  Embodiments according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. In addition, constituent elements in the following embodiments include those that can be easily replaced by those skilled in the art or those that are substantially the same.

  FIG. 1 is a schematic cross-sectional view of a composite floor slab to which a concrete compaction management device according to the present embodiment is applied.

  As shown in FIG. 1, a composite floor slab 50 to which the concrete compaction management device according to the present embodiment is applied is suitably used for a bridge floor slab, and includes a steel plate (or section steel) 51 and concrete 52. And are configured to resist the load. The steel plate 51 has a bottom steel plate 51a supported by the main beam 53 and the like, and side steel plates 51b erected on both sides of the bottom steel plate 51a. At the upper end of the side steel plate 51b, a side mold frame erected as shown by a broken line is provided. In the composite floor slab 50, a reinforcing bar 54 is disposed inside the bottom steel plate 51a and the side steel plate 51b, and concrete 52 is placed there. Concrete is also placed inside the side mold. The synthetic floor slab 50 is provided with a pavement on the concrete 52 although not shown in the figure.

  FIG. 2 is a block diagram of the concrete compaction management device according to the present embodiment. The concrete compaction management apparatus according to the present embodiment compacts concrete when the concrete 52 is compacted by the vibrator 1 when the concrete 52 is placed on the inner surface of the bottom steel plate 51a or the side steel plate 51b. Is to manage that is being done reliably. The concrete compaction management device includes the vibrator 1 and a management unit 2.

  In order to obtain high-quality concrete 52, the vibrator 1 applies fine vibration to the concrete 52 that has been struck, and removes the voids inside the concrete 52. The vibrator 1 is configured to directly insert a rod-like vibrator into the concrete 52 in order to transmit the vibration to the concrete 52. At the position of the vibrator 1, a GPS (Global Positioning System) receiver 11 as a position information detector is attached, and an insertion / extraction detection means 12 is provided.

  The GPS receiver 11 receives signals from several satellites in the sky and acquires the received position (position information of the vibrator 1). The GPS receiver 11 may be provided directly on the vibrator 1 or may be held by an operator who operates the vibrator 1. In addition, as a position information detector for acquiring position information of the vibrator 1, in addition to using GPS, for example, a light wave oscillated from a range finder toward a reflecting prism installed at a measuring point is emitted and reflected by the reflecting prism. A light-side distance finder that obtains a distance from the number of times the distance light oscillated until the distance finder senses it may be used.

  In the present embodiment, the insertion / extraction detection means 12 includes, for example, a sensor that magnetizes the steel plate 51 of the composite floor slab 50 in advance and detects the magnetic flux generated by the steel plate 51. This insertion / extraction detection means 12 approaches the steel plate 51 when the vibrator 1 is inserted into the concrete 52 and detects the magnetic flux, while being separated from the steel plate 51 when the vibrator 1 is pulled out from the concrete 52. The magnetic flux is not detected. That is, the insertion / extraction detection means 12 detects that the vibrator 1 has been inserted / removed with respect to the concrete 52. The magnetic flux detected by the insertion / extraction detection means 12 is set so that it can be detected at a position where the vibrator 1 is inserted to a depth at which the placed concrete 52 is compacted. The magnetization of the steel plate 51 includes not only magnetizing the steel plate 51 itself, but also magnetization resulting from the installation of a magnet, or magnetization that generates a magnetic field by passing a current.

  For example, a mobile computer is applied to the management unit 2. The management unit 2 includes a control unit 21, a storage unit 22, a display unit 23, a timing unit 24, a notification unit 25, and an output unit 26.

  The control means 21 is composed of a RAM, a ROM, etc., and is connected to a storage means 22 for storing programs and data. The data stored in the storage means 22 has an optimum compaction time for compacting the concrete 52. The compaction time is, for example, about 5 seconds to 15 seconds. Within this range, the setting may be changed as appropriate due to the viscosity (water content) of concrete 52, the temperature, and the weather. The data stored in the storage means 22 includes section information obtained by partitioning an area where the concrete 52 is placed within a predetermined range. As shown in the schematic plan view of the composite floor slab of FIG. 3, this section information is determined by a linear member 55 in which the area where the concrete 52 is placed in the steel plate 51 on which the reinforcing bars 54 are arranged is arranged in a lattice pattern. These positions are input to the control means 21 or obtained by arranging the GPS receiver 11 at a grid-like intersection.

