橡胶支座 Rubber bearing 橡胶支座是指用以支承容器或设备的重量,并使其固定于一定位置的支承部件,还要承受操作时的振动与地震载荷。橡胶支座是橡胶和薄钢板紧密结合而成,用于支撑桥梁重量。板式橡胶支座由多层天然橡胶与至少两层以上相同厚度的薄钢板镶嵌、粘合、硫化而成一种桥梁支座产品。 A rubber bearing is a bearing that supports the weight of a container or a device and holds it at a certain position. It also bears vibration and seismic loads during operation. Rubber bearings are made of rubber and thin steel plates that are used to support bridge weight. The plate rubber bearing is a kind of bridge bearing product which is inlaid, glued and vulcanized with multilayer natural rubber and at least two layers of thin steel plate with the same thickness. 该种类型的橡胶支座有足够的竖向刚度以承受垂直荷载,且能将上部构造的压力可靠地传递给墩台;有良好的弹性以适应梁端的转动;有较大地剪切变形以满足上部构造的水平位移。 类型划分 Rubber bearings of this type have enough vertical stiffness to bear vertical load, and the upper structure of the pressure can be reliably transferred to the pier; have good flexibility to adapt to the rotation of the beam end; a greater shear deformation to meet the horizontal displacement of superstructure. Type division 板式支座按形状划分:矩形橡胶支座、圆形橡胶支座。 Plate bearings are divided into rectangular rubber bearings and circular rubber bearings by shape. 按是否能够提供水平位移划分为:聚四氟乙烯滑板支座和普通橡胶支座。 According to whether can provide horizontal displacement is divided into: PTFE slide bearing and ordinary rubber bearing. 矩形(圆形)板式橡胶支座 (1)性能:本产品由多层橡胶片与薄钢板镶嵌、粘合在一定压力、一定温度和一定时间内硫化压制而成。有足够的竖向刚度以承压垂直荷载,能将梁板上部构造的反力可靠地传递给墩台,有良好的弹性,以适应梁端的转动;又有较大的剪切变形以满足上部梁体构造的水平位移。 (2)特点:本产品在桥梁建筑、水电工程、房屋抗震设施上已广泛应用,与原用的钢支座相比,有构造 简单,安装方便;节约钢材,价格低廉;养护简便,易于更换等优点,且本品建筑高度低,对桥梁设计与降低造价有益;有良好的隔震作用,可减少活载与地震力对建筑物的冲击作用。 Rectangular (round) plate rubber bearing (1) performance: This product is made of multilayer rubber sheet and thin steel plate inlaid, adhesive, in a certain pressure, a certain temperature and curing within a certain period of time. There are enough vertical stiffness to bearing vertical load, the upper structure of the beam plate can be reliably transferred to the pier force, good flexibility, in order to adapt to the rotation of the beam end; and to meet the horizontal displacement of upper beam structure of large shear deformation. (2) features: This product has been widely used in bridge construction, hydropower projects, housing seismic facilities, compared with the original steel bearing, has simple structure, convenient installation; steel saving, low price; easy maintenance, easy replacement and other advantages, and the low building height, and reduce the cost of bridge design have good beneficial; isolation, live load and seismic force can reduce the impact on the building effect. 聚四氟乙烯滑板式橡胶支座简称四氟滑板式桥梁支座,本产品是于普通板式橡胶支座上粘接一层厚2-3mm的聚四氟乙烯板成。除具有普通板式橡胶支座的竖向刚度与弹性变形,能承受垂直荷载及适应梁端转动外,因四氟乙烯与梁底不锈钢板间的低摩擦系数(μ≤0.03)可使桥梁上部构造的水平位移不受限制,跨度>30米的大跨度桥梁、简支梁连续板桥和多跨连续梁桥可作活动支座使用;连续梁**推、T型梁横移和大型设备滑移可作滑块使用。 The PTFE sliding plate rubber bearing is called PTFE slide bridge bearing. This product is made of a thick 2-3mm PTFE plate bonded on the ordinary plate rubber bearing. In addition to the vertical with normal rubber bearing stiffness and elastic deformation under vertical load and can adapt to the rotation of the outer end of the beam, because of low coefficient of friction between the steel plate and beam bottom tetrafluoroethylene (U = 0.03) the horizontal displacement of the upper structure of the bridge is not restricted, span >30 meters long span bridge, continuous beam bridge and multi span continuous beam bridge can be used as a movable support; continuous beam pushing and shifting of T beam and large equipment can use the slider slip.
