  After the Great East Japan Earthquake, building owners who own buildings needed to understand the damage situation of all the buildings they own and take measures against damaged buildings. Since the damage situation cannot be ascertained without actually going to the site, prioritization of surveys and countermeasures immediately after the earthquake is a major issue. In addition to such a large damage situation, it has come to be required to create an item of building management by generating and storing the slope as data on a regular basis. Unlike the major damage, the daily change has a minimal daily change and is difficult to judge visually. It is possible to acquire this minimum inclination in time series by the leveling of the foundation of the building. However, this leveling work has to be carried out by a plurality of workers one by one, which is time consuming and expensive, and is not suitable for time-series inclination measurement. On top of that, it has been found that if the inclinometer is made more accurate, the problem that the inclination due to the influence of temperature must also be taken into account.

  The technique described in Patent Document 1 seeks to evaluate the deformation of a building by obtaining vibration data generated on each floor, and manages the building by generating and storing the slope as data for daily changes. It is not intended to be a single item.

  Patent Document 2 describes that a building inclination sensor is used to measure the inclination of a building, and the inclination is an inclination exceeding 1 °, such as 1 ° or 1.2 °. It is not described that data is acquired even for a minute inclination in which a change in temperature, such as 3 ″ (seconds) or 5 ″, in which the influence of the influence of the change must be considered, is affected. .

  Patent Document 3 describes that the influence of solar radiation on the inclination of sleepers is erased, but when there is an influence of solar radiation in the measurement direction like a building, the effect of temperature on the building is also erased. Is not described.

  The above-mentioned patent document does not describe providing the building health status result including the building health status data.

  The present invention acquires the influence of building-specific temporal temperature changes on the inclination of the building as the daily inclination as data, and measures the inclination of the building over time so that a minute inclination angle can be obtained. For example, it is an object of the present invention to make it possible to obtain health data of a building by acquiring inclination data even for a minute inclination such as 3 ″ (seconds) or 5 ″.

  When building inclination is automatically measured by accumulating data and performing building inclination measurement as a commissioned work, it is required to measure the inclination or settlement over 50 m with an accuracy of about 1 mm in a building with a width of 50 m. It is done. A change of about 1 mm is a region caused by a temperature change.

When the width is 50m and the inclination after 50m is 1mm,
1 mm ÷ 50000 mm × 206265≈4 ″
It becomes. Similarly calculated, a slope of 0.7 mm for 3 ″ and a slope of 1.2 mm for 5 ″. In the case of such an inclination, it is necessary to eliminate the influence of the temperature change of the building. For the measurement of such inclination, the present invention uses a bubble tube that can measure the movement of bubbles with a camera and has a radius of 10,000 mm or more when moving the bubbles, preferably a radius of 20000 to 50000 mm. It was supposed to be. The radius of 10,000 mm or more is an important factor when measuring a minute building inclination due to temperature change effects such as indoor temperature and solar radiation. It is not necessary to use a bubble tube having such a radius in the collapse measurement of an inclined surface such as a mountain.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a schematic configuration of a centralized building management apparatus, that is, a building health management apparatus 100 according to an embodiment of the present invention. The building health management apparatus 100 can be configured with a personal computer.

  As shown in FIG. 1A, the building health management apparatus 100 is equipped with a camera to automatically measure the inclination of the building, and the building installation inclination sensors A, B, C, D having communication means, and the building installation inclination. And a management unit 112 (see FIG. 4) connected to the sensor by the communication means 106. The building tilt sensor detection data is transmitted to the management unit 112 via the communication means, and the received data is analyzed and analyzed. The recorded data can be recorded in the recording unit. The building installation tilt sensor is a sensor that is installed in a building where the identity of the building is determined, and is a sensor that continuously measures the tilt angle of this building due to the effect of temperature changes on this building. It is installed on the upper floor, lower floor, or upper floor and lower floor, respectively, and used for measurement. Here, it is called a building installation tilt sensor. Hereinafter, this building installation inclination sensor is referred to as an inclination sensor.

