How to fix the waist line of wallboard
1. Before installing the contour curve of the partition, the wall surface shall be leveled and the ash layer shall be removed. For uneven walls, putty powder should be used for leveling, and waterproof architectural coatings should be applied to wet walls.
2, wooden keel ceiling with 24mm30mm wood square, control panel is suitable for * * * with plywood or plywood, ceiling keel interval should be kept at 450 ~ 600 mm ..
3. In the process of construction, the height of the graphic curve of the partition should be popped up on the cover drawing. According to the orientation of the main keel design and the position of the cushion block, tenon the wall. The penetration depth of wooden tenon should be 10mm away from the wall, and the drilling interval along the main keel is about 500 mm.
4. The main keel and its cushion block should be fixed with nails, the length of which should be 2~2.5 times of the thickness of the cushion block, and it can also be fixed with nails. The nails should be shot into the deep wall for 30~50mm, and the depth of the nails into the concrete wall is 27 ~ 32 mm The ends of the nails should not be exposed to the surface of the main keel or cushion block.
5. The control panel can be fixed without nail glue, which is convenient to assemble and faster, and there are no nail holes, so if the control panel is fixed, the graphic curve may not be fixed.
What are the selection skills of wallboard?
1. According to the type of substrate, it can be generally divided into two types: wood and plastic, among which wood can also be divided into strip aluminum profiles and their whole materials;
2. According to the manufacturing process of the substrate, it can be divided into three types: solid wood composite board, medium density fiberboard and man-made board.
3. No matter what material the substrate is made of, the surface has been produced and processed, and there are several color designs such as pure solid wood natural texture, imitation solid wood, imitation stone, manchurian ash, red teak and its red oak. According to the survey, composite solid wood flooring is the most popular in family decoration.
4. The quality of partition can be identified from both inside and outside. The key of essential quality is the strength of its surface and the firmness of adhesion between its substrate and surface. Generally, goods with high cost performance have high hardness, impact resistance and wear resistance. There is no obvious scar on the surface scraped with a knife, and there is no separation between the surface and the substrate.
5. The key of appearance quality is to check its simulation level. Cost-effective goods, real pattern design, unified production specifications and models, easy splicing and good decorative modeling. The strip partition shall be sealed with plastic and shall not be deformed.
