Technical Field

[0001] The utility model relates to the technical field of precast concrete, in particular to a precast concrete modular component with a high assembly rate. Background Art

[0002] Precast concrete is concrete that is made in a factory or on-site (not in the final design location) to make concrete products. Precast concrete is poured somewhere other than at the final construction site. Precast concrete of different sizes and shapes can be reinforced with fibers to increase its reliability and toughness after cracking.

[0003] When precast concrete modules are in use, as the buildings are built higher and higher, the concrete modules also need to be moved to a higher position for installation. Generally, the precast concrete modules are transported and installed by hoisting. However, due to the shape of precast concrete, it is not convenient to connect the precast concrete parts with the hoisting rope during hoisting, which affects the efficiency and speed of hoisting, thereby affecting the installation efficiency of the precast concrete parts.
