Technical Field
[0001] The present invention relates to the technical field of prefabricated reinforced concrete structures, in particular to a spliced prefabricated component for assembled buildings. Background Art
[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, and modern wooden structures. Compared with traditional concrete cast-in-place buildings, prefabricated buildings are undoubtedly a major improvement. The prefabricated components of prefabricated buildings can be produced in factories and assembled on-site. The production of prefabricated components can be standardized, quality controlled, efficient and fast, reducing material waste and reducing environmental pollution on the construction site.
[0003] During the construction of prefabricated buildings, the connection of prefabricated components is generally achieved by tensioning and locking with rigid connecting rods or prestressed steel strands. This type of connection method has complex on-site operation procedures and low efficiency. Moreover, prefabricated components require reinforcement, and the reinforcement arrangement is complex, which brings inconvenience to the production, transportation, and installation of prefabricated components. In addition, the connection stability between prefabricated components is the key to ensuring the safety of prefabricated buildings. However, the connection structure between existing prefabricated components has problems such as insufficient connection stability and a cumbersome connection process. In order to solve the above technical problems, those skilled in the art need to design a new type of spliced prefabricated component. Summary of the Invention

[0016] Beneficial effects
[0017] A spliced prefabricated component for assembled buildings manufactured using the technical solution of the present invention has the following advantages:
[0018] 1.
