DETAILED DESCRIPTION OF THE INVENTION The present invention will be described below with reference to FIGS. In each drawing, a rectangular frame body 17 used in a steel house, a wall plate 10 made of gypsum board or plywood attached to the side surface of the rectangular frame body 17, and a thin steel plate bonded to the inner side surface of the wall plate 10. Brace face plate 18
It is shown.

To explain further, both the lower horizontal frame member 1 and the vertical frame member 2 forming the rectangular frame 17 have a thickness of 0.6 m.
It is formed by bending one thin steel plate in the range of m to 1.6 mm into a U-shape by roll forming in order to enhance its strength, and forms the web 5 and the flanges 6 at both ends of the web 5. have.

Both side flanges 6 at the lower end of the vertical frame member 2 are put inside the flange 6 rising above the lower horizontal frame member 1,
A hole-down hardware (not shown) is arranged inside the joint between the frame members 1 and 2, and the vertical frame member 2 and the upper and lower horizontal frame members 3, 1 are bonded via the hole-down metal member. Rectangular frame 1
7 is configured.

In the present invention, a brace face plate 18 made of a thin steel plate is used in place of the conventional strip-shaped braces (that is, strip-shaped braces), and accordingly, in the present invention, a strip-shaped brace end portion is used. The gusset provided in the is unnecessary.

The brace face plate 18 is different from the conventional attaching process to the rectangular frame body having a strip-shaped bracing. That is, the brace face plate 18, the gypsum board or the wall plate 10 made of plywood is preliminarily bonded to the entire inner surface with an adhesive, and thus the wall plate 10 and the brace face plate 18 are integrated to form the wall plate body 19. To be done.

In the above, the thickness of the thin steel plate forming the brace face plate 18 is preferably 0.23 mm to 0.6 mm.
The reason is that if it is less than 0.23 mm, the manufacturing cost of the steel sheet is high and it is uneconomical, and if it exceeds 0.6 mm,
This is because the wall becomes thicker and the workability deteriorates.

The type of adhesive used to bond the brace face plate 18 and the wall plate 10 is vinyl acetate type, urethane type, epoxy type, synthetic rubber type, or chloroprene type. Furthermore, the thickness of the adhesive layer is 1 to 500 microns. The reason is that if it is less than 1 micron, an unbonded portion occurs, and if it exceeds 500 microns, it takes time to cure the adhesive, which is not economical.

As described above, the wall plate body 19 in which the brace face plate 18 and the wall plate 10 made of gypsum board or plywood are integrated by the entire surface bonding with the adhesive is the rectangular frame 1
It applies to the side of 7. At this time, the brace face plate 1
8 directly contacts the side surfaces of the vertical frame member 2 and the upper and lower horizontal frame members 3, 1. Subsequently, a drilling tapping screw 22 is driven from the outside of the wall plate 10, and the drilling tapping screw 22 includes the wall member 11, the brace face plate 18, and the vertical frame member 2.
Or, it is driven through the side surfaces of the upper and lower horizontal frame members 3, 1. As a result, the brace face plate 18 and the vertical frame member 2 and the upper and lower horizontal frame members 3, 1 are securely joined to each other in a surface contact state without any gap.

FIGS. 7 to 12 show a concrete structure of a wall member 21 in which a wall plate body 19 in which a brace face plate 18 is entirely bonded to a gypsum board 13 is fixed to a rectangular frame 17. 13 to 18, a wall plate body 1 in which a brace face plate 18 is entirely bonded to a plywood 14 as the wall plate 10 is shown.
The concrete structure of the wall member 21 formed by fixing 9 to the rectangular frame 17 is shown. In these wall members 21, the joint structure of the vertical frame members 2 and the upper and lower horizontal frame members 3, 1 constituting the rectangular frame body 17 and the joint structure of the wall plate body 19 to the rectangular frame body 17 are shown in FIG. 2 is the same as that shown in FIG. 2, and therefore, the same elements as those shown in FIG.

In the structure of the wall material according to the present invention, an in-plane shear proof test was conducted to investigate the resistance to seismic force and wind force. This will be described below.

In the test diagram of FIG. 3, the vertical frame member 2 is joined between the lower horizontal frame member 1 fixed to the foundation 27 and the upper horizontal frame member 3 fixed to the beam 26 to form a rectangular frame. Body 17 is constructed,
Further, the wall material structure according to the present invention is shown in which the wall body 19 in which the brace face plate 18 is adhered to the wall plate 10 of the gypsum board is fixed to the side surface of the rectangular frame body 17 by the drilling tapping screw. . In this wall material structure, a horizontal shear load A acts due to seismic force or wind force, and the rectangular frame 1
7 and the wall body 19 are displaced from the solid line to the dotted line in the figure, and the maximum proof stress and initial rigidity when the beam 26 horizontally moves by the deformation amount L are as shown in FIG. Note that FIG. 4 shows the maximum proof stress and the initial rigidity at the same time when the brace face plate 18 and the gypsum board are not bonded. As the test body, a plaster board having a thickness of 12 mm, a brace face plate having a thin steel plate of 0.23 mm and an adhesive (vinyl acetate-based thickness of 10 μm) were used, and an in-plane test was performed on this.

In this case, the horizontal shear strength ratio of the case where the brace face plate 18 made of a thin steel plate is adhered to the gypsum board and the case where it is not adhered is as shown in FIG. 5, and the horizontal shear strength when adhered is large. I understand. Further, the horizontal shear rigidity ratio at this time is as shown in FIG. 6, and from this figure, the horizontal shear rigidity ratio when the brace face plate 18 and the gypsum board are bonded is significantly larger than that when not bonded. I understand.

From the above, the brace face plate 18 made of a thin steel plate having the structure of the present invention is used as the wall plate 1 made of gypsum board or plywood.
The wall body 19 formed by entirely adhering to the
It was confirmed that the wall material configured by being fixed by using the drilling tapping screw 22 has a high tenacity structure with high resistance to seismic force and wind force.

[0025]

As described above, according to the present invention, the brace face plate made of thin steel plate is preliminarily adhered to the wall plate made of gypsum board or wood plywood with an adhesive to form the wall body. By applying the wall body to the side of the rectangular frame and joining the gypsum board or wood plywood and the thin steel plate that is the brace face plate together to the rectangular frame with the drilling tapping screw, the thin steel plate and the gypsum board or wood There is no protrusion of drilling tapping screw between the plywood, and thus it is possible to prevent deformation and destruction of gypsum board and wood plywood, and the presence of the brace face plate improves the in-plane shear strength of the wall. be able to.

Further, conventionally, the gypsum board had a weak point that it was easily broken at the time of a concentrated load such as a collision, but in the present invention, by bonding a thin steel plate to the back surface of the gypsum board, such breakage occurs. Can be prevented. Furthermore, in the structure in which the steel material can vibrate independently like the conventional structure, vibration and sound transmit the steel material, leading to deterioration of comfortability, whereas in the present invention, the thin steel plate and the gypsum board or the wood plywood are bonded. In this case, vibration and sound are absorbed by the adhesive layer and the gypsum board or wood plywood, which improves the habitability.
