resistance. It has strong deformation capacity and waterproof performance, and its temperature range is -45 -+60 C. When the temperature exceeds +70 DEG C, and strong oxidation by oils or organic solvents such as erosion, shall not only has the common support function of the use of the product also has the support 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 the bearing plate and the rubber layer, make the bearing force uniform, especially suitable for skew bridge, overpass bridge site slope
