自1968年第一块V形折板在北京铁路局昌平构件厂试制生产并首先在石油部门使用以来,发展极快。目前全国29个省、市、自治区都在不同程度上采用了这种板、梁合一的空间屋盖结构,路内不少单位也在仓库、站台雨棚以及其他生产技术作业房屋中采用。据不完全统计,全路已建成面积数十万平米,并在普通钢筋混凝土V形折板、大悬挑V形折板等方面进行了不少创新。实践证明,采用折板在某些条件下经济合理,便于施工,是一种相当有发展前途的屋盖结构。
Since 1968, the first V-shaped folding plate developed rapidly at trial production of Changping Component Factory of Beijing Railway Bureau and first used in the oil sector. At present, 29 provinces, municipalities and autonomous regions all adopt the space roof structure of such boards and beams in varying degrees. Many units in the road are also used in warehouses, platform shelters and other production technology operation houses. According to incomplete statistics, the entire road has been built an area of hundreds of thousands of square meters, and made a lot of innovations in ordinary reinforced concrete V-shaped folding, large cantilevered V-shaped folding plate. Practice has proved that the use of folding plate under certain conditions, economic and reasonable, easy construction, is a considerable roof structure of the future.
