The first inclined surface 15b is inclined and extends so as to form a predetermined angle θ1 (45 ° in this example) with respect to the surface 11a. In this example, the surface 11a, the first bottom surface 15a, the first inclined surface 15b, and the first side surface 15c of the first wall panel 11 are composed of flat surfaces, but the surface is not limited to the curved surface. Or a surface having irregularities. Further, the first bottom surface 15a does not have to be parallel to the surface 11a of the first wall panel 11.

The second wall panel 12 is provided with a second bottom surface that extends substantially parallel to the surface 12a of the second wall panel 12 and is recessed from the surface 12a of the second wall panel 12 by a predetermined distance. You may. In that case, the second bottom surface constitutes at least a part of the second bottom surface portion 14b of the inside corner groove 14. For example, the second bottom surface may be located on the same plane as the first side surface 15c of the first wall panel 11 and may be a surface connected to the second inclined surface 16b.

The second inclined surface 16b is inclined and extends so as to form a predetermined angle θ2 (45 ° in this example) with respect to the surface 12a. Further, the second inclined surface 16b of this example extends in parallel with the first inclined surface 15b, but is not limited to this. The distance between the first inclined surface 15b and the second inclined surface 16b can be, for example, 40 mm, but is not limited thereto. In terms of the appearance of the design, the interval is preferably smaller, and from the viewpoint of workability of the sealing 17 and the like, the interval is preferably large. The distance between the first inclined surface 15b and the second inclined surface 16b is preferably 30 mm to 50 mm in order to achieve both the effects of the design and the workability. In this example, the surface 12a and the second inclined surface 16b of the second wall panel 12 are composed of a flat surface, but the present invention is not limited to this, and may be a curved surface or a surface having irregularities. good.

As described above, in the corner wall structure 10 of the present embodiment, the corner groove 14 is formed in the first recess 15 formed on the surface 11a of the first wall panel 11 and the second wall panel 12. It is composed of a second recess 16 formed on the surface 12a. That is, the inside corner groove 14 is formed so as to be concave from the surface 11a of the first wall panel 11 and also concave from the surface 12a of the second wall panel 12. With such a configuration, it is possible to cope with the inside corners 2 having different heights of the walls on both sides (first wall panel 11 and second wall panel 12), and it is possible to realize a highly designed appearance. .. That is, for example, when the inside corner is formed by the inside corner wall panel having an L-shaped cross section and the flat wall panels on both the left and right sides as in the conventional case, when the heights of the wall panels on both the left and right sides are different. The corner wall panel having an L-shaped cross section had to be cut and used, but in the present embodiment, the end surface 12b of the second wall panel 12 is abutted against the surface 11a of the first wall panel 11. Therefore, even if the heights of the left and right wall panels (first wall panel 11 and second wall panel 12) are different, the inside corner portion 2 can be easily formed. Further, the inside corner groove 14 is composed of a first recess 15 formed on the surface 11a of the first wall panel 11 and a second recess 16 formed on the surface 12a of the second wall panel 12. , The inside corner groove 14 can be easily seen from various angles, and the appearance of a wall having a high three-dimensional design can be realized.

More specifically, the inside corner groove 14 of this example can be visually recognized from a direction parallel to the first wall panel 11 (see arrow A in FIG. 5) (see FIG. 2B), and the second wall panel. It is configured to be visible from a direction parallel to 12 (see arrow B in FIG. 5) (see FIG. 2A). With such a configuration, the inside corner groove 14 can be easily seen from various angles, and the appearance of the outer wall having a high three-dimensional design can be realized.

Further, as shown in FIG. 5, the bottom portion 14c formed at the boundary between the first bottom surface portion 14a and the second bottom surface portion 14b of the inner corner groove 14 is a V-shaped corner portion in a sectional view in a plan view (this example). By forming the vertical corners), it is possible to realize a corner portion 2 having a sharp appearance with an edge (clear outline). Further, since the bottom portion 14c of the inner corner groove 14 is composed of the first bottom surface 15a and the first side surface 15c of the first wall panel 11, the positions of the first wall panel 11 and the second wall panel 12 are aligned. The bottom portion 14c of the inside corner groove 14 has the intended shape regardless of the deviation or the like. That is, in the case of this example, since the bottom portion 14c of the inner corner groove 14 is surely formed in a straight line, an appearance with high design can be realized.

