Document Type and Number:
WIPO Patent Application WO/2011/005009
Kind Code:
A2
Abstract:
The present invention relates to an upper part structure for a continuous bridge. The present invention provides an upper structure for a continuous steel composite girder bridge, comprising: a first girder including a first steel girder for supporting a positive moment being applied to the bridge; a third steel composite girder which is prefabricated such that a compressed prestressed third casing concrete is applied to an upper portion of a third steel girder so as to support a negative moment being applied to a first continuous point, and which has one end connected to an end of the first girder in the longitudinal direction; a second girder which includes a second steel girder to support the positive moment being applied to the bridge, and which has one end connected to the other end of the third steel composite girder in the longitudinal direction; and a concrete bridge deck formed on the first girder, the second girder, and the third steel composite girder. The third steel composite girder in which the compressed prestressed casing concrete is applied to the upper portion of the steel girder is installed in the upper portion of the bridge, which is a continuous part of a continuous bridge, to thereby effectively compensate for the negative moment which acts significantly on the upper portion of the bridge in which girders are connected.
