Description

  The present invention relates to a sound-absorbing greening panel used for sound absorption and greening by being applied to a slope surface, a building wall, and the like, and a construction method of a construction surface using this panel.

A sound absorbing wall is installed on the side of the railway and road. As shown in Japanese Utility Model Publication No. 55-1208, this sound absorbing wall is a metal box in which a sound absorbing material made of glass wool is housed in a polyethylene bag for rainwater prevention and a sound absorbing window is opened on the noise generating side. Is housed in.
Japanese Utility Model Publication No.55-1208

  A metal box-type sound absorbing wall is designed to drop a box into the opposite groove of an H-shaped support installed along one or both sides of a traffic road, and is intended to absorb sound to the end. No idea has been made to make it easier to crawl up.

  In view of this, the present invention provides a sound absorbing material integrally disposed on the back surface of a climbing aid having a climbing gap on the surface, and a netting material interposed between the climbing aid and the sound absorbing material. An object of the present invention is to provide a sound absorbing greening panel.

  This root shield sheet prevents the aerial roots of greening plants that have climbed the surface of the climbing aid from penetrating the climbing aid and entering the sound absorbing material, where the root is stretched to prevent the sound absorbing function of the sound absorbing material from deteriorating. Is.

  Another object of the present invention is to provide a construction method capable of constructing the sound-absorbing type greening panel on a construction surface such as a slope or a structure with a small number of members and with little effort.

  In the first sound-absorbing greening panel according to the present invention, a net member is disposed on the surface of the climbing aid with a gap. And the sound-absorbing material is arrange | positioned through the root shield sheet in the back surface of this climbing aid.

  A netting material is disposed on the surface of the climbing aid, and when installed on the construction surface, the planting plant grows and climbs the surface of the climbing aid while entwining the vine on the netting material. The aerial roots of this plant invade the climbing aid and try to come out behind it, but there is a root shielding sheet, so it cannot penetrate through it. For this reason, the sound absorbing material does not penetrate into the root of the sound absorbing material, and the sound absorbing material sufficiently exhibits its function and effectively absorbs noise generated by a vehicle or the like. The mesh material may be a three-dimensional solid lattice.

  The second sound absorbing greening panel according to the present invention is obtained by adding a decorative frame to the structure of the first sound absorbing panel. Since this decorative frame covers at least the top end surface of the sound-absorbing greening panel installed on the work surface, rainwater can be prevented from penetrating into the sound-absorbing material, and even if it penetrates, it can be discharged quickly. In addition, since this decorative frame provides a rebirth, even if the vine of the vine grows and extends further from the upper end portion of the sound-absorbing type greening panel, it is prevented. Here, the decorative frame may be installed on a part or all of the lateral surface as necessary.

The sound absorbing material may be a porous sound absorbing material, and may be a polyester fiber aggregate, synthetic rubber, urethane foam, glass wool (glass fiber aggregate), or the like.
These prevent the deterioration of the sound absorption function due to rainwater, and exhibit the sound absorption effect for a long time.

The root shielding sheet is not particularly limited as long as the air roots of the climbing plant do not penetrate, and examples thereof include polyester nonwoven fabrics, polyethylene, polypropylene, vinyl chloride sheets, asphalt sheets, and the like.
According to these, the air roots of the plant climbing up the surface of the climbing aid are blocked by the polyester nonwoven fabric and each sheet and do not enter the sound absorbing material, and therefore the performance of the sound absorbing material is not impaired.

The construction method of the construction surface by the sound-absorbing greening panel according to the present invention attaches a fixing plate by placing an anchor on the construction surface. And the sound absorption type greening panel of Claim 1 or 2 is attached to this fixed plate, and this construction surface is covered.
The sound-absorbing type greening panel is much lighter than the metal box type and is attached to the fixed plate to cover the work surface, so that the number of anchor holes on the work surface is 3.5-4. It can be reduced to about 1.5 / m2 which is less than 0 / m2.

As the object on which the anchor is placed, an appropriate object such as a wall, a steel material, a trunk edge, a lattice, a fence, a slope, a soundproof wall, or the like can be selected.
According to these, the mounting surface of the sound absorbing greening panel is not limited, and there is no need to select a wall body.

The fixing plate includes a base portion and a protrusion protruding from the base portion in the middle of the width direction, the base portion on the surface to be installed, the protrusion in a direction opposite to the surface to be processed, and The head of the bolt is placed on the back side of the ridge, and the shaft portion of the bolt is attached in a state of projecting out of the ridge through a bolt hole drilled in the ridge, and the sound absorbing greening panel is attached to the bolt by the bolt. A space may be formed between the sound-absorbing greening panel and the work surface by attaching to a fixed plate.
If it carries out like this, since all members, such as a sound-absorption type greening panel and a root shield sheet, are fixed with this volt | bolt, there will be few members and it will become simple and the energy of noise can be reduced by space.

