Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a sound insulation partition wall of a building, and provides a partition wall having high sound insulation properties and high fireproofing or fireproof property while being easy to construct.

《Prior art》 The partition wall, which is the boundary wall between rooms in a concrete structure such as a high-rise house / building / school / hotel or hospital, is excellent in terms of sound insulation and fire protection or fire resistance. Is desired.

As such a partition wall, there is a partition wall disclosed in Japanese Utility Model Publication No. 59-35690 previously proposed by one of the applicants of the present invention.

As shown in FIG. 4, an inner partition plate (51) made of gypsum board is fixed to both side surfaces of a runner material (50) fixed so as to face a ceiling wall and a floor wall. An outer partition plate (52) made of gypsum board is placed outside the (51) with a certain gap to make the space between the inner and outer partition plates an outer soundproof space (53) and the inner partition plate an inner soundproof space (54). ), The outer partition plate (52) is fixed to the inner partition plate (51) with a plaster-based adhesive (55).

<Problems to be solved> In the conventional sound insulation partition wall, there was an outer sound insulation space (53) sealed between the inner and outer partition plates (51) and (52) depending on the frequency. (53) becomes a resonance space and transmits the vibration of the outer partition plate (52) to the inner partition plate (51),
Furthermore, the vibration is amplified in the inner soundproof space (54), the inner partition plate (51) on the opposite side is vibrated, and the vibration is transmitted to the outer soundproof space.
Since it may be transmitted to the outer partition plate (52) via the (53), it has been found that there is a problem that the sound insulation is deteriorated. This problem occurs even when a sound absorbing material such as glass wool is arranged in the inner soundproof space (54).

<Means for Solving Problems> The present invention aims to provide a partition wall that has excellent sound insulation and is resistant to fire. Therefore, narrow plasterboard on both sides of the runner material. The base material made of steel is laid across the upper and lower runner materials at appropriate intervals in the length direction of the runner material in a state where the base materials on both sides are located in a zigzag pattern.
Glass wool is placed in the space formed by the thickness of the runner material, two gypsum boards inside and outside the base material, and the joint ends of the outer gypsum boards and the inner gypsum boards are staggered in plan view. Place the wall material that is closely adhered so that the inner gypsum board is bonded and fixed to the base material with a gypsum adhesive, and at least one of the thickness and material of the outer gypsum board is different from the inner gypsum board. It is characterized by that.

<Operation> In the present invention, since the inner and outer gypsum boards constituting the wall material are in close contact with each other, no resonance space is generated between the inner and outer gypsum boards.

Moreover, since at least one of the thickness and the material of the inner and outer plaster boards is different, the resonating frequencies of both plaster boards are different, and the joint ends of the outer plaster boards and the joint ends of the inner plaster boards are staggered in plan view. Since the gypsum boards are arranged at the same position, both gypsum boards do not resonate. In addition, the base material bridged over the upper and lower runner materials is composed of narrow gypsum board, and this base material is arranged at appropriate intervals in the longitudinal direction of the runner material, so that the wall surface has one space. In addition, since the base material is arranged in a zigzag pattern on both sides of the runner material, the space is formed in a detour shape. This prevents the sound in one room from being transmitted to the other room.

Moreover, since the partition wall is composed only of non-combustible materials of gypsum and glass wool, it serves as a fireproof material or a fireproof material.
