现今高支模的支撑一般采用钢管搭设,极少采用门式脚手架,但门式脚手架几何尺寸标准化、受力性能好、承载能力高,且施工中装拆容易、架设效率高,省工省时、经济适用,虽然整体稳定较差、变形较大,但只要措施得当,门式脚手架的安全性也能满足施工要求,且可产生较大的经济效益。 Today’s high formwork supports are generally made of steel pipes, rarely using portal scaffolds, but portal scaffolds have standardized geometric dimensions, good mechanical performance, high bearing capacity, and easy assembly and disassembly in construction, high erection efficiency, and saving time and labor. , Economical, although the overall stability is poor, large deformation, but as long as the proper measures, the safety of the portal scaffold can meet the construction requirements, and can produce greater economic benefits.
