DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for making a self-supporting wall such as a fence or a roof of a private house or a shield wall of a mechanical facility a more effective soundproof structure and, at the same time, greening the entire wall surface. is there.

[0002]

2. Description of the Related Art Sound insulation walls of roads and fences of private houses are intended to be blindfolded and soundproof. However, most of the sound insulation walls have recently been made of metal panels, and the sound is generally transmitted to the wall surface and leaked to the outside, or the sound is reflected on the wall surface and the inside is generally noisier. Concrete structures not only impair the landscape, but also reflect the sun's rays and cause environmental degradation. On the other hand, concrete blocks, which are often used for private house fences, have a low soundproofing effect because the surface reflects sound, and the surrounding scenery is also poor.

[0003] In recent years, attention has been paid to techniques for greening these concrete structures and walls. By the way, the method of greening the walls of self-supporting walls with climbing plants has been known for a long time.However, in many cities, there is often no soil base for planting plants. In most cases, it is in a bad place or the soil is poor. Therefore, there is a problem that it is necessary to improve the soil and replace the soil, which takes time and costs. In addition, there is a problem that it takes too long for plants to grow sufficiently and green the entire wall, which cannot be fundamentally solved.

Therefore, as a structure for planting directly on the wall,
JP-A-63-75142 discloses a plant cultivable panel. In the configuration of this conventional example, a soil material for plant cultivation is interposed between a pair of panel materials, and can be adopted as a wall of a self-standing wall.

[0005]

However, in the conventional example, soil is adopted for plant vegetation, and the panel becomes heavy as a whole, so it is difficult to handle the panel at the time of construction, and the inside is filled with soil having a large specific gravity. Therefore, the strength of the structure as a panel must be increased. Furthermore, there is a problem that the lower part of the soil is compacted by its own weight due to external vibration after installation. In order to solve this problem, a partition is formed by a horizontal piece in the conventional example. However, there is still a problem that the compaction caused by vibration cannot be fundamentally eliminated in each section. Further, in the above conventional example, no configuration for soundproofing is considered at all.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems. A self-standing wall is formed by a simple and lightweight structure, and both sides of the wall are surely greened and the wall functions as a soundproof wall. It is an object of the present invention to provide a wall structure that can be used. Applicable places include fences in houses, noise barriers on expressways, and walls for blindfolding machines.

[0007]

In order to achieve the above object, the wall structure of the present invention has an opening at the upper surface, a plurality of through holes on each of the four peripheral walls, and a drain port below the both side surfaces. Box, a plurality of water absorbers laminated inside the box, and a drain formed in the lowermost layer of the box facing the drain port.
A water tank and an upper surface of the drainage tank support the water absorber.
Along with stacking a plurality of box-shaped walls consisting of a net-like body that can be drained together, and supporting and fixing both ends of these stacked box-shaped walls with support columns, respectively, provided on the front and back of the box-shaped wall A means of planting through the plurality of through holes provided above was used.

According to a second aspect of the present invention, instead of the means for laminating a plurality of moisture absorbers inside the box according to the first aspect, a frame having an open front and back is divided into a plurality of planting spaces by a lattice frame. In each of the plurality of planting spaces, a unit shelf filled with artificial planting base material was used.

Further, a means for selectively forming a drainage tank facing the drainage port on the lowermost layer of the box and supporting the upper surface of the drainage tank with a net capable of draining and supporting the water absorber is selectively used. I decided that.

Further, the frame body having the open front and back surfaces is divided into a plurality of planting spaces by a lattice frame, and a plurality of through holes are formed in the frame body and the lattice frame. Both ends of the unit shelf filled with the artificial planting base material are fixedly supported by support columns, and a means for planting in the planting space from at least one of the front and the back is selectively used.

[0011]

[Function] The box-shaped wall functions not only as an original wall but also as soil for planting plants. In particular, in claim 1, the plurality of moisture absorbers, and in claim 2, the artificial planting base material acts as a substitute soil, and has functions of water retention and ventilation. Of the through-holes provided on the wall around the four sides of the box, the through-holes provided on the front and back sides allow plants to absorb moisture from outside,
Alternatively, it has a function for planting the artificial planting base material, and the through-holes provided on both side surfaces function as vents to the inside of the box-shaped wall. Further, the drainage port performs a drainage action of surplus water that cannot be retained by the water absorber, and drains surplus water accumulated in the drainage tank. Drainage tank
The mesh on the top drains excess water and absorbs moisture.
It has the function of preventing collapse of the body .

