Construction method for cast-in-place beam of fabricated overall frame structure without opening and formwork support
The invention provides a construction method for a cast-in-place beam of a fabricated overall frame structure without opening and a formwork support. The construction method comprises the following steps that 1) steel plates are pre-buried at the connecting positions of the side faces of prefabricated beams and the cast-in-place beam; 2) vertical steel plates are welded to the pre-buried steel plates; 3) the two ends of cast-in-place beam supporting channel steel are welded to the bottoms of the vertical steel plates on the pre-buried steel plates on the two sides correspondingly; 4) square tube back edges are laid on the channel steel, and formworks are laid on the back edges to serve as bottom formworks; 5) prefabricated beam reinforcement cages are placed on the bottom formworks, and the two ends of bottom bars and waist bars of the reinforcement cages located at the pre-vertical steel plates are welded to the vertical steel plates correspondingly; 6) after upper steel bars of the cast-in-place beam, plate bars and prefabricated beam laminated layer steel bars are bound synchronously, side formworks are erected on the two sides of the cast-in-place beam and fixed; 7) the cast-in-place beam, the prefabricated beams and the plates are poured synchronously; and 8) the side formworks, the bottom formworks and the supporting channel steel are dismounted. According to the construction method, operation is easy, the construction efficiency is improved, and the mounting operation requirements of a construction site can be effectively met.
一种装配式整体框架结构现浇梁免开孔及免支模架施工方法，其步骤包括如下：1)在预制梁侧面与现浇梁连接处预埋钢板；2)在预埋钢板上焊接竖向钢板；3)现浇梁支撑槽钢的两端分别焊接在两侧的预埋钢板上的竖向钢板底部；4)在槽钢上面铺设方管背楞，在背楞上铺设模板作为底模；5)在底模上放置预制梁钢筋笼，位于预竖向钢板处的钢筋笼底筋与腰筋两端分别焊接在竖向钢板上；6)现浇梁上部钢筋与板筋、预制梁叠合层钢筋同步绑扎后，在现浇梁两侧支设侧模并固定；7)现浇梁、预制梁及板同步浇筑；8)拆侧模、底模和支撑槽钢。本发明操作简单，提高施工效率，能有效满足施工现场安装作业需求。
