Abstract

PURPOSE:To carry out the work of building work by one person by remotely moving a target by the vertical rotation of a transit so that it is conformed with a collimation line, and setting one point on the extension of a datum line. CONSTITUTION:A collimating person M installs a transit T on datum lines A, B on a slab S. The collimating person M then puts a moving box 1 on the point B, collimates the transmit T, and stops its horizontal rotation to fix it. The collimating person M vertically rotate the transit T to move a collimation line L to a collimation line L1, operates a remote controller according to it, and moves the moving box 1 on a wall surface W side. After the moving box 1 is stopped in a point C, the controller 8 is operated to mark it. A point D is similarly marked on the wall surface W by utilizing a guide rail 6 set on the wall surface W.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for measuring a reference line in construction work.

[0002]

2. Description of the Related Art In construction work, generally, a floor plan is prepared on a floor slab for each floor, and a schematic plan view of pillars, walls, openings, etc. is created, so-called each floor is marked out, and a building is constructed by it. .

The basis of this actual size drawing is the measurement of the reference line, which has been conventionally done as follows.

In FIG. 6, when the points C and D are measured from the reference lines A and B and the reference lines A and B are extended, (1) the collimator M is the reference lines A and B on the slab S. Install Transit T on top.

(2) The assistant M1 marks the point B, applies a pencil tip, a convex or the like (hereinafter referred to as a target), and the collimator collimates and stops the horizontal rotation of the transit T to fix it.

(3) The assistant M1 makes a point C on the slab S.
Target the target in the vicinity.

(4) The collimator sends a signal to the assistant M1 so that the target is aligned with the collimation line L by the vertical rotation of the transit T.

(5) The assistant M1 moves the target in accordance with the signal to set the point C, and connects the points B and C to strike the black ink. Thereafter, similarly, a point D on the wall surface W is set and ink is struck.

[0009]

In order to measure the reference line by the above-mentioned conventional method, a group of two persons, the collimator M and the assistant M1, is the minimum unit even for a small amount of work. Yes, there is a problem from labor saving at the construction site and improvement in productivity.

An object of the present invention is to provide a method and apparatus for measuring a reference line in a construction work in which one person can work.

[0011]

According to the method of the present invention, a collimator mounts a transit on the reference lines A and B and collimates it by placing a target remotely controllable at a point B with a marking mechanism. After stopping and fixing the horizontal rotation of the transit, the target is moved by remote control so as to match the line of sight due to the vertical rotation of the transit, and point C is set on the extension of the reference lines A and B, and the point C is marked. Then, the same procedure is repeated to mark various points on the extension of the reference lines A and B.

The apparatus according to the present invention comprises a radio wave receiver, a target equipped with a traveling mechanism, a steering mechanism and a marking mechanism connected to the radio wave receiver, and a collimation scale, and a command radio wave for the radio wave receiver. It consists of a transmitter for transmitting and a transit.

[0013]

In the present invention, the collimator himself can move, stop and mark the target by remote control.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a target, that is, a moving box generally designated by the reference numeral 1. Main body 2 of this moving box 1
A traveling mechanism including two pairs of wheels 3 and a drive motor (not shown), a steering mechanism (not shown), and a marking mechanism (not shown) (for example, a pen-shaped ink marker) are provided in the radio receiver 4. It is connected. Also,
The main body 1 is provided with a transillumination collimation scale 5.

The traveling mechanism is capable of traveling on a considerably rough surface such as a rough concrete surface, and the weight of the moving box 1 is set to a weight that enables work under strong wind. Further, the steering mechanism is capable of finely adjusting turning and forward / backward movement so that it can be stopped at a fixed point.

FIG. 2 shows a guide rail 6 for accommodating the moving box 1 for measuring the wall surface W. A collimation window 7 of the scale 5 is formed on one side of the rail 6.

FIG. 3 shows a transmitter or remote controller 8 for the collimator M to remotely control the moving box 1. And moving box 1, remote controller 8
And the transit T constitute a measuring device.

Next, with reference to FIGS. 4 and 5, the manner of measuring the reference line will be described.

(1) The collimator M installs the transit T on the reference lines A and B on the slab S.

(2) The collimator M places the moving box 1 on the point B, collimates it at the transit, stops the horizontal rotation, and fixes it.

(3) The collimator M vertically rotates the transit T to move the collimation line L to the collimation line L1, and operates the remote controller 8 to match the collimation line L to move the moving box 1 to the wall surface W side. Move to.

(4) After stopping the moving box 1 at the point C,
The remote controller 8 is operated to perform marking.

(5) Using the guide rail 6 set on the wall surface W, a point D is marked on the wall surface W in the same manner.

[0025]

As described above, according to the present invention, the collimator himself can move, stop and mark the moving box by remote control to save labor.
