Japanese Patent Application Laid-Open No. 2003-343024

In recent years, with the improvement of the heat insulating performance of a house, a method of providing a ventilation layer between the inside of the outer wall material and the base material to remove the moisture in the wall has become common. However, in the invention described in Patent Document 1, since the outer wall material is brought into contact with the joiner's substrate and the ridges, it is not possible to provide a ventilation layer between the inside of the outer wall material and the base material. Further, in the invention described in Patent Document 1, since the outer wall material is attached so as to cover the side surface of the ridge of the joiner, ventilation cannot be performed between the inside and the outside of the ridge.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a joiner capable of ventilating between the inside and the outside of the joiner. Another object of the present invention is to provide a joint structure of an outer wall material capable of providing a ventilation layer between the inside of the outer wall material and the base material and allowing ventilation between the inside of the joiner and the ventilation layer.

In order to solve the above problems, the joiner according to the present invention is formed by bending an elongated plate-shaped member along the longitudinal direction, and is formed in the longitudinal direction at a joint portion of two outer wall materials arranged side by side in the longitudinal direction. Is a joiner provided substantially along the vertical direction, and has a convex portion having a pair of side surfaces and a base portion provided on both left and right sides of the convex portion, and the base portion is provided on at least one of the side surfaces. It is characterized in that a hole penetrating the side surface is provided adjacent to the bent portion. This allows ventilation between the inside and outside of the joiner.

A plurality of the holes may be provided along the bent portion. This makes it possible to increase the air permeability.

In order to solve the above problems, in the joining structure of the outer wall material according to the present invention, the outer wall material of the building is fixed to the base material via a spacer, and the outer wall materials are arranged side by side. It is a joint structure of an outer wall material provided with a joiner in a portion, and the joiner is formed by bending an elongated plate-shaped member along a longitudinal direction, and has a convex portion having a pair of side surfaces and the convex portion. The joiner has bases provided on both the left and right sides of the base material, and the joiner is fixed to the base material so that the longitudinal direction is substantially along the longitudinal direction, and the spacer is superimposed on the base or on the base. Adjacently fixed to the base material, the outer wall material is fixed to the spacer so that the end face abuts on the side surface, and seals the seam of the outer wall material so as to cover the top of the convex portion. A material is filled, and a ventilation layer, which is a space for ventilation, is formed between the base material, the outer wall material, and the joiner, and at least one of the side surfaces thereof is a base. A hole penetrating the side surface is provided adjacent to the bent portion of the siding portion, and the hole is characterized in that the internal space of the convex portion and the ventilation layer are communicated with each other. As a result, a ventilation layer can be provided between the inside of the outer wall material and the base material, and ventilation can be performed between the inside of the joiner 1 and the ventilation layer.

A plurality of the holes may be provided along the bent portion. This makes it possible to increase the air permeability.

The height of the upper end portion of the hole from the base material may be equal to or less than the height at which the spacer protrudes from the base material. As a result, it is possible to improve the air permeability while preventing the joiner from decreasing in strength.

According to the present invention, a ventilation layer can be provided between the inside of the outer wall material and the base material, and ventilation can be performed between the inside and the outside of the joiner.

Hereinafter, the joint structure of the joiner and the outer wall material of the present invention will be described in detail with reference to the drawings. The joiner of the present invention is provided at a joint portion of two outer wall materials arranged side by side so that the longitudinal direction is substantially along the vertical direction.

1A and 1B are views showing an outline of Joiner 1 according to an embodiment of the present invention, FIG. 1A is a perspective view, FIG. 1B is a view taken along the longitudinal direction, and FIG. 1C is a view taken along the longitudinal direction. It is a figure seen from the direction substantially orthogonal to the longitudinal direction.

The joiner 1 is formed by bending an elongated plate-shaped member along the longitudinal direction. Although the joiner 1 is formed by using a metal plate such as a steel plate or an aluminum plate, a resin plate material may be used.

The joiner 1 is a so-called hat-shaped joiner having a hat-like shape when viewed along the longitudinal direction, and mainly has a base portion 13 and a convex portion 15. The convex portion 15 corresponds to a hat-shaped central convex, and the base 13 corresponds to a hat-shaped brim.

Hereinafter, the direction along the longitudinal direction of the joiner 1 is defined as the z direction, and the direction in which the convex portion 15 rises is defined as the + x direction. Further, the direction substantially orthogonal to the x direction and the z direction is defined as the y direction.

The convex portion 15 has a pair of side surfaces 11 and a tip surface 12. The side surface 11 extends along the xz plane, and the front end surface 12 extends along the yz plane. The pair of side surfaces 11 face each other, and the tip surface 12 connects the pair of side surfaces 11.

The base portion 13 has a flat plate shape, is provided on both the left and right sides (+ y side and −y side) of the convex portion 15, and extends along the yz plane. The base portion 13 extends outward in the left-right direction from the bottom surface side of the convex portion 15. The bottom surface side is the opposite side of the tip end side (the side on which the tip end surface 12 is provided).

