Description

[Technical field]

[0001] The present invention relates to a concrete structure completed shape measurement device and a concrete structure completed shape measurement method, and more particularly to a concrete structure completed shape measurement device and a concrete structure completed shape measurement method that can improve the efficiency of the work of measuring the completed shape of a concrete structure. [Background technology]

[0002] In the construction of a concrete structure, after pouring the concrete and allowing it to cure for a specified period of time, the finished form is measured to confirm whether the concrete structure is within the tolerances set out in the design documents, and the finished form is managed.

[0003] For example, when managing the as-built condition of concrete railings in new bridge superstructure construction, the width and height of the railings are measured. However, currently, all dimensions are measured by workers using spirit levels, tape measures, convex axes, etc., which makes the as-built measurement work inefficient.

[0004] On the other hand, 10,000m 3 The above civil engineering work is managed by TS (Total Stage In this paper, a light wave method is used for shape management (see Non-Patent Documents 1 to 3).

[0005] However, using lightwave methods such as TS to control the finished shape of concrete structures such as concrete wall parapets is too large-scale and therefore inefficient. [Prior art documents] [Non-patent literature]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0040] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0041] (1) First embodiment (1-1) Configuration and measurement principle Fig. 1 is a front view showing a model of the finished shape measuring device 10 according to the first embodiment of the present invention, Fig. 2 is a perspective view showing a moving body 40 used in the finished shape measuring device 10, Fig. 3 is a front view showing a model of a wire encoder 12 and its accessories used in the finished shape measuring device 10, and Fig. 4 is a cross-sectional view taken along line IV-IV in Fig. 3. In Figs. 3 and 4, the framework structure 28 of the finished shape measuring device 10 is drawn with a virtual line (two-dot chain line).

[0042] In addition, in the explanation of the finished shape measuring device 10 according to the first embodiment, the explanation is directed to the case where the finished shape dimensions of a concrete wall parapet of a bridge are measured, however, the concrete structures to be measured in the present invention are not limited to the concrete wall parapets of bridges.

[0043] The finished shape measuring device 10 according to the first embodiment includes two wire encoders 12, a contact measuring tool 20, a laser oscillator 26, a framework structure 28, a camera 30, and a moving body 40.

[0044] Laser oscillator 26 is a device that irradiates a line laser light onto the concrete structure to be measured (here, wall parapet 102), is attached to framework structure 28, and serves to mark guidelines on the outer surface of the concrete structure to be measured. In the completed form measuring device 10 according to the first embodiment, laser oscillator 26 oscillates the line laser light so that a plane including the line laser light irradiated from laser oscillator 26 is perpendicular to the outer surface of the concrete structure to be measured onto which the line laser light is irradiated.

[0045] Wire encoder 12 is a device that outputs an electrical signal based on the length of wire 12A drawn out, and has the role of measuring the position coordinates of a point on a guideline marked on the outer surface of the concrete structure to be measured (here, wall parapet 102) by irradiating it with a line laser light by laser oscillator 26. Wire 12A can be freely drawn out from and stored in housing 12X of wire encoder 12.

[0046] Two wire encoders 12 are provided in the finished shape measurement device 10, and each wire encoder 12 is attached to the framework structure 28 so that it can rotate about the corresponding axis 14. The distance between a point on the guideline (a point on the guideline against which the tip 22A of the contact 22 abuts) and the axis 14 of the wire encoder 12 can be calculated based on the drawn-out length of the wire 12A.

[0047] Either an absolute type or an incremental type can be used as the wire encoder 12. Furthermore, the material of the wire 12A of the wire encoder 12 is not particularly limited, and specifically, for example, a stainless steel wire or a plastic-coated stainless steel wire can be used as the wire 12A.

[0048] Each of the two wire encoders 12 includes, as accessories, two pulleys 16 (pulleys 16A and 16B) and corresponding shaft members 16A2 and 16B2, and a base plate 18. As shown in Fig. 3 and Fig. 4, the wire encoder 12, the two pulleys 16 (pulleys 16A and 16B), and the shaft members 16A2 and 16B2 are attached to one surface of the base plate 18, and they rotate together about the axis 14 as a central axis. In other words, the housing 12X of the wire encoder 12 and the base plate 18 hold and store the wire 12A used for measurement, and serve as a starting point for drawing out the wire 12A, and the housing 12X of the wire encoder 12, the two pulleys 16 (pulleys 16A and 16B), and the shaft members 16A2 and 16B2 are attached to the base plate 18, and they rotate together about the axis 14 as a central axis. Therefore, the housing 12X and base plate 18 of the wire encoder 12, as well as the two pulleys 16 (pulleys 16A, 16B) and shaft members 16A2, 16B2, can be regarded as the measurement main body 11 when performing measurement using the wire 12A. The finished shape measurement device 10 according to the first embodiment is equipped with two wire encoders 12 and two measurement main bodies 11.

