Abstract

The application discloses a kind of bolt ball node net rack structure rod piece field replacement auxiliary device and method, it is related to bolt ball node net rack technical field, including rod piece body and field replacement auxiliary assembly, the both ends of rod piece body are provided with bolt ball end piece, field replacement auxiliary assembly is set to the four around of rod piece body, the inside of the threaded hole is provided with screw rod, the force transmission connecting ring is arranged between the square clamping plate and bolt ball end piece, the surface of screw rod is connected with fastening nut by thread.The bolt ball node net rack structure rod piece field replacement auxiliary device and method, screw rod is loosened by loosening fastening nut, so that rod piece body can be removed to replace it, so that the replacement operation of rod piece body is facilitated by assembly type connection, and the pre-tightening force when fastening nut is tightened is calculated by calculating internal force control equipment or program, so that the internal force of rod piece body after replacement is more in line with original design requirements by controlling internal force, and the secondary distribution of force is reduced.
