Description

  The present invention relates to a sound-absorbing panel, and more specifically, as a panel for an interior of a concert hall, public facility, school, hospital, library, company conference room, or general house, and further, a toilet booth or a partition material. The present invention relates to a sound-absorbing panel that has a good appearance and is excellent in sound-absorbing performance and fire resistance.

  It goes without saying that building construction materials are required to be durable and non-combustible, but interior panels used especially in concert halls, public facilities, schools, hospitals, libraries, company meeting rooms, etc. Furthermore, it is desirable that it has sound absorption performance.

  Conventionally, as a sound absorbing material, a porous board having a large number of sound absorbing holes formed on the surface is generally used. However, many sound absorption holes are made through the surface decorative layer on inorganic boards such as gypsum board and calcium silicate board, which are often used as inner wall panels, or wooden boards such as solid wood and decorative plywood. When there is a hole, there is a limit to the hole diameter that can be formed in these boards, and it is difficult to reduce the diameter to an inconspicuous level.

  Therefore, even if the surface decorative layer is finished nicely by folding printing etc., the bright colored parts such as gypsum board and calcium silicate board will be exposed through each hole and noticeable, so the overall appearance is bad There is a risk of becoming.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on an accompanying drawing. The sound-absorbing panel according to the present invention is formed by fixing a resin decorative film 4 in which pinholes 5 are formed so as to communicate with a ventilation portion of the substrate 1 on a substrate 1 having air permeability. 4 is capable of expressing various patterns such as wood grain patterns and other arbitrary patterns and color patterns, and incombustible, quasi-incombustible or flame retardant in combination with the substrate 1 (and an intermediate material described later). It is characterized by having.

  Since the resin-made decorative film 4 is a surface layer, it is required to have a certain degree of aesthetics as well as being flame retardant. Therefore, the resin decorative film 4 is required to be capable of printing a variety of arbitrary patterns and color patterns such as a wood grain pattern. As this resin-made decorative film 4, for example, a gravure-printable vinyl chloride sheet, on which a film such as a fluorine film is laminated for surface protection and durability improvement, if necessary, is used. be able to. The resin decorative film 4 is required to be able to penetrate a large number of pinholes 5 having an inconspicuous size (as described later, the hole diameter is around 1 mm, preferably 1 mm or less) at regular intervals or randomly. Is done.

  The pinhole 5 formed in the resin decorative film 4 has a hole diameter of about 1 mm, preferably 1 mm or less. When the hole diameter is at this level, ventilation is possible when it is stretched on a wall surface or a ceiling surface. Therefore, the appearance of the resin decorative film 4 printed with a pattern or a color pattern, which is exposed after touching the work, is not impaired.

  The substrate 1 is a base material having non-combustible, semi-incombustible or flame-retardant air permeability, and is composed of, for example, MDF (medium density fiber board), particle board, gypsum board, calcium silicate board, etc. Usually, the thickness is about 1 to 2 cm. The illustrated substrate 1 has large-diameter holes 2 formed at regular intervals (the large-diameter holes 2 may be formed randomly), and the pinhole 5 of the resin decorative film 4 is large. It is transparently arranged in an arrangement corresponding to the arrangement of the diameter holes 2. The resin decorative film 4 is fixed on the substrate 1 such that one or more of the pinholes 5 communicate with the large-diameter hole 2. The pinhole 5 may be provided only at the position corresponding to the large-diameter hole 2 or may be concentrated at the position corresponding to the large-diameter hole 2.

  The large-diameter hole 2 drilled in the substrate 1 is usually a straight circular hole, but the opening on the side communicating with the pinhole 5 may be formed to be narrower than the opening on the opposite side. . In this case, various shapes of the large-diameter hole 2 are conceivable. For example, a large-diameter hole is deeply drilled from one side, and the small-diameter hole is pulled out from the inner bottom to the other side. 3 can be considered (see FIGS. 1 and 7A). In this case, the large-diameter hole 2 may be formed in a conical shape or a pyramid shape (see FIG. 7B), and the large-diameter hole 2 may be formed in a conical shape or a pyramid shape and opened as it is. . Further, the large-diameter hole 2 may be formed in a middle bulge (see FIG. 7C).

  Although one small diameter hole 3 is basically provided for each large diameter hole 2, a plurality of small diameter holes 3 may be provided for one large diameter hole 2 (see FIG. 1). . Further, with the current general technique, it is possible to mechanically form fine holes 3 having a hole diameter (around 1 mm) similar to the pinhole 5 on the surface of the substrate 1 at regular intervals or randomly. Since it is difficult, the small-diameter hole 3 has a slightly larger diameter than the pinhole 5. The resin decorative film 4 is bonded on the substrate 1 provided with the small-diameter holes 3 with the pinholes 5 aligned with the small-diameter holes 3. Needless to say, it is necessary to make the drilling pitches of the pinholes 5 and the small diameter holes 3 correspond to each other. Thus, the sound absorbing panel according to the present invention is configured, and in this state, each pinhole 5 corresponding to each small diameter hole 3 communicates with the large diameter hole 2 via the small diameter hole 3.

  The sound absorbing panel in the embodiment shown in FIGS. 2 and 3 includes an intermediate material interposed between the substrate 1 and the resin decorative film 4 in addition to the substrate 1 and the resin decorative film 4. Is. As the intermediate material, for example, an inorganic or wood-based incombustible board 6 such as a calcium silicate board is used, and when the intercalated board 6 is interposed between the substrate 1 and the resin decorative film 4, A corresponding number of through-holes 7 communicating with the large-diameter hole 2 and the pinhole 5 are formed. The through-hole 7 has the same diameter as the large-diameter hole 2 or a smaller diameter at the position corresponding to the large-diameter hole 2 when the non-combustible board 6 is superposed on the substrate 1, and the same as the pinhole 5. Drilled to have a diameter or larger diameter. In this case, the large-diameter hole 2 is usually a straight circular hole.

