板式橡胶支座的适用范围
Applicable range of plate type rubber bearing
板式橡胶支座是公路中不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.
The plate rubber bearing is one of the most popular products in the highway bridges. It is divided into ordinary rubber bearing and PTFE 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非别与矩形、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 bearing with non rectangular or circular ordinary laminated rubber bearing the same
板式橡胶支座的安装与施工方法
Installation and construction method of plate rubber bearing
板式橡胶支座的安装与施工方法对于板式支座的安装与施工，我们衡水冀通工程橡胶有限公司总结了两种安装方法，第一就是现浇梁安装桥梁公路桥梁板式橡胶支座比较方便，在施工程序如下:保持墩台垫石顶面清洁。如果支承垫石标高差距过大，可以用水泥砂浆进行调整。
The installation and construction method of plate rubber support for the installation and construction of bearing plate, we Hengshui Hebei Engineering Rubber Co., summed up the two installation methods, the first is the installation of cast-in-place beam highway bridge plate rubber bearing is more convenient, in the construction process are as follows: keep the pier pad stone tops clean. If the gap between the supports and stones is too large, the cement mortar can be adjusted.
在支承垫石上按设计图标出中心，安装时橡胶支座的中心与支承垫石中心线要吻合，以确保支座就位准确。当同一片梁需两个或四个支座时，为方便找平，可以在支承垫石和支座之间铺一层水泥砂浆，让支座在桥梁体的压力下自动找平。
On the support pad stone, the center shall be designed according to the design icon, and the center of the rubber bearing shall be in conformity with the center line of the support pad when installing, so as to ensure that the bearing is in correct position. When the same beam needs two or four supports, in order to facilitate leveling, a layer of cement mortar can be laid between the support stone and the support so that the support can automatically level up under the pressure of the bridge body.
在浇注梁体前，在支座上放置一块比支座平面稍大的支承钢 板，钢板上焊接锚固钢筋与梁体连接，并把支承钢板视作浇梁模板的 一部分进行浇注，按以上方法进行，可以使支座与梁底钢板及垫石顶面全部密贴。
In the pouring of beam before placing a slightly larger than the bearing plane of the bearing plate on the support plate, welded anchor bar and beam body connection, and part of the supporting steel plate girder as a template for casting, according to the above method, can make the bearing beam and the bottom steel plate and pad stone tops all. Stick.
预制梁橡胶支座的安装：安装好预制梁橡胶支座的关键在于保证梁底在垫石顶面的平行、平整，使其和支座上、下表面全部密贴，不得出现偏压、脱空和不均匀支承受力现象。施工程序如下：处理好支撑垫石，使支撑垫石标高一致。预制梁与支座接触的底面要保持水平和平整。当有蜂窝浆和倾斜度时，要预先用水泥砂浆捣实、整平。
Prefabricated bridge rubber bearing installation: key pre installed bridge rubber bearing pad stone is to ensure that the top surface of the beam bottom in parallel and smooth, and the support of the upper and lower surfaces all close, there shall be no bias, void and uneven supporting force. Construction procedures are as follows: handle support stone, so that the support pad stone elevation. The bottom surface of the precast beam and the support shall be kept level and smooth. When there is a slurry and tilt, it should be pre - compacted with cement mortar, leveling.
