Description

The present invention relates to a method and system for inspecting a seismic isolation device installed in an underground pit of a building or the like. In particular, the present invention relates to a method for inspecting a seismic isolation device that has advantages such as reducing the time and effort of inspection work, saving labor in compiling a report of inspection results, and shortening the time required to create a report.

Seismic isolation devices for buildings have become extremely popular in recent years. Academic societies, construction industry, and machinery and equipment industries involved in seismic isolation of buildings have established the ``Japan Seismic Isolation Structures Association,'' a general incorporated association. The association was established as a voluntary organization in June 1993. The association has established the ``Maintenance and Management Standards for Seismically Isolated Buildings'' and has published a pamphlet. It stipulates ``maintenance and inspection implementation guidelines for seismic isolation members, etc.''

An example of the current state of inspection work in accordance with the above "implementation guidelines" will be explained.
FIG. 7 is a side view schematically showing a deformation inspection (an example) of a laminated rubber type restoring seismic isolation device. Furthermore, "seismic isolation devices" are also called "bearings." FIG. 5A is a side view showing how the horizontal deformation of the laminated rubber is measured, and FIG. 6B is a side view showing how the vertical deformation of the laminated rubber is measured.
FIG. 8 is a side view schematically showing an inspector inspecting deformation of a laminated rubber type restoring support.
FIG. 9 is a diagram schematically showing an example of how a sliding bearing is inspected for deformation. 3A is a front view showing how the horizontal displacement of the slide plate 239 with respect to the slide bearing 231 is measured, and FIG. 1B is a plan view.

The laminated rubber type restoring support 131 shown in FIGS. 7 and 8 is mainly composed of a cylindrical laminated rubber 135 in which a large number of rubber layers and steel plate layers are laminated. Flanges 137 and 133 made of thick steel plates are bonded to the upper and lower surfaces of the laminated rubber 135. As shown in FIG. 8, a leg portion 113, which is a block made of reinforced concrete, is placed on top of the upper flange 137, and the underfloor beam 115 of the building is placed on top of the leg portion 113. The lower flange 133 rests on a reinforced concrete platform 111 (such as a concrete pile cap).

The laminated rubber type restoring support 131 allows horizontal displacement between the building and its foundation during an earthquake, and after the shaking of the earthquake has subsided, restores the displacement and restores the relative positional relationship between the two. It is intended to restore. Such restoration supports are placed at the four corners of the building. In addition to restoring bearings, sliding bearings without restoring performance (receiving only loads in the vertical direction, such as the weight of a building; described later with reference to FIG. 9) are also used.

When inspecting the laminated rubber type restoration bearing 131, the following two types of deformation measurements are performed (in addition, dimensional measurements and photographs are taken between the seismic isolation device and the building structure). The first type of measurement is the horizontal deformation shown in FIG. 7(A), and the other one is the vertical deformation (shrinkage in size) shown in FIG. 7(B). In addition, in FIG. 7(A), the side edge 135b of the laminated rubber 135 is drawn with an exaggerated inclination.

In FIG. 7(A), the upper end of the string 141b of the plumb bob 141 is attached to a predetermined position on the end of the upper flange 137 of the restoring support 131 (for example, one place on the west side or the north side). Then, use the ruler 143 to measure the position of the lower end (pointed) of the weight 141f hanging from the lower end of the string 141b. This measurement position is a position specified for a specific restoring support 131, and the measurement position is marked with a line or the like. Measurement of horizontal displacement at this fixed location will be performed at the time of building completion, five years later, and every 10 years thereafter. Then, the positional deviation (horizontal displacement of the laminated rubber 135) is measured and determined (for example, if it is within 50 mm, there is no abnormality).

In FIG. 7(B), laser-type digital range finders 149 are placed at predetermined positions (four locations in total, north, south, east, and west) on the upper surface of the lower flange 133 of the restoring support 131, facing upward. Then, the distance between the upper and lower flanges (thickness of the laminated rubber 135) at that position is measured. The measurement timing is the same as the measurement of the horizontal displacement described above. For example, if the average thickness change (displacement/shrinkage) in the north, south, east, and west is within 5 mm, it is determined that there is no abnormality.

