Steel safety skills
Introduction
Foshan Steel structure dominated by steel production, is one of the main construction of the structure type. Steel is characterized by high strength, light weight, stiffness, it is used to create large-span and ultra, ultra heavy construction material particularly suitable; homogeneous and isotropic material is good, is aspiring elastomer, usually works best suits simply assumed mechanics; material ductility, toughness, and can have a large deformation, can be an excellent way to withstand dynamic loads; construction of short duration; their high degree of industrialization, can be a high degree of mechanization of specialized production; high precision, high efficiency , sealed good, it can be used to create a tank, tanks and transformers. Its drawback is poor fire resistance and corrosion resistance. Mainly used for heavy-duty load-bearing skeleton workshop by dynamic loads of the plant structure, plates and shells, towering tower and mast structures, bridges and warehouses and other large span structures, high and ultra-high-rise construction and so on. Steel should discuss the future of high-strength steel, greatly improving its yield point strength; addition to rolling new varieties of steel, such as H beam (also known as wide-flange beam) and a T-shaped steel and steel sheeting, etc. to accommodate the large span structures and require super high-rise construction. Steel is divided into light steel and heavy steel. Determined that no one uniform standard, a lot of experienced designers or project managers are often not fully say it, some of the data can be summarized think and discrimination.
There are no thermal bridges other light steel systems, steel construction itself is not energy efficient, and this special skill with clever connections to solve the problem of hot and cold bridge construction; small truss structure of the cable from the wall and down the water pipes crossing, construction decoration are convenient; unparalleled energy efficiency is the world's only one in cold-formed steel construction of homes built seven layer system.
Although China has a pre-eminent achievements in the iron structure, but because of 2000 years of feudal bondage, science developed, therefore, the level of iron to build long-term stay in the matter. Until the 19th century, before the beginning of the use of modern steel.
After new China establish, steel applications has been greatly developed, both in the quantity or quality are far more than before. In skills such as design, production and installation have reached a higher level, to master a variety of messy construction materials design and construction skills, the country has been creating a lot of size and structure of the clutter of endless steel plant, large-span steel structure of civil construction and railway bridges, etc., etc. Great Hall of the steel roof trusses, Beijing and Shanghai stadium steel grid, Shaanxi Museum of Terracotta horses commission three-hinged steel arch and the Bird's Nest in Beijing and so on.
Light steel floor from cold-formed steel or composite beam, floor OSB structural panels, support, connectors and other components. The materials used are OSB, cement fiberboard and plywood. In these lightweight floor surface can withstand 316 to 365 kg of load per square meter.
Matt construction of light steel structure residence floor system weighs only one-quarter to one-sixth of the country's traditional concrete floor systems, but its floor structure than ordinary concrete slab height of 100 to 120 mm high.
