Description

The present invention relates to a tile wall diagnostic system and a tile wall diagnostic method capable of determining the degree of deterioration of a tile wall based on an image of a tile wall joint.

On the outer wall of the building where the tiles are glued, the tiles are pasted by applying a base adhesive to the tiles and providing joints at regular intervals on the base. Therefore, the base adhesive located at the joint between adjacent tiles is not covered by the tiles, and the part exposed to the outside deteriorates and rainwater etc. infiltrates, and the base exterior material etc. to which the tiles are attached May cause deterioration.

Since the base adhesive generally contains a thermosetting resin, photooxidation decomposition is likely to occur due to exposure to ultraviolet rays due to long-term solar radiation. Further, in the case of a silylated epoxy resin-based base adhesive, a post-curing reaction occurs due to rainwater or heat. As described above, when deterioration progresses due to the influence of ultraviolet rays, heat, rainwater, etc., cracks occur, and as a result, the protective property of the base material of the adhesive is lowered, which causes deterioration of the base material and the like.

A method for diagnosing such a secular change of a tile wall is described in, for example, Patent Document 1. This conventional technique is a wall surface diagnosis result recording system that records a diagnosis result for a diagnosis target portion on a wall surface, is a wall surface image taken by an imaging means, and records diagnosis result information indicating a diagnosis result by a diagnosis worker. A wall image acquisition means for acquiring at least a wall surface image including at least the diagnostic target portion, and a wall surface image analysis means for analyzing the diagnosis result information of the wall surface image acquired by the wall surface image acquisition means and specifying the diagnosis result indicated by the diagnosis result information. A wall surface diagnosis result recording including The system has been proposed.

It is a flowchart for demonstrating the diagnostic procedure of embodiment of this invention which concerns on the tile wall diagnostic method.

Hereinafter, the tile wall diagnostic system 1 according to the embodiment of the present disclosure will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a part of the tile wall 10 photographed by the imaging unit 2 of the tile wall diagnostic system 1 of the embodiment of the present invention, and FIG. 2 shows a case where the tile wall 10 has a broken joint structure. It is a front view showing an example, and FIG. 3 is an enlarged front view of a part of the tile wall 10 shown in FIG. FIG. 4 is a front view showing an example in which the tile wall 10 has a through joint structure, and FIG. 5 is a front view showing a part of the tile wall 10 near the ground of the tile wall 10 shown in FIG.

The tile wall 10 targeted by the tile wall diagnostic system 1 of the present embodiment typically has a tear joint structure shown in FIGS. 2 and 3 and a through joint structure shown in FIGS. 4 and 5. .. In the tile wall 10 having a tear joint structure, the tiles 11 are positioned so that the rows in the vertical direction (vertical direction in FIG. 2) are alternately displaced by 1/2 of the arrangement interval of the tiles 11, and the base adhesive 13 is applied to the tile wall 10 of the building. It is adhered to the base 12, and a joint 14 bent in a zigzag shape is formed between the tiles 11, and the base adhesive 13 is exposed.

Since such joints 14 are retracted from the surface of each tile 11, when it rains, rainwater flows down in the direction of arrow m1 along the joints 14 extending up and down, and extends horizontally along the lower end thereof. When it flows into the joint 14, it falls on the upper surface of the tile 11 located below the joint 14. The rainwater that has fallen on the upper surface of the tile 11 flows to both sides along the upper surface of the lower tile 11 as indicated by the arrow m2, and flows down to the joint 14 between the lower tiles 11 as indicated by the arrow m3.

As described above, in the tile wall 10 having a broken joint structure, since the joint 14 extending vertically and the joint 14 extending horizontally intersect at the joint intersection 14a, rainwater tends to stay at each joint intersection 14a. The degree of deterioration of the base adhesive 13 located at each joint intersection 14a is higher than that of other parts. Therefore, when the tile wall 10 has a broken joint structure, it is photographed by the photographing unit 2 so as to include each joint intersection 14a, and is photographed as a sampled image.

Further, in the tile wall 10 having a joint structure shown in FIGS. 4 and 5, the tiles 11 are arranged in the vertical direction and the horizontal direction, and are adhered to the base 12 of the building by the base adhesive 13, and each tile 11 is attached. A grid-like joint 14 is formed between them, and the base adhesive 13 is exposed.

Since the joint 14 is retracted from the surface of each tile 11, when it rains, rainwater flows down in the direction of the arrow m3 along the joint 14 extending up and down, and at the arrow m4 along the horizontal joint 14. Move as shown and join the rainwater flowing down in the direction of the arrow m3. Further, since the rainwater adhering to the upper part of the wall surface 10 flows down in the direction of the arrow m3 along the joint 14 extending vertically, the joint 14 extending vertically at the lower part of the wall surface 10 receives more rainwater than the upper part. It will pass through, and the deterioration of the base adhesive 13 will be promoted more than in the upper region.

