Description

  The present invention relates to a sound-absorbing ceiling board suitable for installation in an existing building, and more particularly to a sound-absorbing ceiling board that can be constructed without significantly reducing the height of the ceiling, a method for manufacturing the sound-absorbing ceiling board, and a construction method.

When an acoustical ceiling board is to be attached to an existing building, for example, there is a method shown in FIG.
FIG. 11 is an overall structural view (a) and a partial cross-sectional view (b) viewed from obliquely above, showing an example of a conventional sound absorbing ceiling board construction. In this construction method, a T-bar 101 (cross T-bar 101a and main T-bar 102b) is suspended from a beam or the like of an existing ceiling (not shown) by a wire 100, and the T-bars 101 or the T-bar 101 and the surrounding edge (L lever) 102 are suspended. The sound absorbing panel 103 is dropped into a section surrounded by A section 104 or the like that does not include the sound absorbing panel 103 is a space for installing a lighting fixture, an air conditioner, and the like, and the wire 100 is generally reinforced by a brace 105.

As prior arts employing the above construction method, there can be mentioned the ceiling panel and ceiling panel device of Patent Document 1, and the ceiling sound absorber of Patent Document 2 and its construction method.

JP 2001-227289 A JP-A-5-171731

In the construction method in which the T-bar is suspended and the sound absorbing material is dropped, the length of the wire and the height of the T-bar surely lower the entire ceiling. When the entire ceiling is lowered, the room becomes narrow and difficult to use, and it is inevitable that the user feels a pressure and a negative impression.

An object of the present invention is to provide a sound-absorbing ceiling plate for an existing building that can be mounted in a free arrangement without significantly reducing the height of the ceiling and can sufficiently secure a sound-absorbing function.

In order to solve the above-mentioned problems, a sound absorbing panel for ceiling according to the present invention is a mountain-shaped sound absorbing panel for ceiling in which two sound absorbing plates are bonded to each other with a certain angle, and the two inclined surfaces are horizontal surfaces. In addition, a space portion for ensuring sound absorbing performance is formed on the back surface of the mountain-shaped tip portion.

Moreover, the manufacturing method of the sound-absorbing panel for ceiling of this invention has the following processes, It is characterized by the above-mentioned.
Placing the sound-absorbing plate on a mold having a certain angle of inclination, and obliquely cutting one end thereof to form a mountain shape;
Placing the sound-absorbing plate on a mold having a certain angle of inclination, making a cut on the other end not obliquely cut, and cutting to form a horizontal plane and a vertical plane;
Preparing two sound-absorbing plates created in the above-mentioned two processes, and bonding one end of each of them together;
Polishing the bonded part,
A process of flatly applying a non-combustible nonwoven fabric to the whole and a process of applying a forehead to the forehead.

Furthermore, the construction method of the sound-absorbing panel for ceiling according to the present invention includes the following steps.
A process of drawing the ink line to determine the mounting position of the sound absorbing panel on the existing ceiling,
Installing a parting material for fixing the sound absorbing panel on the ceiling,
A step of sliding the sound absorbing panel and inserting the end portion thereof into a parting material, and a step of fixing with a screw.
It is preferable to attach a double-sided tape to the end portion and insert it into the parting material.

Since the sound-absorbing panel of the present invention can be directly attached to an existing ceiling using a parting material, the reduction in the height of the ceiling can be minimized. In addition, since the space for ensuring sound absorption performance is provided on the back of the mountain-shaped tip, a triangular space is created between the sound absorption panel and the ceiling after construction, and this space exhibits sound absorption performance. be able to.
Furthermore, since the sound absorbing panel of the present application has a mountain shape formed by abutting two sound absorbing plates, the sound absorbing panel can be bent and fitted, which is particularly effective when the last one is constructed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the sound absorbing panel 1 for ceiling is obtained by joining two sound absorbing plates with an angle and bonding them in a mountain shape, and the two inclined surfaces 2, 2 are horizontal surfaces 3, 3 and a vertical surface. There are end portions 5 and 5 formed by the surfaces 4 and 4, and a space portion 7 for ensuring sound absorption performance is formed on the back surface of the mountain-shaped tip portion 6.

In order to manufacture the sound absorbing panel 1 for ceiling, first, a sound absorbing board made of glass wool or the like is prepared and cut into a predetermined dimension. For example, an even number of 450 × 250 mm or 600 × 250 mm sound absorbing plates w are created.

Next, as shown in FIG. 2, the sound absorbing plate w is placed on a mold 10 inclined at an angle θ1, and one end 8 thereof is obliquely cut (indicated by a C1 line) for forming a mountain shape. Further, as shown in FIG. 3, the sound absorbing plate w is placed on the inclined mold 11 with an angle θ2, and the other end 12 is cut (C2 line) and cut (C3 line), and the sound absorbing panel for ceiling is used. A shape to be a horizontal plane 3, 3 and a vertical plane 4, 4 is created.

When the two sound absorbing plates w crafted as described above are prepared and the ends 8 are abutted and bonded together, the shape shown in FIG. 1 is completed. The butt-bonded portion is polished with sandpaper or the like in order to scrape and smooth the protruding adhesive or glass wool fiber. Thereafter, a non-combustible non-woven fabric such as glass paper is flattened on the entire surface, and the forehead 9 is further framed and finished to finish the product. In the sound absorbing panel 1 thus completed, for example, the thickness of the end portion 5 is 5 mm, the length is 450 mm or 600 mm, and the width of the fore edge portion 9 is 445 mm.

An example of attaching the sound absorbing panel for ceiling 1 of the present invention to an existing ceiling will be described below. As shown in FIG. 4, a marking line 13 is drawn on the existing ceiling to determine the mounting position of the sound absorbing panel 1. At this time, the installation position is determined avoiding the illumination 14, the fire alarm, the air conditioner, and the like.

Next, the parting material 15 is attached as shown in FIG. The parting material 15 is a jig for fixing the sound absorbing panel 1 to the existing ceiling. As shown in detail in FIG. 6, the parting material 15 is a U-shaped rod-shaped member formed of plastic such as vinyl chloride resin.

Next, as shown in FIG. As an attachment method, the sound absorbing panel 1 is slid and the end portions 5 and 5 are inserted into the parting material 15. At this time, it is preferable to attach a double-sided tape to the end portions 5 and 5 and insert it into the parting material 15 in order to prevent displacement. Thereafter, even if the sound absorbing panel 1 made of fragile glass wool is fixed by screws, it can be securely attached.

The ceiling sound-absorbing panel 1 of the present invention is easy to mount the parting material 15 and has a high degree of freedom, and therefore can be arranged in various ways as well as in a straight and parallel construction as shown in FIG. 8-10 is a top view which shows the example of arrangement | positioning of the sound-absorbing panel for ceilings of this invention. FIG. 8 shows an example in which sound absorbing panels 1 are spaced apart from each other, FIG. 9 shows an example in which two color sound absorbing panels 1 are arranged in a chess pattern, and FIG. 10 shows an example in which long sound absorbing panels 1 are arranged alternately. It is.

The sound-absorbing panel for ceiling according to the present invention can be mounted in a flexible arrangement by simply attaching a parting material to an existing ceiling without reducing the height of the ceiling so much. Therefore, it can be installed in any existing building such as a general household, a factory, a warehouse, or a store.
