Abstract

The invention provides a steel strand insertion guiding device, and belongs to the technical field of engineering. The steel strand insertion guiding device comprises a main body, a guiding head, a movable sleeve and a plurality of locking pins. The main body is provided with a center hole, a plurality of threading holes and a plurality of connecting holes, the threading holes are circumferentially distributed in the main body at intervals with the center hole as the center, and the threading holes communicate with the center hole through the connecting holes. The guiding head is provided with a center shaft, the guiding head covers one axial end of the main body, the center shaft extends into the center hole, and an annular groove is formed in the center shaft. The locking pins are movably arranged on the main body. The movable sleeve is rotationally connected to the body in a sleeving mode, and the movable sleeve is constructed to push the locking pins to move relative to the main body when the movable sleeve rotates relative to the main body, so that the locking pins extrude steel strands penetrating into the threading holes, and the steel strands are sunken into the annular groove through the connecting holes. According to the guiding device of the structure, the multiple steel strands can penetrate into a prestressed duct of an engineering structure component through one-time strand penetrating, and the strand penetrating efficiency is effectively improved.

Description

technical field [0001] The present application relates to the technical field of engineering, in particular to a steel strand insertion guide device. Background technique [0002] Prestressing engineering is to apply pre-tension stress to the steel strands in the tension module before the engineering structural components bear external loads, so as to improve the stiffness of the components, delay the time of cracks, and increase the durability of the components. [0003] In prestressing engineering, it is necessary to insert multiple steel strands into the prestressing channel of engineering structural components (such as bridges). In general, the prestressed channel is long, and a guide device needs to be installed at one end of the steel strand. The guide device can play a guiding role, so that the steel strand can pass through the prestressed channel smoothly without obstacles. [0004] At present, the guide device can generally only be installed on one steel strand, an...
