Abstract

An integrated binding and locating device of single-box double-chamber full span box girder reinforcing steel bar comprises two lines of inner tire frames disposed on ground longitudinally; the device is characterized in that each line of inner tire frames comprises two lines of longitudinally distributed tubular fixing piles, supporting legs inserted between the two lines of tubular fixing piles, two lines of longitudinal platforms fixedly disposed on the supporting legs, two lines of longitudinal chutes detachably connected to upper surfaces of two lines of platforms, and a line of supporting frames disposed on the two lines of chutes; the side walls of the chutes are provided with location holes; the supporting frame comprises four vertical rods with adjustable heights, connecting rods connected between two adjacent vertical rods, pulleys connected to the lower ends of the four vertical rods, and #-shaped frameworks fixedly connected to upper ends of four rods. The device is a reinforcing steel bar binding auxiliary tool which enables the integrated binding of single-box double-chamber box girder to be faster, the location thereof to be more precise, and the assembling and disassembling thereof to be simpler; and the device has the advantages of simple operation, exact location and high working efficiency.

Description

technical field [0001] The invention relates to the construction field of a single-box double-chamber full-hole box girder, in particular to an inner tube frame used in the construction of a single-box double-chamber full-hole box girder. Background technique [0002] The overall binding method of prefabricated box girder steel bars has been widely promoted in the construction of box girders. In the steel bar binding, the inner tube frame is mostly fixed by scaffolding or angle steel and bolts, so the installation and disassembly are cumbersome and the work efficiency is very low. Contents of the invention [0003] The purpose of the present invention is to provide a single-box double-chamber full-hole box girder steel bar integral binding positioning device to solve the problems of cumbersome installation and disassembly of the inner tube frame used in the single-box double-chamber box girder steel bar binding, low work efficiency and poor stability technical problem. ...
