Description

Technical Field

[0001] The utility model relates to the technical field of steel bar binding of prefabricated components, in particular to a steel bar binding positioning device for prefabricated components. Background Art

[0002] Box girders of reinforced concrete structures are divided into prefabricated box girders and cast-in-place box girders. Box girders prefabricated in an independent site can be erected in combination with a bridge erection machine after the lower part of the project is completed, which can speed up the project progress and save construction time. At present, most prefabricated box girders are cast using standardized steel formwork, and the top plate of the box girder is a load-bearing structure that directly bears the bridge deck load. The control of the spacing of steel bars is an important link in ensuring the overall structural strength of the box girder. During the process of binding the top plate steel bars of the box girder, the overall construction quality and progress of the box girder are seriously affected due to problems such as low steel bar spacing accuracy and difficulty in installing and removing the comb plate.

[0003] In the existing construction of prefabricated box girder projects, the top plate reinforcement of the box girder is mostly tied directly on the outer formwork of the prefabricated box girder after the inner formwork of the prefabricated box girder is installed. This process uses a comb plate bolted to the outer formwork as a reinforcement tying device. When the inclination angle of the top plate of the box girder or the longitudinal spacing of the top plate reinforcement changes, the comb plate on the steel formwork needs to be punched and fixed again according to the arrangement of the top plate reinforcement, which consumes a lot of labor, materials and construction progress. In addition, during the concrete pouring process, since the bolt connection part of the comb plate is located on the outer formwork and close to the pouring port, the concrete slurry easily invades the bolt connection part, making it difficult to disassemble the comb plate, which seriously affects the on-site construction progress and fails to achieve the purpose of improving the accuracy and efficiency of the top plate reinforcement tying of the box girder.

[0004] The Chinese patent with the authorization announcement number CN220945950U applied by the applicant recently discloses a box beam top plate reinforcement binding device, which includes a support frame, a mobile unit arranged at the bottom of the support frame, a vertical plate arranged on the support frame, a plurality of groups of strip vertical grooves opened on the vertical plate, a plurality of bottom plates respectively slidably locked on these groups of strip vertical grooves by first fasteners, a pair of trapezoidal end plates respectively fixed to the two ends of the bottom plate by second fasteners, a pair of comb plates respectively fixed to the upper waist surface and the lower waist surface of the trapezoidal end plates by third fasteners, and a top plate fixed to the pair of trapezoidal end plates by fourth fasteners. Although the above-mentioned reinforcement binding device has the advantages of easy installation and removal of the comb plates and is suitable for limiting the top plate reinforcement arranged at different inclination angles and spacings, it occupies a large volume and has a high manufacturing cost, which needs to be improved.
