The utility model belongs to the field of wet joint construction for highway bridge, and discloses a foldable inner hanging basket for wet joint construction of highway bridge. Four vertical bars are stuck to the operating platform; the four vertical rods are welded with a casing; the cross bar between the adjacent vertical rods is inserted in the casing; and the climbing ladder is also stuck on the operating platform; the exercise is also connected with a climbing ladder. A plurality of platform cross bars are welded between two main girders of the platform, and a protective net is arranged at the periphery of the operation platform and the four vertical poles. The inner hanging basket provided by the utility model is connected by four active connecting rods, and the operation platform is controlled by the distance between the upper edge of the two T beams and horseshoes, and the whole is movable, foldable, up and down ladder, and the builders enter the construction platform through the climbing ladder; the construction personnel are lightweight, good integrity and good stability. The flexible effect is remarkable, safe and reliable. It is suitable for the operation platform of wet joint, prestressed negative bending moment tension and grouting between two adjacent beams of precast T beam (or prefabricated box girder).
【技术实现步骤摘要】
一种公路桥梁湿接缝施工用折叠式内挂篮
本技术属于公路桥梁湿接缝施工用设备领域,尤其涉及一种公路桥梁湿接缝施工用折叠式内挂篮。
技术介绍
目前桥梁施工时在完成梁体架设后,需进行湿接缝施工,即在梁缝之间灌注混凝土,把梁体横向连接起来,以使梁体相互固结成为一个整体。由于桥梁往往跨越山谷、河流,下部往往不便于架设支架,故湿接缝施工属于高空作业,其通常施工方法是:以木模作为湿接缝施工的底模,采用铁丝将木模吊挂于梁体底部平面上,湿接缝施工完后剪断铁丝,再将底模逐一敲落。亦有预留吊挂孔道以便于拆模的方法。而且随着现代桥梁施工技术的发展,桥梁高度逐渐增高,拼装式桥梁湿接缝施工的技术优越性也越来越重要,怎样使湿接缝的施工操作更安全便捷,且效率更高,成为桥梁施工的一项重要内容。现有的施工技术:一、需要人到梁底下进行施工,制作施工平台,从梁上通过爬梯到梁底下的工作平台上进行施工。二、用升降机械,形成操作平台,人员在操作平台上进行操作,这两种施工方法对模板安装或拆卸的运送都比较繁琐,对机械的要求较高,施工效率低,成本较高,且施工人员的安全度较低,桥下场地也受到限制,影响了桥下交通。现有技术三:一种桥梁湿接缝作业车,包括有车架、车轮、上抬梁、和底模,底模安装在湿接缝、下表面,车架和车轮组成在可沿湿接缝上表面移动的小车,小车与底模将湿接缝夹持在中间,车架上还设置有上抬梁,上抬梁处于湿接缝中心位置,通过穿过湿接缝的螺杆与底模连接。所述的上抬梁为槽钢结构,开口朝下固定在车架顶部中间,上抬梁水平沿湿接缝方向设置。现有技术三的缺点:使用和操作麻烦,对于宽幅大断面的桥梁施工存在不足。综上所述, ...
