GBF高强薄壁管无梁楼盖施工技术探讨

On GBF high strength thin-wall pipe girderless floor construction technology

针对高强薄壁管混凝土振捣不密实、GBF管上浮及位移、易损坏的质量通病,阐述了GBF管现浇混凝土空心楼盖施工工艺和施工要点,并提出了施工控制措施,从而有利于该技术的推广应用。

Aiming at the quality common diseases of the high strength thin-wall pipe,such as concrete vibrating sterilitas,GBF pile float upward,settlement and easy to destroy,the author describes the construction technology and construction points of the GBF pile cast-in-place concrete follow floor,and provides construction control measures,thus providing benefit for population and application of this technology.
