The panel main body 1 is a rectangular plate-like body such as structural plywood, particle board, oriented strand board (OSB), hard board, hard wood cement board, gypsum board, sizing board, volcanic glass laminate, lath sheet, etc. In addition, materials that are recognized as face bearing walls in Article 38 of the Building Standards Act can be adopted. On the other hand, the waist edges 2, 3 have a width of 30-50mm, a thickness of 10-30mm, and the length is the same as or slightly shorter than the length of the panel main body 1. The width of the above-mentioned nail-attached portions 5 and 5 formed between both end surfaces of the panel main body 1 is a width that can be nailed by an automatic nailer, in the embodiment, is approximately 22 mm, but it is 10 mm depending on the automatic nailer width. Is selected arbitrarily between 30mm and 30mm. Moreover, the outer side end surfaces of the two side waist materials 2, 2 are formed on the flat guide side surface 6 over the entire length where the nozzle N (shown in FIG. 4) of the automatic nailer is slidably contacted.
[0016]
7 is a heat insulating material fixed to the back side of the panel main body 1, which is formed in a vertically long rectangular shape having a constant thickness that is slightly smaller than the panel main body 1, and its four-sided outer peripheral surface is constant from the four-side outer peripheral edge of the panel main body 1. The upper and lower edges 1a, 1b and both side edges 1c, 1c on the back surface of the panel main body 1 are made of the heat insulating material 7. It is exposed from the upper and lower end surfaces and both end surfaces.
[0017]
The heat insulating material 7 is made of heat insulating material such as glass wool, insulation board, polystyrene foam, rock wool, urethane foam, etc., and the thickness thereof is the same as that of the vertical axis member 21 and the horizontal member 22 which are structural shaft members of the building shown in FIG. It is formed to have a constant thickness equal to or thinner than the thickness (thickness), and the horizontal width is between the opposing surfaces of the adjacent studs or the pillars and the studs, or between the facing surfaces of the neighboring studs and the studs, which are the vertical axis members 21. In addition, the vertical width is the dimension between the base which is the horizontal member 22 and the opposite surface of the trunk difference, or between the opposite of the trunk difference and other horizontal members such as girders and floor beams. Are formed substantially equal to each other. That is, the rectangular frame-shaped space surrounded by the left and right vertical axis members 21 and 21 and the upper and lower horizontal members 22 and 22 is formed in substantially the same size and shape. Note that the heat insulating material 7 may be formed larger than the space portion and cut so as to have a size that can be fitted into the space portion during construction.
[0018]
Further, as shown in FIG. 2, the crosspiece 8 is fixed to the center of the back surface of the panel main body 1 over the entire length of the heat insulating material 2 so as to divide the heat insulating material 7 into left and right parts. As shown in the figure, the thickness (thickness) of the crosspiece 8 is substantially equal to or slightly thinner than the thickness of the heat insulating material 7. Two or more crosspieces 8 may be provided, or a crosspiece perpendicular to the crosspiece 8 may be provided.

This nail driving 9 is performed using an automatic nailing machine, and since the width of the upper and lower ends of the panel main body 1 is short, the surface side of the panel main body at regular intervals on a substantially horizontal line as a guide. The upper and lower horizontal members 22, 22 with which the upper and lower ends are in contact with each other can be nailed.
[0020]
On the other hand, since the lengths of both side ends of the panel main body 1 are long, if the nailing operation is performed according to a guideline, the nailing intervals may be uneven or the nailing may occur in a state shifted in the left-right direction. For this reason, as described above, the two side edge members 2, 2 are fixed to the inner positions at regular intervals from the both side edges of the panel main body 1, and the both side ends of the panel main body 1 outside these body edge materials 2 are fixed. The part is formed in the to-be-nailed portions 5 and 5. Then, as shown in FIG. 4, the nozzle N of the automatic nailer is applied to the guide side surface 6 formed on the outer end surface of the body edge material 2 and is in sliding contact with the guide side surface 6. While the automatic nailer is moved in the length direction of the material 2, the to-be-nailed portion 5 is nailed to the vertical axis material 21 at regular intervals.
