  The present invention relates to a wall surface investigation system for investigating a deterioration state of a wall surface.

  Due to deterioration over time, damage to the wall surface of the building, such as cracks, floating or falling off of the sealing material, discoloration or discoloration or contamination of the surface coating material, erosion (weathering), etc. may occur. In addition, in a building with a tiled outer wall or a mortared outer wall, even if no change in appearance is observed, there is a risk that the surface material will rise from the concrete frame and fall due to the occurrence of an earthquake or the like. In buildings, etc., therefore, the deterioration of the wall surface is regularly examined.

  In the wall survey method for buildings, etc., in the case of middle-rise or high-rise buildings, the investigator is usually mounted on a gondola that can be moved vertically and horizontally along the wall surface. A hitting investigation was performed in which a wall was hit with a test hammer to hear the hitting sound (see, for example, Patent Document 1 and Patent Document 2). In the wall surface investigation method for buildings and the like, a method for conducting a wall surface investigation with higher accuracy by mechanically discriminating the impact sound with respect to a reference value when the impact sound is investigated (for example, Patent Document 3). See). Patent Document 4 discloses a wall surface survey method for a building or the like using a surveying device that is mounted on a wall surface of a surveyed building and is remotely operated by mounting a striking means for striking the wall surface or a microphone that collects sound of the impact. It is disclosed.

The survey terminal 2 is connected to the weight unit 11 by a cable 22 having a power line and a signal line, for example, the survey machine main body 9 and further connected to the terminal computer 3 via the weight unit 11 by a signal cable 23. The Note that the survey terminal 2 is also connected to the terminal computer 3 via a signal cable (not shown).

  The survey terminal 2 is configured such that the survey point area of the wall surface 8A on which the survey machine main body 9 is suspended by the remote control of the electric winch of the suspension unit 10 via the terminal computer 3 by the surveyor (operator) P. It is moved up and down at a predetermined speed in the height direction, performs batting investigation and imaging on a wall surface 8A described later, and outputs investigation data and image data to the terminal computer 3. For example, the survey terminal 2 continuously captures images of the wall surface 8 </ b> A by the CCD camera 19 and performs a hit survey at every predetermined point. When the survey terminal 2 completes the survey of the predetermined survey point area on the wall surface 8A, the suspension unit 10 is moved along the roof top, so that the survey machine body 9 moves to the corresponding area of the next survey point. Is done. Similarly, in the survey point area, the survey terminal 2 moves the survey machine main body 9 up and down along the wall surface 8A and performs a predetermined survey.

  The survey terminal 2 receives a control signal output from the terminal computer 3 side as necessary to the survey machine main body 9 via the cable 22 to the control unit 13, and power via the weight unit 11. Power is supplied to the unit 14. The investigation terminal 2 outputs a drive signal from the control unit 13 to the power unit 14 based on the control signal, so that the electric motor is driven, and an impact investigation is performed in which the test hammer 17 strikes the wall surface 8A. In the investigation terminal 2, the striking operation by the test hammer 17 may be a striking investigation in which a rubbing sound is generated by rubbing the wall surface 8A.

  In the survey terminal 2, the survey machine main body 9 has a microphone 18 installed in the chassis 12 in the vicinity of the test hammer 17, and the impact sound generated by the test hammer 17 is collected by the microphone 18 and input. This is supplied to the output control unit 15. The investigation machine main body 9 images the wall surface 8 </ b> A by the CCD camera 19 based on the drive signal from the control unit 13. In the investigation machine main body 9, as described above, the wall surface 8A is continuously imaged by the CCD camera 19, and the moving operation and the investigation operation are remotely performed while the wall image is confirmed by the operator P. For example, when an abnormality is detected on the wall surface 8 </ b> A in the hitting investigation by the test hammer 17, the CCD camera 19 may enlarge the portion and take an image.

  The investigation machine main body 9 outputs the impact sound signal collected by the microphone 18 and the wall surface image data captured by the CCD camera 19 to the terminal computer 3 side via the input / output control unit 15. In the investigation machine main body 9, the distance counter unit 16 is configured by, for example, an encoder provided in the shaft portion of the wheel 20, detects the rotation amount of the wheel 20, and outputs it to the input / output control unit 15.

Data or diagnostic data described later is stored in the storage unit. The terminal computer 3 has a recording / reproducing unit of a recording medium such as a CD (compact disc), for example, thereby reproducing the CD storing the reference hitting sound data and reading it into the internal hard disk (storing unit), or the hitting sound signal. Alternatively, the wall surface image data may be read from the recording unit and recorded on the CD.

