1.floor deck roll forming machine used in combination plate pressure plate net thickness not less than 0.75mm, the best control in 1.0mm or more. For ease of pouring concrete, requiring pressure plate average width of not less than 50mm, set in the tank when the cylinder head studs, the pressure plate Total height (including indentation included) should not exceed 80mm.� 2.floor deck roll forming machine in the larger sections and concentrated loads should be configured to open additional reinforcement around the hole, when fire rating is high, you can configure additional longitudinal reinforcement. To improve the combined effect of a combination plate, smooth opening pressure plate, should be cross-cutting.� 3.floor deck roll forming machine combined board should be set up distribution steel mesh, reinforced in both directions with the distribution rate should not be less than 0.002 Jin.� 4.floor deck roll forming machine continuous composite plate negative moment cracking width, indoor under normal circumstances should not exceed 0.3 mm, indoor or outdoor high ambient temperatures should not exceed 0.2mm. Continuous composite plates by simply supported plate design, bearing negative reinforcement cross-sectional area of not less than 0.2% of the concrete section.??More: http://www.xinnuochina.com/floor/70.html
