Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a soundproof wall used at work sites where noise is generated.

(Prior art) At work sites where noise is generated, such as maintenance and maintenance sites for railway lines, road construction sites, and construction and demolition sites of buildings, etc., noise pollution is caused by the work to local residents. Soundproof walls are placed around the entire work site or around equipment such as compressors that generate noise.

Conventional soundproof walls are made of styrofoam, glass wool, etc. in the form of panels, and their installation methods are as follows:
A frame is erected around the work site or equipment that is a source of noise, the soundproof wall is fitted into the frame without any gaps, and then the soundproof walls are connected together using bolts, nuts, etc. They were connected using connecting fittings such as reinforcing metal fittings.

(Problems to be solved by the present invention) Therefore, with conventional panel-shaped soundproof walls, not only is it time-consuming to install, but the soundproof walls are fixed, so it is also time-consuming to dismantle and remove them. Hanging,
Moreover, since the soundproof wall is large, it is difficult to store it.
There are problems such as difficulty in transportation.

(Purpose of the present invention) Therefore, the present invention was made in view of the above-mentioned conventional problems, and provides a soundproof wall that can be easily installed and dismantled at work sites, etc., and is easy to store and transport. The purpose is to

(Means for Achieving the Object) For this purpose, in the present invention, the soundproof wall is provided with bag-shaped storage portions for storing soundproofing material on the front and back surfaces of the sheet, and the storage portions are arranged in parallel. A width corresponding to the width and board thickness of the soundproofing material is attached to the front or back surface of the sheet, and when the soundproofing material is enclosed in the storage part, the sheet is alternately bent so that the end surfaces of the soundproofing materials are close to each other. The soundproofing material is arranged in a straight line to form a continuous soundproofing wall surface, and one side edge of the folded portion of the sheet has a hinge function that can be folded alternately, and
A locking device for locking the attached portion is attached to at least one end of the sheet in the folding direction or width direction, and adjacent ends of the sheet on both sides in the width direction or folding direction on the side where the locking device is not attached are attached. In addition, an overlapping portion having a locking member for connecting to another sheet is formed, and a soundproof material made of styrofoam, glass wool, or the like is enclosed in the storage portion.

(Function) With this configuration, it is sufficient to simply lock the locking tool attached to one end of the sheet in the folding direction, that is, in the length direction, to the sound source body or to the curing frame, scaffolding frame, etc. at the work site. Further, the soundproof walls can be connected without gaps by overlapping the overlapping portions of adjacent sheets and connecting them with connectors such as hooks, resin fasteners, etc.

In addition, storage sections for storing soundproofing materials are arranged in alternating rows in the seats, and the storage sections are filled with soundproofing materials to make them foldable, so the soundproofing wall can be folded into a compact form when stored or transported. be able to.

(Example) The present invention will be described below with reference to an illustrative example.

A is a foldable soundproof wall, and is composed of a sheet a made of thick cloth and a plurality of soundproof materials b enclosed in a storage section 11 formed in the sheet a.

The storage portions 11 are formed in a bag shape using a cloth different from the sheet a, and are arranged alternately in parallel along the width direction on the front and back surfaces of the sheet a, and correspond to the width and thickness of the soundproofing material b. It is sewn and attached to the front or back surface of the sheet a by the width thereof. Therefore, when the soundproofing material b is sealed in the storage section 11, the sheets a are alternately bent so that the end surfaces of the soundproofing materials 11 are close to each other and the soundproofing material 11 is arranged in a straight line,
A continuous soundproof wall surface is constructed, and one side end 12a of the folded portion 12 of the sheet a has a hinge function that allows it to be folded alternately.

In the above embodiment, in order to ensure the bending of the bending part 12, the attachment part of the sheet a located in the bending part 12 and the storage part 11 is brought into close contact with the adhesive 13. However, the present invention is not limited to this, and as shown in FIGS. 4 and 5, a reinforcing plate 14 may be applied to the corner portion of one side edge 12a having a hinge function of the bent portion 12, or to the corner portion and the back surface thereof. The reinforcing plate 14 may be fixed with screws 15 or bolts/nuts 16 to ensure the bending of the bent portion 12, but these are essential to the configuration of the present invention. It's not a requirement.
Further, the sheet a is not limited to being made of cloth, but may be made of resin.

Further, a locking tool 17 for locking an attached portion (not shown) is attached to one end of the sheet a in the folding direction, that is, the length direction.

Incidentally, if necessary, the locking members 17 may be attached to both ends of the sheet a in the folding direction. In this case, it is not only possible to fix the lower end when the soundproof wall A is hung and used, but also it is possible to use the soundproof wall A horizontally. Furthermore, by attaching the locking tool 17 to one end of the soundproof wall A in the width direction, it is also possible to use it like an accordion-type curtain.

Furthermore, on both sides of the sheet a in the width direction,
Overlapping portions 18 are formed that overlap with overlapping portions (not shown) formed on both sides of sheets constituting other adjacent soundproofing materials, and the overlapping portions 18 overlap with overlapping portions of other adjacent sheets. Resin fastener 1 that becomes a connector between sheets by locking each other
9 is installed. The connecting device is not limited to the resin fastener 19, and any method can be used as long as it can removably lock the overlapped portions of adjacent sheets, such as hooks and buttons. or,
One of the resin fasteners 19 may be provided at both ends of the sheet a in the width direction, and the overlapping portion of the other resin fastener 19 may be overlapped with this portion. In this case, the end faces of adjacent soundproofing materials are close to each other, and the soundproofing effect can be further enhanced.

In the above examples, the soundproofing material b was a known material made of styrofoam, glass wool, etc., which has a high soundproofing effect, and was cut into an appropriate size.

(Effects of the present invention) As described above, according to the present invention, bag-shaped storage sections for storing soundproofing material are arranged alternately on the front and back surfaces of the seat, and the storage sections are made of a material with high soundproofing effect. The formed soundproof material is enclosed to form a soundproof wall, and the soundproof wall is made foldable, so that it can be folded to make it compact during storage or transportation. Therefore, it can be easily stored, taken out, and transported.

Further, according to the present invention, it is only necessary to connect and disconnect the hook attached to one or both ends of the sheet to the attached part, and adjacent sheets can be connected and disconnected using a connector attached to the overlapping part of the sheets. Since it is arranged so that it can be installed and removed at the work site, it can be easily installed and removed.

Furthermore, according to the present invention, since the soundproofing material is wrapped in a sheet, the soundproofing material does not need to be as strong as conventional soundproofing walls.
This has the advantage of being lightweight and easy to carry.