  In the wall hitting investigation, a normal state wall is hit with a test hammer in advance and a spectrum of the hitting sound is obtained and stored as reference hitting sound data. The reference hammering sound data and the wall 8A of the investigation handling building 8 are used as the test hammer 17. Compared with the sound data of the impact sound obtained by striking. In the wall hitting investigation, as disclosed in the above-described patent document, when the wall surface 8A has a defect such as a floating surface material, a crack, a defect, or an explosion, the investigation hit is performed on the reference hitting sound data. Each sound data has its own spectrum. In the wall surface hitting investigation, it is possible to diagnose the content of faults caused by the wall surface 8A and the extent thereof, depending on the state of the spectrum difference.

  In the wall impact survey, the reference impact sound data and the diagnostic criteria are different depending on the types of surface materials such as tiles and mortar provided on the surface of the concrete frame. Therefore, when the terminal computer 3 carries out the survey to reduce the capacity load, the reference hitting sound data and the like conforming to the specifications of the surveyed building 8 are created in advance, for example, a recording medium on which this is recorded is loaded. Read into the internal hard disk that constitutes the storage unit.

  The terminal computer 3 is supplied with impact sound data collected by the microphone 18 from the survey terminal 2 and wall surface image data captured by the CCD camera 19 every moment. The terminal computer 3 displays the control screen shown in FIG. 3 on the monitor 24 so that the operator P can check the condition of the wall surface and perform a predetermined control operation on the control screen. The terminal computer 3 is provided with a wall surface image display unit 24A and a diagnostic data display unit 24B on the control screen 24 of the monitor 24 as shown in FIG. Thus, a control unit 24C constituting the survey terminal control unit is provided.

  The terminal computer 3 monitors the state of the wall surface 8A displayed on the wall surface image display unit 24A by the operator P, and instructs the stop / return operation of the investigation machine main body 9 as necessary to confirm the details of the defective part. In addition, it is possible to perform a recording operation and the like. The terminal computer 3 compares the hitting sound data output from the survey terminal 2 with the reference hitting sound data stored in the storage unit to create predetermined diagnostic data, and displays it on the diagnostic data display unit 24B of the monitor 24. And store it in the storage unit. For example, the terminal computer 3 diagnoses the degree by classifying it into the floating state of the surface material at each investigation point, the presence or absence of cracks, the presence or absence of defects, the presence or absence of explosions, and the like.

  The terminal computer 3 performs a predetermined control operation by clicking the command icon displayed on the control unit 24C of the control screen 24. On the control screen 24, as shown in FIG. 3, as a command icon, a start position icon for setting the reference position of the survey, an end icon for supporting the end of the survey, an up / down icon for moving the survey machine body 9 up and down, or a survey machine body 9 is provided with a scan icon, an input completion icon, a recheck icon, etc. for instructing a batting survey.

  As described above, the terminal computer 3 is connected to the survey terminal 2 via the cable 22 and the signal cable 23 to exchange control signals and survey result data. However, the terminal computer 3 is not limited to this configuration. . Of course, the terminal computer 3 may be wirelessly connected to the survey terminal 2 by a short-range wireless system such as a Bluetooth wireless system to perform signal exchange.

  In the wall surface survey system 1, after completing a predetermined wall surface survey for the survey target building 8, the survey result data and wall surface image data which are raw information stored in the storage unit are sucked up from the terminal computer 3 brought back from the survey site. For example, a process of storing in a storage medium such as a CD is performed. In the wall surface survey system 1, the terminal computer 3 is connected to the management computer 4 that is a host computer, and the survey result data and diagnostic data stored in the storage unit created by the terminal computer 3 are supplied to the management computer 4.

It also has a database function for saving. In the wall surface survey system 1, upon conducting the survey, the requester receives provision of building drawing information 26 such as design drawings related to the surveyed building 8 shown in FIG. Based on the building drawing information 26, the management computer 4 receives building white drawing data such as dimension values of each part. The management computer 4 creates CAD (Computer Aided Desin) data based on the building white drawing data and stores it in the storage unit.

  In the wall surface survey system 1, a specific method for performing a wall surface survey to be performed on the survey target building 8 is examined based on the building drawing information 26, and a survey point for performing a hit survey is determined by the survey terminal 2. . In the wall surface survey system 1, the specific survey contents (interval and number of hits surveys, etc.) differ depending on the building shape and wall surface specifications. Therefore, as shown in FIG. For example, the respective reference points a1 and a2 are determined for the residential block and the tower block part having different shapes in the horizontal direction from the position.

