Below, a terminal 10 and a building 1 according to one embodiment of the present invention will be described using Figures 1 to 3.

The terminal 10 is capable of inspecting the amount of filling material 9 used in constructing the partition wall 5 of the building 1 shown in FIG. 1. The building 1 will be described below first.

In this embodiment, the building 1 is constructed of a steel frame. The building 1 has a fire compartment that prevents the fire from spreading in the event of a fire. As shown in FIG. 1, the building 1 has a steel beam 2. The surface of the steel beam 2 is covered with a fireproof coating 3 such as rock wool. A leading piece 4 is fixed to the underside of the steel beam 2. The upper end of a partition wall 5 is fixed to the underside of the leading piece 4.

The partition wall 5 shown in Figures 1 and 2 constitutes a partition of the interior space of the building 1. The partition wall 5 is installed within the fire compartment of the building 1. The partition wall 5 includes a runner 6, a stud 7, and a plasterboard 8.

The runners 6 form the upper and lower ends of the base of the partition wall 5. The runners 6 are formed in a long shape in the width direction of the partition wall 5. As shown in FIG. 1, the upper runner 6 is fixed to the underside of the leading piece 4. The lower runner 6 (not shown) is fixed to the floor slab.

The studs 7, together with the runners 6, form the base of the partition wall 5. The studs 7 are provided between the upper and lower runners 6. The studs 7 are formed in an elongated shape in both the vertical direction.

The gypsum boards 8 form the wall surface of the partition wall 5. The gypsum boards 8 are fixed to the wall base formed by the runners 6 and studs 7. In the example shown in Figure 1, two gypsum boards 8 are provided on each side of the wall base. Note that the example shown in the figure shows an example in which the thickness of the gypsum board 8 on the front side is thinner than the thickness of the gypsum board 8 on the back side (wall base side).

As shown in FIG. 1, a gap S is formed between the upper surface of the gypsum board 8 and the lower surface of the fireproof coating 3 of the steel beam 2. A filler material 9 is filled into the gap S. A gap roughly similar to the gap S is also formed between the lower surface of the gypsum board 8 and the floor slab, and is filled with the filler material 9, but this gap is not shown in the figure.

The filler 9 is made of a fire-resistant material. In this embodiment, the filler 9 is formed by kneading a powdered material mainly composed of gypsum with water. After kneading of the filler 9 is started, heat of hydration is generated by a hydration reaction between the water and the gypsum. The filler 9 hardens when a predetermined time (e.g., one hour) has elapsed after kneading is started. Before hardening, the filler 9 is in a paste form. The filler 9 is filled into the gap S by an operator using an appropriate tool. In this way, a joint that fills the gap S can be formed with the filler 9. By providing the filler 9, fire protection in the gap S can be achieved.

Next, the details of the terminal 10 will be described using Figures 1 and 3.

The terminal 10 is capable of inputting and outputting various types of information, and processing various types of information. As described above, the terminal 10 can be used to inspect whether the amount (volume) of the filler 9 filled in the gap S of the partition wall 5 is appropriate. The terminal 10 may be a portable information terminal (tablet or smartphone). As shown in FIG. 3, the terminal 10 includes a camera unit 11, a memory unit 12, a control unit 13, a touch panel 14, and a communication unit 15.

The camera unit 11 acquires image data captured through a specified lens unit (not shown). The camera unit 11 is capable of acquiring image data of the filling material 9. Here, the image data may be a still image or a video.

In this embodiment, the camera unit 11 is an infrared camera that analyzes infrared rays emitted from the imaging target and visualizes the heat emitted by the imaging target. The camera unit 11 can measure the surface temperature of the filling material 9 and obtain image data indicating the surface temperature as thermography.

The storage unit 12 stores various programs and information such as image data captured by the camera unit 11. The storage unit 12 is composed of a HDD, RAM, ROM, etc.

The control unit 13 executes the programs stored in the memory unit 12. The control unit 13 is configured by a CPU.