In the present embodiment, the angle formed by the base portion 13 and the side surface 11 and the angle formed by the side surface 11 and the tip surface 12 are substantially right angles, but the angle is not limited to a substantially right angle. Further, in the present embodiment, the tip surface 12 is a flat surface, but the tip surface 12 may be a curved surface.

The side surface 11 is provided with a hole 14 penetrating the side surface 11 adjacent to the bent portion 11a with the base portion 13. In the present embodiment, the holes 14 are round holes, and a plurality of holes 14 are provided along the bent portion 11a. The holes 14 may be provided on at least one of the two side surfaces 11.

Next, the joining structure 2 of the outer wall material using the joiner 1 will be described. FIG. 2 is a perspective view showing an outline of the joint structure 2 of the outer wall material using the joiner 1. In FIG. 2, for the sake of explanation, a part of the joint structure 2 of the outer wall material (for example, the outer wall material 21 on the right side (−y side)) is omitted.

In the joint structure 2 of the outer wall material according to the present invention, the outer wall material 21 of the building is fixed to the base material 23 via the spacer 22, and the joiner 1 is attached to the joint portion of the outer wall material 21 arranged side by side. It is provided.

The outer wall material 21 is a plate-shaped member (siding) used for the outer wall of the building. The base material 23 is provided with a moisture permeable waterproof sheet on the outer surface (the surface on the + x side) of the heat insulating material and the studs.

The joiner 1 is provided so that the longitudinal direction (z direction) is substantially along the vertical direction. The joiner 1 is fixed to the base material 23.

The spacer 22 is a so-called ventilation fastener. The spacer 22 is fixed to the base material 23 so as to be superimposed on the base 13 or adjacent to the base 13. The height h2 of the spacer 22 in the x direction is lower than the height h1 of the convex portion 15 in the x direction. Here, the height in the x direction is the height protruding from the base material 23 (hereinafter, simply referred to as "height"). The spacer 22 is not limited to the ventilation fastener, but may be a wooden bar (ventilation furring strip) or the like.

The outer wall material 21 is fixed to the spacer 22 so that the end surface abuts on the side surface 11. In the present embodiment, the outer wall material 21 is fixed to the metal fitting portion 22a provided on the + x side surface of the spacer 22, but for example, when the ventilation furring strip is the spacer 22, it is extended in the horizontal direction. A metal fitting may be provided on the + x side surface of the ventilated furring strip, and the outer wall material 21 may be attached to the metal fitting, or the outer wall material 21 may be fixed to the ventilated furring strip by a nail or the like.

Since the outer wall material 21 is provided on the spacer 22, a gap (ventilation layer) is provided between the outer wall material 21 and the base material 23. Further, since the length of the spacer 22 in the z direction is much shorter than the length in the longitudinal direction (z direction) of the joiner 1, most of the side surface 11 of the joiner 1 is exposed to the ventilation layer.

In the state where the outer wall material 21 is provided on the spacer 22, the sealing material 24 is filled in the seam of the outer wall material 21 so as to cover the top portion (tip surface 12) of the convex portion 15.

FIG. 3 is a cross-sectional view showing an outline of the joint structure 2 of the outer wall material using the joiner 1. FIG. 3 is a cross-sectional view taken along the line passing through the center of the hole 14. In FIG. 3, the spacer 22 is not shown.

A ventilation layer S, which is a space for ventilation, is formed between the base material 23, the outer wall material 21, and the joiner 1. Dew condensation can be prevented by allowing air to pass through the ventilation layer S. Further, even if the outer wall material 21 is exposed to direct sunlight and the temperature rises, warm air flows from the bottom to the top in the ventilation layer S, so that the temperature rise in the building can be prevented.

Since the hole 14 is provided adjacent to the bent portion 11a with the base portion 13, the hole 14 communicates the internal space of the convex portion 15 with the ventilation layer S. As a result, ventilation can be performed between the ventilation layer S and the ventilation layer S (see the thick arrow in FIG. 3).

In the present embodiment, the height h3 of the hole 14 (that is, the height of the upper end portion of the hole 14 from the base material 23) is equal to or less than the height h2 of the spacer 22. If the hole 14 is larger than the height of the spacer 22, a part of the hole 14 will be covered with the outer wall material 21, and the hole 14 will be wasted. Further, if the hole 14 is too large, the strength of the joiner 1 may be lowered. Therefore, it is desirable that the height h1 of the hole 14 is set to the height h2 or less of the spacer 22.

FIG. 4 is a cross-sectional view showing an outline of the joint structure 2 of the outer wall material at the corner of the building at the corner of the building. FIG. 4 is a cross-sectional view of a line passing through the center of the hole 14 (not shown), similarly to FIG. 3, and the spacer 22 is not shown.

Since the joiner 1 is provided adjacent to the corner of the building, the ventilation layer S is formed along the corner of the building. Therefore, ventilation can be performed between the ventilation layers S along two adjacent surfaces via the ventilation layer S arranged at the corner of the building (see the thick arrow in FIG. 4).

