It shall be.
[0024]
According to FIG. 4, first, a wall panel 4 having a height dimension of H ₁ is erected on the foundation 2. Here, the wall panel 4 is a structural panel in which the foam heat insulating material 12 is a core material and two structural surface materials 4a are integrated on both surfaces of the foam heat insulating material 12 by adhesion. And the upper end part of this wall panel 4 has the upper end surface of the foam heat insulating material 12 located inside from the upper end surface of the two structural surface materials 4a, and the concave connection part 4d is formed.
[0025]
Next, the lower chord frame member 14 b side of the structural beam panel 10 is connected to the upper portion of the wall panel 4. In that case, the convex connection part 20 formed in the lower end part of the structural beam panel 10 is inserted into the concave connection part 4 d of the wall panel 4. And although not shown in figure, the convex connection part 20 and the concave connection part 4d are nailed.
[0026]
Next, the edge of the upper floor slab (upper floor member) 6 is placed on the upper chord frame member 14a of the structural beam panel 10 and secured with nails. Then, a wall panel is erected on the edge of the upper floor slab 6 to form the upper floor. The wall panel 8 has the same structure as the above-described lower wall panel 4. Then, the roof panel 9 is fixed to the upper end portion of the wall panel 8.
[0027]
4 is a ceiling plate connected to the lower surface side of the upper floor slab 6 via a beam member 23. Here, in this embodiment, the edge part of the ceiling board 24 is contact | abutted to the lower chord frame material 14b of the structural beam panel 10 using the elongate beam member 23. FIG. Thereby, the beam member 23, the upper floor slab 6, and the ceiling board 24 suppress buckling of the structural beam panel 10.
[0028]
According to the wall assembling method described above, the structural beam panel 10 is connected to the upper end portion of the wall panel 4 forming the lower floor, so that the wall height of the lower floor is equal to the height dimension H ₁ of the wall panel 4. To the height dimension H ₂ of the structural beam panel 10. Then, since the arranged edge of the upper floor slab 6 on the upper end portion of the structural beam panel 10, the ceiling height h ₂ of the lower floor from the lower floor of the floor to the ceiling plate 24 is sufficiently high It becomes a dimension. That is, the ceiling height h ₂ is higher than the ceiling height h ₁ of the conventional structure shown in FIG.
[0029]
Accordingly, the ceiling height in the room can be increased only by connecting the structural beam panel 10 to the upper portion of the wall panel 4 without setting the height dimension H ₁ of the wall panel 4 to be long. Can answer the demands of housing construction. Further, when the structural beam panel 10 disposed between the wall panels 4 and 8 is a decorative beam, it is possible to improve the aesthetic appearance and make a wall excellent in design.

And since the foam insulation 12 is excellent in heat insulation and sound insulation, there is no need for special work such as attaching heat insulation or sound insulation around the beam, and heat insulation and sound insulation performance while reducing construction costs. An excellent wall structure can be obtained.
[0033]
Further, since the convex connection portion 20 is formed at the lower end portion of the structural beam panel 10 and the concave connection portion 22 is formed at the side portion, the connection to the wall panel 4 and other structural beam panels 19 is achieved. Work can be done easily.
[0034]
Furthermore, the rectangular frame body 14 of the structural beam panel 10 uses a square member W having a rectangular cross section in which the long side dimension L is set to be approximately twice the short side dimension S. It is formed by changing the direction of the short side or by framing the square W in a state of being overlapped. Further, the convex connection portion 20 formed at the lower end portion of the structural beam panel 10 is also formed by projecting the double stacked square members W further outward than the two structural face materials 16. Thus, when the structural beam panel 10 is formed, the number of parts can be reduced by using the same standard product (square bar), so that the unit price of the structural beam panel 10 can be reduced.

The structural beam panel according to the present invention is not limited to the structure of the structural beam panel 10 shown in FIGS. 1 to 3, and the same effect is obtained even if the width dimension and the height dimension are different from the above-described figures. An effect can be obtained. Further, in the structural beam panel 10 of FIGS. 1 to 3, the convex connection portion 20 is formed at the lower end portion and the concave connection portion 22 is formed at the side end face, but this is limited to the formation position. is not.
[0036]
【The invention's effect】
As described above, according to the wall assembling method of the first aspect of the present invention, the structural beam panel is connected to the upper end portion of the structural wall panel forming the lower floor. This is the dimension obtained by adding the height dimension of the structural beam panel to the height dimension of the structural wall panel. And since the edge part of the floor member for upper floors is arrange | positioned at the upper end part of the structural beam panel, the height from the floor of a lower floor to a ceiling becomes a sufficiently high dimension. As a result, the ceiling height in the room can be increased simply by connecting the structural beam panel to the upper part of the structural wall panel without setting the height dimension of the structural wall panel long. Can answer the demands of housing construction.
[0037]
In addition, the structural wall panels used are of a height that can be transported by ordinary vehicles, and the structural beam panels are also members with a short height, so they can be transported to the construction site without using a special transport vehicle. can do. Therefore, the material transportation cost does not increase, so that the construction cost can be reduced.

Furthermore, when the structural beam panel disposed between the structural wall panel on the lower floor and the structural wall panel on the upper floor is used as a decorative beam, it is possible to improve the aesthetic appearance and make the wall excellent in design.
[0039]
According to the structural beam panel of claim 2, the structural beam panel is provided with a rectangular frame so as to surround the outer periphery of the foam heat insulating material, and on both sides of the rectangular frame and the foam heat insulating material. Since it has a structure in which two structural face materials are integrated, it becomes a structural member that can sufficiently resist horizontal forces such as seismic force and wind pressure and vertical load.
[0040]
And since the foam heat insulating material is excellent in heat insulating properties and soundproofing properties, special work such as sticking of heat insulating materials and soundproofing materials around the beam portion becomes unnecessary. And if a foam heat insulating material is used also for the structural wall panel, the wall structure excellent in the heat insulation performance and the soundproof performance can be obtained while reducing the construction cost.
[0041]
Further, according to the structural beam panel of claim 3, the effect of claim 2 can be obtained, and a concave or convex connection portion is formed on the outer peripheral end surface. Therefore, the connection work can be easily performed.

Furthermore, according to the structural beam panel of claim 4, the effect of claim 3 can be obtained, and when the structural beam panel is formed, the length of the long side and the short side is used as the material of the rectangular frame. Is used, and the number of parts can be reduced by using the same standard. Therefore, the unit price of the structural beam panel can be reduced. In addition, the concave or convex connection portion formed on the outer peripheral end face of the structural beam panel is also changed by changing the direction of the long and short sides of the square bar, It can be formed simply by projecting from the structural face material or by being positioned inside.