The depth of the first bottom surface portion 14a (distance in the panel thickness direction from the surface 11a (exposed portion 11d) to the first bottom surface portion 15a) is the depth of other grooves such as decorative joints formed on the first wall panel 11. It is preferable that it is equivalent to. With such a configuration, it becomes difficult for a step to be formed on the bottom surface at the portion where the other groove portion and the first recess 15 intersect, and the workability in the filling work of the wet sealing material is improved. In addition, it is possible to suppress a decrease in design due to a step on the outer wall surface. The other groove may be, for example, a horizontal groove 18a (decorative joint) extending in the horizontal direction, a vertical groove 19a formed at a boundary with another adjacent wall panel 22 (see FIG. 4), or the like. can. The other groove may be a groove formed at a boundary with another wall panel adjacent in the vertical direction.

Similarly, the depth of the second bottom surface portion 14b (distance in the panel thickness direction from the surface 12a to the surface 17a of the first side surface 15c and the sealing 17) is the other groove portion (this) formed in the second wall panel 12. In the example, it is preferable that the depth is equivalent to the groove depth of the horizontal groove 18b extending in the horizontal direction and the vertical groove 19b) extending in the vertical direction.

The vertical groove 19a provided in the first wall panel 11 and the wall panel 22 adjacent to the first wall panel 11 has an isosceles trapezoidal cross section having a bottom surface and an inclined surface. With such a configuration, the shape of the inner corner groove 14 and the shape of the vertical groove 19a are unified, and the design of the appearance is improved. The isosceles trapezoidal shape including a cross section includes a case where the cross section is rectangular. Similarly, the cross-sectional shape of the lateral groove 18a is preferably an isosceles trapezoidal shape. From the same viewpoint, the vertical groove 19b provided at the boundary between the second wall panel 12 and the wall panel 21 adjacent to the second wall panel 12 and the horizontal groove 18b provided on the second wall panel 12 are also provided. , It is preferable to have an isosceles trapezoidal shape such as a cross section. The vertical grooves 19a and 19b are provided at the joints between adjacent wall panels (first wall panel 11 and wall panel 22, second wall panel 12 and wall panel 21), but the wall panels are used as decorative joints. It may be formed in the middle part of.

The inclination angle θ1 of the first inclined surface 15b with respect to the exposed portion 11d of the surface 11a is preferably 45 ° or more and 60 ° or less. With such a configuration, work such as filling of the sealing material (forming the sealing 17) inside the inside corner groove 14 and spray coating becomes easy. In addition, the visibility of the contour of the inner corner groove 14 is improved, and the design can be enhanced. From the same viewpoint, the inclination angle θ2 of the second inclined surface 16b with respect to the surface 12a is preferably 45 ° or more and 60 ° or less. The inclination angle θ1 of the first inclined surface 15b and the inclination angle θ2 of the second inclined surface 16b are not limited to the above range, and may be, for example, 90 °.

Further, in the inside of the inner corner groove 14, a sealing 17 is provided at the boundary portion between the first wall panel 11 and the second wall panel 12. By providing the sealing 17 inside the inner corner groove 14, it becomes difficult to see from the outside, and the design of the appearance can be enhanced. The sealing 17 is a wet sealing material filled in a notch (sealing pocket) 15d formed in the first wall panel 11 and a notch (sealing pocket) 16c formed in the second wall panel 12. It is configured. The notch portion 15d is a chamfered notch portion that opens to the first side surface 15c and the facing portion 11c, and the notch portion 16c opens to the second inclined surface 16b and the end surface 12b of the second wall panel 12. There is. Further, the sealing 17 is formed so that the exposed surface 17a is flush with the first side surface 15c, and constitutes a part of the second bottom surface portion 14b of the inside corner groove 14. In this example, the sealing pocket is composed of the notch portion 15d on the first wall panel 11 side and the notch portion 16c on the second wall panel 12 side, but it may be composed of only one of them. .. Further, the shape of the sealing pocket is not particularly limited as long as it is formed at the boundary portion between the first wall panel 11 and the second wall panel 12.

