折迭式预应力混凝土V形折板是近十年来得到发展应用的板架合一结构,具有体型简洁、传力路线短、灌缝后整体刚度和抗震性能好等优点。同时制作简便,可迭层生产,节约三材,便于采用工业化方法制作和施工,具备了发展为工业化建筑体系的基本条件。我国从一九六九年开始采用以来,已在二十九个省市自治区使用,据不完全统计,建筑面积达一百多万平方米,积累了一 Folded prestressed concrete V-shaped folding plate is a plate-in-one structure that has been developed and applied in the past ten years. It has the advantages of simple body shape, short force transmission route, overall stiffness after grouting, and good anti-seismic performance. At the same time, it is simple to produce, can be laminated production, save three materials, easy to use industrial methods of production and construction, with the basic conditions for the development of industrial building systems. Since its adoption in 1969, China has been used in 29 provinces, municipalities, and autonomous regions. According to incomplete statistics, the building area has reached more than 1 million square meters and has accumulated
