Abstract

The invention provides a high-safety-performance steel strand paying-off device for construction. The steel strand paying-off device comprises a hollow shell body, a cover plate, and a rotating drum;the hollow shell body is open at one end, and a paying-off hole is formed in the sealed end; the cover plate is connected with the open end of the hollow shell body in a detachable mode so a hollow cavity is defined by the cover plate and the hollow shell body; the rotating drum is arranged inside the hollow cavity so a steel strand is wound on the outer wall of the rotating drum; two ends of therotating drum are respectively connected with the hollow shell body and the cover plate in a rotatable mode; an arc-shaped pipe is arranged on the rotating drum and penetrates through the rotating drum; and the arc-shaped pipe communicates with the paying-off hole. Support for the steel strand is realized by the rotating drum, the steel strand is wound on the rotating drum, and constraining forceof the steel strand can be released in advance on the rotating drum, so safety in the paying-off process of the steel strand is guaranteed and the steel strand is prevented from catapulting and injuring a person; the situation that no intertwining or knotting is caused in the paying-off process of the steel strand can be ensured, and paying off is convenient; and smooth paying-off of the steel strand can be ensured and the steel strand can be prevented from being exposed to rain and becoming rusty.

Description

technical field [0001] The invention relates to the technical field of prestressed engineering in construction engineering, in particular to a steel strand pay-off device with high safety performance for construction. Background technique [0002] With the continuous improvement of people's living standards, the construction industry is required to provide comfortable and bright spaces, flexible and changeable plane combinations and bridges with larger spans to meet the various needs of life and work. Prestressed concrete is catering to the development trend of modern building structures with its outstanding advantages such as large span, light weight, saving building materials, saving building height, and improving building and structural functions. However, the steel strands used in prestressing engineering may have the danger of ejection when they are set out due to the binding force. At present, the steel strands used in most construction projects are very simple and hav...
