Description

  The present invention relates to a temporary enclosure temporarily installed around a construction site, and more particularly, to a green temporary enclosure capable of greening by planting a plant.

  As is well known, this type of temporary enclosure is temporarily installed around the construction site for the purpose of ensuring safety, preventing intrusion, blocking traffic, etc., and has constructed a single pipe as construction material vertically and horizontally. The most common type is a panel made of vertically oriented steel plates with a width of about 50 cm and a height of about 2 to 3 m on the outside of a simple frame. This kind of temporary fence greening has been widely used for the purpose of CSR activities.

  As an existing technique for greening the temporary enclosure, for example, a plant using a plant overgrowth unit as shown in Patent Document 1 or a sheet for holding a plant or soil as shown in Patent Document 2 is attached to the frame. A configuration is proposed.

JP 2003-174825 A JP 2004-141174 A

  However, all of those shown in Patent Document 1 and Patent Document 2 are costly to be temporarily installed, take time for installation and removal, and cannot always grow plants stably and reliably. Because there are many, it has not yet spread widely.

  In view of the above circumstances, an object of the present invention is to provide an effective and appropriate greening temporary enclosure that can be installed and removed very easily at a sufficiently low cost.

In the present invention, a large number of vertically long panels are arranged side by side on the front side of a cross member laid horizontally in three or more stages , and a greening unit having a size and shape that can be replaced with the panels is attached to the important points between the panels. By planting a plant in a greening unit, a temporary greening fence that is temporarily provided around the construction site, and the greening unit is filled with solidified soil in a bag formed of a sheet material. In addition, a plant can be planted in the solidified soil through a hole formed on the front side of the bag body, and the greening unit is mounted on the upper and lower parts of the bag body by the mounting tool. The greening unit is installed in multiple stages above and below the horizontal members that are horizontally mounted in three or more stages, and the lower mounting tool and the mounting tool of the greening unit installed in the upper stage. The position of the mounting tool in the upper part and the lower part of the greening unit in each stage is shifted laterally so that the position of the mounting tool in the upper part of the other greening unit installed in the lower stage does not overlap each other. To do.

  As a mounting tool for attaching the greening unit to the cross member, a belt-shaped hook-and-loop fastener (so-called magic fastener or magic tape (both are registered trademarks)) wound around the cross member can be suitably used.

Greening unit used in the present invention, it is preferable to form the water-retaining layer by sheet over preparative like or foundation-like water-retaining material in the surface layer of the upper or back side of the solidified soil.

  A pocket for planting a plant may be formed in the solidified soil, and an opening for exchanging the solidified soil may be provided at an essential part of the bag so as to be openable and closable.

  The material of the sheet material forming the bag body is arbitrary, but the sheet material on the back side is preferably a water-permeable material, and the sheet material on the front side is preferably formed of a flameproof material. It is also conceivable to reinforce these sheet materials with reinforcing materials such as wires and nets.

In the greening temporary enclosure of the present invention, a plurality of greening units may be installed in multiple stages so as to be vertically connected between normal panels, in which case the upper and lower mounting tools of the greening units in each stage do not interfere with each other. The position of the upper and lower mounting tools of each greening unit in the horizontal direction (so that the positions of the upper mounting tools of the upper greening unit and the upper mounting tools of the other greening units installed in the lower stage do not overlap) It is good to shift .

The green temporary enclosure of the present invention can be greened only by installing the greening unit in the form of replacing the normal panel at the main point of the normal temporary enclosure. It can be installed very easily on the material. Of course, when the temporary enclosure is dismantled, the greening unit can be easily removed, and the greening unit can be easily increased / decreased, changed in position, and replaced as necessary.
In addition, the greening unit in the present invention is basically a simple configuration in which a bag made of a sheet material is simply filled with solidified soil, and its shape and dimensions can be replaced with a normal steel plate panel. Thus, it is not large, and therefore it is lightweight, easy to handle, and can realize a sufficient cost reduction, and is optimal as a temporary installation on a construction site.
Furthermore, the greening unit according to the present invention can be provided even when the greening units having the same shape and dimension are installed in multiple stages so as to be connected vertically by shifting the positions of the upper and lower mounting tools of the greening unit in the horizontal direction. Therefore, a large number of greening units can be easily installed without gaps by repeating the same operation.

  In particular, if the mounting tool for attaching the greening unit to the cross member is a hook-and-loop fastener, the attaching / detaching operation to the cross member can be performed very easily, and the single pipe is concealed by the hook-and-loop fastener as the mounting tool. It is also possible to obtain a design-friendly appearance.

Also, if the surface layer of the upper or back side of the solidified soil previously formed water retention layer by sheet or base-like water-retaining material, is possible to spread the irrigation to the upper to the entire solidified soil through the water-retaining layer It can also prevent the solidified soil from drying.

