Coreless screw anchor

Abstract

The invention relates to a coreless screw anchor which is characterized by comprising a coreless screw blade, a connecting pipe and a connecting plate, wherein a notch is formed at one end of the coreless screw blade; one end of the connecting pipe is inserted into the notch; and the connecting plate is connected with and mounted at the other end of the connecting pipe. The coreless screw anchor has the advantages that the coreless screw anchor can adapt to various soil and lower the use cost.

Description

technical field [0001] The invention relates to a ground anchor, in particular to a helical ground anchor without a mandrel. Background technique [0002] At present, ground piles supporting buildings mainly include concrete piles and steel piles, and steel piles are further divided into H-shaped piles and steel pipe piles according to their shapes. Concrete piles are suitable for any building, while steel piles are mainly used for light construction. However, concrete piles require maintenance, long construction period, damage to surface vegetation, and poor environmental protection. Therefore, steel piles are mainly used in light buildings (including vegetable greenhouses, solar support, etc.). The steel pile obtains the supporting force through the frictional force between its surface and the soil in the vertical direction. This supporting force is relatively small, which limits the application range of the steel pile. Now, there is a kind of helical ground pile with a ...

AI Technical Summary

Problems solved by technology

However, its helical blades are easily deformed when encountering relatively hard ground, which limits the range of soil used; moreover, this kind of helical ground pile with a mandrel requires a special pile driver to complete the piling installation, which greatly increases the cost of use
