The vertical line 3 and the horizontal line 4 are welded at their intersections to form a rough grid pattern, which is disposed adjacent to the grid door A on each suspension base side of the grid door A. Thus, the fence C is formed by arranging the grid door A in series so as to partition the boundary of the site in the longitudinal direction.

  In the grid door A, the vertical lines 3 and the horizontal lines 4 having a predetermined arrangement pitch are welded at their intersections to form a rough grid pattern, and the arrangement pitch of the vertical lines 3 is reduced in the vicinity of one end in the width direction. A vertical line 5 for pitch reduction is arranged in the vicinity of the end portion, and welded to the cross rail at the intersection thereof to form a grid panel with a vertical line coarse and dense arrangement in which the vicinity of the end portion is partially formed in a dense grid pattern. The grid panel is provided with a door frame, and one end of the above-mentioned dense lattice lattice is used as a door side for locking, and the other end of the coarse lattice lattice is attached to the support column 12 as a suspension side. In this case, the ends of the pair of grid doors A in the form of a dense grid are arranged symmetrically in the width direction so that both door side designs are made common.

  In this example, the grid panel of the grid door A has, for example, a trunk edge 6 with a height of about 1.7 m and a width of about 0.7 m, and a curved section formed in a C-shaped section or a circular section in the vertical direction. The grid panel has a large number of vertical lines 3 and horizontal lines 4 in the vertical line 3 at a pitch of 5 cm in the width direction, and in the horizontal line 4 at a pitch of 13.5 cm in the vertical direction. Arranged in parallel and welded at the intersections of the vertical lines 3 and horizontal lines 4 to form a grid of rectangular grids corresponding to the pitch, and at one end in the width direction thereof In this example, the pitch is reduced to about a fraction of the area ratio, in this example about 1/5, the same as the vertical line for pitch reduction, that is, the large diameter as in the vertical line 3 and horizontal line 4, in this example A pitch reducing vertical line 5 having the same diameter as the vertical line 3 and the horizontal line 4 is arranged, Similarly, by performing welding at the intersections, the area portion is formed into the above-mentioned dense mesh lattice shape, and the coarse mesh lattice portion 1 and the dense lattice lattice portion 2 with the above pitch are arranged in a vertical line coarse and dense manner.

In this way, it is made of an aluminum frame formed so as to form a Japanese letter shape by the vicinity of the upper and lower ends and the intermediate horizontal beam 8. The metal fixture is fixed by hooking the hook 9 protruding from the horizontal beam 8 to the horizontal line at the position of the horizontal beam 8 on the grid panel and pulling it toward the horizontal beam 8 side. The drawing to the side rail 8 side is performed by fastening a nut (not shown) screwed to the side rail penetration shaft of the hook 9 on the back side of the side rail 8.

  The grid door A is suspended and supported on the support column 12 with the dense mesh lattice portion 2 as the door end side and the coarse mesh lattice portion 1 as the suspending side. It is assumed that a dense grid lattice portion 2 is arranged.

  The support column 12 is made of a hollow aluminum extruded material. In this example, the support column 12 is used for a partition type fence used for supporting the grid fence, and the grid door to the support column 12 is used. The suspension support of A is made openable and closable by a hinge bracket 13 fixed to the support column 12 and the grid door A, while the support of the grid fence B1 to the support column 12 is supported by the protrusion of the end band 14 wound and fixed thereto. A vertical line at the end in the width direction is sandwiched between the pieces by fastening bolts and nuts. At this time, the grid fence B1 is adjacent to the grid fence and has a grid fence of the same configuration in the fence surface direction (not shown). ) Are sequentially supported on the pillars of a predetermined interval using a connecting straight line or a band for a corner, and the series installation is performed.

  In the figure, 11 is a lever handle for opening and closing the grid door A.

  The fence C of the present example using the double doors formed in this way can be used, for example, even when a cylinder lock or a thumb lock with a thumb turn is installed and used as the locking device 10. In the vicinity, there is the above-mentioned dense mesh lattice part 2, and the vertical line pitch of the mesh is 2.5 cm, and the part 2 has an area of about 30 cm in the width direction and about 80 cm in the vertical direction. Depending on the pitch, even if there is a possibility that the vertical line 3 may be somewhat bent, even if the length from the hand of the person to the arm and the bending of the wrist are taken into consideration, even if the hand is inserted and inserted from the part 2 outside the site The thumb turn cannot be rotated and the lock cannot be removed, so that the unlocking of the locking device 10 and the invasion of the person by this can be surely prevented. In addition, the grid door A of the double doors has a dense mesh latticed end arranged symmetrically in the width direction, and the door side design of both sides is made common so that the dense mesh lattice portion 2 is left and right. As a result of the visual recognition of the dense mesh lattice portion 2 from a distance, the position of the entrance / exit of the fence C can be easily identified, while the double mesh door has a dense mesh lattice design. Can have a good appearance in harmony with the design of the double doors and the fence C as a whole by arranging them partially on the double doors based on the grid lattice design of the grid fence B1. Moreover, in order to prevent unlocking from outside the site, the pitch reduction vertical line 5 may be additionally arranged, and this additional arrangement can be achieved at a cost increase of about an additional material cost in the grid panel manufacturing process. From can be carried out as much as possible suppress an increase in its cost.

  FIG. 4 to FIG. 6 show other examples. In this example, the fence C is formed in the same manner as described above, and the vertical line coarse / dense densely formed in the vicinity of the end part and having a partially dense grid pattern. Using a pair of arranged grid panels, a door frame is applied to one of the grid panels, and one end of the dense grid pattern is the door end side for locking, and the other is a coarse grid pattern. One end of the grid door A is suspended from and supported by the support column 12 with the end portion as a suspension side, and the other grid panel is supported by the support column 12 to form a grid fence B2. The grid fence B2 is connected to the dense mesh. One end portion in the form of a lattice is used as a door end side for locking the grid door A, and is arranged adjacent to the grid door A. At this time, the dense grid pattern of the pair of grid panels is used. Both doors are arranged symmetrically in the width direction. It is common the side design.

  That is, the grid door A has the same configuration as that shown in FIGS. 1 to 3 and is suspended and supported on the support column 12 to form a single door, and the locking device between the vertical rod 7 on the door side and the support column 12 is used. And the grid fence B2 on the column 12 on the side where the locking device 10 is installed, and the end portion so that the dense lattice portion 2 is adjacent to the grid door A side, that is, the door end side of the grid door A. While fixing with the band 14, the grid fence B1 made into the rough grid | lattice grid | lattice form like the said example other than the grid fence B2 arrange | positioned at the support | pillar 12 of the grid door A at the suspension origin side and the said door-end side is used as a fence. By arranging sequentially in the C width direction, the grid door A is arranged in series so as to partition the boundary of the site in the longitudinal direction.

  Since the remainder is not different from the example of FIGS. 1 to 3 described above, a duplicate description is omitted.

  Even in this example, the one-sided grid door A and the grid fence B2 on the door end side are inserted by inserting a hand from the dense grid lattice portion 2 to unlock the locking device from outside the site. The grid door A and the door-side grid fence B2 are arranged symmetrically in the width direction so that both ends of the grid door A and the door-side grid fence B2 are symmetrically arranged in the width direction. By sharing the design of the door-end side, the dense grid part 2 is continuously arranged on the left and right, so that the dense grid part 2 can be seen from the same distance, and the entrance of the fence C Further, the dense grid pattern design is based on the grid pattern design of the hanging fence side and the other grid fence B1 and the one-sided grid door A and its doors.
