Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to an improved soundproof panel, and more particularly, to soundproofing at various construction sites where noise is generated, such as construction work and civil engineering work, or in various factories where noise sources are housed. The present invention relates to the improvement of a soundproof panel which is used as a fence or a soundproof building, which is easily assembled and used as a fence or building at the site of use.

[Prior art]

 Conventionally, this type of soundproof panel has an appropriate sound absorbing material built in part or all of the inner space of the main body made of a thin box made of steel, etc., and the main body has a smooth surface and a back surface. A large number of small openings for providing a sound absorbing effect are provided in the sound absorbing material incorporated in the main body. When such a soundproof panel is used as a fence or the like outdoors, for example, rainwater may infiltrate through the large number of small holes on the surface of the soundproof panel where the small holes are provided, In addition, there are many cases where the small holes are clogged with mud or the like. On the other hand, when the soundproof panel is used as a soundproof house in various factories where noise sources are housed, the oil used in the factory is filled with many small openings on the back of the soundproof panel. Occasionally, a clogging condition was caused by adhesion to holes. Therefore, if rainwater enters through the small openings of the soundproof panel or mud or oil adheres to the small openings, the small openings become clogged. This adversely affects the sound absorbing effect of the sound absorbing material built into the car, which reduces the sound absorbing function, which has been a fatal problem of this type of soundproof panel. However, conventionally, there has been no effective means for solving the above problem.

[Problems to be solved by the device]

 The present invention was developed in view of the above-mentioned conventional circumstances, and an object thereof is to solve the above-mentioned conventional problems and to provide the soundproof panel provided on one surface of the soundproof panel. In addition, a soundproof panel that can always exhibit the best sound absorbing function without rainwater entering through the large number of small openings and clogging of the large number of small openings due to mud, etc. To provide.

[Means for Solving the Problems]

 The soundproof panel improved according to claim 1 is a soundproof fence or a soundproof fence at the site of various construction works that generate noise, civil engineering works, etc., or in various factories in which equipments that generate noise are stored. A soundproof panel that forms a soundproof building and is easily assembled and used as a fence or a building at the site of use, and is suitable for a part or all of the inner space of the main body made of a thin box shape such as steel. In addition to incorporating a sound-absorbing material, the main body has a smooth front surface, and the back surface is provided with a large number of small holes for absorbing the sound-absorbing effect of the sound-absorbing material incorporated in the main body. A protective film layer made of a washable material having no water absorption is disposed on the back surface having small openings. In the soundproof panel with the improvement described in claim 2, the protective film layer according to claim 1 is arranged in a peelable and replaceable state.

[Action]

 According to the soundproof panel according to any one of claims 1 and 2, since a protective film layer made of a washable material having no water absorbing property is disposed on the back surface of the soundproof panel, a large number of small holes are formed on the back surface of the soundproof panel. Rainwater does not infiltrate through the small openings, and if the small openings are clogged due to mud or oil adhering to the large openings, the protective film layer can be easily washed. Alternatively, since the protective film layer can be replaced and re-attached at appropriate times, the sound absorbing effect can always be optimally exhibited.

【Example】

 Embodiments of a soundproof panel improved according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a soundproof panel 1 of this embodiment. The soundproof panel 1 forms a soundproof fence or a soundproof building in various construction sites that generate noise, such as construction work and civil engineering work, or in various factories where equipments that generate noise are stored. A soundproof panel that is easily assembled and used as a fence or a building at a use site, and is made of glass wool material, rock wool material, or cotton in a part or all of the inner space of the main body 2 formed of a thin box shape such as steel. A sound absorbing material (not shown) made of a material or the like should be built in, the front surface 3 of the main body 2 should be a smooth surface, and the back surface 4 should make the sound absorbing material built in the main body 2 exhibit a sound absorbing action. A large number of small openings 5 are provided, and a protective film layer 6 made of a washable material having no water absorption is disposed on the back surface 4 having the large number of small openings 5. In addition, in this embodiment, the small opening 5 has an opening shape as shown in the drawing, but the opening shape of the small opening 5 in the present invention includes, for example, a small circle. Of course, any aperture shape may be used. The protective film layer 6 is formed of a vinyl chloride resin material, a polyethylene material, or the like, and the protective film layer 6 is thin so as not to adversely affect the sound absorbing function of the sound absorbing material built in the main body 2 of the soundproof panel 1. Things are convenient. In this embodiment, the protective film layer 6 is arranged so as to be peelable and replaceable while being pressed from the upper surface by the pressing tool 8. In addition, in FIG. 1, reference numeral 7 is a joint portion when a plurality of the soundproof panels 1 are connected and used. According to the soundproof panel 1 thus configured, since the protective film layer 6 made of a washable material having no water absorption property is disposed on the back surface 4 of the soundproof panel 1, a large number of the back surface 4 of the soundproof panel 1 is provided. If rainwater does not enter from each of the small openings 5, and if the small openings 5 are clogged due to mud or oil adhering to the many small openings 5, Since the protective film layer 6 can be easily washed or the protective film layer 6 can be exchanged and re-attached at appropriate times, the sound absorbing action can always be optimally exhibited. The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention. For example, in the present embodiment, the soundproof panel 1 having the illustrated form is used, but the present invention can be applied to any form of soundproof panel.

[Effect of device]

 According to the soundproof panel 1 of the present invention described in detail above, rainwater may enter through a large number of small holes 5 provided on one surface of the soundproof panel 1 that has been subjected to soundproofing, or the large number of the large number of small holes 5 may be provided. It is possible to provide a soundproof panel that can always exhibit the best sound absorbing action without causing clogging of the small openings 5 due to mud or the like.
