Description

Technical Field

[0001] The utility model relates to the technical field of steel cages, and more specifically to an assembled modular steel cage. Background Art

[0002] Steel cage usually refers to the steel bar components used to reinforce and enhance the strength of concrete in precast concrete structures. Its main function is to increase the tensile strength and bearing capacity of concrete structures. It is usually used in the foundations, columns, beams and other parts of bridges, tunnels and large buildings.

[0003] Long bars are the main longitudinal reinforcement in the cage, responsible for bearing the tensile force. They are usually large diameter steel bars, precisely arranged and connected according to the engineering design requirements. Cross bars are used to fix and connect the long bars, and also have the function of enhancing the overall rigidity of the cage. They are usually thin diameter steel bars, arranged along the circumference of the cage or crosswise according to the required position.

[0004] When two steel cages are assembled and connected, the two steel bars to be connected are generally connected through threaded sleeves. Therefore, it is necessary to open threads at the end of each steel bar, which is more troublesome. The two corresponding steel bars need to accurately maintain the same vertical direction, otherwise the threaded sleeves will be misaligned and difficult to install and connect. When connecting, the threaded sleeves need to be manually rotated for preliminary connection, and finally the threaded sleeves are tightened using a tool similar to a ratchet wrench. The assembly process is complicated, the assembly requirements are high, and the labor intensity of workers is high. Utility Model Content
