As shown in FIG. 14, a general method for planarly measuring the range of a building is a center line CX ₀ that marks a pillar on the floor of the lowest floor F (standard floor) to be constructed,
CY ₀ is measured and the ink is printed on the floor, and the relief ink is printed at a position slightly away from the column core. This escape ink is used as the reference lines X ₀ and Y ₀ , and the intersection is used as the reference point P ₀ , and the upper floor F is used.

The present invention is a method for optically performing the work of vertically transferring a horizontal reference line from the reference floor constructed as described above to the upper floor using a measuring instrument. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

In this embodiment, as shown in FIG. 1, the vertical laser oscillator 1 is installed at a reference point P ₀ , which is an intersection of the reference lines X ₀ and Y ₀ that are measured in a plane on the reference floor F _0. A vertical laser oscillator 1 is installed on the floor of the upper floor Fn to which the lines X ₀ and Y ₀ are transferred.
The horizontal laser oscillator 2 is installed vertically above the vertical laser oscillator 1, and the horizontal laser receiver 3 is installed vertically above the other vertical laser oscillator 1 opposite to the horizontal laser oscillator 2.

In this embodiment, as shown in FIG. 1, a vertical laser oscillator 1, a horizontal laser oscillator 2 and a horizontal laser receiver 3 corresponding to the vertical laser oscillator 1 are arranged in a quadrangle on a plane. However, it goes without saying that triangles or the like can be freely arranged according to the shape and scale of the building. In addition, when measuring a horizontal reference line that is longer than the effective distance of the laser beam, for example, the vertical laser is also applied to the intermediate reference point of the reference floor so that the intermediate reference point is located at a position shorter than the effective distance of the laser beam. Up to twice the effective distance of the laser beam by installing oscillators, installing horizontal laser oscillators at the reference points on both ends of the measurement floor, and installing horizontal laser receivers vertically above the intermediate reference point.

Similarly, by increasing the number of horizontal laser oscillating devices and / or horizontal laser receiving devices installed in the middle, it is possible to measure the horizontal reference line at a longer distance.

However, by making the vertical rotation mechanism of the horizontal laser oscillator 2 described later to be able to rotate approximately 180 ° in the vertical direction, the horizontal reference line for marking out can be reached by the laser beam emitted from the horizontal laser oscillator. In the case of a long distance that does not occur, install a horizontal laser oscillation device in the middle part and mark the horizontal reference line with the horizontal laser receiving device positioned at the other end by the above method. Then, the horizontal laser oscillator is rotated by 180 ° in the vertical direction to set the horizontal reference line in a state where the horizontal reference line set between the horizontal laser receiving device and the horizontal laser receiving device is extended backward as it is. be able to. Therefore, the horizontal reference line of the extension can be marked out by arranging only the intermediate marking device without arranging the horizontal laser receiving device at the rear side, which can dramatically improve the work efficiency. it can.

The vertical laser receiver 4 is composed of an optical sensor for detecting a laser beam, and optically detects a laser beam receiving position to send data to the arithmetic control section 403. The arithmetic control unit 403 (FIG. 6) obtains the center point of the laser beam received by the vertical laser receiver by arithmetic processing, expresses the laser beam center point in a rectangular coordinate system, and the axis of the horizontal laser oscillator is located at the coordinate point. A command is issued to control the positioning unit so that it is positioned. In FIG. 6, 401 is a level adjusting screw for horizontally supporting the horizontal laser oscillator 1 on the floor surface Fn, and 402 is a hood attached to the lower surface of the vertical laser receiver 4 and is a floor surface. It is adapted to fit into the opening of Fn. Further, the arithmetic control unit 403 may be assembled integrally with the horizontal laser oscillator, or as shown in FIG.

As shown in FIG. 2, a slide body 501 having a horizontal laser oscillator is installed, and the slide body is orthogonal to two axes (X axis-Y).
For example, a displacement mechanism such as a ball screw mechanism is used to displace and position in the axial direction. In the positioning portion shown in FIG. 7, the sliding body 501 is an X-axis direction sliding frame body 502.
Guided by a pair of Y-axis direction guide rods 503 provided above, a ball screw 50 for Y-axis driving is provided at the center of the lower surface thereof.
4 is fixed, and the ball screw is driven by the Y-axis drive motor 505, whereby X
It is possible to arbitrarily slide on the axial sliding frame body 502 in the Y-axis direction. The X-axis direction sliding frame body 502 is a pair of X-axis direction guide rods 507 provided on the machine frame 500.

