Finished steel strand bundle

Abstract

The invention discloses a finished steel strand bundle. The finished steel strand bundle structurally comprises a steel strand bundle, marking plates, a binding iron wire, bundling steel belts and a tractor, wherein the tractor comprises a sleeve; a taper hole is formed in one end of the sleeve; three clamping sheets with the same structure are assembled in the taper hole in one end of the sleeve; the outer diameters of the three clamping sheets are in a taper ring shape; the inner rings of the three clamping sheets are sleeved on the steel strand bundle; an internal thread hole in the other end of the sleeve is connected with one end of a traction head; a hanging ring is arranged at the other end of the traction head; the size of the outer contour of the tractor is smaller than the inner diameter of a construction pore channel through which the finished steel strand bundle penetrates by subsequent traction. The finished steel strand bundle has the beneficial effects that the traction end of the finished steel strand bundle is gradually clamped through the tractor under the action of taper fit between the sleeve and the three clamping sheets; the tractor and the finished steel strand bundle can be firmly locked into a whole body through the hanging ring; meanwhile, the clamping sheets effectively prevent the traction head from slipping in a traction process; the marking plates display the position of each single steel strand, and the pre-stress tension effect is good.

Description

technical field [0001] The invention relates to a finished steel strand bundle in building construction. Background technique [0002] In the construction of buildings, roads and bridges, it is often necessary to pass multiple prestressed steel strands into the prepared prestressed tunnels. However, in the existing technology, after the steel strands are transported to the construction site, the construction personnel cut and process the steel strands according to the required length, and then pass the single steel strands through the prestressed tunnel one by one. The problems in this way are: 1. When multiple steel strands are threaded in the tunnel, they will cause mutual twisting and winding. After the threading is completed, the steel strands at both ends are generally difficult to correspond one by one. When the prestressed anchorage is installed for tensioning, the stress between the steel strands is easy to be uneven, which will cause the deviation of the prestressi...

AI Technical Summary

Problems solved by technology

The problems in this way are: 1. When multiple steel strands are threaded in the tunnel, they will cause mutual twisting and winding. After the threading is completed, the steel strands at both ends are generally difficult to correspond one by one. When the prestressed anchorage is installed for tensioning, the stress between the steel strands is easy to be uneven, which will cause the deviation of the prestressing data after tensioning, which will affect the use effect

2. Each steel strand in the multiple steel strands is marked with a number, and after the threading is completed, the corresponding anchor is installed according to the number; the above steps are cumbersome, and it is difficult to ensure that each steel strand is installed when the anchor is installed. The line corresponds to the anchor positioning holes at both ends, which is very inconvenient for on-site application
