高层建筑的楼板通常为现浇钢筋混凝土结构,在施工中如何改善模板的支承体系、缩短支模时间,这在高层建筑主体结构施工中越来越受到工程技术人员广泛的关注。随着高层建筑施工技术的不断发展,楼板支撑的种类也越来越多,同时也不断地得到改善,其中使用飞模工艺是较为理想的一种,它具有安装简便、便于操作、安全可靠、减轻劳动强度、提高工效等优点。 1 飞模的构造与制作 飞模由面板11、承重支架1、纵梁3、横梁5、挑梁4、接长管9、调节螺栓7与8等组成(图1)。承重支架1是由钢管焊成的双支柱管架,支柱为外径
The floors of high-rise buildings are usually cast-in-place reinforced concrete structures. How to improve the support system of the formwork and shorten the time for supporting the formwork during construction is more and more widely concerned by engineers and technicians in the construction of high-rise building main structures. With the continuous development of high-rise building construction technology, there are more and more types of floor support, and they are constantly being improved. Among them, the use of flying mode technology is an ideal one. It is easy to install, easy to operate, safe, and reliable. Reduce labor intensity, improve ergonomics and other advantages. 1 Structure and production of a flying mold The flying mold consists of a panel 11, a load-bearing bracket 1, a longitudinal beam 3, a cross beam 5, a cantilever beam 4, an extension tube 9, an adjusting bolt 7 and 8, etc. (Fig. 1). The load-bearing bracket 1 is a double-pillar pipe frame welded by a steel pipe, and the pillar has an outer diameter.
