The outer wall joint cover material according to the present invention can be applied to the joints of the outer wall of a new building, but it is easy to apply even when repainting the outer wall of an existing building, and many of them. In this embodiment, application to the joints of the outer wall of an existing building will be described as an example.

Examples of the cover material for joints of the outer wall according to the present invention will be described with reference to FIGS. 1 to 3. As shown in FIG. 2A, the outer wall 2 to which the joint cover material 1 (see FIG. 3C) is attached has a siding board 4 attached as an exterior plate to the surface of the base structure 3 of the building. ing.

The exterior plate may be configured such that not the siding board 4 but another type of exterior plate is attached, but in this embodiment, the configuration in which the siding board 4 is attached as the exterior plate will be described.

On the outer wall 2, as shown in FIG. 2A, a gap 9 is formed at the joint of the siding boards 4 adjacent to each other, that is, at the joint 8. Therefore, in the existing building, the caulking material 11 is filled in the gap. This prevents rainwater from entering the underlying structure 3 side.

In this embodiment, as shown in FIG. 3C, the gap 9 of the joint 8 is covered with the joint cover material 1 to improve the appearance of the joint and further improve the waterproof effect against rainwater. Is.

In the present specification, "left and right" refers to the left and right directions when the cross section orthogonal to the longitudinal direction of the gap 9 and the joint cover material 1 is viewed from the front.

Further, in the present specification, the term "horizontal width" is used in relation to the gap 9 and the joint cover material 1 (cover body 13 and lid 14 described later), but the width is the gap 9 and the joint cover material. It is the width in the lateral direction (the left-right direction orthogonal to the longitudinal direction) that crosses each of the longitudinal directions of 1. In particular, the width w of the gap 9 (see FIG. 2A) is also the distance between two siding boards 4 adjacent to each other.

The outer wall joint cover material 1 according to the present invention includes a cover main body 13 as shown in FIGS. 1 (b) and 1 (c) and a lid 14 as shown in FIGS. 1 (a) and 1 (d). 14 is removable inside the cover body 13.

The cover body 13 and the lid 14 are each formed into a long shape (long and thin band shape) by extruding from a resin material such as hard vinyl chloride. The cover body 13 and the lid 14 may have the same length or different lengths from each other.

The cross section of the cover body 13 orthogonal to the longitudinal direction is formed as shown in FIGS. 1 (b) and 1 (c). That is, the cover main body 13 is placed from the groove portion 17 having a substantially concave cross-sectional shape having an opening 18 at the upper end and the left and right edging portions 20 in a state where the cover main body 13 is placed as shown in FIGS. 1 (b) and 1 (c). It is formed integrally.

The groove portion 17 includes a flat bottom wall 21 and left and right side walls 22. The width W of the bottom wall 21 is shown in FIG. 1 (c), and the width W is formed to be substantially the same as or slightly larger than the distance w (small w) of the gap 9 of the joint 8.

It will be described later that a center line 23 (which may be a very thinly applied thin line) is formed on the surface of the bottom wall 21 during extrusion molding so as to extend the center in the width direction in the longitudinal direction. As shown in 3 (a), when the bottom wall 21 is fixed to the base structure 3 by the nail 31, the fixing position is easy to understand.

The left and right side walls 22 stand up from the left and right ends of the bottom wall 21 of the groove portion 17 and become narrower toward the opening edge 19 (in other words, expand from the opening edge 19 of the groove portion 17 toward the bottom wall 21). As shown above, it is formed in a substantially C shape.

As shown in FIGS. 1 (b) and 1 (c), the left and right edging portions 20 have a cross-sectional shape from the left and right opening edges 19 of the groove portion 17 to the left and right outer sides to a position approximately at the height of the bottom wall 21. Is formed by projecting in a convex curved shape like a wing.

As shown in FIGS. 1 (a) and 1 (d), the lid 14 is integrally formed from a curved top portion 27 and left and right side surface portions 28 extending from the top portion 27, and is orthogonal to the longitudinal direction. The cross-sectional shape to be formed is substantially ∩-shaped as a whole (however, to be exact, the left and right side surface portions 28 extend from the top portion 27).

As shown by the arrows in FIG. 1 (d), the left and right side surface portions 28 are preferably elastically deformable when pressed toward the center so as to be close to each other. The cross-sectional shape orthogonal to the longitudinal direction of the top portion 27 may be another shape, for example, a flat shape, a substantially Π-shaped shape, or the like.

In FIGS. 1 (c) and 1 (d), the width interval S'of the top portion 27 of the lid 14 is substantially the same as the width S'of the opening 18 of the groove portion 17 of the cover body 13. Further, the width W'between the lower ends of the left and right side surface portions 28 of the lid 14 is formed to be larger than the width S of the opening 18 of the groove portion 17 of the cover main body 13.

More specifically, the width W'will be described later, but in a state where the lower ends of the left and right side surface portions 28 of the lid 14 are pressed so as to be close to each other and elastically deformed, the width W'is formed from the opening 18 of the groove portion 17 of the cover body 13. The size should be such that it can be fitted in the groove portion 17.

With such a configuration, as shown in FIG. 3B, the left and right side surface portions 28 of the lid 14 are pressed toward the center so as to be close to each other and elastically deformed to cover the cover. It can be fitted in the groove 17 of the main body 13.

