参数说明：clip_image012、clip_image014为橡胶支座短边长度和长边长度，可参考下文中表格确定；
Parameters: clip_image012 and clip_image014 are the short side length and long side length of the rubber bearing, which can be determined by the table below.
clip_image016为支座中间层橡胶片的厚度。
Clip_image016 is the thickness of the rubber sheet in the middle layer of the support.
（3）钢结构网架橡胶支座，桥梁橡胶支座，网架隔震垫块中间加劲用薄钢板，应采用符合国家标准《碳素结构钢技术条件》（GB/T700-88）规定的Q235钢或符合国家标准《低合金结构钢》（GB/T1591-1994）规定的Q345钢和Q390钢。其屈服点、抗拉强度及厚度的偏差均应符合国家标准《普通碳素结构钢和低合金结构钢薄钢板技术条件》（GB912）的有关规定。
(3) the steel structure truss bridge rubber bearings, rubber bearings, thin steel plate with grid isolation pad intermediate stiffeners, should be used to comply with the national standard "carbon structural steel technical conditions" (GB/T700-88) the provisions of the Q235 steel or conform to the national standard "low alloy structural steel" (GB/ T1591-1994) of Q345 steel and Q390 steel set. The deviation of yield point, tensile strength and thickness should comply with the relevant provisions of the national standard "general carbon structural steel and low alloy structural steel thin plate" (GB912).
薄钢板的厚度不应小于2mm。平面尺寸应比橡胶板每边小5mm。浇注橡胶前，必须对钢板除锈、去油污、清擦干净，并将周边应仔细加工，以防粘结不良和避免产生应力集中。
The thickness of thin steel plate should not be less than 2mm. The plane size should be smaller than 5mm for each side of the rubber plate. Before pouring rubber, it is necessary to remove rust, remove oil, clean clean, and carefully process the surrounding to prevent bad bond and avoid stress concentration.
设计板式橡胶支座时，应按要求计算确定，同时应满足以下的构造要求：
When designing the plate type rubber bearing, it should be calculated and determined according to the requirements, and the following structural requirements should be met.
（1）板式橡胶支座的平面尺寸短边（clip_image012[1]）与长边（clip_image014[1]）之比，一般可在1:1~1:1.5的范围内采用。为便于支座的转动，短边应放置在平行于网架跨度的方向，长边则垂直于网架跨度的方向；同时应根据工程地质条件、抗震设防要求以及网架下部支承情况等，正确选用和合理布置橡胶支座。
(1) the ratio of the plane dimension short edge (clip_image012[1]) to the long side (clip_image014[1]) of the plate rubber bearing can generally be used in the range of 1:1~1:1.5. As for rotating bearing, the short side should be placed in parallel to the grid span direction is perpendicular to the long side of the grid span direction; at the same time should be according to the engineering geological conditions, seismic fortification requirements and grid supporting conditions, the correct selection and reasonable layout of rubber bearings.
（2）钢结构网架橡胶支座，桥梁橡胶支座，网架隔震垫块的总厚度clip_image020应根据网架跨度方向的伸缩量和网架支座转角的要求来确定，一般可在短边长度的1/10~3/10的范围内采用，且不宜小于40mm。为了满足支座的稳定条件，板式橡胶支座中的橡胶层总厚度clip_image022（不包括加劲薄钢板的厚度）不应大于支座短边长度的2/10，即clip_image024。
(2) the steel structure truss bridge rubber bearings, rubber bearings, grid isolation pad should be based on the total thickness of clip_image020 truss span direction expansion amount and rack bearing angle requirements to determine the scope of the general use of length in the short side of the 1/10~3/10, and not less than 40mm. To meet the stability condition of the support, the total thickness of the rubber layer clip_image022 (excluding the thickness of stiffened thin steel plate) in the plate rubber support shall not be greater than the 2/10 of the short side length of the support, that is, clip_image024.
（3）钢结构网架橡胶支座，桥梁橡胶支座，网架隔震垫块中的每层加劲薄钢板的厚度 钢球抗震支座
