Title:
CONSTRUCTION METHOD OF STEEL COMPOSITE GIRDER BRIDGE
Document Type and Number:
WIPO Patent Application WO/2011/093556
Kind Code:
A1
Abstract:
The present invention relates to a construction method of a steel composite girder bridge, and more specifically, to a construction method of a steel composite girder bridge in which a non-composite section is kept on a cast-in-place slab when pre-stress is introduced, and non-shrinkage mortar is filled at the position of a shearing connector for serving as a composite section after the pre-stress is introduced. The construction method of a steel composite girder bridge according to the present invention comprises the steps of: mounting steel girders continuously formed with shearing connectors to be separated by a predetermined distance at pier sections; mounting shores and first forms to the steel girders for concrete slab casting; mounting non-composite members to the upper flanges of the steel girders at the non-composite sections of supports, and mounting second forms around the shearing connectors; forming support slabs by disposing sheath pipes to the supports and pouring and curing concrete, and forming shear pockets at the positions of the shearing connectors with the second forms; introducing pre-stress into support slab sections via the sheath pipes and carrying out grouting; forming span slabs by pouring and curing concrete to span sections between the pier sections and filling the non-shrinkage mortar into the shear pockets; and forming a road and mounting protection fences after removing the shores and the first and second forms.
