DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a soundproofing device which is installed above a soundproofing wall and used for reducing noise generated on roads, railways, factories and the like.

[0002]

2. Description of the Related Art The structure of a soundproof wall is, for example, H
It is a common practice to construct a column using steel or the like and install panels in such a way that the column is dropped between the columns or fixed with bolts of the column.

[0003]

However, the intervals between the columns are not always equal and vary in many cases due to construction problems such as local terrain. Generally, the soundproofing device mounted on the upper part of the soundproof wall is fixedly mounted on a support. However, if the spacing between the supports varies, there is a problem that the length of the soundproofing device cannot be unified. That is, forming a soundproofing device having a different length for each column interval leads to a significant increase in cost. In addition, in the case of a type in which a rail-shaped thing is installed and the soundproofing device main body is placed on it, the spacing between the fixing holes is not constant, so equipment such as drilling on site is necessary, This leads to an increase in construction costs.

[0004] In view of the above-mentioned circumstances, the present invention can minimize the cost increase due to the variation in the column spacing, and can easily and safely mount the soundproofing device. It is an object of the present invention to provide a mounting structure for a soundproofing device.

[0005]

That is, the present invention is a mounting structure of a soundproofing device in which a rail is laid along the soundproofing wall above the soundproofing wall and the soundproofing device is mounted on the rail. In order to insert a screwing means such as a bolt or a nut into one of the rails or the soundproofing device laid along along with the shaft being restricted from rotating in the axial direction, and to be able to move along the longitudinal direction. A gutter-shaped groove is provided, and a hole for screwing a screwing means such as the inserted bolt or nut is provided on either the rail side or the soundproofing device side, and a screw such as the bolt or nut is provided. Each soundproofing device side is fixed to the rail side by screwing to the connecting means with a screwing means such as a nut or a bolt.

[0006]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a mounting structure of a soundproofing device according to the present invention. The soundproofing device (fixes a panel P constituting a soundproof wall).

Is done. Prior to the on-site mounting work, the mounting member 11 and the auxiliary member 12
May be assembled together.

The rail 2 of this embodiment shown in FIG. 2 is of a long shape (having a length between the columns) having a substantially U-shaped cross section (or a length between the columns). It is configured to be covered by the short fixing member 30. The rail 2 is formed in various lengths and shapes (corresponding to the interval between the H steels 1) according to a place where the rail 2 is installed, and the side edge of the upright wall 21 on one side is connected to the side edge of the fixing member 30. An engagement protrusion 22 is formed for engagement, and the other
3, an elliptical hole (or a perfect circular round hole) 23A is formed at a plurality of locations over substantially the entire length direction.

On the other hand, the fixing member 30 has a folded groove 31 into which the engaging projection 22 is fitted. The fixing member 30 is formed with a downwardly hanging wall 33 that is screwed to the upright wall 23. The wall 33 has a long hole 33 </ b> A and a gutter-like groove 34 formed in the longitudinal direction. Are formed. Further, a square (or hexagonal) nut (not shown) is inserted into the groove 34 of this embodiment so as not to rotate in the rotation direction, and can be freely moved in the length direction. . For example, in the case of a square nut, the upper surface and the lower surface of the four side surfaces exhibiting a square shape are inserted in a state in which the upper surface and the lower surface are in close contact with the ceiling surface and the floor surface in the groove 34, whereby the nut is prevented from rotating and turned. It cannot move (it can slide freely in the length direction in the groove). Further, by attaching a blind plate 35 (see FIG. 1) to the other side edge of the fixing member 30, the bolts and the like can be hidden from the exposed state, and the external appearance can be improved. . The fixing member 30 is formed by extrusion molding of, for example, aluminum or the like, and is formed to have a length L excluding the notch 3B so that the soundproofing device main bodies 3 described later can partially overlap each other. .

The fixing member 30 of this embodiment has a screw hole 36 for fixing the soundproofing device main body 3 with a bolt or the like.
Are formed. Further, instead of inserting the nut into the groove 34 of this embodiment, a square (or hexagonal) bolt may be inserted in the same state. Further, the fixing member 3
0 has an engagement projection 37 for easily positioning the soundproofing device main body 3 and preventing the soundproofing device main body 3 from shifting and moving.

