Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field related to a joint structure of an exterior material having excellent workability and designability and a method of performing the same.

[0002]

2. Description of the Related Art In recent years, siding materials that can shorten the construction period by dry-type construction, have a wide variety of products, and are excellent in workability have been widely used as exterior materials for buildings. Are impressed with their excellent design.

[0003] When this siding material is applied, a sealing material is previously provided on the plate material at the connection portions of the siding materials that are adjacent in the vertical direction (up-down direction), so that waterproof treatment is not required. However, with respect to the connection portions of the siding materials adjacent to each other in the left-right direction, after waterproofing the siding material to the base, a waterproofing treatment is performed with a polyurethane-based or modified silicone-based sealing material. This kind of sealing material requires a function of expanding and contracting to some extent in response to the movement of the plate material and the base material. If the width of the sealing material is too narrow, the absolute amount of elongation becomes small, so a width of at least about 10 mm is required. Needed.

[0004]

By the way, in the case of an exterior material having a tile or brick-like pseudo joint formed on the surface, the difference between the pseudo joint and the joint between the plate materials is reduced to make the appearance less noticeable. In order to enhance the property, it is necessary to form a pseudo joint on the surface of the plate material to a width corresponding to the joint width between the plate materials, but if the width of the vertical joint between the horizontally adjacent plate materials is large as described above, For the purpose of making the vertical joints inconspicuous by the pseudo joints, the width of the pseudo joints must be increased in accordance with the vertical joints, and fine pseudo joints cannot be formed. As a result, not only is there a limitation in terms of the design of the exterior material, but also a problem arises in that the strength of the exterior material is reduced by the wide pseudo joints.

[0005] The present invention has been made in view of the above points, and an object of the present invention is to fix a plurality of exterior members having pseudo joints formed on the surface as described above to form an exterior surface. In this case, by improving the joint structure between the exterior materials adjacent to each other in the horizontal direction, it is possible to secure a stable sealing property and waterproofness at the joints regardless of the movement of the exterior material and the base material, and thus the exterior material An object of the present invention is to make it possible to reduce the width of the pseudo joint formed on the surface to secure an increase in the strength of the exterior material, to eliminate restrictions on the design of the exterior material, and to improve the workability.

[0006]

In order to achieve the above object, according to the present invention, a joint material having elasticity and waterproofness is bonded in advance to a lateral end surface of a sheathing material, and the jointing condition of the sheathing material is determined. Sealing the joint portion in a state where the joint material is compressed between the lateral end face of the adjacent exterior material, and the width of the joint material in the compressed sealing state is substantially the same as the pseudo joint of the exterior material surface. I did it.

More specifically, according to the invention of claim 1, a plurality of exterior members having pseudo joints of a predetermined width provided on the outer wall surface of the building are fixed in a state where they are arranged vertically and horizontally. It is premised on the joint structure of the exterior material in which a material exterior surface is configured and a gap is formed at least between the exterior materials adjacent in the horizontal direction to form vertical joints.

A joint material having elasticity and waterproofness and having a width larger than that of the pseudo joint is bonded to one lateral end face of the exterior material in advance, and the exterior materials are adjacent to each other in the lateral direction. In the state where the joint material is fixed to the outer wall surface of the building, the joint material adhered to one of the exterior materials adjacent in the lateral direction is in close contact with the lateral end surface of the other exterior material, and is formed by the joint material. The finished width of the vertical joint is set to be substantially the same width as the pseudo joint.

According to the above configuration, since the vertical joint between the exterior materials adjacent to each other in the horizontal direction and the pseudo joint provided on the surface of the exterior material have substantially the same width, it is possible to distinguish the two joints from the outside in appearance. It is not possible to obtain an integrated appearance as a whole exterior surface despite the fact that the exterior surface of the building is composed of a plurality of exterior materials.

Further, since the joint material is previously bonded to one lateral end surface of the exterior material, it is only necessary to abut the exterior materials when constructing the exterior material, and the sealing material is later sealed in the gap between both exterior materials. The work of inserting the material is unnecessary, and the workability of the exterior material is excellent.

Further, the joint material between the two exterior materials adjacent to each other in the lateral direction has elasticity and waterproofness and is compressed and deformed in the gap between the two exterior materials. On the other hand, joints of joint material do not break, and joints excellent in waterproofness can be obtained.

Also, since the width of the joint material between the exterior materials adjacent in the horizontal direction is substantially the same as the width of the pseudo joint on the surface of the exterior material, the width of the vertical joint between the exterior materials, and thus the pseudo surface of the exterior material, The width of the joint can be reduced, and accordingly, the strength of the exterior material can be increased, and the design limitation of the exterior material can be reduced.

