Description

[0001] PILE WELDING EQUIPMENT [0002]

The present invention relates to a file welding apparatus, and more particularly, to a file welding apparatus capable of welding two files (piles).

A pile is a rod-shaped material that penetrates into the ground. A file with the upper half exposed on the ground connects the structure to it. It is usually used as a bridge or as part of a bridge bridge in the water. The foundation pile, which is completely covered in the ground, belongs to a type of foundation work used when the foundation foundation is weak. It is intended to increase the strength of the foundation foundation by bearing the pile on soft ground and to withstand the heavy load placed thereon. Files classified by material include wood files, concrete files, reinforced concrete files, prestressed concrete files, and steel files.

If the file goes deep into the ground, it is sometimes used by connecting two files. In this case, a drilling operation is performed using an excavator or the like, and then two connected files are inserted.

Conventionally, in order to link two files, two files are laid down on the surface of the earth, and then the welded parts of the two files are welded using a welding apparatus. According to the conventional method, since two files are laid down on the ground surface and then work, there is a problem that the work space occupies a lot of the file length. In addition, there is a problem that it requires a long time because one side is welded first and then the file is rotated to weld the non-welded portion.

In addition, conventionally, there is a device in which one file is vertically inserted into the ground and another file is vertically erected thereon, and the abutting portions of the two files are welded. However, the conventional Co2 welding apparatus uses a flux cord wire , A wire having a maximum diameter of 1.6 pia and a diameter of a large diameter is welded at a time of welding, and the welding takes a long time since the welding must be performed twice or more while rotating.

The present applicant was registered on September 18, 2014 after filing a patent application for a file welding apparatus (registration number 10-1444603) for solving the problems of the prior art.
