If the lighting board is classified according to the material, it can be mainly divided into polyester lighting board and solid board, etc.; if it is classified according to the shape, it mainly includes flat lighting board and curved lighting board.
Of course, different lighting panels have different installation methods. The polycarbonate lighting panels are mainly fixed by aluminum fasteners; while the corrugated lighting panels are connected and fixed by brackets or screws. Then glue sealing is required. Under normal circumstances, the lighting board is set in the middle of the span.
When the lighting board is connected with self-tapping screws, remember that it must have a cover plate. Because the sun board has a relatively large deformation in cold and heat, it is more often directly cut by self-tapping screws. Therefore, sunlight When the board is driven in with self-tapping screws, the holes should be opened larger. When installing the daylighting board, it is also important to consider the flexibility of the daylighting board.
If the lighting board is guaranteed to be within 12m, there is no need for lap joints, and if it exceeds 12m, lap joints must be carried out. The length of the lap joints should be guaranteed to be between 200mm-400mm, and two coats of sealant should be applied to the lap joints , if it is for horizontal lap joints, it does not need any trimming, but for longitudinal laps, it needs to be kanban-shaped. Ordinary profiled steel plates do not need to be considered for trimming, and they are directly combined with color plates. Use self-tapping screws to fix it, and then apply a layer of sealant. The occlusal plate must be trimmed.
