DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supporting and supporting trees, and a fixing tool for root mortars and supporting tools for use in the method for supporting and supporting trees. More specifically, the present invention relates to a large-scale development area, a city planning area, and an exposition. Supporting method of trees to support and support artificially planted trees at venues, parks, pavements, etc., and root mortars used to fix root mortars in the method of supporting and supporting trees The present invention relates to a fixing tool and a support construction tool comprising the fixing tool for a root pot and a tightening belt.

[0002]

2. Description of the Related Art Conventionally, as a method of supporting a tree of this type, there is a method of supporting a tree described in Japanese Patent Application Laid-Open No. 9-56270.

[0003] That is, as shown in FIGS. 23 and 24, this supporting construction method stores a root pot 21 in a planting hole 18 formed in advance on the ground and places it at four places on the shoulder of the root pot 21. Pat 31,
, And a resistance pile 32 is connected to the pads 31, and the tree is supported and fixed by driving the resistance pile 32 into the bottom wall surface 19 of the planting hole 18.

Further, a string 33 is used in place of the above-mentioned resistance pile as shown in FIGS. 25 and 26, and the string 33 is put on a pad.
At the same time as passing through the upper surface of the root material 31, the end of the string material 33 is hooked on a root pot mounting device (not shown) laid in advance on the lower surface of the root pot and supported by the tightening force of the string material 33. There is also a method of fixing.

However, in such a conventional method, since the driving force of the resistance pile 32 and the tightening force of the string material 33 are applied independently to each place where each pad 31 is installed, the strength is large in one place. Force is applied in a concentrated manner, and as a result, the driving force of the resistance pile 32 and the tightening force of the string material 33 are
, The pad 31 itself may bite into the root bowl 21, and in some cases, the root bowl 21 may be broken.

In order to solve this problem, it is conceivable to increase the area of the pat 31 to disperse the force applied to the pat 31. However, since the conventional pat has a plate shape, it is difficult to increase the area. There was a problem that the growth of roots was hindered, and the area could not be increased unnecessarily.

However, in this conventional method, since the force acting on the pad is applied straight downward, it is important to fix the root pot by increasing the pad and pressing down strongly. Therefore, it was also fatal that the area of the putt was restricted from the viewpoint of root growth.

Further, such a conventional supporting construction method is as follows.
Although it can support the construction of relatively short trees that are planted in parks, pavements, etc., it is suitable for planting zelkova and other high trees that are planted in large areas in large-scale development areas, urban planning areas, etc. Cannot always respond sufficiently.

That is, in large-scale development areas, city planning areas, etc., it is considered that zelkova trees such as zelkova, which are actually used for windbreak forests and the like and are known to form a characteristic landscape, are used. However, in the case of zelkova and other high trees,
Tilting the trees by the wind is dangerous, and even a slight angle of tilt is basically unacceptable.

Also, once tilted, it is difficult to correct because it is a tree.

In this case, the point is how much the initial movement and initial inclination of the tree due to the wind can be prevented.

[0012] In order to solve these problems, it is necessary to ensure that the root mortar is fixed and to prevent the root from being tilted by the wind.

The present invention has been made in view of the above points, and can prevent damage or cracking of a root mortar, can minimize initial movement of a tree by receiving wind, and can prevent the initial movement of a tree by shaking. Supporting tree construction that can correct tilting of trees and misalignment of root mortars, has good workability, and can be used especially in places where a large number of trees such as zelkova are planted over a wide area. It is an object of the present invention to provide a method, a fixing tool for root mortar, and a support construction tool used in the method.

[0014]

[0021]

Embodiments of the present invention will be described below with reference to the drawings.

First, an embodiment of a root mortar fixture will be described.

In FIGS. 1 to 3, reference numeral 1 denotes an iron mortar fixture, which is a root mortar upper surface mounting portion 2 which is installed on the upper surface of the root mortar.
And a supporting member 5 connected to the pressing member 4, a pressing member 4 for pressing the root pot upper surface mounting portion 2, and a supporting member 5 connected to the pressing member 4. .

