Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prestressed tendon tensioning, in particular to a prestressed tendon tensioning shelving tool using a pre-tensioning method. Background Art
[0002] The pre-tensioning method is a construction process that tensions the prestressed tendons before pouring concrete, and temporarily anchors the tensioned prestressed tendons on the pedestal or steel beam, and then pours concrete. When the concrete reaches the specified strength after curing, the prestressed tendons are relaxed and prestress is applied to the concrete. The production of prestressed components using the pre-tensioning method involves pedestals, steel beams, tensioning frames, and tensioning equipment.
[0003] The position of the prestressed tendons is positioned by the reserved holes of the tensioning frame. During tensioning, the tensioning frame is close to the steel beam, and the prestressed tendons are connected to the tensioning wire rods. The tensioning wire rods pass through the reserved holes of the tensioning frame, and then penetrate into the through-type jacks for tensioning. During routine operation, the bottom of the tensioning frame is placed on square wood or channel steel. The tensioning frame is prone to uneven height and tilt, and it is inconvenient to adjust. After each prestressed tendon is tensioned, the position of the jack needs to be adjusted. The through-type jack is directly suspended on the tensioning wire rod, which easily causes the jack and the prestressed tendons to be out of center, and it is not easy to accurately adjust the position of the jack.
