Description

  The present invention relates to a multifunctional building survey apparatus for investigating the state of a buried object such as a reinforcing bar embedded in a concrete frame as well as a deterioration state of a wall surface.

  For buildings, in general, investigation of wall surface deterioration over time has been carried out in order to make a renovation plan, etc., but surveys of buried objects embedded in concrete enclosures such as reinforcing bars or various pipes, so-called skeleton surveys, are also conducted. Done. 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.

  For wall surveys of buildings, etc., in the case of medium-rise or high-rise buildings, the investigator usually gets on a gondola that can be moved vertically and horizontally along the wall surface. A hit survey was conducted in which a test hammer was struck to hear the hitting sound. In the wall surface survey of buildings and the like, a method of conducting a highly accurate wall surface survey by comparing the impact sound with a reference value has been proposed (for example, see Patent Document 1). Patent Document 2 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 hitting means for striking a wall surface or a microphone that collects a sound of impact. It is disclosed.

  On the other hand, the investigation of buried objects such as buildings has been conducted for the purpose of confirming the position of existing piping and reinforcing bars in advance when there are no structural drawings when replacing water supply and drainage pipes. As a result, there are many cases in which re-confirmation of seismic strength such as reinforcing bar arrangement, reinforcing bar specifications, concrete cover thickness, etc. has been performed. For investigating buried objects such as buildings, for example, a method of irradiating X-rays from the surface side of a wall surface, a method of irradiating ultrasonic waves (for example, see Patent Document 3), or a method of irradiating electromagnetic waves (for example, Patent Documents) The so-called nondestructive investigation method is adopted.

  Patent Document 5 discloses an outer wall diagnostic apparatus in which various sensors and a printing machine are mounted on a gondola that moves along a wall surface in order to perform diagnosis of an existing outer wall in an outer wall renovation work without using a scaffold. The outer wall diagnostic apparatus investigates the state of internal reinforcing bars as well as the degree of unevenness of the wall surface, cracks, presence or absence of peeling, etc. by various sensors, and marks a defective portion with a printing machine if necessary.

JP 2000-131288 A Japanese Utility Model Publication No. 7-34367 JP 2003-149214 A JP 2003-90806 A Japanese Patent Laid-Open No. 7-224544

  By the way, in the conventional wall survey of buildings, etc., when a large-scale gondola is installed just for surveying the surveyed building, the survey cost becomes extremely large, for example, the number of residents is relatively small. In other apartments, etc., there was a problem that the cost burden was extremely large and it was difficult to implement. In the wall surface surveying method for buildings and the like disclosed in Patent Document 1, a survey must be conducted by installing a gondola in the surveyed building in the same manner, and highly accurate survey result data can be obtained. For example, it has been difficult for amateurs such as condominium residents to directly evaluate the survey results.

  The wall surface investigation method for buildings and the like disclosed in Patent Document 2 does not require installation of a large-scale gondola or the like, and can carry out a highly accurate investigation while reducing the burden of investigation costs. However, in this wall survey method for buildings, etc., as with the other conventional wall survey methods described above, how much trouble the condominium residents, etc. have in any part of the target building from all the data obtained from the survey machine There was no provision of an evaluation result that could directly confirm whether or not

  In the conventional wall survey device, when a large-scale gondola was not used, the survey terminal was suspended up and down along the wall surface by a suspension machine installed in the surveyed building, and obtained with the survey terminal. The survey data is configured to be supplied to the terminal computer through a signal cable. In the conventional simplified wall surface survey device described above, the weight of the signal cable and power cable is added to the suspension machine along with the weight of the survey terminal, so the survey terminal is suspended by a large-diameter wire with high strength. For this reason, it was used exclusively for relatively low-rise buildings.