With such a configuration, a special spatula or the like becomes unnecessary, and the wet sealing material can be pressed by using the first side surface 15c of the first wall panel 11 as a guide with a normal flat plate-shaped spatula, so that the construction work of the sealing 17 can be performed. Becomes easier. Further, the sealing 17 makes it possible to make the step caused by the manufacturing error, the construction error, etc. that may occur between the first wall panel 11 and the second wall panel 12 inconspicuous.

As shown in FIG. 5 of this example, the position of the sealing 17 is separated from the bottom portion 14c (corner portion) formed at the boundary between the first bottom surface portion 14a and the second bottom surface portion 14b of the inside corner groove 14. The position is preferred. By setting the position away from the corner portion of the inner corner groove 14 in this way, it is possible to facilitate the sealing work at the site. From the viewpoint of enhancing workability in this way, it is more desirable that the position of the sealing 17 is outside the surface 11a of the first wall panel 11. That is, for example, by providing the notch portion (sealing pocket) 15d not on the first wall panel 11 side but on the second wall panel 12 side and filling it with a wet sealing material, the sealing work becomes easier. ..

It is preferable that the inside corner groove 14 has a symmetrical shape as in this example. That is, it is symmetrical with respect to the virtual plane S (see FIG. 5) that bisects the angle formed by the surface 11a of the first wall panel 11 and the surface 12a of the second wall panel 12 at the inside corner portion 2. Is preferable. In this example, the virtual plane S passes through the bottom portion 14c (the boundary portion between the first bottom surface 15a and the first side surface 15c) of the inside corner groove 14, and the surface 11a of the first wall panel 11 and the second wall panel 12 It is a plane forming 45 ° with respect to the surface 12a. With such a configuration, for example, even if the relationship between the first wall panel 11 and the second wall panel 12 constituting the inside corner portion 2 is reversed, the same appearance can be obtained. Therefore, the method of arranging the first wall panel 11 and the second wall panel 12 constituting the inside corner portion 2 is less restricted. Even when the relationship between the wall panels 12 has to be reversed, an unnatural step or the like does not occur, and it is possible to maintain a high degree of design.

Further, the facing portion 11c is preferably located on the outermost surface 11a of the first wall panel 11 in the thickness direction. According to this, the facing portion 11c is located on the same plane as the exposed portion 11d or outside the exposed portion 11d in the thickness direction. As a result, for example, the wall panel 21 shown in FIG. 4 (the wall panel adjacent to the second wall panel 12 on the opposite side of the first wall panel 11) and the first wall panel 11 are installed first. Even in this case, the second wall panel 12 can be easily installed so as to be fitted between the wall panel 21 and the first wall panel 11. That is, for example, when the facing portion 11c is retracted from the exposed portion 11d (located inside the exposed portion 11d of the first wall panel 11 in the thickness direction), the first wall panel 11 installed in advance is used. When the end surface 12b of the second wall panel 12 is brought into contact with the facing portion 11c, the second wall panel 12 must be slid toward the facing portion 11c. Further, when the wall panel 21 of the second wall panel 12 adjacent to the side opposite to the first wall panel 11 is installed first, the second wall panel 11 is located between the first wall panel 11 and the wall panel 21. It becomes difficult to install the wall panel 12. On the other hand, according to the present embodiment, even if the first wall panel 11 and the wall panel 21 located on both sides of the second wall panel 12 are installed first, the second wall panel 12 can be easily attached. Can be done.

More preferably, as in this example, it is desirable that the facing portion 11c is located on the same plane as the exposed portion 11d. According to this, the end surface 12b of the second wall panel 12 can be arranged on the facing portion 11c of the first wall panel 11 while moving along the exposed portion 11d of the first wall panel 11 installed in advance. That is, it is not necessary to slide the second wall panel 12 toward the facing portion 11c of the first wall panel 11 in order to bring the end surface 2b of the second wall panel 12 into contact with the facing portion 11c of the first wall panel 11. , The installation work of the second wall panel 12 becomes easier.

