建筑伸縮縫即伸縮縫，是指為防止建筑物構(gòu)件由于氣候溫度變化（熱脹、冷縮），使結(jié)構(gòu)產(chǎn)生裂縫或破壞而沿建筑物或者構(gòu)筑物施工縫方向的適當(dāng)部位設(shè)置的一條構(gòu)造縫。伸縮縫是將基礎(chǔ)以上的建筑構(gòu)件如墻體、樓板、屋頂（木屋頂除外）等分成兩個(gè)獨(dú)立部分，使建筑物或構(gòu)筑物沿長方向可做水平伸縮。
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.
防止房屋因氣候變化而產(chǎn)生裂縫。其做法為：沿建筑物長度方向每隔一定距離預(yù)留縫隙，將建筑物從屋頂、墻體、樓層等地面以上構(gòu)件全部斷開，建筑物基礎(chǔ)因其埋在地下受溫度變化影響小，不必?cái)嚅_。伸縮縫的寬度一般為20厘米到30厘米，縫內(nèi)填保溫材料，兩條伸縮縫的間距在建筑結(jié)構(gòu)規(guī)范中有明確規(guī)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.
若建筑物平面尺寸過長，因熱脹冷縮的緣故，可能導(dǎo)致在結(jié)構(gòu)中產(chǎn)生過大的溫度應(yīng)力，需在結(jié)構(gòu)一定長度位置設(shè)縫將建筑分成幾部分，該縫即為溫度縫。對不同的結(jié)構(gòu)體系，伸縮縫間的距離不同，中國現(xiàn)行規(guī)范《混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范》GB50010-2010中8.1條對此有專門規(guī)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.
為滿足橋面變形的要求，通常在兩梁端之間、梁端與橋臺(tái)之間或橋。
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.

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.
橡膠墊塊的布置
The arrangement of rubber padding blocks
橡膠墊塊的布置主要和橋梁的結(jié)構(gòu)形式有關(guān)。通常在布置支座時(shí)需要考慮以下的基本原則:
The layout of the rubber pad is mainly related to the structural form of the bridge. The following basic principles should usually be taken into consideration in the arrangement of support:
(1)上部結(jié)構(gòu)是空間結(jié)構(gòu)時(shí)，橡膠墊塊應(yīng)能同時(shí)適應(yīng)橋梁順橋向(X方向)和橫橋向(Y方向)的變形;
(1) when the superstructure is a spatial structure, the rubber pad should be able to adapt to the deformation of the bridge direction (X direction) and the transverse bridge (Y direction).
(2)橡膠墊塊必須能可靠的傳遞垂直和水平反力;
