These are explanatory drawings which show the opened / closed state of the connection member 4 of FIG. The connecting member 4 includes a front plate 5 and a back plate 6, and the upper end of the front plate 5 and the upper end of the back plate 6 are connected via a connection portion 41. The front-rear relationship between the front plate 5 and the back plate 6 is temporarily named with the front plate 5 as the front plate 5 and the back plate 6 as the back plate 6 in the state where the lattice body 2 is connected. The back plate 6 may be positioned in front and the front plate 5 may be positioned in the rear, and the front-rear relationship is not particularly limited.

  The connecting member 4 is generally manufactured by pressing a single plate material made of a stainless alloy, but may be manufactured from another metal plate material such as an aluminum alloy or a steel material. Further, in this embodiment, the connecting portion 41 is constituted by two strip-like connecting pieces 41a on the left and right sides with the center portion notched. This makes it easy to bend the connecting portion 41 and facilitates opening and closing between the front plate 5 and the back plate 6 as shown in FIG. 5, but it is not necessary to provide the cutout or the cutout portion. May be arranged side by side in the left-right direction, and three or more connecting pieces 41a may be provided.

  6 to 9 show the vicinity of the connecting member 4 in FIG. 1, FIG. 6 is an explanatory diagram thereof, FIG. 7A is an enlarged front view, FIG. 7B is an enlarged rear view, and FIG. (B) is an enlarged bottom view, and FIG. 9 is a side view of FIG. That is, the vertical wires 21 at the side ends of the lattice bodies 2 adjacent in the left-right direction are connected to each other via the connecting member 4, and the back plate 6 extends from the bolt insertion hole 51 provided in the center of the front plate 5 of the connecting member 4. A fastening bolt B is screwed toward a female screw hole 61 provided at the center of the front plate 5 and is fastened so that the front plate 5 and the back plate 6 are not closed and spread. The bolt insertion hole 51 of the front plate 5 has a larger diameter than the outer diameter of the screw of the fastening bolt B so that the fastening bolt B can be screwed into the female screw hole 61 without being misaligned. In this embodiment, the female screw hole 61 is formed by processing the back plate 6. The bolt insertion hole 51 may be provided in the back plate 6 and the female screw hole 61 may be provided in the front plate 5. The positions of the bolt insertion holes 51 and the female screw holes 61 are not particularly limited, and may be provided at positions that do not interfere with the vertical wires 21 and the horizontal wires 22 of the lattice body 2. Furthermore, in this embodiment, ribs 51 a and ribs 61 a are provided around the bolt insertion hole 51 and the female screw hole 61 to increase the rigidity of the front plate 5 and the back plate 6.

And in order to connect the side edges of the adjacent grid bodies 2, the vertical wires of the grid bodies 2 to be connected with the front plate 5 and the back plate 6 of the connecting member 4 being opened in a square shape. 21 is arranged on each of the left and right sides of the connecting portion 41, and then the connecting portion 41 is bent to close the space between the front plate 5 and the back plate 6, that is, the front plate 5 and the back plate 6 are substantially parallel to each other. Alternatively, the vertical wire 21 may be positioned between the front plate 5 and the back plate 6 by further folding it into a side view.
The front plate 5 is provided with a front side wall 52 bent at both ends at the rear side, the back plate 6 is provided with a rear side wall 62 bent at both sides at the front side, and both sides of the front plate 5. A part of the front end of the front side wall 52 is disposed so as to cover the outer side of the rear side wall 62 on both side ends of the opposing back plate 6, whereby a part of the front side wall 52 is formed on the rear side wall 62 in a side view. Polymerized. Thereby, the vertical wire 21 positioned between the closed front plate 5 and back plate 6 is prevented from moving in the left-right direction and the front-rear direction with respect to the connecting member 4.

