Abstract

The invention provides a reinforcing steel bar self-locking connector and a self-locking connecting method. The connector comprises a cylinder plug, a lock cylinder and bayonet lock units, wherein the cylinder plug comprises a first reinforcing steel bar connecting section and a lock cylinder connecting section, a plurality of bayonet lock holes are formed in the lock cylinder connecting section, and each bayonet lock hole is matched with one bayonet lock unit; each bayonet lock unit comprises a bayonet lock pin which can move back and forth along the corresponding bayonet lock hole; the lock cylinder comprises a second steel bar connecting section and a cylinder plug connecting section, the cylinder plug connecting section is of a hollow structure, and the end face, away from the lock cylinder, of the cylinder plug connecting section is open; and a plurality of clamping teeth arranged in the length direction of the cylinder plug connecting section are arranged on the inner wall of the cylinder plug connecting section, and gaps between the adjacent clamping teeth are matched with the corresponding bayonet lock pin to form a self-locking state. Reinforcing steel bars with the anchoring length do not need to be reserved, bonding and anchoring are completed without relying on grouting materials, and mounting of a prefabricated concrete member is facilitated; and meanwhile, the connection mode is mechanical force connection, so that the problems of aging and failure of chemical grouting connection are solved, and the reliability of reinforcing steel bar connection is improved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, in particular to a steel bar self-locking connector and a self-locking connection method. Background technique [0002] Construction industrialization represents the development direction of my country's construction industry. The prefabricated structure can realize modern control and fully automated production during the construction process, which has a good role in promoting the development of my country's construction industrialization. Solving the problem of steel bar connection is the key to solving the problem of the integrity of the assembled structure. On the basis of ensuring the excellent connection performance of the joint, research on a more reasonable joint structure and sleeve production process can reduce the cost of the steel bar connection joint and increase the construction speed. It is of great significance to promote the industrialization of construction. The ...
