Background
The assembled concrete building is a concrete structure house building which is designed and built in a field assembly mode by taking reinforced concrete prefabricated parts produced in a factory as main materials. The assembled concrete building has the advantages of high industrialization level, convenience for winter construction, reduction of construction site construction workload, material consumption, reduction of construction site dust and construction waste and the like, and is favorable for achieving the purposes of improving building quality, improving production efficiency, reducing cost, saving energy, reducing emission and protecting environment. With the continuous development and progress of new construction technology and materials, assembled concrete constructions are widely used. In many countries where construction is industrially developed, fabricated concrete construction has undergone long-term experiments and applications, and modern fabricated concrete construction products have been able to highly integrate various functions of construction, and the form and construction of construction are very fine.
At present, the assembled concrete building mostly adopts the concept of 'equivalent cast-in-situ', and is also called as an assembled integral concrete structure. In the assembled frame structure, a cast-in-situ construction mode of beam and column prefabricated nodes is generally adopted. Because the beam column node needs to be cast in situ at the construction site, the system and the construction method thereof cannot form a whole body by the frame structure system itself before the concrete is cast after the node area reaches the strength, the node has no strength and the structure has no rigidity, and the support systems such as a scaffold and the like still need to be relied on, so that the construction cost is not effectively reduced, and the construction site is still very messy.

It is therefore desirable to provide a fabricated concrete building connection node that does not require reliance on a support system.
