Description

[0001]
BACKGROUND OF THE INVENTION
When measuring the horizontal angle between measuring points, this invention can easily measure the horizontal angle even when the height of each measuring point is different or when the measuring point is located at the groove bottom or the like. Light generator and horizontal angle measuring method using the same, and using this horizontal angle measuring method to form the foundation and underground beam at the construction site, The present invention relates to an inking method suitable for determining a line and inking.
[0002]
[Prior art]
When measuring the horizontal angle between measuring points using transit, it is necessary to install the transit at a location where each measuring point can be easily seen. In particular, when a measuring point exists at the bottom of the excavation hole or an obstacle exists, the installation point of the transit is limited to a narrow range.
[0003]
Also, in the construction of foundations that require measurement of the water angle, if the entire area of the planned construction area is dug up, all parts to be backfilled will be dug up later, and wasteful work must be performed. Moreover, since the density of the excavated soil is coarse at the time of backfilling, the soil is left over and the soil is discarded wastefully.
[0004]
On the other hand, as shown in FIG. 2, only the area corresponding to the place where the foundation and the underground beam are embedded as shown in FIG. 1 is excavated into a grid pattern, and the bottom of the grid-shaped excavation hole of the grid pattern is shown in FIG. There is a foundation forming method in which a quarry stone 2 and abandoned concrete 3 are laid and a foundation 5 and an underground beam are concretely formed on the surface of the abandoned concrete. During the excavation, a truncated pyramid-shaped mountain 1 surrounded by vertical and horizontal streets remains as an unexcavated area.
[0005]
An example of a conventional inking method when forming such a foundation and underground beam will be briefly described.
(1) In FIG. 14, by measuring the distance and direction (azimuth) from the benchmarks B1 and B2 in the state of clear ground, the two reference rulers 30 are perpendicular to each other along the outer edge of the planned construction area. It is fixed on the ground as a safe state. Each ruler 30 is provided with a mark M at a predetermined position where a vertical street and a horizontal street are to be formed.
[0006]
(2) Install the transitions sequentially on each mark M of the ruler 30, index the vertical and horizontal streets so that they are perpendicular to the ruler 30 (parallel to other rulers), and stretch the ropes corresponding to each street, A grid-like line is drawn on the ground with lime according to the tension line. That is, “how to spend” is performed by a ruler.
[0007]
(3) Excavate in the shape of a grid with a yumbo or the like corresponding to the lime wire drawn on the ground, and place a ground reinforced concrete pile at the bottom of the excavation hole and form a discarded concrete surface.
[0008]
(4) Reinstall the transit at the mark M of the ruler 30, and again determine the vertical and horizontal streets, then throw away the foundation center position that is the intersection of both streets and mark it on the concrete surface. That is, a mark is drawn at each intersection on the discarded concrete surface.
[0009]
(5) The foundation and underground beam are formed at predetermined positions in accordance with the vertical and horizontal marking lines drawn on the discarded concrete surface and the center position of the foundation which is the intersection of them.
[0010]
(6) After forming each foundation and underground beam, again and again, sequentially set the transit to each mark M of the ruler 30 and mark the vertical and horizontal streets on the upper end surface of the foundation and the center position of the foundation. The column center position corresponding to is marked.
[0011]
(7) The base plate of the steel column is positioned and fixed at a predetermined position on the upper surface of the foundation with reference to the mark on the upper end surface of the foundation and the mark of the column center position.
[0012]
In addition, as a prior art of the horizontal angle measuring method, there is a method of directly detecting a vertical light wave generated upward using a vertical light wave generator that generates a vertical vertical light wave (for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 11-94540.
[0014]
[Problems to be solved by the invention]
In the horizontal angle measurement method using ordinary transit, for example, when measuring or measuring the bottom of the hole after excavation, the mountain in the middle is in the way. Is extremely difficult to install and, therefore, it is also very difficult to measure the horizontal angle between measurement points.
[0015]
For this reason, when the vertical and horizontal streets of the grid and the center position of the base as shown in FIG. 1 are determined, the ink marking method as shown in FIG. 14 is used.
[0016]
However, in the conventional inking method as described above, the process of determining the vertical and horizontal streets of the grid and the center position of the foundation by transit is a process of inking on the ground, and injecting on the discarded concrete surface (indian ink) Each process) and the process of marking on the upper surface of the foundation. That is, in each process, a transit must be sequentially installed at each mark of each standard ruler.
