Description

  The present invention relates to a soundproof plate unit using a light-transmitting soundproof plate and a light-transmitting soundproof wall using the same.

  Noise barriers laid along roads and railways are assembled by dropping soundproof plate units made by attaching metal frames to sound insulation plates into panels between the H-shaped columns arranged in parallel at predetermined intervals. It is done. Of course, sound insulation is required for sound barriers, and there are cases where light transmission is required to reduce driver's feeling of pressure and to secure sunshine to neighboring residents. In the past, the installation location of the soundproof wall was close to the road and residential land, so it was often used as a translucent material made of acrylic or polycarbonate that has high toughness and less concern about scattering due to damage, etc. Attempts have been made to use a glass material having higher visibility as the light-transmitting material.

  As a soundproof plate unit using this type of translucent material, a laminated glass formed by bonding two float glasses through an intermediate film (Patent Document 1), or a metal fiber material is used. The thing (patent document 2) which used the laminated glass using the laid underground glass sheet for the sound-insulating board is proposed.

  However, in the conventional soundproof plate unit using the above-described laminated glass, the translucent soundproof plate is fitted and fixed using a rubber seal material or the like, and therefore, it is necessary to restrain the entire circumference, that is, all four sides. For this reason, a metal frame member inevitably exists also in the upper edge part of the soundproof board unit located in the uppermost stage of a soundproof wall. As a result, the upper edge portion of the soundproof wall that has been made translucent by using a translucent sound insulation board is trimmed with an opaque member. For the purpose of reducing the driver's feeling of pressure, it is desirable that there is no frame member at the upper edge of the soundproof plate unit located at the uppermost stage of the soundproof wall, but the strength of the soundproof plate unit, i.e. The frame member at the upper edge of the soundproof plate unit has been indispensable in order to secure the holding strength and to prevent rainwater and the like from entering the intermediate layer of laminated glass constituting the soundproof plate.

  By the way, about the water resistance of the laminated glass used for a sound insulation board, it is being solved by the technical development in the said field | area (patent document 3). Therefore, it can be said that the problem remaining in omitting the frame member at the upper edge of the soundproof plate unit is only ensuring the holding strength of the soundproof plate by the metal frame.

  The problem to be solved by the present invention is to provide a soundproof plate unit that holds a sound insulating plate with high strength without providing a frame member at the upper edge of the light transmitting sound insulating plate, and a light transmitting soundproof wall using the sound insulating plate unit. It is to provide.

  As shown in FIG. 1, the soundproof plate unit 10 includes a light-transmitting sound insulating plate 20 and a metal frame 30 that surrounds both sides and lower sides of the sound insulating plate 20. The metal frame 30 has a U-shape that is open at the top formed by integrating a pair of vertical frame members 31 and 32 that hold both side portions of the sound insulation plate 20 and a lower frame member 33 that holds the bottom portion of the sound insulation plate 20. It is a frame. Both the vertical frame members 31 and 32 and the lower frame member 33 are integrally formed metal frame members. The height position of the upper side (upper end) of the sound insulating plate 20 and the height positions of the upper ends of the vertical frame members 31 and 32 substantially coincide with each other. As the sound insulating plate 20, for example, a laminated glass using a cross-linked ethylene / vinyl acetate copolymer (EVA) as an intermediate film can be used.

  As shown in FIGS. 2 and 3, the vertical frame members 31, 32 have a U-shaped recess 34 into which the side portion of the sound insulating plate 20 is inserted. The lower frame member 33 has a U-shaped recess 35 into which the lower side portion of the sound insulating plate 20 is inserted. In the recesses 34, 35, a setting block (buffer material) 37 interposed between the bottom surface 36 of the recesses 34, 35 and the end surface 20 a of the sound insulation plate 20, both side surfaces 38, 39 of the recesses 34, 35 and the sound insulation plate A backer (spacer member) 40 is provided so as to be positioned between the two side surfaces 38 and 39. A caulking material 41 is filled between the side surfaces 38 and 39 of the recesses 34 and 35 and the sound insulating plate 20. A rubber plate or the like is used for the setting block 37. For the backer 40, non-crosslinked polyethylene or the like is used. As the caulking material 41, a silicone type, a polyisobutylene type, or the like is used.

  In the soundproof plate unit 10, after the setting block 37 is attached to the bottom surfaces 36 of the recesses 34 and 35 of the metal frame 30, the soundproof plate 20 is inserted into the recesses 34 and 35 of the metal frame 30 from the upper end side of the metal frame 30. The backer 40 is pushed between the side surfaces 38 and 39 of the recesses 34 and 35 and the sound insulation plate 20, and then the caulking material is inserted between the side surfaces 38 and 39 of the recesses 34 and 35 and the sound insulation plate 20. It is generally assembled by filling 41. And the soundproof board unit 10 is completed by attaching the cap 42 to the upper-end opening part of both the vertical frame members 31 and 32. As shown in FIG.

  In the soundproof plate unit 10 configured as described above, the pair of vertical frame members 31 and 32 and the lower frame member 33 constituting the metal frame 30 surrounding both side portions and the bottom portion of the translucent sound insulation plate 20 are provided.
