Building frame beam steel bar overhead installation tool and method thereof

Technical Field

The invention relates to the technical field of building construction, in particular to a tool and a method for mounting a building frame beam and a steel bar overhead.

Background

In domestic building construction, a steel bar binding construction process is mature, but when steel bars of a frame beam are bound, especially when the steel bars of a girder (with the cross section size of about one meter) are bound, some problems still need to be solved.

Two beam frame beam reinforcing steel bar binding process methods are generally adopted in ordinary construction: one technological method is that beam reinforcing steel bars are directly bound in situ on a beam after a beam bottom plate template is laid, the method is mainly limited by operation space, and workers often have difficulty in binding construction under the conditions of binding two rows of bars at the bottom of a girder, binding beam side waist bars, missing and rectifying stirrups and the like, so that potential quality hazards are left, and the construction period is particularly consumed due to the limitation of space; the other process method is that square timbers or steel pipes are adopted to be padded under lower reinforcing steel bars at the bottom of a beam, a beam reinforcing steel bar framework is overhead, temporary steel pipe support frames are erected on two sides of the beam reinforcing steel bars, workers can perform reinforcement binding on the upper portion of the beam in situ in an overhead mode, the temporary steel pipe support frames are unstable, the bearing performance of the wood timbers and the steel pipes padded at the lower portion cannot be guaranteed, the beam reinforcing steel bar framework needs to be lifted to the beam in situ by using a tower crane and the like after the binding is completed, the weight of the beam reinforcing steel bar framework cannot be predicted and can exceed the limit lifting value of a tower crane, and therefore, the method has great potential safety hazards; or the worker directly takes out the square wood or the steel pipe at the lower edge, so that the beam directly falls off the beam bottom template, and the safety can not be ensured.
