Hoisting ring manufactured by using prestressed concrete steel strand tailings

Abstract

The invention discloses a hoisting ring manufactured by using prestressed concrete steel strand tailings, which relates to a constructional engineering component. The hoisting ring consists of the steel strand tailings, hydraulically upset anchoring ends, steel wire circular rings which bind the tailings and a precast member, and is characterized in that: the hoisting ring of a concrete precast member (4) is manufactured by upsetting the end parts of the prestressed concrete steel strand tailings (1), binding iron wire circular rings (3) with the hydraulically upset anchoring ends (2) and binding the iron wire circular rings (3) at an intersection (5) of the steel strand tailings (1). In the invention, the hoisting ring for hoisting and mounting various concrete precast members is manufactured by utilizing the high mechanical properties of the prestressed steel strand tailings, such as high strength, high flexibility, no brittle failure and the like, so waste materials are changed into valuable materials and useful steel products can be greatly saved.

Description

technical field [0001] The invention relates to a construction engineering component, in particular to a suspension ring of a prefabricated concrete component using the tail material of a prestressed concrete strand. Background technique [0002] In recent years, with the development and standardization of steel strands for high-strength and low-relaxation prestressed concrete, it has greatly promoted the rapid development of large-span prestressed concrete components or structures in China, especially the prestressed concrete components manufactured in Changxiantai Factory. Such as prestressed concrete double T slabs, prestressed concrete hollow slabs, etc. have been widely popularized and applied. Due to the outstanding cost-effectiveness of such components (low sagittal height, large coverage area, high installation efficiency, and good overall stability), it has posed a huge challenge to the traditional large-slab roof system of roof trusses in my country.

AI Technical Summary

Problems solved by technology

[0003] However, the production of prestressed concrete components by Changxiantai will inevitably produce tails of prestressed steel strands of different lengths and lengths after the components are stretched, because they can no longer be used as usable wires for concrete components, and are usually disposed of as waste.
