盆式橡胶支座安装注意事项

Notice for installation of basin type rubber bearing

1、建议在墩、台顶面设置支座垫石。

1. It is suggested that the cushion stone should be installed at the top of the pier and abutment.

2、盆式支座安装前应拆箱作全面检查及进行清洁。除去油污，特别是不锈钢与填充聚四氟乙烯板的相对滑移面应用丙酮或酒精仔细擦洗干净，支座其它各件也应擦洗干净，支座内不得涂刷防锈油。

2, pot bearing before installation should make comprehensive inspection and cleaning operations. Remove oil, especially stainless steel and filled PTFE plate relative sliding surface, apply acetone or alcohol carefully scrub, support, other parts should also be scrubbed clean, support shall not be painted antirust oil.

3、支座除标高必须符合设计要求外，为确保支座的使用性能，须三个方向的平面水平。

3. The elevation of the support must meet the design re In order to ensure the performance of the support, the plane level of the three directions must be guaranteed.

4、支座上、下各部件纵横向必须对中，或由于安装时温度与设计温度不同，支座纵向上下各部件错开的距离必须与计算值相等。

4, the upper and lower parts of the support must be vertical or horizontal, or because the installation temperature and design temperature is different, the bearing vertical, upper and lower parts of the staggered distance must be equal to the calculated value.

5、支座中心线与主梁中心线应重合或保持平行。

5, the center line of the support should coincide with the main line of the main beam or keep parallel.

6、连续桥梁实行体系转换时，必须在支座和硫磺水泥浆块之间采取隔热措施，以免损坏填充四氟乙烯板和橡胶块。

6, the implementation of continuous bridge system transformation, we must take measures between the support and the sulfur cement mortar block, so as not to damage the tetrafuoroethylene plate and rubber block.

通常在布置盆式橡胶支座时需要考虑以下的基本原则：

Usually, the following basic principles need to be considered when setting a basin type rubber bearing:

（1）上部结构是空间结构时，支座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 support should be able to adapt to the deformation of the bridge along the direction of the bridge (X direction) and the direction of the transverse direction (Y direction);

（2）支座必须能可靠的传递垂直和水平反力；

(2) the supports must be able to reliably transmit vertical and horizontal reactions;

（3）支座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 vertical rotation angles due to the deformation of the beam should be free of restraint as far as possible;

（4）铁路桥梁通常必须在每联梁体上设置一个固定支座；

(4) the railway bridge must usually have a fixed support on each beam;

（5）当桥梁位于坡道上，固定支座一般应设在下坡方向的桥台上；

(5) when the bridge is on the ramp, the fixed support shall be located on the abutment in the downhill direction;

（6）当桥梁位于平坡上，固定支座宜设在主要行车方向的前端桥台上；

(6) when the bridge is located on the plain slope, the fixed support shall be located on the front abutment of the main driving direction;

（7）固定支座宜设置在具有较大支座反力的地方；

(7) the fixed support shall be located at the place where the counterforce of the larger bearing is located;

（8）在同一桥墩上的几个支座应具有相近的转动刚度；

(8) several supports on the same pier should have similar rotational rigidity;

（9）连续梁可能发生支座沉陷时，应考虑制作高度调整的可能性。

(9) the possibility of height adjustment shall be taken into account when the support of the continuous beam may occur.

盆式橡胶支座的布置原则是既要便于传递支座反力，又要使支座能充分适应梁体的自由变形。

In a word, the layout principle of the basin type rubber bearing is that it is easy to transfer the counterforce of the support, and also to make the bearing fully adapt to the free deformation of the beam.
