<p><P>PROBLEM TO BE SOLVED: To provide a floor material fixing structure having high efficiency in machining a floor material, reducing a material cost of a connecting implement and preventing the longitudinal dislocation of the floor material. <P>SOLUTION: Almost horizontal slotted grooves of the same depth are formed in the predetermined height positions of both side end faces of the floor material 1, and a side edge located below the slotted groove is cut in the halfway depth position of the slotted groove on one side to form a cutout recess 6 only at one side edge. Almost the center part of a bottom plate part 10 of the connecting implement 9 formed in approximately crank-shaped cross section having a wide fitting piece part 12 and a narrow fitting piece part 13 at the upper ends of left and right side plate parts, is formed with an insertion hole 16b for inserting a fastening member 15. The longitudinal length of the one side plate part 11a having the wide fitting piece part 12 is lengthened to form a projecting edge part 14, and the connecting implement 9 is fixed to the side end face of the floor material 1 by the fastening member 15 inserted through an insertion hole 16a of the projecting edge part 14. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