The touch panel 14 is capable of inputting and displaying (outputting) various types of information. An inspector (user) inspecting the filling amount can operate the terminal 10 via the touch panel 14. The touch panel 14 can display image data captured by the camera unit 11. The touch panel 14 can also display drawing data showing a floor plan of the building 1 shown in Figure 2. The drawing data shown in Figure 2 shows indications (W1 to W3) showing the specifications of each partition wall 5 of the building 1.

The communication unit 15 transmits and receives various types of information. The communication unit 15 can transmit and receive information to, for example, a terminal other than the terminal 10, a personal computer, an external server, or other control device. Information used for construction and inspection, such as drawing data and construction instructions, can be communicated via the communication unit 15.

The terminal 10 as described above can execute a process (filling amount inspection process) for inspecting whether the amount of filling material 9 is appropriate. The inspection is performed on at least one location of the section where construction using the filling material 9 is performed. The filling amount inspection process executed by the terminal 10 is described below. As shown in FIG. 4, the filling amount inspection process includes a temperature rise amount acquisition process S10, a reference volume calculation process S20, a temperature measurement process S30, a volume estimation process S40, and a judgment process S50.

The temperature rise acquisition process S10 is a process for acquiring the amount of rise in the surface temperature of the test filler (hereinafter referred to as the "test filler 9a"). The test filler 9a is prepared separately from the filler 9 that is actually used for construction (filled into the gap S). The test filler 9a is, for example, of the same type as the filler 9 and has roughly the same quality (water amount per unit volume, etc.). Here, the above-mentioned surface temperature rise refers to the amount of temperature rise above the water temperature used to mix the test filler 9a (filler 9). The temperature rise acquisition process S10 is executed before the worker performs construction to fill the gap S with the filler 9. As shown in FIG. 5, the test filler 9a is placed in an appropriate test container.

In this embodiment, when performing the temperature rise acquisition process S10, information on the "temperature of the water used to mix the test filler 9a" and the "volume of the test filler 9a" is input to the terminal 10. The above information is input in advance by the user's operation. The information on the "temperature of the water used to mix the test filler 9a" may be input by, for example, using the camera unit 11 to measure the temperature of the water used to mix with the test filler 9a, or may be input via the touch panel 14. The information on the "volume of the test filler 9a" is input, for example, via the touch panel 14.

When executing the temperature rise amount acquisition process S10, as shown in FIG. 5, the user aims the camera unit 11 of the terminal 10 at the test filler 9a to capture an image. The temperature rise amount acquisition process S10 is executed by the user through appropriate operations. In the temperature rise amount acquisition process S10, the terminal 10 (control unit 13) acquires image data showing the surface temperature of the test filler 9a from the start of kneading to the end of hardening. The image data may be a video or multiple still images captured at a predetermined interval.

In the temperature rise acquisition process S10, the control unit 13 acquires the temperature rise per unit volume (e.g., 1 ^cm3 or 1 ^m3 ) of the test filler 9a based on the surface temperature (image data) of the filler 9, the "temperature of the water used to knead the test filler 9a," and the "volume of the test filler 9a." The control unit 13 acquires the temperature rise at predetermined time intervals (e.g., 1 second intervals). In the above example, the temperature rise is acquired based on the "temperature of the water used to knead," but instead of this, for example, the "temperature of the test filler 9a immediately after kneading" may be used as the reference.

The reference volume calculation process S20 is a process for acquiring a calculated value obtained by calculating the volume (reference volume) of the filler 9 that is the reference for the amount of filler 9 to be filled into the location (gap S) using the dimensions of the location (gap S). In this embodiment, before the reference volume calculation process S20 is executed, the dimensions of the gap S for calculating the calculated value are input to the terminal 10. Specifically, the apparent dimension (vertical dimension) x1 of the gap S shown in FIG. 1, the filling depth dimension t1 of the gap S, and the width dimension w of the gap S (partition wall 5) shown in FIG. 2 are input to the terminal 10. The above dimensions are input by the user via the touch panel 14, for example.

