Technical Field

[0001] The utility model belongs to the technical field of binding pier column steel bars, and particularly relates to a mold for binding pier column steel bars. Background Technique

[0002] For various bridges under construction at present, most projects require short construction periods and high quality requirements. At the same time, restricted by conditions such as the weight and external dimensions of the steel bar skeletons of bridge piers, the steel bar skeletons of bridge piers cannot be completely completed on the construction site. The steel bar skeletons of bridge piers need to be completed in a temporary site near the engineering bridge site that is convenient for transporting the steel bar skeletons of bridge piers. The production quality of the steel bar skeletons of bridge piers is the key to the project quality. If the production quality of the steel bar skeletons of bridge piers is poor and the spacing control of the pier column steel bars is not good, it will affect the bearing capacity of the bridge. At the same time, if the steel bar protection layer is too small, after the concrete carbonates, the steel bars inside the concrete will rust, causing the concrete to spall and affecting the service life of the bridge. For this reason, the utility model proposes a mold for binding pier column steel bars. Content of the Utility Model
