橡胶支座是由多层薄钢板与多层橡胶片硫化粘合而成一种普通橡胶支座产品,这种产品具有足够的竖向刚度,能够将支座上部构造的反力可靠的传递给墩台,支座具有良好的弹性,以应对桥梁的梁端的转动；又有较大的剪切变形能力，以满足上部构造的水平位移。

Rubber bearing is composed of multilayer thin plate and multilayer sheet rubber vulcanization adhesion and a common rubber bearing products, this product has enough vertical stiffness, can force reliable transfer to the pier upper bearing structure, bearing has good flexibility, to rotate the coping bridge of Liang Duan; and a larger shear the deformation ability, to meet the horizontal displacement of superstructure.

具有构造简单、安装方便、节省钢材、价格低廉、养护简便、易于更换等特点。在板式支座表面粘复一层1.5mm-3mm厚的聚四氟乙烯板,就能制作成聚四氟乙烯滑板式橡胶支座它除了竖向钢度与弹性变形,能承受垂直荷载及适应梁端转动外,因聚四氟乙烯板的低摩擦系数,可使梁端在四氟板表面自由滑动,水平位移不受限制,特别适宜中、小荷载,大位移量的桥梁使用。

It has the characteristics of simple structure, convenient installation, steel saving, low price, easy maintenance and easy to replace. After the Teflon plate 1.5mm-3mm thick layer on the plate bearing surface, can be made of PTFE sliding plate rubber support in addition to its vertical stiffness and elastic deformation under vertical load and can adapt to the rotation of the outer end of the beam, due to the low friction coefficient of PTFE plate, the Liang Duan in the PTFE surface free sliding level the displacement is not restricted, especially suitable for medium and small load, large displacement bridge use.

建筑伸缩缝即伸缩缝，是指为防止建筑物构件由于气候温度变化（热胀、冷缩），使结构产生裂缝或破坏而沿建筑物或者构筑物施工缝方向的适当部位设置的一条构造缝。伸缩缝是将基础以上的建筑构件如墙体、楼板、屋顶（木屋顶除外）等分成两个独立部分，使建筑物或构筑物沿长方向可做水平伸缩。

Expansion joints, namely expansion joints, refer to a structural joint to prevent structural components from cracking or damaging due to climatic and temperature changes, such as thermal expansion and cold shrinkage, along the proper direction of construction joints of buildings or structures. Expansion joints are pided into two independent parts, such as walls, floors, roofs (except wooden roofs), so that buildings or structures can be horizontally telescoped along long directions.
防止房屋因气候变化而产生裂缝。其做法为：沿建筑物长度方向每隔一定距离预留缝隙，将建筑物从屋顶、墙体、楼层等地面以上构件全部断开，建筑物基础因其埋在地下受温度变化影响小，不必断开。伸缩缝的宽度一般为20厘米到30厘米，缝内填保温材料，两条伸缩缝的间距在建筑结构规范中有明确规定。

Prevent cracks in the house from climate change. The method is to reserve gaps in every distance from the length of buildings, and to disconnect buildings from above ground components, such as roofs, walls, floors, etc., because the foundation of buildings is less affected by temperature changes due to their underground burying, so they do not need to be disconnected. The width of the expansion joint is usually 20 cm to 30 cm. The insulation materials are filled in the seams, and the distance between the two expansion joints is clearly defined in the construction code.
