盆式橡胶支座
Basin rubber bearing
水平位移量大、转动灵活等特点，且重量轻，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。本系列支座承载力为31个级别，承载力0.8MN-60MN，能满足大型桥梁建造的需要。
With the advantages of large horizontal displacement and flexible rotation, it 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. The bearing capacity of this series is 31 levels, and the bearing capacity is 0.8MN-60MN. It can meet the needs of large bridge construction.
本标准系列中，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.
In this 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.? Plus 5201 grease lubrication, normal temperature type movable bearing design minimum friction coefficient 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。
Add 5201 grease lubrication, cold type movable bearing design friction coefficient minimum 0.06.
