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 connection method of prefabricated reinforced concrete components and belongs to the technical field of a prefabricated reinforced concrete structure. The connection method includes that a first prefabricated reinforced concrete component and a second prefabricated concrete component are integrally connected. The connection method is characterized in that at least one hole is formed in the first prefabricated reinforced concrete component, rebar is arranged in the holes, and the rebar is anchored in concrete of side walls of the holes; anchor-connected rebar extends out from the second prefabricated reinforced concrete component; the first prefabricated reinforced concrete component is mounted, the concrete or grouting materials are filled in the holes, the second prefabricated reinforced concrete component is mounted, and anchor-connected rebar of the second prefabricated reinforced concrete component is extended into the holes.
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...
