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 reinforced concrete component connecting method, and belongs to the technical field of prefabricated concrete structures. The method includes the step of integrating a first prefabricated reinforced concrete component and a second prefabricated reinforced concrete component, and is characterized in that at least one hole is formed in the first prefabricated reinforced concrete component, filled with retarded adhesive mortar and internally provided with reinforcing steel bars, the reinforcing steel bars are anchored in concrete of the side walls of the holes, concrete protrusions are arranged on the second prefabricated reinforced concrete component, the first prefabricated reinforced concrete component and the second prefabricated reinforced concrete component are installed, the protrusions of the second prefabricated reinforced concrete component completely or partly extend into the holes, and the first prefabricated reinforced concrete component and the second prefabricated reinforced concrete component are integrated after retarded adhesive mortar is cured.
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...