The apparent dimension x1 of the gap S can be obtained, for example, by the user using a measuring tool such as a convex (scale). The filling depth dimension t1 of the gap S can be obtained, for example, by referring to the thickness dimension of the gypsum board 8. The width dimension w of the gap S can be obtained, for example, from the drawing data of the building 1 (see Figure 2). The width dimension w of the gap S can also be obtained by the user using a measuring tool.

In this embodiment, the control unit 13 calculates the volume of the gap S obtained by multiplying the above dimensions as the reference volume. The reference volume calculation process S20 is executed by an appropriate operation by the user.

The temperature measurement process S30 is a process for measuring the surface temperature of the filler 9 filled in the gap S. The temperature measurement process S30 is executed after the worker fills the gap S with the filler 9 until the filler 9 has finished hardening.

When executing the temperature measurement process S30, as shown in FIG. 1, the user aims the camera unit 11 of the terminal 10 at the filling material 9 to capture an image. The temperature measurement process S30 is executed by the user through appropriate operations. In the temperature measurement process S30, the control unit 13 acquires image data indicating the surface temperature of the filling material 9 at a certain time. The image data may be an image of only a portion of the entire width dimension w of the filling material 9. The control unit 13 also acquires information about the time when the image data was acquired along with the image data.

The volume estimation process S40 is a process for estimating the volume of the filling material 9 based on the image data acquired in the temperature measurement process S30. The volume estimation process S40 may be executed by an appropriate operation by the user, or may be executed automatically after the temperature measurement process S30 is executed.

In this embodiment, before the volume estimation process S40 is executed, information on the "temperature of the water used to mix the filler 9" and the "time when mixing of the filler 9 started" is input to the terminal 10. The above information is input in advance by the user's operation. The information on the "temperature of the water used to mix the filler 9" may be input by, for example, using the camera unit 11 to measure the temperature of the water used to mix with the filler 9, or may be input via the touch panel 14. The information on the "time when mixing of the filler 9 started" is input, for example, via the touch panel 14.

In the volume estimation process S40, the control unit 13 calculates the amount of rise in the surface temperature of the filler 9 after a first time (e.g., 30 minutes) has elapsed since the start of kneading, based on the surface temperature (image data) of the filler 9, the "temperature of the water used to knead the filler 9," and the "time when kneading of the filler 9 began." Note that in the above example, the amount of rise in the surface temperature is obtained based on the "temperature of the water used to knead," but instead of this, for example, the "temperature of the filler 9 immediately after kneading" may be used as the reference.

The control unit 13 also calculates an estimate of the volume of the filler 9 based on the amount of rise in the surface temperature of the filler 9 after the first time has elapsed and the amount of temperature rise acquired in the temperature rise acquisition process S10 at a time point when the same time as the first time has elapsed (e.g., 30 minutes). The estimate of the filling amount of the filler 9 is calculated from the relationship between the "volume of the test filler 9a" and the "amount of rise in the surface temperature" (amount of temperature rise per unit volume of the test filler 9a) that has been previously determined based on the information acquired in the temperature rise acquisition process S10. Note that when calculating the estimate of the filling amount of the filler 9, the estimate may be corrected using an appropriate correction value.

The judgment process S50 is a process for judging whether or not the volume (estimated value) of the filling material 9 estimated in the volume estimation process S40 is within a predetermined allowable range. The judgment process S50 may be executed by an appropriate operation by the user, or may be executed automatically after the volume estimation process S40 is executed.

The above-mentioned allowable range is set based on the calculated value of the reference volume calculated in the reference volume calculation process S20. Specifically, the lower limit of the allowable range is the calculated value - a predetermined value α, and the upper limit of the allowable range is the calculated value + a predetermined value α. The above-mentioned predetermined value α can be set to any value.

