RIGID JOINT STRUCTURE BETWEEN THE PRECAST CONCRETE COLUMN AND THE LONG-SPAN PRECAST CONCRETE GIRDER, AND THE CONSTRUCTION METHOD USING THE EXTENSION PRECAST CONCRETE BRACKET

摘要

The present invention relates to a structure in which a long-span PC girder is rigidly joined to a PC column and a construction method for constructing the same. It is located on the opposite side of the contact surface and the column contact surface and is connected to the PC girder and consists of a first upper contact vertical surface, a lower contact surface, and a L-shaped cross section each having a first lower contact surface, and is placed on the upper surface of the mounting bracket. , The PC girder has a trench with an open upper portion and inner walls formed at both ends in the longitudinal direction, and both ends of the PC girder have a second upper contact vertical surface and a second upper contact surface corresponding to the L-shaped cross-section of the extended PC bracket. It is characterized in that it has a L-shaped cross section each having a lower vertical surface, and is connected to the extended PC bracket to form a long-span PC girder. Long span can be promoted while minimizing the
