拱结构是一种受力性能好的结构形式。折迭式V形折板结构,是一种新的屋盖结构。两种结构型式都有各自的明显优点。前者受力性能好,后者预制方便、自重轻。预制小平板拼装式折板落地拱(简称折板拱)是在吸取上述两种结构型式各自优点的基础上而发展起来的一种新结构型式。它是用一种单一构件以“预制为手段、整体为目的”、按照合理的几何图形组成较大的空间,从而达到经济合理的目的。并以此满足一部分较大跨度建筑的需要。为了上述目的,我们于1978年在徐州市蔬菜公司的支持下,为该公司设计了一幢容量一万吨、建 Arch structure is a structural form with good mechanical properties. The folding V-shaped flap structure is a new roof structure. Both types of structure have their own distinct advantages. The former has good stress performance, and the latter is easy to prefabricate and light weight. The prefabricated small flat-panel folded floor arch (abbreviated as the arch) is a new type of structure developed on the basis of the advantages of the above two structural types. It is to use a single component to “prepare as a means, the overall purpose”, according to a reasonable geometric composition of a larger space, so as to achieve economic and rational purposes. And to meet the needs of some of the larger span buildings. For the above purpose, we designed a capacity of 10,000 tons for the company under the support of Xuzhou Vegetable Company in 1978.
