Nuclear island CV bottom head A-layer steel bar modular prefabricating tool and construction method
The invention discloses a nuclear island CV bottom seal head layer A steel bar modular prefabricating tool and a construction method.The prefabricating tool comprises a steel beam, a steel column, a column base bottom plate and a lifting lug, and the steel beam is of a latticed structure and has the bending radian matched with the spherical surface of a CV bottom seal head; the steel columns are fixedly connected with the lower sides of the steel beams to support the steel beams, the column base bottom plates are fixedly arranged at the lower ends of the steel columns, and the lifting lugs are fixedly connected with the upper sides of the steel beams to lift the steel beams. The prefabricating tool is simple in structure, high in strength, good in bending resistance and torsion resistance, high in shearing resistance and not prone to deformation, CV bottom end socket A-layer steel bars can be prefabricated into a steel bar module outside a site, the construction period can be greatly shortened, construction site management can be improved, the prefabricating tool is used for steel bar module hoisting, the weight of the steel bar module can be borne, and the construction efficiency is improved. Meanwhile, the steel bar position can be accurately positioned and fixed, and accurate butt joint of the steel bar module and the site reserved position is guaranteed.
本发明公开了一种核岛CV底封头A层钢筋模块化预制工装及施工方法，预制工装包括钢梁、钢柱、柱脚底板和吊耳，所述钢梁呈网格状结构且具有与CV底封头球面相适应的弯曲弧度，所述钢柱具有多个且与所述钢梁的下侧固定连接以支撑所述钢梁，所述柱脚底板固定设置于每个所述钢柱的下端，所述吊耳具有多个且与所述钢梁的上侧固定连接以吊运所述钢梁。该预制工装结构简单，强度高，抗弯、抗扭性能好、抗剪能力强、不易变形，能够将CV底封头A层钢筋在场外预制成钢筋模块，可大幅缩短建造工期，改善施工现场管理，且预制工装用于钢筋模块吊装，能够承受钢筋模块的重量，同时能够精准定位和固定钢筋位置，保证钢筋模块与现场预留位置准确对接。
