Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope support fitting and a rope support suitable for mounting a rope (fiber rope, wire rope, or the like) on a support, or for mounting a net. The present invention relates to a method and a net stretching method.

[0002]

2. Description of the Related Art Conventionally, when a rope or a net is attached to a support and stretched, a plurality of ropes such as U-bolts and nuts are usually mounted on a support built by driving at appropriate intervals. Attached with metal fittings, the end of the rope is connected to the support of the terminal with appropriate metal fittings, this rope is tensioned moderately with a turnbuckle etc. I have. In addition, the upper edge of the net and the rope attached to the upper edge are attached to the support with similar metal fittings, and the end of the rope is connected to the support of the terminal with appropriate metal fittings. It is constructed as a net fence or net enclosure fence with a tensioned structure.

[0003]

Conventionally, when a rope or a net is mounted on a support and stretched, a rope or a rope with a net is mounted on the support with a bracket such as a U-bolt or a nut as described above. Since the rope is locally supported by this bracket, the rope is easily damaged locally at the support. Decrease. In addition, there is a problem in that when the rope or the net is stretched or removed, a troublesome work of attaching and detaching a large number of mounting brackets to and from each support is required.

SUMMARY OF THE INVENTION The present invention has been developed to solve the above-mentioned problem. The object of the present invention is to detachably insert a rope into left and right spiral portions of a column mounting bracket, and attach the rope to the column. Locking or inserting the mounting part into the mounting bracket on the pillar side makes it easy to stretch and remove ropes and nets, etc. It is another object of the present invention to provide a rope mounting bracket, a method of stretching a rope, and a method of stretching a net, which are improved in stretching performance, reliability and durability as well as removal performance.

[0005]

SUMMARY OF THE INVENTION The present invention provides a U-shaped mounting portion which is formed at the center of a rigid wire rod and is engaged or inserted into a mounting bracket on the side of a support, and two legs of the mounting portion. The left and right spiral parts are characterized in that they are connected to each other and formed into a spiral pitch longer than at least the diameter of the rope, and left and right spiral parts through which the rope is removably inserted. The rope is easily inserted into and detached easily, and the rope is easily attached to the column by attaching or fitting the mounting part to the mounting bracket on the side of the column. The cushioning support over an appropriate length effectively reduces the local concentrated load of the rope at the mounting support, and facilitates removal, removal and re-stretching of the rope.

[0006] After the rope is sequentially inserted into the left and right helical portions of the column mounting bracket from the adjacent wire rods and inserted through the column mounting bracket, the column mounting bracket is used to mount the column. After engaging with the head of the mounting bracket provided on the support side, or inserting the mounting part into the head of the mounting bracket on the support side,
The rope is easily inserted and inserted into the left and right helical parts from the adjacent wire rods, so that the rope can be easily mounted and stretched on the support, making it easy to remove, remove and re-stretch the rope. .

In the above-described rope tensioning, the bolt portion of the mounting bracket is inserted into and attached to the column, and the mounting portion of the column mounting bracket is locked or inserted into the head of the mounting bracket. By tightening the bolt part with a nut and pulling the head of the mounting bracket toward the column, the head is locked or fitted to the head of the mounting bracket to prevent the mounting part of the column mounting bracket from detaching and close to the column. The rope mounting performance and reliability have been further improved by arranging the pole mounting bracket so that it can be easily removed and removed from the head of the mounting bracket.

Further, using the above-mentioned mounting bracket, the upper edge of the net and the rope of the upper edge are sequentially inserted into the left and right spiral portions of the mounting column from the space between adjacent wires. After insertion, the mounting part of the column mounting bracket is locked to the head of the mounting bracket provided on the column side, or this mounting part is inserted into the head of the column-side mounting bracket, and then left and right spiral By sequentially inserting and inserting a rope between adjacent wire rods in the portion, the net can be easily attached to and stretched on the column, and the removal and removal and re-stretching of the net can be facilitated.

In the case where a net is attached to the column and the column is stretched, preferably, the mounting bracket 3 of the head 3c and the mounting bracket 4 of the head 4b are fixed to the column 2 in advance as shown in FIG. Using the mounting bracket 1, the fiber net 6 is tied to the upper edge and the lower edge in the case of a fiber net, and the fiber rope 6 is attached by being inserted, and the wire mesh is tied to the upper edge and the lower edge. A rope 6 such as a cable or a wire rope, which is easy to bend and is attached by insertion or the like, is attached to the support 2 and stretched. That is, the rope 6 at the upper edge is inserted into the left and right spiral portions 1b of the mounting bracket 1 as described above, and the mounting portion 1a of the mounting column is locked to the head 3c of the mounting bracket 3. By doing so, the rope can be easily mounted on the column 2, and the rope 6 at the lower edge can be inserted into the head 4 b of the mounting bracket 4 by inserting the mounting portion 1 a of the column mounting bracket 1 as described above. After that, the rope 6 is inserted into both the spiral portions 1b of the pole mounting bracket, the rope is easily mounted on the column 2, and the net 7 can be easily mounted on the column 2 with both ropes 6. The rope 6 at the upper edge is easily removed from the column 2 by releasing the lock, and the rope 6 at the lower edge can be easily removed from the two spiral portions 1b of the bracket 1 for mounting the column. It is easy to remove 7 and re-install.

Nets 7 are also provided on the pillars 2 which are erected at intervals.
Attach the rope 6 at the upper edge and the lower edge in the same manner
Then, the ends of the nets 7 are appropriately tensioned, connected and stretched by appropriate means (not shown), and the nets 7 are used as net fences 20 or as net fences in a ranch F or the like as shown in FIG. It can be easily constructed. Further, in the net stretching, the mounting bracket 3 for the heads 3a and 3b and the mounting bracket 4 for the head 4a can be applied as necessary. Further, when the rope 6 inserted into the upper edge portion, the lower edge portion or the intermediate portion of the net 7 is attached, the rope 6 is similarly stretched.

The rope tensioning and the net tensioning can be performed by selectively applying the mounting brackets 3 and 4 having various structures as described above and by applying the column mounting bracket 1 having the above-described structure. At the same time, removal and rebuilding are performed easily and accurately and promptly. In addition, changes in the direction in which the rope or net is stretched (front and rear and up and down directions) can be easily dealt with by bending deformation of the left and right helical portions 1b of the pole mounting bracket 1, and excellent construction performance and removal performance. Is obtained. Mounting bracket 1
The rope 6 is buffered and supported by the left and right spiral portions 1b moderately long, and the load of the rope is equalized over the entire length of the rope by the insertion and support of the rope 6 by the two spiral portions 1b, so that the load is concentrated on the rope support portion. In addition to excellent workability, tension and removal performance, reliability, and durability have been significantly improved.

In each of the embodiments described above, the present invention is applied not only to fiber ropes but also to ropes such as cables and wire ropes having a relatively easily bendable structure, and is applied to wire netting in addition to fiber nets.
