What should be the distance between the first main keel of the light steel keel ceiling and the wall

The distance between the first main keel of the light steel keel ceiling and the wall is 30 cm.

If the fixed point of the beam and pipeline is greater than the design and regulation requirements, the length of the boom is equal to 10OOmm, the fixed point of the boom should be increased, and the fixed point spacing of the finished screw welding w boom can also be bought 900 10OOmm, the boom of 8 should be used, if it is greater than 10OOmm, if it is greater than 10OOmm, the length of the boom is less than 10OOmm.

w does not go to the ceiling, should adopt the boom of 10, the other end can be used to tap out the screw rod greater than 1OOmm, one end of the boom is welded with the L30X30X3 angle code (the aperture of the corner code should be determined according to the diameter of the boom and the expansion bolt), also should be provided with reverse support, the boom of 8 can be used. The ceiling of the person on W can adopt 6 booms.

Precautions for suspended ceilings:

1. First prepare for the installation of the ceiling First check the flatness of the surface of the ceiling to ensure that there are no cracks on the ceiling surface, and then design the style and shape of the ceiling to plan for the subsequent installation.

2. Determine the material selection of the living room decoration ceiling and use non-combustible or flame-retardant materials to improve safety performance.

3. The ceiling style should be matched with the living room The two styles do not match, and it will be uncoordinated.

4. The color selection of the ceiling should be lighter than the surrounding walls.

The distance between the first main keel of the light steel keel ceiling and the wall is 30 cm.

Light steel keel ceiling is standardized, the spacing between the main keel and the main keel can not exceed, if it exceeds this distance, you should try to do reinforcement treatment, the spacing between the auxiliary keel and the auxiliary keel is 30cm, and the thickness of the gypsum board is.

If the thickness of the plasterboard is 12mm, the spacing between the auxiliary keels can be enlarged to 40cm. However, in the actual construction, the spacing of the auxiliary keel is 30cm, and basically no one makes it 40cm.

The distance between the first main keel of the light steel keel ceiling and the wall is 30 cm.

Expansion bolts are used to fix the hanging rods. Not on the ceiling, the length of the boom is less than 1000mm, the boom of 6 can be used, if the size of 1000mm, the boom of 8 should be used, and the reverse support should also be set.

The boom can be made of cold-drawn steel bars and disc round bars, but the use of disc round steel bars should be mechanically straightened. The ceiling of the upper person, the length of the boom is less than 1000mm, the boom of 8 can be used, if it is greater than 1000mm, the boom of household 10 should be used, and the reverse support should also be set.

Light steel keel ceiling construction method.

1. Spring line. First of all, use the level to find out the horizontal points of each corner of the living room, mark them with pink lines, and then connect the horizontal points with ink lines, and pop up horizontal lines on the wall. Note that in general, the distance between the horizontal line and the ground should be more than 500mm.

2. Fix the hanging rods.

After the elastic line is completed, the position of the main keel should be found according to the design plan, and the distance of about 1000mm on both sides of the main keel should be extended as the center of the main keel as the fixed point of the hanging rod.

3. Install the side keel.

Before the installation of the side keel, it is necessary to play the line and determine the position of the side keel. However, during operation, it is necessary to first fix the L-shaped light steel keel on the embedded wooden bricks with self-tapping screws along the keel line.

4. Install the main keel.

The main keel is hung on the boom, and the length of the room is between 900-1000mm. In addition, the cantilever section of the main keel can not be greater than 300mm, otherwise a boom should be added.

5. Install secondary keel and gypsum decorative boards.

When installing the secondary keel, it is necessary to maintain a distance of 300 -600mm from the main keel, and fix the secondary keel on the main keel with a T-shaped galvanized iron sheet, and the two ends of the secondary keel should be placed on the horizontal flange of the L-shaped side keel. Then correct the keel skeleton, and then decorate the surface with gypsum board.

According to the overall length of the overall top surface to calculate, the main keel spacing should not be greater than 800mm, and then evenly distributed, if the wall is less than 800mm, do not add the main keel, if greater than 800mm (such as 900mm or 1100mm), add another one accordingly (at this time the main keel is 100mm or 300mm).

Thirty centimeters, which is the distance required for the specification.

The distance between the first main keel of the light steel keel ceiling and the wall is 30 cm.

According to the overall length of the overall top surface to calculate, the main keel spacing should not be greater than 800mm, evenly distributed, if the distance from the wall is less than 800mm, do not add the main keel, if greater than 800mm, add another one accordingly. The fixed point spacing of the wboom is 900 10OOmm, if the fixed point of the beam and pipeline is greater than the requirements of the design and regulations, the fixed point of the boom should be increased. w does not go to the ceiling of people, the length of the boom is less than 10OOmm, the boom of 6 can be adopted, if it is greater than 10OOmm, the boom of 8 should be used, and the reverse support should also be set.

w on the ceiling, boom length is equal to 10OOmm, can use 8 boom, if greater than 10OOmm, should use 10 boom, one end of boom with L30X30X3 angle code welding (corner code aperture should be determined according to the diameter of boom and expansion bolt), the other end can be used to tap out of the screw rod greater than 1OOmm, can also buy finished screw welding.

The fixed point spacing of the wboom is 900 10OOmm, if the fixed point of the beam and pipeline is greater than the requirements of the design and regulations, the fixed point of the boom should be increased. w does not go to the ceiling of people, the length of the boom is less than 10OOmm, the boom of 6 can be adopted, if it is greater than 10OOmm, the boom of 8 should be used, and the reverse support should also be set. w on the ceiling, boom length is equal to 10OOmm, can use 8 boom, if greater than 10OOmm, should use 10 boom, one end of boom with L30X30X3 angle code welding (corner code aperture should be determined according to the diameter of boom and expansion bolt), the other end can be used to tap out of the screw rod greater than 1OOmm, can also buy finished screw welding.

JGJ345-2014 Technical specification for ceiling engineering in public buildings.

Under normal circumstances, about 30cm is fine.