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view showing a first embodiment of a self-standing wall according to the present invention, wherein 1... 1 are a plurality of box-shaped walls, and in this embodiment, three are stacked. However, the number to be stacked need not be limited to this embodiment. 2 is these box-shaped walls 1
.. Are support columns for supporting 1 so as not to collapse. In the embodiment, H steel is used. The details of the box-shaped wall are such that a large number of through-holes 4... 4 are formed on the four surface surfaces of a horizontally long box 3 whose upper part is open as shown in FIGS. 2 and 3. Of the through holes 4, the through holes 4a provided on the front and back sides are used for planting, and the through holes 4b provided on both side surfaces are used as vent holes. Reference numeral 5 denotes a drain port provided below the short side wall surface on both sides, and has a structure for draining surplus water accumulated at the bottom of the box 3 to the outside. The box 3 is preferably lightweight, and is formed by compression molding of urethane foam, but the material is not limited to these. However, when the foamed material is used, the heat insulating property is good, the freezing inside can be suppressed even in winter, and the soundproofing and the sound insulating effect are further enhanced by the intervening air layer.

FIG. 4 shows a state in which the box-shaped wall body 1 is assembled on the support column 2.
Is matched with the outer thickness b of the box-shaped wall 1, and the box-shaped wall 1 is sequentially stacked on this portion. In this way, the box-shaped wall 1
Are held by the interval a of the web W, it is possible to reliably prevent slippage and collapse. In addition, the space formed by the web W and the side surface of the box-shaped wall 1 functions as a ventilation part and a drainage part.

FIG. 5 is a vertical sectional view showing the box-shaped wall 1 filled with a material functioning as an alternative soil for planting plants. As a moisture absorber that substitutes for soil, mats 6... These mats 6... 6 serve as a root growth base when the plant is propagated, and form a water retention layer and an air layer. The mats 6 are stacked horizontally. In this way, the water can be held appropriately below each mat, so that the water holding amount is uniformly dispersed as a whole. Therefore, it is possible to avoid the disadvantage that the lower layer exceeds the water holding capacity while the upper layer alone is too dry. However, in order to more uniformly retain water in the upper layer and the lower layer, a nonwoven fabric having higher water retention performance than the lower layer can be freely used for the upper layer. Reference numeral 7 denotes a drainage tank housed in the lowermost layer and having a U-shaped cross section, and communicates with the drainage port 5. The reason why the drainage tank 7 is provided is to prevent the lower layer mat 6 from always having excessive water retention, and furthermore, the drainage cycle of the water being maintained by making the box-shaped wall 1 a unit of a constant height. This is for improving clean water and supplying clean water. The upper surface of the drainage tank 7 is covered with a mesh line 8 which is a net-like body in order to prevent the mat 6 from dropping and to drain excess water. It should be noted that the mesh streaks 8 can be replaced with a grid in the form of stripes or diamonds, or the shape can be changed as appropriate. Here, the condition required for the mesh body is that the mat 6 has sufficient strength to prevent the mat 6 from dropping, and that excess water is drained. Further, as shown in FIG. 6, instead of means for assembling the drainage tank 7 separately from the box 3 as in this embodiment, the inner wall of the part functioning as the drainage tank 7 is made thicker. A step 9 may be formed, and the mesh streaks 8 may be integrally formed in the vicinity of the step 9 by insert molding.

Reference numeral 10 denotes a water supply pipe provided on the uppermost layer of the mat 6 accommodated in each box-shaped wall body 1 for preventing the mat 6 from drying and dying the plants. is there. In the present embodiment, the boxes 3 are stacked closely in the up-down direction, and the only contact with the outside is through hole 4.
It is difficult to expect natural water supply by rainwater.
Therefore, a configuration in which water is forcibly supplied by the water supply pipe 10 is employed. The water supply pipe 10 has a number of water supply holes formed around it. As a water supply structure, water supply conditions and the like can be properly controlled by forming a plurality of orifices on the surface of a water supply pipe and using a drip tube in which water is dripped evenly from each orifice. However, instead of this, it is also possible to use a porous water supply pipe in which fine holes are formed, and to uniformly leaching water from the entire surface of the water supply pipe with water pressure.

As another embodiment for forcibly supplying water, a rainwater trap 11 may be provided as shown in FIG. The rainwater trap 11 captures rainwater flowing down the wall of the box-shaped wall 1 and supplies water to the mat 6 filled in each box 3. The rainwater collected by the rainwater trap 11 contains dust adhered to plants and walls above it in a state of being washed away, so that if the water is supplied as it is, the mat 6 is undesirably polluted. Therefore,
On the water supply side of the rainwater trap 11, for example, a filter 11a
In some cases, dust is removed by providing a device.

