The present disclosure is not limited to the above-described embodiments, and includes modifications, improvements, and the like within a range that can achieve the purpose of the present disclosure. In the fence mounting structure 1A of the second embodiment shown in FIG. 5, the fence 10A is constructed by arranging the new fence 3 inside the site where the existing fence 2 is installed. The front side of FIG. 5 shows the outside of the site, and the back side shows the inside of the site. As shown in FIGS. 6 and 7 , the existing fence fixing portion 41 is arranged on the surface of the existing fence 2 inside the site. The vertical reinforcement 22 is arranged with respect to the existing fence fixing portion 41 so as to be surrounded by the connecting portion 43 , the fixing portion 411 , the sub-plate 412 and the claw portion 4115 , and is fixed by the screw 413 passing through the fixing hole 414 . Further, the screws 413 are fixed in the through holes 415 a , 415 b , 415 c , 415 d of the fixed position changing portion 415 . At this time, unlike the first embodiment, the screw 413 is fastened so that the shaft head 413b faces the inside of the site and the end of the shaft portion 413a faces the outside of the site. The new fence 3 is brought into contact with the outer surface of the new fence fixing portion 42 and fixed by the binding band 6 .

According to the second embodiment, the new fence 3 can be seen when the outside of the premises is viewed from a building within the premises. In addition, the post 21 of the existing fence 2 is arranged between the existing fence 2 and the new fence 3. - 特許庁When the new fence 3 is installed avoiding the pillars 21, the new fence 3 is spaced inside the existing fence 2. - 特許庁However, since the new fence 3 is located within the site, there is no concern that the structure will protrude outside the site.

As shown in FIG. 4A , the connecting portion 4 has a symmetrical shape between the upper portion and the lower portion of the notch portion 4114 . Therefore, even when the new fence 3 is arranged inside or outside the site of the existing fence 2, the same connecting part 4 can be used by turning it upside down.

In addition, the fixing portion 411 of the connecting portion 4 has a first fixing surface 4111 and a second fixing surface 4112 .

Furthermore, in FIGS. 1 and 5, for convenience of explanation, only one new fence 3 is shown attached, but as shown in FIG. It is conceivable that a plurality of them are connected and arranged. In this case, the connecting portions 4 may be arranged so that the adjacent new fences 3 face opposite sides. Since the connecting portion 43 of the connecting portion 4 is in the shape of a thin plate, even if the connecting portions 43 are brought into contact with each other, it is difficult to form a large gap between the adjacent new fences 3 .

In the above-described embodiment, the fixing position changing portion 415 is configured by two through holes 415a, 415b and 415c, 415d arranged in each of the fixing portion 411 and the sub-plate 412 respectively. However, the fixing position changing portion is not limited to two through holes as long as the position can be changed so as to avoid the vertical stripes and be fixed at a position away from the fixing hole 414 in the left-right direction. Three or more through-holes may be provided. The through-hole may be formed by an elongated hole elongated in the left-right direction, and may be fixed to a screw using a nut at a location where the vertical bar is not arranged.

In the above embodiment, the plurality of screws 413 are fastened through the fixing portion 411 and the sub-plate 412, but this is not the only option. For example, the fixed position changing portion 415 may be configured by a recess having a female thread, and a screw may be screwed into this recess.
