Description

  The present invention relates to a fence to which a lattice body formed by arranging a plurality of wires in a lattice shape between support columns.

  As a means for partitioning a boundary with a road, a boundary between sites, and the like, a fence formed by combining a lattice body and a column is used. This grid is generally rectangular when viewed from the front, and is easy to install on a horizontal ground, but when installed on a sloping ground, the grid of the grid can be made into a parallelogram according to the slope. It is necessary to attach the grid body obliquely. However, the former needs to measure the inclination angle of the installation place on site every time, and it is not efficient to create a grid for each inclination angle. In the latter case, when fixing the grid to the column, the position of the wire that intersects the column is not constant, so it is necessary to adjust the fixed position, and there may be places that overlap with the adjacent grid, so landscape There is concern about the decline.

  For example, in Patent Document 1, in a vertically long extending panel having overlapping flanges with adjacent identical panels on both the left and right sides, upper and lower ends on one diagonal line are formed as missing slope edges. A panel has been proposed.

  In addition, as shown in Patent Document 2, the present applicant also attaches a panel between the columns, and attaches support members so as to face the side surfaces of the columns, and the support members form grooves in the vertical direction. A panel fence in which both ends are inserted into the groove of the support member and the panel is attached is proposed.

As a result, the support member 3 is attached to the column 1 via the attachment bracket 4.

  The mounting structure of the support member 3 to the support column 1 is not limited to this embodiment. For example, although not shown, the mounting bracket 4 is arranged before and after the support column 1, and the support member 3 is interposed between the two mounting brackets 4. The form which clamps may be sufficient. The mounting brackets 4 to be fixed to the support column 1 are fixed to the upper, middle, and lower stages of the support column 1, respectively, depending on the height of the fence P, the weight of the lattice body 2 supported by the support member 3, and the like. If the metal fittings 4 can be firmly fixed, the number of the attachment metal fittings 4 fixed to the support column 1 is not limited to this embodiment.

  Next, the support structure of the lattice body 2 with respect to the support member 3 will be specifically described with reference to FIGS. The front wall 31 and the rear wall 32 of the support member 3 are provided with a through hole 36 and a through hole 37 at side positions that do not overlap the mounting hole 34 and the mounting hole 35. The side end portion 24 of the lattice body 2 is inserted between the front wall 31 and the rear wall 32 of the groove 33, and one lattice 2a in the lattice body 2 overlaps with the through hole 36 and the through hole 37 in a front view.

Yes. As a result, the grid 2 a is locked to the fixing bolt B 3, and the side end 24 of the grid 2 is supported so as not to come out from the groove 33 of the support member 3. In this embodiment, the through hole 36 and the through hole 37 provided in the front wall 31 and the rear wall 32 are shifted from the mounting hole 34 and the mounting hole 35 on the side end side away from the support column 1 by shifting the position in the horizontal direction. Thus, when the lattice body 2 is supported in the groove 33, unnecessary interference due to the contact between the lattice body 2 and the fixing bolt B1 penetrating the attachment hole 34 and the attachment hole 35 is less likely to occur. Therefore, it is preferable.

  In the groove portion 33 of the support member 3, in this embodiment, a spacing member 5 that is narrower than the spacing between the front wall 31 and the rear wall 32 is disposed, and between the spacing member 5 and the front wall 31. The grid 2a of the grid 2 is inserted into the grid 2 and the nut N3 is fastened, so that one intersection 23 constituting the grid 2a is sandwiched between the front wall 31 and the front portion of the spacing member 5. Thereby, the lattice body 2 can be firmly fixed in the groove portion 33 of the support member 3. Further, in this embodiment, the spacing member 5 is preferably formed in a ring shape in cross section provided with a through-hole through which the fixing bolt B3 passes, and is not removed from the fixing bolt B3. A notch groove that can be inserted inwardly from the outer peripheral surface of the holding member 5 is provided, and after the fixing bolt B3 is passed through the through hole 36, the lattice 2a, and the through hole 37, the fixing bolt B3 is inserted into the notch groove. It may be inserted and the spacing member 5 may be attached to the fixing bolt B3.

  When the fence P is installed on the flat part and the inclined part, as shown in FIG. 1, when the lattice body 2 is arranged in three stages in the vertical direction, the flat part holds the gap between the upper and lower lattice bodies 3. Even if it can be arranged, in the inclined portion, there is no gap between the lattice bodies 3 adjacent to each other in the vertical direction, and there is a possibility that a part of the upper and lower end portions of the lattice body is superposed in front view. In this case, as in this embodiment, the upper and lower lattice bodies 2 can be obtained by setting the distance between the front wall 31 and the rear wall 32 in the groove portion 33 of the support member 3 to be twice or more the thickness T of the lattice body 2. For example, the spacing member 5 for fixing the upper grid member 2 is disposed on the front wall 31 side, and the spacing member 5 for fixing the lower lattice member 2 is disposed on the rear wall 32 side. Accordingly, as shown in FIG. 7, the upper lattice body 2 is disposed on the front side and the lower lattice body 2 is disposed on the rear side, so that the upper and lower lattice bodies 2 can be attached without being in direct contact with each other. .

  The grid body 2 can increase the strength against the load applied from above the grid body 2 by providing the trunk edge 25 on the top of the grid body 2 arranged at the uppermost stage as in this embodiment. Further, since the grid body 2 other than the uppermost stage is not directly subjected to a load from above, the trunk edge portion 25 is not necessarily required, and unnecessary interference and contact between the grid bodies 2 arranged above and below are avoided. Can do.

  Since the grid body 2 according to the present invention does not require a dedicated panel for an inclined portion even when attached to an inclined land, not only the fence P according to the present invention but also, for example, around a cultivated land in a mountainous area It can be suitably used as a beast harm prevention fence for preventing the invasion of animals installed on the plant, or as a support or growth support for plants planted along a slope, a road, a walkway or the like.