  The control means 21 is connected to the GPS receiver 11. That is, the control unit 21 acquires the position information of the vibrator 1 acquired by the GPS receiver 11. Then, the control unit 21 associates the position information of the vibrator 1 acquired by the GPS receiver 11 and the section information, and acquires compaction location information that is the position of the vibrator 1 in the section information. Further, the control means 21 is connected to the insertion / extraction detection means 12. That is, the control means 21 acquires a detection signal in which the vibrator 1 is inserted into and removed from the concrete 52. The control means 21 corrects the compaction location information based on the error grasped by the GPS survey at the coordinate known point. The transmission of the position information from the GPS receiver 11 to the control means 21 and the transmission of the detection signal from the insertion / extraction detection means 12 to the control means 21 may be either wired or wireless.

  The control means 21 is connected to the display means 23. As the display means 23, for example, a display unit mounted on the mobile computer is applied. The control means 21 displays the compaction location information on the display means 23.

  Further, the control means 21 is connected to the time measuring means 24. For the time measuring means 24, for example, a timer function installed in the mobile computer or time information received by the GPS receiver 11 is used. The control means 21 performs the measurement of the compaction time and the time during which the vibrator 1 is inserted into the concrete 52 by the time measuring means 24.

  The control means 21 is connected to the notification means 25. As the notification means 25, for example, a speaker function mounted on the mobile computer or a display mechanism of the display means 23 is applied. The control means 21 notifies the fact that the compaction time has passed by the notification means 25. In addition, although the alerting | reporting means 25 may be arrange | positioned at the management part 2, the operator who operates the vibrator 1 may have.

  The control means 21 is connected to the output means 26. The output means 26 is, for example, a printing machine connected to the mobile computer by wire or wirelessly. The control means 21 outputs the information stored in the storage means 22 (the compaction result as to whether or not the concrete 52 is compacted by the vibrator 1 for the compaction time with respect to the section information) by the output means 26.

  Control of the concrete compaction management device by the control means 21 described above will be described. FIG. 4 is a flowchart of the concrete compaction management apparatus according to the present embodiment. Here, it is assumed that the operator operates the vibrator 1 and the work manager has the management unit 2.

  First, the control means 21 associates the position information of the vibrator 1 acquired by the GPS receiver 11 and the section information, acquires the compaction location information that is the position of the vibrator 1 in the section information, and performs the compaction. The location information is displayed on the display means 23 (step S1). For example, as shown in the figure showing an example of the display of the concrete compaction management device in FIG. 5, the display means 23 vibrates with coordinates ☆ in the coordinates [x2, y2] as the section information as compaction location information. The position information of the machine 1 is displayed. As shown in FIG. 5, the display means 23 displays the display of the coordinates, the date and time of compaction work, and a preset compaction time. Further, the display means 23 can enlarge or reduce the compaction location information or scroll the information.

  Next, when the detection signal inserted into the concrete 52 by the vibrator 1 is input from the insertion / extraction detection means 12 (step S2: Yes), the control means 21 starts measuring time by the time measuring means 24 and The compaction location information is stored in the storage means 22 (step S3). At this time, the display means 23 displays the elapsed time as shown in FIG.

  Next, when the compaction time has elapsed in the measurement by the time measuring unit 24 (step S4: Yes), the control unit 21 notifies the progress of the compaction time by the notification unit 25 (step S5).

