Description

This application is the basis for a domestic priority claim application to be submitted at a later date.
INDUSTRIAL APPLICABILITY The present invention includes a structure estimation device for a reinforced concrete structure used for estimating the diameter of at least two-layered reinforcing bars, so-called mesh reinforcing bars, which are contact-arranged at orthogonal intersections inside the concrete of a reinforced concrete structure. Regarding the method. The reinforcing bar of the present invention includes both a reinforcing bar called a round steel having a circular cross section and a reinforcing bar called a deformed reinforcing bar having an uneven surface, but in the present specification, it is treated as a round steel having a circular cross section for convenience. I will do it.

In recent years, many reinforced concrete structures such as buildings and bridges have been reinforced as a preparation for a large earthquake that is expected to occur in the near future and as a countermeasure against aging. When performing this reinforcement work, it is necessary to grasp the position of the reinforcing bar buried in the concrete of the reinforced concrete structure and the diameter of the reinforcing bar.

Conventionally, as a method for estimating the diameter of a reinforcing bar adopted when information on the reinforcing bar cannot be obtained from a design drawing at the time of construction, for example, an estimation method using an electromagnetic wave radar is known. In this method for estimating the diameter of the reinforcing bar, as shown in the plan view of FIG. 1A, the upper and lower reinforcing bars 0101 and the lower reinforcing bar 0102 are arranged in two upper and lower layers so as to be in contact with each other at the orthogonal intersection 0103 inside the concrete C. First, the electromagnetic wave is radiated from the transmitting antenna of the electromagnetic wave radar to the inside of the concrete C with respect to the floor 0100, which is a structure, and the reflected wave reflected by each of the upper reinforcing bar 0101 and the lower reinforcing bar 0102 is received by the receiving antenna. Measure the burial depth (covering depth) of the upper reinforcing bar 0101 and the lower reinforcing bar 0102.

The buried depths DU and DL (m) of the upper reinforcing bar 0101 and the lower reinforcing bar 0102 are the time until the electromagnetic wave radiated from the transmitting antenna is reflected by the upper reinforcing bar 0101 and the lower reinforcing bar 0102 and received by the receiving antenna. It is obtained by multiplying half (one way) of (s) by the velocity V (m / s) of the electromagnetic wave transmitted through the concrete C, and is expressed by Equations 1 and 2.
DU = (1/2) x TU x V formula 1
DL = (1/2) x TL x V formula 2

At this time, the speed of the electromagnetic wave in the air (vacuum) is 3 × ¹⁰⁸ (m / s), and the speed V when the electromagnetic wave passes through the concrete C is the relative permittivity peculiar to the concrete C as a medium. It is determined and expressed by Equation 3. The standard relative permittivity ε _r of concrete C, which is neither dry nor wet, is 6 to 8.
V = (3 × 10 ⁸ ) / (ε _r ) ^1/2 formula 3

Therefore, the buried depths DU and DL (m) of the upper reinforcing bar 0101 and the lower reinforcing bar 0102 are represented by the formulas 4 and 5 according to the formulas 1 to 3.
DU = (1/2) × {(3 × 10 ⁸ ) / (ε _r ) ^1/2 } × TU equation 4
DL = (1/2) × {(3 × 10 ⁸ ) / (ε _r ) ^1/2 } × TL formula 5

Then, in this method of estimating the diameter of the reinforcing bar, as shown in the enlarged cross-sectional view at the orthogonal intersection point 0103 in FIG. 1B, the diameter of the upper reinforcing bar 0101 is obtained from the difference between the buried depth DU of the upper reinforcing bar 0101 and the buried depth DL of the lower reinforcing bar 0102. I try to estimate φ.
As a method similar to this method for estimating the diameter of the reinforcing bar, for example, there is a method for estimating the diameter of the reinforcing bar described in Patent Document 1.

These work in cooperation with operating systems, device drivers, various programs, etc. The various programs and various data constituting the present invention are configured to efficiently utilize these hardware resources to execute various processes.

