Description

Description: TECHNICAL FIELD The present invention relates to a method and an apparatus for fixing a planting base used for planting trees on a roof of a building or a concrete floor of an underground structure.

[Conventional technology]

Recently, it has been practiced to form topsoil on the rooftop or on the concrete surface of an underground structure, and to plant trees on it.

In such a planting method, a root pot is inserted into a root hole excavated in the surface soil on the concrete floor surface of the structure, and then the soil is buried in the void of the root hole to make the tree self-supporting.

[Problems to be Solved by the Invention] However, when the tree to be planted becomes large, a means for preventing tilting against wind pressure etc. is required, but unlike the case of general soil, the topsoil is thin, so a pillar or It is not preferable because the anchor burial depth cannot be secured sufficiently, and the pillars or branch lines are exposed on the topsoil, which may damage the landscape and further damage the concrete floor by the anchors.

The present invention has been made in view of such circumstances, particularly when planting trees on the topsoil of the roof of a building or on the concrete floor of the underground structure, reliably support the root pot in the soil, It is an object of the present invention to provide a method and an apparatus that can favorably stand on a concrete floor without damaging a concrete floor and without tilting even when a tree is hit by a strong wind.

[Means for Solving the Problems]

In order to solve the above problems, the present invention, in fastening a root pot of a tree to be planted to a planting base placed on a concrete floor, a stripping agent at a required location of the concrete floor along the planting base. After the applied release plate is adhered and the release agent is cured, the surface layer portion of the concrete floor is released together with the release plate, and then the anchor is fixed to the release portion of the concrete floor surface layer portion with an adhesive. ,
Next, a method of fixing the planting base is characterized in that the planting base is fixed on the concrete floor via the anchor.

In addition, a grid-shaped planting base is formed by fixing hooks to required places on the upper surface of the periphery, and a screw rod is protruded to an angle-shaped outer surface that sandwiches the peripheral members of the planting base from required sides. It has anchors that are fixed, and an adhesive is attached to the bottom surface of these anchors to fix them on the concrete floor, and connect the connecting plates to both screw bars of the anchors that project above the planting base and fasten them. This is a planting base fixing device characterized by the above.

[Action]

According to the method for fixing the planting base of the present invention, the fragile surface layer portion of the concrete floor is peeled off by the peeling plate, the solid concrete floor surface of the lower layer is exposed, and the anchor is bonded to the exposed surface with an adhesive. Therefore, the anchor can be firmly joined to the concrete floor.

Then, since the planting base is fixed to this anchor, the planting base is joined very firmly to the concrete floor.

In addition, since the anchor is joined to the concrete floor by sandwiching the required parts of the peripheral members of the planting base from both sides, it is possible to take a wide joint surface with the concrete floor and to handle a large lateral load. The planting base does not easily come off the concrete floor.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The present invention will be described with reference to the drawings. FIG. 1 (a) is a perspective view of a planting base 1 according to the present invention. The hook 2 is fixed to the.

FIG. 1 (b) is an exploded perspective view of a device for fixing the anchor 3 of the planting base 1. The anchor 3 is formed by fixing the screw rod 5 on the outer surface of the angle shape in a protruding state.
A connecting plate 4 formed with two perforations 4a and 4a with a space slightly wider than the width of the peripheral member 1a of the planting base 1 is inserted and attached to the planting base 1, and is fastened with a nut 6 via a washer 7.

FIG. 2 (a) is a cross-sectional view showing a state in which the peeling plate 10 for peeling off the surface layer portion 13a of the concrete floor 13 is fixed to the concrete floor 13, and the bottom surface of the peeling plate 10 has a peeling agent 12
Is applied and the second along the peripheral member 1a of the planting base 1
As shown in FIG. 2 (b), the concrete floor 13 is bonded to the required places.

FIG. 3 (a) is a cross-sectional view showing a state in which the surface layer portion 13a of the concrete floor 13 is peeled off. After the peeling agent 12 is hardened, a hammer or the like is laterally attached to the handle 11 attached to the peeling plate 10. When the impact is applied with, the fragile surface layer portion 13a of the concrete floor 13 is easily peeled off while being attached to the peeling plate 10, and the concrete floor 13 is exposed with a solid exposed surface 14 shown by diagonal lines in FIG. 3 (b). .

FIG. 4 (a) is a cross-sectional view showing a situation in which the anchor 3 is fixed to the exposed surface 14 of the concrete floor 13, and the adhesive 8 is applied to the bottom surface of the anchor 3, and the adhesive surface is planted. Each exposed surface 1 while sandwiching both sides of the peripheral member 1a of the plant base 1
4 and is adhered to a required portion of the peripheral member 1a of the planting base 1 as shown in FIG. 4 (b).

FIG. 5 (a) is a cross-sectional view showing a state where the connecting plate 4 is fixed to the anchor 3, and after the adhesive 8 of the anchor 3 is cured,
The holes 4a, 4a of the connecting plate 4 are inserted into the screw rods 5 exposed from the anchor 3, and the nut 6 is inserted through the washer 7.
And fasten the anchor 3 as shown in Fig. 5 (b).
The planting base 1 is fixed on the concrete floor 13 surface.

After fixing the planting base 1 to the concrete floor 13 in this way, as shown in FIG. 6, the root pot 15 of the tree 18 is placed on the planting base 1, and the wire 16 is hung on the hook 2 to attach the root pot 15 to the plant base 15. 18 trees on the planting base 1 by concluding
In this way, the top soil 17 covering the root pot 15 is buried on the concrete floor 13 and the planting of the trees 18 is completed.

〔The invention's effect〕

According to the present invention described above, since the anchor is fixed to the solid exposed surface from which the fragile surface layer portion of the concrete floor is peeled off, the anchor can be firmly joined to the concrete floor. Also, since this anchor is joined to the concrete floor by sandwiching the required parts of the peripheral members of the planting base from both sides, it is possible to take a wide joint surface with respect to the concrete floor. The planting base will not be easily peeled off from the concrete floor under a large load.

Therefore, in the present invention, since anchors or stanchions are not required to self-support the tree, the concrete floor surface is not unnecessarily damaged, and the tree self-sustains strongly even if the surface soil of the concrete floor surface is thin. This is something that can be done, and since it does not require props or branch lines, it does not spoil the landscape.
It is optimal for planting trees on the roof of a building or on the concrete floor of an underground structure.
