Description

  The present invention relates to a soundproof panel that is mounted on a temporary fence board used at a construction site or a material storage.

  Conventionally, noise has been generated at construction sites and material depots during foundation work and during material loading and unloading work, and this noise leaks outside the temporary enclosure surrounding the construction site and material depots, and nearby residents and passersby In addition to inconvenience, noise was reflected on the temporary enclosures in the construction site and material storage area, causing discomfort to the workers.

  For example, as shown in FIGS. 9 and 10, a temporary enclosure plate for coping with such noise is provided with a soundproof material S made of a soft vinyl chloride sheet on the back surface of the plate body 31. In this temporary enclosure, both side ends of the plate body 31 are bent to form a side body 32, a plurality of through holes 33 are provided at appropriate positions in the upper part, center part, and lower part of the side body 32, and the side body 32 is further provided. Is bent to form a bent portion 34 (Patent Document 1).

  Since the conventional temporary fence board constructed in this way can prevent the noise generated in the construction site and the material storage area as much as possible by the soundproof material S made of the soft vinyl chloride sheet provided on the back surface of the board body 31, the construction site It is said that noise is less likely to leak outside the temporary enclosure surrounding the material storage area, and the inconvenience to nearby residents and passersby can be reduced as much as possible.

  However, the above-described conventional temporary enclosure has a soundproofing effect that is not sufficient because the thickness of the soundproofing material S made of a soft vinyl chloride sheet is about 1 to 2 mm. There was a problem that it was not possible to sufficiently cope with the use at the construction site.

  Therefore, in order to solve such a problem, as shown in FIGS. 11 to 14, one surface of the honeycomb-shaped panel 43 is pressed against one surface of the panel-like phenol foam 44, and at least a part of the phenol foam 44 is The main body panel 41, which is embedded and embedded in a large number of cells 43a of the honeycomb-shaped panel 43, is inserted from the opening 42a of the bag-shaped synthetic resin cover 42 and stored in the bag-shaped synthetic resin cover 42. A soundproof panel has been proposed (Patent Document 2).

  In the soundproof panel, a panel-like phenol foam 44 is used. This phenol foam 44 is very fragile, so that the main body panel 41 is bent (warped) when being transported or mounted on a temporary enclosure. Then, the exposed portion 44a from the cell 43a of the honeycomb-shaped panel 43 is cracked or cracked. Further, if the bending (warping) of the main body panel 41 is repeatedly performed, the phenol foam 44 may be broken at the end and may fall out of the large number of cells 43 a of the honeycomb-like panel 43.

  For this reason, the soundproof panel is configured such that the metal reinforcing frame 45 is attached to the both side frame portions 43b of the honeycomb-like panel 43 so that the main body panel 41 is not bent (warped).

  Further, as shown in FIG. 14, the soundproof panel is formed by alternately forming the reinforcing frame 45 on the both sides frame portions 43 b of the honeycomb-like panel 43 alternately at the front and rear sides, with the reinforcing frame 45 being a long aluminum alloy flat plate. The reinforcing frame 45 is prevented from dropping off from the both side frame portions 43b of the honeycomb-like panel 43 by being locked between the key-shaped locking pieces 46 thus formed.

  However, in the proposed soundproof panel, the reinforcing frame 45 must be attached to the both side frame portions 43b of the honeycomb-like panel 43. By attaching the reinforcing frame 45, the weight increases or the manufacturing cost increases. It had the problem that.

  Further, since the soundproof panel has to be formed with the hook-like locking pieces 46 on the both side frame portions 43b of the honeycomb-like panel 43 in order to attach the reinforcing frame 45, it takes time to manufacture, and the bag-like When the main body panel 41 is inserted through the opening 42a of the synthetic resin cover 42 and stored in the synthetic resin cover 42, the key-like locking piece 46 is caught by the opening 42a or the like, and the synthetic resin cover There is a problem that it takes time for the storing operation in 42 and there is a concern that the manufacturing cost is further increased.

  Therefore, the present invention aims to solve the above-mentioned conventional problems, and can sufficiently cope with use at a construction site where particularly loud noise is generated, which is accompanied by construction destruction work. The purpose of this invention is to provide a soundproof panel that does not increase, and that can reduce the manufacturing cost.

  Therefore, in the soundproof panel of this invention, the panel-like phenol foam 4 is embedded in a large number of cells 3a of the honeycomb-like panel 3 so that a part of the foam foam 4 is exposed, and exposed above and below the phenol foam 4. It is assumed that a cover 2 is placed on a main body panel 1 in which a plurality of lateral grooves 5 extending in the width direction are arranged in parallel on the portion 4a.

  In the soundproof panel of the present invention, the lateral groove 5 is formed to have a substantially V-shaped cross section.

  In the soundproof panel of the present invention, the lateral grooves 5 are arranged at equal intervals.

  In the soundproof panel of the present invention, the cover 2 is a bag-shaped synthetic resin cover, and the main body panel 1 is inserted through the opening 2a and stored in the bag, and the opening 2a is sealed.

  In the soundproof panel according to the present invention, a gap is formed between the cover 2 and the main body panel 1.

  The soundproof panel of this device has the structure as described above, so if it is used on a temporary enclosure used at a construction site or material yard, a sufficient soundproofing effect will be exhibited, It is possible to sufficiently cope with the use at a construction site where a particularly loud noise is generated, which is accompanied by the destruction work.

  Further, the soundproof panel of the present invention does not require a reinforcing frame, so that the weight can be reduced and the structure of the honeycomb panel is not complicated, so that the manufacturing cost can be reduced.