It is configured to drive to determine a horizontal position.

As the vertical rotation mechanism 7, any mechanism can be adopted as long as it can arbitrarily control the undulation angle of the horizontal laser oscillator 8. For example, as shown in FIG.

In the embodiment shown in FIG. 8, the undulation angle of the horizontal laser oscillator mounting base is detected by the angle detector 706, and the motor can be remotely controlled by, for example, a remote controller based on the detected data. The undulation angle of the horizontal laser oscillator can be arbitrarily controlled remotely. In FIG. 8, reference numeral 707 denotes a horizontal laser oscillator mounting base 702.
It is an angle plate attached to, and the undulation angle of the horizontal laser oscillator can be detected by detecting the position of the angle plate with an angle detector.

The rotation angle of the vertical rotation mechanism 7 is such that, when a horizontal laser receiving device is arranged in the front to mark out a horizontal reference line, the horizontal laser oscillator directs a laser beam from the horizontal direction to the intermediate marking device. So that it can be illuminated
The angle may be such that it can rise and fall within approximately 90 °. However, by constructing the horizontal laser oscillator so that the vertical plane can be rotated 180 ° from the front horizontal direction to the rear horizontal direction, as described above, even if the horizontal direction light receiving device is not installed in the rear direction, It is possible to mark the standard. Vertical rotation mechanism enables horizontal laser oscillator 1
By rotating by 80 °, the optical axis does not shake before and after the rotation, and it is possible to accurately and easily extend the horizontal reference line, which is difficult with the horizontal rotating mechanism.

On the other hand, the horizontal laser receiver device 3 is
As shown in FIG. 9, the vertical laser receiver 4, the positioning unit 5, the attitude control means, and the horizontal laser receiver 9 are assembled in this order. Since the vertical laser receiver 4, the level adjusting screw 401, the hood 402, and the positioning unit 5 have the same configurations as those of the horizontal laser oscillator device 2, the same reference numerals are given and detailed description thereof will be omitted.
Further, the attitude control means of the horizontal laser receiver device 3 is composed of a horizontal rotation drive unit for rotating the horizontal laser receiver 9 about the vertical axis, and the horizontal rotation drive unit also serves as the horizontal laser oscillator device 2.

Reference numeral 17 denotes a marking line formed on the outer surface of the case 11 for displaying the vertical direction of the Y axis of the laser light receiving unit 12, and the marking start point indicating unit 16 is provided on the extension of the marking line. ing.

Next, the operation of transferring the vertical and horizontal reference lines from the reference floor Fn to the upper measurement floor Fn by using the above-mentioned respective devices will be described with reference to FIGS. .

For example, as shown in FIG. 1, the ground ink having four reference points P _{0 a to} P ₀ d in which the orthogonal coordinate axes X ₀ and Y ₀ of the floor of the reference floor F ₀ intersect is placed on the upper floor. If transferred, standard floor reference point P ₀ a~P ₀ d vertically degree measurement laser oscillator 1 and the inside of each through-hole 30 passing through the floor of the measurement floor Fn
(FIG. 4), for example, the horizontal direction laser oscillation device 2 is provided at the vertically upper portion A of the reference point P ₀ a on the reference floor, and the vertically upper portion B of the reference points P ₀ b and P ₀ c adjacent to the horizontal laser oscillation device 2. A horizontal laser receiving device 3 is further installed at C, and a horizontal laser oscillator 2 is installed vertically above the reference point P ₀ d on the diagonal.