If the estimated value of the volume estimation process S40 is within the allowable range (above the lower limit and below the upper limit), the control unit 13 makes a pass judgment. If the estimated value is outside the allowable range, the control unit 13 makes a fail judgment. If the estimated value is within the allowable range, it is estimated that the filler 9 has been filled into almost the entire area (gap S) where the filler 9 is to be filled. In other words, it is estimated that the amount of filler 9 filled is sufficient. The judgment result is displayed on the touch panel 14. The judgment result is also stored in the memory unit 12.

According to the above-described filling amount inspection process, the volume of the filler 9 can be estimated based on image data showing the surface temperature of the filler 9. This makes it possible to easily estimate the volume of the filler 9, unlike a method in which the volume of the filler 9 is estimated by, for example, measuring the weight of the container that contained the filler 9 before and after use of the filler 9.

In addition, the filling amount inspection process makes it easy to determine whether the amount of filling material 9 is sufficient. This reduces the effort required for the user to inspect the amount of filling material 9.

In addition, in this embodiment, as shown in FIG. 2, the inspection result of the filling amount of the filler 9 can be recorded using the drawing data displayed on the touch panel 14 of the terminal 10. In this case, when performing the inspection, the user displays the drawing data on the touch panel 14 and inputs which partition wall 5 to inspect by appropriate operations. In this embodiment, when the filling amount inspection process is performed, the control unit 13 changes the color of the display (W2 in the figure) showing the specifications of the inspected partition wall 5. In this way, by visualizing whether or not the partition wall 5 has been inspected, the inspection status can be easily confirmed. In addition, the control unit 13 can execute an appropriate notification (alert) when, for example, there is an omission or defect in the inspection location in the drawing data.

The control unit 13 can also display the judgment results of the judgment process S50 on the drawing data. For example, the control unit 13 can execute a process of color-coding the display color indicating the specifications of the partition wall 5 so that the pass/fail judgment result can be distinguished. This makes it easy to check the inspection results.

In this way, by recording the inspection status and results using the drawing data displayed on the touch panel 14 of the terminal 10, there is no need to print out the drawings using a printer or the like, making it possible to go paperless. In addition, by using the terminal 10, even if there are changes to the drawing data, construction instructions, etc., the latest information can be obtained via the communication unit 15.

The control unit 13 can also communicate information about the drawing data displaying the inspection status and inspection results as described above with a terminal other than the terminal 10, a personal computer, an external server, etc., via the communication unit 15. This allows information about the inspection status and inspection results to be shared with third parties.

Note that the above-described filling amount inspection process (temperature rise amount acquisition process S10, reference volume calculation process S20, temperature measurement process S30, volume estimation process S40, and judgment process S50) is an example, and the processes executed by the terminal 10 are not limited to the above-described examples.

For example, in the volume estimation process S40, the control unit 13 may correct the estimated value of the filling amount of the filler 9 using an appropriate correction model created by machine learning. Here, machine learning refers to analyzing accumulated learning data (learning data) and creating a model that learns the pattern of feature amounts (quantitatively indicating the features (characteristics) of data extracted from the learning data) extracted from the learning data to enable appropriate processing. As a machine learning method, various methods such as a decision tree, a neural network, and a random forest can be adopted.

When creating a correction model, for example, the "actual value data" of the volume of the filler 9, the "estimated value data" calculated in the volume estimation process S40, and other data related to the construction are accumulated as learning data. The "actual value data" can be measured, for example, by measuring the weight of the container containing the filler 9 before and after use of the filler 9. This makes it possible to create a correction model by learning the relationship (error) between the estimated value and the actual value using machine learning using the learning data. Specifically, for example, it is possible to extract factors that are estimated to be the cause of the error from the "other construction data" and create a correction model that can correct the error.

