  However, with water sealing by sealing, skill is required to finish to improve the appearance from the outside, so use a joint joint cover with an anchor and embed the anchor part in the sealing material to seal the sealing material Although it is also concealed, the structure in which the anchor portion is embedded in the sealing material may impair the water-stopping performance of the sealing material.

  On the other hand, in the case of water stoppage with a gasket, when the joint width is distorted due to construction errors, the curvature is large when the joint width is small, and the curvature is small when the joint width is large. There is a problem that it ends up.

  In any method, when the joint width changes due to secular change, in the case of a sealing material, the shape of the surface facing the outside changes, or the combination of the sealing material and the decorative joint cover If this is the case, the sealing material behind will be exposed on both sides of the decorative joint cover, the decorative joint cover will be deformed, or in the case of a gasket, the curved state will change, which will deteriorate the appearance of the joint. There is a problem that it may end up.

  In view of the above problems, the present invention provides a dry makeup joint cover structure and a dry makeup joint cover used therefor, which do not deteriorate the appearance of the joint due to joint error due to construction error or secular change. It is an issue to provide.

  Another object of the present invention is to provide a dry-type cosmetic joint cover structure and a dry-type cosmetic joint cover used therefor that can be realized without impairing the water-stopping performance of the water-stopping material behind.

  The above-mentioned problem is that a dry-type cosmetic joint cover is installed on the part of the outer wall joint facing the outside, and the dry-type cosmetic joint cover follows the side cover portion that follows one side of the joint and the other side that sandwiches the joint. Side cover portions and intermediate cover portions in which each side portion on both sides overlaps with each side cover portion and closes between the side cover portions, and the overlap width changes due to the difference in joint width. This is solved by a dry-type joint joint structure characterized in that the cover is kept in a cover state.

Moreover, it is a dry-type makeup joint cover installed on the part facing the outside of the outer wall joint,
A side cover portion that follows one side that sandwiches the joint, a side cover portion that follows the other side that sandwiches the joint, and each side portion on both sides overlaps each side cover portion between the side cover portions. This is solved by a dry-type joint joint cover characterized in that it comprises an intermediate cover portion for closing, and the overlap width changes depending on the joint joint width so as to keep the joint joint.

  In these cover structures and covers, the side cover part and the intermediate cover part on both sides are overlapped, and the overlap width changes due to the difference in joint width, so that the joint is kept in the cover state. The outer surface of the decorative joint cover does not deform in the direction of indentation or bulge, and the water-stopping material behind it is not exposed, and the appearance of the joint deteriorates due to misalignment of the joint due to construction errors or aging. There is no end.

  In the above-described cover structure and cover, the dry-type decorative joint cover is preferably held on the joint part with each side cover part elastically contacting both side parts sandwiching the joint by the elastic restoring force of the elastic means. In this case, the dry cosmetic joint cover can maintain the mounting state without depending on the water-stopping material behind, so that the appearance appearance of the joint is improved without impairing the water-stopping performance of the joint. be able to.

  Since the present invention is as described above, the appearance appearance of the joints is not deteriorated due to the deviation of the joint width due to construction error or secular change. Moreover, it can be realized without impairing the water stop performance of the water stop material behind.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  In the first embodiment shown in FIGS. 1 and 2, 1 and 1 are outer wall materials made of ceramics, etc., 2 is a vertical joint between them, and the joint 2 is an in-situ foamed air-foamed urethane or sealing material. Water-stopping material 3 is used to stop water, and a dry-type cosmetic joint cover 4 is installed adjacent to the water-stopping material 3 on the outdoor side.

  As shown in FIG. 1, the dry makeup joint cover 4 includes a side cover portion 5 that follows the outer wall surface material 1 on one side sandwiching the joint 2, and an outer wall surface material 1 on the other side sandwiching the joint 2. A side cover portion 5 that follows the side cover portions 5 and 5 and an intermediate cover portion 6 that closes the side cover portions 5 and 5 by overlapping each side cover portion 5 and 5 on the outside thereof. These cover portions 5, 5, and 6 are made of, for example, a fluororesin material.

  And the base part 6b is provided in the back side of the intermediate cover part 6 via the space | interval holding | maintenance wall 6a connected with the center part of the width direction, and the outer side of the side cover parts 5 and 5 of both sides Lips 5a and 5a that are bent toward the base portion 6b are provided at the edge of each of the rim portions, and urethane materials 7 and 7 as elastic means are interposed between the lip portions 5a and 5a and the interval holding wall 6a. The side cover portions 5 and 5 on both sides are biased outward by the elastic restoring force of the urethane materials 7 and 7.

  In addition, the water stop materials 8 and 8 by an ept sealer etc. are attached to the outer surface part of the lip | rip parts 5a and 5a of the side cover parts 5 and 5 of both sides.

  As shown in FIG. 2 (a), the above-described dry-type joint joint cover is constructed after the construction of the water-stopping material 3 behind, as shown in FIG. The elastic restoring force of the materials 7 and 7 is thus compressed in the width direction, and in this state, the material 7 is installed in the joint 2 as shown in FIG. Then, the side cover parts 5 and 5 on both sides of the dry-type decorative joint cover 4 are urged outward by the elastic restoring force of the urethane materials 7 and 7 while maintaining the overlap with the intermediate cover part 6, and the outer wall surface material An attached state is formed by elastically abutting against the side surfaces of 1 and 1.

  In addition, if the dry makeup joint cover 4 is struck with the jig 9 from the outdoor side and the installation state is adjusted, a clean installation state can be formed. Also, in this installation process, when the water stop material 3 behind is a sealing material, as shown in FIG. 2 (b), if a dry-type cosmetic joint cover is installed via the insulating sheet material 10, a problem due to three-sided adhesion Occurrence can be prevented.

  In the makeup joint cover structure formed in this way, the side cover part 5 and the intermediate cover part 6 on both sides are overlapped, and even if the joint width is distorted due to construction errors or secular change, Of course, the elastic restoring force of the urethane materials 7 and 7 absorbs the overlapping width between the side cover portions 5 and 5 on both sides and the intermediate cover portion 6 and can keep the joint 2 in the cover state. The outer surface of the dry-type decorative joint cover 4 is not deformed in the indentation or bulging direction, and the water-stopping material 3 is not exposed, so that the appearance of the joint 2 is improved or good. Can be kept

  In addition, in this embodiment, the dry-type cosmetic joint cover 4 is stretched between the outer wall surface materials 1 and 1 by the elastic contact restoring force of the urethane materials 7 and 7 so as to maintain the attached state. The water stop performance of the material 3 is not impaired by the installation of the dry cosmetic joint cover 4.

  Moreover, in this embodiment, since the intermediate cover part 6 is made to hold | maintain in the center part between the side cover parts 5 and 5 of both sides by the urethane materials 7 and 7 used by the pair, Adjustment can be facilitated.

  In the second embodiment shown in FIG. 3, in the dry-type joint joint cover 4, the lip portions 5 a and 5 a of the side cover portions 5 and 5 on both sides serve as elastic means behind the base portion 6 b of the intermediate cover portion 6. When the dry-type decorative joint cover 4 is compressed in the width direction, the plate part 5b is bent in the out-of-plane direction to generate an elastic restoring force, and this elastic contact restoring force attaches to the joint. The state is made to hold. In addition, consideration is given to the water stop material of back by giving the plate part 5b the brazing of the curve to the outdoor side.

  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 embodiment, the case where the urethane materials 7 and 7 and the plate portion 5b are used as means for changing the overlap width between the side cover portions 5 and 5 on both sides and the intermediate cover portion 6 due to the difference in joint width. Although shown, they may be omitted, and the side cover portions 5 and 5 on both sides may be bonded to the side surface portion of the outer wall surface material 1.

  In the above embodiment, the intermediate cover portion 6 is provided outside the side cover portions 5 and 5 on both sides. However, the intermediate cover portion is located on the inner side of the side cover portions on both sides. May be provided.

  Furthermore, although this invention showed the case where it used for the vertical joint of an outer wall, it is also possible to use for the horizontal joint of various places, such as an interstitial trunk difference part.
