CONNECTING STRUCTURE FOR CORRUGATED METALLIC PLATE MEMBER, CONNECTING METHOD AND TEMPORARY FIXING WASHER

摘要

PROBLEM TO BE SOLVED: To enable a temporary fixing washer closely fitted to a bolt to prevent the bolt from being pulled down out of a bolt insertion hole to be easily inserted to the bolt when the end portions of two corrugated metallic plate members contacted with a ground are connected with bolt.SOLUTION: A bolt 3 is inserted from a ground surface side into a bolt insertion hole 1c of an end part 1f (a crest part p seen from a curved inside) of one corrugated metallic plate member 1 and inserted up to a contacted state to an upper surface of the member under a state in which a temporary fixing washer 5 is flexed to a threaded part 3b protruded above. A bolt temporary fixing hole 7 has semi-circular recess parts 7a and is formed by opposing bolt supporting parts 7b, its both sides are provided with recesses 8. The temporary fixing hole 7 can be expanded under its flexed state and can be easily inserted into the bolt, upon releasing fingers to release the flexed state to attain a flat state, resulting in that the hole inner edge enters into a groove of the thread part of the bolt and engaged with the bolt. Since the temporary fixing washer is flexed to expand the temporary fixing hole and inserted into the bolt, force is hardly required and it can be easily inserted into the bolt.SELECTED DRAWING: Figure 7A
