Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer wall base panel installed on the outdoor side of a building frame.

[0002]

2. Description of the Related Art Recently, homes in which the skeleton of a conventional wooden house is replaced with a steel frame have become popular. FIG. 18 is a perspective view showing an example of a state in which an outer wall base material is attached to a building frame of such a house with a part omitted, FIG. 19 is a perspective view showing the building frame part, and FIG. 20 is a plane cross section of FIG. It is a figure. In addition,
In the following description, the building body side is referred to as the indoor side, and the side to which the outer wall base material is attached is referred to as the outdoor side.

As shown in the figure, a reinforced concrete foundation 2
Between the base 22 (lower beam) made of steel material having an H-shaped cross section and the upper beam 23 also made of steel material having an H-shaped cross section, which are installed on the top of the base 1, at the center of the base 22 and the upper beam 23 in the width direction. ,
Pillars 25a and 25b made of steel having a rectangular cross section whose one side is narrower than the width of the upper surface thereof are provided at a predetermined interval. Then, on the facing surfaces of the adjacent pillars 25a and 25b and on the intermediate portion between the pillars 25a and 25b, a receiving member 30a made of lip channel steel and a stud 30b are provided with one flange flush with the outdoor side of the base 21. The pillars 25a and 25b and the intermediate stud 30b are fixed to the base 21 and the upper beam 23 by bolts via the pillar pedestals 32a and 32b.

33 (see FIG. 19 (a)) is an adjacent pillar 2
5a and 25b are cross-shaped braces that are attached to the upper and lower portions of the 5a and 25b. When the brace 33 is attached, the studs 30b provided in the middle portion interfere with each other. As shown in (b), a through hole 31 for passing the brace 33 is provided.
In addition, the receiving material 30 attached to the opposing surfaces of the pillars 25a and 25b
a is a brace 3 provided on the pillars 25a and 25b at the top and bottom thereof.
Since the mounting metal fittings of 3 interfere, the portion is cut off and the web is fixed to the columns 25a and 25b by tapping screws or the like.

In order to mount the outer wall base material 35 on the building frame as described above, first, the plywood 36 is used as the support material 30a and the studs 3 are used.
0b is brought into contact with the flange on the outdoor side and joined by a tapping screw or the like, and the plate-shaped heat insulating material 37 is joined to the outdoor side. Then, the waterproof sheet 38 is arranged on the outdoor side of the heat insulating material 37, and the ventilation vertical furring strips 39 are installed on the outdoor side in correspondence with the receiving material 30a and the studs 30b. It is fixed to the receiving member 30a and the stud 30b with nails or the like.
Finally, the finishing material 40 such as siding is attached to the outdoor side of the ventilation vertical furring strip 39, and the construction is completed. At this time, a ventilation space 41 is formed between the waterproof sheet 38 and the finishing material 40. Further, when a fibrous heat insulating material is used in place of the heat insulating material 37, a moistureproof layer is arranged between the plywood 36 and the fibrous heat insulating material in order to prevent water vapor from entering the heat insulating material from the room.

Direct heat insulating material 37 without using plywood 36 as a base
Also in the case of configuring by attaching, the construction is performed in the same procedure except for the attachment portion of the plywood 36. In addition, the supporting member 30a is omitted, and the stud 30 made of shaped steel has the same shape as the pillars 25a and 25b.
b, the pillars 25a and 25b, the studs 30b, and the base 22
Also in the case of using the spacers on the outdoor side surfaces of the pillars 25a, 25b and the studs 30b to cope with the difference in width from the flanges, etc.,
The construction is performed by replacing the step of attaching the plywood 36 with the step of attaching the spacer.

[0007]

Conventionally, in the building frame to which the outer wall base material is attached, the flange of the base 22, the flange of the upper beam 23, and the column base metal fitting 32a for fixing the columns 25a and 25b are replaced by the columns 25a and 25b. Since it protrudes from the outdoor surface to the outdoor side, the outer wall base material 35 is directly connected to the pillars 25a and 25b.
When they are attached to the outdoor surface of, the protrusions interfere with each other and they cannot be attached. Therefore, the outer wall base material 3
The portion corresponding to the projecting portion of No. 5 must be subjected to a hanging process or a notch process, which takes a lot of time and labor, resulting in an increase in cost and inevitably a decrease in heat insulation performance.

The plate-shaped heat insulating material 37 of the outer wall base material 35
If a fiber-based heat insulating material is used instead of the base material, it is necessary to construct a base plywood and add a furring strip as an exterior receiving material to maintain the shape. Poor workability due to the need to cut out plywood.
When the base plywood was omitted, it was extremely difficult to apply the moisture-proof layer in this part, and it was practically impossible to use the fiber-based heat insulating material.