  In the wall surface survey system 1, the first survey point p1 to the fourth survey point p4 at which the batting survey by the survey terminal 2 is actually performed at a predetermined interval from the reference points a1 and a2 are determined. In the wall surface survey system 1, the start positions f1 to f4 of the batting survey by the survey terminal 2 are also determined at the survey points p1 to p4, respectively.

  In the wall surface survey system 1, the above-described survey execution point data is input to the management computer 4 and subjected to predetermined data processing. The management computer 4 performs synthesis processing of the survey execution point data and the building drawing information 26 described above, and creates CAD data and stores it in the storage unit. Further, the management computer 4 reads the survey execution point data from the storage unit at the time of performing the survey, and stores it in the storage unit of the terminal computer 3 brought into the survey site.

  When the management computer 4 ends the field survey and is supplied with the survey result data and diagnostic data of the surveyed building 8 from the terminal computer 3, the management computer 4 further performs predetermined data processing on the survey result data and diagnostic data. Diagnosis result chart data for creating a predetermined survey result data table 6 in accordance with the report format is created. Further, the management computer 4 reads out the CAD data stored from the storage unit, performs synthesis processing with the diagnostic data, and creates diagnostic result synthesized building drawing data for creating the diagnostic result synthesized building drawing 7. Note that the management computer 4 creates a storage medium such as a CD that stores charts and the like adapted to the report format as necessary.

That is, the abnormality occurrence part tabulation list 6A shows, in a list form, abnormal states that have occurred at the investigation position in the height direction from the investigation start position at the investigation point A. Also, the tabulation result table 6B shown in FIG. 6B is a tabulation sheet that tabulates and displays the status of the abnormality occurrence part for each of the survey points p1 to p4. As a result, the survey point A is 4.50%. It is concluded that the tiles are floating.

  The diagnosis result composite building drawing 7 shown in FIG. 6 is a view showing the appearance of the abnormality occurrence portion and the contents thereof for each of the survey points p1 to p4 with respect to the external view of the survey target building 8. . That is, in the diagnosis result composite building drawing 7, the positions of the survey points p1 to p4 in the survey target building 8 are specifically displayed, and the presence / absence of an abnormality occurrence portion at each survey position of each of the survey points p1 to p4. The contents are identified and illustrated in a band shape. In addition, although the detail is abbreviate | omitted, the diagnostic result synthetic | combination building drawing 7 is output by the color display which classified the abnormality occurrence part and the content into each color for every investigation point p1-p4.

  In the wall surface survey system 1, the above-described survey result data table 6 makes it possible to grasp in detail the occurrence status and contents of the abnormality occurrence portion at each of the survey points p1 to p4, mainly using numerical data. Further, in the wall surface survey system 1, anyone can easily check the wall surface state of the building to be surveyed 8 by simultaneously displaying the building appearance, the occurrence state of the abnormality occurrence portion, and the contents thereof on the diagnosis result composite building drawing 7.

(Step H-3). In the report creation process H, a storage medium such as a CD that stores charts and the like adapted to the report format is created (step H-4).

  In the process of creating the diagnosis result composite building drawing data, the first survey point p1 to the fourth survey point p4 and these survey points p1 to p1 are positioned in the drawing data with respect to the origin Gp and the reference points a1 and a2 as described above. Position information such as the start positions f1 to f4 of the hit survey at p4 is input. In the process of creating the diagnosis result composite building drawing data, the position of each of the survey points p1 to p4 is specified and the process of assigning the name is performed based on the position information output from the terminal computer 3.

  In the process of creating the diagnosis result composite building drawing data, data processing for associating the investigation result data and the diagnosis data with the corresponding positions of the investigation points p1 to p4 specified in the drawing data is performed. In the process of creating the diagnosis result composite building drawing data, a process of adding a term processing or a symbol processing for illustration to the contents of each diagnosis data is performed on the drawing data. In the process of creating the diagnosis result composite building drawing data, when there is drawing data relating to a plurality of building drawings, the same data processing is performed on each drawing data.

  In the report creation process H, the printer 5 is instructed to output the survey result data table 6 in a predetermined format by instructing the printer 5 to output the survey result data table 6 from the management computer 4 based on the diagnosis result chart data. 6 is printed out (step H-5). In the report creation process H, the printer 5 instructs the printer 5 to output the diagnosis result composite building drawing 7 based on the diagnosis result composite building drawing data from the management computer 4, so that the printer 5 draws the drawing of the surveyed building 8. The diagnosis result composite building drawing 7 displayed by combining the diagnosis results is printed out (step H-6).
