Fabricated repairing and reinforcing apparatus for reinforcing bearing force of beam in a bridge

摘要

If the subject innovation is that the need to increase the is due to aging decrease the compression force that the support load of the bridge beam or bridge the expected crack due to the deflection of the bridge beam superstructure of the bridge the various bracket so as to enhance the load carrying capacity of the bridge beam as used in the construction method of using prefabricated rehabilitation device for reinforcing load-carrying capacity of the bridge beam,; Provided in the lower portion of the bridge beam in the area in which the installation side bracket and a side bracket that is installed as a pair on both sides of the doedoe bridge beam installed at a predetermined distance inside from the respective side end portions of the end bracket and the bridge beam to be installed on both side ends of the bridge beam respectively connected to the rod or strand them as a pair of bottom brackets are installed and welded to the side ratio racquet by introducing a tensile force is prefabricated rehabilitation device to enhance the load carrying capacity for the bridge beam.; A method of using the prefabricated rehabilitation device enhances the load carrying capacity to the bridge beams and respectively connected and fixed to the side bracket and a plurality of connecting steel bars that are installed on both sides the side of the end bracket and the bridge beam is provided on both ends of the bridge beam , and to pass through the through-sphere and connecting side bracket on the bridge beam lifting holes formed in the end side of the bridge beam steel bar of the side brackets provided on both sides of the bridge beam using the nut on the side brackets provided at both sides and the fixing is fixed, the bridge beam to a distance a pair of side brackets that are installed apart on opposite sides steel bar or while connected to install the strand and integrated to the lower bracket and the welding is installed in the same location as the point at which the side bracket in the lower portion of the bridge beam is installed, the lower portion of the bridge beam connecting the rod or strand on the lower bracket installed by a pair sulfonic One after anchorage After adapted to come into close contact by filling a gap between the bridge beam and the end bracket, the side bracket and the lower bracket with epoxy or epoxy mortar, after the introduction of tensile force on the connecting rod and the rod or strand, respectively provided on the bracket using fixed by fixing it to enhance the load carrying capacity by introducing compressive forces on the bridge beam.
