GQF40型桥梁伸缩缝装置

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 joint: refers to meet the requirements of bridge deck deformation, usually in the two beam ends, between Liang Duan and abutment or bridge hinge position to set expansion joints. 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 setting of expansion joints, the railing and deck pavement 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 function of bridge expansion joint is to adjust the displacement and connection between the superstructure caused by the vehicle load and the bridge building material. Once the telescopic device of the skew bridge is destroyed, it will seriously affect the speed, comfort and safety of the vehicle, and even cause safety 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.

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 GQF-MZL model number mode bridge expansion joint device is a bridge expansion joint device designed by the hot rolled integral shaped 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.

GQF40型桥梁伸缩缝装置

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。

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 for the replacement of the old telescopic device, and it can also be used for the new bridge.

GQF-MZL型桥梁伸缩装置特点:

GQF-MZL type bridge expansion device features:

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 the MZL expansion device is characterized by a series of telescopic devices consisting of a side beam, a middle beam, a beam, a displacement control system, a sealed rubber belt and so on. 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 inclined supporting telescopic device requires high accuracy in processing and assembly. Otherwise, the four link structure is prone to self locking phenomenon, which affects the expansion and freedom and is not easy to ensure uniform displacement. The structure of the structure is both rotating and sliding. Therefore, the flexural, slope, oblique and wide bridges have strong adaptability, which can meet the requirements of the use of various bridge structures.
