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 precast reinforced concrete members, and belongs to the technical field of precast concrete structures. The connecting method is used for connecting a first precast reinforced concrete member and a second precast reinforced concrete member into a whole. The connecting method is characterized in that at least one through hole is formed in the first precast reinforced concrete member; a concrete bulge is arranged on the second precast reinforced concrete member, and the end part of the bulge extends out of an anchored reinforcement bar; the first precast reinforced concrete member is installed, concrete or grouting material is grouted into the hole, then the second precast reinforced concrete member is installed, and all or part of the bulge on the second precast reinforced concrete member extends 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...