≪Chipset≫
A "chipset" is a set of large-scale integrated circuits (LSIs) that are mounted on the motherboard of a computer and have a communication function between the external bus of the CPU and a standard bus that connects memory and peripheral devices, that is, a bridge function. be. There are cases where a two-chipset configuration is adopted and cases where a one-chipset configuration is adopted. A north bridge is provided on the side close to the CPU and main memory, and a south bridge is provided on the side of the interface with a relatively low-speed external I / O on the far side.

(Northbridge)
The north bridge includes a CPU interface, a memory controller, and a graphic interface. The CPU may be responsible for most of the functions of the conventional north bridge. The north bridge is connected to the memory slot of the main memory via a memory bus, and is connected to the graphic card slot of the graphic card by a high-speed graphic bus (AGP, PCI Express).

(Southbridge)
The south bridge is connected to a PCI interface (PCI slot) via a PCI bus, and is responsible for I / O functions and sound functions with an ATA (SATA) interface, a USB interface, an Ethernet interface, and the like. Incorporating circuits that support PS / 2 ports, floppy disk drives, serial ports, parallel ports, and ISA buses that do not require or do not require high-speed operation will hinder the speeding up of the chipset itself. Therefore, it may be separated from the chip of the south bridge and assigned to another LSI called a super I / O chip. A bus is used to connect the CPU (MPU) to peripheral devices and various control units. The buses are connected by a chipset. The memory bus used for connection with the main memory may adopt a channel structure instead of the memory bus in order to increase the speed. A serial bus or a parallel bus can be used as the bus. In the parallel bus, while the serial bus transfers data bit by bit, the original data itself or a plurality of bits cut out from the original data are grouped together and transmitted over a plurality of communication paths at the same time. A dedicated clock signal line is provided in parallel with the data line to synchronize data demodulation on the receiving side. It is also used as a bus that connects a CPU (chipset) and an external device, and includes GPIB, IDE / (parallel) ATA, SCSI, PCI, and the like. Since there is a limit to the speedup, the data line may be a serial bus in the improved version of PCI Express or the improved serial ATA of parallel ATA.

≪CPU≫
The CPU also outputs information consisting of signals to the main memory by reading, interpreting, and executing instruction sequences called programs in the main memory in order. The CPU functions as a center for performing calculations in the computer. The CPU is composed of a CPU core portion that is the center of calculation and a peripheral portion thereof. Inside the CPU, a register, a cache memory, an internal bus that connects the cache memory and the CPU core, a DMA controller, a timer, and a north are used. The interface with the connection bus with the bridge is included. A plurality of CPU cores may be provided in one CPU (chip). Further, processing may be performed by a graphic interface (GPU) or FPU in addition to the CPU.

≪Non-volatile memory≫
(HDD)
The basic structure of a hard disk drive consists of a magnetic disk, a magnetic head, and an arm on which the magnetic head is mounted. As the external interface, SATAA (ATA in the past) can be adopted. A sophisticated controller, such as SCSI, is used to support communication between hard disk drives. For example, when copying a file to another hard disk drive, the controller can read the sector and transfer it to another hard disk drive for writing. At this time, the memory of the host CPU is not accessed. Therefore, it is not necessary to increase the load on the CPU.
As the non-volatile memory, an SSD composed of a "NAND flash" may be adopted together with the HDD, or may be replaced with the HDD.

≪Main memory≫
The CPU directly accesses and executes various programs on the main memory. The main memory is a volatile memory and DRAM is used. The program on the main memory is expanded from the non-volatile memory onto the main memory in response to the program start command. After that, the CPU executes the program according to various execution instructions and execution procedures in the program.

≪Operating system (OS)≫
The operating system is used to manage the resources on the computer for the application to use, to manage various device drivers, and to manage the computer itself, which is the hardware. Small computers may use firmware as the operating system.

