Roof pressure tile molding machine installation process precautions
First, in the southern color plate is generally designed for single-layer color plate, in order to reduce the heat of solar radiation into the building interior, in the installation of roof panels, you can install the insulation system in the roof system. There is a very simple, economical and effective way to lay a double-sided reflective foil film on a purlin or slab before installing a roofing plate. This method can also be used as a steam barrier to reduce agglomeration. If the dropping depth between the supports is 50 to 75 mm between the supports, the air layer between the film and the roof panel will further enhance the insulation effect.
Second, the side and end of the color plate overlap. When installing each steel plate, it should be placed on the front of the steel plate, and with the previous piece of steel clamping, until both ends of the steel plate are fixed so far. A simple and effective method is to clamp the overlapped steel plate with a pair of clamp tongs. When the steel plate is in the longitudinal direction, its end, especially the upper end, must be clamped with the pliers to ensure that the end of the steel plate is in place and the overlap at one end is in the correct position to secure the steel plate. During the fixing process, the clamp should always be sandwiched in the longitudinal direction. Before installing the next piece of steel, each steel plate must be fully secured. The fixing must start at the center of the steel plate and then extend to both sides, and finally fix the lap of the steel plate. For the end lap, since the roof and the wall profile are made by continuous machining, the steel plate can be supplied at a length limited by the transport conditions, usually without lap, and the length of the plate is sufficient to meet the needs of the roofing The
Third, the choice of tapping screws. Fixing screws should be selected in accordance with the structure of the service life of the fixed parts, and pay special attention to the life of the outer cover material and the specified fixture life is consistent. At the same time pay attention to the thickness of steel purlins can not exceed the screw self-drilling ability. The currently supplied screws can be supplied with plastic head, stainless steel cover or coated with a special durable protective layer. In addition, in addition to the dark buckle fixed screws, the other screws are equipped with waterproof washers, and for the lighting board and the special wind pressure are equipped with the corresponding special washers.
Fourth, the pressure gear machine equipment installed in a fixed way through the penetrating and concealed two. Penetration is the most common way to install the roof and wall color steel equipment, that is, with self-tapping screws or rivets will be fixed on the support plate (such as purlins), penetrating fixed into a crest fixed, trough fixed or Their combination. The concealed fastening is a fixed method that is fixed to the support (such as purlins), which is a special fit with a dark button color plate. Panel installation.
Fifth, the installation of color plate easier to grasp, and some of the details of the treatment is more important. For the roof with a color plate should be in the roof and the roof of the color board will be the corresponding edge of the work, the purpose is to more effectively prevent the rain into the roof.
Sixth, in the design of large span and large area of the plant, in order to have enough brightness, often designed with a lighting belt, usually arranged in the middle of each span. Although the installation of the lighting board increased the degree of light, but also increased the heat transfer of the sun, increasing the temperature inside the building. In general roof and pan board installation operations, tapping screws, drills, hand saws, or other operations will leave metal debris on the roof or adjacent areas, these debris and other debris (rivets, Nails, screws, etc.) must be removed from the roof, water board, gutter, etc. as soon as possible. This work should be done as a daily end. Especially after the completion of the entire roof installation, the need for this work. If this work is neglected, the metal debris will be oxidized and the surface of the steel sheet will become stained.
