Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel frame guiding system using a tracking type range finder and angle measuring device, and more particularly to a system for guiding a steel frame in a steel frame to an accurate design position in a construction work.

[0002]

2. Description of the Related Art An example of steel guiding in a conventional construction method is as follows. (1) The steel frame to which the straightening means such as the straightening wire is attached is erected in an approximate position in advance. (2) Fix the steel frame with temporary bolts without tightening the steel frame. (3) Using a transit and a tape measure, put out the ground ink at the steel position in a plane on the ground, measure it with two transits from the orthogonal direction with the ink as the intersection, and strain or straighten the wire. By relaxing, the steel frame is set to the normal (X, Y) position. (4) With respect to the level, measurement is performed from another direction, and the steel frame is set to the regular Z position.

The procedure of the method using a total station (hereinafter, also referred to as a distance measuring / angle measuring device) was as follows. (A) The steel frame to which the straightening means such as the straightening wire is attached is erected in an approximate position in advance. (B) Measure the position of the steel frame with a collimation type (not automatic) rangefinder / angle finder, and instruct the operator who performs the warping of the steel frame about the amount and direction of tension or relaxation that should be applied to the wire. To determine the normal (X, Y, Z) position.

[0004]

However, in the conventional method for guiding a steel frame, when the steel frame is erected, the measurement cannot be performed unless the steel frame is fixed (or stopped) once, and the measurement result is used. After moving the steel frame to the proper position, it is necessary to stop the steel frame again and perform measurement, and this work must be repeated several times, which requires time-consuming and labor-intensive work. There was a problem.

Therefore, it is an object of the present invention to install a moving steel frame .
It is to provide a steel guiding system using a tracking type range finder / angle finder that can be reliably positioned by a small number of people in a short time in the coordinate system.

(E) Reflector plate 2 accurately attached to required point 1A
When the steel frame 1 having an arrow moves closer to the mounting position by a moving device 8 such as a crane (FIG. 1 shows only the hanging rope of the moving device), the tracking type rangefinder / angle finder 4 is reflected by the light beam 5. The plate 2 is captured, the distance to the reflection plate 2 and the azimuth angle are continuously and automatically measured, and the measurement coordinate (C) of the reflection plate 2 is output via the coordinate calculation means 21.

It is displayed as a comparison with the measurement horizontal coordinate (E), and the vertical component of the difference (R) is displayed as a comparison between the design vertical coordinate (A) and the measurement vertical coordinate (H) (see FIGS. 2, 3 and 4). .

(G) Preferably, the signaler 18 near the steel frame in the building is provided with the indicator 6 consisting of a portable indicator called a handy terminal, and the two-component indicator means (6A, 6B) is provided to this. ) Is mounted, the difference detecting means 22 is included in the computer 3, and the portable display 6 and the computer 3 are connected by the radio wave 17 by the wireless transmitter / receiver 7 (see FIG. 3). The difference (R) is divided into a horizontal component and a vertical component so that they can be viewed online and in real time at the same time.

(H) In the case of the illustrated example, the signaler 18 and the operator guide the steel frame 1 by operating the moving device 8 so that the difference (R) becomes zero. When it is confirmed that the horizontal component and the vertical component of the difference (R) are both zero or decreased to a predetermined allowable value or less at the same time, it is determined that the required portion 1A of the steel frame 1 has reached the normal position, that is, the design coordinate (D). Fix 1 and tighten completely. As a result, the guiding operation of one steel frame 1 or beam is completed, and the same guiding is repeated for the next steel frame 1.

It can be reliably positioned in a small number of people in a short period of time to the target. (2) It is not necessary to separately attach a jig such as a straightening wire in the conventional method, and therefore cost can be reduced. (3) Since the mounting position coordinates of each steel frame can be handled as data, especially in the case of a steel frame, such as a cantilever, which is heavily weighted during subsequent construction and has a large amount of deformation due to bending, etc. Preliminary measures such as calculating the amount of deflection and shifting the regular position from the normal position in the direction opposite to the deflection and fixing the steel frame are possible. It enables detailed construction management and quality control, including such preliminary measures. (4) Since the design coordinates of the steel frame mounting position are held as a database, it is possible to automatically measure the finished shape after the building is completed.
