Problems solved by technology

[0003] However, when using positive and negative threaded sleeves, the connected steel bars will be displaced. When using clip-type split sleeves, the two connected steel bars are not easy to be on the same straight line, resulting in reduced construction quality; at the same time, reduced construction efficiency

Abstract

The invention relates to a connecting device and a construction method. The connecting device comprises a connecting sleeve and a positioning assembly. Internal threads are formed in the inner circumferential wall of the connecting sleeve, external threads matched with the internal threads are formed in the outer wall of the positioning assembly, and the positioning assembly is inserted into the connecting sleeve and is in threaded connection with the connecting sleeve; a threaded hole is formed in the positioning assembly, and the positioning assembly is used for being in threaded connection with two steel bars to be connected; and the construction method comprises the steps that a first steel bar is connected with a first fixing unit, a second steel bar is connected with a second fixing unit, the first fixing unit is connected with the second fixing unit, and the connecting sleeve is connected with the positioning assembly. According to the connecting device and the construction method, the connecting sleeve is in threaded connection with the positioning assembly, the connecting sleeve is used for locking the positioning assembly, displacement of the two steel bars is avoided, meanwhile, it is guaranteed that the joint of the two steel bars is not squeezed, and therefore the construction quality and the construction efficiency are improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of threaded sleeves, in particular to a connection device and a construction method. Background technique [0002] At present, a sleeve connection is often used between two steel bars. Among them, the sleeves used for the mechanical connection of steel bars are widely used with positive and negative threaded sleeves and clip-type split sleeves. [0003] However, when the positive and negative threaded sleeves are used, the connected steel bars will be displaced. When the clip-type split sleeves are used, the two connected steel bars are not easy to be on the same straight line, resulting in reduced construction quality; at the same time, reduced construction efficiency. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a connecting device and a construction method, which has the advantages of improving the construction qualit...
