Roll Forming Machine Operational skills
First, the selection of self-tapping screws. Fixed screws should be selected according to the service life of the structure, and special attention should be paid to whether the life of the overlying materials is consistent with that of the specified fasteners. Also note that the thickness of the steel purlin should not exceed the auger capacity of the screw. The screws currently supplied may have plastic heads, stainless steel caps or special durable protective coatings. In addition, other screws are equipped with waterproof washer except those used for dark fastening, and corresponding special washer is provided for the case of light plate and special air pressure.
Second, the side and end lap of the color plate. When installing each piece of steel plate, the side lap shall be accurately placed on the front plate and clamped with the front plate until both ends of the plate are fixed. A simple and effective method is to use a pair of clamping pliers to clamp the housing lap steel plate separately. When the steel plate is placed along the longitudinal direction, the end part, especially the upper part, shall be clamped with pliers, so as to ensure the positioning of one end of the steel plate, and the lap joint of one end shall be in the correct position, so as to fix the steel plate.
Sixth, color plate installation is easy to master, and some details of the treatment is more important. For the roof use of color panels in the roof and eaves should be in the corresponding work of edge collection, its purpose is to more effectively prevent rainwater from entering the roof.
Third, in the design of large-span and large-area workshop, in order to have enough brightness, there are lighting belts usually designed, which are generally arranged in the middle of each span. The lighting panel setting increases the lighting intensity, but also increases the heat transfer of the sun, increasing the temperature in the building.
Fourth, in the south of the color plate is generally designed as a single layer of color plate, in order to reduce solar radiation heat into the inside of the building, when installing roof board, can install heat insulation layer in the roof system. There is a very simple, economic and effective method, that is, before installing roofing sheet steel plate, on purlin or plank top spread double sided reflex foil film, this kind of method also can serve as steam segregation, in order to reduce agglomeration action. If the sagging depth of the film between the supports is allowed to reach 50~75mm, the air layer between the film and the roof panel will further improve the insulation effect.
Fifthly, the fixed way of the equipment installation of the tile press includes two types: penetration type and hidden type. Penetration fixation is the most common way of installing roof and wall color steel equipment. It USES self-tapping screws or rivets to fix color plates on supporting parts (such as purlins). Penetration fixation can be divided into crest fixation, trough fixation or their combination. Blind fastening is the special fastener that will match with the black fastener color plate is fixed on the supporting part (such as a purlin) first, the fixed method of the female rib of color plate and the central rib teeth of the black fastener, it is commonly used for the roof plate installation.
