GQF40型桥梁伸缩缝规格
 桥梁伸缩缝:指的是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梁的铰接位置上设置伸缩缝。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。
Bridge expansion joints: to meet the requirements of bridge deck deformation, the expansion joint is usually installed between the two beam ends, between the Liang Duan and abutment or the hinge position of the bridge. Requirements of expansion joints 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, eliminate dirt to be simple. At the expansion joint, the railing and the bridge deck should be disconnected.
桥梁伸缩缝的作用:在于调节由车辆荷载和桥梁建筑材料所引起的上部结构之间的位移和联结。斜交桥的伸缩装置一旦被破坏,将严重影响行车的速度、舒适性与安全,甚至造成行车安全事故。
The role of bridge expansion joints is to adjust the displacement and connection between the superstructure caused by the vehicle load and the bridge building materials. Once the telescopic device of the skew bridge is damaged, it will seriously affect the speed, comfort and safety of the train, and even cause traffic accidents.
伸缩缝按照性能及安装方法可以分为:GQF-C型、GQF-Z型、GQF-L型、GQF-F型。
According to the performance and installation method, the expansion joint can be divided into GQF-C, GQF-Z, GQF-L and GQF-F types.
其中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。GQF-C型、GQF-Z型、GQF-L型、GQF-F型伸缩缝装置适用于伸缩量80mm以下的的桥梁接缝,GQF-MZL型伸缩缝装置是由边梁、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。
The bridge expansion joint device of GQF-MZL number model is a bridge expansion joint device which is made of hot-rolled profiled steel. GQF-C type, GQF-Z type, GQF-L type, GQF-F type jointless bridge joint device is suitable for the expansion of the following 80mm, GQF-MZL type expansion joint 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.
GQF-C型桥梁伸缩装置特点:
Characteristics of GQF-C type bridge expansion device:
GQF-C型桥梁伸缩装置采用整体热轧16Mn异型钢,克服了挤压异型钢直线度和集合尺寸不均匀的特点, 建筑高度低,国产热轧整体成型异型钢材高度仅50mm,结构简单,安装方便,具有明显的可靠性、舒适性和耐久性。既方便旧伸缩装置更换,又可供新桥时选用。

GQF40型桥梁伸缩缝规格
Type GQF-C bridge expansion device adopts whole hot rolled 16Mn shaped steel, overcome the extrusion special-shaped steel straightness and set size uneven, low building height, homemade hot rolled profiled steel forming the overall height of only 50mm, has the advantages of simple structure, convenient installation, with comfort and durability, reliability obvious. It is convenient to replace the old telescopic device and can be used for the new bridge.
GQF-MZL型桥梁伸缩装置特点:
Characteristics of GQF-MZL type bridge expansion device:
MZL型伸缩装置结构突出的特点是: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装置。该伸缩装置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装置非常有利,减少了横梁数量,使位移控制箱体积减小到*小范围,节约了钢材。
The structure of MZL telescopic device is characterized by: a series of telescopic devices consisting of side beam, middle beam, crossbeam, displacement control system, sealing rubber belt and other components. Apart from the expansion device of 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 in a displacement control box are supported on the same vertical beam of the traditional method, so on large displacement expansion device is very favorable, reducing the number of beams, the displacement of the control box volume is reduced to the minimum, saving steel.
该结构还克服了斜向支承式伸缩装置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。
The structure also overcomes the harsh conditions that the oblique supporting telescopic device requires a high precision of processing and assembly, otherwise, the self-locking phenomenon of the four link structure is easy to occur, which affects the telescopic freedom and the disadvantage that the displacement is not easy to be guaranteed. All the joints of the structure are both rotational and sliding structures. Therefore, the bridge has strong adaptability to curved, sloping, inclined and wide bridges, which can meet the requirements of various bridge structures.
