Abstract
Description
Technical Field
[0001] This utility model belongs to the field of connection device technology, specifically relating to a sleeve bidirectional connection device. Background Technology
[0002] In cast-in-place pile construction, the connection between reinforcing bars in the rebar cage is generally achieved through lap splicing. However, in environments with limited construction space, welding is often used for these connections, which can easily lead to poor welding quality. Currently, some rebar connections utilize sleeves, but these sleeves are generally unsuitable for use in confined spaces. Using existing sleeves can result in issues such as insufficient tightening, inadequate tightening, or over-tightening, posing safety concerns for the connections between reinforcing bars in the cage. Currently, there is a lack of a bidirectional sleeve connection device for connecting the reinforcing bars in the cage, ensuring a secure connection and improving the overall construction quality of the rebar cage.
[0003] Therefore, a new technology is needed to address the lack of a bidirectional sleeve connection device in the existing technology. Utility Model Content
