GYZ橡胶支座350*63mm

GYZ板式橡胶支座是板式支座的一种,它与矩形板式橡胶支座特性基本相同，只是平面形状为圆形，具有剪切变形的同等性，克服了矩形橡胶支座某些遇应力集中的现象，可将上部构造复杂变形和转动经过支座橡胶层的弹性变形来完成。在圆板橡胶支座上用特殊方法粘复一层聚四氟乙烯板（F4），使梁底不锈钢板与F4板之间的自由滑动，完成上部结构较大的位移量,它除了具有矩形橡胶支座的功能外，因其平面圆形在安装时可不考虑其方向性，在弯桥、斜交桥、曲线桥上使用，优点更为明显。

GYZ rubber bearing is a bearing plate, and rectangular plate rubber bearing characteristics are basically the same, but a flat round shape, with the same shear deformation, overcome the rectangular rubber bearing in some stress concentration phenomenon, can be achieved through deformation and rotation bearing rubber layer elastic deformation of complex superstructure. In the plate rubber bearing with special complex method of sticking a layer of Teflon plate (F4), the free sliding between the stainless steel plate and F4 plate beam bottom, complete displacement of upper structure, it has a rectangular rubber bearing function, because of its flat circle in the installation can not consider the direction. In the use of curved bridge, skew bridge, curved bridge, advantage is more obvious.

GYZ板式橡胶支座的安装与施工方法

Installation and construction method of GYZ plate rubber bearing

现浇梁安装桥梁普通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，可以用进行调整。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。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。

The cast-in-place beam installation ordinary bridge plate rubber support in the construction process more convenient, as follows: keep the pier pad stone tops clean. If the height difference between supports and stones is too large, it can be adjusted. The center of the rubber bearing is fitted with the center line of the supporting stone, so as to ensure the correct positioning of the bearing. When the same beam needs two or four support, for the convenience of leveling, can put a layer of cement mortar between bearing pad stone and support, let support automatic leveling of the bridge body under pressure. 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。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. The construction procedure is as follows: handle the supporting stone properly, and make the supporting stone elevation consistent. The bottom of the contact between the precast beam and the bearing should be kept horizontal. When there is honeycomb slurry and slope, cement mortar should be rammed and leveled in advance.