With respect to the wall constructed as described above, if a suitable plant is planted on the mat 6 through the through-holes 4a provided on the front and back of the box 3, the plant can be removed from each through-hole 4a. And the greening wall is completed early. Further, since an air layer composed of the mat 6 is formed between the front and back surfaces of the box 3, sound is well blocked, and it is also effective as a soundproof or sound insulating wall. In the present invention, instead of the mat 6 shown in the embodiment, for example, a large number of water-absorbing bodies made of cotton, for example, may be laminated as a water-absorbing body.

FIG. 8 is a plan view showing another embodiment of the box-shaped wall, and a longitudinal section may be formed in a vertical direction by a pair of partitions 12a and 12b. And partition 12
When a plurality of through holes are provided in a.12b and the gap is made a space, the air permeability to the moisture absorber is further improved, and the planting conditions are further improved.

Next, a second embodiment of the self-standing wall of the present invention will be described. In this embodiment, a self-standing wall is constructed by loading a unit shelf 20 for planting in the box-shaped wall body 1 instead of the means for filling the nonwoven fabric mats 6... 6 adopted in the first embodiment. As shown in FIG. 9, the details of the unit shelf 20 are such that a plurality of planting spaces 23 are formed by dividing a frame body 21 having an open front and a back with a lattice frame 22. Frame 2
A plurality of through-holes 24 are formed in the four peripheral plates 21a and the vertical and horizontal plates 22a of the lattice frame 22 to communicate with the through-holes 4 of the box-shaped wall body 1 to provide air permeability and water permeability, and to provide the roots of the plant. Freedom for growth. In the planting space 23, granular cotton,
An artificial planting base material 25 containing a mixture of wood fiber, non-woven fabric and the like is filled. Reference numeral 26 denotes a water supply pipe disposed above the unit shelf 20 and has the same function as the water supply pipe 10 of the first embodiment. The mixing ratio of the artificial planting base material 25 is appropriately changed according to the plant to be planted, the environment of the construction site, and the like, and the water retention and air permeability in the planting space 23 are adjusted.
Further, artificial planting base materials 25 having different mixing ratios may be filled for each planting space 23. Furthermore, by molding the unit shelf 20 with a foamed resin material, the weight can be reduced, and an excessive load is not applied to the box-shaped wall 1.

FIG. 10 shows the vertical sectional structure of the wall of the second embodiment. When the stacking of the box-shaped wall body 1 in which the unit shelves 20 are previously loaded is completed, the plant P can be planted in the planting space 23 through the through-holes 4 of the box body 3 to construct a greening wall body. . Therefore, according to this embodiment, preparation for planting, that is, filling of the box-shaped wall body 1 with the moisture absorber having a soil function does not take much time, and the workability at the site can be improved. Was.

In the second embodiment, the unit shelf 20 was loaded into the box 3 to construct a self-supporting wall, and the greening wall could be provided with structural strength. The unit shelves 20 may be directly fixed by support columns to form a self-standing wall. In this case, a greening wall can be provided with better workability.

[0022]

According to the present invention, a plurality of box-shaped walls are stacked and supported on a support column. These box-shaped walls are formed by laminating a water absorber inside and planting them through through holes. Therefore, plants could be planted on any part of the wall, and greening of the entire wall could be easily achieved. Also, as another means, a unit shelf having a planting space is loaded inside the box-shaped wall, so that the same effect as when the above-described moisture absorber is laminated can be obtained with respect to the wall greening, and the planting is performed. It was only necessary to load the unit shelves into the box as preparation before planting, and the workability at the site could be further improved. When the unit shelves are directly fixed by the support columns, the structure of the greening wall can be simplified, and the cost can be reduced. Furthermore, since the unit shelf is partitioned into a plurality of planting spaces, various planting environments can be constructed by using each planting space as an independent planting compartment.
Also, since the number and diameter of through-holes in the box can be varied depending on the plant to be planted, the greening density can be predicted in advance, and it is very effective if adopted for planned regional greening. Configuration.

Further, since the box is hollow and a moisture absorber is stacked inside or a unit shelf having a planting space filled with an artificial planting base material is loaded, a water absorbing member containing a large amount of air is absorbed. Because it is a structure that blocks the body or artificial planting base material with two wall surfaces, the soundproofing or soundproofing effect is large, and it can be used for noise countermeasures along with the improvement of the landscape, and the effect is enormous. .
