For solving the problem that a reinforcing
steel bar bundle is prone to loosen during hoisting, the invention discloses a fixing device for hoisting reinforcing steel bars for
building construction. The fixing device comprises a
lantern ring, wherein a connecting rod is fixedly connected to the top surface of the
lantern ring, a second connecting plate is fixedly mounted at the top end of the connecting rod, a supporting frame is welded to the upper surface of the second connecting plate, a material pump is fixedly installed at the top end in the supporting frame, the discharging end of the material pump communicates with a discharging
pipe, a first connecting plate is fixedly installed on the right side face of a second connecting plate, a material containing box is fixedly installed on the upper surface of the first connecting plate, a first guide
pipe communicates between the material containing box and the material pump, a pull rod is welded to the side face of the
lantern ring, a hoisting ring is welded to the top end of the pull rod, an air bag is sleeved with the lantern ring, and an
air pump is fixedly installed on the lower end face of the lantern ring. According to the fixing device, gaps between the reinforcing steel bars in the
steel bar bundle are filled with
wax liquid, then the steel bars are stably bundled through the air bag, the
steel bar bundle is stably hoisted, and the steel bar bundle is prevented from loosening.
