JPH0765357B2 - New medium space partition wall and its assembly method - Google Patents

Description

The present invention relates to a novel medium space partition wall and a method for assembling the same.

[Conventional technology]

In recent years, the number of high-rise steel-framed buildings has increased, and the development of fireproof partition wall construction methods required by the Building Standards Act has become active.

As a fireproof partition wall, a medium space partition wall with a gypsum board on both sides of a light steel frame is easy to wire and pipe in the hollow part and is hidden inside the wall, which has the advantage of good aesthetics and high sound insulation. In this case, the gypsum board is usually attached to the stud with tapping screws from both sides of a lightweight steel frame base using studs of light-mezo steel or lip-mizo type steel.

[Problems to be solved by the invention]

However, when assembling around cores such as around stairs and elevators, it is difficult to assemble scaffolds on the opening side (outside of the room) of the lightweight steel frame base, and it is extremely dangerous even if it can be compared. It is a work involved,
The actual situation is that the partition wall for the middle space is not assembled.
Therefore, at present, thick bricks, thick concrete blocks, ALC boards, etc. that can be assembled only from the indoor side are used. However, the material becomes heavier, there is no hollow part, so wiring and piping are troublesome, and wiring on the wall surface,
Since the piping is exposed, it has a drawback that the appearance is impaired and the sound insulation is inferior.

Further, when a conventional medium space partition wall is used as a wall between adjacent doors of a hotel, an apartment, etc., there is a psychological anxiety regarding crime prevention in that the plaster board can be easily destroyed by a knife or a hammer.

Under such circumstances, a new method of assembling the mid-space partition wall around the stairs and around the core around the elevator has been desired. Also, due to the recent increase in crime, it has been earnestly desired to develop an intermediate partition wall that eliminates psychological anxiety regarding crime prevention.

It is an object of the present invention to provide a new medium space partition wall and a method for assembling the same, which solves the above problems.

[Means for solving problems]

That is, the present invention is (1) in a medium space partition wall in which panels are installed opposite to each other on both sides of a lightweight steel frame base, the lightweight steel frame base is formed of studs of Z type steel or lip Z type steel, and at least the panel One is a gypsum sandwich panel in which a metal plate is sandwiched and fixed by two gypsum boards, and these panels are attached to a lightweight steel frame substrate from the same direction by a mounting member, which is a new hollow. By attaching the panel from one direction to the partition wall and (2) one side of the lightweight steel frame base made of Z-type steel or lip Z-type steel stud with the attaching member, and then attaching the panel to the other side from the same direction with the attaching member. And at least one of the panels is a gypsum sandwich panel in which a metal plate is sandwiched and fixed by two gypsum boards. That is a method of assembling the novel hollow partition wall.

A gypsum board is typical as the panel of the present invention,
At least one of the panels should be a gypsum sandwich panel. The gypsum sandwich panel uses metal plates, that is, cold-rolled steel sheets, chemical conversion treated steel sheets, mild steel sheets, organic coated steel sheets, etc. as the core material to sandwich the gypsum board in order to increase the holding power of the tapping screws, etc. is there. The thickness of the metal plate may be determined depending on the application, but usually 0.1 to 2
It is about mm. The thickness of gypsum board is usually about 10 to 30 mm. The metal plate and the gypsum board are generally fixed by an adhesive.

A Z-type steel or lip Z-type steel stud is used as the lightweight steel frame base.

The mounting member is a member for mounting the gypsum board on the lightweight steel frame substrate, and includes tapping screws, metal screws, nails, etc. Among them, the tapping screws are preferable.

[Action]

 Hereinafter, description will be given with reference to the drawings.

FIG. 7 is a vertical sectional view of a conventional medium space partition wall. 7th
As is clear from the figure, the facing gypsum boards 8 are attached to the lightweight steel frame base 4 by the tapping screws 7 from the opposite directions. Therefore, when assembling such a medium space partition wall, the assembly work must be done from both sides of the lightweight steel-frame base 4, and it is impossible to assemble around the core. If the gypsum is attached from the same direction with a tapping screw, the strength of the gypsum itself is extremely weak, and therefore it is impossible to fix the gypsum board on at least one side to the lightweight steel frame base.

FIG. 1 is a perspective view of a gypsum board sandwich panel used in the present invention, FIG. 2 is a sectional view taken along the line AA ′, and FIG. 3 is a view of an assembling process when assembling the intermediate space partition wall of the present invention around an elevator box. FIG. 4 shows a step, FIG. 4 is a sectional view taken along line BB ′, FIG. 5 is a partially cutaway enlarged view of portion C in FIG. 3, and FIG. 6 is a horizontal sectional view of the intermediate space partition wall of the present invention. Is. As is clear from these figures, the gypsum board sandwich panel 3 holds the metal plate 1 by the gypsum board 2, so that the lightweight steel frame base 4 can be easily attached to the lightweight steel frame base 4 by a mounting member 7 such as a tapping screw regardless of the mounting direction. It can be attached securely and securely.

In order to assemble the medium space partition wall of the present invention, as shown in FIGS. 3 and 4, first, the lightweight steel frame base 4 is assembled with the runner 5 and the stud 6 of the lip Z type steel, and the gypsum sandwich panel 3 is attached to the lightweight steel frame. The base 4 is applied to the surface 4a on the elevator box side (outside the room), and fixed from the indoor side to the lightweight steel base 4 with a tapping screw 7. Next, as shown in FIG. 6, the plaster board 8a is fixed to the indoor surface 4b with the tapping screw 7, and the second plaster board with the tacker pin 9.
Overlap 8b. Of course, the interior panel may be a plaster sandwich panel.

In the present invention, Z-type steel or lip Z-type steel is used instead of the conventional light groove steel or lip grooved steel sheet for facilitating fixing of the gypsum sandwich panel to the lightweight steel frame substrate. The gypsum board sandwich panel is used on at least one side because it is necessary to increase the holding force of a mounting member such as a tapping screw when a scaffolding for work cannot be assembled and the opposite side is fixed to a light steel frame.

〔The invention's effect〕

According to the method for assembling a medium space partition wall of the present invention, since the medium space partition wall can be assembled only from one side, the medium space partition wall around the core such as around stairs and elevators that could not be done by the conventional assembly method. It is possible for the first time to easily assemble. Further, when it is adopted as a partition wall for a space in a hotel or an apartment, it is possible to eliminate the psychological anxiety regarding crime prevention with respect to the wall between adjacent doors, which was a problem with the conventional gypsum board wall surface. Further, in the medium space partition wall of the present invention, it is not necessary to penetrate a mounting member such as a tapping screw through the gypsum sandwich panel, and therefore, in the event of a fire, heat can be transferred from one surface of the partition wall to the other surface through the mounting member. Also, the fire resistance is improved. Of course, wiring and piping can be easily passed through the hollow part of the intermediate space partition wall, which shortens the construction period.