The root mortar upper surface installation portion 2 is assembled such that iron linear members 6 are obliquely intersecting with each other, and a substantially rectangular connecting rod 7 is provided at a lower portion thereof.

The lateral mounting portion 3 has a structure in which three lateral rods 9, 8 are fixedly attached to two vertical rods 8, 8 on both sides. The hooks 10, 10 of the vertical rod 8 are engaged with each other, and are rotatably supported by the root pot upper surface installation part 2.

The root pot side installation part 3 includes a palm mat 11
Is installed.

The holding member 4 is formed in a substantially rectangular frame shape as a whole, and its upper horizontal frame 4a acts as a spring when pressing the root pot upper surface installation portion 2, and both side frames 4b, 4b Acts as a lever when pressing the pot upper surface installation part 2, and serves as a lower horizontal frame 4c.
Is a fulcrum of rotation.

The support member 5 is formed in a substantially C-shape on the front, and the upper hook portions 12, 12 are engaged with the lower horizontal frame 4c of the pressing member 4. In addition, the support member 5 is fixed to the root pot side installation part 3 by welding.

At the lower end of the support member 5, a mounting portion 13 for mounting to a pedestal described later is formed.

The mounting portion 13 is formed in a substantially square shape, and has a hole 14 formed therein.

In FIG. 4, reference numeral 15 denotes a pedestal for mounting the support member 5, and a corner portion 4 of a square outer frame 16 is provided.
The support rods 17,... Are respectively constructed at the locations.

Although not shown in detail, the outer frame 16 is formed in a so-called L angle, that is, a substantially L shape.

Next, the fixture 1 for the root mortar and the base 15
An embodiment of a supporting construction method for supporting and constructing a tree using the above will be described.

First, as shown in FIG. 5 and FIG.
The pedestal 15 is placed on the bottom surface 19 of the.

Next, as shown in FIG. 7, soil (artificial soil) 20 is sprayed on a portion surrounded by the pedestal 15 on the bottom surface 19 of the planting hole 18, and as shown in FIGS. The root pot 21 on which the tree 22 is erected is placed.

Next, the fixture 1 for a root pot of the above embodiment is installed in a root pot 21.

More specifically, as shown in FIG. 9, the hole 14 of the mounting portion 13 of the support member 5 of the root mortar fixture 1 and the hole 23 of the support rod 17 of the pedestal 15 communicate with each other. The mounting portion 13 of the supporting member 5 of the pot fixing device 1 is brought into contact with the supporting rod 17 of the pedestal 15, and in this state, the bolts 24 are inserted into the holes 14 and 23 communicating with each other. Screw it. In this case, the mounting portions 13, 13 of the supporting members 5, 5 of the adjacent root mortar fixtures 1, 1 are mounted in an overlapping manner as shown in FIG.

As a result, as shown in FIG. 10, the supporting member 5 is maintained in the vertical direction, and the fixture 1 for the root pot is erected.

In this manner, a total of eight root fixtures 1
Are attached around the root pot 21 as shown in FIG.

Next, as shown in FIG. 12, a substantially ring-shaped trunk belt 26 is installed around the root of the tree 22.

Thereafter, as shown in FIGS. 13 and 14, a plate-shaped belt-like tightening belt 27 is connected to and attached to the trunk belt 26 and the fixing device 1 for the root pot.

More specifically, as shown in FIGS. 13 to 16, one tightening belt 27 is composed of a total of eight winches 28 attached to a trunk belt 26, and eight root mortars. Of the holding member 4 of the fixing device 1 and the lower horizontal frame 4c.
Holder 4 and two winches of root mortar fixture 1
28 and 28 form a substantially V-shape, and are looped so that eight V-shapes are formed as a whole.

Then, a total of eight winches 28,... Are individually tightened in a state where the tightening belt 27 is wound around the whole, thereby generating a tightening force on the tightening belt 27.

