Abstract

The invention discloses a U-shaped suspension ring structure, and a U-shaped suspension ring is pre-buried in a prefabricated part and is a U-shaped steel stranded wire. An end part of the U-shaped suspension ring is provided with an extrusion sleeve, and a steel anchor plate is disposed between the extrusion sleeve and the U-shaped suspension ring. A U-shaped suspension ring embedding point of the surface of the prefabricated part is provided with a circular gap, and the exterior of a part, exposed outside the prefabricated part, of the U-shaped suspension ring is sleeved by a casing pipe. The structure provided by the invention is high in tensile strength, can be used for replacing a common steel bar as a suspension ring, achieves the safe hoisting, turning and installation of a heavier prefabricated part, is simple, saves materials, is good in economic efficiency, and is higher in practicality.

Description

technical field [0001] The invention relates to the technical field of mechanical tools for construction, in particular to a U-shaped suspension ring structure. Background technique [0002] In the current prior art, during the hoisting process of prefabricated components, the hoisting rings are usually made of HPB300 grade smooth round steel bars. Since the standard tensile strength of HPB300 steel bar is 300MPa, the tensile strength is average, so when the prefabricated component is heavy, in order to meet the lifting requirements, the design diameter of the lifting ring is large, the amount of material is large, the economy is poor, and the applicability is also poor. [0003] Therefore, those skilled in the art are devoting themselves to the development of the U-shaped ring structure. Since the standard tensile strength of the prestressed steel strand is 1860MPa, which is high in tensile strength, it can replace ordinary steel bars and be embedded in prefabricated compon...
