1. What floor is better for high-rise buildings?
When choosing a high-rise building, because the total number of floors is different, the floor selection is also different. Generally speaking, the rules for selecting floors for high-rise residential buildings are: the total number of floors is more than 1/3 and less than 2/3. In view of the fact that there are old people in the home and sewage pipes appear in the middle floor, the following are the better floors of some high-rise residential buildings:
1, total height 15 floors: the better floors are 5-7 floors.
2. Residential buildings with a total height of 18 floors: 6-7 floors are preferred.
For a 3.24-story house, the total height: the better floors are floors 6-8, 15-20.
4. The 28-storey residence with total floor height: the better floors are 6- 10 and 15-22.
5.30-story residence, with total height: the better floors are 6- 10 and 15-24.
It is a principle to buy a house according to your own needs. The higher the floor, the better. If there are elderly people or people with mobility difficulties at home, it is best to choose low-rise or residential buildings with elevators.
What are the advantages and disadvantages of high-rise buildings?
1, advantages of high-rise buildings
(1) Good scenery
As the saying goes, if you stand high, you can see the scenery that others can't see if you live high. Imagine, on a beautiful morning, opening the window, warm sunshine will shine in, which can increase comfort.
(2) Low noise pollution
According to the research of China Urban Environmental Pollution Control Technology Research Center, with the increase of distance, the noise will decrease, and the noise will decrease by about 1 0 dB per floor. However, this also needs to be discussed on a case-by-case basis. If the residential area is close to the main road of the city, the noise on the third to fifth floors is often the loudest, but the noise above the eighth floor will be relatively small.
(3) Relatively healthy
High floors are not easily blocked by obstacles, with good lighting and adequate ventilation. The room is brighter and quieter, and people will be more relaxed. Moreover, the humidity of high-rise residential buildings is low, and the chances of suffering from diseases such as osteoarthritis and rheumatism are relatively small.
2. Shortcomings of high-rise buildings
(1) easy to fall.
Regarding the railing height of high-rise corridors, General Principles for Design of Civil Buildings (GB50352-2005) stipulates that when the height of the airport is 24m or above, the railing height should not be less than 1. 10m.
But for high-rise residents with children, they are still worried, because if the railing height is not enough, the risk of children falling will increase. Therefore, if you live in a high-rise building and have children, you must not leave them alone at home.
(2) There are hidden dangers in fire safety.
At present, the fire ladder truck can only reach the 28th to 30th floors at most. If there is an accident such as a fire among the residents above the 30th floor, it is likely that the rescue will be much more difficult because the floor is too high.
(3) Waiting for the elevator for a long time
High-rise residents often wait longer for the elevator than low-rise users, which invisibly increases the time cost of residents. The higher the floor, the bigger the pool will be. In addition, high-rise residents are most afraid of power outages. Daily travel depends on the elevator, and the elevator runs normally. Once the power goes out, the high-rise residents will be very miserable.
(4) Reduced usable area
In order to enhance the bearing capacity of low-rise buildings, builders often increase the thickness of shear walls. The thickness of shear wall will increase with the increase of floors, so the relative practical area will decrease.
(5) It is easy to cause physical discomfort
If you are a house buyer with acrophobia, it is better to choose a low-rise house. Otherwise, standing on the windowsill and looking out every day will make you dizzy and affect your mood.
