E. Furthermore, the both ends of the upper side and the lower side of the perforated panel 4 and the supporting rope 3 are connected by a suspension structure that maintains a parallel state.

Hereinafter, the present invention will be described based on illustrated embodiments.
The fence 1A shown in FIG. 1 to FIG. 3 includes two support ropes 3 installed in the horizontal direction above and below the columns 2 and 2 that are set up at intervals, along the support ropes 3. In the case of the illustrated example, two perforated panels 4 and 4 having a rectangular shape that is long in the left-right direction are suspended by being connected to the supporting rope 3 in parallel with the upper sides 4c and 4c and the lower sides 4d and 4d. The two perforated panels 4, 4 are arranged in an arrangement E in which the vertical sides 4 b, 4 b of the end portions adjacent to each other wrap around the entire length. The upper ends of the columns 2 and 2 are firmly connected by joining the beam member 6 to the mounting member 2 b of the column 2. As the support rope 3, for example, a wire or rope is used, and a catenary curve is drawn by its own weight and the weight of the perforated panel 4. For example, concrete pillars, steel pipe pillars, H-shaped steel pillars, truss pillars, or the like are adopted as the pillars 2, and ribs 2 a for attaching the ends of the support ropes 3 are provided. Although illustration is omitted, the vertical sides 4b and 4b of the two perforated panels 4 and 4 and adjacent end portions are arranged so that only the upper portion wraps. Also good.

As the perforated panel 4, for example, a hot dip galvanized steel sheet having a vertical and horizontal dimension of about 1 m × 6 m and a thickness of about 1.5 mm is used. The hole 4a of the perforated panel 4 is formed on the entire surface of the panel 4 with an oblong hole 4a that is long in the vertical direction orthogonal to the direction supported by the support rope 3 (for example, the vertical width is about 50 mm and the horizontal width is about 14 mm). And a large number are provided in a regular arrangement in the vertical and horizontal directions, for example, with an aperture ratio of about 40%. The effective cross-sectional portion excluding the cross-sectional defect portion due to the oval hole 4a has longitudinal and lateral strength bones that are linearly continuous with a constant width dimension (for example, W ₁ ≈4 mm, W ₂ ≈15 mm). 4e and 4f. That is, the longitudinal force bone 4e orthogonal to the direction supported by the support rope 3 forms the lateral opening width of the oblong hole 2 as small as possible, and thus the oblong holes 4a, 4a adjacent in the lateral direction. The matrix space between them (interval W ₂ between the hole edges) is as wide as possible to ensure an effective cross-sectional area that can withstand the tensile stress and compressive stress of the support rope 3. On the contrary, in the lateral force bone 4f parallel to the direction supported by the support rope 3, the row interval (interval W ₁ between the hole edges) of the oblong holes 4a, 4a adjacent in the vertical direction is unlimited. It has a narrow width and an effective cross-sectional area that allows the shape of the fence to be maintained. The oblong holes 4a of the perforated panel 4 do not necessarily have to be provided on the entire surface of the panel, and may be implemented in a concentrated manner only in a part of the panel.

  The reason why the oblong hole 4a which is long in the vertical direction perpendicular to the direction in which the perforated panel 4 is supported by the supporting rope 3 is adopted as the hole 4a of the perforated panel 4 is that of the previous Japanese Patent Application 2005-2005. As described in detail in 189333 (Japanese Patent Publication No. 2007-9465), when the perforated panel 4 receives wind pressure and receives a large tensile load or compression load between the upper and lower support ropes 3, 3. In order to ensure the cross-sectional area to withstand the tensile stress or the compressive stress by designing the lateral hole edge spacing as large as possible while achieving the high opening ratio of 40% as described above, Because it is advantageous. This is because a relatively thin metal plate can be used as much as the gap between the hole edges in the lateral direction is large, and as a result, drilling is facilitated and a lightweight fence panel can be provided. Therefore, when the above consideration is not particularly emphasized, a round hole or an elliptical hole can be adopted as the hole, or a structure in which the holes having various shapes are mixed can be implemented.

  As the configuration in which the upper side 4c and the lower side 4d of the perforated panel 4 are connected to and suspended from the supporting rope 3 in a parallel state, the upper side 4c, 4c or the lower side 4d, 4d of each perforated panel 4, the upper side 4c and the lower side A spiral wire 5 as a panel suspension is passed through a series of states through through holes 5a provided at a small pitch along 4d, and is connected to the support rope 3 so as to be sewn and suspended in a parallel state. Specifically, the tip of the spiral wire 5 is passed through a through hole 5a (starting end) provided at one end of the upper side 4c and the lower side 4d of the perforated panel 4, and the wire 5 is passed through the support rope 3. The wire 5 is rotated through the adjacent through-hole 5a to the through-hole 5a (terminal portion) provided at the other end of the upper side 4c and the lower side 4d. The both ends of the are fixed by means such as caulking. That is, the upper side 4c and the lower side 4d of the perforated panel 4 and the supporting rope 3 can be connected in a parallel state very easily and reliably without the need for special techniques or dedicated mounting hardware. However, the spiral wire 5 may be configured to intermittently pass through the through holes 5a on the upper side and the lower side of each perforated panel 4.

Although illustration is omitted, the panel hanger can be implemented by using, for example, a ring-shaped connecting member, a carabiner, a hook with a stopper, or a shackle in addition to the spiral wire 5. In this case, it is desirable to attach a reinforcing material such as a round pipe to a position where the shackle or the like of the support rope 3 is hooked to prevent the support rope 3 from being damaged by a concentrated load such as a shackle.
Further, the through hole 5a is not necessarily provided, and the spiral wire 5 is passed through the hole 4a, which the perforated panel 4 originally has along the upper and lower edges, through a series of states so that the support rope 3 is sewn. It can also be connected in parallel.

