Description

Technical Field

[0001] The invention relates to the technical field of prefabricated buildings, in particular to a fixed-length binding device for beam and column reinforcement cages used in prefabricated buildings. Background Art

[0002] The main function of the steel cage is the same as the stress on the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It restrains the concrete of the pile body so that it can withstand a certain axial tension. Among them, due to the long length of the steel cage, it is necessary to use the method of tying continuous stirrups around it to enhance its integrity.

[0003] At present, the process of bundling steel cages is mostly carried out directly on the ground. The steel bars are enclosed into a rectangle and then stirrups are tied on it in turn. However, for prefabricated buildings, in order to make the cast beams and columns able to be used together, corresponding connecting components need to be installed at both ends of the beams and columns. It is very inconvenient and difficult to position the steel cages and the combination of the steel cages and the connecting components on the ground. In addition, the length of the steel cages is not easy to measure and determine. Based on this, the present application proposes a fixed-length binding device for beam and column steel cages for prefabricated buildings to solve the above problems. Summary of the invention
