Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a planting stabilization device used to stably hold a tree during planting, and in particular, a coupling device that mutually connects a plurality of planting stabilization devices arranged in the vicinity on a substantially horizontal plane in order to meet the demand for rooftop greening. Planting stabilizer with About.
[0002]
[Prior art]
Conventionally, when planting trees on the ground surface, in order to be able to withstand strong winds, etc., a planting stabilization device has been installed at the bottom of the excavated planting hole, and a root pot of the tree has been placed on top of it. The pot is tied to a planting stabilizer and then the planting hole is backfilled. A variety of such planting stabilization devices are known, and usually a belt is connected to a locking ring locked to an arm in a state where a root pot is placed on a metal arm formed with a frame. At the same time, it is passed over the shoulder of the root pot, and the root pot is tied to the arm via the winch.
[0003]
By the way, in recent years, greening on the roof of buildings has been desired from the countermeasures against the heat island phenomenon and the like, and it is gradually spreading. In such scenes, the role of tree planting stabilizers has attracted attention.
[0004]
In this regard, the conventional tree-planting method for greening the roof is arranged on the roof with a rectangular mesh member in which wires are arranged vertically and horizontally, and after fastening the mesh member and the root pot placed thereon with a belt, There is a method to cover the soil.
[0005]
[Problems to be solved by the invention]
However, in the case of the conventional method using a mesh member made of a wire rod, it is necessary to fill the mesh space formed below the root pot so that the earth (artificial soil) can reach, and the filling is insufficient. There is a problem that it will fade after a lapse of time. In addition, when the belt spanned over the root pot is tightened strongly, the wire is curved and it is easy to generate such an unfavorable space. In addition, the mesh member is formed in a rectangular shape corresponding to each individual root pot to be planted, and because there is a limit on the width dimension, there is also a limit in the tension force against the moment in the direction in which the tree falls, and the retention of the tree There is also a problem in terms of power.
[0006]
Therefore, for rooftop greening, it is desirable to provide a device similar to the planting stabilization device used for tree planting on the ground surface. Therefore, sufficient consideration should be given to this point for the planting stabilizer.
[0007]
(1) As shown by the arrows in FIG. 1, the wind speed and the wind pressure with the distance from the ground surface are relatively small near the ground surface due to the influence of buildings and trees, etc. Gradually grows. Such a phenomenon becomes more prominent as the building becomes taller. In the case of the rooftop of a general building such as a 10-story building, the wind speed and pressure are said to be 1.5 times or more of the ground surface. Therefore, when the weather is bad, such as a typhoon, a tree planted as a rooftop greenery has an unimaginable wind speed and pressure, and the risk of falling trees is extremely high. In the unlikely event that a fallen tree falls from the roof to the ground, there is a danger of causing a serious accident. For this reason, the holding power of tree planting by the tree planting stabilization device and the strength required for the device itself must be studied very strictly.
[0008]
(2) In this regard, when planting on the ground surface (local board), it is possible to firmly fix the planting stabilizer by driving the anchor into the local board inside the planting hole. However, in the case of rooftop greening, such an anchor cannot be used in order to prevent the risk of damage to the building frame and to ensure waterproofness.
[0009]
(3) In the case of tree planting on the ground surface, the ground can be solidified by refilling the planting hole with the same type of earth and sand as the local board, and the planting stabilizer can be fixed by its own weight and the weight of the earth and sand. On top and on the roof, the weight is limited, and it is necessary to reduce the weight of the device freely. Of course, lightweight artificial soil is also used for embedding root pots, so it is fixed by weight as on the ground surface. Is difficult.
[0010]
(4) In addition, when planting trees on the ground surface, it is possible to excavate deeply into the planting hole, but it is not possible to excavate the hole on the roof, and it is filled due to the above-mentioned weight restrictions. The layer thickness of the soil is limited, and usually the height of the planting hole is as shallow as 30 to 40 cm, so that it is not possible to fix firmly from this point.
[0011]
(5) Furthermore, in rooftop greening, it is necessary to have a long plant life for the planting stabilizer, because it takes a long time for the roots to settle and become independent as a result of selecting slow-growing tree species, shrubs or medium trees. Don't be.
[0012]
By the way, in order to provide a planting stabilizer that satisfies the high holding power and longevity of trees under various constraints and conditions on the rooftop, a plurality of planting stabilizers arranged in the vicinity are mutually connected. It is desirable to secure the holding power of the tree and the strength of the device as a whole.
[0013]
In this regard, the present inventor has previously proposed a tree planting stabilization device according to Japanese Patent Application No. 9-103876 (Japanese Patent Laid-open No. 10-276594). By connecting an additional beam unit in a direction parallel to the arm to the beam unit, the tree planting stabilizer can be deployed while being spread on a horizontal plane.
[0014]
However, as a result of further research, the present inventor has found that in the case of rooftop greening, tree planting is generally performed in a desired arrangement form and arrangement direction within a limited small area. It has been found that a configuration in which the arm can be expanded only in a predetermined direction as in the technique proposed in (1) is insufficient.
[0015]
Therefore, the present invention is a tree planting stabilization device that overcomes the various restrictions and conditions in rooftop greening as described above, and is capable of arbitrarily connecting a plurality of tree planting stabilization devices, and also supports each tree supporting each tree. An object of the present invention is to provide a coupling device in a tree planting stabilizer that realizes the freedom regarding the installation position of the tree planting stabilizer.
[0016]

Connecting device for detachably connecting adjacent tree stabilizers in the state of being close to each other Have The connecting device is provided with connecting angle adjusting means for making adjacent tree planting stabilizers mutually rotatable on a substantially horizontal plane.
[0017]
At this time, the tree planting stabilization apparatus includes a resistance plate device that is detachable in the vicinity of the tip of the arm, and is configured to include a deposition member on the resistance plate device. A bracket member that is detachably attached to the arm and extends in the direction in which the arm extends, and an insertion sleeve provided in the vicinity of the tip of the bracket member, and is positioned between the attachment member and the insertion sleeve to adjust the coupling angle. In a state where a plurality of planting stabilizers each having a resistance plate device and a coupling device attached to each other, one end portion is inserted into an insertion sleeve of the coupling device in one planting stabilizer. In addition, the other planting stabilizer can be configured to be pivotably coupled to each other via a coupling shaft attached to the insertion sleeve of the coupling device in the other planting stabilizer. .
[0018]
In addition, the tree planting stabilization device includes a resistance plate device that is detachable in the vicinity of the tip of the arm, and is configured such that an adhesion member is provided on the resistance plate device. A bracket member that is detachably attached and extends in the extending direction of the arm, and an insertion sleeve provided in the vicinity of the tip of the bracket member, and is located between the adherend member and the insertion sleeve, and a connecting angle adjusting means In the state where one planting stabilization device to which the resistance plate device and the coupling device are attached and the other planting stabilization device to which the resistance plate device and the coupling device cannot be removed are brought close to each other, By attaching the arm of the other planting stabilizer to the insertion sleeve of the coupling device in the planting stabilizer, adjacent planting stabilizers can be connected to each other so as to be rotatable.
