Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above tapping inspection, there is a problem that the adhesion state may be judged to be good even though the actual adhesion state of the exterior material is poor.

[0005] As a result of intensive research, the inventors have found that the causes of adhesion failure associated with the aging deterioration of the exterior material include not only those associated with the peeling of the exterior material and the adhesive, but also those associated with frost damage. The adhesion failure associated with frost damage is caused by moisture infiltrating into the wall base for some reason, and the moisture expanding when frozen, thereby reducing the adhesive force between the adhesive and the wall base.

[0006] Adhesion failure due to peeling can be determined by impact sound inspection, but adhesion failure due to freezing damage cannot be determined by impact sound inspection. Therefore, there was still room for further improvement in improving the diagnostic accuracy of the adhesion state.

[0007] The present invention has been devised in view of the above actual situation, and the main object is to provide a method capable of diagnosing the adhesion state of the exterior material with high accuracy.

[0010] In the method for diagnosing the outer wall according to the present invention, in the first determination step, when the moisture content is greater than a predetermined threshold value, it may be determined that the adhesion state is poor.

[0011] In the method for diagnosing the outer wall according to the present invention, the threshold value may be determined in advance according to the type of material of the wall base.

[0012] The method for diagnosing the outer wall according to the present invention may further include a step of performing a destructive inspection on the exterior material determined to have a poor adhesion state.

[0013] In the method for diagnosing the outer wall according to the present invention, prior to the moisture content measurement step, it further includes a second determination step of diagnosing whether the adhesion state is good or bad based on the impact sound generated by tapping the outer surface of the exterior material, and the moisture content measurement step may be executed when it is determined that the adhesion state is good in the second determination step.

[0014] In the method for diagnosing the outer wall according to the present invention, the wall base is composed of a plurality of wall panels arranged side by side, and in the moisture content measurement step, the moisture content is measured for each of the plurality of wall panels. In the first determination step, the quality of the adhesion state may be determined for each of the plurality of wall panels.

[0015] The present invention relates to a diagnostic device for an outer wall having a wall base and a finishing material fixed to the wall base with an adhesive, including a moisture content measurement unit for measuring the moisture content of the wall base, a moisture content storage unit for inputting the measurement result of the moisture content, a first determination unit for determining the quality of the adhesion state of the finishing material based on the moisture content, and a display unit for displaying the determination result of the adhesion state.

[0016] The method for diagnosing an outer wall according to the present invention is characterized by including a step of repairing a finishing material determined to have a poor adhesion state in the method for diagnosing an outer wall according to any one of the above.

Embodiments for Carrying Out the Invention

[0019] Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be understood that the drawings include exaggerated expressions and expressions different from the dimensional ratios of actual structures in order to assist in understanding the content of the invention. Also, throughout each embodiment, the same or common elements are denoted by the same reference numerals, and duplicate explanations are omitted. Furthermore, the specific configurations shown in the embodiments and the drawings are for understanding the content of the present invention, and the present invention is not limited to the specific configurations shown.

[0020] [Outer wall] FIG. 1 is a perspective view showing an outer wall 1 diagnosed by the outer wall diagnosis method (hereinafter sometimes simply referred to as the “diagnosis method”) of the present embodiment. FIG. 2 is a cross-sectional view of FIG. 1. The outer wall 1 of the present embodiment is formed on a building such as a general house or building. The outer wall 1 of the present embodiment has a wall base 2 and a finishing material 3.

[0021] [Wall base] The wall base 2 of the present embodiment is configured, for example, by arranging a plurality of wall panels 2P, 2P. The plurality of wall panels 2P, 2P are formed, for example, in a rectangular plate shape and are fixed to a frame body (not shown) etc. (omitted in the drawing). For each wall panel 2P, for example, a ceramic siding material, ALC (lightweight cellular concrete), calcium silicate board, gypsum board, or gypsum slag board etc. can be adopted.