In this case, when a tightening force is generated in the tightening belt 27, the tightening belt 27 presses the pressing member 4 of the root mortar fixture 1 in the direction of arrow A in FIG. The lateral frame 4a functions as a spring, and the side frames 4b, 4b on both sides function as levers, and the root mortar 21 is pressed down by the interaction between the two.

More specifically, the force of the root basin 21 to tilt due to the tree swaying due to wind or the like is first transmitted to the upper horizontal frame 4a functioning as a spring.

Since the upper horizontal frame 4a is strongly tightened by the tightening belt 27, the upper horizontal frame 4a distributes its force to the right and left as shown in the direction of arrow B in FIG. By the action, as shown in the direction of arrow C, the entire upper part of the root pot 21 is pressed down with a strong force.

Since the root mortar fixture 1 facing the root mortar fixture 1 acting as described above is also integrated by the tightening belt 27, the same phenomenon occurs.

Conversely, when the root mortar 21 is lowered, the spring of the upper horizontal frame 4a acts so as not to form a gap, and tries to strongly press the root mortar.

In this case, for example, as shown in FIG. 17, if the wind blows in the direction of arrow D, the V-shaped portion 27a of the tightening belt 27 located in the direction opposite to the wind has the V-shaped portion. Winches 28, 28 on both sides of part 27a
From the positions A, A to (A in the direction of arrow E) from the positions A, A to the position A 'looped around the lower horizontal frame 4c of the pressing member 4.

In the other V-shaped portions 27b, 27c and 27d, tension acts obliquely rearward in a direction opposite to the wind direction.

That is, as shown in FIG. 17 and FIG.
The tension acts on the positions B and B of the V-shaped portion 27b toward the diagonally rearward B '(in the direction of the arrow), and on the positions C and C of the V-shaped portion 27c, the diagonally rearward C' (in the direction of the arrow G). Tension acts on the positions D and D of the V-shaped portion 27d toward the diagonally rearward direction D '(in the direction of the arrow C).

Accordingly, since the tightening belt 27 is pulled obliquely rearward from each point, all the forces are dispersed, and a strong force is not applied to one point.

As described above, according to the present embodiment, it is possible to realize a structure capable of pulling the action points (A, B, C, D, etc. in FIG. 17) requiring the most wind pressure from the lower rear portion. It exerts great resistance, and as a result, the initial movement and initial inclination of the tree due to the wind are prevented as much as possible.

In this embodiment, the tree sway due to the wind is tightened by the action of the upper horizontal frame 4a of the holding member 4 as a spring and the action of the side frames 4b, 4b of the holding member 4 as levers. It is preferably transmitted to the belt 27, which receives the whole structure of the eight fastening belts 27 having a V-shape and the eight inverted V-shaped support members 5 of the root mortar fixture 1.
It has a function to correct the position shift and deformation.

Further, the root pot side installation section 3 has a structure in which three horizontal rods 9, 8 are fixedly attached to two vertical rods 8, 8 on both sides, and has a structure having many spaces. However, since the palm mat 11 is attached, the initial resistance area is increased, and the effect of the root pot side installation part 3 contacting the side face of the root pot 21 is not impaired.

On the other hand, the palm mat 11 can be decomposed in about two years, and when the root of the tree grows and extends to the outside of the side of the root pot, the palm mat 11 is decomposed.

Therefore, the growing roots are located in the root pot side installation section 3.
Extend through relatively large gaps between the vertical rods 8, 8 and the horizontal rods 9,... And do not hinder their growth.

In the above embodiment, the root mortar fixture 1 having the support member 5 formed in a substantially U-shape on the front is used as the root mortar 21.
Are arranged in eight places around the vehicle, and one tightening belt 27 is attached to the trunk belt 26 for a total of eight winches.
.. And the lower frame 4c of the holding member 4 of the root mortar fixture 1 at eight locations, and the supporting member 4 of the root mortar fixture 1 and the two winches 28, 28 And a substantially V-shape is formed, and the root mortar 21 is fixed by being wrapped so as to form eight V-shapes as a whole, but the means for fixing the root mortar 21 is not limited to this. .

