Description

Connecting apparatus of composite pile

The present invention relates to a composite pile joining device, and more particularly, to a composite pile joining device for connecting joints of steel pipe piles of various diameters and thicknesses in accordance with design conditions in connecting steel pile piles to the upper part of a PHC pile.

Generally, the pile foundation is one of the basic types adopted when the depth of the supporting layer is deep, and it is possible to stably support the weight of the structure in the supporting layer by constructing the upper structure on the pile inserted into the supporting layer.

Concrete piles, steel pipe piles, and composite piles are used as piles for pile foundation. Concrete pile refers to RC pile, PHC pile, PC pile and so on. It has the advantage of high end bearing capacity due to the closed end of the pile itself, and it is advantageous to reduce the construction cost because the material cost is 2 ~ 3 times cheaper than steel pipe pile have.

The steel pile pile is uniformly resistant to load over the entire length of the pile, and is particularly resistant to bending moment and shear force. Furthermore, after the penetration into the ground is completed, the excess of the pile protruding over the surface of the ground can be cut and reused, thereby minimizing the material loss. However, steel pipe pile has 2 ~ 3 times higher material cost than general concrete pile, which is a disadvantage that it takes a lot of construction cost.

In order to maximize the advantages of the concrete pile and the steel pipe pile, a synthetic pile having a steel pipe welded to the upper end of the concrete pile is provided.

That is, the synthetic pile has advantages of lowering the construction cost by using the concrete pile having low endurance and low cost of the pile, and connecting the steel pipe pile having high resistance to the pile with high moment and shear force have.

These composite piles are welded with steel pile piles to the seat plate attached to the concrete pile, so that the concrete pile and the steel pipe pile are integrally formed.

However, when the concrete pile and the steel pipe pile are welded together as described above, the strength due to the welding is different according to the skill level of the worker and the climatic condition, so that the durability of the pile is varied according to the skill of the worker. There is a problem that the labor cost is high.
