平面型桥梁伸缩缝

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。

The bridge expansion joints refer to the expansion joints to meet the requirements of bridge deck deformation， usually between the two beam ends， between 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 setting of expansion joints， the railing and deck pavement should be disconnected.

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、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.

Joints according to performance and installation methods can be divided into GQF-C type， GQF-Z type， GQF-L type， GQF-F type， GQF-MZL type model of bridge expansion joint device， is the overall design of special-shaped steel bridge expansion joint apparatus. The hot forming of GQF-C type， GQF-Z type， GQF-L type， GQF-F type jointless bridge the 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 of 80mm-1200mm.

公路桥梁伸缩缝装置分为：模数式桥梁伸缩装置和KS伸缩装置以及TST弹塑体伸缩缝装置

The expansion joints of road and bridge are divided into the modulus bridge expansion device and the KS expansion device and the TST elastic plastic expansion joint

一、模数式桥梁伸缩缝装置

模数式桥梁伸缩缝装置分为：GQF-C型桥梁伸缩缝装置、GQF-MZL型桥梁伸缩缝装置

The expansion joint device of the model bridge type bridge is divided into GQF-C type bridge expansion joint and GQF-MZL bridge expansion joint

1、GQF-C型桥梁伸缩缝装置特点：GQF-C型桥梁伸缩缝装置采用整体热轧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。

1， GQF-C type bridge expansion joint device features GQF-C type bridge expansion joint device adopts the whole hot r 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， simple structure， convenient installation， with comfort obviously， reliability and durability. It is convenient for the replacement of the old telescopic device， and it can also be used for the new bridge.

选用原则： 桥面铺装层厚度80mm 伸缩量80mm

The selection principle pavement thickness of 80mm the expansion amount is less than or equal to 80mm

2、GQF-MZL型桥梁伸缩缝装置特点：MZL型伸缩缝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。该伸缩缝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缝装置非常有利，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。该结构还克服了斜向支承式伸缩缝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。

2， GQF-MZL type bridge expansion joint device features MZL expansion joint device structure outstanding characteristics are by side beam， middle beam， crossbeam， displacement control system， seal rubber belt and other components of a series of expansion device. Separate device load-bearing structure and displacement control system of the telescopic joint， 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， the telescopic the displacement of joint device 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 that the inclined support expansion joint 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.
