Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting an outer wall material for a house, and more particularly to a structure for mounting an outer wall material in which the back surface of the outer wall material has improved air permeability.

[0002]

2. Description of the Related Art As shown in FIGS. 4 to 7, in an outer wall portion of a building, studs 2 are provided at predetermined intervals between pillars 1 which are frames. Each pillar 1
On the outside of the stud 2 and the stud 2, a plurality of base materials (horizontal furring strips) 14, 14, ... Are provided in parallel in the horizontal direction (FIGS. 5 and 7). A plurality of base materials (vertical furring strips) 13, 13, ... Are provided in parallel with each other (FIGS. 4 and 6).

Base materials 14, 14, ... (or 13, 1)
Outside wall material (siding material) 5, 5, ...
Is installed and outer wall work is being done. In addition, the pillar 1, the stud 2, and the base materials 14, 14, ... (Or 13, 13, ...)
In many cases, the waterproof sheet 6 is provided between the sheet and the sheet.

Further, in order to keep the inside of the building thermally shielded from the outside by keeping the air conditioning conditions (temperature and humidity) in the room optimal, the frame 1
A heat insulating material is often provided between the outer wall member 5 and the outer wall member 5.

In such a residential building, in order to prevent the heat insulating material from absorbing moisture, prevent dew condensation due to the temperature difference between the inside and the outside, and improve the drainage property to prevent the heat insulating material and the wood from deteriorating. In recent years, a housing structure by a ventilation method has been used in which a ventilation space 7 is provided between the base material 14 (or 13) and the outer wall material 5 to allow air to flow.

In such an outer wall structure of a building, it is necessary to sufficiently circulate air in the ventilation space 7 between the outer wall material 5 and the base material 14 (or 13). Further, when rainwater enters the ventilation space 7 through a gap between the outer wall members 5 or the like, it is necessary to promptly discharge the rainwater to the outside.

[0007]

However, it is often difficult to circulate air sufficiently with the conventional base material (furnace) structure, particularly the lateral furring structure 14, and the outer wall material 5 is used.
In many cases, the rainwater that has entered the ventilation space 7 from the gaps between them is difficult to discharge, and it is difficult to take advantage of the ventilation method.

That is, in FIG. 5, another horizontal furring strip 14 is arranged on an extension of the longitudinal end 14a of the lateral furring strip 14. Then, the longitudinal direction end portion 14a of the lateral furring strip 14,
14a is a seam 14b which is a gap with an interval of 30 mm.
Are separated by.

By providing such a joint 14b, it is possible to ensure communication between the ventilation spaces 7, 7 which are vertically separated from each other, and the rainwater which has penetrated into the upper ventilation space 7 is connected to the seam 1
After passing through 4b, it falls into the lower ventilation space 7 and is finally discharged from the lowermost ventilation space 7 to the outside.

However, since the horizontal furring strips 14 are arranged substantially horizontally, it is difficult for rainwater to drop into the ventilation space 7 below through the joints 14b. Further, the seams 14b at intervals of 30 mm are insufficient for achieving convection in the vertical direction, and it is difficult to take advantage of the ventilation method (convection in the vertical direction is more effective than in the lateral direction in the ventilation method).

On the other hand, if the seam 14b is enlarged, the function as the lateral furring strip 14 becomes insufficient, and there is also a problem that such a construction is troublesome.

Among the conventional base material (furnace) constructions, the construction of the vertical furring strip 13 is superior to the construction of the horizontal furring strip 14 in terms of ventilation convection and drainage, but the vertically long outer wall material 5 is used. In the case of construction, there is a problem in that the construction needs to be devised unless the space between the pillar 1 and the stud 2 and the plate width of the outer wall material 5 match.

[0016]

1 is a perspective view of an outer wall member mounting structure according to a first embodiment of the present invention. In the outer wall portion of the building, studs 2 are provided at predetermined intervals between the pillars 1 which are the skeletons. On the outside of each pillar 1 and stud 2,
A waterproof sheet 6 is laid so as to cover substantially the entire outer wall portion, and a plurality of base materials (oblique furring strips) 3, 3, ...
Are provided in parallel at predetermined intervals. Base material 3
Is a long member having a rectangular cross section.

The base material 3 is arranged such that the longitudinal direction of the base material 3 is inclined at an angle θ with respect to the horizontal. The base material 3 is generally fixed by nails. That is, nails are driven from the outside of the base material 3, penetrate the waterproof sheet 6, and are fixed to the pillar 1 or the stud 2.

