Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greening structure of a soundproof wall, and more particularly to a new soundproofing wall, an existing soundproofing wall, and a greening structure capable of greening both sides of the soundproofing wall.

[0002]

2. Description of the Related Art Noise countermeasures along railways and arterial roads are extremely important.
Heretofore, as these countermeasures, countermeasures have been taken such as installing a PC board as a soundproof wall between columns erected at predetermined intervals or attaching a sound absorbing material to an existing soundproof wall.

In recent years, attempts have been made to create a natural landscape by actively greening the walls of structures such as soundproof walls in accordance with the recent trend of environmental conservation and natural preference.
The greening of the walls of such structures is considered to become increasingly important in the future.

[0004] In particular, it is considered that the greening of the soundproof wall not only enhances the natural scenery along the railway, but also leads to environmental protection against exhaust gas, and is greatly expected.

As a method of greening a wall surface such as a retaining wall, the present applicant has constructed a greening panel by putting a planting base in a frame frame formed in a shallow box shape, and using the greening panel for a building. We developed a method to attach multiple units to the wall.

In this type of greening method, since the planting base becomes considerably heavy, it is necessary to increase the cross section of the frame material forming the frame frame to some extent to increase the rigidity of the frame frame. However, there was a problem that the frame was exposed until planting was sufficiently overgrown, which was not preferable in terms of aesthetics.

Further, the planting base is fixed by covering it with a net such as a wire net so as not to fall into the frame. As a method for fixing the net, it has been common to fix the net to the frame by screws. Therefore, a lot of time and labor is required to attach the net, and there is a problem that the production of the greening panel becomes very troublesome.

[0008] Further, the applicant has considered using this kind of green panel as a soundproof panel. At this time, a method for mounting the green panel is a predetermined method similar to a normal soundproof panel made of a PC board or the like. For example, a method of attaching to a column erected at intervals by a plurality of brackets using fastening bolts can be considered.

In the case of a soundproof wall constructed along an arterial road or the like, an H-shaped steel is generally used as a support.
Since it is subjected to rust prevention treatment such as hot-dip galvanizing since it is exposed to wind and rain for a long period of time, it is desirable not to damage the rust prevention portion by forming a bolt hole or the like.

[0010] However, since the bracket for mounting the soundproof wall has been conventionally mounted directly on the support or by bolting after drilling the hole, the rustproof portion is damaged and its complete repair is extremely difficult. Thus, there was a major problem regarding weather resistance.

Furthermore, the soundproofing panels are generally arranged between the struts in order from bottom to top, and are fixed to the struts via brackets, respectively. Are fixed to the column at the same position, so that both brackets interfere with each other when the panel is replaced or the like, so that it is extremely difficult to remove only one of the brackets, and there has been a major problem in terms of maintenance.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it has been made possible to very easily and reliably perform greening of a new soundproof wall, an existing soundproof wall, and both surfaces of these soundproof walls. It is an object to provide a greening structure of a soundproof wall.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 of the Invention 1 to 5
Fig. 1 shows an example of a greening structure of a soundproof wall according to the present invention. In the drawing, a plurality of greening is provided between each pillar 1, 1 made of H-shaped steel, which is erected at predetermined intervals along a railway or a main road. The panel 2 is vertically stacked by a plurality of brackets 3 and attached.

An irrigation pipe 4a is laid in the gap between the upper and lower greening panels 2 and 2 in the lateral direction of the greening panel 2,
Further, a water supply pipe 4b for supplying water to the irrigation pipe 4a is laid on the side of each support 1 or several supports 1 respectively.

The greening panel 2 is constituted by inserting a plurality of plant bases 6 into a frame 5 formed in a rectangular box shape that is shallow and elongated horizontally, for example, as shown in FIG.

The frame 5 includes upper and lower horizontal frame members 5a, 5a, left and right vertical frame members 5b, 5b, a plurality of partition frame members 5c, and a bottom plate 5d.
A plurality of partition frame members 5c are mounted between the upper and lower horizontal frame members 5a, 5a at predetermined intervals in the material axis direction of the horizontal frame members 5a, so that the plurality of boxes 7 are partitioned. 7
Is formed in a square shape.

The upper and lower horizontal frame members 5a, the left and right vertical frame members 5b, and the partition frame members 5c are all formed in a thin plate cross-sectional shape in order to reduce the weight as much as possible and to make them inconspicuous. A fitting groove 5e is formed at an upper end portion, and a mounting piece 5f is formed at a lower end portion continuously in the respective material axial directions. Loose holes 5g also serving as water holes are formed in the upper and lower horizontal frame members 5a at predetermined intervals in the material axis direction.

