Bottom die floor support plate construction technology suitable for construction of cast-in-place bridge deck slab of reinforced concrete superposed beam
The invention discloses a bottom die floor support plate construction process suitable for construction of a cast-in-place bridge deck slab of a reinforced concrete superposed beam, belongs to the field of cast-in-place concrete member template construction, and can solve the problems that a bottom die of the cast-in-place bridge deck slab of the reinforced concrete superposed beam is difficult to install, a large amount of building materials are wasted, the cost is increased and the construction period is slow. Pay-off is conducted at the reinforcing position of a steel beam top plate according to the size of the floor bearing plates, and the arranged floor bearing plates are installed, connected, straightened, flattened, connected and fixed. Connection between the floor bearing plates is reinforced through fillet welding, cantilever arms on the two sides of the edge of the steel-concrete composite beam are 70 cm respectively, and the thickness of concrete is 20 cm. Construction is conducted on the cantilever portions of the boundary beams through a formwork hanging method, and profile steel cantilever beams are arranged on the tops of the steel beams to hoist the bottom formwork of the steel bar truss floor support plate. And after the floor bearing plates are paved, steel bars are bound, and bridge deck slabs are poured. The steel bar truss floor support plate meets various loads of structures, construction and the like, the construction procedures of formwork erecting, formwork disassembling, supporting system assembling and disassembling and the like can be omitted, and the construction operation efficiency is improved.
一种适应于钢混叠合梁现浇桥面板施工的底模楼承板施工工艺，属于现浇混凝土构件模板施工领域，可解决钢混叠合梁现浇桥面板底模安装困难，建筑材料大量浪费，增加成本、施工周期慢的问题，本发明依据楼承板尺寸在钢梁顶板进行加固位置放线，进行安装、连接，调直、压平、连接固定已排列好的楼承板。楼承板之间的连接加贴角焊进行加固，钢混叠合梁梁边两侧挑臂各70cm，混凝土厚20cm。对于边梁挑臂部位采用吊模法施工，在钢梁顶设置型钢悬挑梁将钢筋桁架楼承板底模吊起。楼承板铺装完成后，绑扎钢筋，浇筑桥面板。钢筋桁架楼承板满足结构、施工等各种荷载，可免去支模、拆模、安拆支撑体系等施工工序，提高施工作业效率。