  Next, when the detection signal with which the vibrator 1 is pulled out from the concrete 52 is input from the insertion / extraction detection means 12 (step S6: Yes), the control means 21 inputs the detection signal with which the vibration machine 1 is inserted into the concrete 52. The elapsed time from when the vibrator 1 is inserted into the concrete 52 until it is pulled out, and the compaction time at that time, are associated with the compaction location information including the positional information at the time and stored in the storage means 22 (step S7) This control is terminated. The information stored in the storage means 22 can be displayed on the display means 23. For example, as shown in FIG. 6, as the compaction place information, the coordinates [x2, y2] as the section information are In addition to displaying the position information of the vibrator 1 with a mark, the display of the coordinates, the date and time of compaction work, a preset compaction time, and an elapsed time are displayed.

  Further, information (consolidation location information and compaction time) stored in the storage means 22 is output by the output means 26 at the time of compaction work or on the day after the compaction work.

  FIG. 7 is a diagram illustrating an example of output by the output unit. As shown in FIG. 7, the output by the output means 26 is, for example, as shown in FIG. 6, in the coordinates [y1 to yX, x1 to xX] as the division information, the vibrator 1 The movement locus is displayed as the position information, and the fact that the concrete 52 is compacted by the vibrator 1 in the compaction time is indicated by color coding.

  In step S2, the control means 21 waits for input of the detection signal until the vibrator 1 inputs the detection signal inserted into the concrete 52 (step S2: No). In step S4, the control means 21 continues to measure time until the compaction time has elapsed (step S4: No). Further, in step S6, the control means 21 continues the notification until the vibrator 1 inputs the detection signal extracted from the concrete 52 (step S6: No).

  As described above, the concrete compaction management apparatus according to the present embodiment includes the GPS receiver 11 serving as the position information detector provided at the position of the vibrator 1 that compacts the concrete 52, and the region where the concrete 52 is placed. The display unit 23 for displaying the section information partitioned in a predetermined range and the compaction location information associated with the position information of the vibrator 1 acquired by the GPS receiver 11, and the vibrator 1 is inserted into and removed from the concrete 52. An insertion / extraction detection means 12 for detecting this, a timing means 24 for starting time measurement when the insertion / extraction detection means 12 detects that the vibrator 1 has been inserted into the concrete 52, and a predetermined compaction required for compaction. When the time is measured by the time measuring means 24, the notifying means 25 for notifying that the compaction time has elapsed, and the vibrator 1 is pulled out from the concrete 52. When the insertion / extraction detecting means 12 detects that the passage is stored, the compaction location information is stored in association with the elapsed time from when the vibrator 1 is inserted into the concrete 52 until it is pulled out and the compaction time. 22.

  According to this concrete compaction management device, since the vibrator 1 is detected to be inserted into and removed from the concrete 52, it is possible to reliably compact the concrete. In addition, since the record of the position where the concrete 52 is compacted and the record of the compaction time remain, the compaction work can be managed. Moreover, since the elapse of the compaction time after the vibrator 1 is inserted into the concrete 52 is notified, the compaction time can be managed automatically. As a result, it is possible to manage that the concrete 52 is compacted reliably.

  Moreover, the concrete compaction management apparatus of this Embodiment can acquire the positional information on the vibrator 1 exactly by using the GPS receiver 11 as a positional information detector.

  Further, the concrete compaction management device of the present embodiment is applied when placing concrete on the steel plate 51 (including the bottom steel plate 51a and the side steel plate 51b) of the composite floor slab 50. Detects the magnetic flux in which the steel plate 51 is magnetized.

  According to this concrete compaction management device, since the vibration 1 is detected by the vertical movement of the vibrator 1 by detecting the magnetic flux, the insertion and removal of the vibrator 1 with respect to the concrete 52 is ensured. Can be detected.

  Moreover, the concrete compaction management apparatus of this Embodiment is restricted to the composite floor slab 50, as shown in the figure which shows the other example of the insertion / extraction detection means of the concrete compaction management apparatus which concerns on this Embodiment of FIG. Instead, the magnetic flux of the magnet (permanent magnet or electromagnet) 58 installed outside the formwork 57 on which the concrete 52 is placed may be detected.

