Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a support that is effective in preventing trees from falling during the early stages of planting.

[Prior Art and its Issues] Conventionally, timber logs have been widely used as a measure to prevent trees from falling during the early stages of planting. That is, logs are placed around the tree, further logs are placed horizontally between the upper ends of the logs, and the tree is connected and supported by fiber ropes or the like. However, in order to increase the collapse resistance of trees, the effect cannot be obtained unless long logs are driven deep into the ground, which poses the problem of increased construction labor. There were also problems with tree support, such as the fact that this type of log support structure spoiled the aesthetics.

In recent years, as a means to solve such problems,
Support structures made of metal pipes and the like have been developed which are provided with easy-to-drive foundation piles separately from the support supports. The connection structure between the columns and support rods that make up this column structure is as follows:
A joint member having a semicircular planar shape and a curvature of approximately the same diameter as the outer diameter of the support rod is attached to the end of the support rod, and this joint member is brought into contact with the outer surface of the support rod, and both ends are secured with bolts and nuts. It is designed to be combined.

According to this connection structure between the two, the connection between the two relies entirely on bolts and nuts, and the connection between the two tends to loosen due to the shaking of the tree, so a large knotting moment cannot be obtained, and the tree is not easily moved by wind. There were problems such as insufficient absorption of vibration and looseness in the joint between the two, which eventually led to loosening of bolts and accidents resulting in them falling off.

The purpose of the present invention was made in view of these circumstances, and is to solve the problems of the prior art by simple yet rational means, and to integrate and connect the column and the support rod tightly without loosening. This aims to provide a tree support structure that prevents bolts from loosening, has a large knotting moment, and has a strong truss structure.

[Means for Solving the Problems] The structure of the present invention that solves the problems of the prior art is such that one end of the support rod can be attached and detached in a direction substantially perpendicular to the upper end of a support made of metal pipe material or the like with a foundation pile provided at the lower end. In a tree support structure consisting of an interlocking structure of the support rod and the support rod, the support rod and the tree are connected with a fiber rope or the like to support a tree in the early stage of planting. A joint member 6 having an outward U-shaped planar shape is provided at one end, and the width between the inner surfaces of the left and right sides 6a constituting the joint member 6 is formed to be slightly smaller than the outer diameter of the support. A bolt is inserted into the intermediate side 6b of the support column in the diametrical direction, and a tightening nut is screwed onto the end of the bolt.
The tip is pressed against the outer surface of the support.

[Example] The details of the embodiments will be explained with reference to the drawings.

As shown in Figure 2, the details will be described later.

Reference numeral 4 denotes a support rod having a planar shape of about 1/3 arc and made of metal pipe material, which is attached between the upper ends of each of the above-mentioned pillars 1. These three support rods 4 form a circular support structure. It is designed so that you can get it.

In addition, at the center of each support rod 4 on the concave side,
A fastening hook 5 for fastening a fiber rope (not shown) is provided in each case.

At the end of each of the support rods 4, as shown in FIGS. 3a and 3b, a joint member 6 having an outwardly U-shaped planar shape is provided. Then, the width l between the inner surfaces of the left and right sides 6a constituting the joint member 6 is formed to be slightly smaller than the outer diameter R of the support column 1. In addition, the joint member 6
A hole 7 is provided in the center of the intermediate side 6a of the
A hole 8 is also provided in the diametrical direction of the column 1 to which this hole 7 corresponds, a bolt 9 is inserted into both holes 7 and 8, and a tightening nut is attached to the end of the bolt 9 that protrudes outward from the joint member 6 on the opposite side. 10. This state is shown in Figure 3a.
is shown. In this state, the ends 6a of both sides of both joint members 6 touch the outer surface of the support column 1,
There is a slight gap between the intermediate side 6b of each joint member 6 and the support column 1. In this state, when the tightening nut 10 is tightened until the above-mentioned gap disappears or until the inner surface of the intermediate side 6b approaches the support 1, both sides 6a of the joint member 6 are tightened as shown in Fig. 3b. It is expanded along the outer surface, and due to the spring back moment of the both sides 6a, the both sides 6 of the joint member 6 are expanded.
a strongly presses into engagement with the outer surface of the support column 1. In this way, a column structure A having three columns as shown in FIGS. 1 and 2 is obtained.

Next, to explain the method of burying each pillar 1 of the pillar structure A, a hole deep enough to embed the resistor 2 provided at the lower end of the pillar 1 is dug in the ring, and the pillar 1 is placed in the bottom of this hole. After installing the resistor 2, the angle of the pillar 1 is determined. Next, insert the foundation pile 3 parallel to the resistor 2 support 1, drive it into the soil with a driving tool such as a hammer, and fill the hole with soil to strengthen the support 1.
That is, it is fixed so that it does not move in the front, back, left, and right directions, and in the up and down directions. This pouring method can be applied as is to other embodiments to be described later, so it will be referred to in each embodiment.

Since it is the same as , the explanation is omitted and the same members are represented by the same reference numerals.

Next, referring to FIG. 12, the connection structure between the resistor 2 provided at the lower end of the column 1 and the foundation pile 3 will be explained. One side of a resistance plate 11 having a rectangular planar shape perpendicular to the axial direction of the column 1 is fixed to the lower end of the column 1. On the upper surface of this resistance plate 11, a resistance plate having an elongated U-shape in plan view and having a curved portion at one end protrude outward from the edge of the resistance plate 11 to form an insertion cylinder portion 12a for the foundation pile 3 is provided.
