V形折板屋盖是许多平板组成折叠式的空间结构。其特点是屋架、屋面板和防水层合一,构成板架统一体。我国在采用钢筋混凝土折板或预应力钢筋混凝土折板作为工业厂房和其他建筑物屋盖已为普遍。它具有结构重量轻、刚度大、造型美观、抗震性能好,便于安装及比较先进的经济技术指标等优点。钢丝网水泥V形折板具有更薄、更轻、施工更为简便的特点。我厂热加工广房原采用轻钢石棉瓦屋盖体系,由于铸钢件热加工有害气体的浸蚀造成 The V-shaped flap roof is a folded space structure composed of many flat panels. It is characterized by a combination of roof trusses, roof panels and waterproof linings that form a unitary body. In China, the use of reinforced concrete folding plates or prestressed reinforced concrete folding plates as the roof of industrial plants and other buildings has become common. It has the advantages of light weight, high stiffness, beautiful appearance, good anti-seismic performance, easy installation and comparatively advanced economic and technical indicators. Steel wire mesh V-shaped flaps are thinner, lighter and easier to construct. Our factory heat processing Guangfang used light steel asbestos roof system, due to the corrosion of the harmful gases of hot steel processing
