Concrete prestressed steel strand threading guide device with high cable treading efficiency

Abstract

The invention relates to the technical field of building construction and discloses a concrete prestressed steel strand threading guide device with high cable treading efficiency. The device comprisesa pre-embedded anchor base mounted at the end part of a cable threading pipe, wherein the side wall of the pre-embedded anchor base is fixedly connected with a fixing base through a plurality of bolts, the fixing base is provided with a mounting hole, and a first guide pipe is inserted into the mounting hole; the side wall of the fixing base is provided with a fixing mechanism for mounting the first guide pipe, one end of the first guide pipe extends into the pre-embedded anchor base, and the inner side wall of the end, away from the pre-embedded anchor base, of the first guide pipe is provided with an annular connecting groove; the interior of the connecting groove is slidably connected with a connecting pipe, the top of the connecting pipe is provided with a plurality of first limitinggrooves which are uniformly distributed, and the top of the first guide pipe is provided with a mounting groove. According to the concrete prestressed steel strand threading guide device with the highcable treading efficiency, the length of a reserved steel strand can be conveniently changed, and the first guide pipe is conveniently separated from the fixing base.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a threading guide device for concrete prestressed steel strands with high cable threading efficiency. Background technique [0002] For some large buildings, in order to increase the strength of the concrete structure, it is often necessary to use prestressed steel strands to anchor the concrete. During the concrete pouring process, a certain number of cable pipes are pre-embedded in a specific direction, and then a plurality of steel strands are threaded into the cable pipes by using a steel strand threading machine, and finally the anchorage is used at the mouth of the cable pipes. The strands are tensioned. [0003] After retrieval, the Chinese patent application number is 201610038378.X, which discloses a steel strand threading guide device, including a conduit that is docked with a pre-embedded anchor seat at the end of the pre-embedded cable pipe, and the gap...