[0021]
Thus, when the nailing operation is performed by the automatic nailer using the guide side surface 6 of the barrel edge material 2 as a guide, the nailing operation can be performed sequentially in a straight line in a direction parallel to the barrel edge material 2. In addition, the nail driving interval can be provided at almost constant intervals as a guide, but as shown in FIG. For example, the nailing 9 can be performed on the nailed portions 4 and 4 at both ends of the panel main body 1 at a certain length interval more accurately and efficiently.
[0022]
After fixing the wall panel to the structural shaft material of the building in this way, as shown in FIG. 3, while attaching the horizontally long rectangular siding material (outer wall plate) 11 to the surface side of the wall panel, the upper and lower opposing end surfaces are joined together. The exterior wall is constructed by sequentially stretching. The siding material 11 is constructed by stretching the siding material 11 on the body edge materials 2 and 3 attached to the surface of the panel main body 1 in a erected state, and nailing from the surface of the siding material 11 to the body edge materials 2 and 3. It is fixed through hammering or screwing or metal fittings.
[0023]
As described above, when the siding material 11 is fixed to the surface of the wall panel, the surface side of the space portion 4 between the adjacent trunk edge materials 2 and 3 of the panel main body 1 is closed by the siding material 11, and the space portion 4 becomes the panel main body. 1 is formed in the ventilation space 4 'penetrating in the vertical direction of 1, and the outside air circulates through the ventilation space 4' to release radiant heat from the wall structure and prevent the columns 21 and the intermediary columns from decaying. Can do. In addition, as shown in FIG. 3, a waterproof joint tape 15 is attached to the surface between the nail-bonding portions 5 and 5 of the adjacent panel main bodies 1 and 1 joined in abutting state with each other. The rainwater or the like is prevented from entering the inside through the gap between the opposite end surfaces.
[0024]
FIGS. 5 and 6 show another embodiment of the wall panel of the present invention, and the trunk edge adjacent to the two side waist materials 2 and 2 and the intermediate waist material 3 fixed to the surface of the panel main body 1. A passage 12 communicating with the space 4 between the materials 2 and 3 is formed at predetermined intervals in the length direction. Other structures are the same as those of the wall panel. When the panel main body 1 is provided with an opening 13 such as a window, the passage 12 is provided in the trunk edge members 2 and 3 positioned around the rectangular frame 14 fixed to the peripheral edge on the surface side of the opening 13. In other words, it is provided on the body edge members 2 and 3 that abut against the upper and lower frame parts 14a and 14b of the rectangular frame 14, and on the body edge members 2 and 3 along the left and right frame parts 14c and 14c of the rectangular frame 14, respectively.
[0025]
In this way, when the passage 12 is provided in the body edges 2 and 3, the siding material 11 is stretched on the surface of the panel main body 1, and the siding material 11 is fixed to the body edges 2 and 3. When the surface side opening end of the space portion 4 between the body edges 2 and 3 to be closed is closed to make the space portion 4 a ventilation space portion 4 ′, the flow of air flowing through the ventilation space portion 4 ′ is rectangular. Without being blocked by the frame 14, it can flow through the passage 12 to the adjacent ventilation space 4 ′ along the rectangular frame 14, and can smoothly circulate air in the length direction of the panel main body 1. It is.
[0026]
As a form in which the passage 12 is provided, in FIG. 5, short trunk edges 2 ′ and 3 ′ obtained by dividing the trunk edges 2 and 3 at predetermined intervals in the length direction are long on the surface of the panel main body 1. It is formed by the small interval portions by being fixed at small intervals in the direction, but as shown in FIG. 7, it is V-shaped at predetermined intervals in the length direction on the body edge materials 2 and 3.
