Description

[Detailed Description of the Invention] The present invention relates to a sound insulating partition wall for a building, and its purpose is to improve sound insulation and impact resistance.

Partition walls, which are the boundary walls between rooms in concrete buildings such as high-rise residences, buildings, and schools, should preferably have excellent sound insulation and impact strength, but if the above performance is insufficient. Used in large quantities.

The applicant of this application has filed an earlier application entitled "Sound Insulating Partition Wall for Buildings"
(Utility Model No. 54-177948 (Utility Model Publication No. 59-35690)) disclosed a sound insulating partition wall with excellent sound insulation and fire prevention performance consisting of two partition plates inside and outside and three layers of soundproof space. The idea is to improve the above-mentioned sound-insulating partition wall.

In other words, in the above-mentioned composite structure partition wall, when constructing a structure in which two partition plates are joined by intervening architectural bond in the outer soundproof space, the assembly work is easy and the strength and sound insulation of the entire partition wall is improved. However, it is difficult to perfect the impact resistance of the joints of the outer partition plates.

In addition, from the perspective of attenuating sound air vibrations, it is preferable to divide each soundproof space into smaller areas rather than creating a large space that communicates with each other. This increases solid vibration propagation sound, which is actually disadvantageous.

In order to improve the above-mentioned drawbacks, this invention provides each inner partition plate with a vertical rib that does not touch the adjacent partition plate, and creates a joint between the outer partition plates along this vertical rib material. The joint portion is joined to the vertical rib material using adhesive bond, and a sound insulating material is interposed between the adjacent inner partition plate and the vertical rib material.

Next, an embodiment of the present invention will be described based on the drawings.

The sound insulating partition wall 1 is a sound insulating partition wall 1 having a composite structure consisting of two inner partition plates 2, two outer partition plates 3, and three layers of sound insulating spaces 4 and 5 between them. It has a structure that is installed between the wall 7 and the left and right side walls 8.

The two inner partition plates 2 create an inner soundproof space 4 of approximately 50 mm.
are placed opposite each other with a space between them, and approximately
The outer partition plates 3 are placed opposite each other with an outer soundproof space 5 of 29 mm left open. The inner partition plate 2 and the outer partition plate 3 are joined by a construction bond 9 interposed in the outer soundproof space 5, and about 25 mm in the middle part of the inner soundproof space 4.
A flexible sound insulating material 15 made of glass wool with a thickness of .

A pair of opposing angle members 10 extend around the entire circumference of the inner soundproof space 4, forming a ceiling wall 6, a floor wall 7, and both side walls 8.
The peripheral part 2a of the inner partition plate 2 is fixed on the outside of this angle member 10 with a countersunk head screw 12.
It is fixed at Further, a liner material 13 made of gypsum board is installed between each wall 6, 7, 8 and the peripheral edges 2b, 3b of the inner and outer partition plates 2, 3. Building bond is applied between the liner material 13 and each of the walls 6, 7, and 8 as necessary, and building bond 9 is applied between the inner and outer partition plates 2 and 3 along the entire circumference of the outer soundproof space 5. In addition to joining the inner and outer partition plates 2 and 3, the sealing structure between the partition wall 1 and each of the walls 6, 7, and 8 is ensured.

The inner partition board 2 and the outer partition board 3 are respectively an inner partition board 2c and an outer partition board 3 made of gypsum board.
vertical rib members 1 are formed between the butt side edges 2d of the inner partition board 2c.
4 are interposed orthogonally, and the vertical rib members 14 are made to protrude into the outer soundproof space 5 and the inner soundproof space 4.
Here, a vertical rib member 1 protruding into the outer soundproof space 5
4 and the inner partition board 2c are bonded in advance with architectural bond 9b arranged in a fillet shape. A gap is provided between the inner surface 14a of this vertical rib material 14 and the inner partition board 2c facing this inner surface 14a, and this gap is closed with the above-mentioned sound insulation material 15, so that the sound inside the inner soundproof space 4 is Block the propagation of air vibrations as much as possible.

Furthermore, in order to improve the impact resistance of the joint 3e between the abutting side edges 3d of the outer partition board 3c, the joint 3e is made to face the outer surface 14b of the vertical rib material 14, and the outer surface 14b of the vertical rib material 14 is and the outer partition board 3c are bonded together with a construction bond 9 interposed therebetween.

Further, this architectural bond 9 is arranged in such a manner that the vertical rib material 14 and the fillet-shaped architectural bond 9b are buried, and this architectural bond 9 connects the vertical rib material 14, the inner partition board 2c, and the outer partition board 3c. are joined. Further, the bonds 9 are disposed vertically intermittently or continuously.

The vertical rib members 14 are made of a fireproof material made by stacking three strips of gypsum board of the same type as the outer partition board 3c and bonding them with an adhesive. Furthermore, the architectural bond 9 for joining the inner partition board 2c and the outer partition board 3c has a structure in which a gypsum board 9a is interposed between the architectural bonds 9 to accelerate the drying of the bond.

In addition, as shown in FIG. 4, when using the inner partition board 2c of a constant width and the outer partition board 3c of a constant width, by arranging the vertical ribs 14 of the opposing inner partition plates 2 in a staggered manner, It is desirable to divide the inner soundproof space 4 as finely as possible.

The partition boards 2c and 3c of the partition plates 2 and 3 are made of gypsum board with excellent sound insulation, fireproofing, and heat resistance, and the architectural bond 9 is mainly composed of gypsum and bond, such as one made by Yoshino Gypsum Co., Ltd. Use Tiger GL Bond (Gypsum Bond). The thickness of the partition wall 1 of the present invention is, for example, 9 mm for each of the inner and outer partition plates 2 and 3.
and 12mm, and if the inside and outside soundproof spaces 4 and 5 are respectively 50mm and 29mm, the total will be 150mm, which is not as thick as the conventional product, but if the partition wall 1 is 3.
Since it has soundproof spaces 4 and 5 in layers and has high airtightness, it becomes a soundproof partition wall with excellent fireproofing performance, soundproofing performance, and impact resistance.

Since the present invention is configured as described above, it has the following effects.

1. The vertical rib material of the inner partition plate is made to protrude into the inner soundproof space and the outer soundproof space, and in the inner soundproof space, a sound insulating material is interposed between the vertical rib material and the inner partition plate, and in the outer soundproof space, the vertical rib material and the outer partition are interposed. Since the structure is such that architectural bond is interposed between the boards, the inner soundproof space and the outer soundproof space are defined by the positions of the vertical rib members. Therefore, the air vibrations of the sound within the soundproof space are no longer repeatedly reflected, and are attenuated in a short period of time.

Furthermore, the outer and inner partition plates are rigidly attached to each other via vertical rib members, greatly increasing their rigidity, making it difficult for both the inner and outer partition plates to be excited. The sound insulation of the entire wall is greatly improved.

2 The joint between the butt side edges of the partition board of the outer partition plate is aligned with the position of the vertical rib material, and this joint part is bonded to the outer surface of the vertical rib material with a bond, so the joint part of this outer partition plate Even if a large impact load is applied, the joints will not open or shift because they are supported by the rigidity of the vertical ribs via the bond. That is, the impact resistance and strength of the partition wall are significantly improved.

3. Since the joint portion of the outside partition board is supported by the vertical rib material through the relatively thin building bolt, construction work when installing the outside partition board becomes easier.