As shown in FIG. 3, the soundproofing apparatus main body 3 is formed so that an open end side (hereinafter, an open end) is wider than a closed end (hereinafter, a closed end). As shown in (1), the end portions of the opening are partially overlapped with each other so that they can be connected very easily and continuously.
The soundproofing device main body 3 is made of a relatively thin material (in this embodiment, an appropriate resin such as polycarbonate, polypropylene, ABS resin, AES resin, M-PPO).
(Modified polyphenylene ether), M-PPE, etc.), and can be applied to a soundproof wall portion having a curved shape as shown in FIG. A groove 3A is formed on the lower surface of the soundproofing device main body 3 of this embodiment so as to engage with the engaging projection 37 of the fixing member 30. In order to prevent the occurrence of the noise, the lower portion on the closed end side has a structure in which a cutout portion 3 </ b> B which is missing only in the overlapping portion with the adjacent soundproofing device main body 3 is provided. In this embodiment, the groove is provided on the soundproofing device side, but the groove may be provided on the rail side.

Therefore, according to this embodiment, even if the rail 2 provided to be fixed to the H steel 1 serving as a column has various lengths that are significantly different from each other or has a curved shape, that is, various types of rails can be used. Even if the fixing member 30 has the same shape, a plurality of fixing members 30 having a fixed length and the same shape are prepared, and the fixing members 30 are slid on the rail 2 irrespective of the interval between the H steels 1 and joined one after another and continuously attached without gaps. be able to.

When fixing each soundproofing device main body 3 to these fixing members 30, the position of the soundproofing device main body 3 is adjusted in accordance with the screw holes 36, and the bolts are tightened with bolts. Easy installation without any need. As described above, according to this embodiment, the rail 2 is fixed at two front and rear positions for each H steel 1, and the projection 22 of the fixed rail 2 and the groove 31 of the fixing member 30 are engaged, and After the nuts in the grooves 34 and the bolts and screws passing through the holes 23A are screwed, the central portion of each soundproofing device main body 3 is simply tightened to the fixing member 30 with a bolt, and the soundproofing devices are attached to the columns. Can be stopped. Therefore, for example, even in an installation work such as a viaduct, one side of the soundproof wall,
That is, since the installation work of the soundproofing device can be performed only by the work from the road side, it is possible to prevent a large increase in cost due to the installation of a high scaffold required when performing the work from both sides, and it is also possible to prevent a dangerous height. Work can be avoided and safety can be improved.

The square (or hexagonal) nut inserted into the fixing member 30 can move freely in the groove.
When used in a place where the rail 2 is installed in an inclined state, for example, as shown in FIG. 6 (N is a nut, S is a screw with a slit), it is temporarily fixed with an appropriate adhesive or the like. As shown in FIG. 7, screwing is performed by using a slit portion, and the distal end surface of the screw S is pressed strongly against the inner wall surface inside the groove, and the base end surface of the nut is pressed against the near inner wall surface of the fixing member 30. It may be fixed in a state of being sandwiched and temporarily fixed. In this case, if a material having a difference in hardness, such as a screw made of iron and a groove portion made of aluminum, is used, a temporary fixing can be made firmly, so that an adhesive is unnecessary. In addition, when the final fixing is performed after the temporary fixing, the screw S
Screw another nut onto the proximal end of the screw and securely tighten and fix these two nuts on both sides of the screw.

In this embodiment, a long rail 2
In addition, a short fixing member 30 having the same length as the soundproofing device main body 3 is provided, and the soundproofing device main body 3 is mounted on the fixing member 30. For example, as shown in FIG. After the rail 2 'is attached to the H steel 1 first, the soundproofing device main body 3' may be directly attached to the rail 2 'without the fixing member 30 interposed therebetween. In this embodiment, a groove 21 ′ (a nut N is prevented from being inserted and inserted) and an elongated hole 22 ′ and a fitting groove 23 ′ are formed in the rail 2 ′. , This rail 2
′ Is fixed between the H steels 1 with bolts or the like.
