Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a greened tree supporting structure, which is particularly suitable for greening a roof portion of a structure.

[0002]

2. Description of the Related Art Conventionally, in Japan, which has a shortage of land, it is a very serious social problem that there is little green space in the city center and its environment deteriorates year by year. Therefore, in order to eliminate the green space shortage in the city center, artificial ground is formed on the roof part of structures such as office buildings and factories with a relatively low utilization rate, and trees are planted on the artificial ground. Attention is being paid to attempts to alleviate the decrease in urban green spaces by greening even a little. When planting trees on such artificial ground, sufficient fall prevention measures must be taken to avoid the risk of the trees planted here falling due to wind, etc. The following measures are taken: forming the deepest possible ground and setting the roots of trees here, and attaching a support such as wood to the trunk of the tree.

[0003]

However, in order to form a deep artificial ground on such a structure, it is necessary to mount a large amount of soil on the structure, so that the structure itself is considerably damaged. It must be reinforced and modified to a structure that can withstand the loading of heavy objects, and its construction is extremely difficult. Especially when trying to plant a large tree on the roof of a high-rise building, it takes a long construction period and construction cost because it requires a deeper artificial ground to support the large wind load on the tree. It is difficult to replant here unless the entire structure is significantly strengthened and modified. Of course, if you attach a solid support for fall prevention to the trunk of the tree and fix it on the roof, you will not fall even if the amount of soil is small, but in this case, the aesthetic appearance is remarkable. In addition to the damage, it becomes difficult to supply water and nutrients necessary for the growth of trees, that is, maintenance becomes complicated accordingly. Therefore, in view of the above circumstances, the present invention can prevent the trees from tipping over even with a small amount of soil, can be easily installed without requiring significant strengthening and modification of the structure, and is easy to maintain. , To provide a greening tree support structure.

However, as shown in FIG. 1 or FIG. 2, several PC boxes 3a each have roots 7a of the PC box 3a extended and expanded in the artificial soil 6 to be planted.

On the upper part of the soil support frame 3, a wire 10 formed in a fiber bundle shape is used to remove a tree 7 from its root 7a and trunk 7.
A plurality of wires 10 are stretched so as to be tightly bound and supported in the vicinity of b, and each of the wires 10 extends in the vertical direction of FIG. 2 or the horizontal direction of FIG. 2 as shown in FIG. Are arranged in a grid pattern. Each wire 10 can be tensioned via a wedge-type fixing jig 12 attached to the end portions 10a, 10a shown on the left or right of FIG.
The end portions 10a, 10a are connected and supported by the PC boxes 10a, 10a corresponding to the outer peripheral portions of the soil support frame 3 on which they are arranged. The wire 10 is, as shown in the left part of FIG.
As shown in the right part of FIG. 3, a plurality of types of resin wire elements 11 each having different properties are formed in a bundle shape so as to be braided into a braid, and each wire element 11 is In the form in which the fibers constituting the wire element 11 have their orientation directions substantially aligned with each other, each of the wire elements 11 retains and maintains different properties. That is, some of the plurality of types of wire elements 11 are wires 10.
Is composed of high-strength fiber for maintaining strength in a shape corresponding to the tension force introduced into, and some are composed of high-permeability coefficient holding fiber for supplying water to the tree 7, , Some are made of conductive fibers for electric heat supply and temperature control, and some are made of water-holding fibers for supplying and holding the nutrients necessary for the tree 7, and further Are made of optical glass fibers for lighting the green structure 2. The wire 10 is formed by braiding a plurality of these wire elements 11 in a braided shape, then impregnating the fastening resin, and hardening the fastening resin to integrally bond them. It possesses multiple properties.

Since the greening structure 2 has the above-mentioned structure, in order to construct the greening structure 2, first, the PC box 3a, which is molded in a predetermined shape in advance by factory processing or the like, is greened. It is conveyed to the roof 1a of the building 1 which is the construction site to be constructed, and is arranged at a predetermined position on the roof 1a so as to be lined up without a gap as shown in FIG. Then, the respective PC boxes 3a are appropriately attached to the rooftop 1a via anchor bolts or the like.
The soil support frame 3 is supported by the structure 1 in a form in which a plurality of PC boxes 3a are closely integrated with each other by fixedly arranging the parts on the part. In addition, a plurality of wires 10 are attached to the soil support frame 3,
As shown in FIG. 2, the both ends 10a and 10a of the soil support frame 3 are temporarily fixed to and supported by the PC box 3a located here, in a state where tension is not yet introduced through the fixing jig 12. Keep it.

Then, several trees 7 are provided in each PC box 3a.
Is introduced into the wire 10 through the fixing jig 12 in the order described above, whereby the roots 7 of each tree 7 are
A predetermined number of plants are planted in such a manner that the vicinity between a and the trunk 7b is properly bound and supported. Along with this, the artificial soil 6 with an appropriate composition of a shape suitable for the tree 7 is provided in each PC box 3a.
The root 7a of the tree 7 is properly arranged and accommodated. In this way, all the trees 7 that are set to be planted in the greening structure 2,
When a predetermined number of the roots 7a are stretched in the artificial soil 6 in each PC box 3a so as to be tightly supported by some wires 10 corresponding to the trees 7, the artificial soil 6
The upper surface 6a of the fixing member 12 is appropriately evenly laid and slightly rolled, and at the same time, each wire 10 is fixedly supported by both ends 10a and 10a shown in the left and right sides or the upper and lower sides of FIG.
A predetermined tension is introduced via 12.

