A wall positioning device for a prefabricated building

Abstract

The invention discloses a fabricated wall positioning device for buildings. The fabricated wall positioning device comprises a suction box, wherein a fixed shaft is fixedly arranged on the end surface of the front side of the suction box; two rotating swing arms are arrayed on the fixed shaft; an engagement groove with a forward opening is formed in the swing arm at the front side; and a lock device is arranged in the engagement groove. According to the fabricated wall positioning device, the thickness, of interfering with direct light, of a cover is adjusted through a curvature wheel by using the principle that the irradiation distance of the light can be limited by the cover, and the position of an end point of the light is adjusted in a readable manner, so that the machining accuracy is ensured; by adopting a suction pump-type piston structure, equipment is absorbed to a wall space by using atmospheric pressure, so that disassembly and assembly are facilitated; the principle that the center of gravity is vertically downward is utilized as a criterion of judging the vertical direction and judgment through manual visual observation is not needed, so that an artificial subjective judgment error is avoided; and the horizontal direction is determined perpendicular to a vertical line by adopting a lockable swing arm structure, so that the accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of wall surface processing and positioning, in particular to a wall body positioning device for an assembled building. Background technique [0002] In the process of home decoration, to install equipment on the wall, you need to use an electric drill to drill holes on the wall, and you need to determine the reference position of the hole before drilling. The traditional method is to use a ruler to measure, and determine the size of the hole through the horizontal and vertical dimensions. The position of the hole, whether the ruler is in the horizontal or vertical position during the measurement process, requires manual visual observation, and there is a large error. Even if a level ruler is used, manual observation is still required, and the slight inclination is difficult to see, and it is determined After the position needs to be marked on the wall, so that the ruler can be removed for the punching proces...

[0002] In the process of home decoration, to install equipment on the wall, you need to use an electric drill to drill holes on the wall, and you need to determine the reference position of the hole before drilling. The traditional method is to use a ruler to measure, and determine the size of the hole through the horizontal and vertical dimensions. The position of the hole, whether the ruler is in the horizontal or vertical position during the measurement process, requires manual visual observation, and there is a large error. Even if a level ruler is used, manual observation is still required, and the slight inclination is difficult to see, and it is determined After the position needs to be marked on the wall, so that the ruler can be removed for the punching process later

The whole operation process is complicated and slow, and the installation efficiency is low
