PTFE sliding plate rubber support in addition to its vertical stiffness and elastic deformation under vertical load and can adapt to Liang Duan rotation, due to the low friction coefficient of PTFE plate, the beam end in PTFE sliding surface, the horizontal 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 divided 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.

若建筑物平面尺寸过长，因热胀冷缩的缘故，可能导致在结构中产生过大的温度应力，需在结构一定长度位置设缝将建筑分成几部分，该缝即为温度缝。对不同的结构体系，伸缩缝间的距离不同，中国现行规范《混凝土结构设计规范》GB50010-2010中8.1条对此有专门规定。

If the plane size of a building is too long, it may cause excessive temperature stress in the structure due to thermal expansion and cold contraction. It is necessary to sew the building into several parts at a certain length, and the joints are temperature joints. For different structural systems, the distance between expansion joints is different. The 8.1 rule in the code for design of concrete structures in China is GB50010-2010.