  As the tilt sensor, a sensor that can measure the tilt of the building due to the influence of a temperature change on the building, that is, a minute tilt angle is used, but a bubble tube having a maximum radius as described later can be typically used. . The reason for setting the maximum radius is that it has a decomposition capability, can measure the movement of minute bubbles, and can measure a minute inclination angle. Therefore, the present invention is not limited to a bubble tube having a maximum radius. As an inclinometer applicable to the present invention, a commercially available precision clinometer with a resolution of 0.002 °, 0.004 °, and a tilt by measuring the interelectrode potential with a bubble sensor. High precision inclinometer, bore hold inclinometer, horizontal accuracy is 0.001 °, measurement range is ± 5deg. There is an inclinometer that can remove the zero drift due to factors such as temperature, shock, and vibration.

  An inclination measuring meter using a bubble tube has the following advantages when applied to the present embodiment, and is preferably applied in the present embodiment.

Advantages of using a bubble tube:
1) When an inclination occurs, the inclination can be visually confirmed.
When there is movement, it can be easily identified whether the building is inclined or the device is abnormal.
The tilt cannot be checked directly with other methods,
It is necessary to visualize the coordinates in a biaxial graph such as an XY fluctuation graph or a round bubble tube image. Moreover, the identification is difficult.
2) Not easily affected by electromagnetic waves.
Various electromagnetic waves fly in and out of the building, and electronic ones may be affected.
The bubble tube type is advantageous because it uses liquid inside.
In buildings such as hospitals where the use of mobile phones is restricted, there is a risk that the more accurate the inclinometer, the greater the impact. There is a need to consider the effects of lightning.
3) The tilt measuring instrument using the bubble tube is an excellent measuring instrument that has been stable by the old method, is an ultimate instrument, and will remain in the future.

Thus, the bubble tube having the maximum radius is easy to manufacture, easy to handle, and can provide high accuracy, and is preferably used in this embodiment. In the following description of the embodiment, a bubble tube having this maximum radius will be described as an example.

  The building health management apparatus 100 is operated by the commissioned business execution person in charge 107. The commissioned business execution person in charge 107 is a contractor who reports and contracts the acquisition of inclination data or inclination data and subsidence data of many buildings shown in this embodiment, and is responsible for operating the computer. Say.

  The inclination sensors A, B, C, and D are located at the four corners and the first floor (or equivalent positions) of the roof (or the highest floor), which is the top floor of a building, for example, a high-rise building as shown in FIG. It is installed in a total of 8 places at the four corners of the base floor. It does not have to be the top floor or the first floor, but may be an upper floor or a lower floor. Here, they are called the upper floor and the lower floor. In a building with a concept such as the 30th floor or the 40th floor, tilt sensors may be provided in the middle level of the middle so as to correspond to the tilt sensors A, B, C, and D. Since it is recommended to install tilt sensors on the top floor, which is the top floor, or on the first floor, which is the base floor, an example in which tilt sensors are installed on these floors will be described below.

  In the figure, inclination sensors A and B installed at the two corners of the basic floor seen from the front and building inclination sensors C and D installed at the two corners of the roof seen from the front are described. The number of tilt sensors is not limited to this. By providing it at the four corners of the same floor, it is possible to measure the inclination in the horizontal direction, and by providing it at the upper and lower floors, the inclination in the vertical direction, and further by providing it on the same floor and the upper and lower floors, the inclination in the torsion direction can be measured It will function effectively for the acquisition of precise medical examination data by analysis.

  The inclination data measured by the inclination sensors A, B, C, and D are transmitted to the management unit 112 via the inclination sensors 101 to 104 and the communication unit 106 that include communication devices that can transmit the inclination data. The group of inclination sensors 101 to 104 becomes the group of inclination sensors 110 for the building. A tilt sensor is set for each building. A small computer (microcontroller) can be incorporated in each transmission device, and the converted digital information can be communicated at predetermined intervals.

