我厂于1981年开始试制三种类型(整体板、缺翼整体板、半体板)、三种尺寸(4、3.6、3.3米)的预应力钢筋混凝土带肋屋面板。这种板是集檩条、望板和挂瓦条于一体的多用板,具有质轻、价廉、坚固、美观和节约木材的优点,当年已投入小批量生产。这种板的板高均为17厘米,宽度视板型不同而异。其中:整体板为双倒T型,宽0.65米,用于除屋脊处外的屋面部分;缺翼整体板,用于屋面起脊处,宽0.5米;半体板为整体板的一半,宽0.325米,用于屋面余数部分,即作补充板用。这种板是三合一的组合体,具有多种功能:作起脊屋面时,装好屋面板后可直接挂
In 1981, our factory began trial production of three types of prestressed reinforced concrete ribbed roofing panels (Integral plate, Winged monolithic plate, Half plate) and three sizes (4, 3.6, and 3.3 meters). This board is a multi-purpose board that integrates a purlin, a checkerboard, and a battens. It has the advantages of light weight, low cost, solidity, beauty, and wood saving. It has already been put into small batch production. The board height is 17 cm and the width varies depending on the board type. Including: The overall board is double-inverted T type, 0.65 meters wide, used in roofing except for the ridge; the winged monolithic board is used at the ridge of the roof and is 0.5 meters wide; the half board is half the width of the overall board, 0.325 meters, used for the remainder of the roof, that is, for supplementary boards. This kind of board is a three-in-one combination and has multiple functions: When the roof is raised, the roof panel can be directly attached.
