How to make a hanging gypsum board dome with reflective cao? Thank you

The friend's question is, first of all, to achieve the practice of the dome:

1. The shape and size of the dome should be determined according to the size of the space and the design requirements.

2. Draw an arc on the ground according to the design drawings (that is, lofting on the ground).

8 thick steel bars are used for the dome below the meter, and 10 thick steel bars are used for the dome below 3 meters, and the larger the roof, the thicker the steel bar. According to the arc of the ground, the steel bar is bent to make radial bars, and the material is cut according to the spacing of 300, such as 32 radial bars for a dome with a diameter of 3 meters. The radial reinforcement is fixed to the square roof or structural beam, and the weft reinforcement is made according to the radial reinforcement.

The position where the radial and weft ribs intersect is tied with a binding wire, and then the radial ribs and weft ribs are tied to the radial ribs with a screen with an eye distance of 10. Survive like a bird's cage.

4. Mix the cement ash with a hemp knife, lay the base, and wait for the hardness (note that it is not completely dry). Plaster the lid of the bag with 1:1 sand plaster into a living thickness of 30 40. Make a scraper according to the curvature of the designed living radius, put it on it to scrape, and it is a very round dome.

As for the reflector you are talking about, with the dome reflector is not a problem. I am an expert in domes, doing all kinds of domes, and there are steel structure dome projects to find me. I hope you are satisfied with my answer, give me extra points.

First, according to the design size of the line, then according to the positioning of the line to hang the keel, according to the design of the reflector groove to lay the lighting line, and then install the gypsum board (the line light of the reflector groove is the last installation).

I use woodworking boards to make curved boards. It needs to be rounded, and then the woodworking board needs to be sawn piece by piece (the circle is made of woodworking boards) not the whole piece. The light steel keel needs to be fastened with long wooden screws.

The wooden keel is generally hit on the wooden keel with 50 straight nails. Usually we also use white latex trowel woodworking boards and then fix them. It is recommended that you find a decorator to do it.

1. Draw a circle on the woodworking board with nails and bai threads, and cut it with a handheld saw. (Or fix the hand saw on the inside of the wood, and according to the radius, fix the other end of the wood on the plank and cut it round.) In addition, according to the depth of the light trough, make a ring with the above method.

2. Cut the 3 centimeter board into long strips (or cut the strips with woodworking boards and then deviate from the strips laterally, with a spacing of 3-5 cm), and set the long strips on the side of the cut boards. Then the ring is fixed to the inside of the strip in the same way.

3. At the position of the ceiling, make more than 3 hanging bars outward in the center of the circle (see the size and weight of the circle), and the position of the hanging bars is slightly larger than the radius of the circle.

4. Fix the round side of the finished round on the hanging bar (the hook of the ceiling is the simplest), and then level and adjust the position.

5. Fix the auxiliary keel around the circle when the ceiling is suspended.

6. After the gypsum board is fixed first, it can be pulled off with a receipt according to the round edge.

Look at the size of the garden to be done, according to the size of the best stakeout on the top, and according to the material and modeling requirements to be staked. Just do it directly according to the material construction requirements.

1. Nail the foundation of the white wood strips, and then cut the gypsum board.

2. After nailing the wooden strips, use a knife to cut the inner layer of the leather paper on the back surface of the gypsum board, and then gently press and bend it to stick it on the round wood.

3. Then it is the laying of wires, which wraps the wires used by the light strip around the entire annular outer ring through the wooden frame.

4. Then measure the size of the empty part below, cut the gypsum board that is slightly smaller than this size, and fix it on the wooden frame with a code nail gun.

5. In the process of re-fixing, the position of the round hole should be roughly left, and then the final gypsum board sealing and fixing should be carried out.

6. Finally, use a knife to cut off the pre-measurement mark along the circular dimension, remove the redundant gypsum board, put it in a circle, and then use the fine gypsum board mixed with the hollow vertical baffle of the wooden circle, and the light strip is sealed and glanded.

What shape of the design of the bai-shaped ceiling should be determined according to your decoration style, so how to do the round ceiling, what are the steps to do the circular ceiling?

1. Material preparation: Prepare the necessary construction materials. According to the design drawings, determine the elevation, bounce the horizontal line, and prepare to start installing the keel.

2. Install stable brackets and keel frames: keels are the key to the stability of the ceiling. It is recommended to use a gypsum board ceiling keel of about 30*50mm to ensure the stability of the keel support.

Horizontal lines are projected at the edge of the wall; Cut the strips of wood to the desired length; Wooden strips with hammers and steel nails are fastened to the wall along the horizontal line; Then use a pneumatic code nail gun to fix it again. To install the wooden keel on the top surface, it is necessary to pay attention to the stability, so the expansion screws are used to fix the wooden strips.

