Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition wall structure, and more particularly to a dry partition wall structure in which studs are aligned in a single row at a wall core position and board building materials are attached to the studs. It is a thing.

[0002]

2. Description of the Related Art As a partition wall for a dry construction method in a building or a work, a partition wall having a frame structure in which a board building material such as a gypsum board or a calcium silicate plate is attached to a wooden or steel stud is widely put to practical use. ing. The studs are arranged in a single row, a plurality of rows or in a zigzag at a predetermined interval in the wall core direction,
The upper end and the lower end of the studs are fixed to the upper and lower horizontal pulling members, horizontal bridge members, runners, and the like, respectively. The board building material forming the wall surface is integrally attached to the stud by nails, screws, staples, or an adhesive.

FIG. 3 is a cross-sectional view showing a partition wall of a single-row stud having a conventional structure using wooden studs. The partition wall 101 shown in FIG. 3 (A) is provided with wooden studs 102 of wooden timbers aligned in a single row at the center of the wall. The studs 102 are spaced apart from each other by a predetermined distance D and are located on the back surface of the side edge portion and the back surface of the central portion of the subbing board building material 103. Underlay board building material 103
Are integrally attached to the stud 102 by a fastener 110 such as a nail. The upholstery board building material 104 is stapled and / or
Or it is attached on the board building material 103 with an adhesive or the like,
Interior finishing material 105 such as paint or cloth is
Will be constructed on top. Generally, the spacing D between the studs 102 is about 300 m.
m or 450 mm, the stud 102 has at least about 50
A thickness t of about mm is required for structural strength. Therefore, the wall thickness T of the partition wall 101 is set to a dimension of about 100 to 150 mm. The width W of the board building material 103 usually has a dimension of about 600 mm or 900 mm, and the side edge 103a and the central portion 103b of the board building material 103 are fixed to the stud 102, respectively. As another conventional partition wall, a partition wall 101 in which wooden studs 102 are built in a staggered arrangement is shown in FIG. 3 (B). The studs 102a supporting the board building material 103 on one side and the studs 102b supporting the board building material 103 on the other side are arranged in a staggered manner in the hollow portion 115 of the partition wall 101. Stud 10
The mutual distance D of 2 is set to 1/4 of the width W of the board building material 103, and the side edge 103a and the central portion 103b of the board building material 103 are
Fixed to studs 102, respectively.

Since this type of partition wall constitutes a boundary wall which partitions each room of a building, the sound insulation effect of the partition wall which prevents noise transmission between adjacent rooms has been particularly emphasized in recent years. In the partition wall structure (Fig. 3 (A)) in which the studs 102 are arranged in a single row at the wall core position, the noise in the adjacent room not only propagates to the wall surface of the other room through the air layer of the hollow portion 115, but also
Solids propagate to the wall surface of the other room through the studs 102 and re-radiate. On the other hand, in the partition wall structure in which the studs 102 are arranged in a staggered manner (Fig. 3 (B)), the solid propagation route of the studs 102 is a gap 10.
Since it is blocked by 6, the sound insulation effect of the partition wall 101 is
Greatly improved compared to single-row stud partition walls.

[0005]

However, the staggered studs 102 require a dimension of at least about 50 mm in terms of structural strength, similar to the partition wall of a single row stud (FIG. 3 (A)). In the partition wall structure of the row studs, the dimension of the wall thickness T is necessarily increased as compared with the single row stud arrangement because the gap 106 needs to be secured on one side of the studs 102.

Therefore, for a partition wall whose wall thickness T is limited to about 100 to 110 mm, the partition wall structure of a single row stud must be adopted, and the sound insulation effect equivalent to that of the staggered row stud partition wall structure is obtained. Could not be achieved. The present invention is
It was made in view of such circumstances, and the purpose thereof is to have a wall thickness equivalent to that of a single-row stud partition wall and to achieve a sound insulation effect equivalent to that of a staggered stud partition wall. The purpose of the present invention is to provide a partition wall structure.

[0007]

In order to achieve the above-mentioned object, the present invention is a partition wall of a dry construction method in which studs are built in a hollow portion of the partition wall at a predetermined interval and a board building material is attached to the stud. In the structure, the studs are aligned in a single row at a wall core position with a mutual spacing (D) corresponding to 1/2, 1/3 or 1/4 of the width (W) of the board building material, A pavement board made of sound absorbing material is arranged on both sides of the stud, and the board building materials on each side of the partition wall are arranged at positions relatively displaced in the wall core direction by at least one span of the stud, and locked. Only the both side edges of the board building material are fixed to the studs by the fasteners, and the clapboard inserted between the both side edges of the board building material and the studs is tightened by the fasteners. Or, it is held in a compressed state by the driving force and the inside of the board building material There is provided a partition wall structure, characterized in that the siding plate inserted between the space portion and the stud is held in a compressed state by the surface pressure of the board building material.
Preferably, the mat sheet is made of glass tissue, glass wool or rock wool band-shaped molding material having a specific gravity of 10 to 350 kg / m ³ , and has a thickness of about 3 to 10 mm when uncompressed and about 2 to 6 mm when compressed. Have.

According to the above configuration of the present invention, the partition wall is
A single row of studs is provided, with board building material placed on each side of each stud. The side edge portion of the board building material compresses the sheet board by a driving force or a tightening force of a locking tool such as a nail or a screw, and an intermediate portion of the board building material compresses the sheet board by the surface pressure of the board building material. The board building material on each side of the partition wall is arranged at a position relatively displaced in the wall core direction by at least one span of the stud, and only both side edges of the board building material are fixed to the stud by the locking tool. The pavement plates arranged on at least one side act as unsupported fulcrums that can absorb the vibration of the board building materials, and the board building materials on both sides of the partition wall are inserted in a compressed state only by the surface pressure of the board building materials. It is acoustically insulated by the mattress. Thus, the board building material exerts sufficient out-of-plane rigidity as a wall component over the entire wall surface, similar to the conventional partition wall, and the sound insulation effect of the partition wall is greatly improved as in the case of the staggered stud partition wall. .