[0022] A gap 4 (for example, about 3 to 30 mm) is provided between adjacent wall panels 2P, 2P of the present embodiment. The gap 4 is filled with a sealing material 5. For the sealing material 5, for example, silicone-based, modified silicone-based, urethane-based, acrylic-based, polysulfide-based, or acrylic urethane-based etc. can be appropriately adopted.

[0023] [Finishing material] The finishing material 3 of the present embodiment is fixed to the wall base 2 with an adhesive 6. For the adhesive 6 of the present embodiment, for example, an elastic adhesive or mortar etc. is used.

[0024] The exterior material 3 of this embodiment is configured as, for example, a plurality of tiles 7, but is not particularly limited. The exterior material 3 may be configured of, for example, stone materials, ceramic plates, or the like. The plurality of tiles 7 of this embodiment are arranged in, for example, a checkered pattern, but may be arranged in a herringbone pattern or the like. A joint 8 (for example, about 3 to 8 mm) is provided between adjacent tiles 7, 7. The joint bottom of the joint 8 of this embodiment is composed of a cured product of the adhesive 6.

[0025] By the way, in the outer wall 1 as described above, in order to maintain the state where the exterior material 3 is fixed to the wall base 2, it is important to periodically diagnose the adhesion state of the exterior material 3 and repair the exterior material 3 determined to have a poor adhesion state.

[0026] Generally, for the diagnosis of the adhesion state of the exterior material 3, for example, as in Patent Document 1, a tapping sound inspection for diagnosing the quality of the adhesion state is carried out based on the tapping sound generated by tapping the outer surface 3o of the exterior material 3. In such a tapping sound inspection, different tapping sounds are generated between the portion where the exterior material 3 and the adhesive 6 are adhered and the portion where the exterior material 3 and the adhesive 6 are peeled off, so it is possible to determine the adhesion failure associated with the peeling of the exterior material 3 and the adhesive 6. However, in the tapping sound inspection, there is a problem that in some cases, although the actual adhesion state of the exterior material 3 is poor, it is determined that the adhesion state is good.

[0027] As a result of intensive research, the inventors have found that the causes of adhesion failure associated with the aging deterioration of the exterior material 3 include not only those associated with the peeling of the exterior material 3 and the adhesive 6 but also those associated with freezing damage.

[0028] Adhesion failure due to freezing damage occurs when moisture infiltrates the wall base 2 for some reason (e.g., through through-holes such as screws fixed to the outer wall 1), and the moisture expands upon freezing, reducing the adhesive force between the adhesive 6 and the wall base 2. In a portion where such adhesion failure due to freezing damage has occurred, even though the adhesive force between the adhesive 6 and the wall base 2 has decreased, if the exterior material 3 and the adhesive 6 are adhered, a good tapping sound will be generated in the tapping sound inspection. Therefore, it is difficult to determine adhesion failure due to freezing damage through the tapping sound inspection.

[0029] As a result of further research, the inventors found that there is a certain correlation between the moisture content of the wall base 2 and the adhesion failure of the exterior material 3 due to freezing damage. In the diagnostic method of the present embodiment, the adhesion state of the exterior material 3 is diagnosed based on the moisture content of the wall base 2.

[0030] [Diagnostic device for outer wall] In the diagnostic method of the present embodiment, a diagnostic device 10 for the outer wall 1 (hereinafter sometimes simply referred to as the "diagnostic device") is used. FIG. 3 is a block diagram showing the diagnostic device 10 for the outer wall of the present embodiment.

[0031] The diagnostic device 10 of the present embodiment includes a moisture content measurement unit 11, a moisture content storage unit 18A, and a first determination unit 19A. Further, the diagnostic device 10 of the present embodiment includes a determination result storage unit 18B. In the present embodiment, the moisture content storage unit 18A, the first determination unit 19A, and the determination result storage unit 18B are configured by a computer 10A. The computer 10A is configured by, for example, a personal computer, a portable information terminal (such as a tablet type), and a cloud server connected via the Internet.

[0032] The diagnostic device 10 (computer 10A) of the present embodiment has an input unit 12, an output unit 13, and an arithmetic processing unit 14.

