How to reinforce the lower part of the steel structure of the construction elevator on the roof of the non - air defense garage
Channel steel is a kind of carbon steel used in construction and machinery. It is a kind of complex section steel. Channel is mainly used in building structure, curtain wall engineering, machinery and equipment and vehicle manufacturing, etc.. It is required to have good welding, riveting and comprehensive mechanical properties. The raw material for producing channel steel is carbon steel or low alloy steel billet with carbon content not exceeding 0.25%. Finished channel steel formed by hot working forming, normalizing or hot rolling. Its specifications to waist height (H) * leg width (b) * waist thickness (d) of the MM number, such as 100*48*5.3, said waist height of 100 mm, leg width of 48 mm, waist thickness of 5.3 mm channel, or 10# channel. Waist high the same channel, if there are several different leg width and waist thickness also need to be on the right side of the model plus a B C, such as 25#a 25#b, etc..
According to the channel shape and can be divided into 4 kinds: cold bending equilateral channels, cold-formed non equilateral channel steel, cold rolled edge channels, the cold bending edge channelsIn accordance with the theory of steel structure, it should be the channel wing plate stress, that is, the channel should be standing, rather than lying.
The channel is divided into ordinary channel steel and light channel steel. Hot rolled ordinary channel specification is 5-40#. By the supply and demand sides of the agreement to provide hot rolled flexible channel specifications for 6.5-30#. Channel steel is mainly used in building structure, vehicle manufacturing, other industrial structure and fixed disk cabinet, etc..
