    随着我国钢产量的增长及国家对钢结构产业政策的调整,钢结构建筑的兴建日益增多.轻型钢结构建筑以其自重轻、抗震性能好、施工快和污染小等独特的发展优势,已经广泛应用于工业厂房、库房、体育馆、展览管等工程项目中。
    With the increase of steel output and the adjustment of national policy on steel structure industry, the construction of steel structure buildings is increasing day by day. Light steel structure buildings have been widely used in industrial buildings, warehouses, gymnasiums, exhibition pipes and other projects because of their unique development advantages such as light weight, good seismic performance, fast construction and low pollution.
    1.fun88安装屋面的构造 fun88安装屋面由结构层、保温层和面板层构成,结构层以“C”型钢和“Z”型钢为主;保温层现场填充时多为玻璃丝棉、岩棉,当保温层为聚苯或聚氨酯时,通常与乐天堂棋牌正版在工厂内预先乐天堂老虎机成型(称为fun88安装乐天堂老虎机夹芯板);面板层主要有彩色压型钢板、fun88安装乐天堂老虎机夹芯板。 依据面板层的选用不同,fun88安装屋面可大致分为单层乐天堂棋牌正版屋面、双板现场乐天堂老虎机屋面和fun88安装乐天堂老虎机夹芯板屋面。

    1. The structure of color steel roof is composed of structural layer, thermal insulation layer and panel layer. The structural layer is mainly composed of "C" steel and "Z" steel. The thermal insulation layer is mostly filled with glass wool and rock wool. When the thermal insulation layer is polyphenylene or polyurethane, it is usually pre-formed with color steel sheet in the factory (called color steel composite sandwich panel). The panel layer mainly consists of color pressed steel sheet and color steel composite. Close the sandwich board. According to the choice of panel layer, the color steel roof can be roughly divided into single-layer color steel plate roof, double-plate field composite roof and color steel composite sandwich panel roof.

    2.面板选材及连接形式 fun88安装屋面一般采用fun88安装压型板或fun88安装乐天堂老虎机夹芯板。fun88安装压型板是采用镀锌(或镀铝锌)基板涂覆彩色涂层后形成的彩涂板轧制成型。单层fun88安装压型板重量轻、强度高、制作安装方便,但导热系数大,隔音效果差;对有保温、隔音要求的屋面,可采用双层fun88安装压型板中间填充保温材料(如玻璃丝棉、岩棉等)或采用fun88安装乐天堂老虎机夹芯板,fun88安装夹芯板为双层乐天堂棋牌正版与保温材料在工厂通过粘结剂预先乐天堂老虎机成型,因此具有抗弯刚度高、整体性能好等优点,使用范围越来越广。
    2. Selection of panel materials and connection forms of color steel roofs generally use color steel profiled plates or composite sandwich panels. Coloured steel profiled sheet is rolled with colour coating on galvanized (or aluminized) substrates. Single-layer color steel profiled sheet is light in weight, high in strength and easy to manufacture and install, but its thermal conductivity is high and its sound insulation effect is poor. For roofs with insulation and sound insulation requirements, double-layer color steel profiled sheet can be used to fill insulation materials (such as glass wool, rock wool, etc.) or composite color steel sandwich sheet. The color steel sandwich sheet is pre-formed by binder in factory. Therefore, it has the advantages of high flexural stiffness and good overall performance, and has been used more and more widely.