In order to solve such a problem, FIG.
As shown in FIGS. 20 to 20, there is also a method in which the receiving member 30a and the studs 30b are provided, and the outdoor surface thereof is equal to or more than the outdoor surface of the base 22, and the outer wall base material 35 is attached to this outdoor surface. In this case, the number of parts becomes very large and the weight of the member increases, which is disadvantageous in terms of workability and cost. Further, a method of inserting a spacer such as a plywood thicker than the protruding portion on the outdoor side of the stud 30b is also implemented, but in this case as well, the number of parts and construction labor increase, which is disadvantageous in terms of cost.

Further, since the through hole 31 for passing the brace 33 must be provided in the stud 30b, more labor and cost are required, and the work of installing the brace 33 through the through hole 31 is also troublesome. , Improvement is required. Further, in the case where the waterproof sheet 38 is an airtight sheet in order to make it an airtight house, the treatment of the joint is troublesome, and if it is not securely constructed, the airtightness is deteriorated and moisture enters the inside. It may also lead to building durability problems, such as impairing the ventilation effect in the ventilation space. There is also an example in which a part of the outer wall base material is panelized. However, when the waterproof sheet 38 is installed after the panel is attached by simply panelizing the plywood and the heat insulating material, the effect of rationalizing the installation is low, and the waterproof sheet. If 38 is previously attached to the panel as an airtight sheet in advance, there is a problem in that it is difficult to perform airtight processing on the joints.

The present invention has been made to solve the above problems, and can greatly reduce the number of parts such as receiving members, studs, and the like, and can be easily installed and the cost can be reduced. The purpose is to provide a panel.

The uppermost horizontal furring strip 4a and the lowermost horizontal furring strip 4b that make up the above are formed longer than the other horizontal furring strips 4 and are projected outward from both sides of the vertical furring strips 3a and 3b. The protruding length is set to be substantially equal to or slightly longer than the end of the indoor flange 6c of the mounting member 6. Then, on the outdoor side of the panel frame 2, an airtight material 7 (shown by a broken line and a one-dot chain line) having an area larger than the surface area of the panel frame 2 including the upper and lower horizontal furring strips 4a, 4b is attached by a fastener 9. is there.

In this embodiment, the seam 16 formed between the adjacent panel frames 2a and 2b is attached to the pillar 25 of the panel frame 2 and, as shown in FIG. After overlapping 7a on the outdoor side and closing it,
The upper extending piece 7a is overlapped to wrap around the uppermost horizontal furring strip 4a of the panel frames 2a and 2b, and is fixed to the indoor side of the horizontal furring strip 4a by a fastener 9 so that the adjacent panel frames 2a and 2b
The vertical furring strip 11 for ventilation is attached to the vertical furring strips 3a and 3b of b.
In this case, the extending piece 7a of the airtight material 7 of the panel frames 2a, 2b on the upper floor extends to the outdoor surface of the uppermost horizontal furring strip 4a of the panel frames 2a, 2b on the lower floor, and is attached to the lateral furring strip 4a. Secure with fasteners 9.

In each of the above-described embodiments, the case where the vertical furring strips, the horizontal furring strips, the ventilation vertical furring strips, or the like, which constitute the panel frame, are made of wood is shown, but the present invention is not limited to this. Instead of these, the vertical furring strips and the like may be made of a steel material having a rectangular cross section, a U-shape, an L-shape, an H-shape, or the like.

[0049]

The outer wall base panel according to the present invention is provided with a mounting member having a substantially Z-shaped cross section on the indoor side, and the indoor side flange of this mounting member is fixed to a pillar to form a base (lower beam) or upper beam. Since the step formed between the pillar and the pillar is absorbed by the web of this mounting member, it is not necessary to carry out chipping or the like to avoid interference of the step when mounting the outer wall base member, and therefore It is possible to prevent the deterioration of the heat insulation performance by improving the property.

Further, since it is possible to omit the receiving material, the studs, the pillar pedestal for fixing these to the base (lower beam), the spacer, etc., which have been conventionally required, it is possible to greatly reduce the number of members and to carry out the construction. Therefore, the cost can be reduced. Further, by forming the airtight material to be installed on the outdoor side of the panel of the outer wall base larger than the panel frame, the seam formed between the adjacent outer wall base panels at the time of installation can be joined by overlapping the airtight material. Therefore, airtightness and waterproofness can be further improved.
