An arched building structure comprises an arched coupling body, a still plate and a still, which support the arched coupling body on the ground. The arched coupling body is constituted by coupling two curved members with a plate member formed separate from the curved members. Each curved member is constituted by coupling multiple large steel decks bent with roundness in a wave direction. |

DETAILED DESCRIPTION It is therefore an object of the present invention to provide an arched building structure which has a sufficient mechanical strength and can be built easily at low cost.
(1) To achieve this object, an arched building structure according to one aspect of the present invention comprises multiple curved structural members constituted by a corrugated plate bent perpendicular to the wave direction and having a large section modulus, and curved-member coupling means, formed separate from the multiple curved members, for coupling the multiple curved members along the length of the corrugated plate to provide an arched coupling body.
Since this structure uses a corrugated plate with a large section modulus as a structural member, it can sufficiently resist the weight of snow and wind pressure.
Also because the arched building structure can be realized by a combination of the corrugated plates, the structure can be built easily at low cost.
Further, as the curved-member coupling means is formed separate from the curved members, this coupling means can be carried or transported separate from the curved members, thus improving the efficiency of transporting the curved members.
(2) According to another aspect of the present invention, an arched building structure comprises multiple curved members constituted by coupling multiple corrugated plates, each bent perpendicular to the wave direction and having a large section modulus, by flanges provided on wave-directional ends of the corrugated plates, and curved-member coupling means for coupling the multiple curved members in a lengthwise direction of the corrugated plates to provide an arched coupling body.
With this structure, because of the reason given in the section (1) above, an arched building structure has a sufficient mechanical strength and can be built easily and at low cost.
Since the corrugated plates will be coupled by the flange provided at the end portion of the corrugated plate, the coupling job can be done on either the outer or inner surface of the curved member
