Box girder wet joint formwork mounting and dismounting device and construction method
The invention provides a box girder wet joint formwork mounting and dismounting device and a construction method, and the device comprises a hoisting part which is arranged on a wet joint formwork and is used for lifting and lowering the wet joint formwork to adjust the height of the wet joint formwork; the fixing piece is arranged on the precast beam plate and used for fixing the wet joint formwork; the dismounting part comprises a pulling part and traction parts, the traction parts are temporarily fixed to the front end and the rear end of the same-span precast beam plate correspondingly, the traction parts are arranged on the periphery of the precast beam plate in an annular structure in a surrounding mode, and the two ends of the pulling part are fixedly connected with the traction parts correspondingly; the traction component is used for enabling the pulling component to move towards the formwork to be disassembled along the bottom of the precast beam plate to make contact with the hoisting piece, the wet joint formwork is driven to move towards one side of the bridge floor, and the formwork is dragged to the bridge floor. According to the method, an operator is allowed to complete the dismantling work of the wet joint formwork on the bridge floor, the limitation of factors such as the height of a pier column and the terrain under the bridge on construction is avoided, the construction efficiency is improved, and the safety risk in the construction process is reduced.
本发明提供的一种箱梁湿接缝模板安拆装置及施工方法，包括吊装件，设置在湿接缝模板上用于提升、下放调节湿接缝模板高度；固定件，设置在预制梁板上用于对湿接缝模板进行固定；以及拆卸件，包括拉结部件以及牵引部件，牵引部件分别临时固定在同跨预制梁板的前后两端，且牵引部件成环状结构围设在预制梁板外围，拉结部件的两端分别与牵引部件固定连接；牵引部件用于使拉结部件沿预制梁板底朝待拆模板处移动和吊装件接触，带动湿接缝模板朝桥面一侧移动，将模板拖拽至桥面。本发明方法相允许作业人员在桥面上就能够完成湿接缝模板的拆除工作，不仅避免了墩柱高度、桥下地形等因素对施工的限制，提高了施工效率，而且降低了施工过程中的安全风险。
