Abstract

PURPOSE: To lessen the wall thickness while the fireproof performance and sound isolating performance at the boundary wall are well maintained. CONSTITUTION: A lower runner 6 and an upper runner 7 are opposingly installed along a boundary wall A, and the top and bottom of an undulate steel plate 9 are attached with tapping screws 10 to flanges 6a, 7a of runners 6, 7. A gypsum board 11 is secured to the steel plate 9 using an initially coned tapping screw. An undulate steel plate of a thickness approx. 1/10 of that of gypsum board can exert a sound isolating performance to the same degree, and further because the steel plate has non-combustibility and fireproofness, the thickness can be lessened while the sound isolating performance and fireproofness of the boundary wall can be well maintained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barrier wall structure capable of maintaining fireproof performance and sound insulation performance and reducing the thickness.

[0002]

2. Description of the Related Art Boundary walls, unlike other partition walls, are required to have high fireproof performance and sound insulation performance. An ordinary boundary wall is generally constructed by laminating a gypsum board on a base formed by combining wood and steel materials in a grid pattern. In particular, in the case of a steel structure wall, two gypsum boards are laminated to pass the 1-hour fire resistance standard set by the Minister of Construction, and more than the general partition wall in order to exert sufficient sound insulation performance. It is necessary to increase the wall thickness.

[0003]

In the above boundary wall structure, since the wall thickness becomes thicker, it is necessary to change the interior space from the general wall, and there is a problem that the effective width of the staircase and the corridor becomes narrow. In addition, there is a problem that it is troublesome to assemble the groundwork and the workability is poor, and it is necessary to bond two gypsum boards, and the workability is poor.

An object of the present invention is to provide a field wall structure capable of maintaining fireproof performance and sound insulation performance and reducing the wall thickness.

[0005]

Means for Solving the Problems In order to solve the above-mentioned problems, a field wall structure according to the present invention has a corrugated steel plate arranged on a surface corresponding to each chamber as an interior base, An interior board is attached to the surface on the indoor side.

[0006]

Since the boundary wall structure is constructed by attaching a board to a corrugated steel plate (corrugated steel plate), the wall thickness can be reduced while maintaining fireproof performance and sound insulation performance. That is,
The corrugated steel sheet has high sound insulation performance, and it is possible to obtain the same sound insulation performance as a gypsum board with a thickness of 1/10 of the board. Further, since the corrugated steel sheet is a non-combustible material and also has fireproof performance, it is possible to exhibit sufficient sound insulation performance and fireproof performance even if the thickness of the entire boundary wall is reduced.

EXAMPLES Examples of the boundary wall structure will be described below with reference to the drawings. 1 is a perspective view showing a part of the boundary wall structure in cross section, FIG. 2 is a vertical sectional view illustrating the boundary wall structure, and FIG. 3 is a plan sectional view illustrating the boundary wall structure.

In the figure, the boundary wall A is constructed so as to partition the chambers 1 and 2. Usually, a floor beam 3 and a ceiling beam 4 are provided at positions where the boundary wall A should be formed, and a lower runner having a U-shaped cross section formed on the upper surface of a floor 5 formed above the floor beam 3. 6 are mounted along the boundary wall to be constructed. An upper runner 7 having a U-shaped cross section is attached to the lower surface of the ceiling beam 4 so as to face the lower runner 6. A heat insulating material 8 is arranged between the lower runner 6 and the upper runner 7, and is held by the flanges 6a, 7a of the respective runners 6, 7. An upper floor 5 is formed on the ceiling beam 4 in the same manner as the floor 5.

The corrugated steel sheet 9 is set to a thickness of 1.2 mm so as to exhibit the same sound insulation performance as that of a plaster board having a thickness of 12 mm, and is formed in a so-called corrugated shape in which irregularities are alternately repeated at a predetermined pitch. ing. Then, the corrugated cross section of the corrugated steel sheet 9 is arranged in the vertical direction, and the recess 9a is formed in the flange 6 of each runner 6, 7.
The corrugated steel sheet 9 is fixed to the runners 6 and 7 at both upper and lower ends by abutting against a and 7a and fastening with tapping screws 10.

By arranging the corrugated steel sheet 9 as described above and fixing it to the runners 6 and 7, the corrugated steel sheet 9 exhibits high rigidity. Therefore, the corrugated steel plate 9 can be continuously attached to the runners 6 and 7 without providing studs or furring strips between the beams 3 and 4.

The corrugated steel plate 9 is attached to the two flanges 6a, 7a of the runners 6, 7 corresponding to the chambers 1, 2. That is, the corrugated steel plates 9 are arranged on both sides of the heat insulating material 8 on the boundary wall A.

A gypsum board 11 is fixed to the inside of the corrugated steel plate 9 on the indoor side. In this embodiment, as the gypsum board 11, a board having a thickness of 10 mm formed by extrusion molding is used.
This gypsum board 11 is brought into contact with the convex portion 9b of the corrugated steel plate 9,
It is fixed to the convex portion 9b through a plate tapping screw 12. When the gypsum board 11 is fixed to the corrugated steel plate 9, the dish tapping screw 12 is used so that the head of the screw 12 is not embedded in the gypsum board 11 and projected into the room.

In the field wall A constructed as described above, the corrugated steel plate 9 made of corrugated steel plate is used, and the upper and lower ends of the corrugated steel plate 9 are fixed to the flanges 6a and 7a of the runners 6 and 7, respectively. Even if a pillar or brace exists at the position of the boundary wall to be configured, the pillar or brace can be avoided to configure the boundary wall A by appropriately setting the distance between the flanges of the runners 6 and 7. Is possible.

That is, as shown in FIG. 3, when there is a column 13 between the floor beam 3 and the ceiling beam 4, for example, the distance between the flanges 6a in the lower runner 6 is determined by the thickness of the column 13 and the corrugation. By appropriately setting the corrugated steel sheet 9 according to the unevenness, when the corrugated steel sheet 9 is fixed to the flange 6a, the convex portions 9a of the corrugated steel sheet 9 can be avoided without interfering with the column 13. is there.

When a brace (not shown) is provided between the floor beam 3 and the ceiling beam 4, the brace can be arranged between the flanges 6a of the runners 6, 7 or between the flanges 7a. By setting the position, the brace can be arranged at a position where interference with the corrugated steel sheet 9 can be avoided.

Further, since the corrugated steel sheet 9 has high rigidity and strength, it can be attached to the runners 6 and 7 arranged above and below without forming a foundation such as a stud or a furring strip, and It is possible to fix the gypsum board 11 to the steel plate 9. Therefore, it becomes possible to improve the workability in constructing the boundary wall A.

Further, a corrugated steel plate 9 is used to form a boundary wall A between the chambers 1 and 2, and then an independent ceiling 14 is formed for each of the chambers 1 and 2. Therefore, the rooms 1 and 2 are shielded by the boundary wall A up to the portion above the ceiling.

[0018]

As described in detail above, in the barrier wall structure according to the present invention, the board is attached to the corrugated steel sheet having high sound insulation performance, so that the fireproof performance preset in the barrier wall is maintained. In addition, it can exhibit high sound insulation performance. Further, even if the corrugated steel plate has a thickness of about 1/10 of the thickness of the gypsum board, the same level of sound insulation as that of the gypsum board can be exhibited, so that the thickness of the boundary wall can be reduced.
