Anonymous users2024-01-22The bottom of the suspension bar will be connected to the main keel with a large crane, and the bottom of the main keel is connected with the auxiliary keel, and there are expansion screws fixed with the top surface of the building, so it is necessary to enter the top surface of the building at least 4 cm, and the length of the large crane is subtracted below - generally about 13 cm (this specification is different), and the thickness of the auxiliary keel is negligible. If the distance between the top elevation and the top surface of the original building is 1 meter, then the length of the suspension bar is: 100-13 + 4 = 91 cm, of which about 3 cm will be in the ceiling, which is used for the margin of the sleeve nut.
In fact, you can connect the large hanger and expansion screws with the hanging bars, and then measure them to know.

Anonymous users2024-01-20Hello! The suspension bar will be connected to the main keel with a large crane with a leakage, and the main keel will be connected with the auxiliary keel below, and there are expansion screws on the top surface of the building to enter the top surface of the building at least 4 cm, as long as the length of the large crane is subtracted - about 13 cm (the same specifications) The thickness of the auxiliary keel ignores the false top elevation, the distance between the top surface of the original building is 1 meter, the length of the suspension bar: 100-13 + 4 = 91 cm, which will have about 3 cm or so in the ceiling for the sleeve nut margin, in fact, the large hanging, The expansion screw is connected with the hanging bar, and the amount of skillful search under the mold is known.

Anonymous users2024-01-19The main keel will be connected with a large crane below the main keel, and the main keel will be connected with the auxiliary keel below, and there are expansion screws fixed on the top surface of the building, and the top surface of the building should be fixed to enter the top surface of the building at least 4 cm, as long as the length of the large hanging is subtracted - about 13 cm (the same specifications), the thickness of the auxiliary keel is ignored, the distance between the top surface of the original building is 1 meter, and the length of the suspension bar: 100-13 + 4 = 91 cm, which will have about 3 cm or so in the ceiling for the rest of the nut.
In fact, the large hanging, expansion screws and hanging bars are connected to know the measure.
The cost price in Xi'an is 50 yuan square meters, excluding the price of scraping putty and brushing latex paint.
The spacing of the main keel is usually 900 1200, the secondary keel covered keel is 400 * 400, or 400 * 600, the side keel is the perimeter of the wall, the grille lamp and the maintenance port and the air conditioning Wang tuyere will have the keel strengthened, the ordinary decoration gypsum board with a single layer, the fine decoration gypsum board low with a double layer, the early high level with a single layer of 12 thick Lu Lingqin, there is a modeling ceiling, the amount of gypsum board is calculated plus loss.
The following is the general process, and the specific process suggestions still need to go to the construction site to see it. >>>More
The light steel keel gypsum board ceiling can not be seen after installation, so it belongs to the dark keel ceiling. >>>More
Judging from the situation you said above, you don't seem to know about the project, the light steel keel is the material that plays a tensile role inside, and the gypsum board is sealed on the light steel keel, why there are two ceilings. The ceiling is only divided into two kinds, one is the bright keel ceiling and the other is the dark keel ceiling, the bright keel is sealed with silicon cover plate (a piece is connected to the kind), and the dark keel is completely closed with gypsum board. The wooden keel is the same thing as the light steel keel, that is, the base layer is made of different materials. >>>More
