Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to the structure of a tension wire support section in a farm.

In farms such as orchards, a large number of wire rods are strung vertically and horizontally in a criss-cross pattern, and the intersections of the strung wires are supported with supports. is used.

(Prior art) Regarding this type of tension frame, as a method of supporting the tension wire with supports, for example, Japanese Utility Model Publication No. 56-27704 discloses
Fit a cap onto the top end of the support column, insert the intersection of the tension wires into the cross groove formed on the top surface of the cap, and insert the cross section of the tension wire into the horizontal groove or horizontal hole formed on the side surface of the cap.
Insert a holding member such as a U-shaped pin laterally,
It has been proposed that this holding member prevents the intersection of tension wires from coming off the cross groove.

(Problem that the invention aims to solve) However, in this method, since the tension wire is stretched over a wide area at a relatively high position in the farm, one holding member is prepared one by one, and this is inserted into the horizontal groove or horizontal hole of the cap. The work of fitting them one by one is troublesome and inefficient, and also has the disadvantage that the holding member easily comes off from the horizontal groove.

(Means for Solving the Problems) The present invention eliminates the above-mentioned drawbacks in supporting tension wires in farms, and provides support for supporting tension wires by supporting struts efficiently and reliably at the intersections of tension wires with simple operations. It provides the structure of the section.

The present invention will be described below with reference to the drawings. In Fig. 1, 1 is a hot-dip galvanized steel pipe;
This is a support made of synthetic resin-coated steel pipe, synthetic resin pipe, etc., and a cap 2 is attached to the upper end of this support 1.
is fitted. On the top surface 21 of the cap 2,
Cross-shaped grooves 3, 3' are formed. Into these cross-shaped grooves 3, 3', tension wires 5, 5' made of galvanized steel wire, synthetic resin coated steel wire, steel cable wire, etc. are inserted vertically and crosswise. Cross-shaped groove 3,
3' may be formed deep enough that the tension wires 5, 5' completely sink into the groove as shown in the figure, or to such an extent that a part of the tension wires 5, 5' is exposed outside the groove. , may be formed shallowly.

Further, the top surface 21 of the cap 2 may be formed into a flat surface as shown in the drawing, may be rounded into a hemispherical shape, or may be formed into a truncated cone shape. The cap 2 is made of hot-dip galvanized steel, synthetic resin, etc., and the top surface 21 is preferably relatively thick.

Two hooks 4, 4' are provided protruding from both side surfaces 22, 22' of the cap 2. Hook 4,
4' is made from galvanized steel wire, synthetic resin, etc.
The lower ends 42, 42' of the hooks 4, 4' are welded to both side surfaces 22, 22' of the cap 2, respectively, and are fixedly integrated, and the downward hooks 41, 41' at the ends of the hooks 4, 4' are fixedly integrated. , both sides of the cap 22,
It protrudes so as to be located slightly away from 22' and approximately on the extension line of one of the grooves 3. Of the tension wires 5, 5' that intersect vertically, the upper tension wire 5 is hooked to the hook portions 41, 41' of the hooks 4, 4'.

(Function) Connect the upper tension wire 5 to the hooks 41, 4 of the hooks 4, 4'.
1', first insert the intersection of the pre-strung tension wires 5, 5' into the cross-shaped grooves 3, 3' of the cap 2 fitted to the support column 1. , or when stretching the tension wires, insert the tension wires 5 and 5' one by one in a vertically crossing manner. As a result, movement of the tension wire is prevented by the concave groove of the cap.
After that, pull the upper tension wire 5 downward by hand at a point slightly away from the groove 3 and the hooks 4, 4'.
Release your hands at a position below the hooks 41, 41' of the hooks 4, 4'. Then, the upper tension wire 5 tries to restore upward due to the tension, and is securely hooked to the downward hook portions 41, 41' of the hooks 4, 4'.

(Effects of the invention) As mentioned above, in the present invention, hooks are provided protruding from both sides of the cap fitted to the upper end of the column.
Of the upper and lower cross-shaped tension wires inserted into the cross-shaped groove on the top of the cap, the upper tension wire is hooked to the hook of the hook. The tension wires are also securely fixed in the cross-shaped grooves of the cap, and the crossing portions of the tension wires are prevented from coming off the grooves.

In addition, since the hook of the hook is located approximately on the extension line of one of the grooves, the work of hooking the upper tension wire inserted into the groove of the hook to the hook of the hook is difficult. This can be done by simply pulling the tension wire downward from the hook of the hook by hand, and as in the conventional method described above, each holding member is prepared one by one.
There is no need for the troublesome work of fitting these wires one by one into the slots of the cap, and it is possible to efficiently support the farm's tension lines.

Furthermore, the hooks of the two hooks are fixed and integrated and protrude slightly apart from both sides of the cap, making it easy to use when stringing wire for hanging fruit tree branches or hanging balls. By using the center part of the hook that is away from the cap, it is possible to pass a wire rod through the center part of the hook and hang it there.It can also be used as a support for hanging from a branch or hanging a ball, and the hook has a fairly strong downward direction. Even if a load is applied, since the hook portion of the hook is hooked to the tension wire, there is an advantage that the load is supported by the tension wire and the hook is prevented from bending downward.
