For the roof color plate, the color plate should be closed at the roof and eaves to prevent rainwater from entering the roof more effectively. At the ridge of the roof, the outer plate of the roof can fold up the chassis between the end ribs of the steel plate with the edge closing tool.

彩鋼板用于所有坡度低于二分之一屋面鋼板的上端，以保證在泛水板或蓋板下方由風(fēng)吹入的水不會(huì)流入建筑之中。

The color steel plate is used for the upper end of all roof steel plates with a slope of less than one-half to ensure that the water blown by the wind under the flashing plate or cover plate will not flow into the building.

穿透式固定是彩鋼板安裝的更常用方式，即用自攻螺釘或鉚釘將彩板固定在支撐件(如檁條)上，一般用于屋面板的安裝，彩板的側(cè)向和端部搭接，安裝每一塊鋼板時(shí)，應(yīng)將其邊搭接準(zhǔn)確地放在前一塊鋼板上，并與前一塊鋼板夾緊，直到鋼板的兩端都固定為止。一種簡(jiǎn)單而有效的方法是用一對(duì)夾口鉗分別夾住所搭接的鋼板。

Penetration fixation is the most commonly used method for installation of color steel plate, i.e. fixing color steel plate on supporting parts (such as purlin) with self tapping screws or rivets, which is generally used for installation of roof panel. The side and end of color steel plate are overlapped. When installing each steel plate, the edge overlap shall be accurately placed on the previous steel plate and clamped with the previous steel plate until both ends of the steel plate are fixed. A simple and effective method is to clamp the overlapped steel plates with a pair of pliers.

固定螺釘選用時(shí)應(yīng)該按照結(jié)構(gòu)的使用壽命選擇固定件，而且特別注意外覆材料的壽命與指定的固定件壽命是否一致。

When selecting fixing screws, the fixing parts shall be selected according to the service life of the structure, and special attention shall be paid to whether the service life of the covering material is consistent with that of the specified fixing parts.

同時(shí)注意鋼檁條厚度不能超過(guò)螺釘?shù)淖糟@能力。目前供應(yīng)的螺絲可帶有塑料頭、不銹鋼頂蓋或涂有特殊的耐久保護(hù)層。

At the same time, the thickness of steel purlin shall not exceed the self drilling capacity of screw. The screws currently available can have plastic heads, stainless steel covers or be coated with a special durable protective coating.

另外，除暗扣固定用螺釘外，其他螺釘均帶有防水墊圈，而且針對(duì)采光板和特殊風(fēng)壓下的情況均配有相應(yīng)的專用墊圈

In addition, in addition to the screws for snap fastening, other screws are provided with waterproof washers, and the corresponding special washers are provided for the lighting panel and special wind pressure
