1. 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. You can consult the sales department of the developer when buying a house. General high-rise residential buildings 10-20 floors will be equipped with channel steel floors. The height of channel steel is generally 2.2 meters, and the specific floor is 10 to 20 floors. The lowest layer is channel steel layer.
2, because the construction equipment in operation will produce sound, vibration, radiation, etc. If the sound insulation and shock absorption measures are not good, the room near the channel steel floor is easily affected by noise and vibration. So when buying a house, try to avoid the channel steel layer.
Extended data:
1, channel steel is divided into ordinary channel steel and light channel steel. The specification of hot rolled common channel steel is 5-40 #. The specification of hot-rolled flexible channel steel supplied by both parties is 6.5-30 #. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed cabinets. Channel steel is often used with I-beams.
2. Channel steel can be divided into four types according to its shape: cold-formed equilateral channel steel, cold-formed unequal channel steel, cold-formed internal rolled channel steel and cold-formed external rolled channel steel.
3. According to the theory of steel structure, it should be the flange of channel steel, that is to say, channel steel should be standing, not lying.
