一种大高差、大跨度劲性骨架外包混凝土模板施工方法及施工设备
摘要：
本发明公开了一种大高差、大跨度劲性骨架外包混凝土模板施工方法及施工设备，属于混凝土模板施工技术领域。该施工设备由底操作平台、顶操作平台、缆索吊钩组成。底操作平台由贝雷片、底平台、顶平台、扁担梁组成，贝雷片的数量为三组。顶操作平台由主承重梁、操作平台、卷扬机、电动走行葫芦、配电柜、吊耳、底模板、下侧腹板模板、上侧腹板模板、吊杆、对穿拉杆、U型螺栓、护栏、垫座组成；本发明实现了高空、强风环境下拱桥拱圈外包混凝土模板的快速、高精度安装，大大降低了作业安全风险，特别适用于大跨度、大高差条件下拱桥劲性骨架外包混凝土大块模板整体吊装、倒运及拆除作业。
摘要（英）：

The invention discloses a large-height-difference long-span stiff-skeleton cladding concrete formwork construction method and apparatus, and belongs to the technical field of concrete formwork construction. The apparatus comprises a bottom operation platform, a top operation platform and a cable hanger. The bottom operation platform is composed of three sets of beret pieces, a bottom platform, a top platform, and a carrying pole beam. The top operation platform is composed of a main bearing beam, an operation platform, winches, electric travel blocks, power distribution cabinets, lugs, a bottom form, lower web forms, upper web forms, a lifting rod, tie rods, U-shaped bolts, barriers, and pads. The large-height-difference long-span stiff-skeleton cladding concrete formwork construction method and apparatus provide high-speed high-precision mounting of aerial arch bridge arch ring cladding concrete formworks under strong wind, operation safety risk is greatly reduced, and the method and apparatus are suitable particularly for the overall lifting, transferring and removing of long-span large-height-difference arch bridge stiff-skeleton cladding concrete bulky formworks.