FIG. 5 is a diagram schematically showing the wall surface of a house adopting the joint structure 2 of the outer wall material. In FIG. 5, the air flow (main part only) is indicated by an arrow. The house is provided with a plurality of ventilation layers S1 to S6. When the house is irradiated with sunlight from the upper left direction of the paper surface (see the two-dot chain arrow) in FIG. 5, the temperature of the wall surface covering the ventilation layers S1 and S2 tends to rise.

Since the ventilation layer S1 is in contact with the roof of the ventilation layer S1, warm air is discharged from the upper part of the ventilation layer S1 and cold air enters from the lower part of the ventilation layer S1 to enable ventilation. On the other hand, in the ventilation layer S2, most of the upper part is blocked by the window, and it is difficult to discharge the warm air that has risen inside the ventilation layer S2. In the present embodiment, since the hole 14 is provided in the joiner 1, the air in the ventilation layer S2 is discharged to the joiner 1, and the warm air rises in the joiner 1 and is exhausted from the upper end portion of the joiner 1. This makes it easier for warm air to be exhausted. Further, if the holes 14 are provided on the side surfaces 11 on both sides of the joiner 1, the air in the ventilation layer S2 can be exchanged between the ventilation layer S1 and the ventilation layer S3, and the warm air in the ventilation layer S2 can be exchanged with the ventilation layer S1. By moving to S3, warm air can be easily discharged.

Further, the warm air of the ventilation layer S2 is moved to the ventilation layer S8 via the ventilation layers S3 to S7, and the ventilation provided on the wall surface (not shown) on the left side of the paper surface in FIG. 5 via the ventilation layer S1. It can be moved to a layer (not shown). Further, the air of the ventilation layer S8 provided on the wall surface on the right side of the paper surface in FIG. 5 is passed through the ventilation layers S9 to S11 to the ventilation layer (not shown) provided on the wall surface (not shown) on the back side of the paper surface in FIG. It can be moved to). In this way, air can flow throughout the building.

The positions and numbers of the joiner 1 and the ventilation layer S in FIG. 5 are not limited to the illustrated form. The same effect can be obtained regardless of the position and number of the joiner 1 and the ventilation layer S.

According to the present embodiment, by providing a hole 14 in the side surface 11 of the joiner 1 provided so that the longitudinal direction is substantially along the vertical direction, ventilation can be performed between the inside and the outside of the joiner 1. Further, a ventilation layer S can be provided between the inside of the outer wall material 21 and the base material 23, and ventilation can be performed between the inside of the joiner 1 and the ventilation layer S.

In the present embodiment, the shape of the hole 14 is a round hole, but the shape, position, and number of the holes 14 are not limited to the illustrated form. FIG. 6A is a perspective view showing an outline of the joiner 1A according to the modified example, and FIG. 6B is a perspective view showing an outline of the joiner 1B according to the modified example. Like the joiner 1A, a plurality of long holes 14A may be provided. By providing a plurality of holes 14 and 14A, the air permeability can be improved. Further, like the joiner 1B, one hole 14B which is a long hole may be provided.

Further, when viewed along the y direction, the positions of the holes 14 and 14A provided on the wall surface on the −y side and the positions of the holes 14 and 14A provided on the + y side may be the same. , It does not have to match.

Further, in the present embodiment, the holes 14 are provided on both sides of the pair of side surfaces 11, but the holes 14 may be provided only on one side surface 11. In particular, when a large hole 14B such as the joiner 1B is provided, the hole 14B may be provided only on one side surface 11 in order to maintain the strength of the joiner 1B. In this case, by forming a joint structure of the outer wall material in which the joiners 1B are provided so that the directions of the holes 14B are alternated, ventilation can be performed between the adjacent ventilation layers.

Further, in the present embodiment, the base material 23 is provided with a moisture permeable waterproof sheet on the outer surface (+ x side surface) of the heat insulating material or the studs, but the form of the base material is not limited to this. For example, a heat insulating material or a material in which a moisture-permeable waterproof sheet is provided on the outer surface (+ x side surface) of the stud and a bar material is provided substantially along the vertical direction on the heat insulating material (+ x side) may be used as the base material. Further, a rod material may be provided as a base material on the existing outer wall substantially along the vertical direction. In this case, the joiner 1 and the spacer 22 may be fixed on the bar.

Further, in the present embodiment, since the base material 23 is provided substantially along the vertical direction, the joiner 1 is provided substantially along the vertical direction, but the base material 23 is provided at an angle with respect to the vertical direction. It may have been. In this case, the joiner 1 is also provided with the base material 23 tilted with respect to the vertical direction. That is, the joiner 1 may be provided at the joint portion of the two outer wall materials arranged side by side in the longitudinal direction substantially along the longitudinal direction. Here, the vertical direction is a direction substantially orthogonal to the left-right direction (horizontal direction).

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment and includes design changes and the like within a range not deviating from the gist of the present invention. .. Further, it is possible to adopt a configuration in which the configurations described as the above-described embodiments and modifications are appropriately combined.

Further, in the present invention, the "abbreviation" is a concept including not only a case where the identity is exactly the same but also an error or a deformation to the extent that the identity is not lost. Further, in the present invention, the "neighborhood" is a concept indicating that, for example, when it is in the vicinity of A, it is near A and may or may not include A.
