曲面混凝土建筑物模板的支撑,常用的有两种:一是木制拱卷。二是型钢固定支撑。采用木制拱卷,首先需要大量的木材,而且是一次性的消耗,无法周转,也不符合“以钢代木”的方针,所以不但企业的经济效益不高,而且社会效益也不高。其次是,这种支撑,一般加工量不但大而且加工困难,势必拖长模板工程的工期。第三,由于拱卷 There are two types of support for curved concrete building formwork: one is a wooden arch. The second is fixed steel support. The use of wooden arched scrolls requires a large amount of wood first, and it is a one-time consumption that cannot be turned around. It does not conform to the policy of “using steel instead of wood”. Therefore, not only is the economic benefit of the enterprise low, but also the social benefit is not high. Second, this kind of support is generally not only of large processing volume but also difficult to process, which will inevitably delay the construction period of the formwork project. Third, due to the arch volume
