The specifications and quality of sandwich plates and auxiliary materials must meet the design requirements; Inspection method: check the factory certificate and inspection report; In addition, Jinan Caigang Sandwich Panel Factory reminds you that the connection and sealing treatment of sandwich panels must meet the design requirements, without leakage; Test method: observation and inspection and test after rain or watering.
Requirements for appearance quality of sandwich panel: the surface defect of the panel, the quality of the core panel, the notch, the flatness of the panel; No obvious concavity, warpage and deformation; Surface cleaning; Uniform color; No glue mark or oil stain; No obvious scratches, bumps, scars and other surfaces are clean, without glue marks and oil stains. Except for the curling and cutting edges, the rest of the board surfaces are free of obvious scratches, bumps, scars and other cuts. The cut surface is neat and free of burrs. The board edge is free of obvious warping, degumming and waviness. The panel should be bent inward. The core plate cut surface should be neat and free of large peeling. There is no obvious gap between the joints between blocks. The bonding between the panel and the core material is firm and the core material is dense.
During the construction of roof panel, avoid scratching the outer steel plate of the roof; During roof construction, sundries shall be cleaned in time, and there shall be no sundries blocking water outlets, inclined ditches, etc; During roof construction, the wall and other finished products shall not be polluted; The stacking site of color steel sandwich panels should be flat and solid, and easy to drain surface water. Stacking shall be carried out in layers, and skids shall be added along the length direction. It is not allowed to move the overlapped steel plate during manual handling, and special lifting tools shall be used for mechanical lifting.
During construction, the plates shall be fixed firmly, and the joints must be constructed in strict accordance with the design requirements to ensure that the joints are tight, and the bolts shall be tightened. The sealing strip between plates shall be continuous, the rivet and lap joint must be sealed tightly with sealing strip, and the joint shall be tight to prevent water leakage from the roof panel; During construction, the line shall be hung and the board shall follow the line to ensure that the cornice is straight and the cornice is consistent; The surface of gutter and inclined gutter shall be flat, the slope shall be uniform and consistent, and meet the design requirements; The roof shall be flat, the upper and lower corrugations shall be consistent, and the overlapping length shall meet the requirements to avoid uneven cornice and poor surface flatness; c) The slope elevation control point shall be set during the roof slab construction, and the slope shall be accurate during the paving to ensure smooth drainage.
Safe operation requires that when installing the roof panel, the ladder used must be stable and reliable. When the wind force exceeds four or more, the roof operation shall be stopped; Electrical equipment and lines shall ensure power safety. Electric tools and equipment shall be started under no-load condition. Operators shall wear insulating gloves and insulating rubber shoes.
Necessary rain-proof, moisture-proof, sun-proof, frost-proof, fireproof and other measures shall be taken for the storage of materials at the construction site according to the material properties; Operators must wear safety helmets and fasten safety belts for edge operations. Environmental protection measures The cutting shed with sound insulation and noise reduction functions shall be set up for the roof panel cutting.