[0049] The axis 14 is the axis of the rotation center of a bearing mechanism 18A (see FIG. 4) that rotatably attaches the wire encoder 12 to a framework structure 28, and is an imaginary axis. As shown in FIGS. 3 and 4, the wire encoder 12 is attached to one surface of a base plate 18, and a bearing mechanism 18A is attached to the other surface of the base plate 18. The rotation center of the bearing mechanism 18A attached to the other surface of the base plate 18 is the axis 14. The other portion of the bearing mechanism 18A (the portion opposite to the base plate 18) is attached to the framework structure 28, and the wire encoder 12 is attached to the framework structure 28 via a shaft portion 18A1 (see FIG. 4) of the bearing mechanism 18A that is provided with the axis 14 of the bearing mechanism 18A as the central axis and is rotatable around the shaft portion 18A1. In addition, the bearing mechanism 18A is attached to the other side of the base plate 18 (the side opposite to the side on which the wire encoder 12 is attached) so that the axis 14 of the bearing mechanism 18A is located at a position passing through the center of gravity of the entire housing 12X of the wire encoder 12 and the accessories of the wire encoder 12 (base plate 18, two pulleys 16 (pulleys 16A, 16B) and shaft members 16A2, 16B2), i.e., the center of gravity of the measurement main body 11.

[0050] Moreover, axis 14 extends in a horizontal direction perpendicular to base plate 18, and the wire 12A drawn straight from wire encoder 12 passes through a vertical plane when it is rotated about axis 14. Furthermore, axes 14 of two measurement main bodies 11 are parallel to each other.

[0051] The material of the base plate 18 is not particularly limited as long as it has predetermined mechanical properties. Specifically, the base plate 18 may be, for example, a metal plate such as a steel plate.

[0052] The two pulleys 16 (pulleys 16A, 16B) are attached to a base plate 18 via shaft members 16A2, 16B2, respectively, so as to be rotatable about the central axes thereof. As shown in FIG. 3, the two pulleys 16 (pulleys 16A, 16B) have the role of changing and adjusting the pull-out direction of the wire 12A of the wire encoder 12. The pulley 16A, which is located close to the wire encoder 12, is located at a position such that the wire 12A (this part of the wire 12A may be referred to as the initial pull-out wire 12A1) pulled straight out from the wire outlet 12B of the wire encoder 12 (pulled out in a straight line without being bent or folded at the wire outlet 12B) comes into contact with the pulley surface 16A1 of the pulley 16A. The pulley 16B, which is located farther from the wire encoder 12, is located at a position such that a straight line extended from the axis 14 in parallel with the initial pull-out wire 12A1 (the wire 12A pulled out straight from the wire encoder 12) and at the same distance from the base plate 18 as the initial pull-out wire 12A1 comes into contact with the pulley surface 16B1 of the pulley 16B. Then, the wire 12A passes between the pulley 16A and the pulley 16B, bends in contact with the pulley surface 16B1 of the pulley 16B, and can extend toward the measurement point.

[0053] As described above, the wire encoder 12 is attached to the framework structure 28 so as to be rotatable about the axis 14 passing through the center of gravity of the entire housing 12X of the wire encoder 12 and the accessories of the wire encoder 12 (base plate 18, two pulleys 16 (pulleys 16A, 16B) and shaft members 16A2, 16B2), i.e., the center of gravity of the measurement main body 11, and therefore can be easily rotated about the axis 14 by an external force. On the other hand, when the wire 12A is extended toward the measurement point, the tension of the wire 12A is transmitted as a pressing force to the pulley surfaces 16A1, 16B1 of the two pulleys 16 (pulleys 16A, 16B). The pressing force applied to the pulley surfaces 16A1 and 16B1 rotates the wire encoder 12 about the axis 14 as a central axis so that the wire 12A extended toward the measurement point (the portion of the wire 12A, i.e., the portion that is a straight portion of the wire 12A including the tip, may be referred to as the tip side wire 12A2) and the initial pull-out wire 12A1 become parallel. For this reason, when the wire 12A of the wire encoder 12 is extended toward the measurement point by passing between the pulleys 16A and 16B with the two pulleys 16 (pulleys 16A and 16B) disposed in the position described above, the wire encoder 12 rotates about the axis 14 as a central axis, the tip side wire 12A2 extending toward the measurement point becomes parallel to the initial pull-out wire 12A1, and the straight line obtained by extending the tip side wire 12A2 in the direction of the wire encoder 12 is perpendicular to the axis 14 (see FIG. 3). Therefore, the distance between the measurement point (a point on the guideline marked on the outer surface of the wall parapet 102 to be measured) and each axis 14 of the two wire encoders 12 can be calculated based on an electrical signal based on the pull-out length of the wire 12A output from the output section 12Y of each wire encoder 12.