For example, as shown in FIG. 19, a support member 5 made of an iron wire rope is wound around an inverted V-shape,
The upper end 5a, which is the starting point of the branching of the two support members 5,5, is attached to the trunk belt 26 via a stopper 28b, and the lower end 5b, 5b of each of the two support members 5,5 is attached to the pedestal 15. By attaching, the root mortar 21 can be fixed.

Also in this case, the pair of support members 5
5 are arranged obliquely so as to be separated from each other downward.

In the embodiment shown in FIG. 19, similarly to the above-described embodiment, the root pot upper surface installation portion 2 is assembled so that the linear bodies cross diagonally, and three vertical rods are provided on the two vertical rods on both sides. Is fixed to the root pot top surface mounting part 2 and the rotatable root pot side mounting part 3 which is fixed to the root pot fixing means 1 between the support member 5 and the root pot 21. It is interposed in.

Further, as shown in FIG. 20, the supporting member 5 made of a wire rope is directly
It is also possible to install at 21.

Further, as shown in FIG. 21, it is also possible to provide such that the intersections of the support members 5 made of wire ropes exist at a plurality of places around the root mortar.

In this case, as a result, the support member 5
It is wrapped around the root bowl 21 in a substantially net shape.

Further, as shown in FIG. 22, two trunk belts 26 are provided, and each trunk belt 26 has four pairs of support members 5,
5 can be attached.

Also in this embodiment, a support member 5 composed of a wire rope is provided, and the support member 5 is connected to the trunk belt via a fastener 28a which is tightened with bolts and nuts.
Connected to 26.

Further, a fixing device 1 for a root pot in which rods are juxtaposed in the lateral direction is interposed between the root pot and the supporting member 5 so as to be installed only on the upper surface of the root pot.

Although not shown in detail in FIG. 22, the pair of support members 5, 5 are also obliquely arranged on the side surface of the root pot so as to be separated from each other downward.

In the embodiment shown in FIGS. 20 and 21, the wire rope itself is the fixing tool 1 for the root mortar, and is also used as the tightening belt 27.

Accordingly, the fixing tool 1 for the root mortar and the tightening belt 27
Is not an essential condition of the present invention.

Further, in the above embodiment, the root pot side installation portion 3 includes two vertical rods 8 on both sides and three horizontal rods 9,.
Has a preferable effect of not inhibiting root growth, but such a configuration is not an essential condition of the present invention.

Accordingly, a net-like or plate-like thing is also included in the scope of the present invention, but in practice, it is empirically found that the root extends laterally from the position of the side of the mortar near the shoulder. In consideration of this point, it is desirable that the net has at least a net-like shape. Particularly, in the case of a thick tree such as zelkova, the roots are thick, and the root may not pass through the net-like shape. Vertical rods 8, 8 on both sides like form
In addition, a structure in which three horizontal rods 9,... Are fixed is preferable.

Further, in the present embodiment, since the palm mat 11 was attached to the root pot side installation portion 3, the above-described preferable effects were obtained.
Is not an essential condition of the present invention.

Further, the structure of the root pot upper surface installation section 2 is not limited to the above embodiment.

Further, in the above embodiment, the holding member 4
Is formed in a substantially rectangular frame shape, the upper horizontal frame 4a acts as a spring when pressing the root pot top surface installation part 2, and the side frames 4b, 4b on both sides press the root pot top surface installation part 2. In this case, the lower horizontal frame 4c functions as a lever, and the lower horizontal frame 4c is configured to be a fulcrum of rotation. However, the structure of the pressing member 4 is not limited to this.

Further, in this embodiment, a rectangular outer frame is used.
The pedestal 15 is constructed in such a manner that the supporting rods 17,... Are erected at four corner portions of 16 respectively, but the shape of the pedestal 15 is not limited to this, and the shape is not limited.

