THE SIMULTANEOUS CONSTRUCTION METHOD OF GROUND AND UNDERGROUND STRUCTURE USING GROUND CORE PRE-CONSTRUCTION AND LATTICED LINTEL BEAM IN CORE

摘要

PURPOSE: A combined construction method of ground and underground structures using an inner latticed lintel beam of a core and a ground core part built in advance is provided to minimize rest processes and improve constructability by minimizing the amount of temporary installation parts in the core. CONSTITUTION: An inner latticed lintel beam of an underground core(10) comprises longitudinal latticed lintel beams(110) and transverse latticed lintel beams(120). The longitudinal latticed lintel beams and the transverse latticed lintel beams are installed in an inner elevator area of a core and a stair area longitudinally and transversely. The latticed lintel beams are installed to be extended to the perimeter wall girder of the core continuously or discontinuously. The opened part of a core wall is installed to be opened in advance.
