First of all, it introduces the method of yin-yang angle of wall surface.
1, the first batch of ash treatment
First batch of a layer of ash at the grass-roots level, and then play the line, so as to see the line clearly. Clean the corners of yin and yang and the surrounding pimples with a grey knife. If it is not cleaned up, the elastic line will hit an obstacle and will not bounce straight.
2, Yin and Yang Angle elastic line
At the vertical line of each Yin-Yang angle, a vertical line is dropped with a line to play the line. Based on the vertical line of Yin-Yang angle, a parallel line parallel to the vertical line of Yin-Yang angle is placed at 500mm on both sides, which is defined as "Yin-Yang angle standard line".
Before scraping putty on the wall, use plastering gypsum to level both sides of the angle of Yin and Yang within 500mm. The standard is to level vertically with 2m feet, and the detection error is less than 2mm. Angle of Yin and Yang to both sides 500mm away with plaster or putty to find shunping.
Step 3 brush putty
Straighten the corners along the chalk line with putty. When it's dry, open it with ash. Pull one end with 2m L aluminum alloy ruler, and push it from one side of the inner corner to the inner corner. When pushing into the corner, gently twitch back and forth and scrape out in parallel, so that there will be no small bend in the inner corner.
After being dried, check whether the angle of Yin and Yang is qualified, and check the wall smoothness at the angle of Yin and Yang according to the vertical line. If the error is within 5mm, it shall be leveled with the wall, and if the error exceeds 5mm, it must be leveled with gypsum.
4, Yang Angle bump prevention treatment
Because the outer corner protrudes, it is easy to be hit, causing damage to the wall or even people or furniture. In order to avoid this situation, anti-collision treatment can be carried out on the outer corner. The alternative is to smooth the outer corner and polish it into a small arc with sandpaper; Or you can install corner protectors.
Second, the wall Yin and Yang Angle line processing method
There are three decorative materials on the wall: paint, wallpaper and tiles. In the process of construction, we will encounter the problem of yin and yang angle of the wall. The following introduces the treatment method of yin-yang angle of wall surface.
1. Draw a corner in the direction of the line of Yin and Yang.
The yin and yang angles of wall paint must be straight. In order to ensure straightness, you must play the line when doing the internal angle. When snapping lines, visually find out the most protruding part of the wall, press these two points to pop up a black line, and then use 1.5-2 m angle aluminum model scratch line. The outer corner should be kept straight. Generally, 2-meter-long aluminum alloy should be used together when scraping, and the other side should be scraped with a scraper. In order to ensure the durability of the external angle, white cement and gypsum powder can be used when scraping.
2. The wallpaper is stuck in the corner.
When pasting wallpaper, the yin-yang angle of the wall is the most prone to problems. When pasting in the external corner, carefully paste the wallpaper on the wall with a scraper, cross the convex corner, smooth the wrinkles from top to bottom by hand, then cut the wallpaper along the vertical line with a utility knife, paste it with glue, and flatten it with a press wheel. When pasting in the internal corner, smooth the concave wall from the center of the last wallpaper, scrape the extended part up and down with a scraper and paste it on the wall, wipe the glue off the scraper and cover the wallpaper.
3. Tiles should be pasted on the corners of the wall.
When sticking tiles, the most difficult thing to deal with is the yin and yang angle of the wall. The more common way is to use tiles to splice themselves. The method is to often use a cutting machine or hand to pour tiles at a 45-degree angle, leaving more when pouring, so that the corners are more rounded. Pay attention to find the level when pasting, and the two corners in the middle are aligned.
Third, the corner protector installation
Construction method of installing corner protector. When installing corner protectors on columns and corners, the anchor feet of corner protectors are temporarily fixed with nails or mortar, and all surfaces are consistent, and vertical adjustment and straightening are carried out before installation and fixing. The installation method of corner protector for office building decoration varies with different base materials, and the methods are as follows
1. When installed on concrete and concrete blocks, use nails or mortar anchor feet with an interval of about 300-450mm.
2. When installing on the mesh metal plate, plaster the metal mesh plate first, and then install it with hard mortar after it is fully hardened.
3. When installing on the wood structure, install it with nails or clips.
Matters needing attention in installing corner protectors in decoration construction:
1. In order to promote the hardening of anhydrous gypsum mortar, weak acid alum is often mixed. Most corner protectors are not corroded by weak acids, but the anchor feet are made of galvanized steel plates. Because the electroplating layer is not thick enough, the plastering project has just been completed, and there are examples of yellow rust around the anchor foot of the corner protector.
2. Mixed gypsum ash is usually neutral, but it is also acidic, with a PH of 8. It can be considered that this is mortar that rusts window frames. Xiao Di of Shanghai Office Decoration Company reminds us that when applying this decorative material, we should pay attention to the rust prevention treatment of the corner protector anchor feet. In addition, after plastering, brass products often produce a small amount of rust, which is not only time-consuming, but also sometimes pollutes the decoration surface. Galvanized steel plate should be decorated with oily paint or plastic paint, preferably stainless steel products.
The structure of the yin and yang corner lines of these walls should be reasonable, which will be beautiful and effective. For these problems in the decoration, we can invite professional inspectors to supervise! Tuba rabbit decoration warranty service, signed a decoration warranty agreement before construction, provided quality inspection and acceptance of key engineering nodes during construction, and issued an acceptance report after acceptance. The whole journey is free!
The above is the treatment method of the corner line of yin and yang on the wall introduced by Bian Xiao, hoping to help you. For more information about the treatment of the corner line of yin and yang on the wall, please continue to pay attention to the decoration of Tuba rabbit.
