Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interior system having high sound insulation performance in RC (steel reinforced concrete), SRC (steel reinforced concrete) or S (steel frame) buildings.

[0002]

2. Description of the Related Art As a conventional sound insulation interior system, for example, as shown in FIG. 10, a board having sound insulation performance is attached to a wall base material such as a stud which has been subjected to vibration isolation processing. The edge of the field is suspended from vibration and the floor is a dry-type vibration-absorbing floor made of rubber, etc., or a wet-type floating floor where concrete is cast on glass wool or rock wool (not shown).
The sound insulation structure which consisted of was adopted. In addition, as shown in FIG. 11, a conventional interior system fixes a U-shaped runner to the ceiling and floor, fits a box-shaped or C-shaped cross-section stud, and forms a plate-like material such as gypsum board on the surface. There was a partition wall structure fitted with a finishing material.

[0003] However, the above-mentioned conventional method of attaching a board to a stud has not only low sound insulation performance but also a large number of parts (members), and it is constructed by a wide variety of occupations. There are problems such as easy
In addition, the conventional ceiling that suspends the ceiling edge from the upper floor slab with vibration isolation has a small sound insulation effect because it is directly suspended on the slab,
There are many parts (members), many types of work, and there are many variations in effects due to construction accuracy. In addition, among the above-mentioned conventional floor sound insulation structures, dry-type floating floor structures have anti-vibration rubber on the entire slab. In order to do so, it is not only necessary to use a lot of anti-vibration materials but also to support it in the center of the slab. As a result, there are problems such as an increase in the floor surface. On the other hand, in the case of the dry floating floor structure, not only the weight becomes heavy due to the driving of concrete, but also resonance occurs around 10 to 20 Hz or the sound insulation effect is reduced. There were problems such as low cost.

Further, in the conventional interior system as shown in FIG. 11, since the width of the runner is slightly larger than the width of the stud, the finishing material spreads out at the runner portion and comes out to the outside, or the stud is raised to the ceiling height. Not only must it be cut off at the site, but also the work is divided into light iron work and board work, resulting in multiple parts (members) and multiple work types.

[0005]

1) Since the upper and lower ends of the sound insulation panel are supported only on the slab near the wall or beam of the building, or only on the wall or beam near the slab, the sound insulation performance is improved and studs are not required. Not only that, the size from the skeleton wall to the interior finishing surface can be reduced to increase the living room space. 2) A slit is formed at the upper end of the sound insulation panel, and the slit is fitted to a runner fixed to a slab, a wall or a beam,
Since the vibration isolator is inserted between the slit and the runner, it is easy to attach and remove the sound insulation panel. Also, it can be easily attached to an existing building. 3) Since both ends of the ceiling panel are configured to be attached only to the upper end of the sound insulation panel, not only the sound insulation performance is improved, but also the ceiling panel is not hung from the upper floor slab through the suspension type vibration isolating rubber. This eliminates the need for inserts and the like, and makes attachment and detachment extremely easy. 4) Since the slab near the wall or beam of the building or the wall near the slab is configured to support the short side ends of the long floor panel only on the short side, not only the sound insulation performance is improved, It can be easily constructed with few supporting points. 5) To provide a lightweight and high-rigidity panel, in which the floor panel is composed of an upper plate, a lower plate, and ribs forming a large number of hollow portions by joining these face plates in parallel with each other at predetermined intervals. Can be. 6) Since the vibration isolating support is performed by the vibration isolating rubber, the supporting plate integrally attached to the rubber, and the supporting member with the vibration isolating rubber including the leveling bolt screwed to the supporting plate, the floor panel is supported. Leveling can be easily performed. 7) Since slits are formed at the upper and lower ends of the studs, the slits are fitted to runners fixed respectively to the slab ceiling surface and the slab floor surface of the partition portion, and the partition panel is attached to the stud. Labor saving of wall base installation, improvement of sound insulation performance, smoothing of finished board,
There are effects such as a reduction in residual material generated in the mounting process and a flexible response to interlayer displacement.
