Problems solved by technology

[0003] However, the straight threaded connection of steel bars achieves thread self-locking by facing the top of the two connected steel bars. In the connection of steel parts, especially the connection of steel cages and steel mesh pieces, the position of the steel bars is relatively fixed and cannot be rotated. It is impossible to achieve self-locking of the thread on the top, and the residual deformation of the connecting piece is difficult to control, which cannot meet the construction requirements and bury hidden dangers to the quality of the project

Abstract

The invention discloses a self-locking double-sleeve straight thread sleeve connecting structure which comprises a straight thread sleeve, a double-shoulder straight thread screw sleeve, a single-shoulder straight thread screw sleeve and a lock nut. A first reinforcing steel bar component with a first reinforcing steel bar screw head is connected with one end of the straight thread sleeve through the double-shoulder straight thread screw sleeve; a second reinforcing steel bar component with a second reinforcing steel bar head is connected with the other end of the straight thread sleeve through a single-shoulder straight thread sleeve, and the single-shoulder straight thread sleeve is locked in the straight thread sleeve through a lock nut. According to the invention, the first reinforcing steel bar component part and the second reinforcing steel bar component part are stably connected in the straight thread sleeve through the double-shoulder straight thread screw sleeve, the single-shoulder straight thread screw sleeve and the lock nut by utilizing the butting and locking performance of the end face of the straight thread screw head, that is, the thread self-locking connection of the reinforcing steel bar connecting piece is achieved by adopting a split combination mode, the construction is simple and convenient, and the construction efficiency is improved. Quality detection is convenient and visual, and popularization and use are facilitated.

Description

technical field [0001] The invention relates to the technical field of steel bar connection construction in construction engineering, and more specifically relates to a self-locking double-set straight thread sleeve connection structure. Background technique [0002] Straight thread connection of steel bar is the main method of steel bar connection in the current building construction. With the advancement of building industrialization, the steel bar parts have a tendency of large-scale development. [0003] However, the straight threaded connection of steel bars achieves thread self-locking by facing the top of the two connected steel bars. In the connection of steel parts, especially the connection of steel cages and steel mesh pieces, the position of the steel bars is relatively fixed and cannot be rotated. It is impossible to achieve thread self-locking on the top, and the residual deformation of the connecting parts is difficult to control, which cannot meet the constru...