Furthermore, in this embodiment, the bottom wall surface of the planting hole 18
By mounting the pedestal 15 on the base 19 and attaching the mounting portion 13 of the support leg 5 to the pedestal 15, the root mortar fixture 1 is installed on the side wall surface of the root mortar. It is not limited.

Instead of the pedestal 15 as in the above embodiment, a root pot mounting device for mounting a root pot is provided on the bottom wall surface of the planting hole 18.
It is also possible to support and construct the root mortar by placing the root mortar 21 on the root mortar mounting device and fixing the tightening belt 27 to the root mortar mounting device as described above. It is.

Further, for example, a means may be used in which a wire rope as described above is wound around the root bowl 21, an anchor is connected to the wire rope, and the anchor is driven into the ground to generate a tightening force. Good.

The shape of the tightening belt 27 is not limited to the plate belt shape as in the above embodiment, but may be a thin string shape.

The material of the tightening belt 27 is also synthetic resin,
Any kind of natural fiber or the like can be used.

Further, in the above-described embodiment, a tightening force is applied to the belt by tightening the winch 28, but the means for generating the tightening force to the belt is not limited to the winch 28. For example, it is also possible to use a fastener 28a that is tightened with bolts and nuts as in the embodiment of FIG.

Further, in the above-described embodiment, an iron-made fixture 1 is used. However, the material of the fixture 1 is not limited to iron, and other metals may be used. Alternatively, a material other than metal may be used.

Further, in the above embodiment, the case where the present invention is applied to the construction method of supporting trees underground has been described.
The present invention is not limited to this, and can be applied to a construction method in a roof garden.

[0085]

As described above, according to the present invention, a plurality of pairs of support members are arranged obliquely along the side of a root pot of a tree, or are arranged downward, so that the applied force is dispersed. Is a method of supporting and constructing a tree by arranging a plurality of fixtures for root pots having a pair of support members obliquely arranged so as to be separated from each other along the side of the root pot of the tree. , The force acting on the root mortar, unlike the conventional, is not applied independently for each place where the pat or the string material is installed, that is, the strong force is not concentrated and applied to one place In addition, the pair of support members disposed obliquely so as to be separated from each other downwardly is preferably dispersed, and the initial movement and the initial inclination of the tree due to the wind are prevented as much as possible.

Further, unlike the conventional case, the tightening force of the string material acts on the pad, so that the pad itself does not bite into the root mortar and the root mortar does not break.

In particular, the tightening belt is wrapped around the root mortar so as to form a plurality of substantially V shapes toward the above-mentioned root mortar fixture, and the tightening belt is hooked on the root mortar fixture. When the tree is supported and constructed by this, tension is generated in the substantially V-shaped portion of the tightening belt in the direction opposite to the direction in which the wind blows, and tension acts in an oblique direction along the V-shaped portion, and from the tightening belt. As described above, the force is transmitted to the pair of support members obliquely arranged so as to be separated from each other in the downward direction, and the tightening belt is pulled obliquely rearward from the connection point with the root mortar fixture. For this reason, the distribution of the force applied to the root mortar is more suitably performed, and there is an effect that it is possible to more suitably prevent a strong force from being applied to one point.

As described above, not only the initial movement and swaying or initial inclination of the tree due to the wind can be suitably prevented, but also the positional displacement and deformation of the root can be suitably corrected.

Further, since such initial movement of the tree and displacement of the root pot are prevented, the workability is significantly improved as compared with the prior art.

As described above, in the present invention, it is possible to prevent the initial movement and tilting of trees, especially zelkova trees, etc. due to the wind, and also to correct the displacement and deformation of the root mortar by absorbing the shaking. The workability is good, and it is possible to provide a construction method suitable for supporting a large number of tall trees in large-scale development areas and urban planning areas without causing damage or cracking of the root mortar. It has an effect.

Further, when the lower ends of the pair of support members are fixed, the support members do not move along the root mortar or are not displaced.
Tightening force and the like can be reliably applied.
