The structural level of light steel keel ceiling and its practice

First find the pure grip level of the ceiling, and then install the expansion screws on the roof. Under the boom, the distance of the boom should not exceed 80mm to install the hook, and then on the 38 keel in the use of the hanging installation of the auxiliary keel to do Huai, we generally do all Pisan is a 40mm square, the specification of the gypsum board is 120mm 3000mm. Drywall installation to leave a gap of 5mm.

Then there is the adhesive powder to fill the leveling. Then glue the bandage, scrape the putty, brush the paint.

Very professional, briefly talk about the method: 1. Punch holes on the original top surface and fix it with expansion screws and wire rods. 2. The upper beam Hu sues the slag and does not have a dragon leveling 3, and connects the auxiliary dragon leveling on the main socks Nalong 4, and fixes the gypsum board with self-tapping screws.

Construction technology Construction sequence: elastic hanging point position line elastic ceiling height line drilling installation boom installation main keel installation T-shaped main keel and small bone mechanical and electrical equipment installation, acceptance installation gypsum board 1, according to the room 50 horizontal line, with a ruler vertical vector to read the hall to the ceiling design elevation, office line back, horizontal allowable deviation 3), corridor line back along the wall around the ceiling elevation line, and on the wall to draw a keel binning line, boom from the wall 150mm, the main keel from both ends of the wall distance is not more than 150mm, And the spacing of each keel is 1m, and the 1m 1m square line is bounced under the floor slab. The ceiling of the open large office is arched 20mm, and the small Fuzhao office is arched 5mm

The corridor and arch are 2mm, and the short span of the room is arched. 2, after the elevation line of the roof and the position of the keel binning line, determine the elevation of the lower end of the boom, according to the position of the large keel and the distance between the boom, the boom without screws one end and 40 40 4 corner yard welding, the boom such as the rod with 8 expansion bolts and the ceiling fixed. 3. The exposed length of the thread at the end of the boom should not be less than 3mm, and when installing the large keel, the large keel should be connected to the boom with a hanging piece, and the screws should be tightened.

The large keel extension can be connected with a plug body. After the installation of the large keel should be leveled and 50 main keel should be arranged parallel to the direction of the lamp, and the boom should avoid the position of the tuyere and the lamp. The open office ceiling needs to be welded 12 meters on the upper part of the large keel to strengthen the lateral stability of the large keel and the integrity of the boom.

5. After the installation of the keel is completed, after checking the elevation, spacing, straightness and hanging load to meet the design requirements, the installation of the roof starts from one end of the keel in the middle row of the roof, first installs a small keel with a side card file, and then puts the calcium silicate plate on the flange of the keel on three sides, and then installs the small keel on the other side, installs it in branches according to the above procedures, and finally adjusts the T-shaped keel by pulling the line. Wait for water, electricity, air conditioning and other professional processes to be completed before installing the ceiling. 6. When the gypsum calcium silicate board needs to be cut at the lamp mouth, tuyere and wall edge, it should be cut neatly perpendicular to the ribs on the back of the board.

The lamps and tuyeres should be adjusted so that the board is on the same level all around. Non-monolithic boards can be slotted with planers to lower the cut side to keep it level, and the nail holes must be treated with anti-rust treatment (anti-rust paint) after the installation of the plasterboard in the corridor.

Find the horizontal line of the ceiling first, and then install expansion screws on the roof with a large eye. Under the boom, the distance of the boom should not exceed 80mm to install the hook, and then on the 38 keel in the use of the hanging installation of the auxiliary keel, we generally do 40mm squares, gypsum board specifications are 120mm 3000mm. Drywall installation to leave a gap of 5mm.

Then there is the adhesive powder to fill the leveling. Then glue the bandage, scrape the putty, brush the paint.

Very professional, briefly talk about the method: 1. Punch holes on the original top surface and fix it with expansion screws and wire rods. 2. The upper main dragon is leveled, 3. The secondary dragon is connected to the main dragon, and 4 is leveled, and the gypsum board is fixed with self-tapping screws.

1. The selected light steel keel should meet the design requirements and ensure the quality.

2. All spare parts and keels in the ceiling should be galvanized.

3. The keel, boom and connector should be in the correct position, the material should be smooth, straight, firmly connected, and not loose.

4. Where there is a suspended load-bearing part, the transverse secondary keel must be added.

5. The boom shall not exceed 300mm from the end of the main keel.

6. The allowable deviation standard of quality can refer to the wooden ceiling. How to check the decoration quality of aluminum alloy keel ceiling, you can also refer to the light steel keel ceiling.

Light steel keel is a new type of material often selected for modern home decoration. It is a ceiling and skeleton supporting material made of galvanized steel plate, cold bending or stamping, which has the characteristics of light weight, high rigidity, good fire and seismic performance, and convenient processing and installation. The light steel keel skeleton is divided into U-shaped keel and T-shaped keel according to the material section.

When choosing, pay attention to the thickness of the keel, preferably not less than millimeters.

The construction steps of the light steel keel gypsum board ceiling mainly include: elastic line, installation of large keel boom, installation of large keel, installation of medium keel, installation of small keel, installation of cover cotton board, installation of pressing strip, brush anti-rust paint, etc.

1. Install the boom.

When the floor slab is prefabricated slab, the reinforcement hook of suspension boom has been embedded in the slab joint, only the upper end of the boom can be bent and twisted firmly through the hook hole.

When the floor slab is cast-in-place slab, the position line of the embedded part should be released at the bottom of the floor slab first, the embedded part is nailed to the bottom of the floor slab with a nail, and the upper end of the boom passes through the hanging ring hole on the embedded part and bends and twists firmly.

2 large keels.

The large keel vertical hanging piece is set on the large keel as a number, the large keel is handed up, the lower end of the boom is penetrated into the upper hole of the large keel vertical hanging piece, and the nut is initially screwed.

According to the height of the cusp of the ceiling in the room (generally take the short span of the room), calculate the arching value at each hanging point of the large keel, twist the nut to make the large keel adjust the arching value, after the adjustment, the vertical hanging piece of the large keel is fastened.

3. Install the keel.

Put the middle keel vertical hanging piece on the large keel as the number, hand the middle keel up, make the middle keel buckle the middle keel vertical hanging piece. If the middle keel intersects with the cross strut, then place the middle keel plane connector on the middle keel, and the cross brace buckles the middle keel plane connector.

4 small keels.

Put the small keel vertical hanging piece on the large keel, hand the small keel up, and make the small keel buckle the small keel vertical hanging piece. If the small keel intersects with the cross brace, the small keel plane connector is placed on the small keel, and the cross brace buckles the small keel plane connector.

5. Cover the panel.

After the keel is installed and checked to be correct, the cover panel can be installed, and it can be fixed with self-tapping screws or adhesive according to the cover panel material (see various cover panel installation methods for details).