  Also in this concrete compaction management device, it is detected by the vertical movement of the vibrator 1 that the vibrator 1 has been inserted into and removed from the concrete 52 by detecting the magnetic flux, so that the insertion and removal of the vibrator 1 into the concrete 52 is ensured. It becomes possible to detect.

  Further, although the concrete compaction management device of the present embodiment is not clearly shown in the drawing, the insertion / extraction detection means 12 may detect contact or non-contact of the vibrator 1 with respect to the concrete 52. As the insertion / extraction detection means 12 for detecting contact or non-contact of the vibrator 1 with the concrete 52, for example, a sensor for detecting a change in capacitance is provided.

  According to the concrete compaction management device, the state in which the vibrator 1 is inserted into and removed from the concrete 52 is directly detected, so that the concrete 52 can be reliably compacted.

  Further, the concrete compaction management apparatus of the present embodiment includes an output unit 26 that outputs information stored in the storage unit 22.

  According to the concrete compaction management device, it is possible to confirm the compaction work and management records at the time of compaction work or on the day after the compaction work.

  Further, in the concrete compaction management apparatus of the present embodiment, the information output to the output means 26 is compaction as to whether or not the concrete 52 is compacted by the vibrator 1 with the compaction time with respect to the section information. It is a result.

  According to this concrete compaction management device, the position at which the vibrator 1 is inserted into and removed from the concrete 52 and the elapsed time from when the vibrator 1 is inserted into the concrete 52 to the time it is pulled out are compacted with respect to the section information. It becomes possible to confirm at a glance whether or not the compaction result is over time.

  Further, the concrete compaction management method of the present embodiment includes a step of acquiring the position of the vibrator 1 for compacting the concrete 52 by the GPS receiver 11 as a position information detector, and then the vibrator 1 is concrete. When the insertion / removal detection means 12 detects that the insertion has been performed on 52, the step of measuring the time and then the compaction time has elapsed when a predetermined compaction time required for compaction is measured When the insertion / extraction detecting means 12 detects that the vibrator 1 has been pulled out from the concrete 52, the vibrator 1 with respect to the compaction place information that is the position of the vibrator 1 is detected. Storing in the storage means 22 the elapsed time from when the sheet is inserted into the concrete 52 until it is pulled out and the compaction time in association with each other.

  According to this concrete compaction management method, since the vibrator 1 is detected to be inserted into and removed from the concrete 52, it is possible to reliably compact the concrete. In addition, since the record of the position where the concrete 52 is compacted and the record of the compaction time remain, the compaction work can be managed. Moreover, since the elapse of the compaction time after the vibrator 1 is inserted into the concrete 52 is notified, the compaction time can be managed automatically. As a result, it is possible to manage that the concrete 52 is compacted reliably.

  In addition, the concrete compaction management method of the present embodiment further includes a step of outputting the information stored in the storage unit 22 to the output unit 26.

  According to this concrete compaction management method, it is possible to check the compaction work and management records at the time of compaction work or on the day after the compaction work.

  In addition, the concrete slab of the present embodiment is managed by a management record that associates the position of the vibrator 1 that compacts the concrete 52 with the compaction time during which the concrete 52 is compacted by the vibrator 1. Specifically, the position of the vibrator 1 that compacts the concrete 52 is acquired by the GPS receiver 11 as a position information detector, and the insertion / extraction detection means 12 indicates that the vibrator 1 has been inserted into the concrete 52. After the predetermined compaction time required for compaction has been detected, it has been detected by the insertion / extraction detection means 12 that the vibrator 1 has been pulled out from the concrete 52, and the compaction location information, which is the position of the vibrator 1, is detected. Then, the elapsed time from the time when the vibrator 1 is inserted into the concrete 52 to the time when it is pulled out and the compaction time are stored in the storage means 22 in association with each other.

  According to this concrete slab, since the record of the position where the concrete 52 is compacted and the record of the compaction time remain, the compaction work can be easily managed.