As the "other construction data" of the learning data, various information can be used, such as the quality of the filler 9 (e.g., the amount of water per unit volume and viscosity), the type of filler 9, air temperature, the temperature of the filling point, the time elapsed since the start of mixing, etc. Each of the above information can be obtained from past construction sites or tests. When each of the above information is used as learning data, when executing the volume estimation process S40, each of the information obtained at the construction site of the building 1 (each of the information corresponding to the learning data) is input to the terminal 10 as input data. This makes it possible to correct the estimated value of the filling amount based on the input data and the learning data.

The correction model is created before the filling amount inspection process is executed (for example, at a past construction site or in a test). The correction model may be created using the terminal 10, or may be created using a terminal other than the terminal 10, a personal computer, etc.

By using the correction model, it is possible to perform a correction based on machine learning on the estimated value of the filling amount of the filler 9 calculated by the volume estimation process S40. This makes it possible to further improve the accuracy of the estimated value of the volume estimation process S40.

In addition, the manner of correction using the correction model is not limited to the above example. For example, in the standard volume calculation process S20, the calculated value of the standard volume of the filler 9 may be corrected using the correction model. That is, in the standard volume calculation process S20 described above, the standard volume of the filler 9 (the volume of the gap S) is calculated on the assumption that the apparent dimension x1 of the gap S is constant throughout the entire width direction. However, since the lower surface of the fireproof coating 3 shown in FIG. 1 is considered to have an uneven shape, it is considered that there is a certain degree of error between the calculation result of the standard volume of the filler 9 using the apparent dimension x1 and the volume of the filler 9 actually filled.

For example, the "image of the underside of the fireproof coating 3" included in the image data of the filler 9 may be stored as learning data, and the relationship (error) with the "actual volume of the filler 9" may be learned by machine learning to create a correction model. The "actual volume of the filler 9" may be measured, for example, at a past construction site, by measuring the weight of the container containing the filler 9 before and after its use. In this way, by using the correction model in the reference volume calculation process S20, the accuracy of the calculation value of the reference volume of the filler 9 in the reference volume calculation process S20 can be further improved.

As described above, the volume estimation device (terminal 10) according to the first embodiment of the present invention:
A temperature measuring unit (control unit 13) capable of measuring the surface temperature of the sealing material (filler 9) that generates heat in a usable state (from the start of kneading to the completion of hardening) when the sealing material (filler 9) is used in the use location (gap S);

In other words, since the volume of the sealing material (filler 9) is estimated based on the measured value of the surface temperature of the sealing material (filler 9), the volume of the sealing material (filler 9) used can be easily estimated, unlike a method that measures the difference in weight of a container of the sealing material (filler 9) before and after use.

It is equipped with the following.

This configuration makes it easy to inspect the sealing material (filler 9) used in the location of use (gap S). In other words, using the reference volume calculated by the reference volume calculation unit and the estimated volume of the sealing material (filler 9) by the volume estimation unit (control unit 13), it is easy to inspect whether the amount of sealing material (filler 9) used in the location of use (gap S) is sufficient.

In addition, the reference volume calculation unit (control unit 13)
The reference volume is calculated based on the dimensions of the location of use (gap S).

With this configuration, the reference volume of the sealing material (filler 9) can be easily calculated using the dimensions of the area of use (gap S).

In addition, the volume estimation device (terminal 10)
An imaging unit (camera unit 11) for imaging the sealing material (filler 9),
The temperature measurement unit (control unit 13)

Further, the volume estimation method according to the first embodiment of the present invention includes:
A temperature measurement process (temperature measurement process S30) for measuring the surface temperature of the sealing material (filler 9) that generates heat in a usable state (from the start of kneading to the completion of hardening) while the sealing material (filler 9) is used in the use location (gap S);
a volume estimation step (volume estimation process S40) of estimating a volume of the sealing material (filler 9) based on a measured value of the surface temperature measured in the temperature measurement step (temperature measurement process S30);
It is equipped with the following.

This configuration makes it easy to estimate the volume of the sealing material (filler 9) used in the area of use (gap S).

