  In the third stage, the positional relationship (distance and direction) of the first point 6 (x1, y1), the second point 7 (x2, y2), and the third point 9 (x3, y3) in the computer system. In accordance with the first point 6, the second point 7, and the third point 9 provided on the plane forming means of the actual positioning device 1, the display object (graphic icon 16) of the virtual positioning device 1 created by the computer system Is set as the input means, and this display object is arranged at the reference point d or the reference lines d1 and d2 on the computer image, so that the calculation of the point position information can be omitted. That is, the first and second graphic icons 16 serving as display objects simulating the first, second, and third points 6, 7, and 9 of the member positioning device 1 are arranged on the image of the computer system. The positions of the third points 6, 7, 9 are determined.

  That is, the graphic icon 16 is an input tool in which the first point 6, the second point 7, and the third point 9 are shown, and the interrelationship regarding the distance and direction holds the data in the storage means. Since it is arranged by the input means while maintaining the relationship, there is no need to obtain in advance by the above calculation (see FIG. 4).

  The display object is not limited to the graphic icon 16. For example, if the position and orientation of the third point 9 among the three points are input by the computer system, the predetermined positional relationship with the third point 9 is maintained by calculation processing. The remaining first and second points 6 and 7 may be automatically arranged.

  Next, the angle between the first point 6 (x1, y1) and the arrangement point 14 (xp, yp) of the pile is a line segment connecting the lines 6 and 14 in FIG. Similarly, the angle between the second point 7 (x2, y2) and the pile arrangement point 14 (xp, yp) is the same as the second point 7 (x2, y2) and the pile arrangement point 14 (xp , Yp) is obtained as an angle with respect to the reference line d2.

  As described above, since the building is arranged in parallel to the reference line d2 which is the site boundary line in FIG. 4, the angle α1 = angle β1, and the angle α2 = angle β2, as shown in FIG. The X axis, which is the coordinate axis, and the line segments 6 and 14 and the line segments 7 and 14 are calculated as angles formed with the arbitrarily determined reference line d2. In this way, the light emission information can be calculated using site survey data and coordinate values of the arranged buildings.

  Next, in an actual member installation operation, each point and each point are reproduced on the site according to point position information which is member arrangement information stored in the hard disk memory 10a serving as storage means of the computer system.

For example, as shown in FIG. 9, on the site of the actual member installation surface 23 or on the periphery thereof (site boundary line, road boundary line, site on the boundary of the adjacent land, for example, boundary pile as the site boundary point, etc.) Then, a reference point d is determined, and a reference line d2 passing through the reference point d is set. Then, the first point 6 is made to coincide with the reference point d, and the third point is arranged on the reference line d2 passing through the reference point d. The first point 6 is provided with a laser pointer 6 serving as a first light beam emitting means, and the second point 7 is provided with a laser pointer 7 serving as a second light beam emitting means. That is, in the actual member installation work, according to the point position information of the member arrangement information displayed on the display means of the computer system, with respect to the reference point d and the reference line d2 existing on the actual member installation surface 23, First, second points 6, 7 and third point 9 having laser pointers 6, 7 serving as first and second light emitting means are arranged (fifth stage).

  Next, the respective straight lines 6a passing through the reference point d stored in the hard disk memory 10a serving as storage means of the computer system and passing from the first point 6 and the second point 7 to the member arrangement point 14 with respect to the reference line d2. , 7a, the laser pointers 6 and 7 serving as the first and second light emitting means are rotated within the member installation surface 23 based on the angles β1 and β2. That is, the laser pointers 6 and 7 serving as the first and second light beam emitting means are rotated within the member installation surface 23 in accordance with the light emission information of the member arrangement information displayed on the display means of the computer system (sixth Stage). In the fifth and sixth stages, the above-described member positioning apparatus 1 can be used.

  Then, the laser beams 6a and 7a are vertically arranged at the intersections of the laser beams 6a and 7a which are the first and second light beams emitted from the laser pointers 6 and 7 which are the first and second light beam emitting means. The light receiving surface received by the surface is set by the light receiving unit 11 of the light receiving device 25 described above (seventh stage).

  Next, the core of the member is made to coincide with the position of the laser beam 6a, 7a, which is the first and second light beams of the light receiving surface 11 formed by the light receiving unit 11 of the light receiving device 25, depending on the member installation surface 23 (see FIG. In the eighth stage, the actual arrangement position of the members can be determined. In the seventh and eighth stages, the light receiving device 25 described above can be used.