[0054] Specifically, in the finished shape measuring device 10 of this first embodiment, an electrical signal based on the pull-out length of the wire 12A is wirelessly transmitted from the output section 12Y of the wire encoder 12, received by the receiving section 80 and input to the computer 82, and based on the input electrical signal, the computer 82 calculates the pull-out lengths of the wires 12A of the two wire encoders 12, and calculates the distance between the measurement point and each of the axes 14 of the two wire encoders 12.

[0055] Since the bearing mechanisms 18A provided corresponding to the two wire encoders 12 are fixed to the framework 28, the position coordinates of the axes 14 corresponding to the two wire encoders 12 are already determined, and the distance between the two axes 14 (axis distance 14X) can be calculated. Therefore, if the distance between the measurement point (a point on the guideline marked on the outer surface of the wall balustrade 102 to be measured) and the axes 14 corresponding to the two wire encoders 12 can be calculated, the position coordinates of the measurement point (a point on the guideline marked on the outer surface of the wall balustrade 102 to be measured) can be determined based on trilateration. The coordinate system at that time may be, for example, an xy coordinate system in which the longitudinal direction of the horizontal upper member 28A of the framework 28 is the x-coordinate axis and the longitudinal direction of the vertical member 28B of the framework 28 is the y-coordinate axis. This calculation based on trilateration can be executed by the computer 82.

[0056] The framework structure 28 comprises a horizontal upper member 28A, a vertical member 28B, and a horizontal lower member 28C, which are connected in a U-shape as shown in Fig. 1, and are erected on the upper surface of the deck 100. The horizontal upper member 28A and the horizontal lower member 28C are perpendicular to the vertical member 28B, so that the xy coordinate system in which the longitudinal direction of the horizontal upper member 28A of the framework structure 28 is the x-coordinate axis and the longitudinal direction of the vertical member 28B of the framework structure 28 is the y-coordinate axis becomes an orthogonal coordinate system.

[0057] A vertical caster 28C1 and a horizontal caster 28C2 are attached to the horizontal lower member 28C of the framework structure 28, and the vertical caster 28C1 moves in contact with the upper surface of the floor slab 100, and the horizontal caster 28C2 moves in contact with the side surface of the wall balustrade 102. By moving the horizontal caster 28C2 in contact with the side surface of the wall balustrade 102, the completed form measuring device 10 can be moved along the wall balustrade 102 while keeping the distance between the completed form measuring device 10 and the wall balustrade 102 constant, that is, while keeping the distance between the measurement main body 11 and the wall balustrade 102 constant.

[0058] As shown in Fig. 1, a movable body 40 is connected to the framework structure 28 via a connecting member 46. As shown in Fig. 2, one central caster 42A is attached to the movable body framework 42 of the movable body 40 on the handle 44 side, and two parallel casters 42B are attached to the opposite side of the handle 44, so that the movable body 40 is a movable body equipped with a total of three casters on the front and rear sides in the moving direction. When measuring the finished shape of the wall parapet 102, the handle 44 of the movable body 40 is grasped, and the entire finished shape measuring device 10 is moved along the wall parapet 102 and stopped in front of the portion of the wall parapet 102 to be measured, and the finished shape of the portion to be measured is measured.

[0059] As described above, the two measurement main bodies 11 are attached to the framework structure 28, the laser oscillator 26 is also attached, and the moving body 40 for movement is further connected, so that the framework structure 28 forms the whole of the finished shape measurement device 10 according to the first embodiment. Therefore, the framework structure 28 can be regarded as the device main body of the finished shape measurement device 10 according to the first embodiment.

[0060] Next, the contact measuring tool 20 of the finished shape measuring device 10 will be described.

[0061] FIG. 5 is a front view showing the contact measurement tool 20 in a schematic manner, FIG. 6 is a perspective view showing the contact measurement tool 20 in a schematic manner, and FIG.

[0062] The contact measurement tool 20 includes a contact 22 and an expandable rod 24 .

[0063] The contact 22 has an acute tip 22A, which is brought into contact with a target point (a point at which position coordinates are to be measured) on the outer surface of the concrete structure to be measured. When the tip 22A is in contact with the outer surface of the concrete structure to be measured, it is sufficient that the tip 22A is sharply pointed when viewed from a horizontal direction parallel to the outer surface, and specific shapes include, for example, a cone shape or an isosceles triangular plate shape with an acute apex angle. In the finished shape measuring device 10 according to the first embodiment, the shape of the tip 22A of the contact 22 is an isosceles triangular plate shape with an acute apex angle, as shown in Figs. 5 to 7.