  In addition, a notch 53 having a rectangular shape in a side view is provided at the lower part of both front side walls 52 from the front end to the base end, and the notches 53 of the front side wall 52 are opposed to the both rear side walls 62. A notch 63 having a rectangular shape when viewed from the side is provided at the lower portion thereof from the front end, and passes through an opening having a horizontally long rectangular shape when viewed from the side formed by the notch 63 and the notch 53 from the inside of the connecting member 4. Thus, a passage portion 42 communicating with the outside of the connecting member 4 is formed. Above and below the passage part 42, there is provided a superposition part 43 in which a part of the front side wall 52 is superposed on the rear side wall 62 in a side view. That is, when the vertical wire 21 at the side end of the grid 2 to be connected is positioned between the front plate 5 and the back plate 6, the vertical wire is closed when the front plate 5 and the back plate 6 are closed. 21 and the lower horizontal wire 22 which comprises the crossing part 23 are each arrange | positioned at the passage part 42. As shown in FIG. Thereby, the horizontal wire 22 is prevented from moving in the front-rear direction by the overlapping portion 43, and can support the intersecting portion 23 of the lattice body 2 so as not to come out of the inside of the connecting member 4.

  The shape of the cutout portion 53 and the cutout portion 63 that form the horizontal opening in which the horizontal wire 22 is disposed is not limited to the rectangular shape as in the present embodiment, but the bottom portion of the cutout portion 53 and the cutout portion 63 is If the back surface of the front plate 5 and the back plate 6 is reached, that is, if the notch 53 and the notch 63 are formed up to the base ends of the front side wall 52 and the rear side wall 62, the front plate 5 and the back plate 6 are formed. Even when the gap between the two is closed, the horizontal wire 22 and the cutout portion 53 and the cutout portion 63 do not interfere with each other in the front-rear direction.

  Furthermore, a front bottom wall 54 is provided at the lower end portion of the front plate 5 and extends rearward while leaving a left and right gap S1 through which the connecting vertical wire 21 can pass vertically. As a result, the rigidity of the front plate 5 can be increased, and the left and right horizontal wires 22 are locked to the front bottom wall 54 to the outside of the connecting member 4 even if a load or the like pulling downward with respect to the lattice body 2 occurs. Is difficult to escape. Assuming that the vertical wire 21 is arranged rearward, in this embodiment, the lower end portion of the back plate 6 leaves a gap S2 through which the vertical wire 21 of the grid 2 can pass on the left and right and faces forward. A rear bottom wall 64 is provided. In this embodiment, the lower edges of both notches 53 of the front side wall 52 and the upper surface of the front bottom wall 54 are matched, and the lower edges of both notches 63 of the rear side wall 62 and the height of the upper surface of the rear bottom wall 64 are combined. Therefore, when a load is generated downward on the horizontal wire 22, the horizontal wire 22 is supported in cooperation by the notch 53 and the front bottom wall 54, and the notch 63 and the rear bottom wall 64. Is more preferable.

  Here, one form of the concrete connection means which connects the grid bodies 2 using the connection member 4 is demonstrated with FIGS. First, as shown in FIG. 10, as the state where the front plate 5 and the back plate 6 of the connecting member 4 are opened in a square shape, the lattice bodies 2 connected to the left and right of the connecting member 4 are respectively arranged, The vertical wire 21 at the side end of the lattice body 2 is disposed between the front side wall 52 and the rear side wall 62 of the connecting member 4 on both the left and right sides of the connecting portion 41 of the connecting member 4, and the front plate 5 and the back plate 6 Position between.