≪Device driver≫
A device driver is a program that controls the hardware of a device to make various devices attached to a computer available to users and applications via an operating system.

≪BIOS≫
The BIOS is the one that causes the CPU to execute the procedure for booting the computer hardware and running the operating system, and most typically, the hardware that the CPU first reads when the computer boot command is received. .. Here, the address of the operating system stored in the disk (nonvolatile memory) is described, and the operating system is sequentially expanded to the main memory by the BIOS expanded in the CPU and put into an operating state. The BIOS also has a check function for checking the presence or absence of various devices connected to the bus. The result of the check is saved in the main memory and made available by the operating system as appropriate. The BIOS may be configured to check an external device or the like.

≪I / O controller≫
The I / O controller is used to connect to an external device. The USB connector is one example.

≪USB, IEEE1394 connector, LAN terminal, etc.≫
USB, IEEE1394 connector, LAN terminal, etc. are the most typical communication standard interfaces.

The above is a configuration commonly used in the description of the hardware configuration in all the embodiments in the present specification.
<Embodiment 1>

This embodiment mainly relates to claims 1, 4, and 7.
<Outline of Structure Estimator for Reinforced Concrete Structure>

The structure estimation device for the reinforced concrete structure according to the present embodiment radiates electromagnetic waves into the concrete of the reinforced concrete structure and reflects them at the upper and lower reinforcing bars arranged so as to be in contact with each other at orthogonal intersections inside the concrete. By receiving the reflected wave that returns, so-called hyperbola information, which is waveform information in the depth direction of the reflected wave, is acquired for each of the upper reinforcing bar and the lower reinforcing bar.

In such a structure estimation device for a reinforced concrete structure, not only the diameter of the reinforcing bar of the upper reinforcing bar but also the diameter of the reinforcing bar of the upper reinforcing bar is acquired because the hyperbola information of the upper reinforcing bar and the lower reinforcing bar that are arranged inside the concrete of the reinforced concrete structure and are in contact with each other at orthogonal intersections is acquired. It has the effect of being able to estimate the reinforcing bar diameter of the lower reinforcing bars.
<Embodiment 1 Structure estimation device configuration of reinforced concrete structure>

As shown in FIG. 3A, the structure estimation device 0360 of the reinforced concrete structure of the present embodiment is a computer such as a notebook personal computer, and is inside the concrete C of the reinforced concrete structure (floor of the building in the present embodiment) 0300. It is a device that estimates the diameters of the upper and lower two layers of the upper and lower reinforcing bars 0301 and the lower reinforcing bars 0302 arranged so as to be in contact with each other at the orthogonal intersection 0303 using a carriage-shaped electromagnetic wave radar 0350. In the present embodiment, the structure estimation device 0360 and the electromagnetic wave radar 0350 are configured to transmit and receive data via a wireless run, and the transmission and reception of data via this wireless run radiates the electromagnetic wave radar. I try to do it without it.
In the present embodiment, the case where the reinforcing bar group arranged inside the concrete C has two upper and lower layers is illustrated, but the case where the reinforcing bar group has three or more layers is naturally applicable.
Further, the structure estimation device 0360 and the electromagnetic wave radar 0350 may be configured to transmit / receive data via a wired connection, or may be configured to transmit / receive data via a memory such as USB. good.

The electromagnetic wave radar 350 forming a trolley is a radar that radar-scanns the surface of the structure perpendicular to the reinforcement arrangement direction of the upper reinforcement 0301 and the lower reinforcement 0302, and has a transmission antenna 0351 that radiates electromagnetic waves toward the inside of the concrete C. The receiving antenna 0352 that receives the reflected wave reflected and returned by the upper reinforcing bar 0301 and the lower reinforcing bar 0302 (only the electromagnetic wave reflected by the upper reinforcing bar 0301 is shown in FIG. 3A), and the upper reinforcing bar 0301 and the lower reinforcing bar that are radiated from the transmitting antenna 0351. It is equipped with a radar screen 0353 that displays the waveform of the electromagnetic wave that is reflected by 0302 and returns to the receiving antenna 0352. In this case, a range finder is built in the wheel 0354 so that the distance from the transmission position to the reception position when scanning the surface of the structure by radar can be known. Since the moving speed when performing radar scanning with the electromagnetic wave radar 350 does not contribute to the estimation of the diameters of the upper and lower reinforcing bars, the radar scanning of the electromagnetic wave radar 350 is either automatic or manual. May be good.

