FIG. 4B is a diagram of the fence connection surface 411 viewed from the rear surface 3b side of the new fence 3. As shown in FIG. The existing fence support part 42 is arranged inside the site of the fence connection surface 411 on the back surface 3b side. The ends of the shaft portions of the first fixing portion 431 and the second fixing portion 432 pass through the fence connection surface 411 and the existing fence support portion 42 and are fastened with nuts 46 . FIG. 4C is a side view of the concave member 41, the existing fence support portion 42, the first fixing portion 431 and the second fixing portion 432. FIG.

At least one horizontal reinforcement 23 may be arranged between the first fixing portion 431 and the second fixing portion 432 . For example, as shown in FIG. 3, in this embodiment, the existing fence 2 has portions that curve outward on the upper and lower ends of the site. Two horizontal ribs 23 are arranged between the first fixing portion 431 and the second fixing portion 432 on the upper end side of the existing fence 2 . Two horizontal ribs 23 are sandwiched between the first fixing portion 431 and the second fixing portion 432 . On the other hand, on the lower end side of the existing fence 2 , one horizontal reinforcement 23 is arranged between the first fixing portion 431 and the second fixing portion 432 . As long as the horizontal ribs 23 are placed between the upper and lower portions of the pair of fixing portions 43, the pair of fixing portions 43 and the horizontal bars 23 need not be held in contact with each other. By locking the first fixing portion 431 on the horizontal reinforcement 23 , the recessed member 41 and the existing fence support portion 42 are fixed with the existing fence 2 sandwiched therebetween. Since the first fixing portion 431 and the second fixing portion 432 are fixed at two points above and below, the connection is strong.

According to the first embodiment, the following effects are achieved. A fence mounting structure 1 is configured such that a new fence 3 is mounted on an existing fence 2 formed by assembling vertical reinforcements 22 and horizontal reinforcements 23 in a grid pattern. The fence mounting structure 1 is composed of a pair of fence connecting surfaces 411 facing each other with a predetermined interval, a connecting portion 412 connecting the pair of fence connecting surfaces 411, and one fence connecting surface of the pair of fence connecting surfaces 411. 411 and an existing fence supporting part 42 for sandwiching and supporting the existing fence 2, and the horizontal reinforcement 23 are arranged so as to sandwich from above and below, and are fixed to the pair of fence connection surfaces 411 through the existing fence supporting part 42. and a pair of fixing portions 43 . A pair of fixing portions 43 and a fence connection surface 411 are fixed to the existing fence 2 via the existing fence support portion 42 . Therefore, by fixing the fence connection surface 411 to the new fence 3, the existing fence 2 and the new fence 3 can be connected and the fence 10 can be installed without removing or partially replacing the existing fence. Therefore, the new fence 3 can be easily added without requiring large-scale construction or large costs. By adding a new fence 3 to the existing fence 2, it is possible to blindfold the site with a plate-shaped panel so that the inside of the site is difficult to see, or to enclose the site with a new fence 3 with a desired design. Increased convenience.

According to this embodiment, the new fence 3 is arranged outside the site where the existing fence 2 is installed, and arranged between the pair of fence connecting surfaces 411 . By arranging the new fence 3 outside the existing fence 2, the appearance when viewed from the outside is improved. At this time, since the new fence 3 is arranged between the pair of fence connecting surfaces 411, the gap between the existing fence 2 and the new fence 3 can be reduced. Since it is often the outside of the existing fence 2, the road surface, or another person's site, the area of the structure protruding outside the site can be reduced by reducing the gap between the existing fence 2 and the new fence 3. - 特許庁

According to this embodiment, the lower end of the new fence 3 is supported by the installation surface 24 on which the existing fence 2 is installed. Since the load of the new fence 3 itself is supported by the installation surface 24 only by connecting the new fence 3 to the existing fence 2 in the thickness direction of the fence 10, the structural strength of the fence mounting structure 1 can be obtained sufficiently. can be done. Therefore, it becomes possible to secure safety and durability while facilitating the work of attaching the new fence 3 to the existing fence.

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 configured by arranging the new fence 3 inside the site where the existing fence 2 is installed. As shown in FIG. 6, the concave member 41 is connected with one of the pair of fence connection surfaces 411 contacting and connected to the existing fence 2 and the other contacting and connecting the vertical frame 311 of the new fence 3 . be. In this state, the shaft heads of the first fixing part 431 and the second fixing part 432 are arranged inside the premises, and the shaft parts extend from the inside of the premises to the outside of the premises. The first fixing part 431 and the second fixing part 432 pass through the existing fence 2 , the new fence 3 , the pair of fence connection surfaces 411 and the existing fence support part 42 , and connect and fix the new fence 3 to the existing fence 2 .

As shown in FIGS. 6 and 7, when the new fence 3 is arranged inside the existing fence 2, since the posts 21 of the existing fence 2 protrude, the grid of the vertical and horizontal bars 22 and 23 of the existing fence 2 is not formed. There is a part where the newly installed fence 3 cannot be attached directly. Here, the dimension T1 in the thickness direction connecting the outer side surfaces of the pair of fence connection surfaces 411 is configured to be larger than the dimension T2 in the thickness direction of the post 21 . It should be noted that the phantom lines around the struts 21 shown in FIG. 6 are the lines of the end caps located on top of the struts. With this configuration, one side of the fence connection surface 411 is fixed inside the existing fence 2 and the other side of the fence connection surface 411 is fixed to the new fence 3 via the connecting portion 412, whereby the new fence 3 are separated from the existing fence 2 by a dimension T1 in the thickness direction connecting the outer surfaces of the pair of fence connection surfaces 411 . A dimension T2 in the thickness direction of the post 21 is smaller than a dimension T1 connecting the outer surfaces of the pair of fence connection surfaces 411 . Therefore, the new fence 3 can be arranged inside the existing fence without intervening extra parts other than the connecting part 4.例文帳に追加

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. Also, even if the new fence 3 is installed avoiding the posts 21 of the existing fence 2, there is no concern that the structure will protrude outside the site because the new fence 3 is located within the site.

In the above-described embodiment, the configuration in which the pair of fixing portions 43 are fixed to both of the pair of fence connecting surfaces 411 has been described. However, the pair of fixing portions 43 may pass through the existing fence support portion 42 and be fixed to at least one side of the fence connection surface 411 . Fixing to the other fence connection surface may be performed by other means such as engagement or fitting, or another bolt or the like may be used.
