What are the adiabatic materials commonly used in construction?
According to the "construction construction fastener steel scaffolding safety technical specifications" JGJ according to 30 - II 0 Yiyi: 3 According to the scaffolding steel pipe should use the current national standard "straight seam welded steel pipe" GB / T according to three paint 9 or " Low-pressure fluid transmission with welded steel pipe "GB / T three 09 according to the provisions of the Q 2 3 5 ordinary steel; steel pipe quality should be consistent with the current national standard" carbon structural steel "GB / T paint 00 Q 2 3 5 steel Provisions Third, according to II scaffolding steel pipe should be used Φ four bar Three × three Lu steel pipe Each tube of the central part of the section of the lamp lamp Juhua Donghua maximum quality should not be greater than II 5 bar kg The fastener is the connection between the steel pipe and the steel pipe, in the form of three, namely, the right angle fastener, the rotating fastener, the butt fastener right angle fastener: for the connection of two vertical intersecting steel pipe, it relies on the fastener and The friction between the steel pipe to pass the load Rotary fastener: for two arbitrary angle of the intersection of steel pipe connection Butt fasteners: for two steel pipe docking long connection
), inorganic (such as perlite cement board, DY Inorganic insulation wall insulation system, foam cement board, composite silicate, rock wool, autoclaved aerated concrete block, the traditional insulation mortar, etc
Cast iron pipe is mainly connected to different ways, divided into W, A, B type
