Prefabricated elastomer expansion joint and forming and mounting method
The invention discloses a prefabricated elastomer expansion joint and a forming and installing method.The prefabricated elastomer expansion joint comprises an elastomer arranged between two beam end concrete end faces, the upper surface of the elastomer is a plane, the lower surface of the elastomer is a cambered surface, and the two beam end concrete end faces are coated with primer layers; an adhesive layer is coated between the bottom coating layer and the elastic body, a surface coating layer is arranged on the upper surface of the elastic body, clamping groove protection plates are arranged on the left side and the right side of the lower surface of the elastic body respectively, a plurality of telescopic fastening devices are arranged between the clamping groove protection plates, and width deformation of the elastic body is achieved by adjusting the telescopic fastening devices. The mode that the elastomer expansion joint is prefabricated firstly and then installed is adopted, the clamping groove protection plates and the expansion fastening devices are matched to achieve width deformation of the elastomer expansion joint so as to achieve the purpose of convenient installation, bonding of the elastomer expansion joint and beam body concrete is achieved through the bonding agent, the construction method is convenient and fast, large equipment is not needed, and the construction cost is reduced. Installation under the bridge floor can be achieved, the construction time is not limited by the window period, the construction efficiency is high, and the device is particularly suitable for maintenance work of operating railway elastomer expansion joints.
本发明公开了一种预制式弹性体伸缩缝及成型和安装方法，预制式弹性体伸缩缝包括设置在两个梁端混凝土端面之间的弹性体，弹性体上表面为平面，下表面为弧面，两个梁端混凝土端面涂有底涂料层，底涂料层与弹性体之间涂有粘接剂层，弹性体上表面设有面涂料层，弹性体下表面左右两侧各设有卡槽护板，卡槽护板之间设有多个伸缩紧固装置，调整伸缩紧固装置实现弹性体的宽窄形变。本发明采用弹性体伸缩缝先预制后安装的方式，通过卡槽护板与伸缩紧固装置配合实现弹性体伸缩缝的宽窄形变来达到方便安装的目的，并通过粘接剂实现弹性体伸缩缝与梁体混凝土的粘接，施工方法便捷，无需大型设备，可实现在桥面下安装，施工时间不受窗口期限制，施工效率高，特别适合运营铁路弹性体伸缩缝的维修工作。