  That is, at the site, as shown in FIG. 5, a reference point d is set on the installation surface 23 and a reference line d2 passing through the reference point d is set. By irradiating the installation surface 23 directly below the laser pointer 6, the laser pointer 6 serving as the first light beam point portion is made to coincide with the reference point d.

  Then, a third point portion vertically downward position detecting means (for example, a laser pointer (not shown) is irradiated directly below the installation surface 23, a downward swing is dropped, or a rod extending vertically is directed toward the installation surface 23. The reference auxiliary point 9 that becomes the third point portion is set on the reference line d2 by extending the reference point d2, and the laser pointer 7 that becomes the second light ray point portion is arranged on the reference line d2 other than the reference line d2. The positioning device 1 can be installed at a predetermined position on the surface 23.

  At this time, the flat plate 3 of the positioning device 1 is installed at a predetermined height from the installation surface 23 so as to form a horizontal plane. At this time, the second point 7 set on the image of the installation surface 23 of the member constructed by the computer system is also reproduced as the installation position of the laser pointer 7 on site.

  As the arrangement information of each member on the installation surface 23, the angle information β1, β2 of the locus of the laser beams 6a, 7a serving as the first and second rays with respect to the reference line d1 stored in the hard disk memory 10a serving as the storage means. The laser pointers 6 and 7 serving as the first and second light beam point portions are rotated by a predetermined angle in the horizontal plane by the rotation operating device 8 serving as the rotation operating means based on the laser beam and emitted from the laser pointers 6 and 7 in the horizontal direction, respectively. A position where the first and second laser beams 6a and 7a, which are the first and second light beams, hang down from the intersection of the laser beams 6a and 7a can be set as the axial position of the member.

  Further, each mounting portion 26 of the light receiving device 25 described above with reference to FIGS. 6 and 7 is mounted on the foundation pile 21 for the fixed structure, the rotary stirrer 22 for ground improvement, or the tip of the ground excavation auger as each member. Then, the laser beams 6a and 7a as the first and second light beams emitted from the laser pointers 6 and 7 as the first and second light beam point portions in the horizontal direction are irradiated onto the light receiving unit 11 of the light receiving device 25. Then, each member is moved and aligned in a horizontal direction at a position where the intersection of the laser beams 6a and 7a is formed on the light receiving portion 11, and a position where the member is suspended from the light receiving portion 11 with respect to the installation surface 23 is defined. It can be set as the axial center position of each member.

  For example, in FIG. 5, when placing a pile of a building, if the pile is on the core of the building (module core) and the outer periphery of the building is a right angle, one corner of the corner Let the part be the reference point d, one side of the outer peripheral part passing through the protruding corner be the reference line d1, and the other side be the reference line d2. And, so that the rotation center of the turntable 4 serving as the first light ray point portion comes directly above the reference point d, and the reference auxiliary point 9 serving as the third point portion comes directly above the reference line d2, Further, it is assumed that the positioning device 1 is arranged so that the flat plate 3 serving as a plane forming means is horizontal.

  Assuming the positioning of the positioning device 1 as described above, when the turntables 4 and 5 are rotated toward an arbitrary pile core, the laser beam 6a emitted from the laser pointer 6 and the reference line d2 The angle formed is β1, and the angle formed between the laser beam 7a emitted from the laser pointer 7 and the reference line d2 is β2.

  There are usually a plurality of building piles. For each pile, the angles β1 and β2 when the turntables 4 and 5 are pointed are calculated and stored in a storage unit provided in the computer 10 serving as a rotation angle signal transmitting means. Remember me. The angles β1 and β2 corresponding to the pile core position of each pile can be obtained geometrically if the distance between the reference point d and the pile core position of each pile is known from the building shape and surveying.

  When positioning the pile core position using the positioning device 1, first, the positioning device 1 is installed at a position as prepared in advance at a construction site. At that time, the height of the leg 2 is adjusted so that the laser beams 6a and 7a are not obstructed by the obstacle, the unevenness of the ground, and the height difference of the ground, and the flat plate 3 is leveled while visually checking the leveling device 3a. And fix.

  Then, an arbitrary pile is selected, and the turntables 4 and 5 are rotated according to the angles β1 and β2 calculated in advance by the computer 10 or the like. When the rotation operations of the turntables 4 and 5 are finished, the turntables 4 and 5 are fixed at the positions, and the laser beams 6a and 7a are simultaneously emitted from the laser pointers 6 and 7, respectively.

