Provided is a tension locking force self-equalized hollow spherical hinge of multi-beam anchor rods or anchor cables and a construction method thereof. The spherical hinge comprises a counterforce anchor tool, a hollow jack, a spherical hinge spherical body and a spherical hinge spherical shell. The spherical hinge spherical shell is fixedly connected with the hollow jack through a fixed piece, and the spherical hinge spherical body is embedded in the spherical hinge spherical shell. The top face of the spherical hinge spherical body is higher than the top face of the spherical hinge spherical shell, and pins are inserted in the higher part of the spherical hinge spherical body. The end portions of the pins are attached to the top face of the spherical hinge spherical shell, and the spherical hinge spherical body and the spherical hinge spherical shell are respectively provided with through holes which rightly face middle holes in the hollow jack. The technical problems that existing multi-beam anchor rods or anchor cables are pulled down due to the fact that each anchor rod or each anchor cable bears different pull force in the tensioning process, and uniform force bearing of all anchor rods or anchor cables can not be achieved are solved. The spherical hinge can be widely applied to tensioning process of the anchor rods or the anchor cables, and particularly suitable for even tensioning of the multi-beam anchor rods or the anchor cables.
Description
technical field [0001] The invention relates to an anchor rod or anchor cable tensioning device and a construction method, in particular to a multi-bundle anchor rod or anchor cable tensioning device and a construction method. Background technique [0002] With the rapid development of my country's economy, the construction of various buildings is in the ascendant. Prestressed bolt construction technology is widely used in various types of foundation pit support. During the tensioning and locking process of multi-beam prestressed anchor rods (cables), hollow jacks are generally used for tensioning. [0003] However, the process of directly using hollow jacks for tensioning has the following two obvious defects: (1) safety accidents are prone to occur; (2) time-consuming, labor-intensive, and inefficient. [0004] 1. Safety accidents are prone to occur [0005] The direct use of hollow jacks for tension ensures that the displacements of the ends of each steel bar (strand)...
