Large-cantilever floor steel beam group and efficient installation and construction method
The invention provides a large-cantilever floor steel beam group and an efficient installation and construction method. The large-cantilever floor steel beam group comprises a connecting anchor plate and an in-plate anchor plate which are arranged in a concrete frame beam and an upper floor slab correspondingly and connected with a vertical supporting plate; an adjustable bottom support is arranged at the bottom of the bracket unit, and an integral tie bar is arranged in the bracket unit; a connecting hoop groove is formed in the connecting portion of the first section and the stiff connecting plate, and the second pull rod and the first pull rod apply larger fastening force to the prestress tenon plate. Inclined upward pulling force is applied to the supporting cross beam through the inclined pull rod; hoisting connecting cables are arranged on the upper surfaces of the two hoisting hoops of the supporting cross beam, beam bottom supporting plates are arranged on the lower surfaces of the two hoisting hoops, and upward jacking pressure is applied to the supporting cross beam through a hoisting stress control body; a connecting clamping groove and a position adjusting pull rod are arranged on the first section, so that section connecting plates can be pushed and positioned; the paint spraying tackle capable of longitudinally moving along the supporting cross beam is adopted for paint spraying operation. The integrity of the section steel beam can be effectively improved, and installation stress and flexural deformation are reduced.
本发明提供一种大悬挑楼层钢梁群及高效安装施工方法，包括在混凝土框梁和上层楼板内分别设置了与竖向撑板连接的连接锚板和板内锚板；在支架单元的底部设置了可调底撑，内部设置了整体拉筋；在第一节段与劲性连板连接部位设置了连接箍槽，并使第二拉杆和第一拉杆对预应力隼板施加更大的紧固力；通过斜向拉杆对支撑横梁施加斜向上拉力；在支撑横梁的两吊装抱箍的上表面设置吊装连索，下表面设置了梁底撑板，并通过吊装应力控制体对支撑横梁施加向上的顶压力；在第一节段上设置了连接卡槽和调位拉杆，可进行节段连板顶推定位；采用可沿支撑横梁纵向移动喷漆滑车进行喷漆作业。本发明可有效提升型钢梁的整体性，减小安装应力和挠曲变形。
