[0002] Precast concrete refers to concrete that is made into concrete products in a factory or on-site. Precast concrete is poured elsewhere rather than at the final construction site. Precast concrete of different sizes and shapes can use fibers to enhance its reliability and toughness after cracking. There are many types of precast concrete. The various styles and weights plus excellent flexural strength and performance make it widely used in roadblocks, water tanks, exterior walls, construction and decoration. One of them is the beam-column node structure.

[0003] At present, the beams and columns of prefabricated assembled concrete structures are all prefabricated in factories, and the connection between beams and columns generally adopts the method of secondary casting on site.
