Shanghai professional steel structure loft design and construction

< r>: : R>The construction quality of reinforced concrete sandwich construction has problems and hidden dangers. During construction, the quality of reinforced concrete has become an important issue affecting the safety and durability of the structure. The quality problems of reinforced concrete construction can be summarized in several aspects, namely: material reasons, such as improper use of water, cement, sand, stone, admixtures, steel bars, lack of reinforcement glue, etc., or design reasons such as quality failure to meet requirements, etc. If the design safety is insufficient, the load selection is inappropriate, the structural layout and structure are unreasonable, calculation errors and other construction reasons, such as inaccurate ingredients, uneven mixing, too long transportation time, and pouring that does not meet the specifications, it is best to use steel pipe supports. Inadequate vibration, formwork deformation, slurry running, premature formwork removal and other environmental reasons, such as freezing damage, high temperature, high heat, corrosive media effects

Welding under the channel steel will not hold the board firmly when placing it, so it must be leveled after welding. It is best to use the inserting method for cutting grooves and corners. Welding on both sides of the flat and vertical sides is also very important. Rust prevention is also very important. It is easy for the rigid structure to absorb moisture but it is difficult for moisture to escape (especially the attic above the bathroom). It is best to do some rust removal before production. After applying the anti-rust paint on the steel, be sure to open the doors and windows to maintain ventilation and drain out the toxins in the paint.
