  However, it is necessary to insert the bolt 108 in parallel to the double wire mesh 101. However, the double wire mesh 101 is obstructive, and it is difficult to insert and tighten the bolt 108. is there.

On the other hand, Patent Literature 2 discloses a metal fitting for covering a side portion of a double wire mesh. As shown in FIG. 6, this metal fitting is fitted on both sides of the double wire mesh 201 with a crosspiece 203 having a pair of grooves 232 into which the vertical and horizontal wire members 221 and 222 located on the side of the double wire mesh 201 are fitted. A presser fitting 205 is attached to the inner side surface of the crosspiece 203 so that the vertical wire 221 positioned in the groove 232 is pressed toward the groove 232. Here, the metal fitting 205 is fixed to the crosspiece 203 by screwing in two screws 206, and these two screws 206 are inserted so as to form a letter C in plan view. Therefore, since it can be screwed in from the front surface and the back surface of the double wire mesh 201, the mounting work is easier than in Patent Document 1.
Therefore, it is conceivable to apply the metal fitting of Patent Document 2 as a double metal mesh connecting metal fitting. That is, two double wire meshes 201 are arranged side by side in contact with each other, and the vertical wire members 221 at the ends of the double metal meshes 201 are collectively fitted into the groove portion 232, and the presser fitting 205 is attached so as to press the vertical wire material 221. It is. Thereby, since the vertical wire 221 of the two double metal meshes 201 can be clamped together, the double metal mesh 201 can be connected.

  However, in this case, the screw 206 can be screwed in from the front surface and the back surface, but this does not solve the problem of troublesome installation work. This is because, when the double wire net 201 is fixed to the side portion as in Patent Document 2, the mounting operation is easy, but when the double wire net is connected, the front and back surfaces are not easily accessed.