  In the conventional wall surface survey device, as described above, the survey terminal is shaken due to the influence of wind, the resistance of the suspension wire, etc. For this reason, there was a problem that the survey accuracy was lowered. In addition, in the conventional wall surface inspection device, a weight box having a weight mechanism that pushes out and winds the signal cable and the power cable on the ground and presses the inspection terminal device against the wall surface corresponding to the suspension machine is installed. . In the conventional wall surface survey device, the survey could not be performed when the installation space for the weight box could not be secured around the target building. In the conventional wall surface inspection device, for example, there is a possibility that the inspection terminal descends at an abnormal speed due to the detachment of the hanging wire from the guide reel, breakage or slipping of the drive shaft, and the investigation terminal is operated on the ground. Sufficient attention was required to ensure the safety of investigators.

  On the other hand, the investigation of buried objects such as buildings does not have a concept of regular implementation like the above-described wall survey, and is conducted at a time necessary as an original investigation. Conventional investigation of buried objects such as buildings requires a large-scale X-ray irradiation device, ultrasonic irradiation device, or electromagnetic wave irradiation device, and requires a large amount of investigation cost due to the installation of a scaffold or the like. Therefore, even when the client makes a comprehensive repair plan based on the survey results of the buried object survey and the wall surface survey, for example, the client is forced to pay for each survey cost and inconvenience during the survey period.

  Therefore, the present invention eliminates the problems of the conventional building survey device described above, improves safety with a simpler configuration, and moves up and down along the wall surface in a stable state so that the survey terminal is stable and precise. The present invention has been proposed for the purpose of providing a building survey apparatus that enables various building surveys to be performed while reducing costs.

Based on the control instruction signal, the self-propelled lifting mechanism is transmitted to the hanging wire and moved up and down along the wall surface of the building under investigation, while the investigation section investigates the deterioration of the wall surface and the buried object in the concrete enclosure. Is output to the terminal computer.

  In the investigation terminal, the terminal control circuit unit outputs a control signal for controlling the operation to each component unit based on the control instruction signal transmitted from the terminal computer received by the first wireless unit.

  In the survey terminal, the data processing unit includes a data processing unit that processes the survey information surveyed by each survey unit of the survey unit to create predetermined survey data, and a memory unit that temporarily accumulates the survey data. In the survey terminal, the position data generation unit detects the position on the wall surface of the survey target building, generates position data, and outputs the position data to the data processing unit via the terminal control circuit unit. In the investigation terminal, the self-propelled lifting mechanism has a plurality of geared drive pulleys and tension pulleys that entangle the suspension wire fed from the suspension mobile device, and a control transmitted from the terminal computer received by the first wireless unit. A drive motor that drives at least one of the geared drive pulleys based on the instruction signal, and is moved up and down from the survey start position to the predetermined position along the wall surface along the hanging wire. To do. In the survey terminal, the first wireless unit exchanges control instruction signals and survey data with the second wireless unit of the terminal computer.

  The building survey apparatus is a control in which a terminal computer outputs a predetermined control instruction signal to each component based on an input operation unit for performing an operation for inputting an investigation instruction by an operator and an output signal output from the input operation unit.

In the building survey apparatus, the survey terminal is driven based on a control instruction signal transmitted from a terminal computer based on an operator's operation input, and is set to a reference position where surveying is started. In the building survey apparatus, the self-propelled lifting mechanism is driven based on the control instruction signal transmitted from the terminal computer, and the survey terminal moves up and down along the wall surface from the reference position. In the building survey device, an excessive load was applied by, for example, the cell lock wire being unwound at an abnormal speed due to detachment of the suspension wire from the pulley or the survey terminal being lifted from the wall by being blown by the wind. In some cases, the cell lock mechanism operates to lock the cell lock wire, thereby holding the survey terminal and improving safety.

