Construction knowledge of color steel tile press
1. Selection of self-tapping screws. When selecting the fixing screws, the fixing parts should be selected according to the service life of the structure, and pay special attention to whether the life of the covering material is consistent with the specified fixing part life. At the same time, the thickness of the steel purlin should not exceed the self-drilling of the screw Capability. The screws currently supplied can have plastic heads, stainless steel top caps or coated with a special durable protective layer. In addition, except for the screws for concealed buckle fixing, other screws are equipped with waterproof washers, and are suitable for lighting panels and special wind pressure The following conditions are equipped with corresponding special washers.
2. There are two types of fixing methods for the installation of color steel tile press: penetration and concealed buckle. Penetrating fixation is a common way to install color steel tile presses on roofs and walls, that is, use self-tapping screws or rivets to install The color plate is fixed on the support (such as purlin), and the penetrating fixing is divided into wave crest fixing, wave trough fixing or a combination of them. Concealed buckle concealed fixing is to fix the special concealed buckle matched with the concealed color plate to the support first On parts (such as purlins), the fixing method of the female rib of the color plate and the central rib of the hidden buckle is generally used for the installation of the roof panel.
3. The side and end of the color plate are overlapped. When installing each steel plate, its edge should be accurately placed on the previous steel plate and clamped with the previous steel plate until the two ends of the steel plate are fixed. A simple and effective method is to use a pair of clamping pliers to clamp the overlapped steel plates. When the steel plate is in place in the longitudinal direction, its ends, especially the upper end, need to be clamped with pliers to ensure that the steel plate One end is in place and the overlap of one end is also in the correct position to fix the steel plate. During the fixing process, the clamp should always clamp the steel plate longitudinally. Before installing the next steel plate, each steel plate is completely Fixing. Fixing starts from the center of the steel plate, and then extends to both sides to fix the lap side of the steel plate. For end lap joints, because the roof and wall profile panels are made by continuous processing, they can be transported The limited length of steel plate is supplied, usually without overlap, the length of the steel plate is enough to meet the needs of roofing.