By forming a pocket for planting a plant in the solidified soil, planting work of the plant there can be easily performed.
Further, by providing an opening for opening and closing the solidified soil at the important points of the greening unit, the solidified soil can be easily replaced or replenished as necessary.

If the sheet material on the back side of the greening unit is used as a water-permeable material, rainwater will naturally permeate into the solidified soil, and irrigation by sprinkling with a hose etc. from the back side of the greening unit (ie from the inside of the construction site) It becomes possible.
On the other hand, if the sheet material on the front side of the greening unit is used as a flameproof material, it is possible to ensure fireproof performance and fire spread prevention effect in case of emergency.
Furthermore, if these sheet materials are reinforced with reinforcing materials such as wires and nets, they will not be easily cut or torn, and sufficient strength and crime prevention performance required for temporary enclosures (prevention of intrusion) Function).

It is a schematic block diagram of the greening temporary enclosure which is embodiment of this invention. It is a schematic block diagram of a greening unit. It is a figure which shows the state which installed the greening unit in multiple stages so that it might be continued up and down. It is a figure which shows the structural example of the irrigation tube and water retention layer in a greening unit. It is a figure which shows the example at the time of providing the pocket for planting in the solidification culture soil similarly.

  Hereinafter, embodiments of the greening temporary enclosure of the present invention will be described with reference to FIGS. The greening temporary enclosure of this embodiment is a normal temporary enclosure by attaching the panel 2 made from a normal steel plate to the front side of the cross member 1 which consists of a single pipe horizontally mounted by four steps up and down, as shown in FIG. In the same way as above, it is temporarily installed around the construction site, but instead of the normal panel 2, a greening unit 3 is installed at a point between the panels 2, and plants 4 are planted there. By doing so, the panel 2 and the greening unit 3 as a whole can function as a normal temporary enclosure while realizing the greening of the temporary enclosure.

The greening unit 3 in the illustrated example has a width dimension equivalent to that of the panel 2 and a height dimension of 1/3 of the panel 2 (that is, a size obtained by dividing one panel 2 into three vertically), and a thickness of several centimeters (for example, 5 cm) As a substitute for one panel 2 with three greening units 3, the three greening units 3 are mounted between the horizontal members 1 in three stages so that they are vertically connected.
As shown in FIG. 2, each greening panel 3 is a bag body 5 formed of a sheet material filled with solidified soil 6, and has a hole 7 formed on the front side of the bag body 5. Through which the plant 4 can be planted with respect to the solidified soil 6.

The greening unit 3 is detachably attached to the cross member 1 by means of attachments 8 provided at the upper part and the lower part of the bag body 5, respectively. In the greening unit 3 of the present embodiment, the attachments are provided. 8, a belt-shaped hook-and-loop fastener wound around the cross member 1 (so-called magic fastener or magic tape (both are registered trademarks)) is employed.
In particular, in the present embodiment, the greening units 3 having the same shape and the same dimensions are installed in multiple stages as shown in the illustrated example, so that the upper and lower mounting tools 8 do not interfere with each other, that is, the upper greening unit. 3 so that the positions of the upper mounting tools 8 (8b) of the lower green 3 and the upper mounting tools 8 (8b) of the other greening units 3 installed in the lower stage thereof do not overlap. The positions 8a and 8b) are shifted laterally.
Specifically, as shown in FIG. 2, in the upper part of the greening unit 3, two mounting tools 8 b are provided at two intervals on both sides, but in the lower part of the greening unit 3, one mounting part is provided at the center. Tools 8b are provided, and the greening units 3 are mounted in multiple stages by alternately winding the mounting tools 8a and 8b around a common cross member 1 as shown in FIG. As a result, each greening unit 3 can be reliably and easily attached to the cross member 1, and the attachment members 8 are naturally concealed in the horizontal direction without gaps, and the cross member 1 is concealed. A favorable appearance can be obtained.

Various sheet materials can be used as the bag body 5 constituting the greening unit 3 as long as it can hold the solidified soil 6 and has a desired strength, but in particular the back side (inside the temporary enclosure) If the sheet material 9a is made of a water-permeable material, rainwater will naturally permeate the solidified soil 6, and irrigation by watering with a hose or the like from the back side of the greening unit 3 (that is, from the construction site) is possible. Become.
On the other hand, the sheet material 9b on the front side of the greening unit 3 is preferably made of a flameproof material, which can ensure fireproof performance and fire spread prevention effect in the event of an emergency.
Furthermore, if either or both of these sheet materials 9a, 9b are reinforced with a reinforcing material (not shown) such as a wire or a net, they can be prevented from being easily cut or torn, and a temporary enclosure. It is possible to ensure sufficient strength and crime prevention performance (intrusion prevention function) that are essential functions required for the system.

