DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Among buildings, special buildings mainly used by an unspecified number of people are required to have a certain level of fire protection and fire-resistant structure. There is a demand for a partition structure with a base. The present invention relates to an improvement in a partition structure using a steel base.

[0002]

2. Description of the Related Art A base material having a partition structure with a steel base is specified in Japanese Industrial Standard JISA6517-1985. This partition structure with a steel base has a plurality of studs 3, which are pillar members formed by bending a thin plate in a substantially C shape between runners 1 and 2 fixed to the ceiling surface and the floor surface, at regular intervals. Then, a wall material is stuck on the surface to form a partition wall of a fireproof structure. A spacer is mounted on the open side surface of each stud (in the direction of the wall inside the wall structure), and a horizontal steady rest is arranged between the studs. That is, the horizontal steady rest is disposed only inside the thickness of the vertical stud member to form a steel base.

[0003]

A conventional partition structure using a steel base is a non-bearing wall intended only for partitioning a large space, and the base is composed of only a vertical stud and a horizontal steady rest. However, it could not withstand a large force, especially an oblique force due to an earthquake or the like. Therefore, the fact is that it does not provide strong reinforcement in the event of an earthquake or the like.

[0004] To increase the strength, it is conceivable to provide a brace inside the thickness of the stud in the same manner as the steady rest, but this cannot be practically performed. Although it is conceivable to simply fix the brace on the outer surface of the stud, simply fixing the brace in the oblique direction to the outer surface of the stud causes a drawback that laying of the wall material is difficult due to this protruding dimension. . In view of such a situation, an object of the present invention is to provide a partition wall structure which is a fire-resistant structure while providing an earthquake-resistant wall having a certain strength against an earthquake or the like. Still another object of the present invention is to provide a wall structure that can be constructed relatively easily and with a beautiful finish.

[0005]

In the partition structure using a steel base, a plurality of studs 3 and 3 are erected between a runner 1 on a ceiling surface and a runner 2 on a floor surface, and each of the studs is held in a horizontal direction. 4 and 4 are penetrated, and a wall material having fire resistance is attached to the side surfaces of the studs 3 and 3. In the present invention, a brace member 5 having a height H smaller than the thickness T of the lower wall member 6 and having a U-shaped cross section is fixed diagonally to the outer surface of the stud 3, and above and below the brace member 5, respectively. Brace member 5
And the lower wall material 6 is adhered to the outer surface of the stud 3. Then, the space between the lower wall members 6 and 6 sandwiching the brace member 5 having a U-shaped cross section is filled with another wall material so as to have the same height as the lower wall member 6 so that the surface is as flush as possible. Then, the upper wall material 7 is attached to the entire outer surface.

A light gauge 8, which is a thick pillar, is disposed between the studs 3 and 3. The stud 3 and the brace member 5 are fixed with screws, and the light gauge 8 and the brace member 5 are fixed.
When the lower wall member 6 and the bracing member 5 are welded at a portion where they do not come into contact with each other, the overall strength is improved.

[0007]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Runner 1 on the ceiling
And the runner 2 on the floor are both formed by bending a thin plate as a substantially U-shaped gutter having a width equal to the width of the stud 3.

Studs 3, 3, which are pillars formed by bending a thin plate in a substantially C shape, are arranged at regular intervals between the runner 1 and the runner 2, and the studs 3, 3 are penetrated in the horizontal direction to prevent the steady rest 4. , 4 are provided. At the open end of the stud 3, which is a pillar formed by bending a thin plate into a substantially C shape, a spacer 1 is provided at an interval within a certain dimension.
2 and 12 are attached to keep the form as a pillar material.

On the outer surfaces of the studs 3, 3, a brace member 5 is fixed diagonally. The brace members 5 are arranged in different directions on one side surface and the other side surface (see FIG. 1), so that the two cross each other.
And the stud 3 are fixed with screws, for example. Brace member 5
Is a U-shape having a relatively short height H and a height H smaller than at least the thickness T of the lower wall member 6 as shown in FIG.

On the side of the stud to which the bracing member 5 is fixed, a lower wall material 6 which is a fire-resistant wall material is first placed on the side of the stud 3 so as to be brought into contact with the side surface of the bracing member 5 and to be sandwiched from both upper and lower sides. Paste on the side. Inside the brace member 5 having a U-shaped cross section, narrow filling plates 9 and 10 are adhered,
In addition, the flowable filler 11 is applied to the remaining gaps so that the surface height thereof is flush with the lower wall material 6, and the upper wall material 7, which is a fire-resistant wall material, is attached to the entire surface to complete the construction. .

As the steel base, studs 3 and 3 are arranged at regular intervals. In the embodiment shown in FIGS. 1 and 3, a stud for forming a thin plate and a light gauge 8 as a thick plate are used. Are arranged alternately. Also, the cross section U
The U-shaped bracing member 5 is also a U-shaped steel with a certain thickness,
The stud 3 and the brace member 5 are fixed with screws at the bottom surface of the brace member, and the light gauge 8 and the brace member 5 are fixed by welding a contact portion between the back surface of the light gauge 8 and the vertical side edge of the light gauge 8. . This results in an extremely strong steel substrate as a whole.

According to the first aspect of the present invention, according to the seismic partition structure using a steel base, the conventional steel base partition structure intended only for the partition is provided with not only fire resistance but also extremely large seismic strength. Things. In addition, it is difficult to construct the wall only by the idea of simply arranging the brace on the side of the stud. However, in the present invention, the brace member is made substantially U-shaped and the strength is large, and the inside of the brace member is formed inside. In this structure, the filling material is applied, and the surface of the lower wall material and the upper surface of the bracing member are flush with each other. Therefore, although the bracing member is structurally built in, the wall structure is substantially uniform as a whole, and there is an effect that the construction can be easily performed without affecting the fire resistance, the soundproofing, and the heat insulation effect. .

According to the second aspect of the present invention, by arranging the light gauge having high strength in the vertical direction, it is possible to form a partition structure having higher strength as a whole and to function as a bearing wall. .
