Some friends want to know how many layers the channel steel layer is, and some say that the 3rd layer, 6th layer, 8th layer, and 12th layer are not necessarily correct. To know this problem, we must first understand that it is the channel steel layer.
The channel steel layer refers to the floor where many holes will be punched in the floor and floor during the construction of the main structure of the high-rise house, which is used to erect cantilevered scaffolding and use the bottom support beam to rest the floor. After the channel steel layer is removed after construction, many holes will be left in the walls and floors of the layer, and these holes will be repaired by workers.
First, only the height of the floor more than 11 layers will appear channel steel layer, because the low layer does not need to fix the cantilevered scaffolding, and the channel steel layer and the channel steel layer can not exceed 20 meters, according to each layer of 3 meters to calculate, there will be a channel steel layer at intervals of 6 layers, and the total height of the 6 layers is 18 meters less than 20 meters, which is in line with the requirements of the building.
Second, if the first floor is a normal floor height, the channel steel layer will generally be built from the 4th floor, and the channel steel layer is 4 layers, 10 layers, 16 floors, and so on.
Third, if the first floor is a shop, the channel steel layer will generally be built from the third floor, and the channel steel layer will be 9 floors, 15 floors, and so on.
The only thing that can happen to the channel layer is the problem of water leakage, because the exterior wall has been damaged and replaced. However, the workers should do a good job of filling at the end of the work, and after filling, they should also do the insulation layer, waterproof layer, and exterior wall material. Generally speaking, there will be no problems, and even the probability of leakage will be lower than that of windows, so you don't have to worry too much, if you really care, confirm with the sales before buying a house. If you're not sure, go straight to the construction site.
1. The top floor, the top floor is cold in winter and hot in summer, and there is a risk of water leakage, in addition, the elevator machine room is generally built on the top floor, and the operating noise may be a bit loud. If there is an attic outside the column.
There is a risk of backflow on the 2nd and 2nd floors, and if the sewer pipes of the entire building are blocked, there may be a problem of sewage backflow. This is because the sewage cannot be discharged smoothly and the pressure will cause the sewage to flow back out from the lower outlet (e.g. toilet, floor drain, etc.). Of course, if it is made of independent sewers, you can consider it.
Building, there is nothing wrong with these floors themselves, don't think about it if someone in the family cares.
5. The waistline layer, the waistline layer has the risk of water accumulation, which may penetrate into the wall of the home, resulting in mold on the wall.
6. There is no problem with the channel steel layer, but spending the same amount of money to buy a tinkered house may be a little difficult in my heart, and I don't want to consider it.
