PRESTRESSED PREFLEXTION H-BEAM AND T-SHAPED PIER CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: A construction method for a T-shaped pier using a prestressed preflextion H-beam is provided to shorten a period of construction and to cut down the construction expenses by a simple construction method and a scale-down of pier section. CONSTITUTION: The construction method for a T-shaped pier using a prestressed preflextion H-beam comprises the steps of: installing an H-beam(13) which forms a column of a pier on the footing ground, then placing concrete to the pier foundation(14); installing an upper T-shaped pier by forming a pier head(11) by connecting a preflextion H-beam(20) to the other end of the H-beam(13) which forms a column of a pier and installing many haunches(15) to a joint between the H-beam(13) and the preflextion H-beam(20); installing a lower T-shaped pier by forming a pier head(11) by connecting the preflextion H-beam(20) on the B-beam(13) which forms a column of a bridge and installing many haunches(15); and installing a double-storied T-shaped pier by placing concrete to the H-beam(13) which forms the pier head(11) and the pier column of the upper, lower T-shaped piers.
