Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a reinforcing structure for partition walls in housing complexes, etc., and is primarily aimed at improving the out-of-plane bending rigidity of the partition walls.

(Prior Art) In general, studs 2 made of channel steel with lips are erected at predetermined intervals along one partition l as shown in FIG. Partition walls 3, 3 made of fiber-reinforced gypsum board are arranged on both sides, and each stud 2 and parting wall 3 are joined to each other, or as shown in FIG. Studs 2 made of channel steel with lips are erected at predetermined intervals along The wall 3.3 consists of studs 2a that are joined only to one parting wall 3, and studs 2b that are joined only to the other parting wall 3, and glass wool 4 as a sound absorbing material is filled between them. Some structures are known.

(Problems to be Solved by the Invention) In the above conventional partition wall structure, in the former case, since the studs 2 are tightly connected to the partition walls 3 on both sides, the noise generated in one room is transmitted to that room. There is a problem in that the sound is directly transmitted from the inner parting wall 3 to the other room via the studs 2 and the other parting wall 3, resulting in a significant reduction in sound insulation.

The latter was proposed as a solution to this problem, and since the studs 2a and 2b were each connected to only one parting wall 3, the above-mentioned directly propagated sound could be prevented, and in addition, sound insulation was achieved. Sound insulation is improved by filling the hollow part with material 4, or because there is no member height in the out-of-plane direction of stud 2 considering the thickness, the moment of inertia of area in that direction is not very large, and the rigidity is The problem of shortage and the problem of parting wall 3
However, the problem was that the material had poor fracture resistance and impact resistance.

The present invention was made in order to solve the above-mentioned problems with the conventional structure of the partition wall. 1. It increases the rigidity of the partition wall and improves performance such as impact resistance without increasing the thickness of the partition wall. The purpose of this invention is to provide a reinforcing structure for partition walls.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a reinforcing structure for a partition wall used in a partition section of an apartment complex, in which one of the parting walls of the partition wall is Studs that are only in contact with one parting wall and studs that are only in contact with the other parting wall are arranged alternately at predetermined intervals, and the sides of each of the studs that are not joined to the parting wall are The structure is characterized in that a reinforcing metal fitting having a dimension in the wall thickness direction within the distance between the partition wall and the partition wall is fixed thereto, thereby improving the rigidity in the out-of-plane direction.

Further, impact resistance can also be improved by integrally disposing thin steel plates on the outer surfaces of the partition walls.

Furthermore, in addition to the above configuration, if the hollow portions between the studs are filled with a sound absorbing material, it is possible to achieve even better sound insulation performance.

(Example) Hereinafter, an example according to the present invention will be described in detail based on the attached drawings.

FIG. 1 is a cross-sectional view showing a reinforcing structure for a partition wall according to an embodiment of the present invention, and FIG. 2 is a partially cutaway perspective view of the same. 11 and
Among the inner boundary walls 11, studs 12a are abutted only to the - side of the boundary wall 11a, studs 12b are abutted to only the other boundary wall 11b, and the studs 12a and 12b are connected to the boundary wall llb and It is composed of a reinforcing metal fitting 13 fixed to a surface not in contact with the lla, and a sound absorbing material 14 filled between the mutually opposite studs 12a and 12b.

The parting wall 11 is formed of a noncombustible material such as GRC (glass fiber reinforced concrete), and studs 12a and 12b alternately arranged between the parting walls 11a and llb are provided with lips in this embodiment. Molded from channel steel.

In addition, the stud 12a and the partition wall 11b or the stud 12b
The reinforcing metal fitting 13 having a dimension L2 in the wall thickness direction within the distance L1 between the partition wall 11a and the partition wall 11a is formed into a hat-shaped or C-shaped cross section, as illustrated in FIGS. 3(a) and 3(b). ,
1 and 2 show an example of the reinforcing hardware 13 shown in FIG. 3(b).

In this embodiment, a plurality of reinforcing metal fittings 13 are fixed at predetermined intervals along the length direction of the studs 12a and 12b without contacting the opposing partition walls 11.

In addition to the example shown in FIG. 3, the reinforcing metal fittings 13 are
It may have a continuous shape corresponding to the length of a and 12b.

Next, FIG. 4 is a cross-sectional view of a partition wall lO showing another embodiment according to the present invention, and the destruction resistance of the partition wall lO,
1.Both boundary walls 11a, ll to increase impact resistance and rigidity.
A thin steel plate 15 is integrally fixed to the outer surface of b, that is, the indoor surface.

Finishing boats 16 are attached to the inner surfaces of both rooms of the partition wall 10 constructed as described above.

Note that the dimension of the reinforcing hardware 13 in the wall thickness direction may be formed to any dimension according to the design conditions within a range that does not come into contact with the opposing partition wall, and the thin steel plates 15 may be provided by stacking a plurality of them. It goes without saying that various modifications are possible without departing from the gist of the present invention.

(Effects of the Invention) As described above in detail, the reinforcing structure of the partition wall according to the present invention has the effect of increasing the cross-sectional area in the out-of-plane direction of the studs. 1 on the side where the parting walls of the studs arranged alternately between the walls are not abutted.
It is a structure in which reinforcing metal fittings having a dimension in the wall thickness direction within the distance between the stud and the parting wall are fixed, and the rigidity in the out-of-plane direction is improved.

In addition, by integrally fixing thin steel plates to the outer surfaces of the partition walls, it is possible to further improve not only fracture resistance and impact resistance but also rigidity.

Furthermore, in addition to the above configuration, if the hollow portions between the studs are filled with a sound absorbing material, it is possible to achieve even better sound insulation performance.

In addition, since the reinforcing hardware is provided within a range that does not come into contact with the opposing partition walls, the sound insulation performance will not be impaired.
