Precast box beam reinforcement binding mold and installation method thereof

Abstract

The invention discloses a precast box beam reinforcement binding mold. The precast box beam reinforcement binding mold comprises a base plate,extension rods, pulleys, a frame, a groove, T-shaped plates, reinforcement placing grooves, a middle plate, triangular plates and a traction block, and is characterized in that the frame and the T-shaped plates form a top plate reinforcement skeleton; the T-shaped plates are fixedly mounted at the two ends of the frame; the T-shaped plates are provided with multiple reinforcement placing grooves arranged in an arithmetic progression manner; the middle plate is fixedly mounted on the frame; the top plate reinforcement skeleton is fixedly mounted on the base plate; the base is provided with the groove; chutes are formed in the two sides of the groove;the triangular plates are mounted in the two chutes; the traction block is fixedly mounted on the base plate; the extension rods are fixedly mounted at four corners of the lower top surface of the base plate; and the pulleys are mounted on the four extension rods. The precast box beam reinforcement binding mold prevents direct machining of reinforcements on a rack to cause pollution of a base plate demolding agent, improves the appearance quality, realizes accurate positioning of reinforcements, is low in workload and high in precision, and controls the pass percent of reinforcement protectionlayers of precast box beams.

Description

technical field [0001] The invention relates to a prefabricated box girder steel bar binding mold and an installation method thereof, in particular to the technical field of bridge construction. Background technique [0002] Prefabricated box girder is the main structural form of the bridge structure, and its intrinsic quality is directly related to the service life of the bridge structure. In the context of standardized construction, strive to implement the tenet of "making standards a habit, making habits conform to standards, and making results meet standards". The use of prefabricated box girder reinforcement binding molds in the prefabricated beam construction process can fully achieve construction standardization and modularization. Streamlined and streamlined operations, and overall improved the construction quality of prefabricated box girders. [0003] At present, the conventional prefabricated box girder reinforcement binding is carried out on the pedestal. First,...

Problems solved by technology

Welding is required when tying the steel bars of the bottom web, which will inevitably pollute the bottom plate and affect the appearance of the finished product; the positioning of the steel bars is mainly controlled by visual inspection, ruler measurement, drawing points, and strip lines, which requires heavy workload and low precision. It is difficult to control the qualification rate of steel bar cover of prefabricated box girder
