Abstract

The invention relates to a prefabricated reinforced concrete member and a manufacturing method thereof, and belongs to the technical field of prefabricated concrete structures. The prefabricated reinforced concrete member is internally provided with at least one non-through hole. The holes are internally provided with rebars anchored in concrete at the bottoms of the holes. The top of each hole is provided with metal foil for sealing the hole. According to the provided manufacturing method of the prefabricated reinforced concrete member, the holes are manufactured by adopting an inner formwork of a steel pipe or a fiber reinforced composite pipe, the bottom of the inner formwork is sealed and provided with a hole, and the rebars penetrate through the hole. By means of the prefabricated reinforced concrete member and the manufacturing method thereof, the mechanical performance of the prefabricated concrete structures is improved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated reinforced concrete structures. Background technique [0002] Prefabricated concrete structures have high production efficiency and good quality, save resources and are conducive to sustainable development. The use of prefabricated concrete structures is the development direction of construction industrialization. [0003] In the prior art, the prefabricated reinforced concrete components are provided with holes, and the reinforced concrete is inserted into the holes to improve the connection between the prefabricated components; at this time, the steel bars are inserted and anchored in the post-cast concrete in the holes, and the post-cast concrete and the precast concrete are close to each other. The bonding force of old and new concrete is connected together, and the connection performance is insufficient. Contents of the invention [0004] The purpose of the invention is to improve t...