[0017]
In this way, the transition must be installed in accordance with each mark on the ruler for each process, and leveling and centripetation must be performed. In addition, because of the individual variation in the installation position and installation position of the transit due to the dredge of the worker, even if the same instrument is used, the position of the column center finally drawn on the top of the foundation is initially Often deviated from the center of the base.
[0018]
Explaining in detail, in each marking process, every time a transition is set on each mark M of the reference ruler 30, a leveling operation (leveling operation) of the transit and a centering operation (centripetal operation) by swinging down must be performed. Therefore, it takes a lot of work time to install the transit. In addition, due to the difference in the reading level of the operator's level or the level of the level of the downward swing, it is unavoidable to change the horizontal accuracy or the centripetal accuracy, and the chances of deviations in the level and centripetal level increase.
[0019]
Also, the work of adjusting the angle between the reference rulers 30 to the right angle, and the work of determining the vertical street and the horizontal street by calculating an angle of 90 ° with respect to the ruler 30 from each mark of each reference ruler 30. It takes time and effort. Furthermore, the ruler 30 must be fixed to the ground so that it remains in the same position from the time of the terrain until the foundation is completed. There are many occasions when the machine is touched, and the ruler may be misaligned.
[0020]
In addition, the method of directly visually recognizing a straight vertical light wave as described in Patent Document 1 may be difficult to detect the vertical light wave. In particular, in a dim environment or at night surveying, the vertical light wave is detected by transit. Is difficult.
[0021]
OBJECT OF THE INVENTION

Can be detected. Furthermore, since the light-emitting body 21 is visually observed, it can be measured even at night.
[0033]
[Reference example of light generator]
  FIG.Although it is not the light generator for horizontal angle measurement by this invention, it demonstrates as a reference example.Similar to the structure of FIG. 10, a light generator main body 13b is installed on a tripod 14 having a certain height and adjustable height, and a gyro-type self-horizontal holding function is provided in the main body 13b. In addition, even when the light generator main body 13b is installed in a non-horizontal posture, the vertical light wave generator 13a is kept horizontal and always has a straight vertical light wave L1 vertically downward.

The resin plate 23 is arranged in an inclined posture.
[0037]
The light generator main body 13b includes a gyro-type self-horizontal holding function and a vertical light wave generator 13a that generates vertical light waves L1 and L2 respectively on the same straight line vertically downward and vertically upward.
[0038]
The surface of the white resin plate 23 is not finished with a mirror finish, but is finished with such a degree of roughness that the upward vertical light wave L2 is irregularly reflected, thereby diverging light.
[0039]
By aligning the downward vertical light wave L1 with the mark of the measurement point F1 (or F2) on the ground, an upward vertical light wave L2 is generated on the vertical line set up at the measurement point F1 (or F2), and this upward vertical light wave L2 Hitting the resin plate 23 illuminates one point G1 on the same vertical line as the measuring point F1 (or F2) on the surface of the resin plate 23, and light diverges. This light emission point G1 is detected by the transit 10.

(2) Outside the planned construction area (excavation planned area) E, the transit 10 is installed at two arbitrary points P1, P2, and the horizontal angle measuring light generator 13 is installed at each of the benchmarks B1, B2. .
[0044]
Each transit 10 is provided with a light wave or radio wave range finder and a reflection mechanism for reflecting light waves or radio waves emitted from the counterpart transit 10, and thereby the distance and relative distance between the two transits 10. The target direction can be measured. Furthermore, a computer 11 is connected to both transits 10, and each measurement value measured by the transit 10 is input to the computer 11, and the measurement value or a numerical value appropriately calculated is stored and displayed on the screen of the monitor 12. It can be done.
[0045]
(3) The light emitter 21 of the horizontal angle measuring light generator 13 installed in the benchmarks B1 and B2 is detected by each transit 10, and the position (orientation) of the counterpart transit 10 is detected. Thereby, the distance between the transitions on the first reference line S1 connecting the installation points P1 and P2 of the two transitions 10 is measured, and the first reference line S1 and the first reference line S1 are viewed from the first installation point P1.

Conversion processing is performed into a horizontal angle α (xy) formed with the first reference line S1 viewed from P1 and a horizontal angle β (xy) formed with the first reference line S1 viewed from the second installation point P2.