According to the invention of claim 2, on the outer wall surface of the building,
A plurality of horizontally long exterior materials provided with pseudo joints of a predetermined width on the surface are arranged in a vertical direction, and of these exterior materials, an exterior material adjacent in the vertical direction is located at a lower end of the upper exterior material. The female part and the male part at the upper end of the lower exterior material are fixed to the outer wall surface in a fitted state, while the exterior material adjacent to the lateral direction is the female part of one exterior material. And an outer member fixed to the outer wall surface in a state where the male member of the other outer member is fitted to the outer surface, and a gap is formed between the outer members on the surface side of the fitting portion to form a vertical joint. The joint structure is assumed.

A joint material having elasticity and waterproofness and having a width larger than that of the pseudo joint is bonded to one lateral end face of the exterior material in advance. In the state where the joint material is fixed to the outer wall of the building, the joint material adhered to one of the exterior materials adjacent in the lateral direction adheres to the lateral end surface of the other exterior material, and is formed by the joint material. The finished width of the vertical joint is set to be substantially the same width as the pseudo joint.

With this configuration, the function and effect of the first aspect of the invention can be more specifically expressed. Moreover, since the exterior materials vertically adjacent to each other are fitted in the female part and the male part, the workability and waterproofness are further improved. In addition, a metal fitting for locking the female part and the male part can be used, so that the nails are not visible in appearance, the appearance is improved, and the workability is improved.

Further, the female part of one of the exterior members adjacent in the lateral direction is fitted to the male part of the other exterior material, and the joint material is inserted into the gap between the exterior materials on the front surface side of the fitting part. Since the joints are arranged and vertical joints are formed, the joints do not communicate directly with the ground, and are excellent in waterproofness. It does not pass through and has excellent fire protection.

The invention of claim 3 is an invention of a method of applying an exterior material. In this invention, at least a plurality of exterior materials having a pseudo joint having a predetermined width provided on the surface of an exterior wall of a building are provided. It is premised on a method of constructing an exterior material that is fixed so that a gap is formed between exterior materials adjacent in the horizontal direction to form vertical joints and forms an exterior surface.

Then, a joint material having elasticity and waterproofness and having a width larger than that of the pseudo joint is bonded to one lateral end face of the exterior material in advance, and the exterior materials adjacent to each other in the lateral direction are bonded to each other. When fixed to the outer wall of the building, the joint material adhered to one of the exterior materials adjacent in the lateral direction is in close contact with the lateral end surface of the other exterior material, and the vertical joint formed by the joint material is It is characterized in that the finished width is fixed to be substantially the same width as the pseudo joint. In the present invention, the above-mentioned claim 1 is also provided.
The same operation and effect as those of the invention can be obtained.

And a male member 4 at the upper end of the lower exterior material 1 is fitted to the base material of the outer wall surface in a mating structure.

On the other hand, as for the outer packaging materials 1 and 1 which are adjacent to each other in the horizontal direction, the right lateral end face 8 of the left exterior material 1 and the left lateral end face 7 of the right exterior material 1 opposed thereto are vertically interposed between them. A vertical joint 10 is formed between the lateral end surfaces 7 and 8 of the both exterior materials 1 and 1.

Furthermore, the right lateral end face 8 of the exterior material 1
The joint material 12 having elasticity and waterproofness is adhered to the left lateral side end surface 7 (may be an adhesive method other than the adhesive method). The joint material 12 is made of, for example, a foam of EDPM (ethylene propylene rubber), and is cut into a shape corresponding to the lateral end surface 8 of the exterior material 1 to be attached. Butylene adhesive is applied. Although not shown, the pressure-sensitive adhesive is covered with a separator (release paper) in a state where the pressure-sensitive adhesive is not adhered to the exterior material 1. After the separator is peeled off, the adhesive surface is attached to the lateral end surface 8 of the exterior material 1. It is supposed to.

As shown in FIGS. 4 and 5, the joint material 12 is left as it is, that is, the joint material 12 is simply attached to the exterior material 1 without fixing the exterior material 1 to the outer wall surface of the building. In the state where only the dummy joint 2 is present, the dummy joint 2 has a width W1 larger than the width W of the pseudo joint 2 on the surface of the exterior material 1 (or the width of the vertical portion when the width of the vertical portion and the horizontal portion of the pseudo joint 2 is different).

