  However, in the fitting mode as described above, when the width dimension of the outer wall joint is not constant on the outer wall surface due to construction error or the like, for example, there are a plurality of outer wall vertical joints having different outer wall width dimensions. Even if the gaskets are fitted so that the depth positions of both end edges of the outermost fins are the same, the outermost side facing the outdoor side is not suitable for the outer wall joint with a small width dimension. The depth position of the intermediate part in the width direction of the fin becomes deep, and in the outer wall joint portion where the width dimension is large, the depth position of the intermediate part of the width dimension of the outermost fin facing the outdoor side becomes shallow, and There is a problem that the joint bottom is recessed due to the bending, and therefore, the effect of light and shadow causes a conspicuous joint and a non-conspicuous joint, thereby impairing the design of the outer wall surface.

  In view of the above problems, an object of the present invention is to provide an outer wall joint structure that does not impair the design of the outer wall surface with a gasket even if the width dimension of the outer wall joint is not constant.

The above-mentioned problem is that the same gasket for water stop is placed on the outer wall joint of the outer wall surface of the outer wall surface where the width dimension of the outer wall joint is not constant, and the insertion depth position of the intermediate portion in the width direction of the outermost fin facing the outdoor side is determined. , Are fitted so as to be at the same depth position between mutually parallel facing surface parts sandwiching the joint space part,
In the gasket, the outermost fin has an R shape that protrudes outward from the center to both end edges, and both end edges of the outermost fin are bent, and in the fitted state, the outer wall In relation to the width dimension of the joint, in the part where the both end edge portions of the outermost fin protrude to the outdoor side from the mutually parallel opposing surface portions sandwiching the space portion in the joint, the both end edge portions of the outermost fin are It is solved by the structure of the outer wall joint characterized in that it is adapted to be along the outer wall surface by the action of bending.

  In this structure, the same gasket for water stop is placed on the outer wall joint of the outer wall surface where the width dimension of the outer wall joint is not constant, and the insertion depth position of the intermediate portion in the width direction of the outermost fin facing the outdoor side is Since it is fitted so as to have the same depth position between mutually parallel facing surface parts sandwiching the underground space part, the conspicuousness of the joint due to the difference in the depth position of the intermediate part in the width direction of the outermost fin facing the outdoor side There is no difference in condition, and therefore the design of the outer wall surface is not impaired by the gasket even if the width dimension of the outer wall joint is not constant.

  In addition, in the gasket, the outermost fin has an R shape that is convex outward from the center to both end edges, and both the end edges of the outermost fin are bent, and the fitting state In relation to the width dimension of the outer joint, the both end edges of the outermost fins protrude from the opposing surface parts parallel to each other across the joint inner space part to the outdoor side. However, the joint bottom does not dent and the projecting portion does not impair the design of the outer wall surface.

  In addition, the phrase “outer wall surface where the width dimension of the outer wall joint is not constant” means that there are multiple outer wall vertical joints having different width dimensions in parallel or in series, In addition to the outer wall surface in which multiple outer wall horizontal joints of different widths exist in parallel or in series, the outer wall surface of the outer wall vertical joint and the outer wall horizontal joint of different width dimensions, etc. In one outer wall joint, the width dimension is used in the meaning including the outer wall surface where the outer wall joint exists such that the width dimension gradually changes from one end side to the other end side or gradually decreases.

  Since the present invention is as described above, the design of the outer wall surface is not impaired by the gasket even if the width dimension of the outer wall joint is not constant.

FIGS. 1A to 1C are cross-sectional views showing joints having different width dimensions existing on the outer wall surface and a state in which a gasket is fitted into the joints. Fig. (A) is a sectional view of the gasket in a natural state before fitting, and Fig. (B) is a partially enlarged sectional view showing the outermost fin facing the outdoor side in an enlarged manner. Drawing (a)-figure (C) are sectional views which show each joint which differs in the width dimension which exists in an outer wall surface, and a gasket inserted in each joint in a separated state, respectively. It is a figure which shows the gasket of other embodiment of this invention, Comprising: (a) is sectional drawing of the gasket in the natural state before fitting, (b) is an enlarged outermost fin facing the outdoor side. FIG.

  Next, embodiments of the present invention will be described with reference to the drawings.

  In the embodiment shown in FIG. 1 to FIG. 3, 1 and 1 are outer wall materials made of ceramics and the like, 2... Are outer wall joints between them, 3 is a gasket, As shown in FIGS. 1 (a) to (c) and FIGS. 3 (a) to (c), a plurality of outer wall vertical joints 2 with different width dimensions exist in parallel. Specifically, the width dimension a of the outer wall joint 2 shown in FIGS. 1 (a) and 3 (a) is, for example, 8 mm, and the width dimension of the outer wall joint 2 shown in FIGS. 1 (b) and 3 (b). b is, for example, 10 mm, and the width dimension c of the outer wall joint 2 shown in FIGS. 1C and 3C is, for example, 12 mm.

  As shown in FIGS. 2 (a) and 2 (b), the gasket 3 includes an outermost fin 4 facing the outdoor side, an innermost fin 5 on the indoor side, and an intermediate fin 6 therebetween. The core material 7 is embedded in a rubber-like elastic material. In addition, in the gasket 3 of this embodiment, it has the structure which used the elastic material of a different color by the part 8 which faces the outdoor side, and the main-body part 9, and combined them, and it suits it in relation to an outer wall surface. Manufacture of colored gaskets can be handled by changing only the elastic material of the portion 8 facing the outdoor side.

  In this gasket 3, the width dimension of the outermost fin 4 facing the outdoor side is designed to be larger than the assumed maximum joint width dimension, and the fin 4 is the outermost from the center portion to both end edges. It has an outwardly convex R shape, and both end edges 4a, 4a of the fin 4 are bent.

