Steel structure construction process description 

 1, the steel is in accordance with the light steel structure design, in line with national light steel design specifications. 
 2, the main use of steel I-beam spacing of 800mm, the main beam with embedded iron welding over 360 degrees, between the main beam with embedded iron shop for 0.69 composite slabs, composite slabs of concrete floating ceramic (ceramic on the surface and flush beam), the top ceramic rod with 6 #, the formation of high strength reinforcement network. 
 3, the floor plate used between the bottom of the beam angle, distance 688mm (or so). 
 4, steel construction specifications: GB50017-2003 
 5, the main load: 800mm spacing embedded parts embedded with pieces of each of four chemical anchors. High-strength chemical anchor bearing shear force: 3.5 tons / root, (diameter: 12mm) 
 Activities load 0.15TN / m2. 
 200-350 kg per square meter base pressure. 
 Second, the basic construction process: 
 Rust - Super level - fixed embedded parts - the main beam OK - Combination floor installation - filled with ceramic - reinforcement of the installation and welding - welding of anti-rust treatment - concrete cushion 
 1, Rust: The I-beam, angle iron to remove the rust. Even with the high quality anti-rust paint brush. 
 2, Super Level: The level of control over the level of the steel level (no vertical pitch). 
 3, embedded parts fixed: drilling in the bearing wall surface, the embedded iron with a chemical anchor fixed to the wall, each embedded with 4 pieces of high-strength chemical anchor. 
 4, the main beam to determine: the full 360-degree main beam welding and embedded iron. 
 5, is installed between the main beam composite slabs, composite slabs with additional angle iron at the next (second loading) 
 6, filled with ceramic: the ceramic, cement and sand mix well filled to the floor board, the surface of the upper surface flush with the main beam. 
 7, ceramic top of the rod with 6 # network composed of stretching, stretching between the network and the main beam welding. 
 8, the main beams and angle irons to be after all the welding, using high-quality anti-rust paint brushing all the weld on the uniform. Be the main frame without rust holes. 
 9, with 3cm thickness of concrete will cover all 6 # wire rod, concrete surface smooth and no debris. 
 Note: The steel girders were all to become useful, the main beam without welding.
