[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound insulation partition wall panel and a wall construction method using the same.

[0002]

2. Description of the Related Art Sound insulating partition walls such as high-rise or super-high-rise housing with a ramen structure and room walls of hotel rooms do not use cast-in-place concrete, but rather light steel studs are attached to both sides of which plasterboard etc. It is often constructed by attaching several layers or molded sound insulation partition wall panels afterwards.

Conventionally, as the latter post-formed molded partition wall, as shown in FIG. 5 (A), a concrete-based panel or a ceramic-based molded panel P having ribs R along the longitudinal direction of both ends, Assemble the ribs R side by side so that they do not fit each other, and similarly attach to both sides of the wall. At the time of assembly, a sound absorbing material F such as an incombustible fiber is loaded between the ribs R of the panel P to form a double wall structure, or as shown in FIG. 5B, one side wall surface is assembled. After
In some cases, a sound absorbing material F such as a non-combustible fiber is temporarily fixed to the inside of a wall surface already assembled using a cloth tape or the like, and the panel on the opposite side is assembled. Sound absorbing material F such as incombustible fiber between ribs R
In some cases, the sound absorbing material F such as non-combustible fiber was attached with an adhesive at the time of factory shipment. Further, the joints of the ribs R on both sides had an uneven shape, a continuous shape, or a completely flat shape.

Further, conventionally, there has also been a construction method of a sound insulation partition wall in which a plate-like building material such as a gypsum board is attached to the surface of the panel.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a panel for a sound insulation partition wall, which mainly includes a plate-shaped portion 1a and the plate-shaped portion 1
a composed of protruding ridge ribs 1b, 1c and 1d integrally formed on one side at both longitudinal ends and a central portion of a. For example, pearlite, sand, cement or the like is used as a main raw material and an admixture or the like is used. It is a rectangular shaped pearlite mortar-based molded panel that uses the main material as an auxiliary material and is entrained with a large number of bubbles inside to make it lightweight, fire-resistant, and sound-insulating.

As is apparent from FIG. 2, inside the plate-like portion 1a and the ribs 1b and 1c at both ends of the panel 1 for the sound insulation partition wall, in order to increase structural strength and prevent shrinkage cracks, welding is performed. The wire mesh 1e is arranged,
Each of the ribs 1b, 1c and 1d is provided with a fine deformed bar 1f to enhance the structural strength in the longitudinal direction.

A non-combustible fiber sound absorbing material 2 such as glass wool or rock wool is filled in the recessed space between the ribs 1b and 1c at both ends and the central rib 1d. The non-combustible fiber sound absorbing material 2 is integrally packed at the same time when the sound insulating partition wall panel 1 is molded.

A convex portion 1b 'is formed along the longitudinal direction on the side surface of the rib 1b, and a concave portion 1c' is formed along the longitudinal direction on the side surface of the rib 1c on the opposite side. Has been done. At the bottom of the concave portion 1c ', for example,
A gasket 1g made of silicone sponge rubber or the like is fixed.

FIG. 3 shows an example of the construction of the sound insulation partition wall by the sound insulation partition wall panel 1. First, as shown in FIG. 4, the upper surface 3 of the floor slab of the building structure and the floor slabs and beams are separated. The L-shaped metal fittings 5 and 6 are fixed by using anchor bolts 5a and 6a which are planted at predetermined positions on the lower surface 4.

Next, with the L-shaped metal members 5 and 6 being sandwiched,
The sound insulating partition wall panel 1 is attached from both sides thereof with tap screws 7 and 8 to form a double structure wall. In this case, as is clear from FIG. 3A, the sound insulation partition wall panels 1 on both sides are arranged so as to be offset from each other.

Subsequently, board-type base materials 9 and 10 such as gypsum board, various fiber boards, and plywood are attached to the outer surface of the sound insulation partition wall panel 1 attached as described above with screws or an adhesive. Attach it, and then on top
For example, interiors 11 and 12 such as cloth sticking or painting finish are provided to form a sound insulation partition wall. Instead of using the board-based base materials 9 and 10, a decorative board-based finishing material can be applied instead.

If it is desired to further improve the sound insulation performance of the sound insulation partition wall, a vibration insulation mat (not shown) in which fibers are entangled with each other is sandwiched on the outer surface of the panel 1 for the sound insulation partition wall, and then the sound insulation partition wall panel 1 is placed thereon. It is preferable that the above-mentioned board-based base material is attached to the above, and the interior is further applied. In this case, the vibration insulating mat and the board-based base material may be attached in advance and then attached to the sound insulation partition wall panel 1. Further, instead of the board-based base material, a decorative board-based finishing material may be attached to the sound insulation partition wall panel 1 by previously bonding the vibration insulating mat or the back surface of the decorative board-based finishing material.

【The invention's effect】

1) Since the rib of the protruding ridge is integrally formed on one surface of the central portion in the longitudinal direction of the plate-shaped portion, it is possible to prevent the sound insulation performance from being deteriorated in the middle sound range due to the resonance transmission of the plate due to the weight reduction. 2) When the panel is molded, since the non-combustible fiber sound absorbing material is integrally loaded into the recessed space between the ribs, not only the work of installing the sound absorbing material at the work site at the time of construction is unnecessary but also the panel and the sound absorbing material Since the integration of the sound absorbing material is improved, the sound absorbing material is prevented from slipping off and the sound insulation performance can be prevented from being deteriorated. 3) At the work site, if the sound absorbing material is sized and cut into the back surface of the panel and then fitted, or if a sound absorbing material such as non-combustible fiber is inserted into the double wall space, the non-combustible fiber powder scatters and the body becomes itchy and absorbs into the body However, this is not preferable in terms of labor environment hygiene, but the wall construction method using this sound insulation partition panel does not directly handle sound absorbing materials such as non-combustible fibers, so this situation is rare and the working environment is greatly improved. . 4) Since the gasket is fixed to the bottom of the concave portion formed on the rib side surface of the panel end when the panel is molded, not only the gasket mounting work at the time of construction is unnecessary, but also the gasket mounting accuracy is ensured, There is no sound leakage from the joints between the panels and the sound insulation performance is improved. 5) Since a large amount of air bubbles were carried inside the main material using pearlite, sand, and cement as the main raw materials and admixtures as auxiliary raw materials, it was lightweight and easy to carry and work, and also excellent in fire resistance. The panel can be configured. 6) Even when a calcareous raw material is used as the main material and an aerated concrete panel using a siliceous raw material with a foaming agent and an admixture is used, a panel that is lightweight, has good transportability, good workability, and is highly fire resistant is constructed. be able to. 7) Since the welding wire mesh is arranged inside the plate-shaped portion and the ribs at both ends thereof, it is possible to enhance the structural strength of the panel and prevent shrinkage cracks. 8) Since the fine deformed bar is arranged inside each rib, the structural strength in the longitudinal direction of the panel can be increased.