As the solidified soil 6 filled in the bag body 5, a spongy artificial soil excellent in water retention and drainage, particularly a seedling culture soil disclosed in, for example, JP-A-2002-058339 can be suitably used. According to this, it is possible to cultivate a variety of plants, but it is sufficiently lightweight but can hold a sufficient shape by itself, and collapses and sinks in the bag body 5 or a bag body caused by wind and rain. There is no fear of splashing or leakage.
As shown in FIG. 5, a pocket 10 is formed at the position of the hole 7 in the solidified soil 6 in the greening unit 3, and a root pot of the plant 4 grown in advance (the same soil as the solidified soil 6). May be arranged in the pocket 10 as it is, so that the planting operation can be performed more easily and the plant 4 can be easily replaced if necessary.
In any case, it is preferable to provide an opening (not shown) for exchanging the solidified soil 6 at an important point of the bag body 5 such as the upper part or the side part so that the solidified soil can be opened and closed. 6 can be easily replaced or replenished.

An irrigation tube 11 for supplying water to the solidified culture soil 6 is preferably incorporated in the upper part of the greening unit 3 as shown in FIG. Can be easily and reliably irrigated, and the plant 4 can be cultivated stably.
Further, instead of or in addition to providing the irrigation tube 11 on the solidified soil 6, as shown in FIG. 4C, the irrigation tube 11 made of, for example, a perforated tube is provided on the back side of the greening unit 3. It is also preferable to incorporate it along the vertical direction, whereby rapid irrigation is possible for the entire solidified soil 6.
These irrigation tubes 11 may be incorporated in all the greening units 3, but when the greening units 3 are installed in multiple stages as shown in the figure, it is assumed that water is supplied only to the uppermost greening unit 3. The greening unit 3 may be sequentially irrigated in a cascade manner. In that case, it is sufficient to install the irrigation tube 11 only in the uppermost greening unit 3.

Further, as shown in FIGS. 4 (a) and 4 (b), it is preferable to form a water retention layer 12 made of a water retention material such as a water retention resin on the upper surface layer portion of the solidified soil 6 so that water can be irrigated. Irrigation by the tube 11 can be distributed throughout the solidified culture soil 6 through the water retention layer 12, and drying of the solidified culture soil 6 can also be prevented.
Further, in addition to or instead of forming the water retaining layer 12 on the upper surface layer portion of the solidified soil 6, a similar water retaining layer 12 is greened as shown in FIGS. 2 (b) and 3 (b). It is also considered that the unit 3 is formed on the entire back surface side, whereby the solidified soil 6 can be irrigated more reliably and water retention can be further increased.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design modifications and applications are possible.
For example, the shape and size of the greening unit 3 may be set so as to be replaceable with a normal steel panel 2 for temporary enclosure, and as long as the height is half the panel 2, for example, one panel 2 in two stages It is also conceivable to replace the single greening unit 3 with a single panel 2 with a height equivalent to that of the panel 2 or with a height dimension equivalent to that of the panel 2. Of course, the position of the cross member 1 for mounting the greening unit 3 and the number of steps thereof may be set according to the height dimension and the number of steps of the greening unit 3 to be mounted.
Further, the width of the greening unit is not only the same as that of the panel 2 as in the above embodiment, but also the width of the panel 2 is an integer multiple of two panels or more. Replacement is possible.
However, if the greening unit 3 is made too large, the weight becomes excessive and inconvenient to handle, and considering the irrigation efficiency, one panel 2 is divided into two in the vertical direction as in the above embodiment. It is reasonable and practical to use a vertically long form as divided.

Further, as the mounting tool 8 for mounting the greening unit 3 to the cross member 1, the surface fastener as described above is optimal, but it is not limited to this, and it can be easily attached to and detached from the cross member 1. If necessary, appropriate metal fittings and clamps can be used.
The irrigation tube 11 and the water retentive layer 12 can be appropriately changed including omitting them, and may be optimally designed in consideration of the type of plant 4 to be planted and the growth environment.
The bag body 5 which is the main body of the greening unit 3 is also preferably made of a water-permeable material on the back side and a flameproof material on the front side as exemplified above. 4 as long as it has both the function that can grow 4 and the original function that is required as a temporary enclosure, as long as the sheet material as the material of the bag body 5 can be appropriately adopted, For example, a sheet material made of a fine mesh made of non-woven fabric or various materials can be adopted as well as a water-permeable material as a whole or a flameproof material as a whole. Of course, the bag body 5 may be arbitrarily colored or decorated.
As long as the solidified soil 6 can be stably maintained by itself so as not to collapse and sink in the bag body 5, it is optimal according to the plant 4 to be planted as long as it is. Use a solidified soil.
