Description

  The present invention relates to a connecting member for connecting two grid-like panels and a fence connected to the panels via the connecting member.

  In a fence combining struts and grid-like panels used as a means for partitioning road boundaries, site boundaries, etc., a free-column fence that directly connects adjacent panels is used. . In this system, vertical members and / or cross members of adjacent panels are sandwiched from the front and rear using two connecting fittings, and the connecting fittings are fastened with bolts and nuts to connect and fix the left and right panels. However, as described above, since at least three members of two connecting brackets and fixing bolts are used, the vertical and / or horizontal members of the two adjacent edges of the panel are aligned, and the front and rear fixing brackets are further aligned. Since it is necessary to attach the fixing bolt while adjusting the hole position of the fixing bolt, the operation is troublesome.

  Therefore, in Patent Document 1, in a mesh body connection structure for connecting two mesh bodies, a first connector having a screw insertion hole and a groove-like portion extending linearly, and a first connector having a screw hole and a recess. And fitting the groove portion of the first connector to the horizontal line of each mesh member, and the vertical portion of each mesh member in the recess of the second connector device. As the wire penetrates, the male screw inserted into the screw insertion hole is screwed into the screw hole and tightened, and each net-like body is held between the first connection tool and the second connection tool. A network connection structure has been proposed.

  Further, in the present applicant, as shown in Patent Document 2, in a mesh fence in which a mesh panel formed in a lattice form is attached to a support column, vertical members at two adjacent edges of the mesh panel are attached.
