Technical Field

[0001] This utility model belongs to the field of precast component hoisting technology, specifically relating to a matching hoisting tool for hoisting precast components. Background Technology

[0002] Prefabricated structure is short for prefabricated concrete structure. It is a concrete structure that is assembled and connected with prefabricated components as the main load-bearing components. With the increasing development of prefabricated structure, the hoisting of prefabricated components will become a routine construction process.

[0003] Conventional lifting tools and pre-embedded round steel bars, after use, are cut out using gas welding. This process presents challenges in corrosion prevention and results in poor surface finish at the cut areas. Therefore, finding a way to reuse lifting tools while ensuring lifting safety has become paramount. Utility Model Content

[0006] The pre-embedded bolt assembly includes a head sleeve and threaded studs, with an anchor bar fixedly connected to one end of the head sleeve.

[0007] Furthermore, the lifting rings are arranged in a figure-eight shape.

[0008] Furthermore, the anchor bars are distributed at equal angles along the axial centerline of the end cap sleeve, which facilitates the firmness of the anchor bars after installation.

[0009] Furthermore, the end cap sleeve and the threaded stud are connected by threads, which facilitates hoisting operations.

[0010] Furthermore, a limiting block is provided at one end of the threaded stud, and the threaded stud is connected to the groove through the limiting block, which facilitates the fixing of the threaded stud.

[0011] Furthermore, the pre-embedded bolt assembly also includes a threaded cap that mates with the threaded end cap sleeve, which facilitates sealing the end cap sleeve by means of the threaded cap when the prefabricated component is not hoisted.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0013] (1) By setting up lifting rings, baffles, hooks, grooves, embedded bolt assemblies, end cap sleeves, anchor bars, threaded studs and threaded caps, prefabricated components can be effectively hoisted. Furthermore, the embedded structure is convenient, quick to install and dismantle, and reusable, thereby effectively improving the overall hoisting efficiency. Attached Figure Description
