MZL模数式伸缩缝
MZL modular expansion joint
GQF-MZL型数模式桥梁伸缩缝装置,是采用热轧整体成型的异型钢材设计的桥梁伸缩缝装置. 桥梁伸缩缝伸缩体完全由橡胶密封带组成的伸缩装置。由单缝钢和橡胶密封带组成的单缝式伸缩装置，适用于延伸缩量不大于60mm的公路桥梁工程伸缩；由边梁和橡胶密封带组成的单缝式伸缩装置，适用于伸缩量不大于80mm的公路桥梁工程。
The GQF-MZL type numerical expansion joint device is a bridge expansion joint device designed by using hot-rolled profiled steel, and the expansion joint of the bridge expansion joint is entirely made up of rubber sealing belt. By the single slit slit telescopic device of steel and rubber sealing belt composed of the highway bridge engineering expansion applied to extend the shrinkage of not more than 60mm; the side beam and the rubber sealing slit telescopic device with the highway bridge engineering applied to the expansion amount of not more than 80mm.
GQF-MZL型桥梁伸缩缝突出的特点是：由边梁、中梁、横梁、位移控制系统、密封橡胶带等构件组成的系列伸缩缝。该伸缩缝的承重结构和位移控制系统分开，二者受力时互不干扰，分工明确，这样既保证受力时安全，又能达到位移均匀，使所有中梁在一个位移控制箱内均支承在同一根垂直横梁上的传统作法，这样对大位移量伸缩缝非常有利，减少了横梁数量，使位移控制箱体积减小到最小范围，节约了钢材。该结构还克服了斜向支承式伸缩缝要求加工和组装精度相当高的苛刻条件，否则四连杆结构极易出现自锁现象，影响伸缩自由和不易保证位移均匀的弊病。该结构各连接处均采用既能转动又能滑动结构。所以，对弯、坡、斜、宽桥梁适应能力强，可满足各种桥梁结构使用要求。
GQF-MZL bridge expansion joints are characterized by: side beam, middle beam, beam, displacement control system, sealing rubber belt and other components of a series of expansion joints. Apart from the joints of the load-bearing structure and displacement control system, the two forces do not interfere with each other, a clear division of labor, so as to ensure the safety of the force, and can achieve the uniform displacement, so that all beams of traditional practices in a displacement control box are supported on the same vertical beam, so the expansion of large displacement of joints is very beneficial to reduce the number of beams, the displacement of the control box volume is reduced to the minimum, saving steel. The structure also overcomes the harsh conditions of the oblique supporting type expansion joint require processing and assembly precision is very high, otherwise the four connecting rod structure prone to self-locking phenomenon, affect the expansion of freedom and is not easy to ensure uniform displacement of ills. The joints of the structure are both rotational and sliding. Therefore, the bending, slope, skew and wide bridge adaptability is strong, and can meet the use requirements of various bridge structures.
桥梁伸缩缝要求伸缩缝在平行、垂直于桥梁轴线的两个方向，均能自由伸缩，牢固可靠，车辆行驶过时应平顺、无突跳与噪声；要能防止雨水和垃圾泥土渗入阻塞；安装、检查、养护、消除污物都要简易方便。 在设置伸缩缝处，栏杆与桥面铺装都要断开。
Requirements of bridge expansion joint expansion joint in two directions parallel and perpendicular to the axis of the bridge, can free expansion, firm and reliable, the vehicle had to be smooth, no sudden jump and noise; to prevent rainwater and waste soil infiltration obstruction; installation, inspection, maintenance, simple and convenient to remove the dirt. In setting expansion joints, railings and bridge pavement should be disconnected.
桥梁伸缩缝的类型及分类
Types and classification of bridge expansion joints
1、镀锌薄钢板伸缩缝。在中小跨径的装配式简支梁桥上，适用于伸缩量80mm-1200mm的大中跨度桥梁。
1 、 galvanized steel sheet expansion joint. In the small span span simply supported beam bridge, it is suitable for large and medium span bridges with 80mm-1200mm expansion capacity.
2、钢伸缩缝:它的构造比较复杂，只有在温差较大的地区或跨径较大的桥梁上才采用。钢伸缩缝也宜于在斜桥上使用。
2, steel expansion joint: its structure is more complex, only in the temperature difference area or span bridge. Is also suitable for the use in bridge steel telescopic joint.
3、橡胶伸缩缝。它是以橡胶带作为跨缝材料。这种伸缩缝的构造简单，使用方便，效果好。在变形量较大的大跨度桥上，可以采用橡胶和钢板组合的伸缩缝
3 、 rubber expansion joint. It is made of rubber belt as a cross stitch material. The expansion joint has the advantages of simple structure, convenient operation and good effect. On the large span bridge with large deformation, the expansion joint of rubber and steel plate can be adopted
