By measuring an interval between a lower part of the object to be measured and laser beam, measurement can be performed without being affected by natural phenomenon such as wind. The laser plumb bob is composed of main body cases 41 to 41a capable of avoiding wind, the shaft 5, the laser main body, and each mounting base part. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a laser capable of simplifying surveys such as the rebuilding of columns and the rebuilding of walls in a steel construction work at a construction site and the like, which can be accurately and quickly performed without being affected by wind or the like. Regarding plumb bob.

[0002]

2. Description of the Related Art Conventionally, for the rebuilding of columns for steel frame construction and the rebuilding of ALC, walls, etc. at a construction site, a plumb bob is set on the upper part of the object to be surveyed, and a weight is attached to the tip of the thread to attach the upper part and the lower part. Traditional methods of measuring the distance between the yarn and the object to be measured are used.

[0003]

[Problems to be solved] Conventionally, for the rebuilding of columns for steel frame construction and the rebuilding of ALC, walls, etc. at the construction site, a plumb bob was set on the top of the surveyed object and a weight was attached to the tip of the thread. There is an old-fashioned method of measuring the distance between the upper and lower threads and the object to be surveyed, but this method takes time because it is affected by the wind, making accurate surveying difficult. It was

In addition, when measuring the outer wall of a high-rise building, it is more susceptible to wind than in a low-rise building, and the longer the thread, the more the shaking does not stop.

[0005] Further, during the typhoon season or the seasonal wind such as winter, the conventional method is structurally difficult because the yarn receives wind and accurate measurement cannot be performed.

The present invention has been made in view of the above, and an object thereof is to easily measure a yarn of a measuring portion which is a surveying source even in a strong wind by using a laser beam which is not affected by wind. It is intended to provide laser plumb bob.

[0007]

The present invention has been made in order to achieve the above-mentioned object, and the laser plumb bob of the present invention is set on the upper portion of the object to be measured and the power is turned on to activate the laser beam. The laser function is formed so that it is exactly under the pendulum function.By measuring the distance between the laser beam of the upper and lower parts by measuring the distance between the laser beam and the lower part of the laser beam at a preset interval, the influence of the wind. It is a laser plumb bob which is characterized by the fact that it can be accurately measured without being affected by it.

In the laser plumb bob of the second invention, the position of the laser can be confirmed by adding a peep window for confirming the angle of the pendulum to the invention of claim 1, and the reference value warning lamp function and the reference value warning sound can be obtained. It is a laser plumb bob which can be confirmed by eyes and ears by using a function.

The laser plumb bob of the third invention uses the remote control function of the invention of claim 1 or 2 and a suspending base for preventing the main body from dropping outside the main body, thereby enabling surveying at a high place. It is a laser plumb bob which is characterized by being simpler.

[0010]

[Example] At the construction site, it is not affected by the wind by setting it on the upper part of the object of inclination measurement such as the pillar, wall or outer wall of the steel frame construction and measuring the laser beam interval of the lower object to be measured. It is an epoch-making laser plumb bog which is characterized by being able to measure accurately.

[0011]

EFFECTS OF THE INVENTION In the conventional steel frame construction, the inclination of pillars, walls, outer walls, equipment, etc. is measured by setting a plumb bob on the upper part and attaching a weight to the tip of the thread, and the upper and lower threads and the object to be measured. There is an old-fashioned method of measuring the distance, but with this method, the yarn is affected by the wind, so it takes time to perform accurate measurement, and the longer the yarn, the more swaying did not stop. By using the laser plumb bob of the present invention, since it is not affected by wind, accurate tilt measurement can be performed easily and the tilt can be easily corrected, resulting in improved work efficiency and improved quality. It is a plumb bob and a laser plumb bob that construction officials wanted.

The laser plumb bob has a fixed base base, an installed fixed base and an installed base separately.
The laser plumb bob may be configured to include the fixed base base, a fixed installation base, and a fixed portion engageable with the installed base member.
