Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a screw anchor with anti-corrosion performance. Background Technique

[0002] A screw anchor is a basic engineering component, mainly used to provide support and anchoring functions. The screw anchor consists of a central column and one or more spiral blades. It inserts the spiral blades into the ground and uses the friction force and end bearing force between the soil body and the spiral blades to bear the load transmitted from the upper structure.

[0003] The screw anchor is buried underground or in a relatively harsh environment and is easily affected by corrosion, thereby reducing its service life and bearing capacity. Coating an anti-corrosion coating on the surface of the screw anchor is a common anti-corrosion method. The anti-corrosion coating can form a protective film to prevent moisture, oxygen, and corrosive substances from contacting the metal surface.

[0004] In the prior art, the screw anchor has a simple structure and is easy to use. It can provide good support and anchoring functions, reduce the floor area, and reduce the impact on the surrounding environment. However, the drawback is that in actual applications, there are requirements for the length adjustment of the screw anchor and it needs to adapt to different operation requirements. The common splicing methods for increasing the length of the screw anchor require manual welding or flange connection, which is relatively cumbersome to operate and inconvenient to disassemble, thus affecting the operation efficiency. For this reason, a screw anchor with anti-corrosion performance is proposed to solve the above problems. Summary of the Utility Model

A convex block 14 is fixedly connected to the outside of the first anchor rod body 1. The convex block 14 is used to increase the friction force, enhance the anchor fixation, reduce the contact area, and improve the corrosion performance.

[0033] Refer to Figures 1 - 3 , specifically, a plurality of sliders 6 are provided. The plurality of sliders 6 are all slidably connected to the middle of the chute 5. The chute 5 is used to limit the sliders 6 and improve the fixing stability. An inner groove 7 is opened inside the second anchor rod body 2.
