建筑物伸缩缝GQF-60型

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.

Bridge expansion joints GQF-C, GQF-Z, GQF-E, GQF-F and GQF-MZL are all welded expansion joint products designed by hot rolled integral shaped steel. The GQF-C type, GQF-Z type, GQF-L type, GQF-F type bridge expansion device is suitable for the expansion of the 80mm below the bridge, GQF-MZL bridge expansion device is composed of modular bridge expansion edge beam, beam, beam and linkage mechanism joint device, suitable for large and medium span bridge expansion 80mm-1200mm.

为满足桥面变形的要求，通常在两梁端之间、梁端与桥台之间或桥。

In order to meet the requirements of the deformation of the bridge, it is usually between the two beam ends, between the Liang Duan and the abutment or the bridge.

橡胶垫块是由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。

The rubber pad is composed of multilayer rubber vulcanization bonding 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, rotating beam end in response to the bridge; and a larger shear deformation capacity in order to meet, the horizontal displacement of superstructure.