[0033] The input unit 12 is for inputting information (such as characters) to the arithmetic processing unit 14. For this input unit 12, for example, a keyboard, a mouse, or a touch panel, etc. is used.

[0034] The output unit 13 is for outputting information from the arithmetic processing unit 14. For the output unit 13, for example, a display device or a printer, etc. is used.

[0035] The arithmetic processing unit 14 includes an arithmetic unit (CPU) 15 that performs various operations, a storage unit 16 in which data, programs, etc. are stored, and a working memory 17.

[0036] The storage unit 16 is a non-volatile information storage device composed of, for example, a magnetic disk, an optical disk, an SSD, or a flash memory, etc. The storage unit 16 is configured to include a data unit 18 and a program unit 19.

[0037] The data unit 18 is for storing information necessary for diagnosing the outer wall 1, etc. The data unit 18 of the present embodiment includes the above-mentioned moisture content storage unit 18A, determination result storage unit 18B, and threshold value storage unit 18C.

[0038] The moisture content storage unit 18A of the present embodiment is for inputting the measurement result of the moisture content of the wall base 2. The determination result storage unit 18B of the present embodiment is for inputting the determination result of the adhesion state of the exterior material 3. The threshold value storage unit 18C of the present embodiment is for inputting the threshold value used for determining the quality of the adhesion state of the exterior material 3.

[0039] The program unit 19 is a program for causing the arithmetic unit 15 to execute the determination method of the present embodiment. The program unit 19 of the present embodiment includes a first determination unit 19A and a display unit 19B. The first determination unit 19A of the present embodiment is for determining the quality of the adhesion state of the exterior material 3 based on the moisture content. The display unit 19B of the present embodiment is for displaying the determination result of the adhesion state.

[0040] As shown in FIGS. 1 and 2, the moisture content measurement unit 11 is for measuring the moisture content of the wall base 2. The moisture content measurement unit 11 is not particularly limited as long as it can measure the moisture content of the wall base 2. For the moisture content measurement unit 11, for example, an electric resistance type moisture meter or a high frequency type moisture meter is used. An electric resistance type moisture meter is adopted for the moisture content measurement unit 11 of the present embodiment.

[0041] The moisture content measurement unit 11 of the present embodiment includes a housing 21, a pair of electrodes (needles) 22, 22 for contacting the measurement object, an operation unit 23 for operating the start and stop of the measurement, etc., and a result display unit 24 for displaying the measurement result. In the present embodiment, the measurement result of the moisture content is input from the input unit 12 shown in FIG. 3 to the moisture content storage unit 18A by an inspection person or the like, but it is not limited to such a mode. For example, by communicably connecting the moisture content measurement unit 11 and the computer 10A, the measurement result may be automatically input to the moisture content storage unit 18A.

[0042] [Diagnosis method for outer wall (First Embodiment)] Next, the processing procedure of the diagnosis method of the present embodiment will be described. FIG. 4 is a flowchart showing the processing procedures of the outer wall diagnosis method and the outer wall repair method of the present embodiment.

[0043] [Second determination step] In the diagnosis method of the present embodiment, first, based on the tapping sound generated by tapping the outer surface 3o of the exterior material 3 shown in FIGS. 1 and 2, the quality of the adhesion state is diagnosed (second determination step S1). In the second determination step S1 of the present embodiment, first, a tapping sound inspection of the exterior material 3 is performed in the same procedure as the conventional tapping sound inspection. In the tapping sound inspection of the present embodiment, it is performed by the sensory evaluation of the inspection person based on the tapping sound generated by tapping the outer surface 3o with a known percussion hammer (not shown), but for example, a tapping sound inspection device described in Patent Document 1 may be used.

[0044] In the second determination step S1 of the present embodiment, it is desirable to perform a tapping sound inspection on all the exterior materials 3 (a plurality of tiles 7) constituting the outer wall 1. Thereby, in the second determination step S1, it is possible to surely identify the exterior material 3 that has peeled off from the adhesive 6.