A sheath tube may be interposed in the shaft portion of the bolt.
If it carries out like this, in the case of installation of a sound absorption type greening panel, since it can attach without squashing a soft sound-absorbing material, a sound-absorbing effect is not impaired.

The fixing plate may have bolt holes in both sleeve pieces and protrusions on a line forming an angle with the transverse direction.
In this way, even if it hits a reinforcing bar or the like in the wall when the anchor for mounting the fixing plate is placed, it can be constructed without changing the arrangement of the sound-absorbing greening panel by using the adjacent bolt hole made in the fixing plate.

The fixing plate is angled, the base is attached to the work surface by an anchor, the sound-absorbing type greening panel is supported on the supporting part perpendicular to the base, and the supporting part is supported by the detachable retaining angle and holding angle. The space may be formed between the surface of the sound absorbing material and the work surface by the retaining angle.
This simplifies the configuration and allows a large space to be formed between the surface of the sound absorbing material and the work surface, so that it does not enter the sound absorbing material even if rainwater flows along the work surface. However, since it can be discharged from this space, it is possible to prevent the sound absorbing performance of the sound absorbing material from deteriorating.

The dimension of the space may be 10 to 300 mm.
If it carries out like this, since the sound wave which escaped from the sound-absorbing material becomes a complicated flow in this space and loses its energy gradually, it does not propagate outside. In addition, when the work surface has the property of reflecting sound, the sound wave that has passed through the sound absorbing material is repeatedly reflected multiple times in this space, and is efficiently and effectively absorbed by the sound absorbing material and propagates outside. There is nothing.

  According to the first sound-absorbing greening panel according to the present invention, the sound-absorbing material includes a sound-absorbing material, a root-shielding sheet, a climbing aid, and a net-like protective material, and the sound-absorbing material is provided on one surface of the climbing aid. The mesh protective material is disposed on the other surface of the climbing aid with a climbing gap between the other surface and the wall surrounding the place where the noise is generated. By installing the sound-absorbing material toward the surface, the noise can be absorbed and silenced, and a climbing plant can be climbed between the climbing aid and the net-like protective material, and the air root of the climbing plant is a root shield sheet. Therefore, it does not enter the sound absorbing material and impair the sound absorbing performance.

  According to the second sound absorbing greening panel of the present invention, since the decorative frame is provided in addition to the first sound absorbing greening panel, at least the top of the sound absorbing greening panel installed on the work surface by the decorative frame. The end face is covered to prevent rainwater from penetrating into the sound absorbing material, and even if it penetrates, it can be discharged quickly. In addition, since this decorative frame provides a rebirth, even if the vine of the vine grows and extends further from the upper end portion of the sound-absorbing type greening panel, it is prevented.

  According to the construction method of claim 3, since the sound absorbing greening panel is much lighter than the metal box type and is attached to the fixed plate to cover the construction surface, the number of anchor holes for the construction surface Can be reduced to about 1.5 / m 2, which is less than the conventional 3.5 to 4.0 / m 2.

  According to the fourth aspect, since all the members such as the sound-absorbing type greening panel and the root shielding sheet are fixed by the bolts, the number of members is simple and simple.

  According to the fifth aspect, since the sound absorbing material is installed without crushing the soft sound absorbing material, the sound absorbing effect is not impaired.

  According to the sixth aspect, even when the anchor for mounting the fixing plate is placed, even if it hits a reinforcing bar or the like in the wall body, construction can be performed without changing the arrangement of the sound absorption type greening panel by using the adjacent bolt hole drilled in the fixing plate. it can.

  According to claim 7, the fixing plate is an angle, the base is attached to the work surface by an anchor, the sound absorbing greening panel is attached to the support perpendicular to the base, and the retaining angle is detachably attached to the support. Since the space is formed between the surface of the sound absorbing material and the work surface by the holding angle and supported by the holding angle, the configuration is simplified, and a large space is provided between the surface of the sound absorbing material and the work surface. Since it can be formed, even if rainwater flows down along the construction surface, it does not enter the sound absorbing material, and even if it enters, it can be discharged from this space, thereby preventing the sound absorbing performance of the sound absorbing material from deteriorating.

  According to the eighth aspect, since the vertical dimension of the space is 10 to 300 mm, the sound wave that has escaped from the sound absorbing material becomes a complicated flow in the space and gradually loses its energy, so that it does not propagate to the outside.

  FIG. 1 is a perspective view of a specific example of a first sound-absorbing greening panel according to the present invention as seen from above, and FIG. 3 is a front view of a state in which a fixing plate used when a sound-absorbing type greening panel is applied to a work surface is attached, FIG. 4 is a cut-away view of a fixing plate attachment portion, and FIG. 5 is a decorative frame. It is sectional drawing of the uppermost layer part which attached the sound absorption type greening panel with attached to the fixed plate. FIG. 6 is an example of mounting a sound-absorbing greening panel that uses another type of fixing plate.

