我们通过施工实践,总结了以往脚手钢管搭设排架支撑现浇混凝土框架、屋面的经验,成功地采用φ50毫米脚手钢管代替全部和局部木模支撑结构,不仅解决了木材紧张的问题,而且节省了大量的人工,提高了模板的使用周转率。脚手钢管代替木模支撑结构的特点是: Through the practice of construction, we have summarized the experience of the scaffolding steel pipe supporting the cast-in-place concrete frame and roof in the past. We successfully used φ50 mm foot steel pipe to replace all and local wood mold support structures, not only solving the problem of wood tension, but also Save a lot of labor and increase the use of template turnover. The characteristics of the foot steel tube instead of the wood mold support structure are:
