Problems solved by technology

[0002] At present, in the production of precast concrete box girders in China, most of them are constant-section box girders, and variable cross-section beams are rarely involved. Construction, if the formwork is used for a long time, it will not only affect the appearance, but also reduce the construction efficiency and weaken the advantages of segmental beam construction

Abstract

The invention discloses a segmental precast variable-cross-section concrete box beam steel bar binding bed-jig. The segmental precast variable-cross-section concrete box beam steel bar binding bed-jigcomprises a main support, a wing plate fixing support, a web plate fixing support, a bottom plate fixing support, a top plate inner fixing support and a construction platform. The main support comprises stand columns and a stand column transverse connecting beam, the wing plate fixing support comprises a wing plate longitudinal distribution beam, a wing plate transverse distribution beam and a wing plate reinforcing steel bar limiting clamping groove, the web plate fixing support comprises a web plate transverse support, a web plate inclined support, and a web plate reinforcing steel bar limiting clamping groove, the bottom plate fixing support comprises a bottom plate supporting cross beam, a bottom plate adjusting cross beam, a bottom plate reinforcing steel bar limiting clamping grooveand a height adjusting column, a bottom plate reinforcing steel bar limiting clamping groove and multiple longitudinal bottom supporting rods at equal intervals are arranged on the bottom plate adjusting cross beam, the top plate inner fixing support comprises a top plate transverse distribution beam, a top plate longitudinal distribution beam and a top plate reinforcing steel bar limiting clamping groove, and a construction platform comprises safety stairs, a platform connection beam, a platform plate and a railing head. The construction efficiency can be greatly improved, and the construction error is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to a segmental prefabricated variable-section concrete box girder steel bar binding tire frame. Background technique [0002] At present, in the production of precast concrete box girders in China, most of them are constant-section box girders, and variable cross-section beams are rarely involved. For construction, if the formwork is used for a long time, it will not only affect the appearance, but also reduce the construction efficiency and weaken the advantages of segmental beam construction. Contents of the invention [0003] The object of the present invention is to provide a segmental prefabricated concrete box girder with variable cross-section steel bar binding tire frame, so as to improve construction efficiency and reduce construction errors. [0004] The present invention is achieved through the following technical solutions. [0005] A segmental prefabricated concr...
