If the quality of the skeleton material does not meet the requirements, 62616964757a686964616fe78988e69d8331333264643764 will directly affect the firmness of the entire skeleton, which is an important cause of cracking and deformation of the ceiling. If the quality of the skeleton material does not meet the requirements, it will directly affect the firmness of the entire skeleton, which is an important cause of cracking and deformation of the ceiling.
If the gypsum board does not meet the quality requirements, the gypsum board and the keel can not be firmly fixed, when there is an external force, the gypsum board joints will produce shear force, resulting in the cracking of the board joints.
The boom itself is bent, and after being installed for a period of time, it is gradually straightened under the action of gravity of the plate, which causes uneven subsidence of the surface layer of the auxiliary keel and gypsum board, resulting in cracks at the joints.
2.Construction reasons.
The construction process is not standardized, the construction is not in accordance with the design requirements, the construction is not in accordance with the operating procedures, the joints at the interface between the board and the board are not left according to the requirements, the large-area construction plank is not staggered, the fastening screws are short or the distribution points are sparse, the amount of caulking putty glue is insufficient or too soft, and the flat seams, yin angles, and yang corners are not pasted or wrapped in accordance with the regulations. It will reduce the overall stiffness and firmness of the skeleton, produce internal stress, cause deformation and even crack joints.
The keel layout is unreasonable, the construction is not carried out in strict accordance with the drawings and relevant national specifications, and the design parameters are changed without authorization.
Human-made. It is self-evident that the construction unit is driven by the idea of pursuing the greatest interests, reducing the quality requirements without authorization, doing tricks and feet in the construction materials, filling the small with the big, filling the thick with the thin, filling the real with the fake, and passing the shoddy with the good.
Solution: Artificially leaving cracks is a commonly used method to prevent cracks, also known as "treating cracks with cracks". The method is to artificially leave the seams, slots, staggered seams, segmented seams, and large-size board surfaces into small-sized board surfaces, so that the internal force of gypsum board is released in the board joints, and at the same time, the seams and grooves can be designed into different patterns or downgrades, so that the plane is three-dimensional and more decorative.
Before the keel installation, the main and auxiliary keel installation construction plan is confirmed to ensure that the opening position of the lamp and tuyere is not on the keel position. Reduce the phenomenon of panel cracks caused by ceiling vibration caused by the opening of the lamp and the need to cut the keel.

Deal with the seams again, and the caulking tape can be better! Then brush the latex paint!

Anonymous users2024-01-20The cause of the cracking of the production bai du:
Gypsum board ceiling joints
The seams are not cracked.
The DAO or back anti-cracking treatment is not standardized.
Answer: Solution:
1. Scrape off the putty at the joints of the gypsum board;
2. Paste kraft paper or anti-crack bandage on the splicing of gypsum board;
3. Re-scrape putty and smooth it;
4. After drying, polish the putty flat;
5. Clean the floating dust on the surface of the putty, then apply the interface agent, and then touch up the paint.

Anonymous users2024-01-19Dr. Berg: I guess it's because of the material, so let's get the ceiling down again.
Gypsum board ceilings need to be painted with latex paint. The gypsum board ceiling is the same as the blank ceiling. Gypsum board can not be directly brushed on the gypsum board, gypsum board is made of two layers of paper sandwiched with gypsum powder, direct brushing will absorb all the moisture of the latex paint into the interior of the gypsum board. >>>More
The reason for the rust is very simple, that is, when sealing the plasterboard, it is a code nail. This kind of nail works fast but will rust It is best to use self-tapping nails The nail cap has anti-rust paint, it will not rust and it is strong, it is a carpenter master It takes a little effort But now the ceiling uses self-tapping nails, and the Martin era has long been outdated.

It is caused by the lack of priming treatment or the poor quality of the priming paint, that is, yellowing. There is no approval of putty according to the construction process, the first putty is not finished when the ash is not finished, and the color will quickly penetrate outward, as well as in the primer and topcoat, the time is too short, the paint is not finished, this situation will occur, because the paint used is water-based paint, and two or three brushes will be carried out without drying thoroughly, and the color will penetrate outward with the moisture, so this will happen. >>>More