[0045] In the present embodiment, when it is determined that the adhesion state of the exterior material 3 is good (''good'' in the second determination step S1), the moisture content measurement step S2 is carried out. On the other hand, when it is determined that the adhesion state of the exterior material 3 is bad (''bad'' in the second determination step S1), the exterior material 3 is repaired (step S5) in the method for repairing the outer wall 1 described later.

[0046] [Measure the moisture content of the wall base] Next, in the diagnostic method of the present embodiment, the moisture content of the wall base 2 is measured (moisture content measurement step S2). The measurement procedure is not particularly limited as long as the moisture content of the wall base 2 can be measured. In the moisture content measurement step S2 of the present embodiment, a pair of electrodes 22, 22 of the moisture content measurement unit 11 are passed through the adhesive 6 exposed from the joint 8, and the pair of electrodes 22, 22 are brought into contact with the outer surface 2o of the wall base 2. Thereby, the moisture content of the wall base 2 is measured.

[0047] In the present embodiment, since the moisture content of the wall base 2 can be measured only by passing a pair of electrodes 22, 22 through the adhesive 6, for example, it is not necessary to peel off the tile 7 fixed with the adhesive 6. Thereby, in the present embodiment, the moisture content can be measured quickly. Further, in the present embodiment, since the damage to the adhesive 6 due to the penetration of the pair of electrodes 22, 22 can be minimized, the repair of the adhesive 6 can be carried out quickly after the moisture content measurement.

[0048] The measurement location of the moisture content of the wall base 2 is set as appropriate. As shown in FIG. 1, the wall base 2 of the present embodiment is configured by arranging a plurality of wall panels 2P, 2P. Generally, the moisture that has penetrated into the wall panel 2P spreads over the entire wall panel 2P, and the moisture content tends to approach uniformity over the entire wall panel 2P.

[0049] In addition, since a gap 4 (sealing material 5) is provided between adjacent wall panels 2P, 2P, moisture that has penetrated into one wall panel 2P does not move to the other wall panel 2P. Therefore, in the moisture content measurement step S2 of the present embodiment, the moisture content is measured for each of the plurality of wall panels 2P. As a result, in the moisture content measurement step S2 of the present embodiment, it is possible to efficiently measure the overall moisture content of the wall base 2.

[0050] The measurement location of the moisture content of each wall panel 2P can be set as appropriate. As described above, since the moisture content tends to approach uniformity throughout each wall panel 2P, it is desirable to measure the moisture content at at least one location on each wall panel 2P.

[0051] In the moisture content measurement step S2 of the present embodiment, the measurement result of the moisture content is input from the input unit 12 shown in FIG. 1 into the moisture content storage unit 18A by an inspector or the like. When the moisture content measurement unit 11 and the computer 10A can be connected, the measurement result may be automatically input into the moisture content storage unit 18A.

[0052] [First determination step] Next, in the diagnosis method of the present embodiment, based on the moisture content of the wall base 2, the quality of the adhesion state of the exterior material 3 is determined (first determination step S3). In the present embodiment, first, the moisture content input to the moisture content storage unit 18A and the first determination unit 19A of the program unit 19 are read into the working memory 17. Then, by being executed by the arithmetic unit 15, the first determination unit 19A can function as a means for determining the quality of the adhesion state of the exterior material 3 for the computer 10A.

[0053] The determination of the quality of the adhesion state of the exterior material 3 can be appropriately carried out as long as it is based on the moisture content of the wall base 2. In the first determination step S3 of the present embodiment, when the moisture content is greater than a predetermined threshold value, it is determined that the adhesion state is poor.

[0054] The threshold value is preferably specified in advance, for example, before the diagnostic method is implemented. The threshold value of the present embodiment is input to the threshold value storage unit 18C.

[0055] The threshold value can be set as appropriate as long as it can determine the quality of the adhesion state. As described above, according to the findings of the inventors, there is a certain correlation between the moisture content of the wall base 2 and the poor adhesion of the exterior material 3 due to freezing damage. Therefore, in the present embodiment, the threshold value is set based on the relationship between the moisture content (%) of the wall base 2 and the cohesive strength (N / mm 2 ) of the exterior material 3.