When radar scanning the surface of the structure using such an electromagnetic wave radar 350, the electromagnetic wave radar 350 is moved orthogonally to the reinforcing bar arrangement direction of the upper layer reinforcing bar 0301 and orthogonal to the reinforcing bar arrangement direction of the lower layer reinforcing bar 0302. Need to move.
In determining the direction in which the electromagnetic wave radar 350 is moved, first, the radar scanning is performed by the electromagnetic wave radar 350 to grasp the reinforcing bar arrangement positions of the upper reinforcing bar 0301 and the lower reinforcing bar 0302. Then, on the surface of the structure, a ruled line La is drawn between the upper reinforcing bars 0301 whose bar arrangement position is determined, and a ruled line Lb is drawn between the lower reinforcing bars 0302 whose bar arrangement position is also determined, and these ruled lines La, Lb are drawn. The electromagnetic wave radar 350 is automatically or manually moved along the line.

Here, when the electromagnetic wave radar 350 is a self-propelled type, for example, it may be moved by using GPS (Global Positioning System) in outdoor radar scanning such as on the roof of a building or a bridge. Further, for example, in radar scanning indoors such as on the floor of a building, a plurality of beasons are arranged inside the building, and a receiving terminal for the beacon is mounted on the electromagnetic wave radar 350 so as to be guided by the plurality of beasons to move. You may do it.
<Embodiment 1 Configuration Function Block>

As shown in FIG. 3B, the structure estimation device 0360 of the reinforced concrete structure of the present embodiment includes a hyperbola information acquisition unit 0361, an upper reinforcing bar diameter acquisition unit 0362, a relative permittivity-specific hyperbola curve information acquisition unit 0363, and mounting concrete. It has a relative permittivity acquisition unit 0364, a hypobola curve information acquisition unit 0365 for each lower layer reinforcing bar estimated diameter, and a lower layer reinforcing bar diameter acquisition unit 0366.
<Embodiment 1 Configuration Function Block Hyperbora Information Acquisition Unit>

The "hyperbola information acquisition unit 0361" radiates electromagnetic waves from the transmitting antenna 0351 of the electromagnetic wave radar 0350 toward the inside of the concrete C, and is arranged in the concrete C so as to make contact at the orthogonal intersection 0303. By receiving the reflected wave reflected and returned by the upper reinforcement 0301 and the lower reinforcement 0302 by the receiving antenna 0352, the hyperbola information which is the waveform information in the depth direction of each of the reflected waves of the upper reinforcement 0301 and the lower reinforcement 0302 is acquired.