  In the building survey apparatus, position data is transmitted from the survey terminal to the terminal computer, and the operator remotely operates the survey terminal based on the position data. In the building survey device, the survey terminal investigates the deterioration state of the wall surface and the reinforcing bar arrangement in the concrete frame while the survey terminal moves up and down to a predetermined position by the self-propelled lifting mechanism. The inspection terminal performs an operation of generating inspection sound by striking or rubbing the wall surface by the inspection sound generating means, and the sound collecting means collects the inspection sound. The investigation terminal images an image of a predetermined portion of the wall surface with an imaging unit based on an instruction from the terminal computer as necessary. The survey terminal investigates a buried object such as the presence / absence of a reinforcing bar in a concrete frame at a predetermined location on the wall surface, a bar arrangement state, a concrete cover thickness, or an existing pipe by a buried object searching means.

  In the building survey device, the survey terminal uses the data processing unit to survey data based on the survey information obtained from each survey unit of the survey unit described above by the data processing unit and the position data from the position data generation unit. Create The survey terminal transmits this survey data to the terminal computer via the first wireless unit and temporarily stores it in the memory means. The survey terminal transmits to the terminal computer the image data of the wall surface imaged by the imaging means and the survey data investigated by the buried object searching means.

A reinforcing bar state image or the like in the concrete frame is displayed so that the operator can confirm this image. In the building survey device, when it is detected that the survey terminal has moved to a predetermined position based on the position data, a control signal is output from the control circuit unit to each unit by the operator's input operation, and the survey end process is performed. Done.

  In the building survey device, when the survey of the predetermined area is completed, a control instruction signal is transmitted from the terminal computer side. Based on this control instruction signal, the survey terminal performs a lifting operation by the self-propelled lifting mechanism and a survey operation by each survey means. Stopped. In the building survey apparatus, based on the control instruction signal transmitted from the terminal computer side, various survey data primarily stored in the memory means is transmitted from the survey terminal side to the terminal computer. In the building survey apparatus, predetermined diagnostic data is created in the diagnostic data creation unit based on the survey data and the position data in the terminal computer. In the building survey device, the diagnostic data creation unit compares the reference value data stored in the storage unit with the test sound data wirelessly output from the survey terminal, for example, and numerically indicates the content and extent of the malfunction that has occurred on the wall surface.

  The suspended mobile device 60 is precisely fixed and held at a predetermined position by driving the self-propelled lateral movement mechanism 62 in the state where it is installed in the survey target building 5 as described above. The suspension mobile device 60 suspends the survey terminal 3 with the suspension wire 10 and moves it up and down along the wall surface 6 so that a predetermined survey is performed. When the suspension mobile device 60 moves the survey terminal 3 up and down along a predetermined area and ends the survey of the area, the self-propelled lateral movement mechanism 62 is driven from the terminal computer 4 side based on the control instruction signal. . The suspended mobile unit 60 can be continuously surveyed by shortening the set-up time by the positioning and fixing after the self-propelled lateral movement mechanism 62 is driven and moved accurately after the survey is completed. And

  As described above, the hanging mobile unit 60 is controlled by precisely controlling the feeding amount or winding amount of the hanging wire 10 with respect to the wire drum 19, for example, instead of the above-described self-propelled lifting mechanism 23. Can be moved up and down along the wall surface 6. The suspension mobile device 60 further reduces the weight of the survey terminal 3 by removing the self-propelled lifting mechanism 23, and performs a precise survey by moving the survey terminal 3 up and down along the wall surface 6 in a more stable state. It is possible to do. The suspended mobile device 60 performs data processing on the output from the wire drum sensor 69 in the mobile device control circuit unit 61 to create position data of the survey terminal 3, and the terminal computer 4 via the third wireless unit 64. To send.

  Needless to say, the suspension mobile device 60 is not limited to the above-described configuration, and the suspension wire feeding / winding mechanism 63 and the self-propelled lifting mechanism 23 on the survey terminal 3 side cooperate to investigate the suspension terminal. 3 may be configured to move up and down along the wall surface 3. In the suspension mobile device 60, for example, the control instruction signal is exchanged with the survey terminal 3 by the first wireless unit 25 and the third wireless unit 64, and the suspension wire feeding / winding mechanism 63 and the self-propelled lifting mechanism are provided. 23 to be synchronized.
