Description

Description: TECHNICAL FIELD The present invention relates to a construction method for vertically laying a construction member such as an outer wall member, particularly in a work of laying an outer wall member in a construction work or the like.

[Prior Art] Conventionally, as shown in FIG. 10, a down swing B is hung down from an upper portion of an outer wall member W, and a tilt of the down swing B is caused by a scale S at a lower portion, as shown in FIG. Was being measured.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional method, the down swing oscillates due to the wind, which makes measurement impossible, and even if there is no wind, it takes a considerable amount of time until the down swing sways. In addition, there is a problem that a person who adjusts the fastener of the outer wall member and a person who measures the change of the plumb bob require at least two workers.

The present invention has been made in order to solve the above-mentioned conventional problems, and an object of the present invention is to provide a construction method capable of quickly and accurately installing a building member vertically with a small number of people using a laser level. To provide.

[Means for Solving the Problems] According to the vertical construction method of a construction member of the present invention, a laser beam is rotated in a 360 ° direction and emitted, and the trajectory plane of the rotational emission of the laser beam is parallel to a reference line and The laser beam is adjusted so as to be vertical, and a photodetector is attached to a construction member such as an outer wall member, and the laser beam is received, and the laser beam is installed on a pillar or a beam.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a laser level;
As shown in the enlarged view, the rotating radiating section 1a rotates 360 °.
To emit a laser beam R in all directions on a vertical plane.

Reference numeral 2 denotes a mounting table, which can securely mount the laser level 1 even if there is an obstacle such as a reinforcing bar at the installation location. Leveling screws 2b are attached to the legs 2a of the mounting base 2.
Is provided so that the mounting table 2 can be finely adjusted to be horizontal.

Reference numeral 3 denotes a measure, which is drawn out of the measure accommodating portion 3a, and the distance between the reference needle 3b and the laser beam R, that is, the laser beam R
The distance of the radiation surface from the reference line can be easily measured.

Referring again to FIG. 1, reference numeral 4 denotes a collimation position display device. As shown in an enlarged manner in FIG. 3, a pole 4b is erected vertically on an auto pole 4a, and a light receiving mount is mounted on the pole 4b. 4c is provided and a light receiver is attached.

Reference numeral 5 denotes a collimation position display panel, which is mounted on the upper part of the auto pole 4a, and provided with an indicator light 5a and a warning light 5b.

A control unit 6 is connected to the light receiver (not shown) mounted on the light receiver mounting table 4c and the collimation position display panel 5, respectively.

 7 is a target.

As is clear from FIG. 1, a receiver mounting frame 8 is mounted on the fastener F of the outer wall member W, and a light receiver 9 is set on the receiver mounting frame 8. As shown in the enlarged view of FIG. 4, the receiver mounting base 8 includes a magnet 8a adsorbed to the fastener F, an arm holding portion 8b that is adjustable and fastened to a shaft of the magnet 8a, and an arm 8b. An arm which is pivotally attached to the holding portion 8b and has a convex portion 8b 'and on which the light receiver 9 is set.
8c.

Next, a description will be given of a method for vertically placing construction members by the measurement system of the above embodiment.

First, as shown in FIG. 5, the laser level 1 is installed using the measure 3 so that the laser beam R emitted from the rotating radiation section 1a is located at a distance X from the reference line A.

Subsequently, as shown in FIG.
The collimation position display device 4 is set at another position away from the reference line A so that the pole 4b is located at a distance X from the reference line A.

The direction of the laser level 1 is adjusted so that the laser beam R emitted from the laser level 1 is parallel to the reference line A so that the laser beam R comes to the center 7a of the target 7 attached to the pole 4b. . (7th
When the laser beam R is aligned with the center 7a of the target 7, as shown in FIG. 8, the receiver 10 is mounted on the receiver mount 4c.
Is adjusted so that the center of the light receiver 10 is located at a position X away from the reference line A by the same distance X as the laser level 1 and the pole 4b.

Next, the laser beam R is rotated, and the radiation direction of the laser beam R is adjusted so that the laser beam R passes through the center of the light receiver 10.

When the laser beam R passes through the center of the light receiver 10, the light receiver 10 and the collimation position display device 4 are connected and attached to the pole 4b. (Refer to FIG. 9.) Subsequently, the power of the collimation position display device 4 is turned on, and the position of the light receiver 10 is adjusted so that the middle indicator light 5a is turned on.

Finally, a light receiver mounting base 8 is mounted on the upper part of the outer wall member W, and the laser beam R is received by the light receiver 9 set on the light receiver mounting base 8, so that the verticality of the outer wall member W is reduced. measure.

Note that the collimating position display device 4 includes a warning light 5b for displaying a state in which the laser beam R is out of collimation.

[Effects of the Invention] (1) Since a laser level is used, vertical measurement of a building member can be performed over a wide range.

(2) Once the installation is performed, the construction members can be attached and the verticality can be measured by one person.

(3) Since the collimated position of the laser can be confirmed from a remote position, even if the laser level is deviated, the measurer finds a measurement error.
