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 connecting method of a prefabricated concrete member and belongs to the technical field of prefabricated concrete structures. Through the connecting method, a first prefabricated concrete member body and a second prefabricated concrete member body are connected into a whole. The connecting method is characterized in that the first prefabricated concrete member body is provided with at least one non-through hole; steel bars are arranged in the holes; the steel bars are anchored in concrete of the bottoms of the holes; the second prefabricated concrete member body is provided with concrete protrusions; the ends of the protrusions stretch out to be connected with the steel bars in an anchored mode; the first prefabricated concrete member body and the second prefabricated concrete member body are installed; the protrusions of the second prefabricated concrete member body completely or partially stretch into the holes; and the space between the first prefabricated concrete member body and the second prefabricated concrete member body and the holes are filled with concrete or a grouting material
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...