[0064] The contact 22 is attached to the tip of the stretch rod 24 by a connecting bolt 22B, a mounting bracket 24A, etc. Also, a tip fitting 12C is attached to each of the tips of the two wires 12A, and as shown in Figures 5 to 7, the two tip fittings 12C are attached to the tip of the stretch rod 24 together with the contact 22 by the connecting bolt 22B, the mounting bracket 24A, etc.

[0065] 6 and 7, the mounting bracket 24A is a bent plate-like body, and the tip of the expansion rod 24 is attached to one portion 24A1. The contact 22 and the two tip fittings 12C are arranged overlappingly on the other portion 24A2 of the mounting bracket 24A, and in this state, the connecting bolt 22B passes through the other portion 24A2 of the mounting bracket 24A, the contact 22, and the two tip fittings 12C to bundle them together.

[0066] A grip portion 24B is provided at the rear end of the extendable rod 24, and during measurement, the contact measurement tool 20 is operated by gripping the grip portion 24B.

[0067] During actual measurement, an electrical signal (hereinafter sometimes referred to as a wire electrical signal) according to the pulled-out length of the wire 12A is always output wirelessly from the wire encoder 12 to the computer 82, but it is necessary to confirm the wire electrical signal when the tip 22A of the contactor 22 is abutted against a point on the guideline (a guideline marked on the outer surface of the concrete structure to be measured (here, the wall parapet 102) by the line laser light oscillated by the laser oscillator 26) which is the measurement point, and input it into the computer 82. For this reason, a measurement point confirmation button 24C is provided on the gripper 24B of the extension rod 24, and an electrical signal is output wirelessly to the computer 82 by pressing the measurement point confirmation button 24C, and the wire electrical signal from the wire encoder 12 at the moment when the electrical signal (hereinafter sometimes referred to as a confirmed electrical signal) resulting from pressing the measurement point confirmation button 24C is sent is recorded in the computer 82.

[0068] In other words, when an operator performing measurement work by holding the gripping portion 24B of the contact measurement tool 20 presses the measurement point confirmation button 24C while the tip 22A of the contactor 22 is against a point on the guideline that is the measurement point, a wire electrical signal regarding the pull-out length of the wire 12A at that measurement point (the pull-out length of each of the wires 12A from the two wire encoders 12) is recorded in the computer 82.

[0069] Then, from the wire electrical signal regarding the pull-out length of the wire 12A (the pull-out length of each of the wires 12A from the two wire encoders 12) recorded in the computer 82, the position coordinate of the measurement point (for example, the position coordinate of an xy coordinate system in which the longitudinal direction of the horizontal upper member 28A of the framework structure 28 is the x-coordinate axis and the longitudinal direction of the vertical member 28B of the framework structure 28 is the y-coordinate axis) is calculated by software in the computer 82. If the wire electrical signal regarding the pull-out length of the wire 12A (the pull-out length of each of the wires 12A from the two wire encoders 12) for all points to be measured on the guideline (all points whose position coordinates need to be determined) is recorded in the computer 82, the position coordinate of each measurement point is calculated by calculation by the software in the computer 82, and each dimension of the finished shape of the wall balustrade 102 is calculated.

[0070] Therefore, by measuring each dimension of the finished shape of the wall balustrade 102 using the finished shape measuring device 10 according to the first embodiment, the finished shape measuring work of the wall balustrade 102 can be made more efficient.

[0071] A camera 30 is attached to the vertical member 28B of the framework structure 28, but the camera 30 is not used to measure the completed shape of the parapet 102, but to record the occurrence of cracks in the parapet 102, etc., and is installed so that when measuring the completed shape of the parapet 102, the occurrence of cracks in the parapet 102, etc., can be recorded at the same time.

[0072] (1-2) Measurement procedure A procedure for using the completed shape measuring device 10 according to the first embodiment will be described below when measuring the completed shape of the wall balustrade 102. FIG.

[0073] <Step 1 (line laser light irradiation process)> First, a guideline is marked by irradiating a line laser beam from the laser oscillator 26 onto the outer surface of the concrete structure to be measured (here, the wall parapet 102). At that time, the line laser beam is irradiated so that a plane including the line laser beam is perpendicular to the outer surface of the concrete structure to be measured (here, the wall parapet 102). All of the measurement points a to g shown in FIG. 8 are points on the guideline displayed by the laser oscillator 26.