The volume estimation method is as follows:
A temperature rise amount acquisition process (temperature rise amount acquisition process S10) is provided for acquiring a temperature rise amount per unit volume of a test sealing material (filler 9) prepared separately from the sealing material (filler 9),
In the volume estimation step (volume estimation process S40),
The volume of the sealing material (filler 9) is estimated based on the temperature rise of the surface temperature per unit volume acquired in the temperature rise acquisition process (temperature rise acquisition process S10) and the measured value of the surface temperature measured in the temperature measurement process (temperature measurement process S30).

For example, the terminal 10 can execute the filling amount inspection process according to the second embodiment shown in FIG. 6 and FIG. 7.

Note that in the following description, points similar to the filling amount inspection process according to the first embodiment will be omitted as appropriate.

In this embodiment, the partition wall 5A that is the subject of inspection in the filling amount inspection process is different from the partition wall 5 in the first embodiment.

In addition, in the partition wall 5A, no gap S is formed between the upper surface of the gypsum board 8 and the lower surface of the fire-resistant coating 3 of the steel beam 2, and a filler 9A is filled in the recessed corner between the lower surface of the fire-resistant coating 3 and the gypsum board 8. The filler 9A is provided in a generally triangular shape (triangular seal shape) in cross section. In the example shown, the angle of the inclined surface of the filler 9A facing diagonally downward is approximately 45 degrees with respect to the up-down direction (vertical direction). The filler 9A is provided on both sides of the partition wall 5.

Below, as shown in FIG. 7, the processing executed by the terminal 10 in the filling amount inspection processing according to the second embodiment will be described. The filling amount inspection processing according to the second embodiment differs from the filling amount inspection processing according to the first embodiment shown in FIG. 4 mainly in the aspect of the reference volume calculation processing S20A.

The temperature rise amount acquisition process S10 is generally similar to the process shown in FIG. 4. Therefore, a description of the temperature rise amount acquisition process S10 will be omitted.

The reference volume calculation process S20A is a process for obtaining a calculated value of the reference volume of the filler 9A using image data of the filler 9A. In this embodiment, the reference volume calculation process S20A calculates the reference volume of the filler 9A without measuring the dimensions (visible dimensions and filling depth dimensions) using a measuring tool.

When executing the reference volume calculation process S20A, as shown in FIG. 6, the user aims the camera unit 11 of the terminal 10 at the filler 9A to capture an image and obtain image data. The reference volume calculation process S20A is executed by an appropriate operation by the user. When capturing an image of the filler 9A, as shown in FIG. 6, the terminal 10 is tilted so that the surface on which the camera unit 11 is provided faces diagonally upward toward where the filler 9A is located.

In the reference volume calculation process S20A, the control unit 13 acquires information on the inclination of the terminal 10 when the image of the filling material 9A is captured. The above-mentioned inclination information can be acquired by a tilt sensor (e.g., a gyro sensor, etc.) provided in the terminal 10. The tilt sensor detects the inclination of the terminal 10 with respect to a predetermined reference direction. For example, as shown in FIG. 6, the tilt sensor detects the inclination angle θ of the surface on which the camera unit 11 of the terminal 10 is provided with respect to the reference direction (vertical direction).

In the reference volume calculation process S20A, the control unit 13 calculates the reference volume of the filler 9A using the image data and the tilt angle θ. Specifically, as shown in FIG. 6, the user tilts the terminal 10 so that the surface on which the camera unit 11 of the terminal 10 is provided is roughly parallel to the inclined surface of the filler 9A, and captures an image of the filler 9A. In this case, the tilt angle of the inclined surface of the filler 9A relative to the vertical direction roughly coincides with the tilt angle θ detected by the tilt sensor.

