The beam adding method and its reinforcing device by using the steel wire curve arrangement method at the lower end of the beam

摘要

The present invention is installed to install the fixing brackets surround the beam across the beam lower and lower middle part of the lower beam curve by placing the PC steel was placed in the variable birds avoid secondary cracking of the beam due to the fixing bracket and the part acting on the beam end (-), and the lower beam to reinforce the beam with a small tensile force while reducing the moment relates to the reinforcement and the reinforcement beam apparatus using the wire alignment curve, PC in the beam reinforcement comprises a steel wire, with the beam installation brackets are installed on both ends of the fixing doedoe wrapped around the lower beam, PC steel wire installed tension between the fixing bracket and a unit that acts on the PC steel beam ends by curved beams placed on the lower (-) the degree of tension while reducing the moment the PC steel beam bottom to adjust the distance between the PC steel beam and the lower order to fine-tune characterized by variable extensible saddle is installed.