  In addition, the soundproof panel of this device may be cracked or cracked in the panel-like phenol foam even if it is bent (warped) when transported or attached to a temporary enclosure. In addition, there is no longer any dropping out of the large number of cells of the honeycomb-like panel.

  Hereinafter, embodiments for implementing a soundproof panel of the present invention will be described in detail with reference to the drawings.

  As shown in FIGS. 1 and 2, the soundproof panel of the present invention is such that a main body panel 1 is covered with a cover 2.

  The main body panel 1 is embedded with a panel-like phenol foam 4 in a large number of cells 3a of the honeycomb-like panel 3 so that a part of the foam foam 4 is exposed. A plurality of transverse grooves 5 extending in the width direction are arranged in parallel. The dimensions of the main body panel 1 are not particularly limited, but in the illustrated case, the length is 90 to 110 cm, the width is 38 to 44 cm, and the thickness is 0.5 to 1.5 cm. With such a size, if the two sheets are made into one set, the entire surface of the temporary enclosure used at the construction site or material storage can be easily covered.

  The lateral groove 5 is formed in a substantially V-shaped cross section, and in the dimensions of the main body panel 1 described above, the depth is 0.2 to 0.7 cm as shown in the figure. Seven are arranged in parallel. The lateral grooves 5 can be substantially U-shaped in addition to being substantially V-shaped, and are not limited to being equidistant, and can be arranged at arbitrary intervals.

  In this device, in order to configure the main body panel 1 as described above, as shown in FIG. 6, one side of the honeycomb-like panel 3 is pressed against one side of the panel-like phenol foam 4, and The surface is pressed against the transverse groove mold 6. Then, the phenol foam 4 is embedded in a large number of cells 3a of the honeycomb-like panel 3 so that a part thereof is exposed. A plurality of transverse grooves 5 extending in the width direction are formed in parallel in the exposed portion 4 a of the phenol foam 4 by the transverse groove forming die 6. Thereafter, the lateral groove mold 6 may be removed from the exposed portion 4 a of the phenol foam 4.

  The cover 2 is a waterproof cover made of a synthetic resin or the like, and protects the main body panel 1 from wind and rain when used outdoors. In the illustrated case, the cover 2 is a bag-shaped synthetic resin cover, and the main body panel 1 is inserted through the opening 2a and stored in the bag, and the opening 2a is sealed. The dimensions of the cover 2 are not particularly limited. However, in the case of a bag-shaped synthetic resin cover as shown, the length is 100 to 120 cm and the width is 42 to 48 cm. It is assumed that 1 can be stored with a margin, and a gap is formed between the cover 1 and the cover 2. When noise passes through the gap, the soundproofing effect can be enhanced.

  In this device, the honeycomb-like panel 3 is a panel having a honeycomb-like structure, that is, a panel in which a large number of three-dimensional shapes such as a regular quadrangular prism and a regular triangular prism are arranged without gaps to form a large number of cells 3a. is there. In the illustrated honeycomb-like panel 3, cells 3 a made up of rectangular pillars having a rectangular planar shape are placed in a vertically-long rectangular frame 3 b made up of upper and lower frame portions and both side frame portions that are long flat plates. Many are arranged alternately. As shown in the figure, the honeycomb panel 3 has a length of 90 to 110 cm, a width of 38 to 44 cm, and a thickness of 0.5 to 1.5 cm. With such dimensions, the entire area of the phenol foam 4 described later can be embedded in the cells 3a of the honeycomb panel 3.

  In this device, the phenol foam 4 is obtained by foam-curing a phenol resin and has plasticity. Therefore, when the panel 3 is pressed against the phenol foam 4, it enters the cell 3a of the panel 3 and the phenol foam 4 is buried. In the illustrated case, the phenol foam 4 has a thickness of 70 to 80% entering the cell 3 a of the panel 3. In the illustrated example, the phenol foam 4 has a length of 90 to 110 cm, a width of 35 to 41 cm, and a thickness of 1.5 to 2.0 cm. This phenol foam 4 is known to have thermally and chemically stable properties and excellent sound absorption and heat insulation properties. Therefore, if it is set as such a dimension, even if it uses for the temporary fence board used at a construction site, a material storage place, etc., sufficient soundproofing effect can be exhibited.

  When the soundproof panel of the present invention configured as described above is bent (warped) when the main body panel 1 is bent in the surface direction, as shown in FIG. The V-shape of each horizontal groove 5 is narrowed, and the bending (warping) force is absorbed by the narrowing of these horizontal grooves 5, and as shown in FIG. Even if it bends (warps), the V-shape of each lateral groove 5 expands, and the bending (warping) force is absorbed by the expansion of these lateral grooves 5, and the exposed portion of phenol foam 4 4a will not break or crack.

  Therefore, as described above, the soundproof panel of the present invention exhibits a sufficient soundproofing effect if it is used by being attached to a temporary fence board used at a construction site or a material storage site. It has become possible to cope with the use at the construction site where particularly loud noise is generated, which involves destruction work.

  Further, the soundproof panel of the present invention does not require a reinforcing frame, so that the weight can be reduced and the structure of the honeycomb panel is not complicated, so that the manufacturing cost can be reduced.

  In addition, the soundproof panel of this device may be cracked or cracked in the panel-like phenol foam even if it is bent (warped) when transported or attached to a temporary enclosure. In addition, there is no longer any dropping out of the large number of cells of the honeycomb-like panel.
