Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a square pile mechanical connector. Background Art

[0002] With the increasing importance and height of modern buildings, higher requirements are being placed on the bearing capacity of foundations. Concrete piles are used as foundation piles. Compared with concrete pipe piles, square piles have a larger surface area as foundation piles. This means that square piles can withstand greater loads than pipe piles under the same geological conditions. However, the existing square pile connection method does not have significant advantages compared to pipe pile connection methods. Piles are fixed together by welding with connecting flanges, which takes a long time and requires high welding quality. The connection is exposed to the geological layer for a long time, and the weld surface is easily corroded by groundwater. In severe cases, the connection may break, reducing the safety of the square piles. To this end, we propose a mechanical connector for square piles. Summary of the Invention