The control unit 13 also acquires the width dimension x2 of the inclined surface of the filler 9A based on the image data. The width dimension x2 can be calculated based on an appropriate reference image included in the image data, the distance between the camera unit 11 and the filler 9A, etc. The distance between the camera unit 11 and the filler 9A can be acquired using an appropriate distance meter provided in the terminal 10. The control unit 13 can calculate the dimensions (vertical and horizontal dimensions) of the other two sides of the filler 9A, which is triangular in cross section, based on the width dimension x2 of the inclined surface of the filler 9A. At this time, the control unit 13 acquires the vertical dimension of the filler 9A as the apparent dimension x2'.

In this embodiment, the control unit 13 uses the dimensions of the filler 9A, which has a triangular cross-sectional shape, to calculate the dimensions of a virtual filler 9A', which has a rectangular cross-sectional shape like a typical joint, and then calculates the reference volume of the filler 9A using the dimensions of the filler 9A'.

Specifically, the control unit 13 first calculates the cross-sectional area of the filler 9A from the dimensions of two sides of the filler 9A in a cross-sectional view. Next, as shown in FIG. 6, the control unit 13 uses the cross-sectional area of the triangular filler 9A to calculate the dimensions of a virtual filler 9A' that has the same cross-sectional area as the filler 9A and has a vertical dimension of a rectangular shape x2' in a cross-sectional view. The control unit 13 calculates the filling depth dimension t2 of the filler 9A' from the cross-sectional area and the vertical dimension x2'.

Next, the control unit 13 calculates the reference volume of the filler 9A' (filler 9A) by multiplying the apparent dimension x2', the filling depth dimension t2, and the width dimension w of the filler 9A' in the same manner as in the reference volume calculation process S20 according to the first embodiment. At this time, the user inputs the width dimension w of the filler 9A into the terminal 10. Note that the width dimension w may be obtained from the drawing data of the building 1 (see FIG. 2) as in the first embodiment, or may be obtained by the user by measuring using a measuring tool.

The temperature measurement process S30 is generally similar to the process shown in FIG. 4. In this embodiment, the temperature measurement process S30 can be executed using the image data acquired in the reference volume calculation process S20A.

The volume estimation process S40 and the determination process S50 are generally similar to the processes shown in FIG. 4. That is, the control unit 13 determines whether the volume (estimated value) of the filler 9A estimated in the volume estimation process S40 is within a predetermined allowable range, based on the calculated value of the reference volume calculated in the reference volume calculation process S20A.

The fill amount detection process according to the second embodiment described above also provides substantially the same effects as the first embodiment.

In addition, the filling amount detection process according to the second embodiment makes it possible to estimate the volume of the filling material 9A without measuring the dimensions (visible dimensions and filling depth dimensions) using a measuring tool.

As described above, the volume estimation device (terminal 10) according to the second embodiment of the present invention has the following features:
An imaging unit (camera unit 11) for imaging the sealing material (filler 9),
The reference volume calculation unit is
The reference volume is calculated based on image data captured by the imaging section (camera section 11).

This configuration makes it easy to calculate the reference volume of the sealing material (filler 9). In other words, the reference volume of the sealing material (filler 9) can be calculated based on image data without measuring the dimensions of the area of use (gap S) with a measuring tool.

Furthermore, the present invention is not limited to the above-described embodiments. For example, the terminal 10 can execute the filling amount inspection process according to the third embodiment shown in FIG. 8 and FIG. 9. The filling amount inspection process according to the third embodiment will be described below. Note that in the following description, points similar to those in the filling amount inspection process according to the first and second embodiments will be omitted as appropriate.

In this embodiment, the partition wall 5B that is the subject of the filling amount inspection process is different from the partition wall 5 in the first embodiment.

The partition wall 5B shown in FIG. 8 differs from the above-mentioned embodiments in that two gypsum boards 8 are provided on one side of the wall base (runners 6 and studs 7). In the partition wall 5B, a gap S is formed between the upper surface of the gypsum board 8 and the underside of the fire-resistant coating 3 of the steel beam 2. The partition wall 5B is filled so that it is located in the inside corner between the gap S and the underside of the fire-resistant coating 3 and the gypsum board 8.

