The one attachment member 51 and the second attachment member 53 can be relatively slid by the slide means.

  The fixture 4 thus assembled is attached to the column member 3 from the side at the vertical height position where the insertion hole 21 is formed. In this case, from the gap between the first locking piece 65 of the holding portion 55 of the first mounting member 51 and the second locking piece 71 of the pressing portion 56 of the second mounting member 53, the vertical wire 5 a at the end is the holding portion. 55 and the pressing portion 56, the support member 4 is rotated in a horizontal plane so that the side surfaces 80a and 81a are brought into contact with the projecting surface 15, and the attachment member 4 is pulled backward to support the column member 3. The rear surface 50 a of the first bottom wall portion 50 is brought into contact with the mounting surface 13. If it does in this way, the 1st bottom wall part 50 will be in the state pinched | interposed between the protrusion surface 15 of the support | pillar member 3, and the opposing surface 24 of the protrusion 23 (refer FIG. 10 thru | or FIG. 13).

  Subsequently, the tightening screw 20 is inserted into the insertion hole 21, further inserted into the insertion hole 84 of the first bottom wall portion 50, and screwed into the screw hole 85 of the second bottom wall portion 52. When the tightening screw 20 is rotated in this manner, the tightening screw 20 is screwed into the female screw of the screw hole 85, and the head of the tightening screw 20 comes into contact with the back surface 22 of the mounting wall portion 14. Since it does not move forward, the middle bent portion 62 and the second connecting portion 70 slide so that the second bottom wall portion 52 moves backward between the first bottom wall portion 51 and the middle bent portion 62. The second connecting portion 70 is guided by the inner surfaces of the guide claws 75 and 76, and the second bottom wall portion 52, that is, the second mounting member 52 is pulled backward.

  Further, by rotating the tightening screw 20, the pressing portion 56 is drawn toward the holding portion 55 (see FIG. 11), and the vertical wire 5 a at the end is moved by the holding surface 66 of the holding portion 55 and the pressing surface 72 of the pressing portion 56. It is pinched and held. At this time, since the first retaining piece 65 and the second retaining piece 71 are displaced from each other in the left-right direction, they do not interfere when the vertical wire 5a is sandwiched (see FIG. 12). Further, when the vertical wire 5a at the end is sandwiched and held between the holding surface 66 of the holding portion 55 and the pressing surface 72 of the pressing portion 56, the second bottom wall portion 52 comes into contact with the first bottom wall portion 51. It is preferable to configure so as to be (pressure contact).

When the tightening screw 20 is rotated, the fixture 4 also receives a force in the rotational direction. In the fixture 4, the first bottom wall portion 50 is located between the protruding surface 15 and the facing surface 24. Since it is in the sandwiched state, the protruding surface 15 and the facing surface 24 (the protruding wall portion 16 and the protruding portion 23) function as rotation suppressing means.
The mounting operation of the mounting tool 4 as described above is performed at the site where the insertion hole 21 is formed for the first support member 3A and the second support member 3B, and the vertical wire 5a at the end is attached to the mounting tool 4 by the mounting tool 4. The fence 1 can be constructed by being held and held by the holding portion 45 of 4.

In the fence 1 having the above-described configuration, the reticulated fence body 2, particularly the vertical wire 5, is not directly held (contacted) by the support member 3, and is disposed on the support member 3 at intervals in the vertical height direction. Since the net-like fence body 2 is held via the fixture 4, the fixture 4 is a member that contacts the column member 3. Therefore, a region where dirt such as rust is generated can be narrowed as compared to a case where a member that is long in the vertical direction, such as a vertical wire, is in contact with the support member. For this reason, the frequency of maintenance can be suppressed and the operation is also facilitated.
Further, the mounting wall portion 14 and the protruding wall portion 16 are formed such that the thickness t1 of the protruding wall portion 16 is smaller than the thickness t2 of the mounting wall portion 14, and the mounting wall portion 14 has a hollow portion 17. Therefore, the column member 3 can be reduced in weight by that amount and is easy to handle.

Furthermore, since it is possible to assemble the fixture 4 to the support member 3 in a state where the placing wire portion 7 of the mesh fence 2 is temporarily placed on the covering member 12, the workability is excellent accordingly.
Furthermore, since the column member 3 has a mounting wall portion 14 with a wide left and right width at the rear portion and a protruding wall portion 16 with a narrow left and right width at the front portion, the presence of the column member 3 is faint and beautiful. Becomes an excellent fence 1. Further, by providing the mounting wire portion 7 formed in a rectangular frame shape and providing the lower rear bent portion 9, the net-like fence body 2 is given a sense of volume and stability as a whole. In this respect, it is excellent in aesthetics.
