Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] Such as figure 1 It shows a specific embodiment of a steel bar connection anchoring sleeve connector of the present invention, including a connecting sleeve 1, and a plurality of annular grooves 8 are arranged on the inner wall of the connecting sleeve 1 to increase the grouting material and the sleeve. The shearing force of the pipe wall is provided with a grouting port 4 at one end of the connecting sleeve 1 and an exhaust port 5 at the other end, whi...

The invention discloses an anchoring sleeve connecting piece for steel bar connection. The anchoring sleeve connecting piece comprises a connecting sleeve, wherein a plurality of annular grooves are formed in the inner wall of the connecting sleeve; a grouting opening is formed in one end of the connecting sleeve, and an exhaust opening is formed in the other end of the connecting sleeve and is used for grouting operation after steel bars are riveted; and the two ends of the connecting sleeve are used for inserting the steel bars and are sealed through sealing device pieces. The anchoring sleeve connecting piece has the advantages that the anchoring sleeve connecting piece is suitable for end connection of all special-shaped steel bars, the application range is expanded, the steel bars deviating from cores can be connected, the structure is more compact, and construction connection is more convenient.
Description
technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a steel bar connection anchor sleeve connector. Background technique [0002] Prefabricated buildings have been gradually promoted in my country since 2015. At present, new buildings across the country have higher requirements for assembly rates, and the demand for prefabricated components will increase. [0003] At present, there are mainly three methods for the connection of steel bars in prefabricated prefabricated components: 1 / mechanical sleeve connection; 2 / grouting sleeve connection; 3 / overlapping of reserved steel bar length. [0004] The mechanical sleeve connection is convenient, but the tolerance for the deviation of the steel bars at both ends is low, and there are many specifications and models. When connecting different types of steel bars at both ends, special processing is required. [0005] Most of the existing grouting sleeve connectors a...
