Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a combined steel bar connection joint. Background Art

[0002] Steel reinforcement engineering is a very important part of the construction industry, especially in large-scale buildings and special projects, such as nuclear power projects, where its quality, efficiency and cost have received great attention.

[0003] In the prior art, the most common steel bar connection sleeve is a mechanical connection among steel bar connection methods. It has the characteristics of energy saving and is not limited by the composition and type of steel bars. The steel bar sleeve, also known as the steel bar joint, is a connector used to connect steel bars and has an internal thread corresponding to the thread head thread. The ends of the steel bars are first processed into straight threads by rolling technology, and the two steel bars are connected to each other with the corresponding connection sleeve.

[0004] However, when the existing connecting sleeve is used to connect two steel bars, the steel bars need to be rotated to make them threadedly connected with the connecting sleeve. When installing the second steel bar, one end of the first section of the steel bar has been installed on the connecting sleeve structure. When the connecting sleeve is rotated, the first section of the steel bar will also rotate with it, thereby affecting the installation of the second section of the steel bar. Especially when one end of the connected steel bar is longer, the installation is more laborious and easily restricted, resulting in reduced installation efficiency.

[0005] The traditional method of connecting steel bars with sleeves is usually inefficient and error-prone, and cannot meet the needs of modern construction projects.

[0006] In view of the above factors, it is urgent to develop a new, efficient and reliable steel bar mechanical connection structure. Utility Model Content
