PURPOSE:To easily join sheets by a structure wherein one rope for joining sheets is run in advance through a ring part provided at the end of a spring steel wire grip part constituting the joining link and the other rope is placed on the grip part and slipped down in the ring part by pivoting the joining link. CONSTITUTION:The edges 9 and 10 of sheets 7 and 8 are lapped one upon the other. After that, a plurality of engaging tongues 11 and 12 are fixed in the vicinity of the edge 10 of the sheet 8 and of the upper edge 9 of the sheet 7. The ropes 13 and 14 are independently engaged onto the engaging tongues 11 and 12 respectively and disposed in tension and the rope 13 is run in advance in the ring parts 4 of the joining links 6. Then, when the rope 14 is placed on the side of the grip part 2 set in horizontal state and then the joining link is pivoted upward 100-150 deg. about the ring parts 4, the ring part 4 is pulled outward by the rope 13 and at the same time the rope 14 is slipped down to the end 3, resulting in pulling the end 3 outward and consequently producing gap between a tip 5 and the end 3 in order to let the rope 14 into the ring part 4. After that, the two ropes 13 and 14 are joined each other by returning the joining link 6 to the horizontal state. The sheets 7 and 8 can be joined together by performing above-mentioned joining means several times. |
