The invention discloses aconnecting joint of an upright post and a steel bent cap and a construction method thereof. The connecting joint comprises an outer steel pipe, a top covering plate and the upright post; the upright post comprises a concrete post, longitudinal main reinforcementsand a concrete stirrup; the outer steel pipe which is arranged on the post surface, connected to the one end ofthe steel bent cap, of the upright postcovers part of the concrete post, the longitudinal main reinforcementsare connected with the inner side of the outer steel pipe in a welded mode, the top covering plate which is arranged at the top end of the outer steel pipe covers a post end surface, and the steel bent cap is arranged on the top covering plate and is fixedly connected with the top coveringplate. The construction method comprises the steps of installing prefabricated steel templates and measure pipes in sequence, pouring ordinary concrete in the measure pipes, installing the outer steelpipe and the top covering plate in sequence, pouring micro-expansive concrete in the outer steel pipe, and finally detaching the steel templates and finishing construction. According to the connecting joint of the upright post and the steel bent cap and the construction method thereof, the technology is simple, the construction time is short, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of municipal elevated engineering, in particular to a connection node of a column and a steel cover beam and a construction method thereof. Background technique [0002] The portal elevated structure generally adopts the structural form of cast-in-place columns and concrete cover beams. The construction of the concrete cover beams of this portal elevated structure can only be carried out after the construction of the columns, which is time-consuming during construction; the construction of concrete cover beams needs to be erected Formwork and bent frames, the construction process is complicated, and the construction cost is high; after the construction of the concrete cover beam is completed, it will take more than 20 days of maintenance time, which further prolongs the construction period. [0003] As the requirements for rapid construction become higher and higher, more and more portal elevated structures ...