  The identity of the building to be measured for inclination, the identity of the inclination sensor, and the data related to the identity of the building and the identity of the inclination sensor are stored in the storage unit, that is, stored. Measurements or measurement data for a large number of buildings are distinguished for each building.

  The communication means 106 is connected to the Internet line and acquires inclination data of other buildings by the same means.

  In the building 1 illustrated in FIG. 1B, a roof surface 2, a base floor surface 3, a north side wall surface 4, and a south side wall surface 5 are displayed. The ground is indicated by 6.

  FIG. 2 is a diagram for explaining a tilt sensor employed in the present embodiment.

  FIG. 2A shows a combination of a rod-shaped bubble tube 20 as a tilt sensor and a camera 21 as an imaging device.

  The rod-shaped bubble tube 20 is a uniaxial bubble tube in which bubbles 23 are placed in a rod-shaped main body 22. As the main body 22 is tilted, the bubbles 23 move in a uniaxial direction, and the movement state is photographed by the camera 21 and converted into digital information. A bubble image is taken with a digital camera, and the inclination direction and angle of the main body 22 are simultaneously obtained from the position of the center of the bubble in the image.

The shooting instruction is performed by a microcomputer. By obtaining the center position of the bubble in the photographed image, the direction and angle of inclination of the main body 22 can be known. When the body 22 is inclined an angle theta _X in the X direction, the center position of the air bubble of the rod-shaped bubble tube radius of curvature R is shifted by [Delta] X.
ΔX = Rsinθ _X
When the angle is small,
ΔX = Rθ _X
Can be approximated. Let Δi _X be the change in the X-axis direction of the pixel value on the screen. If the interval in the real space of one pixel is a, the relationship between the displacement of the pixel in the X-axis direction and the inclination of the main body 22 is given by the following equation.
aΔi _X = ΔX = Rθ _X
a / R is a change in angle with respect to a change in one pixel, that is, a resolution of angle measurement. This is the advantage of using a rod-shaped bubble tube, and precise tilt data can be obtained.

In the expression ΔX = Rsinθ _X , let us examine the case where R is 200 mm and the conventional case where 2000 mm. Since θ _X is treated as a constant, ΔX is 100 times larger in the case of 20000 mm than in the case of 200 mm, and changes in angle with respect to a change in one pixel, that is, resolution of angle measurement, and the influence of temperature change The resolution of the angle measurement is acquired for a slight change in inclination due to, and measurement is possible.

  In the case of this example, in order to obtain such an accurate resolution, three rod-shaped bubble tubes having a radius R = 20000 mm are arranged side by side and fixed as shown in FIG. Three rod-shaped bubble tubes arranged side by side can be arranged at T as shown in FIG. 2 (c) so as to be able to cope with all directions.

  As described above, the movement of the bubble can be measured by the camera, and the radius when the bubble moves is 10000 mm or more in order to obtain the resolution of the angle measurement even for a slight inclination change due to the temperature change. A bubble tube having a maximum radius of 20000 to 50000 mm is preferably used. Compared to the conventional 200 mm, a resolution of 50 times or 100 times or more can be obtained. Thus, the bubble tube which can measure the inclination by the influence of the temperature change with respect to a building is provided. Thereby, the inclination angle of the building in the measurement direction of the building is measured from the movement of the bubbles in the bubble tube. The inclination of the building due to the influence of temperature change, the abnormal inclination of the building exceeding this inclination, and the inclination phenomenon appearing as further distortion are observed from the movement of the bubbles in the bubble tube.

  The inclination angle data of the building due to the influence of the temperature change is stored in advance in the storage means. The inclination measurement data measured by the inclination sensor is acquired, and the inclination of the building on the upper and lower floors of the building or the upper and lower floors of the building is calculated from the inclination measurement data. It is obtained by performing an operation that removes.