[0047]
(5) In FIG. 4, the horizontal angle measuring light generator 13 is placed at an arbitrary point of the inking point, for example, the point O (33) ′ expected to be in the vicinity of the intersection O (33) between X3 and Y3. . The first transition 10 detects the light emitter 21 of the horizontal angle measuring light generator 13, thereby measuring the horizontal angle α with respect to the first reference line S 1, and at the same time the second transition 10 for measuring the horizontal angle. The light emitter 21 of the light generator 13 is detected, and the horizontal angle β with respect to the first reference line S1 is measured. These measured values are compared with the angles α (33), β (33) corresponding to the inking point O (33) calculated in advance as described above, and the difference is calculated to calculate the X-axis and Y-axis directions. Is displayed on the monitor 12 of the computer 11. The horizontal angle measuring light generator 13 is moved and adjusted by the detected difference so as to coincide with the target marking point O (33), and a mark is marked on the ground. As a result, the inking point 0 (33) serving as one basic center position is determined on the ground and inked.
[0048]
(6) Next, in FIG. 5, the horizontal angle measurement light is generated at the point O (32) 'which is expected to be another inking point O (32) on X3 in the same vertical path as the inking point O (33). The horizontal angle α with respect to the first reference line S 1 is measured by detecting the light emitter 21 of the horizontal angle measuring light generator 13 with the first transit 10, and at the same time the second transit 10. The light emitter 13 of the horizontal angle measuring light generator 13 is detected and the horizontal angle β with respect to the first reference line S1 is measured. These measured values are compared with the angles α (32), β (32) corresponding to the target inking point O (32) calculated in advance as described above, and the difference is calculated to calculate the X axis and the Y axis. It is displayed on the monitor 12 of the computer 11 as a difference in direction distance. The horizontal angle measuring light generator 13 is moved and adjusted by the detected difference so as to coincide with the target marking point O (32), and a mark is marked on the ground. As a result, the second inking point 0 (32) is determined on the ground on the vertical street X3 and inked.
[0049]
When the marking points (33) and O (32) serving as the two basic center positions are determined on the ground, the vertical street X3 can be determined, and the vertical street X3 can be marked.
[0050]
(7) In FIG. 6, the horizontal angle measuring light generator 13 is placed at a point O (53) 'which is expected to be another inking point (53) on the same side Y3 as the inking point O (33). The horizontal angle α with respect to the first reference line S 1 is measured by detecting the light emitter 21 of the vertical horizontal angle measuring light generator 13 with the first transit 10, and at the same time, the horizontal with the second transit 10. The detection light wave of the angle measurement light generator 13 is detected, and the horizontal angle β with respect to the first reference line S1 is measured. These measured values are compared with the angles α (53), β (53) corresponding to the target marking point O (53) calculated in advance as described above, and the difference is calculated. Is displayed on the monitor 12 of the computer 11 as a difference in distance in the X-axis and Y-axis directions. The horizontal angle measuring light generator 13 is moved and adjusted by the detected difference so as to coincide with the target marking point O (53) and a mark is marked on the ground. As a result, a second inking point 0 (53) is determined on the ground on the side street Y3 and inked.
[0051]
When the marking points O (33) and O (53) serving as the two basic center positions are determined on the ground, the horizontal street Y3 can be determined, and the horizontal street Y3 can be marked.
[0052]
(8) In the same manner, the remaining vertical streets X1,..., X6 and horizontal streets Y1,... Y4 are determined and printed on the ground. In the printing of all the vertical and horizontal streets, the two transitions 10 do not need to move from the first installed points P1 and P2, and do not need to be adjusted again. Then, according to the determined vertical and horizontal streets X and Y, a line is drawn in a grid pattern on the ground with lime and excavated.
[0053]
(2) A step of marking the vertical and horizontal streets and the center position of the foundation at the same position as in the case of the above landslide on the discarded concrete surface formed at the bottom of the excavation hole after excavation.
[0054]
(1) During the excavation work, both transits 10 are once removed from the installation points P1 and P2 in FIG. 6, and after excavation, they are installed again at arbitrary points P3 and P4 as shown in FIG. The installation points P3 and P4 are set irrespective of the installation points P1 and P2 at the time of the above-mentioned landslide.