  1 and 3, the same gasket 3 has a depth at the intermediate portion in the width direction of the outermost fin 4 facing the outdoor side on each of the plurality of outer wall joints 2 having different width dimensions. Specifically, the dimension d from the position of the edge portion on the outdoor side of the opposed surface portions 1a and 1a that are parallel to each other across the space portion in the joint 2 is 2 mm so that the positions are the same depth position. It is fitted in a deep position.

  Thereby, in the joint 2 with a width dimension a of 8 mm shown in FIG. 1 (a) and the joint 2 with a width dimension b shown in FIG. 1 (b) of 10 mm, both end edges of the outermost fin 4 in the gasket 3 are obtained. The portions 4a and 4a are in a state of projecting to the outdoor side from the opposed surface portions 1a and 1a that are parallel to each other across the joint space, but the ends 4a and 4a are bent as described above. By the action of the bending, it is in a state along the surface portions of the chamfered portions 1b and 1b on the outer wall surface. Further, in the joint 2 having a width dimension c of 12 mm shown in FIG. 1 (c), both end edge portions 4a and 4a of the outermost fin 4 in the gasket 3 are opposed to each other on the opposing surface portions 1a and 1a sandwiching the joint inner space portion. Without projecting to the outdoor side from 1a, it is within the parallel facing surface portions 1a, 1a and is in a state of elastically contacting the surface facing surface portions 1a, 1a. Further, since the fin 4 has an R shape that protrudes outwardly from the center portion to both end edge portions, both end edge portions 4a, 4a of the outermost fin 4 in the gasket 3 are in the fitted state of the gasket 3. Even if an external force is applied along the surface portions of the chamfered portions 1b and 1b on the outer wall surface parallel to the opposing surface portions 1a and 1a sandwiching the joint space, the fins 4 are applied even when an external force is applied to form a convex R shape on the indoor side. The joint base can maintain a flat shape.

  Thus, according to the structure of the outer wall joint described above, the depth of the intermediate portion in the width direction of the outermost fin 4 facing the outdoor side of the gasket 3 on the plurality of outer wall joints 2 with different width dimensions. Since the positions are fitted so as to have the same depth position of the depth dimension d, the degree of conspicuousness of the outer wall joint due to the difference in the depth position of the intermediate portion in the width direction of the outermost fin 4 facing the outdoor side There is no difference, and there is no difference in the joint bottom shape due to the difference in joint width, and even if there are a plurality of outer wall joints 2. The design of the outer wall surface is not impaired.

  In addition, since both end edges 4a and 4a of the outermost fin 4 are bent, the gasket 3 has the outermost fin 4 in the state of being fitted into the outer wall joint 2 in relation to the width dimension of the outer wall joint 2. As shown in FIGS. 1 (a) and 1 (b), the fins 4 may be protruded to the outdoor side with respect to the parallel facing surface portions 1a and 1a sandwiching the joint interior space portion. As a result of the bending of the two front edge portions 4a and 4a, the chamfered surface portions 1b and 1b, which are outer wall surfaces, are provided along the chamfered surface portions 1b and 1b.

  In addition, in the outer wall joints having a small width dimension, for example, outer wall joints 2 and 2 as shown in FIGS. 1 (A) and (B), both end edges 4a and 4a of the outermost fin 4 serve as the joint space part. By projecting to the outdoor side from the opposed surface portions 1a, 1a parallel to each other, the leading edge portions 4a, 4a are bent along the chamfered surface portions 1b, 1b by the action of bending, so that FIG. The outer wall joints 2 and 2 having the width dimensions a and b as shown in (b) can be shown as outer wall joints having a larger width dimension, and the width dimension c as shown in FIG. It is possible to make it difficult to feel the difference in the width dimension with the outer wall joint 2, to make the outer wall surface with a good appearance, and to the outer wall joints with the width dimensions a and b shown in FIGS. The same effect can be achieved between 2 and 2.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-described embodiment, both end edge portions 4a and 4a of the outermost fin 4 of the gasket 3 are illustrated with a width dimension projecting to the outdoor side from the opposed surface portions 1a and 1a that are parallel to each other and sandwich the joint space portion. Although the outer wall joints 2 and 2 as shown in FIG. 1 (A) and (B) and the outer wall joint 2 as shown in FIG. Then, both ends edge portions 4a, 4a of the fin 4 on the outermost side of the gasket 3 have a structure in which only the outer wall joints projecting to the outdoor side from the mutually parallel opposing face portions 1a, 1a sandwiching the joint joint space portion are provided on the outer wall surface. It is also possible to apply, and it is also possible to apply to the structure which has only the outer wall joint of the width dimension as shown in FIG. 1 (a) (c) or FIG. 1 (b) (c) in an outer wall surface. .

  Further, as shown in FIG. 4, both end edge portions 4 a, 4 a of the outermost fin 4 protrude to the outdoor side from the mutually parallel facing surface portions 1 a, 1 a sandwiching the joint space portion, and both end edge portions 4a, 4a is along the chamfered surface portions 1b, 1b which are outer wall surfaces by the action of bending, and improves the adhesion to the chamfered surface portions 1b, 1b which are outer wall surfaces of the both end edge portions 4a, 4a, In order to reduce the level difference between the two leading edge portions 4a, 4a and the chamfered surface portions 1b, 1b and to make the step appearing in the joint design inconspicuous by bending both the leading edge portions 4a, 4a, The cross-sectional thickness of the fin 4 may be gradually reduced from the portion to both the tip edge portions 4a and 4a.