  It can be compared with the effect information of the temperature change over time stored in the storage unit and displayed on the screen, and the comparison can be made, so that it can be compared mechanically or artificially in the measurement direction of the building. Acquired as the inclination of the building. Artificial means that it was acquired as information by being observed and converted into data. In the removal calculation by comparison with the influence information of the temperature change over time stored in the storage unit, not only the inclination angle due to the influence of the temperature change of the daily change but also the previous day or every other day was measured from the data of the current day. It includes eliminating the effects of temperature changes by removing the data. According to this, not only the absolute change degree but also the relative change degree with the data of the previous day or every other day can be read.

  FIG. 3 shows a circuit diagram employed in a rod-shaped bubble tube. The camera module, DC-DC converter, wireless module, microcomputer, LED, etc. were combined as shown in the circuit diagram shown in FIG. We were able to transmit the image data.

  FIG. 6 is a diagram illustrating an assumed building having a height of 20 m and a height of 60 m and a width of 50 m as a building. This is the same as that displayed in FIG. The building 1 is in a state where the south side wall 5 is inclined as shown in the figure under the influence of temperature.

  The inventors assumed that the influence on the daily fluctuation of the inclination of the building was mostly due to solar radiation. However, it was found that the cause of daily fluctuation was not the temperature change due to solar radiation to the building, but the influence of expansion and contraction of the building structure due to the use of air conditioning. Observed fluctuations in the east-west direction and the direction of expansion / contraction due to solar radiation may appear opposite. If solar radiation is the main cause, the fluctuation range is large in fine weather (long solar radiation time), and the fluctuation range in cloudy weather. Is expected to be small, but in practice it was found that the relationship between solar radiation time and fluctuation range is not significant. It was found that the influence of strong winds was small. In measuring the inclination angle of a building, the temperature effect on the daily fluctuation of the inclination of the building cannot be ignored. The temperature effect can be said to be a phenomenon peculiar to buildings.

The building changes daily by about 0.001 degrees in a high-rise building on the 7th floor due to complex factors such as internal and external temperatures due to cooling and heating, solar radiation, rain and wind, and impact. It was found that the actual true building inclination angle can be calculated by making it possible to observe this. Therefore, in this embodiment, in order to observe and diagnose the health state of a building, a building inclination sensor capable of measuring a daily change effect due to a temperature of about 0.001 degrees is used in a high-rise building of about 7 floors. . Observe the change over time by calculating the actual building inclination data by comparing the data with the numerical value of the effect of temperature over time stored in the storage unit. Or it is diagnosed and acquired whether it is healthy when it is minute. It is determined mechanically or by the judgment of the supervisor (including both), the judgment information is acquired, and the screen is displayed. The change over time is a linear change, but may change in a curved manner beyond the linear change, and the typical change in the curved shape is regarded as a change caused by the distortion phenomenon of the building.
In FIG. 6, it is assumed that the building is slightly inclined to the south side due to the temperature change.

  When affected by the temperature, the building 1 appears to have a larger elongation on the south side wall 5 than on the north side wall 4, for example.

The inclination angle on the rooftop is calculated from the result of measuring the movement of the bubbles with the inclination sensor having the rod-shaped bubble tube shown in FIG. 2, and the degree of influence is analyzed. According to the measurement by the inventors, the bubbles moved 0.3 mm to 0.5 mm under the influence of temperature. from now on,
3 mm → 0.3 / 20000 × 206265 ″ ≈3 ″ (seconds)
0.5mm → 0.5 / 20000 × 206265 ″ ≒ 5 ″ (seconds)
An inclination of 3 ″ (seconds) to 5 ″ (seconds) is an overhang of 0.7 to 1.2 mm toward the south of the building. This numerical value is compared with the degree of inclination due to the influence of the stored temperature change.

