High-altitude ultra-large heavy-load special-shaped overhanging cornice beam plate formwork supporting construction method
The invention discloses a high-altitude ultra-large heavy-load special-shaped overhanging cornice beam plate formwork supporting construction method. Overhanging I-shaped steel, a profile steel inclined strut, an all-round frame, a protection frame, a steel wire rope hanging ring and a vertical diagonal bracing are provided. The construction process flow is as follows: S1, when concrete is poured on a lower floor, 400mm * 400mm * 10mm steel plates are pre-buried, and the pre-buried steel plates are subjected to perforating and plug welding with two to six steel bars which are 100-300mm in length. According to the method, an I-shaped steel coupling beam is installed in the projection range of a vertical rod in the vertical direction on the overhanging I-shaped steel beam, so that the beam bottom, the plate bottom vertical rod, the horizontal rod and the overhanging I-shaped steel beam are stressed uniformly, and the concrete forming quality is good; an overhanging profile steel operation platform which is pulled from the top and supported at the bottom is adopted, so that the stress is clear, the force transmission path is clear, safe and reliable, enough rigidity is achieved, and the structure is not complex; and a turn buckle type steel wire rope is adopted to replace a traditional buckle type steel wire rope for unloading, so that the tightness of the steel wire rope is convenient to adjust, and then the effects of fixing, unloading and reducing the bending moment of the end part of the overhanging I-shaped steel beam can be achieved.
本发明公开了高空超大重载异形悬挑飞檐梁板支模施工方法，包括悬挑工字钢、型钢斜撑、满堂架、防护架、钢丝绳吊环和竖向剪刀撑，施工工艺流程如下：S1：在下部楼层浇筑混凝土时预埋400mm×400mm×10mm的钢板，预埋钢板与2‑6根长度为100‑300mm。本发明通过在悬挑工字钢梁上面垂直方向立杆投影范围安装工字钢联梁，使得梁底、板底立杆、水平杆和悬挑工字钢梁受力均匀，混凝土成型质量较好，通过采用上拉下撑的悬挑型钢操作平台，受力明确、传力途径清晰且安全可靠，具有足够的刚度且构造不复杂，通过采用花篮螺栓式钢丝绳，代替传统的卡扣式钢丝绳卸荷，便于调整钢丝绳的松紧，进而可起到固定、卸荷和减轻悬挑工字钢梁端部的弯矩作用。
