Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of displaying a building reference line by means of a light beam, which enables the building reference line to be displayed very easily and accurately.

[0002]

2. Description of the Related Art Recently, the problems to be solved by the invention
Irradiate the laser light 360 degrees around and irradiate the surrounding area at a height of 1 m above the floor, for example, and mark it on the wall or pillar surface through which the laser light passes in line with the laser light line. The method of displaying lines is adopted.

Although this method is more convenient than the conventional method in which the height is looked into the transit, the line trace of the laser beam is still visually observed along the wall of the irradiation surface of the laser beam.
The work of stamping it is necessary.

The present invention relates to a method of displaying a building reference line by means of light rays, which can omit this point as well.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

Where a reference line is desired to be displayed, a substance sensitive to a predetermined light beam is directly sprayed or applied to the reference line,
This sensitizer is selected as an erasable photosensitizer that can undergo reversible sensitization when irradiated with a light having different properties such as wavelength from the above-mentioned light sensitizer, and the light irradiating device is activated in the attached part attached with this sensitizer. And irradiate a predetermined ray of light in a line shape to make the substance sensitive to the radiated ray of light to expose the building reference line b, and when unnecessary, irradiate the ray of light having a different property such as the wavelength of the ray and the building. The present invention relates to a method of displaying a building reference line by a light beam, which is characterized in that the reference line b is erased.

Further, the present invention relates to a method of displaying a building reference line by a light beam, wherein a laser beam a'is adopted as the light beam.

[0008]

[Function] A substance sensitive to a predetermined light ray, for example, a substance sensitive to a laser beam is directly applied or sprayed on the place where the reference line is desired to be displayed, or an adhesive tape to which the substance is previously attached is attached. To do. When the laser light irradiation device is activated on that, the laser light is irradiated onto the substance, and it will pass while drawing the line, so the place where the laser light hits appears the line in response to the laser light, This line becomes the building reference line.

When it is no longer necessary, this line is erased by irradiating it with a light beam having a property different from that of the light beam such as wavelength.

[0010]

[Examples] The light-sensitive substance is not limited to a substance which develops a color in response to a laser beam, but a substance which has a color and is desensitized in response to a laser beam is selected.

For example, photochromism changes from colorless to B color and from A color to B color by light irradiation. When another wavelength is selected, the color changes reversibly.

The following are examples of such photochromic polymers.

-Triphenylmethane-based polymer-Spirolane-based polymer-Dithizone-based polymer-Viologen-based polymer In addition, an organic photochromic compound, which has recently attracted attention as an optical information storage material, may be adopted.

For example, a photochromic polymer obtained by copolymerizing a novel spirobenzothiopyran derivative having absorption in the semiconductor laser region with MMA, styrene or the like has excellent photochromic properties.

FIG. 1 is an explanatory view showing an embodiment of the present invention, in which reference numeral 1 is a wall surface, 2 is a pillar surface, 3 is a floor surface, and 4 is a coating of the light-sensitive substance which develops color in response to light rays. Layer, a is a laser light irradiation device, a'is a laser light, b is a building reference line,
b'is a laser beam line.

Further, the laser light irradiating device a is shown as a horizontal rotary type, but the present invention is similarly applied to an embodiment in which the installation state of the rotary cylinder 6 is changed and the laser light a'is run in the vertical direction. The line irradiation of the laser beam a ′ can be designed in a reciprocating style instead of the rotating style.

[0017]

As described above, according to the present invention, a substance which is sensitive to a predetermined light beam is attached to the place where the reference line is desired to be displayed, and the light beam irradiating device is operated to the attached portion to irradiate the predetermined light beam in a line shape. However, since it relates to a method of making the above-mentioned substance sensitive to the irradiating light beam and revealing the building reference line, it is possible to irradiate a predetermined light beam horizontally by, for example, a rotating light irradiating device, and the wall or pillar surface The line can be revealed.

In addition, this operation may be performed by applying a substance sensitive to light rays by the simplest method such as spraying or coating. Moreover, the method by spraying or coating is not only simple, but the desired surface may be prepared immediately before use. It is possible to attach it to the light emitting device, and you do not have to bother to peel off the filter tape on the surface that covers the sensitive part from the light like the tape method and peel off it, just apply it just before turning on the light irradiation device switch. , Work efficiency is extremely improved.

Further, since this photosensitizer is selected as an erasable photosensitizer which can reversibly change its sensitivity when it is irradiated with a light having a property different from that of the light, the light and the wavelength can be changed when unnecessary. This is a method of displaying a building reference line by an extremely excellent light ray that can easily erase the building reference line b by irradiating rays having different properties.
