Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a down-swing level with a laser.
[0002]
[Prior art]
A laser-equipped level that has been commercially available or rented from the past is a prismatic level equipped with horizontal and vertical bubble tubes, and has a long laser radiation opening. It is used to check the horizontal and gradient of block stacking, piping, U-groove installation, etc. while watching, or to check whether the horizontal or gradient is the same from the installed structure. In addition, when working with the water string on the stringer that serves as the reference for height and street, you can get accurate work by touching the water thread with your hand, feet, or body, breaking the thread, or loosening the thread. There wasn't.
[0003]
In addition, surveying equipment such as theodolite was installed on the survey point, and in order to confirm the position, it was hung down the bottom of the center of the surveying instrument, but the surveying instrument moved up and down each time. It was very inconvenient because I had to adjust the length of the swinging yarn.
[0004]
A downward swing is used when looking at the vertical when assembling the formwork, but the length of the thread has to be adjusted, and it has been difficult for the wind to blow and position the thread.
[0005]
[Problems to be solved by the invention]
This plan was invented on the basis of the technical background as described above, and anyone can easily perform horizontal, vertical, gradient, and swivel operations with the laser swing-down leveler of the present plan. The purpose of this is to be able to use a convenient laser-equipped horizontal swing leveler that can give point indications in presentations at low cost and optically in a wide range of fields.
