Cast-in-place continuous box girder formwork system and construction method
The invention relates to a cast-in-place continuous box girder formwork system which comprises a pile-supported cast-in-place continuous box girder support system, a cast-in-place continuous box girder outer die and a cast-in-place continuous box girder inner die; the pile-supported cast-in-place continuous box girder support system comprises distributive girders, bailey beams, bearing beams, buckling devices, steel stand columns, horizontal supporting rods, scissor supporting rods, connecting steel plates, flange plates, reinforcing ribs, a soft base layer, a hard base layer, pinch plate rings and cast-in-place piles; the cast-in-place continuous box girder outer die comprises flange plate dies, hinge bolts, back ribs, side dies, a bottom die, a safety net, supporting rods, an adjustablejacking, distribution beams, bailey beams, bearing beams, diagonal bracings and steel stand columns; the cast-in-place continuous box girder internal die comprises a steel panel, side ribs, second bolts, steel bars, supporting rods, adjustable jacking supports, jacking ribs, positioning steel bars and first bolts. The cast-in-place continuous box girder formwork system has the beneficial effects that a pile-supported steel stand column buckling device is adopted, so that a cast-in-situ bored pile steel stand column and an upper transverse bridge direction bearing beam can be quickly connectedand easily detached, and connection is safe and stable.
本发明涉及现浇连续箱梁支模体系，包括桩承式现浇连续箱梁支架体系、现浇连续箱梁外模和现浇连续箱梁内模；所述桩承式现浇连续箱梁支架体系包括分配梁、贝雷梁、承重梁、卡扣装置、钢立柱、水平撑杆、剪刀撑杆、连接钢板、法兰板、加强肋、软基层、硬基层、扣板圈和灌注桩；所述现浇连续箱梁外模包括翼缘板模、铰接螺栓、背肋、侧模、底模、安全网、撑杆、可调顶托、分配梁、贝雷梁、承重梁、剪刀撑和钢立柱；所述现浇连续箱梁内模包括钢面板、侧肋、第二螺栓、条钢、撑杆、可调顶托、顶肋、定位钢筋和第一螺栓。本发明的有益效果是：本发明设置的桩承式钢立柱卡扣装置，使钻孔灌注桩钢立柱与上部横桥向承重梁能够快连易拆，连接安全稳固。
