At present, the wall surface is leveled by adopting a screed. Wherein, the steps of punching and leveling are as follows: dotting: and (3) finding a base point on the wall surface by using a gypsum cake, connecting the base point with the point, vertically connecting the base point with the point to form a line, and calibrating by using a level meter. Rib punching: the guiding rule is held to lean against the gypsum cake, and a rib vertical to the ground is punched out. And repeatedly dotting and punching ribs to form a plurality of ribs in parallel on the wall surface. After the construction is completed, a plurality of ribs arranged side by side can be reserved on the wall surface, and then the ribs are waited to be dried and hardened. Filling and leveling: filling up the vacant space with gypsum, scraping and compacting from bottom to top by taking the guiding ruler.

When dotting with the gypsum cake, need make the point be connected with the point to need with the spirit level calibration, just can accomplish the dowel, this process is very loaded down with trivial details, hardly makes the structure of the dowel of being convenient for fast. After the rib punching is finished, the situation that the rib is deformed easily due to the separation of the guiding ruler is solved. And the rib punching process is easily influenced by manual experience, so that the flatness and the verticality of the outer surface of the rib are not enough, and finally, the wall surface leveling is easy to have a large error, so that the leveling construction precision is limited, and the condition that the wall surface flatness is not enough is easy to exist. And when filling and looking for at level, because the roughness on rib surface is great greatly, and the width of rib is also great, the rib can play great frictional resistance to the guiding rule like this to easily lead to the guiding rule to scrape the resistance of wiping very big, and then can not scrape fast and trowel, this efficiency and the quality that easily influences the wall and make level. Therefore, the existing punching and leveling has the problems of complicated site construction, insufficient precision, low construction efficiency and the like, so that the efficiency and the quality of house decoration are easily influenced.

Meanwhile, when the flatness of two wall surfaces forming the internal corner is poor or poor, the flatness and straightness of the internal corner are easily affected, so that the conditions of poor flatness, deflection, inconsistent upper and lower angles and the like of the internal corner are easily caused. And when the wall surface flatness is poor or poor, gaps are easy to appear between furniture placed close to the wall and the wall surface, so that the wall surface is easy to be uneven and inclined, or the furniture is easy to fall down, poor visual perception is easy to bring, and the grade promotion of a house is influenced. Moreover, mosquitoes, dust, sundries and the like can easily enter the gap, and the indoor sanitation can be ensured only by frequently cleaning the inner side of the furniture, which is easy to bring inconvenience to indoor cleaning.

In view of the above problems, it is necessary to design a pre-embedded reentrant corner line to improve the efficiency and quality of reentrant corner formation.
