Technical Field

[0001] The utility model relates to the technical field of prefabricated beam and column construction, in particular to a prefabricated beam and column integrated connection structure. Background Art

[0002] Precast beams and columns refer to fixed columns made of concrete. They are building components that are prefabricated, manufactured, and processed in factories. They not only have high strength and high precision, but also have fast construction and production speeds and stable quality. They are widely used in the construction of modern buildings. When precast beams and columns are transported to the construction site for assembly and installation, an integrated connection structure is required to connect and install the precast beams and columns.

[0003] However, when the prefabricated beam-column integrated connection structure is used to connect and fix the prefabricated beams and columns, after the prefabricated beams and columns are connected using the integrated connection structure, the connection position of the connection structure is generally directly exposed to the outside. During later use, not only is it easy for a large amount of dust to accumulate on the outside of the connection structure, making it inconvenient for later maintenance and disassembly, but the exposed connection structure has no protection on the outside, and it is easy to cause deformation and damage to the connection structure when it is hit by external objects. There are deficiencies, and it is not convenient to protect the outside of the integrated connection structure when it is installed and used.

[0004] Now, a new prefabricated beam-column integrated connection structure is proposed to solve the above-mentioned shortcomings. Utility Model Content