  FIG. 7 shows measurement data indicating the degree of inclination influence due to the temperature effect on the seventh floor of a certain building (university research institute building). As the tilt sensor, the tilt sensor provided with the rod-shaped bubble tube shown in FIG. 2 was used. The rod-shaped bubble tubes were accurately measured using three sets of uniaxially configured ones in parallel, arranged in both directions of north-south and east-west, and tilt data in the north-south direction were obtained as shown in FIG. The measurement was performed over a week of 2015. 9/17 to 9/23, and data was acquired. Data were obtained for other weeks, but the measurement data results were similar.

  As shown in FIG. 7, the inclination was measured about 2 mm between approximately 0.002 deg and -0.002 deg. As measurement data of the building, for example, a 1 mm slope was measured at a position 50 m ahead by bubble measurement of a rod-shaped bubble tube having a radius of 20000 mm. That is, in the diagram shown in FIG. 6, the basic measurement data has an inclination of 2 mm with respect to the A point at the B ′ point. It corresponds to 1 mm in 4 seconds. Under such circumstances, the inclination of the building due to the influence of temperature was measured, and the result is shown in FIG.

  With regard to the inclination angle, the valley shape data was acquired during the daytime, and the distribution shape of the mountain shape data was acquired at night.

  The valley shape data at daytime, the mountain shape data at night, or both are data indicating the influence of each temperature. A drawing in which the measurement analysis time is continued and which is statistically converted into data over time can be used as a temperature influence drawing.

  The inventors of the present invention do not know an example in which the inclination of the building is measured with such an accuracy that the temperature is affected. The present embodiment is considered to make up the arrow. The precision level has a long radius, but the precision level does not measure the inclination due to the influence of temperature, and there is no document describing that the influence of temperature is measured.

  In this embodiment, in order to measure the inclination of the building with an accuracy enough to affect the temperature, a rod-shaped bubble tube having a radius of 20000 mm is used, and it is confirmed that the bubble can operate at this radius. Adopted a bubble tube. Even if it is not a rod-shaped bubble tube, a bubble tube having such a radius can also be adopted. As can be seen from FIG. 7, when the bubble tube has a radius of 20000 mm or more, the movement of the bubbles can be sufficiently observed. In addition, as can be seen from FIG. 7, the movement of the bubbles suggests that a 0.2 mm slope can be measured in a 50 m wide building so that jagged, detailed fluctuations are observed in the figure. Thus, even if the radius is not as large as 20000 mm, sufficient accuracy can be given to observation and building health diagnosis based on the observation.

  From the accuracy of the graph displayed in FIG. 7, it is presumed that the influence of the temperature change can be observed even if the radius is not 20000 mm. Desirably, it is recommended to use a bubble tube having a radius of 10000 mm or more, particularly 20000 mm or more and a radius of 30000 mm or less.

  Under the date of the calendar, the inclination angle of the building in the measurement direction of the building during a predetermined period was calculated. The inclination angle of the building due to the influence of temperature was measured from the movement of bubbles in the bubble tube, converted into data, and stored in the storage unit as inclination angle data due to the influence of temperature.

  Since the daily change graph of FIG. 7 shows that it is based on the specific shape and size of the building, it is desirable to obtain it as the reference data in the first year of observation. A value exceeding the reference graph value with the vertical width of the graph as an allowable value is regarded as an abnormal value. Or you may set the peak value and valley value of a reference | standard graph as a threshold value. A calculation is performed to remove the influence of the temporal temperature stored in the storage unit. Alternatively, the vertical width of the graph is displayed in a contrasted manner so that an abnormality in the measured value with respect to the allowable value can be determined. By performing the comparison display, an equivalent result can be acquired as information without calculation.

  FIG. 8 is a diagram showing a state of daily continuous inclination measurement by the inclination sensor.

  In FIG. 8, the tilt angle was measured according to the above-described measurement conditions by the tilt sensor including the three rod-shaped bubble tubes 20 in which the positions of the bubbles were adjusted.