[0056] FIG. 5 is a graph showing the relationship between the moisture content of the wall base 2 and the cohesive strength of the exterior material 3. In FIG. 5, for a plurality of wall bases 2 composed of the same type of material, the measurement results of the moisture content of the wall base 2 and the cohesive strength of the exterior material 3 are plotted respectively. For the measurement of the moisture content, for example, an electric resistance type moisture meter (the moisture content measurement unit 11 shown in FIG. 1) is used. For the measurement of the cohesive strength (tensile adhesion strength), a known Kenken type adhesion tester (not shown) is used. FIG. 5 shows a regression line 25 indicating the correlation between the moisture content and the cohesive strength.

[0057] As shown in FIG. 5, there is a correlation between the moisture content of the wall base 2 and the cohesive strength of the exterior material 3. As the moisture content increases, the cohesive strength decreases, and the adhesion strength of the exterior material 3 deteriorates.

[0058] The threshold value T1 of the present embodiment is specified based on the regression line 25 and the cohesive strength required for the exterior material 3. The required cohesive strength can be set as appropriate based on a predetermined standard or the like. In the present embodiment, based on Q-CAT (Combined Quality Approval Standard for Exterior Tiles and Organic Adhesives), the moisture content when the cohesive strength of the regression line 25 is 0.3 N / mm 2 is specified as the threshold value T1.

[0059] The relationship between the moisture content of the wall base 2 and the cohesive strength of the exterior material 3 tends to vary depending on the type of material of the wall base 2. For this reason, in the present embodiment, prior to the implementation of the diagnosis method, it is desirable to specify the threshold value T1 for each of the plurality of types of materials used for the wall base 2, and for those threshold values T1 to be input into the threshold value storage unit 18C. Thereby, in the first determination step S3, according to the type of material of the wall base 2, since the threshold value T1 is determined in advance, it is possible to accurately and quickly determine whether the adhesion state of the exterior material 3 is good or bad.

[0060] In the first determination step S3, when the moisture content of the wall base 2 is less than or equal to the predetermined threshold value T1, it is determined that the adhesive strength of the exterior material 3 is good ( "good" in the first determination step S3). In this case, it is judged that there is no poor adhesion of the exterior material 3 due to frost damage on the outer wall 1 to be diagnosed, and a series of processes of the diagnosis method are completed.

[0061] On the other hand, in the first determination step S3, when the moisture content of the wall base 2 is greater than the predetermined threshold value T1, it is determined that the adhesive strength of the exterior material 3 is poor (there is poor adhesion of the exterior material 3 due to frost damage) ( "poor" in the first determination step S3). In this case, the step S4 of performing a destructive inspection on the exterior material 3 is carried out.

[0062] As described above, in the present embodiment, the moisture content is measured for each of the plurality of wall panels 2P. For this reason, in the first determination step S3, it is desirable to determine whether the adhesion state is good or bad for each of the plurality of wall panels 2P. Thereby, it becomes possible to efficiently determine the adhesive strength of the exterior material 3 over the entire wall base 2.

[0063] The determination result of the adhesion state of the exterior material is stored in the determination result storage unit 18B shown in FIG. 3. In the diagnosis method of the present embodiment, when the display unit 19B of the program unit 19 is executed by the arithmetic unit 15, the determination result of the adhesion state is displayed on the output unit 13. FIG. 6 is a diagram showing the determination result of the adhesion state of the exterior material 3 of the present embodiment. In FIG. 6, the determination result of the adhesion state of the exterior material 3 is displayed for each of the plurality of wall panels 2P (shown in FIG. 1).

[0064] [Destructive inspection] Next, in the diagnostic method of the present embodiment, a destructive inspection is performed on the exterior material 3 (shown in FIGS. 1 and 2) determined to have a poor adhesion state (step S4). In the destructive inspection of the present embodiment, first, at least a part of the exterior material 3 (a plurality of tiles 7) is peeled off from the wall base 2. Then, the adhesion failure due to freezing damage is confirmed by visual inspection or the like by the inspector. Thereby, in the diagnostic method of the present embodiment, the adhesion state of the exterior material 3 can be surely diagnosed.