  In addition, although the concrete compaction management apparatus mentioned above showed the case where the vibration machine 1 was one, it can be applied even when the vibration machine 1 is used with two or more. When a plurality of vibrators 1 are used, the compaction location information, compaction time, and elapsed time of each vibrator 1 are managed and displayed or notified.

  In the concrete compaction management device of the present embodiment, the composite floor slab 50 of the bridge is taken as an example as a target concrete structure, but this is not the only case, and the concrete structure in general that requires compaction. Applicable.

  In addition, as shown in the figure which shows the other example of the insertion / extraction detection means of FIG. 9, the insertion / extraction detection means 12 is two transmitters 59a arrange | positioned in the position where the length direction (height direction) of the vibrator 1 differs. , 59b and a receiver 59c that receives signals from the transmitters 59a, 59b. The transmitters 59a and 59b transmit ultrasonic waves, light, or radio waves. One transmitter 59a is provided at a position where the transmitter 59a is inserted into the concrete 52 of the vibrator 1, and the other transmitter 59b is used for the vibrator 1. It is provided at a position where it is not inserted into the concrete 52. The receiver 59c corresponds to the transmitters 59a and 59b and transmits ultrasonic waves, light, or radio waves. Then, in FIG. 9A, when the signal from each transmitter 59a, 59b is not received by the receiver 59c, it is detected as a dormant state in which the concrete 52 is not compacted, and FIG. 9B, when the signals from the transmitters 59a and 59b are received by the receiver 59c, it is detected that the compacting operation has been started and the vibrator 1 has been pulled out of the concrete 52, as shown in FIG. 9B. In addition, when the signal from one transmitter 59a is not received by the receiver 59c and the signal from the other transmitter 59b is received by the receiver 59c, the signal from one transmitter 59a is blocked by the concrete 52. As a result, the compacting operation is started and it is detected that the vibrator 1 is inserted into the concrete 52. In this way, the insertion / extraction detection means 12 shown in FIG. 9 also detects the state in which the vibrator 1 is inserted into and extracted from the concrete 52. Can be reliably performed.

  Moreover, the insertion / extraction detection means 12 used the distance measuring device 60 which is arrange | positioned at the vibrator 1 and detects the distance from the upper surface of the concrete 52, as shown in the figure which shows the other example of the insertion / extraction detection means of FIG. It may be a thing. For example, a laser distance meter is applied to the distance measuring device 60 and is provided at a position where the distance measuring device 60 is not inserted into the concrete 52 of the vibrator 1. 10A, the distance L from the upper surface of the concrete 52 measured by the distance measuring device 60 is the distance Lo (preliminarily controlling means from the distance measuring device 60 to the insertion end of the vibrator 1). Is set to 21) and is detected as a resting state in which the concrete 52 is not compacted. Thereafter, as shown in FIG. 10B, when the distance L from the upper surface of the concrete 52 measured by the distance measuring device 60 is shorter than the distance Lo, the compacting operation is started and the vibrator 1 is moved to the concrete. It is detected that it has been inserted into 52. Thereafter, as shown in FIG. 10A, when the distance L from the upper surface of the concrete 52 measured by the distance measuring device 60 becomes longer than the distance Lo again, the compacting operation is started and the vibrator is started. It is detected that 1 is pulled out from the concrete 52. Further, in the compacting operation, the depth Ls of the concrete 52 to be placed is set in the control means 21 in advance, so that the range of (Lo−L) <Ls is established, so that the vibrator 1 can have the floor slab. It is possible to manage the amount of insertion (insertion depth) of the vibrator 1 so as not to touch. Thus, like the insertion / extraction detection means 12 shown in FIG. 10, a change in the distance from the top surface of the concrete 52 when the vibrator 1 moves is detected, and the vibrator 1 is inserted into and removed from the concrete 52. Even if the vibration is detected, the state in which the vibrator 1 is inserted into and removed from the concrete 52 is detected, so that the insertion and removal of the vibrator 1 from the concrete 52 can be reliably detected even in the case of the steel plate 51 and the formwork 57. Therefore, the concrete 52 can be reliably compacted.