FIG. 8 schematically shows the inspector 101 measuring the horizontal displacement of the laminated rubber 135. The inspector 101 is lying on his stomach between the building foundation floor 117 and the underfloor beam 115 in the underground pit of the building. The height dimension between the foundation floor 117 of the building and the lower surface of the underfloor beam 115b is only about 40 cm at the narrowest point. The underground pit has many steel frames with intricate pipes, and there are many steps in the floor and ceiling. In addition, dirt, cobwebs, and fallen leaves have accumulated, and the floor is wet over a wide area during rainy days, creating a hot and humid environment.

The inspector 101 puts on shin pads 107 and elbow pads 105 and, relying on the light from the headlights, kneels or crawls to move to the seismic isolation devices 131, which are located at several locations per building, and We go around it and perform measurement and inspection work. Measuring work is also extremely physically and mentally demanding, as it involves reading millimeter numbers on a ruler in an awkward position. The labor involved in this measurement and inspection work is no mean feat.

Next, inspection and displacement measurement of the sliding bearing type seismic isolation device 231 will be explained with reference to FIG. The sliding bearing 231 shown in this figure is installed on the pile cap to seismically isolate the building in the BSL pile cap seismic isolation method. BSL is an abbreviation for "Ball-point SLider", and in Japanese it is called "sliding bearing with rotating mechanism". This is an excellent technology that can reduce the cost of foundations and building floor structures around seismic isolation devices by absorbing the inclination of pile heads during an earthquake without transmitting it to the sliding surface.

This seismic isolation device 231 includes a member 233 that is installed on the pile cap 211 of a reinforced concrete pile and can swing in two directions with respect to a horizontal plane, and a member 235 that rests on the member 233. What is shown is the outer periphery flange portions of both members, and the inside thereof has a shape (not shown) that fits into the concave and convex portions. A foundation footing (reinforced concrete block) 213 is placed on top of the member 235. A sliding plate 239 coated with low-friction resin is attached to the bottom of the footing 213. Note that the layer 238 schematically shows the gap to be inspected.

The object of displacement measurement of the sliding bearing 231 is the horizontal deviation between the sliding bearing 231 and the sliding plate 239. In FIG. 9, the distance between a predetermined position of the end of the upper member 237 of the sliding bearing 231 (for example, one location on the west side or the north side) and the end of the sliding plate 239 is measured using a ruler 243 (in recent years, a laser distance meter). Measure with. This measurement position is a position specified for a specific seismic isolation device 231, and is marked with a line or the like. Displacement measurements at this fixed location will be performed when the building is completed, five years later, and every 10 years thereafter. Then, the positional deviation is measured and determined (for example, if it is within 50 mm, there is no abnormality).

Preferred modes for carrying out the invention

Embodiments of the present invention will be described below with reference to the drawings.
First, with reference to FIG. 1(A), a situation will be described in which the two-dimensional distance sensor 11 is arranged to face the seismic isolation device 131 and the profile of the measurement target part of the seismic isolation device 131 is acquired. . The meaning of each direction shown in FIG. 1 is as follows. That is, the "back" is the far direction from the distance sensor 11 when looking at the seismic isolation device 131, and the "front" is the near direction. The vertical direction is the earth's gravity direction and the opposite direction. The left-right direction (lateral direction) is the left-right direction when looking at the seismic isolation device 131 from the distance sensor 11.

The seismic isolation device 131 shown in FIG. 1 is a restoring support having the laminated rubber described above with reference to FIG. The restoring support 131 has two flanges 137 made of thick steel plates (see FIG. 1(B)) and a flange 133 bonded to the upper and lower surfaces of a laminated rubber 135. A leg portion 113, which is a block made of reinforced concrete, is placed on top of the upper flange 137, and the lower flange 133 is placed on a reinforced concrete stand 111 (such as a concrete pile cap).

The legs 113 and the stand 111, which are blocks made of reinforced concrete, have a square horizontal shape. A label with a two-dimensional barcode 29, which is an identification mark, is affixed to the outer surface of the leg portion 113. The barcode 29 is pasted on the front side surface 113b and right side surface 113c of the leg portion 113 as far as it can be seen in FIG. 1(A). In this embodiment, if the near side surface 113b is a south facing surface, the barcode 29S of that surface includes the south side identification code. In that case, the right side 113c is the east side and the barcode 29E on that side includes the east side identification code. Although not visible in FIG. 1(A), barcodes 29 are also pasted on other surfaces of the leg portions 113.

