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 hole. The holes are internally provided with rebars anchored in concrete on the side walls 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, groove channels are formed in the surface of the inner formwork, and the rebars are placed in the groove channels. 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, 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, prefabricated reinforced concrete components have holes, and reinforced concrete is inserted into the holes to realize the connection between prefabricated components. The connecting steel bars are anchored in the post-cast concrete in the holes, and the post-cast concrete and precast concrete are combined by old and new concrete. The force is connected together, and the connection performance is insufficient. Contents of the invention [0004] The purpose of the present invention is to improve the connection performance between prefabricated reinforced...
