  When a large number of construction surface lining mats are laid on the construction surface to form a large area lining floor, the construction surface lining mat is cut in half at the laying edge and laid on the construction surface. However, it is necessary to determine the end.

  As in Patent Literature 1, when the connecting wire forming the connecting tool is embedded so as to extend on the vertical center line or the horizontal center line of the rectangular construction surface covering mat, the connecting wire crosses each other. In addition, when the mat for the construction surface lining is cut in half, the connecting wire must be cut, and not only is the work required for cutting, but the connecting joints at both ends are separated by cutting the connecting wire. However, there is a problem that the connection strength between the mats is impaired.

Also, it is difficult to provide the necessary number of connecting joints at the required positions of the cut mat.
The above problem is the same when the connecting wire is arranged in parallel with the vertical center line or in parallel with the horizontal center line.

A second connection joint is provided at the end, and the first connection joint is disposed on one side forming the corner, and the second connection joint is disposed on the other side forming the corner. The connecting tool formed by the strip material and the first and second connecting joints is arranged in a square partition region defined by the horizontal center line and the vertical center line of the construction surface covering mat, and the first and second It was set as the structure which aims at the connection with the mat | matte for an adjacent construction surface covering with a connection coupling.

  The connecting strip was held in a mounting groove formed on the lower surface of the construction surface covering mat.

  Further, the connecting strip was embedded in the construction surface covering mat.

  The construction surface lining mat has a vertical joint groove and a lateral joint groove intersecting each other on the upper surface, and the joint strip is formed in the lower joint portion of the longitudinal joint groove portion and the lateral joint groove portion. It was set as the structure extended in hook shape along the part.

  According to the present invention, the mat can be easily cut on the vertical center line, the horizontal center line, or a line parallel to this without interfering with the connecting strip of the coupler, and the connecting strip can be cut without cutting. A divided mat or a quadrant mat can be obtained.

  In addition, a connecting joint can be provided on the vertical side and the horizontal side of the cut two-divided mat or four-divided mat (end mat), and a structure in which both connecting joints are connected by a connecting strip can be maintained.
