What are the rules of several channels? 33rd floor
The channel steel floors of a 33-story building are generally on the 3rd floor, 10 floor, 17 floor, 24th floor and 3 1 floor, because one channel steel floor is usually built every 7th floor.
The channel steel layer of commercial housing is generally on the first floor, and there may also be a channel steel layer interlayer. The channel steel layer is constructed by a plurality of channel steels, and the channel steels are long steel with a groove-shaped cross section.
Actually, there's nothing wrong with using it as a cubicle. There is also a layer of channel steel in the scaffolding from the seventh floor to the eighth floor of the commercial house. In some places, the first floor is a channel steel floor, but the house on the first floor is relatively humid and the resurgence phenomenon is more serious. Especially in the rainy season in the south, the humidity will be more serious and there will be more mosquitoes, which is not suitable for rheumatism patients to live in.
For buildings with a height of less than 30 meters (about ten stories), channel steel floors are usually located in the basement or the top floor and roof; When a building (high-rise) has many floors, the channel steel floor is usually located in the middle of the building.

Channel steel is a kind of section steel, as the name implies, it is a kind of channel steel. Generally used for columns, beams and ladders of steel structures, foundation embedded parts are generally made in electrical engineering, which is called foundation channel steel. Because of its special shape and bearing capacity, it is also widely used in the support structure. Channel steel belongs to carbon structural steel used in construction and machinery, and it is a complex channel-shaped steel. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. It requires good welding and riveting performance and comprehensive mechanical properties in use.
Additional: Why does the building have channel steel floor?
Because channel steel can bear a certain load, it can be used to share the weight of the whole building, thus playing a supporting and bearing role. So when we were in Gai Lou, we used channel steel in every building. But the disadvantage of channel steel is that as long as someone often walks on it, it will make some noise. Therefore, the floor built with channel steel is generally used to place installation equipment and cannot be occupied by people, so this floor is also called channel steel floor.
