Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a bottom joint material for siding joint sealing, which fills a gap between a plurality of sidings used for an outer wall of a building, and can be used for an outer wall of a building.

[Conventional technology]

Conventionally, joints generated between sidings used for the outer wall of a building have been closed by filling a caulking material such as urethane for waterproofing.

[Problems to be solved by the invention]

However, in the siding joint seal using only the caulking material, if the caulking material is improperly constructed or changes with time, the waterproof performance is extremely deteriorated and the joint sealing cannot be performed. In addition, since the joint gap is filled only with the caulking material, a large amount of caulking material is used, which deteriorates workability and increases costs. Further, since the joint is dented due to the thinning of the caulking material, there is a problem that the appearance is impaired.

An object of the present invention is to provide a bottom joint material for a siding joint seal, which does not impair the waterproof performance even if the caulking material is poorly constructed or changes with time.

[Means for solving problems]

The present invention has a double structure in which not only caulking material but also bottom joint material is added to a siding joint seal for blocking joints formed between a plurality of sidings attached to the outer wall of a building, so that the caulking material should have a double structure. It was made paying attention to the fact that the above-mentioned object can be achieved by the waterproof power of the bottom joint material even if the waterproof performance is deteriorated.

In the present invention, the bottom joint material is a rigid member integrally formed in a substantially T-shape and provided with a joint core for elastic member positioning, and a notch for positioning to which the joint core of the hard member is fitted. And an elastic member which is formed under the condition that the siding is formed thinner than the thickness of the siding, and a sealer interposed between contact surfaces of the elastic member with each siding and sealing between the elastic member and the siding. It is configured.

[Action]

The waterproofing function of the present invention having such a structure is primarily achieved by the caulking material, and further by the bottom joint material which seals the gap between the siding and the sealer.
It is done next. Therefore, even if the caulking material is poorly constructed or changes with time, the bottom joint material maintains the waterproof property and prevents the extreme deterioration of the waterproof performance.

The bottom joint material also serves as a backup material, reducing the amount of caulking material used and improving workability. Since the amount of the caulking material used is small, the caulking material becomes thin and the joint is not dented.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the building frame 10 has an outer wall foundation plywood 11
And a furring strip 12 attached to the outer wall base plywood 11. At the center position of the outer surface of the furring strip 12, a bottom joint material 13 is positioned and fixed along the longitudinal direction thereof via a double-sided adhesive layer 14. The sidings 15 are attached in accordance with the siding contact surfaces 13A provided on both sides in the longitudinal direction on the outside of the bottom joint material 13, and the furring joint material 12 side of the joint 16 generated between the sidings 15 is the bottom joint material 13. Sealed by. Furthermore, the outside of the bottom joint material 13 of the joint 16 is
It is sealed by being filled with the urethane caulking material 17.

The bottom joint material 13 is, as shown in an enlarged scale in FIG.
A hard member 18 having a joint core 18A integrally formed in a substantially T shape by a PVC (vinyl chloride) molded product
An elastic member having a substantially V-shaped notch 19A into which the joint core 18A of the hard member 18 is inserted and which is formed on the strip by EPDM (ethylene-propylene-diene terpolymer) sponge.
19 and a butyl sealer 20 interposed on a siding contact surface 13A that contacts each siding 15 of the elastic member 19. Further, the outer surface 19 of the elastic member 19
B is mold-release treated with silicone or the like.

In the present embodiment having such a configuration, as shown in FIG. 3, the bottom joint material 13 is attached to the furring material 12 which is a part of the building body 10 of the building.
A squeeze line 21 for positioning the
The bottom joint material 13 is fixed in accordance with. The fixing of the bottom joint material 13 is performed through the double-sided adhesive layer 22 which is adhered to the body side of the bottom joint material 13 in advance. Further, by contacting the siding 15 with the siding contact surface 13A of the bottom joint material 13 via the butyl sealer 20, the gap between the bottom joint material 13 and the siding 15 is sealed, and the furring material of the joint 16 is joined. 12
The side is filled. The outside of the bottom joint material 13 of the joint 16 is
It is sealed by filling with urethane caulking material 17.

According to this embodiment, the joints between the sidings 15 are
Not only the urethane caulking material 17 but also the bottom joint material 13 that seals between the siding 15 with the butyl sealer 20 has a double structure for the 16 seals. Even if occurs, the bottom joint material 13 does not cause an extreme decrease in waterproof performance. At this time, since the bottom joint material 13 and the caulking material 17 are subjected to a mold release treatment with silicone or the like, the bottom joint material 13 is not affected by the temporal change of the caulking material 17 or the like.

On the other hand, since the bottom joint material 13 also serves as a backup material, it is possible to reduce the amount of the urethane caulking material 17 used.
The workability is improved and the cost is reduced. Further, the dent of the joint 16 due to the thinning of the urethane caulking material 17 is improved, and the appearance is not impaired.

Further, the joint portion 18A of the hard member 18 is cut into the joint portion 19A of the elastic member 19.
The elastic member 19 can be easily positioned by simply fitting the elastic member 19 to the elastic member 19 because the joint core 18A is hard.
Even if a force is applied to the elastic member 19, the elastic member 19 can be reliably positioned. This makes it possible to secure a neat fit as a whole.

Furthermore, since a part of the hard member 18 of the bottom joint material 13 is sandwiched between the furring strip 12 and the siding 15, the bottom joint material 13 can be fixed more firmly. In addition, the bottom joint material 13 is a hard member 18
Since it is fixed by sticking on the body side, elastic member 19
It can be mounted easily and accurately as compared with the case of fixing.

In the above embodiment, the elastic member 19 of the bottom joint material 13 is made of EPDM.
Although a sponge is used, the material is not limited to this material, and other elastic members such as chloroprene rubber (CR) and silicone rubber may be used. Further, although the hard member 18 is a vinyl chloride molded product, other resin such as nylon, metal material such as aluminum, or other hard member may be used. Also, the caulking material 17 is not limited to urethane.

Further, the shapes of the siding 15, the furring strip 12 and the like are not limited to the shapes of the embodiments.

[Effect of device]

According to the present invention as described above, even if the caulking material is poorly constructed or aged, the waterproof performance is not impaired. Further, since the bottom joint material is composed of the hard member having the joint core and the elastic member, there is an effect that the elastic member can be surely positioned by the joint core and a neat fit can be secured.

Regarding the present invention, when a so-called Patrice search was conducted using IPC as E04B 1/68 and the keyword as "joint material", a joint material composed of a hard member and a elastic member having a joint core like the present invention was found. Instead, the novelty of the present invention in the relevant field became clear.
