When drilling, the roof panel should be drilled through vertically with the purlin, and when fixing the bolt, the waterproof sealing washer should be padded first, and the rubber gasket plate and the stainless steel gland are sleeved and tightened with force;
When laying the board, the board is connected with the board with rivets, and the distance is generally 100mm 500mm. The long lap joint of two plates should be placed a long sealing strip, and two sealing strips should be placed at the end, and the sealing strip should be continuous without interruption. The sandwich panel should be fixed with galvanized bolts with waterproof washers, the fixing point should be located on the wave crest, and all leaking screws should be protected by sealing materials, and there should be no leakage.
After the bolt is tightened, the lap joint of the two plates is sealed tightly with silicone sealant;
After the plate is laid, the longitudinal (longitudinal) lap joint of two plates should also be connected with pull rivet, and the pull rivet used is all sealed with silicone sealant, and protected with metal or plastic gland;
Requirements for fixed position: self-tapping screws and rivets are set at the crest when used for roofing; When used for wall surface, it is located in the valley;
Roof ridge laying: at first, along the ridge line on the adjacent two purlins to lay the ridge board, place the roof plate on the ridge board, the roof panel, the ridge board, the purlin are fixed with bolts; Secondly, the requirements for the lap of the sandwich panel roof formed along the ridge of the two-slope roof panel (mm) Item 1 2 3 4 5 Item Sandwich panel transverse lap Sandwich panel longitudinal lap Sandwich panel protrudes from the wall length Sandwich panel extends into the eaves gutter Lap length of sandwich panel and flashing Lap length not less than one slope 200 200 150 200 Table 65-2 Inspection method Observation Inspection with ruler Inspection with ruler Inspection with ruler inspection.
Spraying test: After the roof panel is nailed, spraying water can be used to do the spraying test, the watering time is not less than 2h, check whether there is leakage on the roof, if the problem is found, the leakage point should be repaired in time.
1. All use color steel sandwich panels to make indoor ceilings? I don't understand what it means, is it done indoors? The color steel plate ceiling can not be used with a hanging rib keel, to use 60X60 square tube welding or C-shaped steel, and then put the color steel plate on it to fix it with the eye tail self-tapping.
1. Increase the cross-section reinforcement method.
The construction process of this method is simple, adaptable, and has mature design and construction experience. Apply. >>>More
(1) According to the design elevation of the ceiling, the line should be clear and accurate, and the allowable deviation of its level should be 5mm. >>>More
After the installation of each ceiling color plate, it is necessary to fix the color plate and the keel with screws before the installation of the next color plate, and the plate and the plate should be filled as much as possible to ensure the clean room environment in the later stage. The indirect seams of the four color plates should be kept in the crosshairs, so as to facilitate the aesthetics after gluing in the later stage. For the roof joint where the wall panel is located, it can be used as an adjustment joint for the board joint, and the uniformity of the roof joint in other areas of the room can be ensured by adjusting the roof joint in this area. >>>More
The elastic line is copied out of the horizontal point on each wall (column) corner in the room with a level meter (if the wall is longer, a few points should be copied in the middle), and the horizontal line is popped up (the horizontal line is generally 500 from the ground), from the horizontal line to the design height of the ceiling, the horizontal line is popped up along the wall (column) with the pink line, which is the lower skin line of the ceiling grille. At the same time, according to the ceiling plan, the position of the main keel is ejected on the concrete roof. The main keel should be divided from the center of the ceiling to both sides, the maximum spacing is 1000, and mark the fixed point of the boom, the fixed point spacing of the boom 900 1000. >>>More
