Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION Conventionally, a partition wall that divides a space in a building has been used in order to effectively use the inside of the building.
This partition wall is generally used as a sound-insulating wall in which a sound-insulating material such as glass wool is present in order to prevent sound from entering from the outside. The present invention relates to a spacer for a sound insulation wall used when making the sound insulation wall.

[0002]

2. Description of the Related Art A conventional sound insulation wall will be described with reference to FIG.
In the figure, 1 is a partition wall which is an example of a sound insulation wall. Explaining the structure of the sound insulation wall 1, an elongated metal groove-shaped runner 3 having a length equal to the length of the sound insulation wall 1 is arranged at an appropriate position on the floor 2 of the building, and is fixed on the floor 2 by an appropriate fixing means. .
This groove-shaped runner is composed of a bottom piece 3a, a front standing piece 3b and a rear standing piece 3c standing upright from both ends of the bottom piece 3a. The bottom piece 3a of this groove-shaped runner 3
A plurality of hollow metal quadrangular studs 4 are stood up alternately (staggered). That is, the first stud 4 ₁
It is placed on the bottom piece 3a of the runner 3, and its front side surface 4
a is in contact with the front standing piece 3b of the runner 3, and the rear side surface 4b is not directly in contact with the rear standing piece 3c of the runner 3 but is connected to the rear standing piece 3c via the spacer 6. ing.

A second stud 4 ₂ is placed on the bottom piece 3 a of the runner 3 with a predetermined distance from the first stud 4 ₁ and its front side surface 4 a has a front standing piece of the runner 3. 3b
Is connected to the front standing piece 3b via the spacer 6 without directly contacting the rear side surface 4b, and the rear side surface 4b is connected to the rear standing piece 3 of the runner 3.
It is in direct contact with c. A third stud 4 ₃ is erected on the runner 3 at a predetermined distance from the second stud 4 _{2 in the} same manner as the stud 4 ₁ . The fourth stud 4 ₄ is spaced apart from the third stud 4 ₃ by a predetermined distance.
It is erected on the runners 3 in the stud 4 ₂ a similar manner. In this way, the first studs 4 ₁ and the third studs 4 ₂ erected on the runner 3 are attached to the rear wall 5b made of gypsum board.
Is stretched. As a result, a gap s is created by the spacer 6 between the stud 4 ₁ and the rear wall 5a and between the stud 4 ₃ and the rear wall 5b. A front wall 5a made of gypsum board is stretched on the second studs 2 ₂ and the fourth studs 4 ₄ standing on the runner 3. As a result, a gap s is formed by the spacer 6 between the stud 4 ₂ and the front wall 5a and the stud 4 ₄ and between the stud 4 ₄ and the front wall 5a. Further By stretched the front wall 5a and the rear wall 5b to each stud 4 _1, 4 _2, 4 _3, 4 _4,
A gap L is created between the front wall 5a and the rear wall 5b.

A sound insulating material 7 made of glass wool, for example, is disposed in the gap L to complete the sound insulating wall. This sound insulation material 7
Passes through the gap s between the studs 4 ₂ and the front wall 5a, then goes to the rear wall 5b through the gap s between the studs 4 ₃ and the rear wall 5b, and the sound insulating material 7 passing through the gap s is Further toward the front wall, passing through the gap s between the stud 4 ₄ and the front wall 5b,
5a and the rear wall 5b. That is, the sound insulating material 7 is
They are arranged in a meandering manner from the front wall 5a to the rear wall 5b and then from the rear wall 5b to the front wall 5a. Since the sound insulating material 7 is arranged in a meandering manner in this manner, the front wall 5a, the stud 4, and the rear wall 5b are completely cut off by the sound insulating material 7 and are not directly connected.

Therefore, the sound generated on the front wall 5a is blocked by the sound insulating material 7 and is not transmitted to the rear wall 5b, and the sound generated on the rear wall 5b is not transmitted to the front wall 5a. By arranging the sound insulating material 7 in a meandering manner, a space d ₁ is formed between the front wall 5a and the sound insulating material 7, and a space d ₂ is formed between the rear wall 5b and the sound insulating material 7. The space d ₁ can absorb some of the sound generated in the front wall 5a, and the space d ₂ can absorb the sound generated in the rear wall 5b, thus enabling sound insulation. Thus, the spacer plays an important role in arranging the sound insulating material 7 in a meandering manner between the front wall 5a and the rear wall 5b.

[0006]

As shown in FIGS. 6 and 7, the conventional spacer 6 that plays an important role in this way has a runner contact piece 6a that contacts the front standing piece 3a of the runner 3, as shown in FIGS. Have. Upper and lower ends of the runner abutting piece 6a are bent to form spacing holding pieces 6b, 6b. The center portion of the spacing piece holding 6b is cut out to form a cutout portion 6d,
The stud 4 is fitted into this notch and stopped by the stoppers 6c and 6c. Spacer 6 with such a shape,
In order to mount it between the runner 3 and the stud 4, as shown in FIG. 7, the front standing piece 3 of the runner 3a should be held with one hand.
While unfolding a, hold the spacer 6 with the other hand and press it between the stud 4 and the front standing piece 3a of the runner 3.
As described above, there is a problem in that the spacer 6 has to be attached to the stud 4 with both hands and the spacer 6 has to be pushed in, which is inconvenient for the attachment. In addition, a scaffold that reaches the ceiling is required to mount the spacer 6 between the runner 3 and the studs 4 arranged on the ceiling, and working at a high place on this scaffold is dangerous and the scaffolding is dangerous. Since it has to be manufactured, there is a problem that construction costs are high. The present invention aims to solve such problems.