  Since the laser beams 6a and 7a intersect just above the pile core position scheduled to be piled, the intersection is confirmed by the light receiving unit 11, and the area directly below is marked to be the pile placing position. As the light receiving unit 11, laser light 6a, 7a can be visualized, such as paper or board on which the laser light 6a, 7a is easily reflected, a transparent box containing smoke, or the intensity of the laser light 6a, 7a such as a laser power meter. It is also possible to adopt one that can be quantified.

  The light receiving unit 11 is attached with a mark that can mark a position directly below the intersection where the laser beams 6a and 7a intersect, for example, a downward swing, a bar with a leveling device, a bar that expands and contracts vertically. The pile core positioning work can be performed by performing this work for all the pile driving scheduled positions.

  The light receiving device 25 attached to the tip of each member is required to have a structure that reliably hangs vertically from the axis of each member regardless of the verticality or mounting posture of each member.

  For example, at the time of pile driving work of a steel pipe pile whose member is a foundation pile 21 for a fixed structure, it is aligned with the center line of the pile in the situation just before placing the pile driving machine vertically, and the tip of the pile is shown in FIG. By installing the light receiving device 25 shown, it is possible to accurately put out the pile position immediately before construction without performing prior pile centering work until pile construction, and the pile can be placed as it is.

  In addition, at the time of column ground improvement placement work, by installing the light receiving device 25 shown in FIG. 7 that can be attached to the rotor blade (bit) portion of the construction machine, pre-pile centering work is performed until the column ground improvement work. Therefore, it becomes possible to accurately put out the construction core for the columnar ground improvement immediately before the construction, and the columnar ground improvement can be placed as it is.

  Since the steel pipe pile and the light receiving device 25 are fixed using bolts or magnets, it is easy to detach and attach to the circular steel pipe pile, so that the center of the steel pipe pile (pile core) and the center of the light receiving device 25 are connected. It becomes easy to match. In this state, the laser beams 6a and 7a serving as the first and second light beams can be received by the light receiving unit 11, and the pile core position can be set at the intersection of the laser beams 6a and 7a.

  Columnar ground improvement is a construction method that uses a heavy machine equipped with a rotary stirring mechanism with a stirring blade at the tip, stirs cement milk and ground at the current position, and constructs the columnar ground improvement.

Here, as shown in FIG. 3, the turn corresponding to the pile core position of any pile stored in the computer 10 serving as the rotation angle signal transmitting means for transmitting the rotation angle signal to the rotation operating device 8 serving as the rotation operation means. The rotation angle from the reference line d2 of the table 4 is β1. Then, the rotation angle instruction signal β1 is sent from the computer 10 to the rotary operation device 8 composed of a pulse motor (step S ₁ ).

Next, in the rotary operating device 8 formed of a pulse motor, the rotation angle instruction signal β1 is converted into an operation signal βx, which is information that allows the gear to rotate by the signal conversion drive unit 12 formed of a motor (step S ₂ ). The operation signal βx is sent to a signal conversion drive unit 12 composed of a motor, and the signal conversion drive unit 12 drives a gear driven to rotate by the motor according to the operation signal βx, and the turntable 4 rotates by βx to turn the turntable. The rotation angle from the reference line d2 of 4 is β1 (step S ₃ ). The turn table 5 is similarly angle-controlled.

  The rotation operation of the turntables 4 and 5 can be manually performed. By installing a transit (a surveying instrument for measuring the horizontal angle and the vertical angle) in the turntables 4 and 5, and manually adjusting the rotation angle, manual operation becomes possible.

  According to the above configuration, the angle between the positioning device 1 and the member installation position is calculated in advance and stored in the hard disk memory 10a or the like serving as the storage means of the computer 10 comprising the computer system, and the positioning device on the site. 1 is set, and laser beams 6a and 7a are simultaneously emitted from two laser pointers 6 and 7 to an arbitrary member, and the member installation position is shown immediately below the intersection of the two laser beams 6a and 7a.

  In addition, since the light receiving unit 11 for confirming the member installation position is simple, handling is good, and the operation time for determining the member installation position is shortened. Further, by using the positioning device 1, the member installation position finding operation and the reconfirmation work are not required in advance, and the member installation position finding operation can be performed at a time.

  Examples of the use of the present invention are as follows: positioning of building position (ground rope), displacement check of pile position after construction, confirmation of foundation rebar and steel frame position, placement instruction in large room in building (eg in office) It can also be widely used for positioning office equipment, setting up movable chairs in halls, etc.) and positioning the stage equipment.
