Connecting method of precast reinforced concrete members

Abstract

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 groove is formed in the first precast reinforced concrete member, and the groove is filled with the retarding mortar; a reinforcement bar is arranged in the groove, and is anchored into concrete at the side wall of the groove; a concrete bulge is arranged on the second precast reinforced concrete member, and the end part of the bulge extends out of the anchored reinforcement bar; the first precast reinforced concrete member and the second precast reinforced concrete member are installed, and all or part of the bulge of the second precast reinforced concrete member extends into the groove; after the retarding mortar is cured, the first precast reinforced concrete member and the second precast reinforced concrete member are connected into a whole.

Description

technical field [0001] The invention belongs to the technical field of prefabricated reinforced concrete structures, and is suitable for assembling an integral concrete structure system. Background technique [0002] Precast concrete structure is a suitable structural form for industrialization. The connection structure between the prefabricated components in the prefabricated monolithic precast concrete structure determines the overall performance of the structure. The connection nodes between the components in the existing precast concrete structure are generally the weak links of the structure, which affect the mechanical performance. At present, the steel bar connection between the upper and lower prefabricated components of the prefabricated structure adopts steel sleeve grouting connection, grout anchor connection, etc., the construction process Complex, construction quality is not easy to guarantee. [0003] The connection between the existing prefabricated componen...

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