[0055]
(2) As in the case of the above-mentioned lands, the transit 10 detects the light emitter 21 of the horizontal angle measuring light generator 13 and also detects the position (orientation) of the counterpart transit 10, thereby The distance between the instruments of the second reference line S2 connecting the transit 10 is measured, and the horizontal angles ∠B1P3P4 (angle α03), ∠B2P3P4 (angle α04), ∠B1P4P3 of the benchmarks B1 and B2 with respect to the second reference line S2 (Angle β03) and ∠B2P4P3 (angle β04) are measured. As a result, the installation points P3 and P4 of the two transitions 10 for the benchmarks B1 and B2 are recognized and input to the computer.
[0056]
(3) The second reference value as seen from the third installation point P3 by the computer using the numerical values on the coordinates of the basic center positions (inking points) O11, O12,..., Oxy,. Conversion processing is performed into a horizontal angle α (xy) formed with the line S2 and a horizontal angle β (xy) formed with the second reference line S2 when viewed from the fourth installation point P4. Since the horizontal angles α (xy) and β (xy) are calculated based on the third and fourth installation points P3 and P4 and the second reference line S2, it is natural that FIG. This is different from the numerical value calculated based on the first and second installation points P1, P2 and the first reference line S1.
[0057]
(4) In FIG. 8, the horizontal angle measuring light generator 13 is placed at an arbitrary point of the inking point, the point O (33) 'expected to be in the vicinity of the intersection O (33) of X3 and Y3.
The first transition 10 detects the light emitter 21 of the horizontal angle measuring light generator 13, thereby measuring the horizontal angle α with respect to the second reference line S 2, and at the same time the second transition 10 for measuring the horizontal angle. The light emitter of the light generator 13 is detected, and the horizontal angle β with respect to the second reference line S2 is measured. These measured values are compared with the angles α (33) and β (33) corresponding to the target calculation point O (33) calculated in advance, and the difference between them is calculated and the difference between the distances in the X-axis and Y-axis directions. Is displayed on the monitor 12 of the computer 11. The horizontal angle measuring light generator 13 is moved and adjusted by the detected difference so as to coincide with the target marking point O (33), and a mark is marked on the ground. As a result, the inking point 0 (33) serving as one base center position is determined and discarded on the concrete.
[0058]
(5) After that, in the case of the above-mentioned landslide, the same as steps (6) to (8) in (1), and a summing point O (xy) corresponding to the basic center position of the important point is determined and Decide street X and street Y and discard it on the concrete surface.
[0059]
(3) After building the foundation, marking the vertical and horizontal streets and the center position of the foundation on the upper end of the foundation is the same as the marking method at the time of landslide and after excavation. do not do.
[0060]
[Another embodiment]
  straightThe light emitters arranged on the linear vertical light wave are not limited to those emitting visible light, but can be confirmed by any device such as a light emitter that emits infrared rays that can be confirmed using an infrared sensing device. It is possible to diverge invisible light.
[0062]
【The invention's effect】
  As described above, according to the horizontal angle measuring light generator 13 and the horizontal angle measuring method using the same according to the present invention, the horizontal angle measuring light generator 13 is made to coincide with the measuring point by the downward vertical light wave L1. Since the illuminant 21 arranged on the same vertical line as the vertical light wave L1 is detected by a transit, the azimuth angle of the station is measured, so that the height of the station differs or the station is located at the bottom of the hole. Even if there is an obstacle or there is an obstacle between the measuring point and the transit installation point, it is possible to accurately measure those measuring points without greatly changing the vertical angle of the transit. Further, by detecting the illuminant, measurement can be performed easily and accurately even in a dim environment or at night.Further, since the linear member is used as the light emitter, the number of measurement points is reduced and the measurement site can be directly used, and the structure is simplified, as compared with the cylindrical light emitter as shown in FIG.
[0063]
In particular, when marking on the concrete surface at the bottom of the excavation hole, even if it is a hole excavated in the shape of a grid, it is installed by measuring the horizontal angle using a horizontal angle measuring light generator. Regardless of the point, it is possible to detect the light emitters on the vertical line of each measurement point, and the degree of freedom of the installation range of the transit is increased.
[0064]
According to the inking method according to the present invention, if the transit is installed at two arbitrary points, a number of inking points can be determined and inked without changing the installation position.
Therefore, compared to the conventional standard ruler method, the generation of errors can be greatly reduced compared to the case where the transition is installed at a new position for each street and leveling and centripetal adjustment are performed. can do.
