2. The storey height refers to the residential height measured by "storey". The height of each floor is required by the state in design, and this height is called the height of the floor. It usually includes the distance from the lower floor or floor to the upper floor.
3. After the building is completed, the structural layers of each floor of the building have been buried by the upper structural layer, so it is very difficult to carry out actual measurement and subsequent retest or detection; In addition, the structural plane is a rough and uneven surface, which can not be measured more accurately. Therefore, although it is scientific and feasible to take the structural layer of the house as the datum for measurement, it is difficult and not suitable for more precise measurement, so it is rarely used for real estate measurement.
4, some buildings can't measure the height, such as the basement entrance, caves and other buildings can't measure the height. In order to ensure people's basic activity space, the height of building space should be replaced by the clear height standard, which has reached the understanding that the national clear height standard should also be unified.
5. In addition to "meter", the height measurement of residential buildings can also be calculated by "building". The height of each floor has certain requirements in design, which is called the height of the floor. The story height usually refers to the distance between the lower floor or the floor to the upper floor. The difference between the height of the floor and the thickness of the floor is called the clear height. In order to reduce costs, save building materials, save land and other considerations, the height of residential buildings is generally about 2.8 meters.