Particularly, both side portions (portion where the fitting groove 5e and the mounting piece 5f are formed) of the loose hole 5g of the upper horizontal frame member 5a are raised, for example, as shown in FIG. The water for irrigation can be stored during the rising, and the loose hole 5g is formed near the bottom plate 5d, so that the entire vegetation base (vermiculite panel) 6 is uniformly and at the bottom of the vegetation base 6. Irrigation can be assured.

The bottom plate 5d also serves to increase the rigidity of the frame frame 5 by supplementing the strength (rigidity) reduction due to insufficient cross section of each frame material. The partitioning frame member 5c is fixed to the mounting piece 5f of the partitioning frame member 5c by screwing as shown in the figure, or by being fitted into a fitting groove formed in each frame member and adhesively fixed.

The upper and lower horizontal frame members 5a, the left and right vertical frame members 5b, and the partition frame members 5c of the frame 5 are all formed as extruded profiles of a lightweight alloy having excellent weather resistance, such as an aluminum alloy.

Also, the bottom plate 5d is a lightweight composite plate having high rigidity,
For example, aluminum composite ceramic tile panels with high rigidity (recycled lightweight composite panels formed from waste materials such as waste glass crushed materials, waste ceramic crushed materials, waste crystal fossil materials, water sedimentation sand, and recycled aluminum or aluminum alloy) It may be formed of a lightweight composite plate, and may be a conventional lightweight aluminum alloy.

The planting base 6 is, for example, a vermiculite panel (artificial soil formed body) processed into a square plate shape and is planted with sedum or the like. The planting base 6 is placed in each box 7 of the frame 5. I have.

Then, a net 8 made of aluminum, stainless steel or resin is put on the frame 5 as a material for preventing the planting base 6 from falling off.
a, each fitting groove 5 of left and right vertical frame member 5b and partition frame member 5c
e is fixed by a beveling member 9 made of resin or molded rubber. At this time, the periphery of the net 8 is
At the same time, it is fitted and fixed in the fitting groove 5e.

As a method of forming the planting base 6, a vermiculite panel is first placed in each box 7 of the frame 5 and then sedum is planted and cured for several weeks, or Sedum or the like may be planted in a vermiculite panel, and after curing for several weeks, put in each box 7.

Here, the vermiculite panel, which has been developed by the present applicant, is formed into a block shape by solidifying with a water-resistant tie material (binder), and has a light density of about 200 to 500 kg / m ^3. It has breathability and water retention that are extremely suitable for growing plants.It does not have the strength of concrete, but has sufficient strength to prevent it from bending, bending, or collapsing when it is carried. is there.

For this reason, a thickness of 50 mm and a size of 300 m
A greening panel can be obtained by planting sedums or the like in a panel processed into an m-square panel.

The greening panel 2 thus formed is vertically stacked between the columns 1, 1, and is fixed to a plurality of brackets 3 and mounting bolts 11 on receiving brackets 10 projecting from the column 1, respectively. ing.

The receiving fitting 10 has two fastening plates 10b each having a hook 10a having a substantially lip-groove cross section on one end side, and is superimposed on each other such that the hooks 10a are located on both sides of the flange 1a of the column 1, respectively. A long mounting plate 10c is superposed on the upper side, and a push bolt 10e is inserted from the front side of the fastening plate 10b into a loose hole 10d formed in communication with these plate materials, and the tip thereof is connected to the inner fastening plate 10b.
It is formed by screwing with a fastening nut 10f welded inside. In particular, the push bolt 10e is eccentrically disposed near the upper end of the fastening plate 10b.

The receiving bracket 10 thus formed is arranged on the side of the flange 1a of the support column 1 with the hooks 10a on both sides engaged with the edges of the flange 1a, and in this state, the push bolt 10e is used. By strongly tightening, the tip of the push bolt 10e and the hooks 10a on both sides are
, And the lower end of the fastening plate 10b is pressed strongly against the flange 1a, whereby the entire metal fitting is formed as shown in FIG.
As shown in FIG.

In this state, since the receiving member 10 is fixed to the column 1, the green panel 2 fixed to the column 1 via the receiving member 10 pushes the hook 10a of the two fastening plates 10b. Since the vertical load P of the greening panel 2 is fixed by changing the vertical load P to the horizontal load P by so-called "leverage action" instead of fixing the flange 1a only with the bolt 10e, each greening panel 2 is fixed. It can be securely fixed to the column 1.

As shown in FIG. 5B, when the push bolt 10e is tightened, the flange 1a
A portion A of the hook 10a and the fastening plate 10b, which closely adheres to the flange 1a, is formed in a rough surface for slip prevention.