  The sound absorbing panel shown in FIGS. 5 and 6 uses a metal thin plate 12 as an intermediate material. A large number of pinholes 13 communicate with the pinholes 5 of the resin decorative film 4 in the metal thin plate 12. It is formed at a pitch corresponding to the pinhole 5 of the resin decorative film 4. The metal thin plate 12 is typically an aluminum thin plate having a thickness of about 1 mm, and the pinhole 13 is formed to have the same diameter as or slightly larger than the pinhole 5 of the resin decorative film 4. In order to form the resin decorative film 4 to have the same diameter as the pinhole 5, the resin decorative film 4 is stretched on the metal thin plate 12, and the resin decorative film 4 and the metal thin plate 12 are perforated at a time. What should I do?

In one embodiment, the substrate 1 is treated to have one or more of a deodorizing function, a humidity control function, a formaldehyde absorption function, a negative ion generation function, and other secondary functions. It is also recommended to use a functional sheet having functions such as odor absorption, CO ₂ adsorption, antibacterial and antifouling as the resin decorative film 4.

  In one embodiment, a non-woven fabric, a woven fabric, a woven fabric, or the like, preferably a non-flammable or flame retardant breathable sheet 8 is attached to the back surface of the base material 1 where the large-diameter holes 2 are opened. The opening of the large-diameter hole 2 is closed (see FIGS. 2, 3, 5, and 6).

  Furthermore, in one embodiment, each large-diameter hole 2 of the substrate 1 is filled with a sound absorbing material 9 such as foamed resin or glass wool. In that case, the sound absorbing material 9, which is an independent piece, may be embedded in the large-diameter hole 2 one by one, but in that case, the work takes time and labor. Therefore, a sound absorbing material sheet 11 in which the sound absorbing material 9 is erected at intervals corresponding to the interval of the large-diameter holes 2 is provided on one base 10, and each sound absorbing material 9 is pressed by pressing it against the back surface of the substrate 1. A method of filling the large-diameter holes 2 is recommended (see FIG. 4).

  According to such a method using the sound-absorbing material sheet 11, the filling work of the sound-absorbing material 9 into each large-diameter hole 2 can be simplified, and the work can be speeded up. The sound-absorbing material sheet 11 can be easily manufactured, for example, by heat-pressing a foamed resin plate using a porous mold. Also in this embodiment, the breathable sheet 8 is stretched as necessary (particularly necessary when the sound absorbing material 9 is an independent piece).

  Furthermore, a four-layer structure (breathability) can be obtained by arranging the three-layer structure of the substrate 1, the non-combustible board 6 (metal thin plate 12) and the resin decorative film 4 on a heat insulating material 14 such as glass wool. If the sheet 8 is included, it may be 5 layers) (see FIGS. 5 and 6).

  The sound absorbing panel according to the present invention formed as described above is used in the same manner as a general inner wall panel, but the surface layer in the case of this sound absorbing panel is provided with a number of inconspicuous pinholes 5. Since it is the resin-made decorative film 4, its appearance is not impaired by the pinhole 5.

  Moreover, since this resin decorative film 4 can express an arbitrary pattern, color pattern, etc., it is possible not only to prepare various types in advance and select them according to the use, but each time Since it is possible to print and use a desired pattern or color pattern, it is suitable for a large variety of small lot construction.

  In this sound-absorbing panel, an intermediate material, in particular, a metal thin plate 12 is arranged under the resin decorative film 4, so that a sufficient surface strength can be obtained, and as a whole, incombustible, semi-incombustible or incombustible. Since it is made of a material, it has a sufficient fire resistance, and further, it can be silenced by absorbing indoor noise and noise through the pinholes 5 and 3 and releasing it into the large-diameter hole 2. Therefore, it exhibits a sufficient sound absorption / silence effect. This silencing effect is further promoted by filling each large-diameter hole 2 with the sound absorbing material 9.

  Further, in one embodiment, a sound absorbing board such as a rock wool sound absorbing board or a porous gypsum board used as a ceiling material or the like is used as it is as the substrate 1, and a non-combustible board 6 or a metal thin plate 12 and a resin are used thereon. The decorative film 4 is stuck. In this embodiment, each of the pinholes 5 does not necessarily correspond to the ventilation portion of the substrate 1, but if a resin decorative film 4 (see FIG. 6) in which the pinholes 5 are formed densely is used, The operational effects are not so different from the case where each pinhole 5 corresponds to the ventilation portion of the substrate 1.

  The sound absorbing board according to the present invention is as described above, and the pinhole 5 formed on the resin decorative film 4 as the surface layer has a hole diameter of around 1 mm, preferably 1 mm or less, and is not noticeable, so it looks good. It can be a sound-absorbing panel with a good surface condition and excellent sound-absorbing performance and fireproof performance, so it can be used for interior hall panels that need to be silenced, especially in concert halls, public facilities, schools, hospitals, libraries, company meeting rooms, etc. Or, it is suitable for use as a toilet booth or a partition material.

  The sound absorbing board according to the present invention may be disposed over the entire construction wall surface, or may be partially disposed such as only the intermediate portion, or the intermediate portion and the upper portion.

  Although the invention has been described in some detail in its most preferred embodiments, it will be apparent that additional embodiments can be made without departing from the spirit and scope of the invention, so that the invention resides in the claims hereinafter appended. It is not limited to that particular embodiment except as limited.