[0074] <Step 2 (recording wire length)> Next, in the line laser light irradiation step, while the tip 22A of the contact 22 of the contact measurement tool 20 is abutted against each of the measurement points a-g on the guideline displayed on the outer surface of the concrete structure to be measured (here, the wall parapet 102), the measurement point confirmation button 24C is pressed, and the wire electrical signals regarding the pull-out lengths of the wire 12A at each of the measurement points a-g (the pull-out lengths of the wire 12A from each of the two wire encoders 12) are recorded in the computer 82. In other words, for all points whose position coordinates need to be determined, the wire electrical signals regarding the pull-out lengths of the wire 12A (the pull-out lengths of the wire 12A from each of the two wire encoders 12) are recorded in the computer 82.

[0075] <Step 3 (position coordinate determination process)> From the electrical signal regarding the pull-out length of the wire 12A (the pull-out length of each of the wires 12A from the two wire encoders 12) recorded in the computer 82, the distance between each of the measurement points a-g and each of the two axes 14 is obtained, and the position coordinates of each of the measurement points a-g (for example, position coordinates in an xy coordinate system in which the longitudinal direction of the horizontal upper member 28A of the framework structure 28 is the x-coordinate axis and the longitudinal direction of the vertical member 28B of the framework structure 28 is the y-coordinate axis) are calculated by trilateration (the position coordinates of the two axes 14 are already determined, and the inter-axis distance 14X between the two axes 14 can be calculated). These various calculations are performed using software in the computer 82.

[0076] <Step 4 (dimension determination process)> Then, from the calculated position coordinates of each of the measurement points a to g, the dimensions required for managing the finished form of the wall balustrade 102 are output, for example, in the form of a list. These various calculations are performed using software in the computer 82.

[0077] (1-3) Measurement of a full-scale model of wall parapet A prototype of a finished shape measuring device having substantially the same configuration as the finished shape measuring device 10 of this first embodiment (hereinafter, this finished shape measuring device will be referred to as the prototype device) was produced, and the dimensions of a full-scale model of a wall balustrade (hereinafter, referred to as a full-scale wall balustrade model 200) were measured, while dimensional measurements were also performed using conventional methods (using only convex) for comparison.

[0078] Figures 9 to 11 are cross-sectional views (vertical cross-sectional views in the road width direction) of a full-scale wall parapet model 200 on which actual measurements were taken using the prototype device. Figure 9 is a diagram for explaining the items of data entered into the measurement software prior to measurements using the prototype device, Figure 10 is a diagram showing measurement points P1 to P6 taken using the prototype device, and Figure 11 is a diagram showing the finished dimensions h1 to h3 and w1 to w3 of the measurement target.

[0079] <Items to input to the measurement software before measurement with the prototype device> First, prior to measurements using the prototype device, a protractor was used to measure the angle between the road side wall surface 202 and the top surface 206, and the angle between the back surface 204 and the top surface 206, of the wall parapet life-size model 200, and angle A between the road side wall surface 202 and the back surface 204 was calculated and entered into the measurement software.

[0080] Also, the designed inclination angle of the road side wall surface 202 was read from the drawing and input into the measurement software.

[0081] Furthermore, the size of the chamfer 208 at the corner between the back surface 204 and the top surface 206 was measured by convex and input into the measurement software.

[0082] <Measurement using prototype device> Next, using the prototype device, position coordinates were measured for measurement points P1 to P6 shown in Fig. 10. In the measurement using the prototype device, at each of measurement points P1 to P6, measurement point confirmation button 24C was pressed with tip 22A of contactor 22 in contact with the measurement point, and wire electrical signals from two wire encoders 12 were input to the measurement software at each of measurement points P1 to P6.

[0083] Measurements using the prototype device were performed by two people, each person performing two measurements, for a total of four measurements.

[0084] <Calculating finished dimensions> After four measurements were taken using the prototype device, calculations were performed using the measurement software to calculate the height dimensions h1-h3 and width dimensions w1-w3, which are the finished dimensions of the measurement target (life-size wall balustrade model 200). The calculation results are shown in Table 1, along with the dimensional measurement results using the conventional method using only the convex and the standard values ​​for error in the finished form control criteria. In Table 1, the measurement results by the first person are shown as the first and second measurements, and the measurement results by the second person are shown as the third and fourth measurements, and the average values ​​of these four measurement results are also shown. Additionally, the measurement results using the conventional method using only the convex are shown as conventional method measurement results. Note that all values ​​in Table 1 are in mm.

[0085] [Table 1]

[0086] As can be seen from Table 1, when comparing the average values ​​of the height dimensions h1 to h3 and width dimensions w1 to w3 measured using the prototype device with the measurement results using the conventional method, the error was sufficiently small compared to the standard value of the error in the as-built control standard. In addition, the standard deviation of each of the height dimensions h1 to h3 and width dimensions w1 to w3 measured four times using the prototype device was 1.3 mm or less, and the variation in the measurement values ​​of each of the height dimensions h1 to h3 and width dimensions w1 to w3 measured four times using the prototype device was sufficiently small compared to the standard value of the error in the as-built control standard. Therefore, it is considered that the measurement of the as-built dimensions using the prototype device has a practical level of accuracy.