3. Wooden ceiling combination installation: The circular ceiling frame is made of a combination of wooden keel and plywood. The plasticity of plywood can be used to make a circular shape.

Before the plate is installed, it must be glued and fixed to provide the stability of the ceiling. Generally speaking, the circular shape of the design drawings is made on the ground first, and then installed and fixed to the top surface. The curved corners of the ceiling can be sewn with 3mm plywood.

4. Ceiling sealing board: After installing the wooden ceiling frame, install gypsum board on the surface of the wooden frame.

Light steel keel is used in combination with wooden keel, blockboard substrate, gyppool finish.

It's a suspended ceiling, of course, it's cutting, and then stick a piece of gypsum board on the side and make it a circle with an air nail gun!

How is it round, is it an arc? Round also.

Wooden keel ceiling should be used, the shape is better than the wooden keel, and gypsum board is generally only used for light troughs and the like. Before doing it, soak the purchased wooden keel in water to bubble, and then you can shape it.

The European style is more beautiful, and then glued to the plaster line will be more beautiful.

This kind of dome has to be hung according to various factors.

1. Draw a scale drawing of the construction crane dome according to the proportion, and then the workers can construct according to the drawings.

2. Now there are circular ceilings that have been formed on the market, and its size, color, grade, etc. can be bought, and this operation avoids a greater degree of construction.

3. Find a decoration company directly and let a professional person do it.

Most of these sheds are made of gypsum board. Wooden squares can be used. Or MDF to make the shape you want. Then use facing drywall on it.

The first step is to draw a circle on the plasterboard according to the drawing;

The second step is to place the keel on top of the circle, and fix the keel with self-tapping nails or air nails;

The third step is to fix the fixed keel firmly with the original ceiling;

The fourth step is to fix the gypsum board to the keel; Fifth, if the sides of the circle need to be closed, use plywood with cut width. Completed.

Now there are molded round ceilings on the market, customized in size, different colors, quality and assurance, all using PU and resin high-temperature molding, low-carbon environmental protection and odor-free quality. There is no need to use gypsum powder to brush and coat, the powder will fall off after a long time, damaging the human respiratory system.

You have to first see how big the square meter of your ceiling is, remove it proportionally, you can draw a scale diagram with drawings, and then arrange the hole to make a boom, you have to arrange the seat of the dome, make the shape you want with the woodworking board, and then paste the gypsum board when the embryo is finished, screw it on, brush it with anti-rust paint bandage, scrape the putty, and finish it

It can be done with blockboard and multi-layer board.

1. According to the scheme of the design drawings, first determine the elevation and play the horizontal line;

2. Start to play keel, and the keel of the modeling ceiling is commonly used as a wooden keel. Now the most commonly used wooden keel in home decoration is 30 * 50 standard keel, according to the size of the ceiling, determine the position of the keel, generally spaced.

3. Then use the 5 centimeter splint to open the strip according to the actual size, fix the side and bottom, do a good job of sealing the bottom, or reserve the position of the lamp groove to seal the plate, and an elliptical base will be formed;

Paste the two yang corners (side bai) together, and the yin corners don't need to be pasted. With the zhi body operation dao method, with the construction of the ordinary yang angle.

The inner method is: Tolerance is the same. The key is that the speed should not be too fast, and it must be straight, otherwise the sunny corner will not be straight. The above answer is from the team "I know about decoration".

Caulk with caulk.

come, and then reinforce the seams with high self-reinforcing seam paper tape. The following is the information I have sorted out, you can refer to it: (1) Before construction, the surface treatment of the plate joints should be carried out to remove floating dust, loose matter and various substances that are not conducive to bonding.

The blended plaster caulking is then applied with a trowel to the joints of the wedge-shaped edges. Determine the position of the seam paper tape, and then use a trowel to glue the seam paper tape firmly at the upper end. (2) Then use a trowel to squeeze out the excess gypsum caulking paste from top to bottom, so that the paper tape is firmly glued to the gypsum board, and the center line of the paper tape is aligned with the board seam.

Use a trowel to apply the plaster caulking paste thinly to the surface of the seam paper tape, completely coating the seam paper tape. Use a batch knife to scrape off excess seam paste. After solidification, if necessary, it can be sanded and smoothed with fine sandpaper.

3) Use a trowel to apply a thin second layer of gypsum caulking paste, about 50 wide from the first layer on both sides, and then polish it with fine sandpaper after drying. (4) Apply plaster caulking evenly on both sides of the yin corner. Fold the seam paper tape in half and stick it into the corner so that it is tightly embedded in the plaster caulk.

The joints of the same plane are also squeezed out of excess caulking paste from top to bottom with a trowel.
