The present invention relates to a removable sound absorbing panel, and more particularly, a removable sound absorbing panel including a function of detaching and attaching a panel portion to a metal plate on a wall surface by a magnet of a bracket to increase the fixing force of the bracket to the panel portion. It is about.

As is well known, the sound absorbing panel is made of a panel of sound-absorbing and flame-retardant material of glass fiber, and is mainly installed on a wall of a room where noise is generated, such as a gymnasium or a music listening room, and has a function of absorbing indoor sound.

Installation of the sound absorbing panel is usually made in the form of adhesive fixing the sound absorbing panel on the wall. Therefore, the removal and replacement of the sound absorbing panel is not only easy, but also takes a lot of time, in particular, there is a problem in that the economic efficiency of the sound absorbing panel is difficult to recycle.

In this regard, the present applicant is a device capable of attaching and detaching a sound absorbing panel to a wall surface in order to solve the conventional problems as described above, that is, Utility Model Registration Application No. 2004-19309 (2004.07.07) 'Removing and detaching device of sound absorbing panel' Has been proposed.

The sound absorbing and detaching device of the panel forms a plurality of mounting grooves 120 on the rear surface of the panel unit 110 as shown in FIG. 6, has the same shape as the mounting groove 120 and includes a magnet 130a. It is provided with a bracket 130 to be inserted into the mounting groove 120 and fixed by adhesive.

The fixing device of the sound absorbing panel configured as described above has the panel portion 110 attached to the metal plate 140 fixed to the wall by the attachment force of the magnet 130a included in the bracket 130 as shown in FIG. 7. By fixing and forcibly separating the panel unit 110 from the metal plate 140, the sound absorbing panel can be attached to or detached from the wall surface.

However, the fixing device of the sound absorbing panel is because the bracket 130 is adhesively fixed to the mounting groove 120, the fixing force of the bracket 130 to the panel portion 110 is weak, so that the sound absorbing panel is removed from the metal plate 140 of the wall surface. When separating, the bracket 130 is attached to the metal plate 140 of the wall surface as it is, only the panel portion 110 is separated by the bracket 130 from the metal plate 140 again to the mounting groove of the panel portion 110 ( There was a hassle and inconvenience of the work that must be inserted and adhesively fixed to the bracket 130 to 120).

In addition, when the sound absorbing panel is separated from the wall surface, the force is concentrated in the mounting groove 120 of the panel unit 110, causing the panel unit 110 to be damaged, resulting in difficulty in recycling.

In addition, through the gap between the mounting groove 120 and the bracket 130, various external dusts and foreign matter penetrates to cause aesthetic defect, as well as heat transmitted to the sound absorbing panel through the metal plate 140 on the wall. There is a problem that does not provide a means for blocking the life of the sound absorbing panel due to heat.

Accordingly, the present invention has been made to solve the conventional problems as described above, the object of the bracket to the panel portion while including the function of attaching and detaching the panel portion to the metal plate of the wall by the magnet of the bracket The purpose is to increase the holding force.