Then, among the wire elements 11 constituting the wire 10, some of the wire elements 11 are made of high-strength fiber for maintaining strength in a shape corresponding to the tension force introduced into the wire 10. From a certain point, each wire 10 can give sufficient prestress to the soil support frame 3,
As shown in FIG. 2, a plurality of wires 10 are stretched on the PC box 3a corresponding to the outer peripheral portion of the soil support frame 3 in a lattice shape along the plane direction of the soil support frame 3. As a result, the structure 1 has a plurality of trees 7 suitable for the landscape of the structure 1.
However, a predetermined tension force is introduced so that the tree 7 is tightly supported by some wires 10 stretched between the PC boxes 3a, 3a, and thus the tree 7 is given sufficient tension force. As shown in FIG. 1, even if the minimum amount of soil required for the growth of the tree 7 is kept in a form in which it is prevented from falling over by the several wires 10 provided, as shown in FIG. Stablely planted in a stretched form.

In this way, the construction of the greening structure 2 is completed, but the soil support frame 3 used for the greening structure 2 is formed by simply arranging the PC boxes 3a made of precast on the rooftop 1a. Therefore, it is easy to handle and is installed with a very simple construction procedure. Since each PC box 3a is made of precast, the PC box 3a is configured in addition to the fact that it is possible to preset the desired shapes and properties required for it. By disposing the reinforcing bar 5 made of resin fibers bundled in a braid shape in the structural material, it is possible to reduce the weight and maintain sufficient strength. Further, by using such a material that does not rust (excellent in durability) as the reinforcing bar 5, it is possible to use a porous concrete material for the PC box 3a, thereby obtaining high water permeability, and thus artificial soil. 6 can always be kept in good condition. And artificial soil 6
Also, as is known, it is possible to reduce the weight of the tree 7 in a form that is sufficiently suitable for growing and maintaining the tree 7. Therefore, the greening structure 2 applies only a minimal weight load to the structure 1 while maintaining its structural stability such as preventing the trees 7 from falling and the soil support frame 3 having sufficient strength. Therefore, there is no need to strengthen or modify the entire structure of the structure 1 in order to green the rooftop 1a.

By the way, each tree 7 of the greening structure 2 is in the form of being tightly bound and supported by the wire 10 between the root 7a and the trunk 7b of the tree 7, and the wire 10 is
By adjusting the volume of the artificial soil 6, the soil 6 can be buried in the soil 6, as shown in FIG. 1. Therefore, a plurality of trees 7 are like natural trees that stand on the rooftop 1a. With it, it is possible to present an extremely excellent landscape. And
The wire 10 is composed of wire elements 11 having different properties, such as high permeability coefficient holding fiber, conductive fiber, water retaining fiber, and optical glass fiber, and possesses a plurality of properties corresponding to these respective fibers. Therefore, among the wires 10, an appropriate wire element 1 corresponding to each purpose is provided.
1 can be used through the artificial soil 6 to supply water and nutrients to the tree 7 or to supply electric heat to manage the temperature suitable for the maintenance and growth of the tree 7.
However, it is possible to maintain a good growth state while maintaining it very easily. Furthermore, it is possible to light up the entire greening structure 2 to improve the scenery at night, and finish the greening structure 2 as the most suitable for improving the scenery in the city and maintain it. Can be done easily.

[0014]

As described above, according to the present invention,
It has a frame such as a PC box 3a which is formed in an open shape so as to accommodate a tree cultivation board material such as artificial soil 6 inside, and the frame is fixedly arranged on a construction site such as a rooftop 1a to be greened. And the wire 10 formed in the frame into a fiber bundle shape.
A plurality of tree supporting means such as a tree are stretched in a tensionable manner, and trees such as trees 7 for greening are planted in the frame so that the tree supporting means binds and supports them. , Can be placed on the construction site in a form that is tightly supported by the tree supporting means. Therefore, if the tree is firmly bound and supported by tensioning the tree supporting means, the root of the tree such as the root 7a is stretched in the deep soil, or the trunk of the trunk such as the trunk 7b is firmly supported. Even if it is not installed, the risk of the tree falling is sufficiently avoided even when the amount of soil is small. That is, since it is not necessary to mount a large amount of soil on the construction site, there is no need to reinforce the entire construction site to a structure that supports the large volume of soil. In addition, since the frame does not need to contain a large amount of soil, it can be factory-processed with a lightweight material. Therefore, installing a greening structure such as the greening structure 2 at the construction site is the minimum. Can be easily done with the work of. Furthermore, since the tree support means is tensionable, the tree does not need to have its trunk portion supported by the tree support means, and therefore the tree support can be removed from the construction site, which results in greening. The structure has an excellent appearance. Further, since the tree supporting means is formed in a fiber bundle shape, by selectively using the fibers constituting the tree supporting means, it is possible to sufficiently replenish the water and nutrients necessary for the growth of the tree. The maintenance can be facilitated, and the trees can be maintained in a good growth state, which can greatly contribute to the remedy of insufficient greening in the city. In addition, when the tree support means is formed by forming a plurality of types of fiber element aggregates such as resin wire elements 11 made of resin having different properties into a bundle shape by braiding in a braided shape, there are a plurality of tree support means. Can possess different properties of. Then, the tree supporting means can supply water, nutrients, electric heat, etc. by utilizing each property of the fiber element assembly material, instead of merely supporting the tree in a form to prevent it from falling. Therefore, it is easier to maintain the tree so that it exhibits the best growing condition. Furthermore, by lighting the tree, the aesthetics of the tree can be further improved, so that a design-added value is generated at the construction site to which the greening structure is applied. Therefore, it is possible to easily and beautifully green the rooftops of structures in areas where there is little green space, to maintain this without effort, to make the scenery around it comfortable, and to significantly improve the environment in that area.
