  广州市圆形公路桥梁支座批发代理

  矩形(圆形)式板

  (1)性能:本产品由多层橡胶片与薄钢板镶嵌、粘合在一定压力、一定温度和一定时间内硫化压制而成。有足够的竖向刚度以承压垂直荷载,能将梁板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梁体构造的水平位移。

  (2)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。

  广州市圆形公路桥梁支座批发代理 聚四氟乙烯滑板式

  简称四氟滑板式桥梁支座,本产品是于普通板式橡胶支座上粘接一层厚2-3mm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,跨度>30米的大跨度桥梁、简支梁连续板桥和多跨连续梁桥可作活动支座使用;连续梁顶推、T型梁横移和大型设备滑移可作滑块使用。

  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,以上部构造的水平位移。

  The rubber pad is comed 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 a larger shear deformation capacity in order to meet, the horizontal displacement of superstructure.

  布置

  Arrangement

  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

  The layout of the rubber pad is mainly related to the structure of the bridge. The supports are usually arranged

  时需要考虑以下的基本原则:

  The following basic principles need to be considered:

  (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;

  (1) when the superstructure is a spatial structure, the rubber pad should be able to adapt to the deformation of the bridge in the direction of the bridge (X direction) and the transverse direction (Y direction);

  (2)橡胶垫块必须能可靠的传递垂直和水力;广州市圆形公路桥梁支座批发代理

  (2) rubber pads must be able to reliably transfer vertical and horizontal forces;

  (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;

  (3) the longitudinal displacement, lateral displacement and longitudinal and constant rotation angle caused by the deformation of the beam should be as unconstrained as sible;

  (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;

  (4) when the bridge is located on the flat slope, the fixed rubber cushion block should be located on the front abutment of the main driving direction;

  (5)橡胶垫块宜设置在具有较大垫块反力的地方;

  (5) the rubber pad should be installed in the place where the reaction force is greater than the block;

  秦平自然不会让韩立在一层用饭了,虽然看起来这位主子颇有些意动的样子。二楼的客人不多,只有三四桌人而已。有一桌人,竟然还是三男两桌共饮的样子,实在颇有些惊世骇俗。当韩立踏入此楼时,自然也看了那一桌人两眼,这一看让韩立心里一怔。因为这五人,竟然全都是基础十层以上的炼气期修士,这可有些不寻常了。难得是魔道六宗的人。韩立首先这样想道。这样一来,在修为远逊自己的低阶修士眼中。韩立可就和一个普通凡人,没有什么区别了。,这边请坐。

  (6)在同一桥墩上的几个橡胶垫块应具有相近的转动刚度;

  (6) several rubber pads on the same pier should he similar rotational rigidity;

  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变形。

  In a word, the layout principle of the bridge rubber pad is not only convenient to transfer the counterforce of the support, but also to make the rubber pad fully adapt to the free deformation of the beam.

  安装

  install

  (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平面或平面平行,其平行度的偏差不宜超过2‰。

  (1) before installing the cushion block, the installation ition of the bearing should be measured and checked, and the mounting plane of the bearing should be parallel to the sliding plane or rolling plane of the bearing, and the deviation of parallelism should not exceed 2.

  (2)垫块安装前应对活动支座顶、底板的相对位置进行检查。

  (2) check the relative ition of the top and bottom plate of the movable support before installing the cushion block.

  (3)垫块安装后,和平面应水平,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‰。

  (3) after the cushion block is installed, the rolling and sliding planes should be horizontal, and the slope of the theoretical plane is not greater than 2 per thousand. The center of the upper and lower plates should be in the middle, and the deviation should not be greater than 2 per thousand.

  (4)为垫块安装平整,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。

  (4) in order to ensure the installation and leveling of the cushion block, the 20~50mm hard dry shrinkage mortar cushion should be rammed between the bottom of the support and the top of the professional cushion stone.
