Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an externally arranged spacing-adjustable column reinforcement binding and positioning device. Background Art

[0002] In the construction of concrete columns, the accurate position of the steel bars is crucial to the bearing capacity and stability of the structure. Adequate coverage between the steel bars and the concrete is a key factor in ensuring the long-term durability of the concrete structure. Correct steel bar positioning can improve the stress performance of the concrete column and enhance the seismic resistance and bearing capacity of the overall structure.

[0003] Traditional methods may require a lot of time and manpower to adjust and position the steel bars, but the use of binding and positioning devices can save time and cost and improve construction efficiency. The binding and positioning device can ensure the correct position of the steel bars and avoid displacement or misalignment when pouring concrete, thereby ensuring that the concrete is fully covered around the steel bars, reducing the possibility of oxidation and corrosion, and improving the durability of the structure.

[0004] Each existing specification of binding and positioning devices can only be used on steel cages of corresponding specifications. Therefore, it is necessary to produce binding and positioning devices of various specifications to meet the needs of column steel cages of different sizes. The material cost is high, the versatility is poor, and it is inconvenient to store and transport, which limits the large-scale application of the binding device. Therefore, a column steel bar binding and positioning device with adjustable specifications is needed. Utility Model Content