Then, as shown in FIG. 3C, the left and right side surface portions 28 of the lid 14 are elastically contacted with the inside of the groove portion 17 of the cover main body 13 (more specifically, elastically with the inner surface of the side wall 22 of the groove portion 17). ) It is fitted in the state.

The operation and the like of the joint cover material 1 for the outer wall according to the present invention having the above configuration will be described below with reference to FIGS. 1 to 3 together with the construction for attachment to the outer wall 2.

In order to attach the joint cover material 1 to the joint 8 when repainting the outer wall of the existing building, first, the caulking material 10 is formed in the gap 9 of the joint 8 as shown in FIG. 3 (a). Fill. In this case, especially in the case of an existing building, the outside of the already filled old caulking material 11 is filled (additional hitting) by adding a new caulking material 12 as shown in FIG. 2 (b). The caulking material 10 having a flat outer surface is formed.

However, even in the case of an existing building, the old caulking material 11 may be removed and then only the new caulking material may be filled in the gap 9 of the joint 8 to form the caulking material 10. When the outer wall is newly painted when the building is newly constructed, the new caulking material is filled in the gap 9 of the joint 8 to form the caulking material 10.

Next, as shown in FIG. 3B, the cover main body 13 is brought into contact with the outer surface side of the caulking material 10 filled in the gap 9 of the joint 8, and the nail 31 is placed on the center line 23 of the bottom wall 21 ( (See FIG. 1 (c)) At positions spaced in the longitudinal direction, the bottom wall 21 and the caulking material 10 are pierced and driven into the base structure 3, and as shown in FIG. 3 (b). The cover body 13 is fixed to the base structure 3.

In this state, as shown in FIG. 3B, the bottom wall 21 is fixed to the base structure 3 of the building with nails 31 via the caulking material 10 filled in the gap 9 of the joint 8, and the left and right sides are fixed. As shown in FIG. 3B, the lower ends of the edging portions 20 abut on the outer surfaces of the left and right siding boards 4 along the left and right edges 30 of the gap 9.

Next, the lid 14 is fitted into the groove 17 of the cover body 13. Specifically, as shown by the arrow in FIG. 1 (d), the cover main body 13 is contracted by pushing the left and right side surface portions 28 of the lid 14 in a direction slightly closer to each other from the left and right against the elasticity. Fits into the groove 17 from the opening 18 of the.

Then, as shown in FIG. 3C, the left and right side surface portions 28 of the lid 14 elastically abut on the inner surfaces of the left and right side walls 22 of the groove portion 17 of the cover main body 13, and the lower end thereof is the cover main body 13. It is fitted until it comes into contact with the bottom wall 21 of the.

As described above, as shown in FIG. 3C, the joint cover material 1 is attached so as to cover the gap 9 of the siding board 4, that is, the gap 9 of the joint 8 and the outside of the caulking material 10.

In the structure in which the joint cover material 1 is attached to the outer wall 2 in this way, the left and right edging portions 20 are brought into contact with the outer surfaces of the left and right siding boards 4 along the left and right edges 30 of the gap 9, respectively, and the cover main body is formed. The lid 14 is fitted in the groove portion 17 of 13.

According to the joint cover material 1 for the outer wall according to the present invention, the gap 9 and the caulking material 10 of the joint 8 of the outer wall 2 are completely covered by the joint cover material 1, so that the appearance of the outer wall 2 looks good. It improves and the caulking material 10 is covered and protected, so that its deterioration is suppressed.

When the outer wall 2 is painted, the joint cover material 1 can be painted together with the siding board 4 in a state where the joint cover material 1 is attached to the outer wall 2, so that the painting becomes easier and the joint cover material 1 is the siding board 4. The appearance of the outer wall 2 after painting is also good in appearance.

Further, since the gap 9 of the joint 8 is covered with the joint cover material 1 in addition to the caulking material 10, it is possible to further suppress the infiltration of rainwater toward the base structure 3 and suppress the corrosion of the base structure 3 and the like. The effect is produced.

At the joint in the series direction of the cover body 13, the caulking material 10 is exposed, rainwater easily enters, and the appearance is bad. However, if the lid 14 is fitted to the cover body 13 so as to cover this joint, the joint is exposed. Without doing so, rainwater intrusion is prevented and the appearance is improved.

By the way, since the joint cover material 1 according to the present invention has an extremely simple structure, its production can be performed by extrusion molding without requiring a complicated process.

The outer wall 2 can be attached to the joint 8 by a simple process as described above, and the lid 14 can be easily removed from the cover main body 13, and the cover main body 13 can also be easily removed from the joint 8. Maintenance such as repair and repair of 2 is easy, and work efficiency at the site is improved.

Although the embodiment for implementing the joint cover material for the outer wall according to the present invention has been described above based on the examples, the present invention is not limited to such an embodiment and is the scope of the utility model registration claim. It goes without saying that there are various examples within the scope of the technical matters described in.

Since the outer wall joint cover material according to the present invention has the above-mentioned configuration, it can be applied not only as an exterior plate to a siding board but also as a cover material for an outer wall joint made of another exterior plate.
