Corrugated steel sheet having inclined portion in which position of coupling hole is adjusted and joint corrugated steel sheet structure using same

Abstract

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 corrugatedsteel 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.

Description

technical field [0001] The present invention relates to a construction field, more specifically, to a corrugated steel plate structure. Background technique [0002] Compared with concrete structures, building structures using corrugated steel plates have the advantages of being light in weight, excellent in workability, and able to reduce air and cost, and therefore, researches on applications are actively being conducted. [0003] The existing corrugated steel plate comprises: a W-shaped main body 100 with a central top 110, two connecting tops 120, two valleys 130 and four inclined parts 140; connecting holes 111, 121, 131, 141 are respectively formed in a The central part of the central top 110, two connecting tops 120, two valleys 130 and four inclined parts 140 ( Figure 1 to Figure 7 ). [0004] According to international standards, the depth (D) of the main body 100 is 237 mm, the pitch (P) of the main body 100 is 1000 mm, and the curvature R of the top 110 and the ...

Problems solved by technology

[0013] Therefore, the bolts of the above-mentioned standard (diameter 22mm) cannot be fastened, and when using smaller diameter bolts, stable bonding strength cannot be obtained, and when the size of the connection hole is increased, there is a problem of leakage through the extra space