Angle θ of base material 3 with respect to the horizontal direction in the longitudinal direction
Is preferably 15 to 75 degrees, and more preferably 25 to 65 degrees. When the angle θ is less than 15 degrees, it is not easy to discharge the invading rainwater, and when the angle θ is more than 75 degrees, when the vertically long outer wall material 5 is constructed, the pillar 1 and the stud 2 are separated. This is because the space and the plate width of the outer wall member 5 do not match, which causes a difficulty in construction and is not preferable. In FIG. 1, θ is set to about 40 degrees.

In this embodiment, the longitudinal end portions 3a of the base materials 3 are arranged so that the positions of the base materials 3 adjacent to each other are different from each other. Then, another base material 3 is disposed on the extension line of the longitudinal end portion 3a of the base material 3. The longitudinal ends 3a, 3a of the base material 3 are separated from each other by a seam 3b which is a gap of a predetermined distance. By the joint 3b, vertical ventilation of the outer wall members 5, 5, ...

Outside wall materials 5, 5, on the outside of the base materials 3, 3 ,.
... is installed and the outer wall construction is completed. The outer wall material 5 is fixed to the base material 3 by a nail, that is, the nail is fixed to the outer wall material 5.
The method may be one in which the outer wall material 5 is driven in from the outside of the base material or is fixed to the base material 3, or a dedicated mounting metal fitting is fixed to the base material 3 (by nailing or the like) and the outer wall material 5 is locked to the mounting metal fitting. May be.

Further, in the mounting structure of the outer wall material according to the present invention, even when the outer wall material 5 is arranged vertically (FIG. 1),
It can be applied even when the outer wall material 5 is arranged horizontally.

By adopting the constitution of the present invention, the upper and lower convection of ventilation can be achieved and the advantages of the ventilation method can be obtained, as in the constitution adopting the vertical furring strip. Further, in the configuration of the present invention, by adopting the base material (oblique furring strip) 3, it is excellent in discharging rainwater that has entered. Further, with the configuration of the present invention, the outer wall material can be easily constructed without being affected by the distance between the pillar 1 and the stud 2.

FIG. 2 is a front view of an outer wall member mounting structure according to a second embodiment of the present invention. In the drawings, the outer wall member 5 is not shown for easy understanding of the configuration of the present invention. This configuration is the same as the configuration of the first embodiment except that the base material (oblique furring strip) 3 is not provided with the joint 3b at the longitudinal end 3a. Therefore, the same or similar members as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, the positions of the longitudinal end portions 3a of the base materials 3 are different between the adjacent base materials 3. By arranging the positions of the longitudinal end portions 3a in this way, the same effect as that of the first embodiment can be obtained.

FIG. 3 is a front view of the outer wall member mounting structure of the third embodiment of the present invention. In the drawings, the outer wall member 5 is not shown for easy understanding of the configuration of the present invention. Further, the same or similar members as those in FIGS. 1 and 2 are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, a conventional example (FIGS. 5 and 7)
Similarly to the above, a horizontal furring strip is used as the base material 4. However, the positions of the end portions 4a in the longitudinal direction of the base material 4 are arranged so as to be different between the adjacent base materials 4. By arranging the position of the longitudinal end portion 4a in this manner, up and down convection of ventilation can be achieved, and an advantage in the ventilation method can be obtained. Similarly, it is also excellent in discharging invading rainwater.

In this structure, the other base material 4 is not disposed on the extension line of the longitudinal end 4a of the base material 4, and the function as the base material (horizontal furring strip) 4 becomes insufficient. Although there are concerns, the vertical distance between the base materials 4, 4, the width of the base material 4, etc.
It can be dealt with by optimizing the configuration.

As described above, the present invention is not limited to the configuration of each embodiment, and various modes can be adopted. In addition, the optimum configuration depending on the size and material of the outer wall material 5, the size and material of the base materials 3 and 4, and the like, for example, the distance between the pillar 1 and the stud 2,
The spacing between the base materials 3, the arrangement of the joints 3b, the width of the joints 3b, and the like can be arbitrarily selected.

[0029]

According to the present invention, the back surface of the outer wall material can be sufficiently ventilated, and the durability of the skeleton and the like can be improved.
In addition, the rainwater that has entered the ventilation space can be easily discharged, which also improves the durability of the skeleton and the like. Further, the outer wall material can be easily constructed without being affected by the distance between the pillar and the stud.
