ARCH STRUCTURE USING CORRUGATED STEEL PLATE AND CONSTRUCTION METHOD THEREOF

摘要

Provided by the present invention is an arch structure using a corrugated steel plate, which comprises: an internal assembly (100) which is formed in an arch structure by multiple assembling operations for an internal corrugated steel plate (110) having a plurality of circular coupling holes (111) so that a cross section in a longitudinal direction forms a wave pattern; a waterproof layer (200) which is formed by coating the outer surface of the internal assembly (100) with a waterproof material; an external assembly (300) which is installed to cover the outer surface of the waterproof layer (200) by multiple assembling operations for an external corrugated steel plate (310) penetrated with a plurality of long hole type coupling holes (311) so that a cross section in a longitudinal direction forms a wave pattern; and a plurality of coupling members (400) which is combined with the circular coupling holes (111) and the long hole type coupling holes (311) in order to form a mutual coupling of internal corrugated steel plates (110), a mutual coupling of external corrugated steel plates (310), and a coupling between the internal assembly (100) and the external assembly (300). By the above composition, the present invention is able to: correct construction errors caused by a curvature difference between the internal corrugated steel plate and the external corrugated steel plate even if a construction is performed by overlapping the plurality of corrugated steel plates; and solve waterproofing problems caused by perforation works.
