Description

Technical Field

[0001] The utility model embodiment relates to the technical field of steel bar cage splicing, and specifically to a splicing guide positioner for special-shaped steel bar cages. Background Art

[0002] The main role of the steel cage is the same as the stress of 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 plays a restraining role on the pile concrete so that it can withstand a certain axial tension. During the construction of bridges or high-rise buildings, the foundation may be required to be piled according to the requirements. The method is to use machine punching and water grinding to drill holes, and the hole depth meets the design requirements. Then put the steel cage into the pile hole, and then insert the conduit for concrete pouring. In order to increase the compressive strength of the steel bars, the designer will nest a smaller steel cage inside the steel cage to form a better-firm mother-and-child cage. The two steel cages are welded together to increase the compressive resistance of the steel cage and ensure the firmness of the building. When the smaller steel cage is embedded in the larger steel cage, it is necessary to ensure that the two steel cages are in the same center state to ensure the uniformity of the force of the steel cage. However, the operation is inconvenient and usually requires multiple workers to perform auxiliary work, which affects the labor efficiency of the workers. In view of this situation, a special-shaped steel cage splicing guide positioner is proposed. Utility Model Content
