PREFABRICATED CONCRETE ARCH RIB AND IT'S CONSTRUCTION METHOD

摘要

It is designed to provide a kind of precast concrete arch rib and its construction method, it can pass through no Construction of Supporting in economical cost by building precast concrete arch rib assembly precast concrete arch blocks, precast concrete arch blocks and small span and above-mentioned large span are constructed, building arch rib is able to bear very big load. In order to achieve the above object, Prefabricated Concrete arch rib according to the present invention includes: multiple precast concrete arch blocks; PS steel is perforated in precast concrete arch blocks through-hole; PS steel is inserted into PS steel through-holes respectively; Apply precast concrete arch blocks that there is scheduled thickness on high-tension fiber bonding layer or steel mesh adhesive layer. In addition, in order to reach the goals above, Prefabricated Concrete arch rib construction method according to the present invention, comprising steps of being mounted on abutment or bridge pier using claims 1 or 2 as defined in PS steel situation precast concrete arch ribs on the casting bed of the concrete prefabricated arch rib of the first Tensing to form the interim assembled state of precast concrete arch rib; The precast concrete arch rib that the steel precast concrete arch rib state of the second Tensing PS temporarily assembles is elevated by crane, to assemble precast concrete arch rib completely; With installation precast concrete arch rib on abutment or bridge pier. ;The 2014 of copyright KIPO submissions
