Description

[Detailed Description of the Invention] The present invention relates to a partition panel, and an object of the present invention is to provide a panel that has good sound absorption and heat insulation efficiency and can be provided at a low cost.

In recent years, the use of storage compartments and partition panels to divide large spaces has become common.
Sound absorption and insulation of the divided rooms had become a problem.

In view of the above-mentioned problems, the present invention aims to provide a panel with sound absorption and heat insulation effects, which absorbs noise from within the compartment and eliminates reflected sound, and also blocks noise from outside the compartment. It is made up of panels that have excellent heat insulation effects by suppressing heat transfer inside and outside the compartment.

That is, the partition panel of the present invention has a horizontal frame and a vertical frame each having a cross-sectional shape in which an L is connected to both ends of a U-shape, and the tip of the L is directed inward. Further, the upper and lower sides of the core plate are installed such that the opening sides of the horizontal frame and the vertical frame face outward, and are configured by a large number of partition holes perpendicular to the plane of the horizontal frame and the vertical frame. In addition to enclosing and fixing the four sides of the core board, each compartment hole of the core board was treated with fireproofing and flameproofing by uniformly mixing a boron-based compound into cellulose fiber, which is a natural wood fiber made from waste paper in the form of fibers or cotton. It is filled with fibrous or cotton-like porous wood fiber sound absorbing material. Further, a punched metal having a large number of through holes is bonded to the surface of the core plate, and a fabric skin material such as a woven fabric or a nonwoven fabric is stretched over the surface of the punched metal.

An embodiment of the partition panel of the present invention will be described below with reference to the drawings.

Reference numeral 1 designates a core plate, in which a large number of paper ribbons 1a are bent so as to face the adjacent paper ribbons 1a, and successively adhered to form a large number of partition holes 1 perpendicular to the surface.
b, 1b... Then, connect the letter L to both ends of the letter U, and
The tip of the letter U constitutes horizontal frames 2, 2 and vertical frames 3, 3, each having a cross-sectional shape facing inward of the letter U.
Furthermore, these horizontal frames 2, 2 and vertical frames 3, 3 are installed so that the opening sides thereof face outward, and these horizontal frames 2, 2 and vertical frames 3, 3 form a large number of partition holes 1b perpendicular to the plane. , 1b..., surrounding and fixing the four sides of the upper and lower sides of the core plate 1,
Each of the compartment holes 1b, 1b... is made of a fibrous or cotton-like porous material made of cellulose fiber, which is a natural wood fiber made from waste paper and treated with a flame-retardant treatment by uniformly mixing a boron-based compound. Filled with natural wood fiber sound absorbing material. Further, punching metals 5, 5 having a large number of through holes 5a, 5a, etc. are mounted on the surface of the core plate 1, and a fabric skin material such as woven fabric or non-woven fabric is attached to the surface of the punching metals 5, 5. 6 is stretched, and the through holes 5a of the punched metals 5, 5 are covered with the fabric skin material 6.

In addition, 7 is a cape attached to the upper edge of the spanning board 8 fixed to the upper edge of the upper horizontal frame member 2, and 9 is the lower horizontal frame member 2.
It is a baseboard fixed to the lower edge of the spanboard 10 fixed to the lower edge, and an adjuster star mounting bracket 11 is provided within the width and thickness at a desired position of the baseboard 9, and an adjuster star for height adjustment is provided at the lower end. It is made by fixing a nut 13 which is screwed into a bolt 12.

Reference numeral 14 denotes a support post fixed to the side end of the vertical frame member 3, and in this embodiment, a groove-shaped telephone/electrical wiring cord case is provided in which a resin cap 15 is fitted onto the front and rear surfaces of the protrusion of the support post 14. 16 and a side decorative board 17 made of resin is fixed to the end face. Further, 18 is a Kasagi end cap fixed to the end of the Kasagi 7.

The partition panel configured as described above is used in the same way as a conventional panel.

Next, the sound absorption effect of the above panel will be explained.
The sound waves that have reached the wall surface pass through the fabric skin material 6 and enter the partition holes 1b of the core plate 1 through the through holes 5a of the punched metal 5.

At this time, part of the energy is the vibration of the skin material 6 and the punching metal 5, the vibration of the core plate 1 bonded to the punching metal 5, and the partition hole 1b of the core plate 1.
The sound waves that are absorbed by the friction of the porous wood sound absorbing material 4 housed in the porous wood sound absorbing material 4 and entering the partition holes 1b from the through holes 5a directly vibrate the fibers of the porous wood sound absorbing material 4 to eliminate sound energy. Therefore, it has extremely excellent sound absorption and insulation properties.

Regarding the heat insulation effect, the partition hole 1b of the core plate 1
is filled with porous wood fiber sound absorbing material 4 to prevent air convection between both punching metals 5, 5, and core board 1 and porous wood fiber sound absorbing material 4 are filled with low thermal conductivity material. Because it is constructed with a single layer, it has a high heat insulating effect.

Furthermore, the vertical and horizontal frame members 3 and 2 are constructed with a cross-sectional shape in which an L is connected to both ends of the U-shape, and the tip of the L is directed inward of the U-shape. 2 and the vertical frames 3, 3 are installed so that the opening sides thereof face outward, which not only improves the strength but also is suitable for connecting other mounting members such as caps and baseboards.

As described above, according to the present invention, the panel can be made into a structure with excellent sound absorption and insulation properties as well as excellent heat insulation properties, and is extremely useful for dividing rooms. Since it can use wood fiber material, it has the characteristics of being able to be provided at a low price, and the practical effects after implementation of the present invention are extremely large.