  FIG. 8 shows measurement data acquired by three rod-shaped bubble tubes 20 in which the positions of the bubbles are changed to the center, the + side, and the − side. The weather of the day occurred. The function is the same. The rod-shaped bubble tube 20 at the top in the drawing was set under the same conditions as when the basic data was acquired. For the rod-shaped bubble tubes 20 at the center and the lower portion, the bubble position was set on the minus side. The data obtained from the central and lower rod-shaped bubble tubes 20 was used as reference data. The distribution state shown in the figure was obtained.

  The management unit 112 obtains the tilt measurement data, analyzes the tilt measurement data, calculates the actual tilt of the building, compares the calculated value with the data indicating the influence of the temperature change, and removes the calculation processing. As a result, the inclination angle of the building from which the influence of temperature change was removed was calculated, and the inclination of the building was statistically analyzed over time and converted into data. The removal may be performed by using the entire figure, using the vertical length of the display, the area of the figure, the feature of the figure, and the like.

  In this way, in the soft ground where liquefaction has occurred, when the tilt is gradually generated and accumulated due to repeated earthquakes, the process is about 1 mm in a building with a width of 50 m. Even when there is a slope due to the influence of temperature, monitoring can be performed while removing the influence of temperature. This makes it possible to identify elements that may be related to man-made disasters as well as natural slopes, and to obtain data for determining the necessity of building reinforcement.

  In the case of a building having a height of 60 m, there may be a difference in measurement data between the measurement data of the building inclination sensor arranged on the uppermost floor 2 and the measurement data 3 of the inclination sensor arranged on the basic floor 3. When such a phenomenon occurs, it can be seen that the building is distorted. Cracks are observed as one of the strains. This observation information is also reported. More expert evaluations may be included.

  A typical installation example is to obtain measurement data by installing building inclination sensors at the four corners of each of the upper and lower floors. Although the present embodiment is established even when there are three corners, two corners, or one corner, the following advantages can be obtained by installing the four corners.

  In the case where an inclination (an inclination after removing the effect of temperature change; the same applies hereinafter) occurs in three of the four corners of the upper floor or the lower floor, 3 between one corner and three corners. It can be inferred that cracks or cracks occurred on the corners. Similarly, in the case where inclination occurs at two of the four corners, it can be estimated that cracks or cracks have occurred between the two corners. Similarly, when an inclination occurs in one of the four corners, it can be estimated that a crack or a crack has occurred on one corner side between the three corners.

  When the inclination sensor installed in the upper floor and the lower floor corresponds to an inclination, it can be inferred that a crack or crack has occurred from the upper floor to the lower floor of the high-rise building. It tends to occur in tall buildings that are elongated in the horizontal direction.

  The present embodiment provides a method for estimating the health state of a building based on the measurement result by simply and quickly measuring the inclination or distortion. Here, when the inclination repeated every day due to the influence of temperature as described above is excluded, it is said that the case where the inclination is substantially zero or within a preset threshold is healthy.

  As for the measured angle change due to the temperature change effect on the seventh-story high-rise building, the measured data and the calculated angle change are stored in the storage unit. Even after the measurement year, the angle change is observed under the same conditions, and when the angle change is almost the same, this building is diagnosed and judged to be healthy in that year, along with the subsidence data that was diagnosed and judged healthy. Report data is created. When the angle change is recognized by human judgment or from the measurement data, a report to the effect that the health condition is recognized is generated together with the settlement amount data.

  FIG. 9 is a diagram illustrating a building subsidence phenomenon. In addition to the tilt phenomenon described above, the building has a sinking phenomenon. In the case of the present embodiment, the sinking phenomenon is a phenomenon of sinking in the vertical direction, and when tilting is accompanied at that time, it is regarded as a tilting phenomenon.

  Here, the amount of settlement of the building is not reflected in the amount of inclination.

  In order to measure the amount of settlement, the heights of temporary watermarks installed at the four corners of the building are calculated by leveling using the fixed point at a location away from the building as the height standard, and time series monitoring is performed.

  This data is added to the tilt measurement data first to form one report data.

Stored are data on the degree of influence of temperature on the building in the measurement direction of the building and the amount of settlement data measured by the settlement amount measuring device.
