CONNECTING STRUCTURES AND METHODS BETWEEN FRP DECKS, AND DECK AND GIRDER FOR TUBULAR DECK UNIT WITH HYBRID CONNECTION OF SNAP-FIT AND BONDING

摘要

PURPOSE: A connection structure and method of a bottom plate and a girder using adhesive mixing assembly and a snap-fit between fiber reinforced composite material deck tubes are provided to improve the integrity of a structure by using mechanical connection in a snap-fit form in a vertical direction and chemical connection with an adhesive in a horizontal direction. CONSTITUTION: A connection structure of a bottom plate and a girder using adhesive mixing assembly and a snap-fit between fiber reinforced composite material deck tubes comprises the following steps: laterally connecting fiber reinforced plastic (FRP) deck tubes to form a bottom plate and arranging the same on a girder (100) to integrally connect; equipping first and second downward protrusion joint parts and an upper part expansion part at one side of an FRP deck tube and equipping first and second upward protrusion joint parts and a lower part expansion part at the other side of the FRP deck tube; forming protrusions on the protrusion joint parts to mechanically interlock the protrusion joint parts with each other and vertically inserting the FRP deck tube to connect the upward protrusion joint part to the downward protrusion joint part into a snap-fit form; and joining the upper part expansion part to an upper cross section reduction part and the lower part expansion part to a lower cross section reduction part.