On the front side surface 113b of the leg part 113 and the hand side surface 111b of the stand 111, marking marks 113m and 111m are also written for positioning the laser scan beam 21 of the distance sensor (2D-LiDAR), which will be described later. has been done. Note that although not shown in the drawings, the scribing marks are also written on other surfaces of the leg portions 113 and the base 111.

The two-dimensional distance sensor 11 in FIG. 1A is, in this example, known as 2D-LiDAR (Light Detection And Ranging). The distance sensor 11 is fixed at an appropriate height on an upright bar 13 fixed on a trolley 19. A case 17 containing a battery, a transformer, etc. (not shown) is mounted on the trolley 19. FIG. 1A also shows a tablet PC 15 that controls the distance sensor 11 and the like.

FIG. 2 is a block diagram showing an outline of the configuration of the data recording device 10 including the distance sensor 11 and the tablet PC 15 shown in FIG. The distance sensor 11 (sensor unit) includes a 2D-LiDAR 33 which is a distance sensor main body. The 2D-LiDAR 33 itself is a well-known commercially available device, and includes a laser beam emitting/receiving element, a scanning means for the emitted beam, a means for detecting the distance to the beam reflection position, and the like. The sensor unit 11 includes a tilt sensor 31. The tilt sensor 31 detects the tilt angle of the sensor unit 11 and corrects the measured data. That is, the distance data is corrected by the front and rear inclination of the sensor unit 11 (the difference in angle between the laser beam and the ground).

As shown in FIG. 1, the laser beam 21 from the 2D-LiDAR 33 is scanned in a vertical plane and is applied to the seismic isolation device 131 and the legs 113/pedestal 111. The portion hit by the laser beam 21 is visible to the human eye as a red line 23. Adjust the direction of the cart 19 and the distance sensor 11 so that this red line 23 passes through the marking marks 113m and 111m on the front side surface 113b and surface 111b of the leg portion 113 and the stand 111, respectively.

As shown in FIG. 1(B), the height of the distance sensor 11 is set at the middle of the laminated rubber 135 of the seismic isolation device 131 in the vertical direction. Then, the distance sensor 11 measures the distance in the front and back direction of the red line 23 (FIG. 1(A)) where the laser beam 21 hits the seismic isolation device 131. The positions of the lower front edge 137b of the upper flange 137 and the upper front edge 133b of the lower flange 133 are measured by a method described later with reference to FIG. The distance between both edges in the vertical direction is the height of the laminated rubber 135, and the change in the difference in the longitudinal distance between both edges due to an external force such as an earthquake is the horizontal deformation of the laminated rubber 135 due to an external force such as an earthquake.

FIG. 3 is a diagram illustrating an operation for specifying a portion to be measured in dimensions in the profile of the seismic isolation device on the screen of the tablet PC 15 of the data recording device 10 shown in FIG. In Fig. 2, a line 23' representing the profile of the seismic isolation device 131 (a line representing the red line 23 of the part hit by the laser beam 21 on the screen) is a line that extends vertically and bends toward the front and back. It is shown.

That is, from top to bottom, the profile line 23' is a vertical line 113' representing the profile of the front side of the leg 113 ⇒ a horizontal line 113'' representing the profile of the lower surface of the leg 113 ⇒ a profile of the front side of the upper flange 137. Vertical line 137' representing the profile of the lower surface of the upper flange 137 ⇒ Vertical line 135' representing the profile of the front side of the laminated rubber 135 ⇒ Horizontal line 133" representing the profile of the upper surface of the lower flange 133 ⇒ Lower flange 133 Vertical line 133' representing the profile of the front side of table 111⇒Horizontal line 111'' representing the profile of the top surface of table 111⇒Connected with vertical line 111' representing the profile of the front side of table 111.

Regarding this profile line 23', a method of specifying the front lower edge 137b of the upper flange 137 and the front upper edge 133b of the lower flange 133, which are the points to be measured, will be explained. On the screen of the PC, a rectangular frame line 41 (two-dot chain line in FIG. 3) is displayed, for example, as a red line. The position and vertical and horizontal dimensions of this frame line 41 are changed by specifying a range using a pointing device such as a mouse on the screen (or a touch pen, finger, etc. if the screen has a touch function).

