Cantilever stiff concrete beam suspended formwork construction method
The invention discloses an overhanging stiff concrete beam hanging formwork construction method which comprises the steps that S1, overhanging stiff steel beams are sequentially hoisted, and the overhanging stiff steel beams are connected with steel columns in a welded mode; s2, a plate bottom formwork support, a beam bottom operation frame and a beam side outer protection frame are erected; s3, the jacking is screwed to the elevation position of the main edge, and the beam bottom main edge, the secondary keel and the beam bottom die are installed on the basis of the beam bottom operation frame; s4, cantilever stiff steel beam steel bars are installed; s5, the U-shaped screws are sequentially hung on the cantilever stiff steel beam from top to bottom in an inverted mode; s6, the main back ridges are fixed through gaskets and double nuts; s7, a side formwork of the cantilever stiff steel beam is installed and reinforced; s8, pouring the cantilever stiff steel beam by adopting a layered intermittent pouring method; and S9, the side formwork and the beam bottom formwork are sequentially dismantled, and the U-shaped screw exposed out of the beam bottom is cut off. The problems that in cantilever stiff concrete beam construction, a cantilever formwork support is difficult to erect, and stress of a lower floor slab structure cannot pass through possibly are solved.
本发明公开了一种悬挑劲性混凝土梁吊模施工方法，包括S1、依次吊装悬挑劲性钢梁，并将悬挑劲性钢梁与钢柱焊接相连；S2、搭设板底支模架、梁底操作架和梁侧外防护架；S3、将顶托拧至主楞标高位置，基于梁底操作架安装梁底主楞、次龙骨和梁底模；S4、安装悬挑劲性钢梁钢筋；S5、将U型螺杆从上向下依次倒置吊挂在悬挑劲性钢梁上；S6、采用垫片及双螺母对主背楞进行固定；S7、安装悬挑劲性钢梁的侧模板并对该侧模板进行加固；S8、采用分层间歇浇筑法对悬挑劲性钢梁进行浇筑；S9、依次拆除侧模板、梁底模、并割除露出梁底的U形螺杆。本发明克服了悬挑劲性混凝土梁施工中的悬挑支模架搭设困难、下层楼板结构受力可能无法通过等问题。
