Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening device used for constructing a tree support, for example, various torii-type supports.

[0002]

2. Description of the Related Art Conventionally, many gardeners and other craftsmen have planted garden trees and street trees in order to achieve greening of the environment.

[0003] The planted trees do not easily fall down due to strong winds or earthquakes which cause natural disasters, and need to be encouraged to grow. I have.

In many cases, a torii-shaped support is used as the support means. Depending on the size of the tree, for example, four standing supports and four horizontal supports are used for large trees. A well-shaped torii-shaped strut is applied when viewed from the plane where
A torii-shaped column is used in which one or two standing columns and one horizontal column are combined.

Here, a conventional torii-shaped support for a medium-sized tree will be described with reference to FIG. 10 which is a perspective view.

The torii type support is a structure for a medium-sized tree in which three upright supports 1, 2 and one horizontal support 3, which are synthetic wood or natural wood, are combined. One horizontal support 3 is incorporated between the vertical supports 1 and 2.

Next, a method of constructing the torii-shaped column having the above structure will be described.

After planting a desired medium-sized tree, three standing posts 1, 2 are cast around the tree, and the standing posts 1, 2
One of the horizontal supports 3 is sandwiched therebetween, and each of the vertical supports 1 and 2 is fastened to the one horizontal support 3 with a soft and thin iron wire 4a. Thereafter, the tree is wrapped with burlap or cedar bark, and fastened to the one horizontal support 3 with a lanyard via the burlap, cedar bark or the like to support the tree.

What is noticed in this construction method is that, in the fastening step using the iron wires 4a and 5a, the iron wire 4a is wound at least five times or more at the time of fastening at one place, while the wound iron wire 4a is The iron wire 5a for tensioning the looseness is wound many times, and when these iron wires 4a, 5a are randomly wound, each of the iron wires 4a is wound.
The iron wires 4a and 5a should be flush with each other in order to prevent the situation that the wires 5a and 5a themselves are loosened by the load of the strong wind or the action of the oscillating force at the time of the earthquake and the supporting force of the column is lowered. It is necessary to wind.

[0010] Further, a conventional torii-shaped support for a large tree,
Description will be given according to the example of FIG. 11 which is a partial perspective view.

This torii-shaped support is composed of four upright supports 1, 1 made of synthetic wood or natural wood, and four horizontal supports 3, 3, each of which has a bolt 7 and a nut 8 (dotted line portion). See
The trunk of a large tree (not shown) is located in a space surrounded by the horizontal columns 3, 3.

Next, a method of constructing the torii-shaped support having the above structure will be described.

After planting the desired large tree, four uprights 1, 1 are cast around the tree, and the uprights 1, 1
After inserting the two horizontal support columns 3 into each of them and making them orthogonal to each other, the bolts 7, 7 are further passed through the through holes 9, 9 formed in advance in the tree, and these bolts 7, 7 are nuts. Tighten by screwing 8 and 8. Thereafter, linen cloth or cedar bark is wound around the trunk outer peripheral surface of the large tree, and fastened to the horizontal support 3 with a lanyard via the linen cloth or cedar bark to support the tree.

[0014]

However, such a conventional method of fastening with a soft and thin iron wire in the prior art has a very high dependence on craftsmen who are construction specialists in the industry. This requires a reduction in construction time, and when planting trees on, for example, human roads laid on both sides of the road, attention must also be paid to the dangers caused by automobiles. Is said to be an unsuitable construction technology.

On the other hand, in recent years, construction specialists in this kind of industry have been declining, and although it is necessary to foster and increase construction specialists, the flow of human resources to other industries has been accelerated, and In reality, it is impossible for ordinary people to participate in the construction.

On the other hand, in a fastening system employing a combination tightening tool of the bolts 7, 7 and the nuts 8, 8, each of the struts 1,
The through holes 9 for the bolts 7, 7 are required in 1, 3, and 3, which involves the work of processing the through holes 9, and the through holes 9 are factors that reduce the shear stress of each of the columns 1, 3. Becomes

The present invention has been made in view of the above-mentioned problems of the prior art, and simplifies the process of fastening the pillars, which is a part of the method of constructing all the torii-shaped pillars, so that even ordinary people can use the method. It is an object of the present invention to provide a fastening device for a torii-type column that can participate in construction.

[0018]

According to the present invention, there is provided a wire rod and a tongue having a locking hole, and a gap between the tongues is provided. A torii-type column fastening device comprising a band serving as a curved portion and a tightening device, wherein each end of the wire rod which is bridged between columns of a contact portion between an upright column and a horizontal column is attached. The band is inserted into the opening of each tongue-shaped portion of the band positioned so that the curved portion is fitted to one outer periphery of the column, and is tightened by the tightening device to fasten the upright column and the horizontal column. It is characterized by the following.

In the present invention having such a structure, the method of winding the wire between the struts does not employ a method of winding the struts of the contact portion many times.
A single wire is tightened via a single band, and the columns can be easily and strongly fastened to each other.

According to a second aspect of the present invention, one wire rod having stud bolts fixed to both ends is provided, and a tongue having a locking hole is provided, and a curved portion is formed between the tongues. A torsion-type column fastening device comprising a band and a nut, wherein a stud bolt at each end of the wire rod, which is bridged between the columns at the contact portion between the upright column and the horizontal column, is provided at the column. And the stud bolts are tightened by screwing the nuts into the upright column and the horizontal column. Is characterized in that it is concluded.

In the present invention having such a horizontal structure, the method of winding one wire between the columns does not employ a method of winding the columns of the contact portion many times. A single wire is tightened via the band, and the columns can be easily and strongly fastened to each other, and the number of parts is small, so that cost reduction can be achieved.

Further, in claim 3 or 4, the bolt
The use of the connector is characterized in that the length of the wire is adjusted, so that the connection between the wires and the tightening of a single band can be enhanced, and the adjustment of the length of the wire can be simplified.

In addition, in the fifth aspect, the strut can be positioned and the tightening force can be reinforced by interposing the caul plate at the contact portion between the struts.

According to a sixth aspect of the present invention, the engaging hole formed in the tongue-shaped portion of the fastening device is a notch hole which is notched outward.

Further, in claim 7, one or both of the locking holes formed in the tongue portions on both sides of the fastening device are cutout holes cutout outward.
