Description

Technical Field

[0001] The utility model relates to the field of prefabricated component hoisting accessories, and more specifically, to a concrete prefabricated component hoisting frame assembly. Background Art

[0002] In construction projects, a large number of precast concrete components are often involved. The precast concrete components are connected with the concrete main body to form the entire building structure, thereby increasing the component speed of the entire building, speeding up the construction period and project progress. When installing the precast concrete components, it is necessary to first hoist the precast concrete components to the required height. Therefore, during the hoisting process, a hoisting frame assembly is required to support the precast concrete components. The existing hoisting frame assembly is generally an integral plate or frame structure, which cannot be adjusted according to the volume of the precast concrete components, making it inconvenient to fix different precast components and having poor adaptability. When hoisting precast components with a higher height, the precast components are placed at a high height on the assembly, which is inconvenient for binding and hoisting. At the same time, the existing hoisting frame assembly cannot fix the top of the precast component, which can easily cause the precast component to shake during the hoisting process.
