Steel lifting technology and lifting program for steel structure building. Fifth-- Steel lifting construction safety requirements
Common Problems and Solutions in Steel Structure Construction Structural dead bending deformation, the general use of mechanical correction method.
Due to its own advantages, steel structures are widely used in modern buildings such as bridges, industrial plants and high-rise buildings.
Logo is the difference between the steel material, the specification of the mark, the main description of the steel supplier for steel structure hangar, grade, inspection lot number, size, size, level, net weight and so on.
Compared with ordinary steel, special steel has a higher strength and toughness, physical properties, chemical properties, biocompatibility and process performance.
Second.the classification of steel for prefabricated steel structure Steel is iron and carbon alloy with carbon content between 0.04% and 2.3%.
Before introducing the classification of steel structure building, please briefly introduce the basic concepts of ferrous metals, steel and non-ferrous metals.
Roofing works for sub-project acceptance, the quality should meet the following requirements:
The base positioning axis and the support steel cylinder surface elevation exceed the allowable deviation of the specification.
