Active deflection control prestressed beam

摘要

The present invention is by dividing the beam into a plurality of sections along the longitudinal direction in each interval using the stiffener ginjangjae relates to an arrangement and prestressed beam to actively control the deflection as the introduction of a different pre-stress in each section through this. the active control type prestressed beam deflection according to preferred embodiment of the present invention, the parallel to each other, the lower flange of steel beams and these make up the web is H-shaped cross section to connect; The settlement ends at both ends of the steel plate combined beam; Fixing the ends of the steel beam of the steel plate between the beam into a plurality of center reference positions that are symmetrical to each other coupled to the inner side of the stiffener; Multiple ginjangjae been established between the end plate and between the fixing position of the stiffener are symmetrical to introduce a pre-stress on the steel beam; Installed on the upper surface of the lower flange of the steel beam center to center deflecting device the inflection ginjangjae; And when the upper flange of the steel beam and adjacent to the fixation end plate and a stiffener is provided in a plurality of horizontal deflection apparatus for arranging the ends of ginjangjae horizontally symmetric positions to each other than the number of ginjangjae disposed between the end portion fixing plate by increasing the number of ginjangjae disposed between the stiffener and in that to efficiently respond to the bending moment acting on the steel beam. ;
