Problems solved by technology
The connection nodes between components in the existing prefabricated concrete structure are generally the weak link of the structure, which affects the mechanical performance; at present, the reinforcement connection between the upper and lower prefabricated components of the prefabricated structure adopts the reinforcement sleeve grouting connection, the grout anchor connection, etc., the construction process Complex, construction quality is not easy to guarantee
[0003] The connection between existing prefabricated components is generally to reserve steel bars in the lower components and insert them into the upper components. For example, steel sleeve grouting connection, grout anchor connection and other technologies anchor the lower wall reinforcement in the upper wall. Grouting requires pressure. The quality of grouting is not easy to guarantee, and the construction is more complicated

The invention relates to a prefabricated-concrete-member connection method, and belongs to the technical field of prefabricated concrete structures. According to the prefabricated-concrete-member connection method, a first prefabricated concrete member and a second prefabricated concrete member are integrally connected; the connection method is characterized by including the steps that at least one hole which is not through is formed in the first prefabricated concrete member, and reinforcing steel bars are arranged in the hole and anchored in concrete on the side wall of the hole; concrete protrusions are formed in the second prefabricated concrete member, and anchor-connection reinforcing steel bars extend out of the ends of the extrusions; the first prefabricated concrete member is installed, the hole is filled with concrete or grouting materials, then the second prefabricated concrete member is installed, and the protrusions of the second prefabricated concrete member fully or partly extend into the hole.
Description
technical field [0001] The invention belongs to the technical field of prefabricated reinforced concrete structures and is suitable for assembling integral concrete structure systems. Background technique [0002] Prefabricated concrete structure is a structural form suitable for industrialization. The connection structure between prefabricated components in the assembled monolithic precast concrete structure determines the overall performance of the structure. The connection nodes between components in the existing prefabricated concrete structure are generally the weak link of the structure, which affects the mechanical performance; at present, the reinforcement connection between the upper and lower prefabricated components of the prefabricated structure adopts the reinforcement sleeve grouting connection, the grout anchor connection, etc., the construction process Complex, construction quality is not easy to guarantee. [0003] The connection between existing prefabric...