In the state where the exterior materials 1 and 1 are fixed to the foundation of the outer wall surface of the building adjacent to each other in the lateral direction, FIGS.
As shown in FIG. 3, the joint material 12 adhered to the right lateral end face 8 of the left exterior material 1 adjacent in the lateral direction is tightly compressed on the left lateral end face 7 of the right exterior material 1, Both exterior materials 1, 1 formed by the compressed joint material 12
The finished width W2 of the vertical joint 10 is the width W of the pseudo joint 2
Is almost the same as

When the exterior materials 1, 1,... Are formed in order to form such a joint structure, the joint material 12 is attached to the right lateral end face 8 of each exterior material 1 in advance. Next, when fixing a plurality of exterior materials 1, 1,... To the lower ground of the outer wall surface of the building, exterior materials 1, 1,. And the joint material 1 stuck on the right side end surface 8 of the left exterior material 1
2 is the left lateral end face 7 of the right exterior material 1 to be fixed next
So that the finished width W2 of the vertical joint 10 formed by the joint material 12 between the two lateral end surfaces 7 and 8 is substantially the same as the width W of the pseudo joint 2 on the surface of each exterior material 1. Fix it.

Therefore, in this embodiment, the width of the vertical joint 10 between the horizontally adjacent exterior materials 1, 1 among the plurality of exterior materials 1, 1, ... fixed to the outer wall surface of the building. W2 and pseudo joint 2 provided on the surface of each exterior material 1
Are substantially the same as each other, as shown in FIG. 1, on the exterior surface of a building composed of a plurality of exterior materials 1, 1,. The difference is very small. Therefore, although the exterior surface is composed of a plurality of exterior materials 1, 1,..., An integrated appearance as if one large exterior material was used as the entire exterior surface is obtained.

Further, since the joint material 12 is previously adhered to the right lateral end face 8 of the exterior material 1, when the exterior material 1 is constructed, the exterior materials 1, 1 adjacent to each other in the lateral direction as described above are not attached to each other. Automatically matches both exterior materials 1,1 just by matching each
Vertical joints 10 are formed between them. For this reason, the joint material 1
As in the case where there is no outer material 2, after the outer material 1 is fixed,
The work of forming the vertical joint by inserting the sealing material into the gap between the spaces becomes unnecessary, and the workability of the exterior material 1 can be improved.

Further, the joint material 12 between the exterior materials 1 and 1 has elasticity and waterproofness and is compressed and deformed in the gap between the exterior materials 1 and 1, so that the base material and Even if the exterior material 1 itself moves, the joint material 1
2 expands and contracts in the width direction, and the gap between the exterior materials 1 and 1 is the joint material 1
2, the joints 12 are stably closed, the joints 12 do not break, and the vertical joints 10 having excellent sealing properties and waterproofness can be stably obtained.

Moreover, the exterior members 1, 1 vertically adjacent to each other are fitted in a mating structure of the female part 5 at the lower end of the upper exterior material 1 and the male part 4 at the upper end of the lower exterior material 1. Therefore, the workability and waterproofness can be further improved. In addition, a predetermined metal fitting for locking the female real part 5 and the male real part 4 can also be used. In this case, the appearance is improved without visible nails, and the workability is further improved. .

In the construction state of the exterior material 1, the width W2 of the joint material 12 between the exterior materials 1 and 1 adjacent in the lateral direction is substantially the same as the width W of the pseudo joint 2 on the surface of the exterior material 1. The width W of the pseudo joint 2 on the surface of the exterior material 1 as well as the width of the vertical joint 10 between the exterior materials 1 and 1 can be reduced. For this reason, it is possible to secure an increase in the strength of the exterior material 1 and reduce design restrictions on the exterior material 1.

If the color of the joint material 12 is arranged so as to match the color of the pseudo joint 2 on the surface of the exterior material 1, the difference between the pseudo joint 2 and the vertical joint 10 can be made less noticeable.

Further, in the above embodiment, the exterior materials 1 and 1 vertically adjacent to each other are fitted by the mating structure of the male part 4 and the female part 5, but instead, the outer material 1 and the female part 5 are fitted in the horizontal direction. Joints may be formed in the same manner as between adjacent exterior materials 1 and 1.

Further, in the above embodiment, the joint material 1 adhered on one side to the right lateral end face 8 of the left exterior material 1.
2 has a structure in which the other side surface of the joint material 12 is simply adhered to the left lateral end surface 7 of the right exterior material 1. It may be. In this way, the expansion and contraction of the joint material 12 is reliably performed in response to the change in the gap between the exterior materials 1 and 1, and the sealing performance and the waterproofness can be further improved. At this time, for example, an adhesive may be applied to the other side surface of the joint material 12 and covered with release paper or the like, and the release paper may be peeled off and adhered at the time of construction.