The portion of the filler 9B that fills the gap S is generally similar to the filler 9 according to the first embodiment shown in FIG. 1. Therefore, in the following explanation, this portion will be described as the filler 9. Also, the portion of the filler 9B that fills the inside corner between the underside of the fireproof coating 3 and the gypsum board 8 (behind the filler 9) is generally similar to the filler 9A according to the second embodiment shown in FIG. 6. Therefore, in the following explanation, this portion will be described as the filler 9A.

Below, we will explain the processing executed by the terminal 10 in the filling amount inspection processing according to the third embodiment, as shown in Figure 9.

The temperature rise amount acquisition process S10 is generally similar to the process shown in FIG. 4 (FIG. 7). Therefore, a description of the temperature rise amount acquisition process S10 will be omitted.

The reference volume calculation process S20B is a process for obtaining the sum of the reference volumes of the filler 9 and the filler 9A as the calculated value of the reference volume of the filler 9B. The method for calculating the reference volume of the filler 9 is the same as the reference volume calculation process S20 according to the first embodiment. The method for calculating the reference volume of the filler 9A is the same as the reference volume calculation process S20A according to the second embodiment. The control unit 13 obtains the calculated value of the reference volume of the filler 9B by adding the reference volumes of the filler 9 and the filler 9A.

The temperature measurement process S30 is generally similar to the process shown in FIG. 4 (FIG. 7). In this embodiment, the control unit 13 acquires the surface temperature of the filler 9B using the image data acquired for calculating the volume of the filler 9A in the reference volume calculation process S20B.

The volume estimation process S40 is generally similar to the process shown in FIG. 4 (FIG. 7). In this embodiment, the control unit 13 calculates an estimate of the volume of the filler 9B based on the surface temperature of the filler 9B acquired in the temperature measurement process S30.

The determination process S50 is generally similar to the process shown in FIG. 4 (FIG. 7). In this embodiment, the control unit 13 determines whether the volume (estimated value) of the filler 9B estimated in the volume estimation process S40 is within a predetermined allowable range, based on the calculated value of the reference volume calculated in the reference volume calculation process S20B.

The fill amount detection process according to the third embodiment described above also provides substantially the same effects as the previous embodiments.

Although each embodiment of the present invention has been described above, the present invention is not limited to the above configurations, and various modifications are possible within the scope of the invention described in the claims.

For example, in each of the above embodiments, an example is shown in which the camera unit 11 of the terminal 10 is used to acquire image data of the filler 9 (filler 9A, filler 9B), but this is not limited to this form. For example, the image data may be acquired using an appropriate camera device (infrared camera) different from the terminal 10. In this case, the image data acquired by the camera device can be transmitted to the terminal 10 to execute the filling amount inspection process. Note that in this case, the filling amount inspection process can also be executed by a control device such as a general personal computer or an external server instead of the terminal 10.

In addition, in each of the above embodiments, an example was shown in which the surface temperature of the filler 9 (filler 9A, filler 9B) was measured by the camera unit 11, but this configuration is not limited to this. For example, the surface temperature of the filler 9 (filler 9A, filler 9B) may be measured using an appropriate non-contact thermometer (temperature sensor). In this case, the camera unit 11 of the terminal 10 may be a camera that captures images using normal visible light, rather than an infrared camera.

In addition, in each of the above embodiments, the filler 9 (filler 9A, filler 9B) is mainly composed of gypsum, but the present invention is not limited to such a configuration, and various fillers that generate heat when in a usable state, such as cement paste or mortar, can be used as the filler 9 (filler 9A, filler 9B).

In addition, in each of the above embodiments, the sealing material is the filler 9 (filler 9A, filler 9B) that is filled in the filling portion of the partition wall 5 (partition wall 5A), but the present invention is not limited to this configuration, and sealing materials that are used in various locations can be used as the sealing material.
