Device assembly for tensioning fork ear type stay rope or steel pull rod and tensioning construction method of device assembly
The invention provides a device assembly for tensioning a fork ear type stay rope or a steel pull rod. The device assembly comprises a counter-force rack, a tensioning rod, a carrying pole beam and a jack; the counter-force rack is of a similar U-shaped structure and divided into two pieces; the opening of the U-shaped structure is designed into a step shape, and a bolt holes and a tensioning rod semicircular groove I to allow the tensioning rod to pass through are formed in the step; the carrying pole beam is of a split two-half structure, and the stay rope or the steel pull rod is capable of passing through the middle of the split two-half structure, and tensioning rod semicircular grooves II for mounting the tensioning rod are formed on the two sides of the split two-half structure; when the device assembly is applied to tensioning construction, the two pieces of the counter-force rack are mounted on the two sides of the fork ear of the fork ear type stay rope or the steel pull rod and are integrated by use of a bolt and a connecting plate; the two-half carrying pole beam is mounted on the extension cylinder end of the fork ear type stay rope or the steel pull rod and fixed by use of a bolt; the tensioning rod is put through the carrying pole beam and the counter-force rack, and anchored by use of a fixing nut at one end of the counter-force rack; the jack and a base plate are mounted on the other end of the tensioning rod and the other end of the tensioning rod is anchored by use of a tensioning nut; the device assembly is good in safety and high in universality in tensioning construction.