[0065] In the first determination step S3 of the present embodiment, the quality of the adhesion state is determined for each of the plurality of wall panels 2P (shown in FIG. 1). Therefore, in step S4 of the present embodiment, a destructive inspection is performed on the wall panel 2P determined not to have a good adhesion state among the plurality of wall panels 2P. Thereby, in the diagnostic method of the present embodiment, while suppressing damage to the outer wall 1 caused by the destructive inspection, the adhesion failure due to freezing damage can be surely diagnosed.

[0066] In the present embodiment, after the step S4 of performing the destructive inspection, in the method for repairing the outer wall 1 described later, the exterior material 3 is repaired (step S5).

[0067] [Operation of the method for diagnosing the outer wall (diagnostic device for the outer wall)] The diagnostic method (diagnostic device 10) of the present embodiment can determine the adhesion failure of the exterior material 3 due to freezing damage, which is difficult to determine by the impact sound inspection, based on the measurement result of the moisture content of the wall base 2. Therefore, in the diagnostic method of the present embodiment, the adhesion state of the exterior material 3 can be diagnosed with high accuracy.

[0068] In the present embodiment, since the quality of the adhesion state of the exterior material 3 is determined based on the moisture content of the wall base 2 and a predetermined threshold value, the skill of the inspector is not required. Therefore, in the diagnostic method of the present embodiment, the adhesion state of the exterior material 3 can be stably diagnosed.

[0069] In the diagnostic method of the present embodiment, prior to the water content measurement step S2, a second determination step S1 for diagnosing the quality of the adhesion state based on the tapping inspection is performed, so that it is also possible to determine the poor adhesion of the exterior material 3 due to the peeling of the exterior material 3 and the adhesive 6. Therefore, in the diagnostic method of the present embodiment, the adhesion state of the exterior material 3 can be diagnosed with higher accuracy.

[0070] [Method for repairing exterior wall] Next, the method for repairing the exterior wall 1 of the present embodiment (hereinafter, may be simply referred to as "repair method") will be described. The repair method of the present embodiment includes a step S5 of repairing the exterior material 3 determined to have a poor adhesion state in the above-described diagnostic method.

[0071] [Repair of exterior material] In the step S5 of the present embodiment, similar to the conventional method for repairing the exterior material 3, for example, replacement of the exterior material 3 with a poor adhesion state or injection of an epoxy resin or the like is performed. Thereby, the exterior material 3 can be brought into a good adhesion state. Further, in the step S5, when the exterior material 3 that was in a good adhesion state despite being broken by the destructive inspection is included, the exterior material 3 is fixed to the wall base 2 again.

[0072] In the repair method of the present embodiment, since the exterior material 3 is repaired based on the highly accurate diagnostic result in the above-described diagnostic method, it is possible to surely maintain the state in which the exterior material 3 is fixed to the wall base 2.

[0073] In the step S5, it is desirable to identify the factor (such as a through hole such as a screw fixed to the exterior wall 1) that allowed water to penetrate into the wall base 2 and perform repair (such as waterproof treatment). Thereby, in this embodiment, it is possible to surely prevent the poor adhesion of the exterior material 3 due to freezing damage.

[0074] [Diagnostic method for exterior wall (Second embodiment)] As shown in FIG. 4, in the previous embodiments, prior to the moisture content measurement step S2, the second determination step S1 for diagnosing the quality of the adhesion state based on the hitting sound generated by hitting the outer surface 3o of the exterior material 3 was performed, but it is not limited to such a mode. For example, when it is not necessary to perform the hitting sound inspection (for example, when the hitting sound inspection has been performed in advance, etc.), the second determination step S1 may be omitted and the process may be carried out from the moisture content measurement step S2.

[0075] As described above, the particularly preferred embodiments of the present invention have been described in detail, but the present invention is not limited to the illustrated embodiments and can be implemented in various forms.
