Reinforcement connection assembly and concrete reinforcement connection system and construction method thereof

Abstract

The invention discloses Rebar connection components and their Connection system and construction method, steel bar connection assembly, the connecting steel bar includes an extension part and an expansion part, the sleeve has an open end and a closed end, the extension part of the connecting steel bar passes through the closed end of the sleeve, so that the expansion part of the connecting steel bar Located in the sleeve, one end of the connecting rod is expanded and deformed to form a thickened end. The peripheral wall of the connecting rod is provided with a plurality of extrusion blocks that are in contact with the peripheral wall of the connecting rod, and the extrusion block is arranged on the side away from the connecting rod There is a metal spring ring, the metal spring ring is coaxial with the connecting rod, and all the extrusion blocks are extruded and bound on the peripheral wall of the connecting rod through the metal spring ring. The outer diameter of the metal spring ring is larger than the inner diameter of the sleeve. The metal spring ring is squeezed on the inner diameter surface of the sleeve in the way of interference fit, and there is a gap A between the expansion section of the connecting steel bar and the inner wall of the sleeve, and the lower sleeve plug is located in the gap A and is consistent with the shape of the gap A .

Description

technical field [0001] The invention relates to a concrete reinforcement connection system composed of a reinforcement connection assembly and a reinforcement connection assembly, and a construction method thereof. Background technique [0002] In house construction, the most common concrete connection method is the connection relationship between concrete member B and concrete member A. For concrete, steel bars are first used to connect, and then concrete is poured. This construction technology requires on-site construction, so the construction period is long, and it also increases the construction period of the existing house. Therefore, in order to reduce the construction period, prefabricated concrete components can be used B and concrete member A are under construction, however, how to connect the two has become a major bottleneck in existing construction. Contents of the invention [0003] The object of the present invention is to provide a concrete reinforcement co...