In FIG. 3, the frame line 41 (measurement area; area where distance is measured by vertical scanning of the laser beam output from the sensor unit) includes measurement target points 137b' and measurement target points 133b' inside it. Then, adjust the position and size of the frame line 41 so as not to include points C and D (to avoid measuring by mistake). The data recording software installed in the PC recognizes the tip point of the convex edge facing the hand within the frame line 41 as the point to be measured. As a result, the measurement target point 137b' and the measurement target point 133b' are set, and the distance between the two points (edges) in the vertical direction is the height of the laminated rubber 135, and the difference in the distance in the front and rear direction of both edges is the horizontal deformation of the laminated rubber 135. These distances are calculated from distance measurement data from the sensor unit 11. Note that the data recording software can be, for example, driver software that drives the sensor unit 11.

Such measurements are performed in four orthogonal directions within the horizontal plane of the seismic isolation device 131. The measurement data is stored in the storage section of the tablet PC 15. Furthermore, regarding the sliding bearing type seismic isolation device, the X and Y points at the corners of the building frames 213 and 211 shown in Fig. 9 were measured in two orthogonal directions in the horizontal plane using the same method, and the initial value ( The change in the amount of slip in the two directions of the sliding bearing is determined by using the difference between the measured value at the time of handing over the building and the periodic inspection as the displacement.

Note that the data recording device 10 has an imaging device (camera of the tablet PC 15) for reading the two-dimensional barcode 29 and for imaging the work situation at the site. Furthermore, the data recording software installed in the PC includes software for recognizing the photographed two-dimensional barcode 29 and software for processing the photographed site images. The imaging device (camera) does not necessarily need to be included in the data recording device 10, and may instead be a device that has an imaging function, such as a smartphone, to capture images and transfer the acquired image data to the data recording device 10 by wire or wirelessly. .

Next, with reference to FIG. 4, the configuration of a system that outputs the dimensional data of the seismic isolation device recorded on the tablet PC 15 of FIG. 2 as an inspection record file in association with the identification mark 29 will be described. Note that FIG. 4 is a functional block diagram of the system.

On the left side of FIG. 4 is shown a data recording device 10 that is brought to a seismic isolation device inspection site (under the floor of a building, etc.) and records measurement data. The right side of FIG. 4 shows an inspection record creation system 50 located at an inspector's office or the like. The data recording device 10 has been described above with reference to FIG.

In this example, the tablet PC 15 is used as both the data recording device 10 and the inspection record creation system 50. That is, the inspection/measurement data recorded at the site is stored in the tablet PC 15, taken back to the office, etc., and becomes part of the inspection record creation system 50 in the office, etc. Note that the inspection/measurement data stored in the tablet PC 15 may be copied or transferred to the inspection record creation system 50 via an external storage device such as a USB (Universal Serial Bus) memory. It is also possible that inspection/measurement data may be sent from the tablet PCs 15 of many inspectors (contractors) to the inspection record creation system 50 via a mobile phone network or the Internet.

The inspection record creation system 50 includes a cradle 51 on which a tablet PC 15 is placed, a data storage section 53, a PC 55, and the like. The cradle 51, data storage unit 53, and PC 55 may be connected to each other via Ethernet to form a LAN (Local Area Network). When the cradle 51, the data storage section 53, and the PC 55 are connected via Ethernet, the data storage section 53 may be a file system composed of, for example, a file server. The data storage section 53 may be a mass storage such as a hard disk built into the PC 55 or an external hard disk. The data storage unit 53 receives measurement data of the seismic isolation device from the tablet PC 15 via the cradle 51, and stores the same data.

The PC 55 has an original document 57 for each property, a document output software 58, a document import software 61, and a QR code generation tool 65. The original document 57 for each property is an original document in which building information for each property (prefecture, building number, seismic isolation device unique number, seismic isolation type, etc.) is recorded in advance. The form output software 58 generates a form file 57 by adding measurement data of the seismic isolation device to the original form 57 for each property. The form import software 61 generates master data by referring to the original form 57 for each property. The QR code generation tool 65 generates a QR code image for each side of each seismic isolation device 131 in each property. The generated QR code image is made into a QR code panel 69 and provided as a two-dimensional barcode 29.