[0087] In the above measurement using the prototype device, the measurement was performed without consideration of keeping the inclination of the contact 22 to the horizontal plane (the inclination of the bisector of the apex angle of an isosceles triangle to the horizontal plane) constant, which may have resulted in a slightly large error. By performing the measurement while being aware of keeping the inclination of the contact 22 to the horizontal plane (the inclination of the bisector of the apex angle of an isosceles triangle to the horizontal plane) a constant value of, for example, 45°, it may be possible to further reduce the error.

[0088] (2) Second embodiment FIG. 12 is a front view showing a finished shape measuring device 60 according to the second embodiment of the present invention.

[0089] The completed shape measuring device 60 according to the second embodiment has a framework structure 62 that is significantly different from the framework structure 28 of the completed shape measuring device 10 according to the first embodiment, and the framework structure 62 of the completed shape measuring device 60 according to the second embodiment has framework members (vertical rear side members 62D) arranged up to the rear side (opposite side from the road) of the wall balustrade 102. Other than this point, the completed shape measuring device 60 according to the second embodiment is substantially the same as the completed shape measuring device 10 according to the first embodiment, so that the same reference numerals are used for the devices and members corresponding to the devices and members in the completed shape measuring device 10 according to the first embodiment, and the description thereof is omitted in principle. Note that the completed shape measuring device 60 according to the second embodiment also uses a moving body 40 like the completed shape measuring device 10 according to the first embodiment, but the moving body 40 is omitted in FIG. 12.

[0090] The framework structure 62 of the finished form measuring device 60 according to the second embodiment includes a horizontal upper member 62A, a vertical road side member 62B, a horizontal lower member 62C, and a vertical back side member 62D, and the framework members (vertical back side member 62D) are arranged up to the back side (opposite side from the road) of the wall balustrade 102, so that the framework structure 62 is arranged to surround the wall balustrade 102. In addition, two vertical casters 62C1 are attached to the horizontal lower member 62C at different distances from the wall balustrade 102, and two horizontal casters 62D1 are attached to the vertical back side member 62D at different heights. This allows the measurement work to proceed in a stable state.

[0091] Moreover, the vertical caster 62C1 moves in contact with the upper surface of the deck 100, and the horizontal caster 62D1 moves in contact with the back surface of the wall parapet 102. By moving the horizontal caster 62D1 in contact with the back surface of the wall parapet 102, it is possible to move the completed form measuring device 60 along the wall parapet 102 while keeping the distance between the completed form measuring device 60 and the wall parapet 102 constant, that is, while keeping the distance between the measurement main body 11 and the wall parapet 102 constant.

[0092] (3) Supplementary Notes on the First and Second Embodiments In both the finished shape measuring device 10 of the first embodiment and the finished shape measuring device 60 of the second embodiment, the number of wire encoders 12 (i.e., the number of measuring main bodies 11) is two, but if it is only necessary to measure the dimension in one specific direction, for example, if the top surface of the wall railing 102 is a horizontal plane and it is only necessary to measure the dimension of the top surface of the wall railing 102 in the direction perpendicular to the bridge axis, the number of wire encoders 12 (i.e., the number of measuring main bodies 11) may be one, and in this case, the measurement can be performed by pulling out the wire 12A in the direction perpendicular to the bridge axis and horizontally.

[0093] Also, the number of wire encoders 12 (i.e., the number of measurement main bodies 11) may be three or more, and multiple sets of different combinations of two wire encoders 12 may be selected from the three or more wire encoders 12, that is, multiple sets of different combinations of two measurement main bodies 11 may be selected from the three or more measurement main bodies 11, and the position coordinates of the same measurement point may be obtained for each selected set, and the multiple measurement results obtained for the position coordinates of the measurement point may be averaged to determine the position coordinates of the measurement point. In this way, it is possible to determine the position coordinates of the measurement point more accurately.

[0094] In addition, in both the finished shape measuring device 10 of the first embodiment and the finished shape measuring device 60 of the second embodiment, the wire electrical signal corresponding to the pull-out length of the wire 12A of the wire encoder 12 and the confirmation electrical signal caused by pressing the measurement point confirmation button 24C of the contact measuring tool 20 are configured to be output wirelessly to the computer 82, but both electrical signals may be configured to be output via a wired connection.

