How to lift the ceiling on the top floor of the light steel villa, and what materials are used for t

1. Leveling line. 2. Top punching. 3. Hanging strip on the top. 5. Hang the middle boom. 6. Forming.

Find a professional master, don't fool around. Are you the head of the household or the contractor? Do you want to ask what kind of shape to make or how? The problem is too. If you ask about the construction steps, the first floor is very correct.

Clause. First, the installation of the ceiling pre-construction preparation.

Before the construction of the ceiling, it is necessary to check whether the structural dimensions are consistent with the preparatory design drawings; Whether the equipment pipeline is installed clearly; Whether the ceiling installation materials and tools are complete.

Clause. Second, smallpox base treatment.

Before installing the ceiling, the ceiling should be inspected and remedial measures should be taken immediately if the quality does not meet the construction requirements.

Clause. Third, the ceiling elastic line positioning.

There are two kinds of ceiling elevation lines and keels respectively. The elevation line can mark the position of the ceiling plane with the water column method, and the elevation line can be popped up according to the position; The positioning of the keel should be arranged according to the size of the veneer and the position of the keel. In order to make installation easier, it is recommended that the centerline spacing should be about two millimeters in the size of the veneer.

When you are arranging the keel grid, try to ensure the uniformity and integrity of the keel grid, so that the ceiling has a more regular decorative effect in the later stage. First of all, draw the ceiling area in the drawing according to the proportion, and then arrange the ceiling keel on the paper according to the principle of keel arrangement. Once you have determined the location, position it on the wall.

Clause. Fourth, fix the boom.

The hanging piece is generally fixed with expansion screws or nails, and then the galvanized iron wire used to hang the keel is fixed on the hanging piece through the hole in the angle steel block. The suspension is recommended to be made of telescopic boom material. The types of telescopic booms are more diversified, and the more common ones are straightened with No. 8 lead wires, and the two lead wires are connected with a spring steel sheet with holes, and the spring steel sheet is mainly adjusted and fixed.

Clause. Fifth, install the keel.

The keel is divided into primary and secondary keels. Keel spacing can be measured with a die gauge. First of all, the main keel is hoisted, and then a temporary fix is made at a position higher than the elevation line, if the ceiling area is slightly larger, it is recommended to hoist several parts.

Then install the secondary keel between the main keel, which is often referred to as the cross-brace keel. The length is then measured using a die gauge and the installation is complete.

Summary. The main reasons for the cracking of the putty are as follows: 1: The moisture content of the ceiling exceeds the normal value (the normal value is less than 7%), and the wooden keel is deformed due to the drying fission process, which makes the gypsum board crack 2:

The screws between the light steel keel bars and the hanging are not fastened, resulting in the overall loosening of the keel frame, due to the convection of the air in the cavity of the keel ceiling and the air below the ceiling, the gypsum board vibrates up and down and cracks 3: there is a problem with the splicing of gypsum board, when the corner appears, the gypsum board is cut into the "L" shape, do not cut the "one" shape. 4：

Gypsum board quality problems, good gypsum board is lighter, the substrate has built-in fiber reinforcing wire, gypsum board veneer kraft paper is smooth and capricious, etc., if the inferior gypsum board is used The strength is reduced, the flexibility is poor, and cracks are inevitable.

What materials are used for light steel villa ceilings; The material of light steel keel ceiling is generally the most suitable for gypsum board, which can start the fire prevention effect.

The light steel keel sling wire is generally fixed with a nail gun or expansion screw. Light steel keel ceiling construction method 1, need to prepare the material of the light steel keel ceiling construction process: light steel skeleton, pendant, connector, hanging plug-in, boom, nail, self-tapping screw, cover panel, adhesive.

2. The steps are the first to quietly grasp the elevation line of the ceiling, and then according to the surrounding walls of each floor, the horizontal control line is played, and the construction process of the light steel keel ceiling requires the line to be clear and accurate.

However, the worker said that there was a vibration on the second floor, which would cause the plasterboard putty to crack.

The main reasons for the cracking of the putty will be as follows: 1: The moisture content of the ceiling exceeds the normal value (the normal value is less than 7%), and the wooden keel is deformed due to the drying fission process, so that the gypsum board cracks 2: The screw between the light steel keel module suspension bar and the hanging is not fastened, resulting in the overall loosening of the keel frame, due to the convection of the air in the cavity of the keel ceiling and the air below the ceiling, the gypsum board vibrates up and down and cracks 3:

There is a problem with gypsum board splicing, and when there is a corner, the gypsum board is cut into an "L" shape, and do not cut the "one" shape. 4: Gypsum board is the first quality problem, good gypsum board is lighter, the substrate has built-in fiber reinforcing wire, gypsum board veneer kraft paper is smooth and capricious, etc., if the inferior gypsum board is used The strength is reduced, the flexibility is poor, and cracks are inevitable.

The worker said that the upstairs vibration will cause the putty to crack, and it is not recommended to do it.

Dear, I can't see the real thing here, but I can only give you a little advice, it's better for you to listen to the suggestions of the workers.
