A kind of box girder web reinforcement positioning device and construction method thereof

Abstract

The invention discloses a box girder web reinforcing bar positioning device and a construction method thereof. The box girder web reinforcing bar positioning device comprises floor support frames and a reinforcing bar binding and positioning frame, wherein a group of floor support frames are arranged in the direction of a vertical beam at intervals, at least one limiting sleeve with a horizontal opening in the direction of a cross beam is connected to one side of the floor support frames, and the suspended reinforcing bar binding and positioning frame is connected to the side of the floor support frames; the reinforcing bar binding and positioning frame is a comb-like frame which is composed of comb back rods and a group of comb-tooth-shaped reinforcing bar binding support rods horizontally connected to the comb back rods, and the distance between the reinforcing bar binding support rods is matched with the distance between box girder web reinforcing bars; at least one limiting rod with the number, size and connecting position matched with those of the limiting sleeves is arranged in the reinforcing bar binding support rods, and the limiting rods are connected to the interiors of the limiting sleeves correspondingly in a horizontally retractable mode. By the adoption of the box girder web reinforcing bar positioning device and the construction method thereof, reinforcing bars can be positioned accurately, operation is easy, the positions of the reinforcing bars are accurate, reinforcing bar framework installation quality can be guaranteed, construction difficulty is reduced, quick hoisting is achieved, and time and labor are saved.

Description

technical field [0001] The invention relates to a construction auxiliary tool and a construction method thereof, in particular to a positioning device for binding steel bars and a construction method thereof. Background technique [0002] The existing box girder web reinforcement needs to be bound and formed on a specific support on the prefabricated beam field before hoisting. Existing positioning devices are generally responsible for supporting and positioning the binding steel bars at the same time, and the supporting part and the positioning part are fixedly connected, the overall stability is poor, and it is easy to cause inaccurate positioning when the box girder web is bound, time-consuming and labor-intensive technical problems. And after the steel bar binding is completed, because the frame body is fixedly connected, the disassembly of the steel bar is loaded down with trivial details, and it is impossible to realize the fast hoisting of the steel bar cage.
