A positioning device for steel bars on bridge deck concrete layer

Abstract

The invention provides a steel bar positioning device for the bridge deck concrete layer, which effectively solves the problems in the prior art that the marking accuracy is poor when the steel bars are laid, the spacing is inconvenient to control and adjust, and the problems are greatly affected by the flatness of the ground surface; the solved technology The solution is to include a rectangular housing, with a driving shaft inside the housing, a first bevel gear at the left end of the driving shaft, a second bevel gear meshing on the upper side of the first bevel gear, and a universal coupling at the upper end of the central shaft of the first bevel gear. A spline shaft is connected, a roller is set on the spline shaft, and a slideway is arranged on one side of the housing; a driving wheel is fixed on the driving shaft, a driven shaft is on the front side of the driving shaft, a driven wheel is on the driven shaft, and a driven wheel A transmission device is installed between the driving wheel and the driven shaft; a cylindrical shell is fixed at the right end of the driven shaft, and there is paint in the cylindrical shell, and a discharge hole is opened on the side wall of the cylindrical shell, and an annular block is set on the outer side of the cylindrical shell, and the annular block is fixed to the shell , the upper and lower side walls of the annular block are provided with vertical through holes.

Description

technical field [0001] The invention relates to the technical field of steel bar positioning, in particular to a steel bar positioning device for a bridge deck concrete layer. Background technique [0002] At present, in the municipal construction, the distance between road and bridge reinforcing bars is generally all manually marked or set out by workers with a scale in the prior art. In this way, manual marking often leads to large errors, resulting in unbalanced forces in local areas, which not only affects the quality of the project, but also affects the progress of the construction and increases the construction cost. [0003] In the prior art, the patent document with application number 201310084749.4 discloses a steel bar spacing marker for building construction, in order to solve the problems of large randomness and insufficient precision in manual marking. It uses the rotation of the wheel to drive the rotation of the spokes. During the rotation, the spokes first p...
