球冠圆板橡胶支座:球冠圆板橡胶支座是改进后的圆形板式橡胶支座。其中间层橡胶和钢板布置与圆形板式橡胶支座完全相同，而在支座顶面用纯橡胶制成球形表面，球面中心橡胶最大厚度为4－13mm，球面边缘15mm，以适应3％到4％纵横坡下，梁与支座接触面的中心趋于圆形板式橡胶支座的中心。梁端反力通过球面表面橡胶逐渐扩散传至下面几层钢板和橡胶层。在橡胶支座底面加一圈直径D＝2.5mm的半圆形橡胶圆环，支座受力时首先由底部圆环变形压密，调节底面受力状况，以改善或避免支座底面脱空现象的产生，使支座底面受力均匀

　　Spherical plate: plate rubber bearing spherical rubber bearing is improved after the round plate rubber bearing. The middle layer of rubber and steel plate arrangement and circular plate rubber bearing the same, and in the top surface of the spherical surface bearing made of pure rubber, rubber spherical center of the maximum thickness of 4 13mm, spherical edge 15mm, to accommodate 3% to 4% vertical slope, and the bearing contact surface of the beam center tends to circular plate rubber support center. The back force of the end of the beam is spread through the surface of the surface of the spherical surface to the following layers of steel plate and rubber layer. A circular rubber ring with a diameter of D = 2.5mm is added to the bottom of the rubber bearing. When the bearing is loaded, the bottom ring is pressed to compacted the bottom surface to adjust the stress condition of the bottom surface, so as to improve or avoid the phenomenon of voids on the bottom surface of the bearing so as to make the bearing bottom uniformly distributed.

　　Four. Basin rubber bearing

　　盆式橡胶支座的结构原理是安置于密封钢盆中的橡胶块，在三向受力的情况下，而产生的反力，承受桥梁的垂直荷载，同时，利用橡胶的弹性，满足梁端的转动，通过焊接在上座板上的不锈钢板与聚四氟乙烯的自由滑移，完成桥梁上部构造的水平位移。本系列产品具有结构合理，承载能力大，变形小，水平位移量大，转动灵活，并有良好的缓冲性能，是建筑连续式桥梁的支座。

　　The structure principle of rubber support is arranged on the sealing rubber piece of steel in the basin, in three to force under the condition of anti force, vertical load, under the bridge at the same time, the use of rubber elasticity, meet the rotation of the beam end, the stainless steel plate and polytetrafluoroethylene welded on the upper seat board. The free slip, the horizontal displacement of the upper structure of the bridge is completed. This series of products has the advantages of reasonable structure, large carrying capacity, small deformation, large horizontal displacement, flexible rotation and good cushioning performance. It is the support for continuous bridges.

　　Five. Characteristics of basin rubber bearing

　　盆式橡胶支座且具有重量轻，结构紧凑，构造简单，建筑高度低，加工制造方便，节省钢材，降低造价等优点，是适宜于大垮桥梁使用的较理想的支座。常用的有GPZ、GPZ（Ⅱ）、GPZ(KZ)三大类。 GPZ(II)系列支座目前承载力为31个级别，承载力0.8MN-60MN，能满足大型桥梁建造的需要。   GPZ(II)标准系列中，固定支座在各方向和单向活动支座非滑移方向的水平承载力均不小于支座坚向承载力的10%。抗震型支座水平承载力不小于支座坚向承载力的20%。 支座转动角度不小于0.02rad.   加5201硅脂润滑后，常温型活动支座设计摩阻系数最小取0.03.;加5201硅脂润滑后，耐寒型活动支座设计摩阻系数最小取0.06。

　　The basin rubber bearing has the advantages of light weight, compact structure, simple structure, low building height, convenient processing and manufacturing, saving steel and reducing cost. It is an ideal support suitable for the use of big break bridges. There are three commonly used categories: GPZ, GPZ (II) and GPZ (KZ). The bearing capacity of GPZ (II) series is 31 grades at present and the bearing capacity is 0.8MN-60MN, which can meet the needs of large bridge construction. In the GPZ (II) standard series, the horizontal bearing capacity of the fixed bearing in the direction of non slip in all directions and unidirectional bearings is not less than 10% of the bearing capacity of the bearing. The horizontal bearing capacity of the aseismic support is not less than 20% of the support bearing capacity. Bearing rotation angle is not less than 0.02rad. 5201 grease lubrication, normal temperature type movable bearing design minimum friction coefficient 0.03.; add 5201 grease lubrication, cold type movable bearing design friction coefficient minimum 0.06.
