DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound insulation panel which is used as an outer wall material of a building such as a factory, a power plant, a house, and so on, so as to prevent sound in the building from leaking out of the building.

[0002]

2. Description of the Related Art In a conventional sound insulating panel, a pair of sound-insulating plaster boards are mounted in a stepped U-shaped frame material at an interval, and a gap between the plaster boards is filled with a sound absorbing glass wool. There is a configuration in which a metal exterior corrugated sheet is attached to the outer surface of one plaster board. In addition, one aluminum punched plate having a large number of sound holes and a pair of plaster boards are mounted in a frame member having a U-shaped cross section in the order described above,
Glass wool is filled in the gap between the aluminum punching plate and the plaster board, and a honeycomb-shaped hexagonal hole is formed in multiple rows and multiple stages in the gap between the pair of plaster boards, and the thickness is about the thickness between the plaster boards. There is a configuration in which a gap between a plaster board and an outer wall plate is filled with glass wool via a honeycomb core, and a metal outer corrugated plate is attached to an outer surface of the outer plaster board.

In the former sound insulation panel, a plaster board is located in a building, and the sound in the building hardly reaches the glass wool layer with the sound insulating plaster board, and the plaster board may cause the sound to reverberate into the building. In the latter sound insulation panel, an aluminum punched plate is located in the building, and the sound in the building easily passes through the sound holes of the aluminum punched plate and reaches the sound absorbing glass wool layer. However, there is a problem in that the sound that is reverberated is leaked again through the sound holes of the aluminum punched plate into the building. The former and latter sound insulation panels do not use a material having particularly low sound absorption and sound insulation, and have a problem that the sound insulation of low sound is low. or,
Both the former and latter sound insulation panels have a structure in which members such as plaster boards, glass wool layers, and aluminum punched boards are attached to the frame material, so the sound in the building leaks outside through the frame material. There is.

[0004] Each of the sound insulation panels 5 is provided between bone members 53 such as rectangular steel pipes which are juxtaposed at intervals of the width of the sound insulation panels 51.
1 is attached to form a sound insulating panel 51 (FIG. 12).
), The both side edges of the armored corrugated sheet 52 are projected so as to overlap with the bone members 53, and the side ends of the armored corrugated sheet 52 are cut surfaces. The side edge of the armored corrugated plate 52 and the side edge of the frame member 54 are connected by using the same. However, since the connecting member 55 is fixed to the outer peripheral surface of the frame member 54 using a screw 56 or the like, the step between the sound insulation panel 51 and the bone member 53 occurs due to the step generated by the protrusion of the screw 56 or the head of the nail. There is a possibility that a gap is formed between the gaps, and the sound in the building leaks due to the gap, and the sound insulation effect may be reduced.

[0005] In a conventional sound insulating panel 57 in which both side ends of the projecting corrugated sheet 58 are projected so as to overlap with the sheet corrugating sheet 58 of the adjacent sound insulating panel 57, as shown in FIG. Since the side end is a cut surface, the strength of the protruding portion of the exterior corrugated sheet 58 is low. Therefore, storage
During transportation, the protruding portion of the outer corrugated sheet 58 hits other members or equipment and is easily deformed or damaged, which causes a problem in that the sound insulating panel 57 is not properly attached and the sound insulating effect is reduced.

[0006]

In the sound insulation panel according to the fourth aspect of the present invention, the frame material is fitted so that one of the bent portions of the U-shaped frame material is fitted between the rearmost plaster board of the sound insulation panel board and the glass wool layer. Because it is attached to both side end surfaces, the sound passing through the frame material can be shielded by the last plaster board, and the sound leaking to the outside through the frame material is prevented.

A sound insulation panel according to a fifth aspect of the present invention is a sound insulation panel in which bone members are juxtaposed at intervals of the width of the sound insulation panel, and fitted and mounted between the bone members. Since the front end of the bent portion of the corrugated sheet runs along the sound insulation panel board, it is not necessary to attach the front end of the exterior corrugated sheet to the sound insulation panel board with a separate member such as a connector.
When the sound insulation panel is fitted between the bone members and mounted, there is no danger that the heads of screws, needles, etc., which have attached the connecting members between the frame material and the bone member of the sound insulation panel, will protrude, and the frame material and the bone member The gap between the sound insulation panel and the frame material is eliminated, and the sound in the building is not leaked through the gap. Sound insulation and high sound insulation can be achieved. In addition, by aligning the tip of the armored corrugated sheet with the side end surface of the frame material, the strength of the projecting part of the armored corrugated sheet is improved, and the part of the armored corrugated sheet is deformed or damaged during transportation and storage. This makes the sound insulation panel easy to handle.

[0011]

The glass wool layer and the plaster board may be laminated on the foamed aluminum board once each, or may be laminated alternately plural times. In the latter case, alternately laminating the glass wool layer and the plaster board two times at a time provides a sufficient sound insulation effect and a sufficient rigidity as the outer wall material, and is not too thick and easy to handle. A sound-insulating panel of practical thickness. As the armored corrugated sheet, there is a waveform in which a plurality of semicircular projections are projected at predetermined intervals, and a waveform in which a plurality of projections such as a triangle, a square, and a trapezoid are projected to form a waveform. The side edge of the exterior corrugated sheet is a sound insulation panel where the sound insulation panels are adjacent to each other and each of the exterior corrugated sheets is overlapped and installed. There is. In the sound insulation panel to be fitted and installed between the bone members, the end of the exterior corrugated sheet is projected from both sides of the sound insulation panel board, but the tip of the exterior corrugated sheet is bent inward and the frame of the sound insulation panel board is bent It is along the material or the last plaster board, and it is desirable to fix each other.
