First, color steel machinery and equipment "target=_blank> mechanical equipment installation has two types of transmission and concealed concealed type. Penetration is the most common way to install roof and wall color steel equipment, that is, use The self-tapping screws or rivets fix the color plates on the support members (such as the purlins), and the penetrating fixing is divided into wave pin fixing, trough fixing or a combination thereof. The concealed concealed fixing is specially made with the dark button color plate. The method of fixing the concealed buckle on the support member (such as the purlin), and the fixing of the female rib of the color plate and the central rib of the concealed buckle is generally used for the installation of the roof panel.
Second, the side and end of the color plate overlap. When installing each steel plate, it should be placed on the front steel plate accurately and clamped to the previous steel plate until both ends of the steel plate are fixed. A simple and effective method is to use a pair of jaw clamps to clamp the overlapped steel plates.
Third, the color plates in the south are generally designed as single-layer color plates. In order to reduce the heat of solar radiation entering the interior of the building, the roofing system can be installed with insulation layers when installing the roof panels. There is a very simple, economical and effective way to apply a double-sided reflective foil film to the stringers or slats before installing the roofing steel. This method can also be used as a steam barrier to reduce agglomeration. If the film is allowed to sag between the supports by 50 to 75 mm, the air layer between the film and the roof panel will further enhance the heat insulation effect.
Fourth, the selection of self-tapping screws. When fixing screws are selected, the fixing parts should be selected according to the service life of the structure, and special attention should be paid to whether the life of the outer covering material is consistent with the life of the specified fixing parts. At the same time, note that the thickness of the steel string cannot exceed the self-drilling capacity of the screw. Screws currently available can be supplied with plastic heads, stainless steel "target=_blank> stainless steel top cover or coated with a special durable protective layer. In addition, the screws are equipped with waterproof washers for the screws, and for the lighting panels. Corresponding special gaskets are available for special wind pressure conditions.
Fifth, color steel pressing equipment - the installation of color plates is easier to master, and the handling of some details is more important. For the roof color board, the color board should be correspondingly closed at the roof and the eaves, in order to prevent rainwater from entering the roof more effectively. Where the roofing panel is on the ridge, the edge between the ribs of the steel plate can be folded upwards with a hemming tool. It is used on all upper ends of all grades below 1/2 (250) roof steel to ensure that water blown by the wind below the flooding or deck does not flow into the building.
Sixth, in the design of large-span and large-area workshops, in order to have sufficient brightness, lighting belts are often designed, usually arranged in the middle of each span. Although the setting of the lighting plate increases the degree of daylighting, it also increases the heat transfer of the sun and increases the temperature inside the building.
