Description

Steel beam concrete beam hinge structure Technical Field The utility model relates to the technical field of building reinforcement, in particular to a steel beam concrete beam hinge structure. Background In modern building construction, the connection of steel beams and concrete beams is one of the common structural forms. The connection mode not only can fully exert the respective mechanical properties of steel and concrete, but also can improve the overall stability and bearing capacity of the structure. After traditional girder steel and concrete beam's connection, owing to lack bearing structure in the bottom behind the girder steel installation for the bending resistance of girder steel is limited, when bearing great load, the girder steel appears bending deformation easily, influences the overall stability of structure, because girder steel and concrete beam's tie point is concentrated in a certain region generally, causes stress concentration phenomenon easily, and stress concentration can accelerate the fatigue damage of connecting portion, reduces the life of structure, consequently we propose girder steel concrete beam hinge structure. Disclosure of utility model In order to solve the technical problems, the utility model provides a steel beam concrete beam hinge structure. The steel beam concrete beam hinge structure is realized by adopting the following technical scheme that the steel beam concrete beam hinge structure comprises a concrete beam, wherein a high-strength bolt is arranged in the concrete beam, a fixing plate is inserted into the right end of the high-strength bolt, a first nut is connected with the right end of the high-strength bolt in a threaded manner, a connecting plate is fixedly connected with the right end of the fixing plate, a steel beam is arranged at the rear end of the connecting plate, fastening bolts are inserted into the connecting plate and the inner wall of the steel beam, a second nut is connected with the front end of the fastening bolt in a threaded manner, and a reinforcing component is arranged at the bottom of the steel beam. Through above-mentioned technical scheme, install fixedly through high strength bolt and first nut to the fixed plate, then install the girder steel on the connecting plate through fastening bolt and second nut, play the reinforcement effect to the concrete beam, be convenient for install simultaneously.
