Roof And Wall Panel Roll Forming Machine Heat Insulation Effect
Roof and Wall Panel Roll Forming Machine Heat insulation effect
First, the color plate in the south is generally designed as a single-layer color board. In order to reduce the heat of the solar radiation into the building, the insulation layer can be installed in the roof system when the roof panel is installed. There is a very simple, economic and effective method, namely before installing the roof steel purlin or lath with double reflection on foil membrane, this method also can be used as a steam isolation, to reduce the cohesion function. If the sagging depth of the film is allowed to reach 50~75mm between support, the air layer between the film and the roof plate will further enhance the insulation effect.
Second, the side and end of the color board connect. When installing each piece of steel plate, the side lap should be placed on the front plate accurately and clamped with the front plate until both ends of the steel plate are fixed. A simple and effective method is to use a pair of clamping forceps to clamp the plate of the residence. Along the longitudinal steel in place, its department especially the upper department need pliers clamp on part, which can ensure that at the end of the steel plate in place, and make the end of the lap joint is in a correct position, so as to hold the steel plate, in the process of fixed, clamp should always be in a vertical clamp plate. Before the next steel plate is installed, each plate must be completely fixed. The fixation must start at the center of the steel plate, then stretch to the sides, and then the final fixed plate. For end lap due to roof and wall plate shape is made with the method of continuous processing, therefore may according to the transportation conditions limit the length of the supply of steel plate, usually don't need a lap, steel plate length is enough to meet the needs of the roof laying.
Third, the choice of tapping screw. The fixed screw should be selected in accordance with the life of the structure, and the life of the overlying material shall be in accordance with the fixed service life. It is also noted that the steel purline thickness can not exceed the self-drilling capacity of the screw. The current supply of screws can have a plastic head, a stainless steel top cover or a special durable protective layer. In addition, other screws are equipped with a waterproof gasket, and corresponding special gaskets are provided for the light plate and special wind pressure. Fourth, the fixed way that the tile machine installation has the penetration type and the hidden type two kinds. Transmission is fixed roof and metope caigang equipment installation way of the most commonly used, which is self tapping screw or rivet color plate fixed on the supporting elements (such as purlin), transmission can be divided into fixed peaks fixed, fixed or their combination. Hidden-interlocking concealment type is fixed and dark buckle type color plate form a complete set of special dark buckle fixed on the supporting elements (such as purlin) first, the mother of choi ribs with dark buckle at the center of the rib of tooth fixed method, commonly used in the installation of roof panel.
