Gypsum board ceiling arc, gypsum board arc tutorial

Plasterboard for the lower part of the ceiling, yes. The edge of the arc is generally made of wood or woodworking board, the arc is larger and can be edged with gypsum board, and the edge is sealed with plywood if the arc is small, and two to three layers are made, and white glue is used between the board and the board, pay attention to the staggered seams.

Gypsum board, the curved position is made of Osson board.

The arc edge of gypsum board is not gypsum board, gyplight board cannot be bent, and it is made of wooden boards.

The overall arc of the ceiling is directly cut from gypsum board.

Small wooden squares are embedded on the keel of the gypsum ceiling.

On the edge of the ceiling, it is to take a relatively thin nine-centimeter board, woodworking board and other boards and nail the wood square.

Forms the preliminary shape of the arc edge.

Then the joints of the wooden board and the gypsum board are pasted with kraft paper or cloth strips, and then filled with putty to prevent cracking at the junction of the two materials, which affects the use and appearance of the ceiling.

The outer layer is carefully made into a perfect arc with putty.

Then the whole is sanded to make the surface smooth and smooth.

Finally, according to the process of latex paint, the primer and topcoat are painted.

Gypsum board pasted with a wooden frame to make a keel in the addition of a circle of spotlights is now popular this see the light does not see the light can find a decoration shop . It's better to have a personality.

Of course, it's made of gypsum board, and if you ask a carpenter to do it, you say you're going to make an arc, and you find some ** to show him, or draw a sketch, and they can make it.

Hello dear! Glad for your question! Gypsum board to do arc tutorial:

The construction method of gypsum board arc (divided into two types): use blockboard to make the arc first, and connect the formed joinery oak seepage with keel (wood keel and light steel keel) at the appropriate position, and then attach the gypsum board to the blockboard and keel. Make an arc, depending on how big your arc is.

If it is a micro-arc wall, the gypsum board can be fixed directly on the keel, and the deflection of the board itself is enough to bend the arc. The deflection of the plate is not enough for the curvature you need, and the V-shaped groove (longitudinal) is cut out on the back with a utility knife and then fixed. The above method can not achieve the curvature you require, only cut the gypsum board into slender strips, leave the seam fixed, and then use gypsum caulking to repair and polish into an arc, which is common in the practice of wrapping cylinders.

In addition: gypsum products should not be exposed to water, it is said that the pure spray of blisters is slippery, and even the composition of gypsum does not know the beam ridge. The strength of gypsum in contact with water is greatly reduced!

Large arcs can be made directly, and small arcs should be spliced with small pieces and leveled with plaster.

On the back of the drywall, use a utility knife to cut the paper on the surface of the drywall, and you're good to go.

It can be bent into an arc directly.

If it's flat, draw it and cut it with a knife.

First, use the woodboard to make a shape according to the arc (for keel), and then fix the gypsum board on the woodworking board. As shown below:

You can use the gypsum board of the brand "Knauf" in the market (, at present, the board in the mainland market can be arc-shaped, but **generally more expensive, different regions** is not the same, the ex-factory price is about 22-23, plus the freight and merchant interests to sell to about 28.

Shengkan modular custom gypsum board ceiling, customized production by manufacturers, on-site installation by workers, will not produce construction waste, saving material and labor costs. It only takes 2 days to install the production belt, which can be done without cracking, and all kinds of heterosexual complex gypsum board can be easily completed.

If the garden is big, use the carpentry board to lower it first. The base is not strong with a keelSleeping garden with Australian version or gypsum board can be happy every day satisfaction.

Now put the gypsum board on the platform board, nail one end of a wooden strip to the platform board, turn the wooden strip in half and a circle, and draw it on the plasterboard to cut it completely, and the dome is half a top....

1. According to the design of the ceiling height on the wall, its level allowable deviation is 5.

2. Boom installation.

1) Selection of booms. Generally speaking, the selection of booms for light steel keel ceilings can be based on the standard. Figure, the diameter of the light steel ceiling is 6, and the diameter of the medium and heavy is 8. If the design has special requirements and the load is large, it needs to be determined by structural design and design.

2) According to the design or standard? Figure to determine the hanging point spacing. Generally, the ceiling spacing is 1200 1500, the ceiling spacing of the upper person is 900 1200?.

3) Fixation of the ceiling. For the cast-in-place concrete roof, the boom or embedded iron parts can be embedded during the construction of the structure, so that the boom and the iron parts are welded. In old buildings or under the concrete round hole slab, you can use a nail gun to fix the hanging point iron (small angle iron), and a spacer needs to be added when shooting nails.

The nail must be firm (if there is a hole in the tail of the nail, the boom can be fixed with the eyelet of the nail as the case may be, and the iron part can be saved). Or expand the bolt under the lifting point position.

4) When the boom is installed, the upper end should be welded firmly with the embedded parts, and the lower end should be threaded, equipped with a nut, and the end thread should be exposed not less than 3mm.

3. Keel installation.

1) The large keel can be welded with the boom by welding method. But it is best to connect with the boom with a boom piece and tighten the screws to clamp firmly. The large keel can be extended with connectors. After installation, it is necessary to carry out leveling, considering the arching height of the ceiling, not less than 1 200 of the short span of the room.

2) The middle keel is fixed with a hanger and a large keel. The spacing between the keels depends on the size of the plate. When the spacing is greater than 800?

When the middle keel should be increased between the small keel, which should be parallel to the middle keel, and fixed with the hanging piece and the large keel, its lower surface is on the same level as the middle keel.

3) The middle and small keels of the cross brace should be installed at the joints of the plate seams, and the cross brace keel should be fixed with plane connectors and small and medium keels.

4) Finally, install the special-shaped roof or curtain box special-shaped keel or teach aluminum keel.

4. Paper-faced gypsum board and other boards are fixed.

1) To fix the gypsum board, you can fix it with the keel directly with a self-tapping screw gun with self-tapping screws. The nail head should be embedded in the board surface. Nail head coating anti? After painting, use putty to level, and use 5*25 or 5*35 cross-countersunk self-tapping screws for self-tapping screws.

Gypsum board seam treatment, if it is a tight seam, the gypsum board should be left 3?Board seams, putty, fiberglass seam tape. Then scrape smoothly with putty.

If you need to leave a seam, it is generally 10?In this seam, the color paste can be brushed according to the design requirements, and the concave aluminum strip can also be used to press the seam.

2) When fixing decorative gypsum board and other material boards, the board should be in place first, and the plate and keel should be drilled through with an electric drill (the diameter of the drill bit is slightly smaller than the diameter of the self-tapping screw), and the self-tapping screws should be fixed. The spacing of the self-tapping screws is not more than 200?.