Here, when the electromagnetic wave radar 350 is moved perpendicular to the reinforcement arrangement direction of the upper reinforcing bar 0301, the electromagnetic wave radiated from the transmitting antenna 0351 to the inside of the concrete C has a spread in the traveling direction and the retreating direction. Therefore, as shown in the two-dimensional image (cross-sectional image) of FIG. 3C, for example, the oblique reflected wave R1 from the front upper reinforcement 0301 even at the position P1 before the electromagnetic wave radar 0350 passes directly above the upper reinforcement 0301. Will be received. At this time, on the radar screen 0353 of the electromagnetic wave radar 350, 1/2 time t1 until the electromagnetic wave radiated at the position P1 becomes the reflected wave R1 and returns, or the distance d1 to the upper reinforcing bar 0301 is displayed directly under the position P1. It has become so. The distance d2 from t2 for the electromagnetic wave to return as a reflected wave or the distance d2 from the electromagnetic wave radar 0350 to the upper reinforcing bar 0301 is the shortest when the electromagnetic wave radar 0350 passes the position P2 directly above the upper reinforcing bar 0301, and then. When the electromagnetic wave radar 0350 passes through the position P3, the oblique reflected wave from the rear upper reinforcing bar 0301 is received, and on the radar screen 0353 of the electromagnetic wave radar 350, the electromagnetic wave radiated at the position P3 is the reflected wave R3. Half of the 1/2 hour t3 hours until returning is converted into the distance d3 to the upper reinforcing bar 0301 and displayed directly under the position P3.
As a result, the radar screen 0353 displays a symmetrical chevron waveform with the upper reinforcing bar 0301 as a peak, that is, a hyperbola waveform (information) which is information on the waveform in the depth direction.
The image processing of this radar information is generally described as follows. For example, the position of the center of gravity of the bottom of a trolley equipped with an electromagnetic wave radar is set as the origin position of radar radiation, and the reflection time from the reinforcing bar by the radar (constant times the round-trip time or one-way time) as a function of the position on the straight line of this origin position. Or, it expresses the burial depth (concrete thickness) of the reinforcing bar when it is assumed that the reinforcing bar is located just below the origin.

As shown in the upper part of FIG. 3D, this hyperbola waveform has the sharpest hyperbola waveform 1 at the top of the chevron when the embedding depth of the reinforcing bar is shallow, and the chevron becomes deeper as the embedding depth of the reinforcing bar having the same diameter as this reinforcing bar becomes deeper. It is characterized by a loose hyperbola waveform 2, 3 and 4 at the top. Further, as shown in the lower part of FIG. 3D, the hyperbola waveform has a feature that the top of the chevron becomes a sharp hyperbola waveform 5 in the case of a thin reinforcing bar, and the top of the chevron becomes a loose hyperbora waveform 6 in the case of a thick reinforcing bar. ..

<Embodiment 3 Structure estimation device configuration of reinforced concrete structure>

As shown in FIG. 9A, in the structure estimation device 0960 of the present embodiment, the difference from the previous embodiment is that the hyperbola information acquisition unit 0961 acquires a plurality of hyperbora information in two orthogonal directions.

In that respect, the other configurations are the same as in the previous embodiment.

Here, when the depth measurement by the radiation of the electromagnetic wave is performed just above the intersection of the upper rebar and the lower rebar when acquiring the hyperbola information of the upper rebar, the reflected wave from the lower rebar interferes with the reflected wave from the upper rebar. Therefore, this affects the accuracy of the depth, which is the hyperbora information of the upper reinforcing bar, and accurate depth measurement cannot be performed.
In order to deal with this problem, the structure estimation device 0960 of the present embodiment takes the above-mentioned countermeasures.

Radar scanning is performed along the horizontal broken line so as to pass through the points x1, x2, x3, ... Radar scanning is performed along a vertical broken line so as to pass through a plurality of measurement points y1, y2, y3, ....

In the structure estimation device 0960 of the present embodiment, the following equation 6 is used as a statistical upper reinforcement diameter acquisition means, and the measurement points x1, x2, x3, ... And the measurement points y1, y2 are obtained by radar scanning as described above. , Y3, ... By applying the measured values obtained in Equation 6, the average of the measured values of the upper and lower two points and the left and right two points (for example, the measured points located in the circle in FIG. 9B) adjacent to each other. By calculating the difference between the above, it is possible to average the errors such as the inclination of the reinforcing bars.
Δd = | ((dx2 + dx1) / 2)-((dy2 + dy1) / 2) | Equation 6

At this time, for example, the value of the upper reinforcing bar can be corrected by recalculating each value by changing the combination of the above four measurement points of the upper, lower, left and right as well as the upper and lower average and the left and right average. In addition, in the calculation result of the reinforcing bar diameter by the formula 6, when a different numerical value is prominently shown in other numerical values, it is excluded by passing through a filter.