As described above, in the joint wall 10 having a through joint structure, at the joint intersection 14a between the joint 14 extending vertically and the joint 14 extending horizontally, the rainwater flowing along the joint 14 extending vertically and the joint 14 extending horizontally are formed. Since the rainwater moving along the joints merges, the photographing unit 2 takes a picture so that each joint intersection 14a is included, and is taken as a sampled image. Further, it is preferable that each joint intersection 14a uses an image taken so as to include a portion located at the lower part of the wall surface 10, for example, each joint intersection 14a located at the bottom, as a sampling image.

Since the tile wall 10 has a plurality of tiles 11 and a base adhesive 13 for adhering the plurality of tiles 11 to the base 12, in the first step S1, the plurality of tiles 11 and the joints 14 of the tile wall 10 are formed. Although the photographing target portion 15 including the above is photographed by the photographing unit 2, only the surface of the base adhesive 13 exposed from the joint 14 may be taken out by editing the image.

A plurality of shooting target portions 15 are selected from one tile wall 10. The position and range of the photographing target portion 15 are determined by an appropriate method. The image target portion 15 is preferably the surface of the base adhesive 13 exposed from the joints 14 between the tiles 11, and the vertical joints 14 extending vertically and the horizontal joints 14 extending horizontally intersect with each other. A joint intersection is preferable, but the present invention is not limited to this.

Next, the third step S3 is carried out in which the deterioration determination unit 4 determines the degree of deterioration of the imaging target unit 15 based on the first image information read from the photographing unit 2 in the second step S2.

In the present embodiment, deterioration determining unit 4 compares the storage portion 4a second image information representing a feature of the reference image of the tile wall 10 is stored, a first image information, and a second image information, It includes a reference image extraction unit 4b that extracts the reference image having the highest degree of similarity from the second image information.

In addition, the second image information includes information on the number of years elapsed since the construction of the tile wall 10 of the reference image. As a result, in the third step S3, the deterioration determination unit 4 deteriorates due to the number of years elapsed from the construction of the tile wall 10 of the photographing target unit 15 from the second image information of the reference image extracted by the reference image extraction unit 4b. The progress can be estimated and the degree of deterioration of the imaging target portion 15 can be determined.

Finally, in the third step S3, the fourth step S4 is carried out in which the output unit 5 displays an image of information indicating the degree of deterioration determined by the deterioration determination unit 4.

According to the above embodiment, the following effects are obtained.
(1) Deterioration diagnosis is performed without the need for a diagnosis by a diagnostic worker because the photographing unit 2 photographs the image target unit 15 and determines the deterioration based on the first image information representing the characteristics of the photographed image. It is possible to shorten the time required for repair, suppress variations in diagnostic results, and accurately grasp the need for repair.

(2) High-sensitivity deterioration diagnosis because deterioration is determined based on the first image information that is exposed from the joint 14 and represents the characteristics of the image on the surface of the base adhesive 13 that is easily affected by ultraviolet rays, heat, rainwater, and the like. Is possible.

(3) The first image information is compared with the second image information representing the characteristics of the reference image of the tile wall 10 recorded in advance, and the reference image having the highest degree of similarity is extracted from the second image information and extracted. Since the degree of deterioration of the imaging target portion 15 is determined based on the obtained reference image, an objective and accurate deterioration diagnosis can be performed.

In each of the above-described embodiments, the case where the captured image and the reference image are two-dimensional images has been described, but in other embodiments of the present invention, the captured image and the reference image are three-dimensional, which is also called a so-called 3D image or a stereoscopic image. Images may be used. As a result, cracks and ridges on the surface exposed from the joint 14 of the base adhesive 13 can be detected more accurately, and the degree of deterioration of the tile wall 10 can be determined with high accuracy.

In still another embodiment of the present invention, the progress rate of deterioration can be determined by accumulating the captured images of the joints between the tiles at a fixed position taken by the photographing unit in chronological order. If it is stored as a database in the storage unit, the degree of future deterioration can be estimated based on the current captured image. Thereby, it is possible to propose to the owner when, the period or the deadline for repairing the tile wall 10. Furthermore, considering the statistical probability of the occurrence of earthquakes and typhoons, it is possible to propose a safer repair time, period or deadline.

In each of the above-described embodiments, the case where the photographed image of the tile wall 10 deteriorated by the adhesion of water is used as the reference image has been described, but in still another embodiment of the present invention, the tile wall 10 deteriorated by sunlight is used. The captured image may also be added to the reference image for use. As a result, the degree of deterioration of the tile wall 10 can be determined by considering not only the deterioration due to the adhesion of water but also the influence of the deterioration due to the ultraviolet rays of solar radiation, and the factors of deterioration can be expanded. , The judgment accuracy can be made higher.

In the above, the deterioration diagnosis system and the deterioration diagnosis method of the tile wall have been described, but the present invention is applicable not only to the tile wall but also to the deterioration diagnosis of other outer walls and inner walls.
