Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a staying structure for a support wire that supports a rod-shaped body such as a tree.

(Prior Art) FIG. 3 shows a conventional support structure in which a rod-shaped body, particularly a tree, is supported from three directions by a support wire made of a filament such as an iron wire or a wire rope. The lines are likewise separately anchored to the ground. In the figure,
A tree protective material 2 is wound around a tree 1, one end of a supporting wire 3 is wound on the outside thereof, and the folded back end is fixed to the supporting wire 3 with a wire clip 4, and the other end of the supporting wire 3 is a turnbuckle. 5 and a shackle 6 are connected to an anchor 7 buried in the ground by applying tension. In the figure, details are shown only for one support line, but the same applies to the other two support lines. Further, FIG. 4 shows an example of a main part of holding the support wire 3 to a tree. In the figure, reference numeral 1 denotes a cross section of a tree, in which a supporting wire 3 is wound on the outer side of a tree protecting material 2, and the folded end portion is connected to the supporting wire 3 with bolts and nuts of a wire clip 4. It is fastened and fixed. FIG. 5 shows a main part of another example of retaining the support wire 3 to a tree. The tip of the support wire 3 is a winding formed of a loop-shaped part 8 and a winding part 9 without being wound around the tree. Attach the loop-shaped part 8 of the attached grip 10 to the tree and the winding part 9
The support line 3 is fixed by. In addition, although the above has mentioned the example of supporting with three supporting wires, it may support with four supporting wires, and in this case, the same supporting structure as in the case of the above three wires is taken. There is.

(Problems to be solved by the invention) In the retracting structure as shown in FIG.
Moreover, the bolt of the wire clip 4 may be loosened due to the aging creep of the support wire, and the support wire may come off unless the bolt is retightened. Further, in the retracting structure as shown in Fig. 5, a winding grip having a loop-shaped portion having a loop size corresponding to the size of a tree is required, and many types of winding wire can be used for one type of support wire. It is necessary to prepare an attached grip, which is troublesome.

(Means for Solving the Problem) The present invention has been made in view of the above-mentioned actual circumstances,
The anchoring structure of the other end of the support wire fixed to the anchor buried in the ground through the turnbuckle and the shackle is improved.

That is, when supporting with three support wires, the other end of one support wire is wrapped around a rod-shaped body such as a tree, and the other end of the other support wire is wrapped around the folded end. An end connected by a winding grip, and the other end of the remaining one supporting wire is connected to the winding portion of the supporting wire wound on the rod-shaped body through the winding grip. It is a structure.

In addition, when supporting with four support wires, the four support wires are made up of two sets with two adjacent support wires as one set,
The other end of one support wire of each set is wound around the rod-shaped body, and the other end of another support wire of the same set is connected to the folded end with a winding grip. It is a structure.

According to the pulling structure as described above, since the support wire itself is wound around the rod-shaped body, it can be applied to the rod-shaped body of any size, and since the winding grip is used, the construction is easy and the wire clip is used. It does not cause loosening due to aging such as bolt tightening. Further, it is not necessary to prepare winding grips of various sizes.

It is also possible to construct two continuous wires in the case of three support and two wires of each set in the case of four support, but the rod-shaped body is high and the supporting point is high. When it is necessary, a supporting line having a length equal to or greater than the height of the rod must be rotated around the rod, which is troublesome.

(Embodiment) FIGS. 1 and 2 are explanatory views of the main part showing an embodiment of a support wire anchoring structure in the case where the rod-shaped body is a tree according to the present invention, and FIG. 1 shows a case where three rods are supported. , FIG. 2 shows the case of four supports. In FIG. 1, 1 is a cross section of a tree, 2 is a tree protection material, and a support wire 3A is wound around the tree 1 from the outside,
The folded back end 3A-1 and the end 3B-1 of the support wire 3B are connected by a winding grip 11, and the winding portion 3A-2 of the support wire 3A and the end of the support wire 3C are further wound. Connected by a grip 12, the support wire 3A, the support wire 3B, and the support wire 3C are respectively retained by applying tension by rotating a bolt of a turnbuckle.

In Fig. 2, the support lines 3D and 3E, and 3F and 3G are one set of support lines, and each set supports from the opposite direction. As in the case of Fig. 1, 1 is a tree cross section, 2 Is a tree protection material. (A) In the figure, a support wire 3D is wound around the tree 1 from the outside of the tree protection material 2 and the folded back end 3D-1
And the end 3E-1 of the support wire 3E are connected by the wrapping grip 12,
The support line 3F is wound around the tree 1 from the outside of the tree protection material 2 as shown in the figure (b) in the vicinity of the winding part of the support line 3D, and the folded back end 3F-1 and the end of the support line 3G. Part 3G-1 wrapped grip
Connected by 13, each support wire is retained by applying tension by turning a bolt of a turnbuckle.

In the case of supporting using a supporting wire of a number other than three or four, the same can be done by applying the case of FIG. 1 and the case of FIG.

(Effects of the Invention) If the rod-like body supporting wire anchoring structure of the present invention is used, the number of types of wrapping grips can be reduced regardless of the size of the rod-shaped body, the construction is simple and the work efficiency is improved, The looseness of the support line due to changes is also eliminated.
