Bridge expansion joints GQF-C type, GQF-Z type, GQF-E type, GQF-F type and GQF-MZL type, all are made of hot rolled whole shaped special-shaped steel designed bridge expansion joint products. 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.
To meet the requirements of bridge deformation, it is usually between two beam ends, between Liang Duan and abutment or bridge.
Structural requirement
(1) it can be freely extended in two directions parallel and perpendicular to the axis of the bridge
(2) firm and reliable;
(3) vehicles passing by Ying Pingshun, without jumping and noise;
(4) waterproof and prevent sundries from permeating and blocking
(5) installation, inspection, maintenance and elimination of dirt are simple and convenient

主要作用
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毫米到30毫米，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。
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。
类型
桥梁伸缩缝GQF-C型、GQF-Z型、GQF-E型、GQF-F型、GQF-MZL型,全都是采用热轧整体成型的异型钢材设计的桥梁伸缩缝产品。其中GQF-C型、GQF-Z型、GQF-L型、GQF-F型桥梁伸缩装置适用于伸缩量80mm以下的的桥梁, GQF-MZL型桥梁伸缩装置型是由边梁、中梁、横梁和连动机构组成的模数式桥梁伸缩缝装置,适用于伸缩量80mm-1200mm的大中跨度桥梁。
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。
构造要求
（1）在平行、垂直于桥梁轴线的两个方向均能自由伸缩
（2）牢固可靠
（3）车辆驶过应平顺、无突跳与噪声
（4）防水及防止杂物渗入阻塞
（5）安装、检查、养护、消除污物都要简易方便

Main function
Prevent housing from cracks due to climate change. The approach is: the buildings along the length direction at a distance from the gap, the building roof, walls, floors above ground members are disconnected, building foundation because of the change of temperature in the underground buried small, need not disconnect. The width of the expansion joint is usually 20 millimeters to 30 millimeters, and the insulation material in the seam is filled. The space between the two expansion joints is clearly defined in the building construction specification.
If the building plane size is too long, because of risk factors, may lead to excessive temperature stress in the structure, the structure of a certain length position of joints of the building is divided into several parts, the seam is temperature cracks. For different structural systems, the gap between the expansion joints is different, Chinas current code "concrete structural design code" GB50010-2010, 8.1 articles have special provisions on this.
