Abstract

The invention relates to a prefabricated concrete member and a manufacturing method of the prefabricated concrete member and belongs to the technical field of prefabricated concrete structures. At least one discontinuous hole is formed in the prefabricated concrete member. Rebars anchored into concrete at the bottoms of the holes are arranged in the holes. The manufacturing method of the prefabricated concrete member includes the steps that the holes are manufactured through inner dies of steel pipes or fiber-reinforced composite pipes, the bottoms of the inner dies are sealed and provided with the holes, and the rebars penetrate the holes. By the adoption of the prefabricated concrete member, the stress performance of the prefabricated concrete structure 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 precast concrete structures is the development direction of the construction industry. [0003] In the prior art, prefabricated concrete components are provided with holes, and steel bars are inserted into the holes and concrete is poured to realize the connection between prefabricated components. The concrete bonding 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 concrete components, improve the integrity of the prefabricated concrete structure, and propose a prefabricated concrete component and a manufacturing m...
