GQF-C型桥梁伸缩缝产品特点: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.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.由于一些伸缩缝安装不适就会产生跳车现象,不但在国内的公路桥梁上存在,在国外也尚未解决,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一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。

GQF-MZL型桥梁伸缩缝的特点

Characteristics of GQF-MZL type bridge expansion joint

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。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 of MZL type telescopic device is characterized by the series of expansion devices composed 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. 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.
