Description

Technical Field [0001] The present invention relates to a grid-

The present invention relates to a laser level irradiating device for setting the position of a wire inlet of various lighting equipment or the like on the ceiling slab side when constructing a building or setting a construction position of a ceiling slab when a ceiling is installed, And more particularly to a lattice displayable laser level irradiating device capable of irradiating the ceiling slab side in a lattice form during laser irradiation, thereby facilitating the positioning operation.

It is one of the important conditions for the performance and durability of these structures that the structures are horizontally and vertically aligned with respect to the direction of gravity at the time of construction of the structure.

Therefore, in the fields of architecture and civil engineering, precise setting of horizontal and vertical positions (reference lines) in space is one of the important tasks.

As described above, the work method adopted by the conventional method for setting the horizontal and vertical reference applied to the construction work of the building is as follows. When measuring the vertical for the vertical construction of the support, or when setting the vertical point, Or the vertical point is set. In order to horizontally construct the floor surface, a horizontal measurement or a horizontal point is set by using a horizontal ruler or the like.

Such a conventional vertical and horizontal setting method is a method of artificially hanging a line on the ceiling, which is difficult and dangerous, and it is difficult to expect an accurate setting due to the shaking of the line, It has problems such as inconvenience, lack of promptness and accuracy because it works by moving the place from time to time.

In contrast to this, the horizontal reference is measured at the center position of the bubble formed in the glass tube filled with the liquid, and the horizontal reference is measured and positioned at a predetermined position by using a thread or a steel wire in accordance with the horizontal plane. Then, It is necessary to establish a vertical reference by hanging a weight on a thread or the like as described above in order to construct a vertical line and to build a column or the like based on the vertical reference. A horizontal indicator (level meter) for measuring the horizontal position of the bubble in the liquid tube and a vertical indicator for measuring the vertical by forming a thread and additional vertical line by hanging the weight on the thread as described above.

Therefore, in order to perform the horizontal and vertical work required for the construction, maintenance and other works of various structures such as welding of large structures of existing construction, civil engineering, shipbuilding, large scale and art works, etc., Therefore, it is possible to microscopically view the level system at each position as well as a considerable amount of time and work required for the installation and position change of the apparatus. However, when the work object is large, it is difficult to observe macroscopically. There is a problem that many difficulties follow.

As a means for solving such problems, a laser display device or the like has been disclosed, which displays a laser point rather than a laser beam line. In the case of a device for displaying a laser beam line, And it is acting as a factor to lower the productivity at the work site.

An apparatus for setting horizontal and vertical lines using a laser beam is an example of a horizontal and vertical line indicator using a laser, which is Korean Patent Registration No. 415318.

However, when the apparatus is moved to another place or an operation such as a change of position is performed, it is possible to set the vertical and horizontal lines in the horizontal and vertical line indicators according to the prior art It is necessary to pay attention to the use because it is impossible to avoid impact with the internal structure because the weight is added to the free pendulum motion. It is important to reduce the service life due to the occurrence of parts breakage due to the impact of internal components, There is a problem in that an increase in cost and the like is inevitable.

In addition, when the horizontal and vertical line indicators according to the known technology are used, horizontal and vertical lines are set in a state of being touched to the ground by a tripod or the like. In addition to the setting position in contact with the ground in the construction site, There is a problem that it becomes difficult to perform the work if it is necessary to set the horizontal and vertical lines at a certain height of the building or other structures.

In addition, when the horizontal and vertical line indicators and the three-legs are used in combination with the publicly known technology, fine adjustment is inevitable because the horizontal and vertical line movement ranges displayed on the object are small even when the horizontal and vertical lines are set on a long distance. There is a problem to be done.

On the other hand, in the case of the above-described prior arts, techniques for setting the horizontal position on the floor of the building or techniques for positioning the floor on the ceiling slab side are not explained or disclosed.

In other words, there has been a great deal of work to be done after selecting installation positions of ceiling slabs such as indoor lighting of buildings or other system air-conditioners. However, only technologies that are limited to setting points on the floor as before are disclosed In the case of selecting the location of the installation work of the ceiling slab, it relies on manual pointing operation.

On the other hand, a laser is vertically and horizontally illuminated in the interior of a building by a laser module in a laser horizontal and vertical measurement device capable of point indication, which is a patent registration No. 10-1037407, Is disclosed.

Even in the case of the patent of the main cause, there is a problem that it is limited to only the limited number of points that can be displayed on the wall surface of the indoor building.

In addition, even if laser irradiation is performed on the ceiling slab side by using the above-mentioned patent or the like, area division is impossible and accurate display on the ceiling slab surface becomes difficult, and a worker has difficulty in working such as displaying the ceiling slab manually Has existed.

Korea Patent No. 415318 Korean Patent Registration No. 1037407 (Notice of May 30, 2011)