  The sound absorbing greening panel 1 includes a sound absorbing material 21, a root shielding sheet 22, a climbing aid 23, and a net-like protective material 24. The sound absorbing material 21 is disposed on one surface 25 of the climbing aid 23 via a root shielding sheet 22. A clip, a pin, a string, etc. may be employ | adopted for arrangement | positioning. The net-like protective material 24 is disposed on the other surface 26 of the climbing aid 23 with a climbing gap 27 between the other surface 26.

  This sound-absorbing greening panel 1 is arranged with the mesh-like protective material 24 facing the sound source and the sound-absorbing material 21 facing the work surface P. A net-like protective material 24 is provided on the surface of the climbing aid 23 via a suitable spacing material S such as a clip or a pin. When installed on the construction surface P, the planting plant is attached to this net-like material protective material 24. While climbing the vine, the surface of the climbing aid 23 is grown and climbed. The aerial roots of this plant invade the climbing aid 23 and try to come out behind it, but since there is a root shielding sheet 22, it cannot penetrate this, and it cannot penetrate into the sound absorbing material 21 and stretch its roots. Absent. In addition, the sound absorbing material 21 sufficiently exhibits its function and effectively absorbs noise generated by a vehicle or the like.

  The sound wave that has passed through the root shielding sheet 22 enters the sound absorbing material 21, where energy is absorbed and the function as sound is lost. Therefore, there is no possibility that noise emitted from a vehicle or the like is reflected by the panel 1 and diffused to the surrounding area.

  FIG. 5 is a cross-sectional view of a specific example of the second sound-absorbing greening panel 11 according to the present invention installed on a work surface P. If the decorative frame 31 is removed, the first sound-absorbing greening panel 1 is obtained. Therefore, the description of the installation can be applied to the first sound-absorbing greening panel.

  The sound absorbing action is achieved by the sound absorbing material 21 disposed via the root shielding sheet 22 disposed on the one surface 25 of the climbing aid 23. Clips, pins, strings, etc. can be employed for this arrangement.

  As in the case of the first sound-absorbing greening panel 1, the sound wave that has propagated from the sound source and transmitted through the climbing aid 23 and the root shielding sheet 22 enters the sound-absorbing material 21, where most of the energy is absorbed. Losing the sound function. Therefore, noise emitted from a vehicle or the like is not reflected and diffused by this panel.

  The decorative frame 31 covers at least the top end portion of the sound-absorbing greening panel installed on the construction surface P, and prevents rainwater from penetrating into the sound-absorbing material 21. Even if it penetrates, it can be discharged quickly. Moreover, since this decorative frame 31 is provided with the reverberation part 34, even if the vine of a vine grows and extends further from the upper end part of the sound-absorbing type greening panel, it can be prevented.

The sound absorbing material 21 may be a porous sound absorbing material, such as polyester fiber aggregate, synthetic rubber, urethane foam, glass wool (glass fiber aggregate) and the like.
These are superior in water permeability compared to conventional glass wool, etc., prevent deterioration of the sound absorbing function due to rainwater, and exhibit the sound absorbing effect for a long time.

The root shielding sheet 22 is not particularly limited as long as the climbing plant does not penetrate the air roots, and examples thereof include polyester non-woven cloth, sheets of polyethylene, polypropylene, vinyl chloride, and asphalt sheets.
According to these, the air roots of the plants that have climbed the surface of the climbing aid 23 are blocked by the polyester nonwoven fabric and the respective sheets, and do not enter the sound absorbing material 21, so that the performance of the sound absorbing material 21 may be impaired. Absent.

  The construction method of the construction surface by the sound absorption type greening panel is that an anchor 41 is placed on the construction surface P and the fixing plate 42 is attached. The first or second sound absorbing greening panel 1 or 11 according to the present invention is attached to the fixed plate 42 to cover the work surface P.

As the object on which the anchor 41 is placed, an appropriate object such as a wall, a steel material, a trunk edge, a lattice, a fence, a slope, a soundproof wall, or the like can be selected.
In this case, the mounting surface of the sound absorbing greening panel is not limited, and there is no need to select a wall body.

The fixing plate 42 includes a base portion 43 and a protrusion 44 protruding from the base portion 43 in the middle of the width direction, with the base portion 43 facing the work surface P and the protrusion 44 facing away from the work surface P. In addition, the head 46 of the bolt 45 is placed on the back side of the ridge 44, and the bolt 45 is sound-absorbing in a state where the shaft portion 47 of the bolt 45 protrudes out of the ridge 44 through the bolt hole 48 formed in the ridge 44. Install the greening panel 1.
In this case, since all the members of the sound-absorbing greening panel 1 are fixed by the bolts 45, the number of fixing members is small and simple.
