CONNECTION STRUCTURE OF PRECAST CONCRETE COMPOSITE FRP DECK UNITS AND PRECAST CONCRETE COMPOSITE FRP DECK HAVING SUCH CONNECTION STRUCTURE

摘要

A continuous structure of precast concrete composite FRP(fiber reinforced plastic) deck units is provided to continue adjacent precast concrete composite FRP(fiber reinforced plastic) deck units integrally with simple and economic method. Disclosed is the continuous structure of precast concrete composite FRP(fiber reinforced plastic) deck units(10) composed of a lower frame(11) manufactured with FRP(fiber reinforced plastic) and provided with an upper plate(111) and a lower plate(112), and hollows(114) formed by a partition(113) formed between the upper plate and the lower plate, and a precast concrete slab(12) placed in a factory and formed on the upper part of the FRP lower frame integrally. The FRP deck units are integrated with each other laterally by inserting an insertion of the FRP lower frame of the composite FRP deck unit into upper and lower projections of the FRP lower frame of the adjacent composite FRP deck units to make the upper and lower projections cover the insertion, and applying adhesives such as epoxy between the inside of the upper and lower projections and the outside of the insertion to join the upper and lower projections with the insertion integrally.
