BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof wall net mounting jig for preventing the fall of green plants such as ivy vegetated on the wall surface of the soundproof wall.

[0002]

2. Description of the Related Art Currently, pillars are provided on a roadside portion of a highway, a railroad, or the like at a certain distance, and sound-insulating or sound-absorbing soundproof panels are installed between these pillars to construct a soundproof wall to reduce noise. It is known to avoid pollution. In addition, recently, it has been proposed to crawl greenery plants such as vines on the walls of soundproof walls to improve the landscape and promote soundproofing.

[0003]

[Problems to be solved by the present invention] The conventional soundproof wall described above has the following problems. <B> If measures are not taken to prevent the fall of the green plants, the green plants may easily peel off from the wall of the soundproof wall and fall onto the road due to an increase in the weight of the green plants or strong wind. If green plants fall into the area, the safety of driving is threatened and it is very dangerous. <B> As a method to prevent the fall of green plants,
It is conceivable to make a hole in the pillar or weld it to attach a net material such as a wire mesh covering the surface of the soundproof wall. However, in order to drill or weld existing columns,
It takes a lot of time and effort. In addition, some existing columns have zinc plating on the surface for the purpose of anticorrosion. When this type of support is perforated or welded, the strength of the support is reduced and there is concern about corrosion.

[0004]

[Purpose of the Invention] The present invention has been made in order to solve the above problems. The purpose of the present invention is to make a mesh on the surface of an existing soundproof wall by a simple work without lowering the strength of the column. It is to provide a jig for attaching a net for a soundproof wall to which a material can be attached.

[0005]

[Means for Solving the Problems] That is, the present invention is a jig for attaching a net to the surface of an existing soundproof wall formed by dropping a plurality of panels between columns that are erected at regular intervals. A seating portion that is in contact with the flange surface of the column, and an overhanging portion that extends in a direction perpendicular to one end of the seating portion.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described below with reference to the drawings.

<B> Overall configuration FIG. 1 is a plan view showing a net 3 such as a wire mesh attached to the side surface of the soundproof wall 4 using the attachment jig 1 and the rope member 2 of the present invention, and FIG. The figure is shown. The soundproof wall 4 includes a pillar 41 having an H-shaped cross section, which is erected at a constant distance, and the pillars 41, 41.
It is composed of a plurality of panels 42 that are interleaved to form a continuous wall. The panel 42 includes a sound absorbing panel made of aluminum in addition to a sound insulating panel made of concrete. Each panel 42 is fitted in the groove of the support column 41 with some clearance. Further, a green plant 5 such as an ivy is vegetated on one surface of the soundproof wall 4, and the vegetation plant 5 grows along the wall surface of the soundproof wall 4. The structure relating to the above soundproof wall 4 and the point that the greening plants 5 are vegetated on the surface of the soundproof wall 4 are the same as the conventional one.

<B> Net mounting structure In the present invention, a pair of mounting jigs 1 as shown in FIGS.
Attach the net 3 along the side surface of. The mounting jig 1 is formed by bending a belt-like body into an L-shape and forming a seating portion 11 on one side.
While forming the overhanging portion 12 on the other side, the striker portion 13 is integrally formed at the end portion of the seat portion 11 in a direction orthogonal to the seat portion 11, and further at the end of the strike portion 13 in parallel with the seat portion 11. The insertion portion 14 is formed integrally. The plate surface of the projecting portion 12 Yes by opening a plurality of openings 15, apertures 15a close to the seat portion 1 1 is used as the insertion hole of the bolt 7, the overhang portion 12
The open hole 15b on the free end side is used as an insertion hole for the rope material 2. The shape of the receiving unit 13 is to expand the receiving area.
From the seating portion 11 to the side of the overhanging portion 12 to project the hammer.
It is formed so that it can be easily hit with a tape . The gap between the seating portion 11 and the insertion portion 14 is designed to be substantially equal to the thickness of the flange 43 of the support column 41, and the tip of the insertion portion 14 is easily inserted between the flange 43 and the panel 42. Sharp difference
It has a recessed surface .

[0009]

Next, a method of attaching the net 3 to one surface of the existing soundproof wall 4 will be described.

<A> Mounting of mounting jig As shown in FIG. 3, the flange 43 of the support column 41 and the panel 42 are mounted.
In between, the tip of the insertion portion 14 of the mounting jig 1 is lightly pressed and the striker portion 13 is lightly hit with a hammer or the like. Generally, the panel 42 has some rattling with respect to the flange 43.
This is because a mounting error of a mounting tool (not shown) for fixing the panel 42 to the support column 41 and a manufacturing tolerance of the panel 42 are taken into consideration, and a gap of about 5 mm is actually expected.
A sharp insertion surface is formed at the tip of the insertion portion 14 of the mounting jig 1.
Therefore, the insertion portion 14 easily enters between the panel 42 and the flange 43 by the impact, and as a result, the insertion portion 14 and the seating portion 11 cooperate to clamp the flange 43. Similarly, the mounting jig 1 is also inserted into the other flange 43 side, and the projecting portions 12 and 12 of both mounting jigs 1 and 1 are fastened with bolts 7. According to the above procedure, the pair of mounting jigs 1 and 1 are mounted at regular intervals along the vertical direction of each column 41.

<B> Attachment of Rope Material Next, as shown in FIGS. 1 and 2, the rope material 2 is stretched so as to connect the respective attachment jigs 1 in the horizontal direction. More preferably, every other rope material 2 is attached, and the net 3 described later is used.
After the installation process of, the remaining rope material 2 on the surface side of the net 3
It is desirable to attach. Further, the end of each rope member 2 may be fixed to the attachment jig 1, but may be fixed to the support column 41 or another member by using another device.

<C> Attachment of Net Next, the net 3 is developed on one surface of the soundproof wall 4, and the intersection of the rope 2 and the net 3 is fixed by using a binding wire or the like. If the upper side of the net 3 is fixed to the rope material 2 in advance, the work of attaching the net 3 can be performed smoothly.

<D> Growth of Green Plants As shown in FIG. 2, a net 3 is stretched outside the green plant 5 vegetated on the side of the existing soundproof wall 4, so that the green plant 5 is sound-proofed. When the wall 3 is peeled off and dropped, the net 3 receives the green plant 5. When the green plant 5 is small, the net 3 functions as a growth base that replaces the soundproof wall 4.

[0014]

[Other Modifications] In the above embodiment, a pair of mounting jigs 1 and 1 is used.
Although the case where the entire lengths of the overhanging portions 12 are formed to be equal to each other has been described, one of the protruding portions 12 may be formed to be short and the rope material 2 may be supported only by one mounting jig 1. Further, the attachment jig 1 may be configured by adding a reinforcing material that obliquely connects the seating portion 11 and the overhanging portion 12.

[0015]
