2. Description of the Related Art In many cases, a partition panel is used to partition a large space. There are various forms of the partition panel, but the most common panel is a steel surface material on both sides of a core material such as a paper core. Are bonded together. If this panel is installed without any gap, it is possible to block noise to some extent. On the other hand, the partition system is not limited to such a fixed panel type, but may be configured so that a panel can be suspended and moved on a ceiling rail.

[0003] This type of moving panel (moving wall) is arranged at a predetermined position, and is provided with a joint rubber at a side end so that no gap is left between the moving panels. In order to obtain such sound insulation, it is first to prevent a gap from remaining in the partition, but in order to cut off a very loud noise, for example, a sound generated from a press machine or the like, simply It is not enough to arrange and partition panels so that there are no gaps. That is, sound is transmitted to the opposite side by vibrating the panel main body, and it is necessary to have a panel structure capable of blocking this sound wave.

[0004]

As described above, if the panel of the conventional type is installed so that no gap is left between the panels, a certain degree of sound insulation can be obtained, but very loud noise cannot be cut off. . The problem to be solved by the present invention is this problem. For example, the present invention provides a panel for forming a partition for blocking noise generated from a press machine or the like.

[0005]

The sound insulation panel of the present invention comprises a gypsum board as a backing material and a steel surface material adhered to one surface of the gypsum board, which is well known as a conventional panel form. In the present invention, a sound absorbing material is attached to the opposite surface of the gypsum board. Here, the type of the sound absorbing material is not particularly limited, but glass wool is generally used. The sound absorbing material is fitted on the frame attached to the back side of the panel and overlaps the gypsum board. As a result, the sound absorbing material is largely exposed on the back surface of the panel and covers the back surface.

The surface material adhered to the gypsum board is slightly larger, and an airtight material is provided along both sides of the rear surface and on the upper and lower sides. The sound insulation panel of the present invention is to be installed by being screwed to a vertically standing stud (post), but at this time, a gap is not formed between the stud surface and the stud is hung between the studs. The airtight material comes into contact with the horizontal rail so that no gap remains. Further, fastening portions for fixing to the stud surface are formed on both side ends of the surface material.

Here, the installation form of the panel of the present invention, that is, the partition form is free, and it can be configured as a conventional linear partition or a partition that surrounds the periphery like a booth. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
