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 joint refers to the expansion joint which is usually arranged between the two beam ends, between the Liang Duan and the abutment or the hinge position of the bridge to meet the requirements of the bridge deck deformation. 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*般有模数式桥梁伸缩装置和KS伸缩装置以及TST弹塑体伸缩装置
At present, the bridge expansion joints of Changtai Hengshui Engineering Rubber Co., Ltd. generally have modulus type bridge expansion device and KS expansion device, and TST elastic plastic telescopic device
桥梁伸缩缝常见的几种型号有c型,D型,E型,F型,异型伸缩缝的型号有很多,按照伸缩缝的性能及伸缩缝安装方法,是采用热轧整体成型的异型钢材设计的桥梁伸缩缝装置可分为;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;
Hengshui bridge expansion joint of several types of common C type, D type, E type, F type, there are many shaped expansion joint model, joint installation method according to performance and expansion joints, special-shaped steel bridge expansion is the overall design of the hot rolling forming joint device can be divided into; GQF-C type, GQF-Z type, GQF-L type, GQF-F type jointless bridge joint device is suitable for the expansion of 80mm or less;
GQF-C型桥梁伸缩装置中间橡胶密封条其技术要求:采用氯丁橡胶(CR)密封橡胶带的伸缩装置适用与温度为-25℃-+60℃地区.采用天然橡胶(NR)密封橡胶带的[1]装置适用于温度为-40℃-+60℃地区
The technical requirements of the intermediate rubber sealing strip for GQF-C bridge expansion device: the rubber expansion device of chloroprene rubber (CR) is suitable for the region with temperature of -25 degrees -+60 degrees. The [1] device using natural rubber (NR) sealing rubber belt is suitable for the temperature of -40 degrees -+60 degrees centigrade
(2)、GQF-MZL型桥梁伸缩装置特点: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*个位移控制箱内均支承在同*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。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。

GQF-F型桥梁伸缩缝产品特点:建筑高度低,*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.适用于桥面铺装层厚度等于或大于80mm,伸缩量小于等于80mm的各种桥梁,既方便旧桥梁伸缩缝更换,又可供新桥梁修建选用.由于*些伸缩缝安装不适就会产生跳车现象,不但在*内的公路桥梁上存在,在*外也尚未解决,因此,我们为了消除台阶,防止跳车,保持良好的路况,有关部门及施工单位采用了许多行之有效的措施与办法,在动难逃很大程度上减少了桥梁伸缩缝处跳车病害。其中桥梁伸缩缝的安装施工是公路桥梁建设中*项极为重要的施工项目,安装质量的好坏直接影响到行车的平稳性和舒适性、大型桥梁的服务质量及使用年限。
The GQF-F type jointless bridge features: low building height, homemade hot rolled profiled steel forming the overall height of only 50mm, has the advantages of simple structure, convenient installation, obvious reliability, comfort and durability. Suitable for pavement thickness is equal to or greater than 80mm and less than or equal to a variety of bridge expansion of 80mm, both for the convenience of the old bridge joint replacement, and can be used for the new bridge built in use. Due to the installation of discomfort will produce jumping phenomenon not only exists in the expansion joint, the domestic highway bridge, in foreign countries also have not been solved. Therefore, we in order to eliminate the step, prevent bump, keep a good road, the relevant departments and construction units by many effective measures and methods, in can largely reduce the bridge expansion joints bump. The installation and construction of bridge expansion joints is a very important construction project in the construction of highway bridges. The quality of installation directly affects the stability and comfort of driving, the service quality and service life of large bridges.

The natural rubber (NR) sealing rubber belt expansion joint device is suitable for the area with -40 -40 -+60 temperature.
公路桥梁伸缩缝是*种设置于桥梁上部结构活动端、桥面断缝处的伸缩装置。安装伸缩装置的作用是用以保证上部结构在温度变化、混凝土收缩和徐变,以及荷载作用下,在该处的变位能够实现,而不产生额外的附加内力,并能保证行车平顺。通常*内的桥梁伸缩缝都设置在上部结构的活动端和桥台,以及各联(孔)上部结构衔接处。*般公路桥在车行道和人行道上沿桥的横方向通长设置,栏杆在接缝处亦须中断以保证结构的自由变位,避免拉裂;在接缝处的桥面防水层仍应妥善铺设,防止雨水侵蚀承重结构。如采用敞口式的桥梁伸缩缝,还应考虑便于清除污物,并在缝下设置截水和引水装置,使积水排出桥外。*内的中型、大型铁路桥同理也需设伸缩缝,在道碴桥面中,应考虑防止道碴坠落缝中的措施。