In this state, the verticality measuring laser oscillator 1
When the laser beam Sv is oscillated more vertically, the vertical laser receivers 4 of the horizontal laser oscillator 2 and the horizontal laser receiver 3 installed on the through hole 30 penetrating the floor of the measurement floor Fn cause the laser beam Sv. To sense. The vertical laser receiver 4 recognizes the light receiving position on the orthogonal coordinates, sends the received light data to the arithmetic control unit 403 to calculate the central position of the light reception, and the horizontal laser oscillator to the positioning unit 5 based on the calculated value. 8 or a command to displace the axis of the horizontal laser receiver 9 to the light receiving center position, and the command causes the sliding body 501 to slide in the XY directions.
It is automatically positioned at the vertically upper position. Therefore, the horizontal laser oscillation position of the horizontal laser oscillator is automatically positioned vertically above the reference points P ₀ a and P ₀ d on the reference floor, and the reference points Pna and Pnd are fixed. Similarly, the reference points Pnb and Pnc are also determined, and the reference point P ₀ a on the reference floor is determined.
~ P ₀ d is automatically and accurately transferred to the measurement floor Fn.

Next, from the horizontal laser oscillator 8 of the horizontal laser oscillator 2 located at the reference point Pna to the horizontal laser receiver 9 of the horizontal laser receiver 3 located at the adjacent reference point Pnb. The horizontal laser beam Sh is oscillated and is received by the horizontal laser receiver 9.
The reference point Pna and the reference point Pnb are set to the horizontal laser beam Sh.
The sides of the quadrangle are determined by connecting them with. Similarly, the reference points Pnc and Pnd are also connected by the horizontal laser beam Sh. The XY coordinate point of the horizontal laser receiving position in the horizontal laser receiver can be transmitted through the arithmetic control unit and displayed on the liquid crystal panel of the remote controller (hereinafter, simply referred to as remote controller) H. It is like this. Therefore, in the collation, while looking at the liquid crystal panel of the remote controller H, the keys of the remote controller or the joystick are operated to rotate the horizontal rotation drive unit 20 of the horizontal laser oscillator 2 and the laser receiver of the horizontal laser receiver. By controlling the attitude of the horizontal laser oscillator so as to receive light at the light receiving center position of 9, it is possible to accurately connect the reference points Pna and Pnb and Pnc and Pnd with a laser beam by remote control. The horizontal laser beam thus set coincides with the vertically upward position of the reference black ink on the reference floor.

Next, the laser beam oscillated from the horizontal laser oscillator is received by the laser beam receiving section 12 of the intermediate marking device 10 installed between the horizontal laser oscillator 2 and the horizontal laser beam receiver 3. In addition, the vertical rotation mechanism is operated by remote control from the remote controller H to control the undulation angle of the horizontal laser oscillator 8 so that the laser beam is received by the laser receiving section of the intermediate marking device (FIGS. 3A and 3B). reference). Upon receiving the laser beam, the intermediate marking device 10 calculates the coordinate 18 in the X direction with respect to the vertical direction of the laser light receiving unit 12 and displays the coordinate position 20 on the position display unit 14. The measuring operator reads the coordinates, measures the numerical values of the coordinates from the vertical marking start point portion in the lower portion of the position display unit 14, and marks the base point t on the floor.

Since the distance between the reference points is long, a plurality of intermediate base points t
_When it is necessary to mark ₁ , ₁ , t ₂ , t _3, ..., The intermediate marking device 10 is moved to a position separated by a predetermined distance as shown in FIG. By the next intermediate base point t
To mark the _2, t _{3 ····.} A plurality of intermediate marking devices may be installed in advance at predetermined intervals, but the number of devices may be reduced by moving one intermediate marking device in order. The horizontal reference line Xn is formed by striking ink on the floor between the base points t ₁ , t ₂ , t _3, ... Obtained on the floor thus obtained.

Next, as shown in FIG. 1B, the reference point Pna
The horizontal laser oscillator 8 of the horizontal laser oscillator 2 in the position and the horizontal laser receiver 9 of the horizontal laser receiver 3 in the reference point Pnc position face each other by operating the remote controller so that they face each other. The reference line Yn is determined by rotating the rotary drive unit by 90 ° and performing marking between the reference points Pna and Pnc and between the reference points Pnb and Pnd through the same operation as described above. It is formed.
In this way, a quadrilateral mark is formed on the upper floor. The quadrilateral is congruent with the quadrilateral ground ink formed on the standard floor, and is positioned vertically above the ground ink, and the ground ink on the standard floor is accurately transferred to the upper floor. . Similarly, as shown in FIG. 4, the horizontal laser oscillator and the horizontal laser receiver are sequentially moved to and installed at the upper floors to mark the upper floors F ₁ , F ₂ , ... Fn. Can be done easily and accurately by one person.
