Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound-insulating partition structure for a bearing wall.

[0002]

2. Description of the Related Art In an industrialized house, the sound insulation performance of outer walls and windows has been improved and the external noise has been reduced.
The noise between the rooms is becoming more noticeable.

Conventionally, among such sound insulation wall structures in consideration of sound insulation, a load-bearing wall portion in which a brace is provided between vertical columns of a skeleton, as shown in FIG. It is known that a stud e is erected between the runner c provided on each of the b and the brace d so as not to be buffered by the brace d, and an inner wall material f is attached to both side surfaces of the stud e. In this case, the stud e is located between the two supporting plate columns g.
A plurality of stud bodies h cut so as not to buffer the brace d are sandwiched and adhered.

[0004]

However, in the case of the above-mentioned conventional sound-insulating wall structure of the load-bearing wall portion, the inner wall material f attached to both side surfaces of the stud e is connected via the stud e. Vibration of the sound transmitted to the inner wall member f is transmitted to the other inner wall member f through the stud e, so that a so-called sound bridge is formed, which causes a disadvantage that sufficient sound insulation cannot be obtained.

The present invention has been made in view of the above circumstances, and has as its object to provide a sound-insulating partition wall structure in a load-bearing wall portion which does not form a sound bridge and can exhibit excellent sound insulating properties. And

[0006]

The sound-insulating partition wall structure in the load-bearing wall of the present invention for solving the above-mentioned problems has a load-bearing surface formed by a brace between vertical columns such as an independent column and a frame. In the load-bearing wall portion, groove-shaped runners having a U-shaped cross section are provided so as to oppose each other between the vertical columns at the respective positions sandwiching the load-bearing surface, and there is an interval between these groove-shaped runners. A plurality of studs are fixed so that independent sound insulating inner wall bases are formed on both sides of the bearing surface, a sound absorbing material is provided inside these sound insulating inner wall bases, and an inner wall material is attached outside the sound insulating inner wall bases. Things.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show a construction procedure of a sound-insulating partition wall structure in a bearing wall portion, and FIG. 4 shows a completed state of the construction of the sound-insulating wall structure.

That is, the sound-insulating partition wall structure has a bearing surface 2 having a bearing surface 2 between the independent columns 1.
Between the independent pillars 1 at the respective positions sandwiching the
The studs 4 are fixed between the groove-shaped runners 3 to form a sound-insulating inner wall base material A on both sides of the bearing surface 2.
And the inner wall material 6 is attached to the outside of the sound insulation inner wall base A.

The load-bearing surface 2 is constructed by bridging a brace 21 between the independent columns 1 facing each other. Also,
A column link 22 is provided between the lower ends of the independent columns 1.

The groove-shaped runner 3 is formed of a long steel plate having a U-shaped cross section. The groove-shaped runner 3 has a length equal to or less than the length from the floor surface 7 to the ceiling ridge 8, and is provided at each position across the load-bearing surface 2 by a fixing bracket 30 as shown in FIGS. 5 and 6. 1 is fixed with screws 9. The fixing bracket 30 includes a metal fitting body 30a made of a steel plate.
One pillar holding piece 30b is formed in the center of one surface of the first surface, and two runner holding pieces 30c are formed on both sides of the other surface. The groove-shaped runner 3 is held between the runner holding pieces 30c located on both sides of the bearing surface 2 with the independent pillar 1 held between the pillar holding pieces 30b of the fixture 3. .

In this state, the groove 31 of the groove-shaped runner 3 fixed between the independent pillars 1 at each position across the bearing surface 2
They are made to face each other.

The stud 4 is formed of a long steel pipe having a rectangular cross section. This stud 4
As shown in FIG. 7, it is fitted between the grooves 31 of the opposed grooved runners 3 and fixed with screws 9 at predetermined intervals. As shown in FIG. 8, partition runners 40 are fixed to the floor surface 7 along the pillar connection 22 on both sides of the pillar connection 22 with screws 9.

As a result, the sound insulating inner wall base A is formed on both sides of the bearing surface 2. The sound absorbing material 5 is a sound insulating inner wall base A
Is provided in the gap between the inner wall base A and the bearing surface 2. This sound absorbing material 5 completely separates both sound insulating inner wall bases A provided with the bearing surface 2 therebetween.

The inner wall material 6 is fixed to the studs 4 of the sound insulation inner wall base A. One or two inner wall members 6 are attached to each surface. As the inner wall material 6, veneer plywood or gypsum board is used. When two pieces are to be attached, the inner wall material 6 attached to the inner side is used.
For example, a soundproof sheet may be used.

When constructing the sound insulating wall structure, first,
The fixing bracket 30 is attached to the independent pillar 1, and the fixing bracket 30 is attached.
, The groove runner 3 is fixed. Studs 4 are fixed between the grooved runners 3 at predetermined intervals. The partition runners 40 are fixed to the floor surfaces 7 on both sides of the pillar link 22 to form the sound insulating inner wall base A. Next, a sound absorbing material 5 is inserted from between the studs 4 of one of the sound insulating inner wall bases A, and the sound absorbing material 5 is provided in a gap between the sound insulating inner wall base A and the bearing surface 2 to divide the two sound insulating inner wall bases A. I do. Then, the inner wall material 5 is fixed to each surface of both the sound insulating inner wall bases A.

According to the sound-insulating partition structure thus constructed, the sound-insulating inner wall base A is provided independently on both of the bearing surfaces 2.
Therefore, the inner wall material 6 attached to the sound insulating inner wall base A does not connect via the stud 4. Therefore, the so-called sound bridge, in which the vibration of the inner wall material 6 on one surface is transmitted to the inner wall material 6 on the other surface, does not occur, and excellent sound insulation can be obtained.

In this embodiment, two independent columns 1
Although the case where the bearing surface 2 is formed between them is described,
As shown in FIG. 9, one of the independent columns 1 may be a shaft set 11. In this case, the vertical rail 12 of the inner wall frame is
Will be located, so that the vertical bracket 12
0 is fixed, and the channel runner 3 is fixed. However, when the fixing bracket 30 is fixed to the vertical rail 12, the column holding piece 30b of the fixing bracket 30 becomes an obstacle. Therefore, the column holding piece 30b is extended flat, and then the column holding piece 30b is connected to the vertical rail. 12 is fixed with a screw 9.

[0019]

As described above, according to the sound-insulating partition wall structure of the load-bearing wall portion of the present invention, the load-bearing wall portion having the load-bearing surface is provided between the vertical columns such as the independent columns and the frame members on both sides of the load-bearing surface. The sound-insulating inner wall base is formed independently, and the sound-absorbing material is provided inside these sound-insulating inner wall bases and the inner wall material is stuck outside the sound-insulating inner wall base. There is no so-called sound bridge transmitted to the material, and excellent sound insulation can be obtained.