Further, it is preferable that the vertical length of the inner corner groove 14 is substantially the same as the vertical length (height) of the second wall panel 12. In this case, a first recess 15 having the same length as the vertical length of the second wall panel 12 is provided in the first wall panel 11, and the second wall panel 12 is abutted against the first wall panel 11. The inside corner groove 14 is formed only in the abutted inside corner portion 2. According to this, even if the lengths of the first wall panel 11 and the second wall panel 12 in the vertical direction are different, the inside corner portion 2 can be formed without cutting the length of the first wall panel 11. , It is possible to suppress the increase in cost.

Here, FIGS. 6 and 7 show a modified example of the inside corner wall structure 10. In the corner wall structure 30 shown in FIG. 6, a second wall panel 32 having a length smaller in the vertical direction than the first wall panel 31 is arranged above the first wall panel 31. The inner corner groove 34 is composed of a first recess 35 of the first wall panel 31 and a second recess 36 of the second wall panel 32. Further, the entrance groove 34 is provided in a vertical range corresponding to the second wall panel 32, that is, from the lower end portion 32a to the upper end portion 32b of the second wall panel 32. Further, at the height of the lower end portion 32a of the second wall panel 32, a horizontal groove 38a is formed in the first wall panel 31, and is continuously provided at the lower end portion of the inner corner groove 34. It is preferable that the groove depth of the horizontal groove 38a and the cross-sectional shape perpendicular to the extending direction are the same as those of the first recess 35 constituting the inside corner groove 34. With such a configuration, it becomes difficult for a step to be formed on the bottom surface at the portion where the other groove portion (horizontal groove 38a) and the first recess 35 intersect, and it is possible to suppress the deterioration of the design and to give a sense of unity to the shape. Therefore, the design of the appearance is improved. The position of the second wall panel 32 having a short length is not limited to the upper part of the first wall panel 31 as shown in FIG. 6, but may be the middle stage or the lower part of the first wall panel 31.

In the example shown in FIG. 7, the second wall panel 42, which has a smaller vertical length than the first wall panel 41, is arranged below the first wall panel 41. Also in this case, the inside corner groove 44 is composed of the first recess 45 of the first wall panel 41 and the second recess 46 of the second wall panel 42. Further, it is preferable that the inside corner groove 44 is provided in a vertical range corresponding to the second wall panel 42, that is, from the lower end portion 42a to the upper end portion 42b of the second wall panel 42. Further, at the height of the upper end portion 42b of the second wall panel 42, a horizontal groove 48a is formed in the first wall panel 41 and is continuously provided in the upper end portion 42b of the inner corner groove 44. It is preferable that the groove depth of the horizontal groove 48a and the cross-sectional shape perpendicular to the extending direction are the same as those of the first recess 45 constituting the inside corner groove 44. With such a configuration, it becomes difficult for a step to be formed on the bottom surface at the portion where the other groove portion (horizontal groove 48a) and the first recess 45 intersect, and it is possible to suppress the deterioration of the design and to give a sense of unity to the shape. Therefore, the design of the appearance is improved. The position of the second wall panel 42 having a short length is not limited to the lower part of the first wall panel 41 as shown in FIG. 7, but may be the middle stage or the upper part of the first wall panel 41.

The inside corner wall structure according to the present invention is not limited to the configuration of the above-described embodiment, and can be realized by various configurations without departing from the contents described in the claims. .. For example, the first bottom surface portion 14a (first bottom surface 15a) and the second bottom surface portion 14b (first side surface 15c and the surface 17a of the sealing 17) of the inside corner groove 14 are not essential configurations. Further, the building 1 may be provided with a plurality of inside corners 2 having different shapes. In that case, the positions of the plurality of corner portions 2 can be provided at different positions on the same layer or on different layers.