[0095] (4) Third embodiment In order to be able to simultaneously record the surface condition of the wall parapet 102, such as chipping of the concrete, changes in color and the occurrence of cracks, when measuring the completed form of the wall parapet 102, in the completed form measuring device 10 of the first embodiment, the camera 30 is attached to the vertical member 28B, and in the completed form measuring device 60 of the second embodiment, the camera 30 is attached to the vertical road side member 62B. However, in both the completed form measuring device 10 of the first embodiment and the completed form measuring device 60 of the second embodiment, the camera 30 can only photograph the occurrence of cracks in the wall parapet 102 from the road side.

[0096] In contrast, as shown in Figure 13 (front view) and Figure 14 (oblique view), the finished shape measuring device 300 of the third embodiment of the present invention is equipped with a rear-side camera 350 and a road-side camera 352 so that the crack occurrence status of the wall parapet 102A can be photographed from two directions, the road side and the rear side, and the rear-side camera 350 can be positioned on the rear side of the wall parapet 102A using an arm mechanism 324.

[0097] The completed shape measuring device 300 according to the third embodiment of the present invention will be described below. The wire encoder 12 and other devices directly used for the completed shape measurement in the completed shape measuring device 300 according to the third embodiment of the present invention are the same as those in the completed shape measuring device 10 according to the first embodiment, and the moving body 40 is also the same as those in the completed shape measuring device 10 according to the first embodiment. The same components as those in the completed shape measuring device 10 according to the first embodiment are given the same reference numerals and their explanations are omitted in principle. In this application, the back side of the concrete wall balustrade of a bridge means the side opposite to the road. In addition, in Figs. 13, 15, and 16 used to explain the completed shape measuring device 300 according to the third embodiment, a part of the wire 12A is indicated by a dashed line for convenience of illustration.

[0098] The finished product measuring device 300 of this third embodiment comprises two wire encoders 12, a contact measuring tool 20, a laser oscillator 26, a moving body 40, a framework structure 310 for the finished product measuring device, a framework structure 320 for the rear side photographing device, a road side camera holding mechanism 340, a rear side camera 350, and a road side camera 352.

[0099] The framework structure 310 for the finished shape measuring device supports two wire encoders 12 and a laser oscillator 26, similar to the framework structure 28 of the finished shape measuring device 10 of the first embodiment; however, the framework structure 310 for the finished shape measuring device is removably attached to the upper horizontal portion 42X of the movable body framework 42 of the movable body 40, as described below, and does not have casters for movement, which is different from the framework structure 28 of the finished shape measuring device 10 of the first embodiment.

[0100] The rear camera frame structure 320 includes an erect member 322 and an arm mechanism 324 .

[0101] The standing member 322 of the framework structure 320 for the rear side imaging device is detachably attached to the upper horizontal portion 42X of the movable body framework 42 of the movable body 40, and the arm mechanism 324 is rotatably attached to the standing member 322 via a hinge mechanism 330.

[0102] The arm mechanism 324 includes a rear arm member 326 , a front arm member 328 , hinge mechanisms 330 and 332 , and a counterweight 334 .

[0103] A rear end arm member 326 of the arm mechanism 324 is rotatably attached to the standing member 322 via a hinge mechanism 330 , and a front end arm member 328 is rotatably attached to the rear end arm member 326 via a hinge mechanism 332 .

[0105] The rear camera 350 photographs the rear of the wall balustrade 102A from the rear side, as shown in Fig. 13. The position of the rear camera 350 can be adjusted by an arm mechanism 324. Fig. 15 is a front view showing a state in which the tall wall balustrade 102B is photographed, and Fig. 16 is a front view showing a state in which the short wall balustrade 102C is photographed.

[0106] FIG. 17 is an enlarged perspective view of the counterweight 334. The counterweight 334 includes a plurality of detachable weight adjustment steel plates 334A, and the number of the weight adjustment steel plates 334A can be adjusted according to the weight and position of the rear camera 350. The weight adjustment steel plates 334A can be tightened and released by the lever 334B. When changing the number of the weight adjustment steel plates 334A, the lever 334B releases the tightening of the weight adjustment steel plates 334A to make the weight adjustment steel plates 334A detachable, and the weight adjustment steel plates 334A are attached and detached to adjust the number of the weight adjustment steel plates 334A. After adjusting the number of the weight adjustment steel plates 334A, the lever 334B tightens the weight adjustment steel plates 334A after the number is adjusted.

[0107] Fig. 18 is an exploded perspective view showing a state in which two support plates 342 of the road-side camera holding mechanism 340 are removed from the finished shape measurement device 300. The road-side camera holding mechanism 340 will be described with reference to Figs. 14 and 18.

