Description

一种桥梁伸缩缝结构 技术领域
本发明属于道路工程技术领域，具体涉及一种桥梁伸缩缝结构。
背景技术
随着社会的不断发展，我国经济的飞速发展，道路作为国家的命脉也得到了空前发展。在桥梁的连接处以及两端道路的连接处均设置伸缩缝，用于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；安装、检查、养护、消除污物都要简易方便。桥梁伸缩缝一旦被破坏，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。
而目前的桥梁伸缩缝的结构也不够牢固，车辆长时间驶过存在安全隐患；再者，现在伸缩缝的连接均是通过钢板进行简单的连接，而这种构造方式往往为了省事直接将钢板做固定连接，既不可拆卸连接，日常使用时，不能对伸缩缝进行常规检查与维护，存在安全隐患；且由于钢板比较硬，因此，采用钢板连接的伸缩缝存在着行车舒适性较差，行车过程中易发生跳车，所以设计出具有较好的承载力，稳固性好，满足桥梁伸缩变形，耐用的伸缩缝结构具有很实用的意义。