  As shown in enlarged views in FIGS. 2 and 3, the four corners of the perforated panel 4 are reinforced to have a strength that can withstand a suspension load, and the rigid members 9 and 10 attached to the reinforced portion are tightly coupled to the support rope 3. Then, the both ends of the upper side and the lower side of the perforated panel 4 and the supporting rope 3 are connected by a suspension structure that maintains a parallel state. This is to increase the strength and durability of both ends of the upper and lower sides of the perforated panel 4 that are particularly prone to breakage due to concentrated stress due to wind loads or repeated loads due to impacts of articles. Below, the suspension structure which maintains the four corners of the perforated panel 4 in a parallel state will be described with reference to FIGS.

First, FIG. 2 shows a suspension structure that keeps the upper edge of the perforated panel 4 on the column 2 side and the supporting rope 3 in a parallel state. Both ends of the support rope 3 are processed into a ring shape, the thimble 3a and the rib 2a of the support column 2 are connected to each other by a connecting member 8 such as a reinforcing shackle, and the support rope 3 is installed on the support column 2. Yes. The upper edge part of the perforated panel 4 is formed in a chamfered shape cut at an angle that does not cause interference with the thimble 3a of the support rope 3, and the chamfered shape part F is formed by removing the reinforcing material 7 made of zinc iron plate. It is attached and reinforced by a bet joint or the like. The through hole 5a provided in common to the perforated panel 4 and the reinforcing member 7 is connected and fixed through the terminal portion of the spiral wire 5. A connecting hole is provided adjacent to the outside of the fixing position, and a rigid member 9 such as a reinforced shackle is attached to the connecting hole with a stop pin 9a, and the other side of the rigid member 9 is the support rope. 3 thimbles 3a.
The suspension structure that keeps the lower end of the perforated panel 4 on the support 2 side and the support rope 3 in a parallel state is the upper end of the perforated panel 4 on the support 2 side and the support rope 3 shown in FIG. Is the same configuration as the suspension structure that keeps the two in parallel.

  Next, FIG. 3 shows a suspension structure in which the portion E where the two perforated panels 4, 4 lie side by side and the adjacent end portions on the center side wrap and the supporting rope 3 are kept in parallel. The wrap portion E of the perforated panel 4 or the vicinity of the wrap portion E is reinforced by attaching the reinforcing member 11 by rivet bonding or the like, and spirals to the through hole 5a provided in common to the perforated panel 4 and the reinforcing member 11 Connection and fastening are performed through the end of the wire 5. A connecting hole is provided adjacent to the inside of the fixing position, and a rigid member 10 such as a reinforced shackle is attached to the connecting hole with a stop pin 10a, and the other side of the rigid member 10 is connected to the supporting rope 3. Tightening has been done.

As shown in FIG. 3 and FIG. 4, the horizontal side and the vertical side portion where the two perforated panels 4, 4 wrap each other are made of ultrahigh molecular weight polyethylene that prevents the panels 2, 2 from rubbing against each other. In the illustrated example, the rubbing prevention sheet 16 is attached to four contact groups as vertical or horizontal groups so as to be effective in preventing rubbing on both contact surfaces of the perforated panel 4.
The rubbing prevention sheet 16 has a width of about 71 mm, a length of about 7 mm, and a thickness of about 1 mm. As shown in FIG. 5, the adhesive sheet 16 is bonded to the perforated panel 4 with a rivet 17a. The polyethylene tape 18 and the stainless steel spacing member 17 are sandwiched between them, and the central part is joined to the perforated panel 4 with rivets 16a in a slightly raised state. The spacing member 17 is configured such that both ends are bent to one side and a recess is provided in the central portion, and the head portion of the rivet 17a is accommodated in the recess and does not contact the rubbing prevention sheet 16. The inner polyethylene tape 18 prevents the perforated panel 4 made of a steel plate from corroding due to contact with the stainless steel spacing material.

Since the fence 1A according to the present embodiment has the above-described configuration, stress concentration at the end of the perforated panel 4 can be prevented even if the load due to wind load or collision of articles is repeatedly received. The strength and durability of the end portion can be increased, and a long service life can be demonstrated over a long period of time, which can be used soundly.
Further, as shown in FIG. 6, the two perforated panels 4 and 4 are configured to be vertically displaceable together with the supporting rope 3, and when subjected to a load due to wind load or an impact of an article, the acting force is exerted. Since the position of the perforated panels 4 and 4 can be freely changed so as to avoid or escape, the load can be reduced, so that it can greatly contribute to the improvement of durability and the maintenance of soundness.

In the fence 1A of this embodiment, as shown in FIG. 7, support ropes are respectively installed between the plurality of pillars 2 standing at a predetermined interval, and along the support ropes. The two perforated panels 4 and 4 having a quadrangular shape are suspended with their upper and lower sides connected in parallel with the supporting rope, and the two perforated panels 4 are arranged side by side. It can also be implemented in an arrangement where the vertical sides of the parts wrap.

Two supporting ropes 3 are installed in the vertical direction between the support columns 2, 2, and the supporting rope 3 arranged between the upper and lower perforated panels 4, 4 is the upper perforated panel 4. It is commonly used for perforated panels in the lower tier. The spiral wire 5 connecting the lower perforated panel 4 and the supporting rope 3 is intermittently passed through a hole provided along the upper side of the lower perforated panel 4. Reinforcing members 7 and 11 provided at the four corners of the upper and lower perforated panels 4 have a smaller shape than the reinforcing members 7 and 11 of the fences 1A and 1B shown in FIGS.