As mentioned above, the information (property information) of the property (building) handled by this inspection record creation system 50 is recorded in advance in the original form 57, but when the form file 59 is generated by the form output software 58, Measurement information for seismic isolation devices will be added and updated. Note that when the original form 57 for each property is first generated, measurement data at the time of completion is recorded. The property information may include the name and address of the property, the specifications, quantity, identification code, etc. of the installed seismic isolation device. The measurement information of the seismic isolation device includes measurement data at the time of completion of the property described above, as well as measurement data from subsequent periodic inspections.

The form output software 58 acquires property information and measurement information by referring to the original form 57 for each property, adds measurement data recorded on the PC 15, and updates the original form 57 for each property. Outputs 59. The measurement data recorded on the PC 15 may be temporarily recorded in the data storage section 53, or may be directly input into the form output software 58. When measurement data is recorded in the data storage section 53, the form output software 58 acquires the measurement data from the data storage section 53. The form output software 58 outputs the measurement data to a form file 59 in a predetermined form. The contents of the form file 59 can be output on the screen of the PC 55 as a measurement report shown in FIG.

The form import software 61 obtains the original form from the original form 57 for each property, and displays a table of the existing original including the property name etc. on the PC screen.

Next, data linkage between recording software, form output, and form import will be explained. Master data and measurement data are stored in the following folders, for example.
Data folder structure:
Building information master C:\ABData\Master
Measurement data C:\ABData\[Building number]_[Date]

The building information master records building information and is referred to when creating the original document 57 for each property for the first time. The measurement data is recorded for each building and each measurement date, and along with the measurement values, information about the building specified by the QR code, the type of seismic isolation device, and the surface ( direction) is recorded. In addition, the measurement data includes a photographic image of the site at the time of measurement.

Master data usually exists in the tablet PC 15 and the PC 55 that outputs and imports forms. When changing master data (adding a new property, etc.), synchronize (update to the latest data) all master data (C:\ABData\Master). An example of the file structure of master data is shown in FIG.

The QR code generation tool 65 generates a two-dimensional barcode 29 (QR code) for each surface (direction) of the building pillar supported by the seismic isolation device. The generated QR code is printed or otherwise displayed on the QR code panel 69 and pasted on the corresponding side of the corresponding building pillar. The pasted QR code panel 69 is read by a camera provided in the data recording device 10, etc., and input of building information etc. specified by the QR code is automated.
For properties whose seismic isolation devices are newly inspected, a new QR code [New] will be created.

The QR code includes the following information.
(a) Building information; prefecture, building number, etc. (b) Type of seismic isolation device; restoring bearings with laminated rubber, sliding bearings, etc. (c) Direction; north, south, east, west, etc. (d) Version

Next, we will explain how to inspect the seismic isolation device.
(1) First, when constructing a new building, etc., before performing the first measurement of the seismic isolation device, an original document 57 for the property is generated. When referring to building information in generating the original document 57, new building information is registered in the building information master in advance.
(2) Next, a QR code panel 69 is created using the QR code generation tool 65, and the created QR code panel 69 is installed at a predetermined position.

(3) Next, the data recording device 10 is used to perform initial measurements of the seismic isolation device. For newly constructed buildings, the measured values are saved as construction data.
(4) Measure the seismic isolation device at the timing of regular inspections of the target building. In the measurement, the QR code panel 69 is read, the corresponding original document 57 is read out, and the dimensions described in FIGS. 1 to 3 are measured. The measured data is compared with the data from the previous measurement and used to determine whether the test has been passed.

(5) After the measurement is completed, take the data recording device 10 back to the office or the like and generate an inspection report using the inspection record creation system 50. The items to be included in the inspection report are as shown in Figure 5. In addition, "after correction" in Figure 5 is the "temperature correction value", which is based on page 10 of "Maintenance and Management Standards for Seismically Isolated Buildings -2018-" by the Japan Seismic Isolation Structure Association. This is the measured value after correction based on the correction formula.

According to the seismic isolation device inspection system and inspection method described above, report creation is completed almost automatically, so the time required for inspection work and report creation can be significantly shortened. Furthermore, since the sensor can be installed in a narrow space under the floor of a building, the burden of inspection work can be reduced.