The bracket 3 is provided on the receiving plate 1 of the receiving fitting 10.
0c side and a receiving part 3b fixed to the frame 5 side, the fixing part 3a is fixed to the receiving plate 10c by the mounting bolt 11, and the receiving part 3b is fixed.
b is fixed to the mounting piece 5f of the upper or lower horizontal frame member 5a of the frame frame 5.

As a structure for fixing the receiving portion 3b to the mounting piece 5f, the mounting piece 5f and the receiving portion 3b are formed, for example, in a cross-sectional shape which engages with each other as shown in the drawing, and after engaging both, the connection is made. You may connect with the screw 12.

The upper and lower greenery panels 2 are provided with receiving plates 10c.
When the brackets 3 and the mounting bolts 11 are used to fix the brackets 3, the brackets 3 for fixing the upper and lower green panels 2 are preferably fixed at positions shifted from each other in the lateral direction of the frame 5 so that the brackets 3 do not overlap.

At this time, the position of the bracket 3 can be freely set by sliding the bracket 3 in the lateral direction of the frame 5. When the bracket 3 is bolted with the mounting bolts 11 such as a hole-in anchor, the bracket 3 can be slid in the lateral direction of the frame 5 even when the reinforcing bar is in the way, so as to avoid the bar.

Since the upper and lower greening panels 2 are attached to the receiving plate 10c of the receiving fitting 10 in this manner, even when the panels need to be replaced due to falling down or the like, only one panel can be used for the other panel. It can be replaced very easily without disturbing the panel.

In this case, the greening panel 2 is connected to the columns 1, 1
It goes without saying that only the vegetation base (vermiculite panel) 6 in the frame 5 can be exchanged while being attached in between. Reference numeral 13 denotes an existing soundproof panel attached between the columns 1 and 1, and a PC board or the like is used.

FIGS. 6A to 6C show an example in which both sides of the soundproof wall are greened with greening panels. A plurality of greening panels 2 are provided on both sides between the adjacent columns 1 and 1 with the receiving fitting 10 and the bracket 3. And attached by the configuration described above. Embodiment 2 of the Invention FIGS. 7A to 7C show another example of the greening structure of the soundproof wall according to the present invention. In particular, a receiving member 14 is used as a substitute for the receiving member 10 described above.

The receiving member 14 is formed in a substantially lip groove shape in cross section, and has a fixing portion 14a disposed between the flanges 1a, 1a of the column 1, and a plate-like member protruding horizontally on the side of the fixing portion 14a. And the receiving portion 14b.

Loose holes are respectively formed in both side flanges 14c of the fixing portion 14a, and their fastening nuts 14d are welded, respectively, and push bolts 14e are screwed into the fastening nuts 14d from inside to outside.

When the fixing portion 14a is disposed between the flanges 1a, 1a of the column 1, the push bolt 14e is strongly tightened, so that the tip of the push bolt 14e strongly presses the inside of the flange 1a. 12
Are fixed between the flanges 1a of the column 1 respectively.

The greening panel 2 uses a plurality of brackets 3 and mounting bolts 11 and is fixed to the receiving portion 14b by the above-described configuration.

FIGS. 8 (a) to 8 (c) show an example in which both sides of the soundproof wall are constituted by greening panels 2. In this example, the greening panel 2 on the front side and the greening panel on the back side are provided on both sides of the receiving portion 14b. 2 use a plurality of brackets 3 and are attached by the above-described configuration.

[0049]

The present invention has been described above.
It has the following effects. A planting base is attached to a frame formed by upper and lower horizontal frame materials, left and right vertical frame materials, and a plurality of partition frame materials to form a greening panel, and a plurality of the greening panels are provided between columns erected at predetermined intervals. The soundproof wall can be extremely easily greened by arranging it and attaching it to the receiving bracket projecting from the column with a plurality of brackets. At this time, since the bracket is not welded directly to the column, but is attached by a method of strongly sandwiching the column, the surface of the rust-proof column is not damaged. In addition, the greening panels vertically adjacent to each other are attached to the receiving brackets at positions that do not overlap,
When the greening panel is partially replaced, the surrounding greening panels are not in the way, so that any greening panel can be easily replaced and maintenance is easy. Since the upper and lower horizontal frame material, left and right vertical frame material and partition frame material of the frame frame are formed from a lightweight alloy extruded profile, and the bottom plate is formed from a rigid lightweight composite plate, each frame material should be inconspicuous. The design can be enhanced by forming the sheet as thin as possible, and the weight can be reduced. Since the planting base is formed by planting in a vermiculite panel (artificial soil molded body), various sizes can be easily formed in accordance with the thickness and size suitable for the situation of the greening surface.