[0108] The roadside camera holding mechanism 340 includes two support plates 342 and two angle members 344. The two support plates 342 are attached to the upper horizontal portion 42X of the mobile body framework 42 of the mobile body 40 so as to face each other with a predetermined gap therebetween, and the support plate 342 has a plurality of bolt holes 342A in the vertical direction for fixing the angle members 344 at a predetermined position. The angle members 344 also have a plurality of bolt holes 344A in the vertical direction, and the angle members 344 are configured so that they can be attached to the support plate 342 with bolts 346 by adjusting their vertical positions relative to the support plate 342. The portions near the lower ends of the two angle members 344 are connected to each other by a connecting member 344B, and the two angle members 344 and the connecting member 344B are substantially U-shaped. The connecting member 344B plays a role in maintaining the shape. The left and right ends of the roadside camera 352 are attached to different angle members 344.

[0109] The position of the angle iron 344 in the height direction is adjusted so that the road-side camera 352 is at an optimum position according to the shooting range of the target wall balustrade 102, and the angle iron 344 is attached and fixed to the support plate 342 with bolts 346. Figure 15 is a front view showing typically the state in which a tall wall balustrade 102B is being shot, and Figure 16 is a front view showing typically the state in which a short wall balustrade 102C is being shot.

[0110] FIG. 19 is an enlarged perspective view showing an upper horizontal portion 42X of the moving body framework 42 of the moving body 40 and its surroundings.

[0111] A bracket 310A is attached to the lower end of the framework structure 310 for the completed form measuring device, and the lower end of this bracket 310A is fixed to the upper horizontal part 42X of the movable body framework 42 of the movable body 40 by fasteners 360 as shown in Fig. 19, so that the framework structure 310 for the completed form measuring device is attached to the movable body 40. Therefore, the framework structure 310 for the completed form measuring device can be fixed to the movable body 40 by fastening the fasteners 360, and can be removed from the movable body 40 by releasing the fastening of the fasteners 360.

[0112] 19, a bracket 322A is attached to the lower end of the upright member 322 of the framework structure 320 for the rear side photographing device, and the lower end of this bracket 322A is fixed to the upper horizontal part 42X of the moving body framework 42 of the moving body 40 by a fastener 362, so that the framework structure 320 for the rear side photographing device is attached to the moving body 40. Therefore, the framework structure 320 for the rear side photographing device can be fixed to the moving body 40 by fastening the fastener 362, and can be removed from the moving body 40 by releasing the fastening of the fastener 362.

[0113] The completed form measuring device 300 of this third embodiment has both a configuration for measuring the completed form (a framework structure 310 for the completed form measuring device and a wire encoder 12, etc.) and a configuration for photographing (a framework structure 320 for the rear side photographing device, a road side camera holding mechanism 340, a rear side camera 350, and a road side camera 352), and when measuring the completed form of the wall balustrade, it is possible to simultaneously record the occurrence of cracks on the road side and rear side of the wall balustrade, but as mentioned above, the framework structure 310 for the completed form measuring device, the framework structure 320 for the rear side photographing device, and the road side camera holding mechanism 340 are all removable. Therefore, when only measuring the completed form of the wall parapet, the framework structure 320 for the rear side photographing device and the road side camera holding mechanism 340 may be removed from the completed form measuring device 300 according to the third embodiment, and only the framework structure 310 for the completed form measuring device may be used, and when only recording the crack occurrence status of the wall parapet, the framework structure 310 for the completed form measuring device may be removed, and only the framework structure 320 for the rear side photographing device and the road side camera holding mechanism 340 may be used. When recording the crack occurrence status of the wall parapet only on either the rear side or the road side, the framework structure 320 for the rear side photographing device or the road side camera holding mechanism 340 that is not used for photographing may be removed and used.

[0114] In addition, the finished shape measuring device 300 of this third embodiment is equipped with two cameras (a rear-side camera 350 and a road-side camera 352) and can record the occurrence of cracks on both sides (the road side and the rear side) of the wall parapet, but it is preferable to provide a monitor below the computer 82 (below the handle 44 of the mobile body 40) that displays images taken by the two cameras (the rear-side camera 350 and the road-side camera 352) in real time, in order to make the work easier to proceed.

[0115] Furthermore, the finished form measuring device 300 according to the third embodiment is equipped with two cameras (a rear-side camera 350 and a road-side camera 352), but one or more cameras may be added to capture images of surfaces of the wall balustrade other than the road-side surface and the rear-side surface. For example, a camera may be added to capture images of the top end of the wall balustrade from above. When a camera is added, a framework structure for adjusting the position of and supporting the added camera may also be added accordingly.

[0116] In addition, in explaining the photographing function of the completed form measuring device 300 according to the third embodiment, the explanation has been given with respect to the concrete wall balustrade of a bridge. However, the concrete structures that are photographed by the photographing function of the completed form measuring device 300 according to the third embodiment are not limited to the concrete wall balustrade of a bridge.
