CORRUGATED STEEL SHEET HAVING INCLINED PORTION IN WHICH POSITION OF COUPLING HOLE IS ADJUSTED AND JOINT CORRUGATED STEEL SHEET STRUCTURE USING SAME

摘要

The present invention relates to a corrugated steel sheet, and provides a corrugated steel sheet (B) having an inclined portion in which the position of a coupling hole is adjusted, wherein: among a pair of corrugated steel sheets (A, B), a corrugated steel sheet (B) is overlapped and joined with the upper portion of a lower corrugated steel sheet (A) and has the same thickness as the lower corrugated steel sheet (A); a common bolt is coupled to both a coupling hole in the lower corrugated steel sheet (A) and a coupling hole in the corrugated steel sheet (B); and when assuming that the distance between the center of a middle crest portion coupling hole (111) and the center of an adjacent inclined portion coupling hole (141) is a coupling hole distance (a, b), the coupling hole distance (b) for the corrugated steel sheet (B) is calculated by equation 1. Therefore, the present invention can obtain a stable bolt coupling strength, can minimize the occurrence of a gap in a joint corrugated steel sheet structure in which the corrugated steel sheets are overlapped and joined together, thereby improving the waterproof performance thereof, and can facilitate bolt coupling work, thereby improving constructability on the site.