  The upper corners of the front side wall 52 and the rear side wall 62 are notched obliquely, and a front inclined part 55 and a rear inclined part 65 are provided. Accordingly, when the vertical wire 21 is passed between the front side wall 52 and the rear side wall 62, the front inclined portion 55 and the rear inclined portion can be obtained without opening the opening angle between the front plate 5 and the back plate 6 so much. The vertical wire 21 can be passed through the gap S3 with 65. The cut-out angles of the front inclined portion 55 and the rear inclined portion 65 are not particularly limited, but the front plate 5 and the back plate 6 until the edges of the front inclined portion 55 and the rear inclined portion 65 are substantially parallel. When the gap is opened, the separation distance of the gap S3 may be longer than the outer diameter R of the vertical wire 21 so that the vertical wire 21 can be passed through the gap S3. That is, when the connecting member 4 is manufactured, the opening angle between the front plate 5 and the back plate 6 may be set to be an easy manufacturing angle. When the connecting member 4 is used, the opening angle is set to the front inclined portion 55 and the rear inclined portion 65. Therefore, it is not necessary to increase the crossing angle more than necessary at the time of construction, and the workability can be improved.

  FIG. 12 is a plan view of FIG. In a state where the vertical wire 21 at the side end of the grid 2 to be connected is positioned between the front plate 5 and the back plate 6, the horizontal wire 22 below which constitutes the intersection 23 with the vertical wire 21 is The end 22 a is located closer to the center of the connecting member 4 than the side end of the connecting portion 41. As a result, as shown in FIG. 11, if the vertical wires 21 of the two grid bodies 2 to be connected are positioned between the front plate 5 and the back plate 6 of the connecting member 4, the connecting member 4 falls from that position. Even if, the horizontal wire 22 is caught by the connection part 41, and does not fall under it, the connection member 4 can be temporarily fixed. Further, in this embodiment, the vertical wire 21 of the grid 2 is disposed on the front plate 5 side in front of the horizontal wire 22, and in addition, the front plate 5 has a shape relationship with respect to the back plate 6, that is, the front plate 5. Since the front wall 52 is slightly heavier because it is higher than the rear wall plate 62 and the rear wall plate 62 is superposed, the front wire 52 is not shown when the horizontal wire 22 is caught by the connecting portion 41. The plate 5 stands up so as to face vertically. Thereby, the vertical wire 21 arranged between the front plate 5 and the back plate 6 is prevented from moving outward by the front side wall 52 of the front plate 5, so that the connecting member 4 can be temporarily fixed more securely. can do. Therefore, since the connecting member 4 can be removed in the initial state in which the crossing angle between the front plate 5 and the back plate 6 is not changed even after temporary fixing, it is easy to change the mounting position of the connecting member 4 and the like. In addition, since it is not necessary to apply a load to the connection portion 41, problems such as a decrease in strength and breakage of the connection portion 41 are less likely to occur.

  Then, as shown in FIGS. 6 to 9, the connecting portion 41 is bent so that the horizontal wire 22 of the lattice body 2 passes through the passing portion 42 of the connecting member 4 to close the space between the front plate 5 and the back plate 6. The fastening bolt B is screwed from the bolt insertion hole 51 of the front plate 5 of the connecting member 4 to the female screw hole 61 of the back plate 6, and the inner surfaces of the front plate 5 and the back plate 6 are in contact with the intersecting portion 23. If the fastening bolt B is tightened until the connecting member 4 and the left and right lattice bodies 2 are fixed, the connecting operation is completed. Since the front plate 5 and the back plate 6 are integrally manufactured via the connection portion 41, the front plate 5 and the back plate 6 are compared with the conventional metal fittings in which the front plate 5 and the back plate 6 are separate. Are less likely to be displaced in the front-rear direction and the left-right direction, and the fastening bolts B are not loosened even after installation, and the positional displacement and fluttering of the lattice body 2 due to the loosening are less likely to occur.

  In this embodiment, as shown in FIG. 1, the connecting members 4 are used in the upper, middle and lower stages of the left and right grid bodies 2, but according to the height dimension of the grid bodies 2 and the grid spacing of the horizontal wires 2 of the grid bodies 2. Thus, the attachment position and the number of attachments of the connecting member 4 may be changed as appropriate.

  Since the fence P according to the present invention can easily connect the left and right grid bodies 2 via the connecting member 4, it is possible to improve the workability of the fence P and further connect the grid bodies in the left-right direction. Even in the existing fence, it can be suitably used to connect the lattice bodies.
