Description

GUIDER FOR CONCRETE FILE}

More particularly, the present invention relates to a guiding device for connecting a pile file to a pile file. More particularly, the present invention relates to a guiding device for guiding a pile of pile files, And can remove moisture generated around the welded portion in real time.

Normally, the reinforcing plate is welded to the inner circumferential surface of the steel pipe file, the cover plate is welded to the upper end of the steel pipe file, and the steel pipe is welded around the lid plate.

This requires laborers to individually weld the cover plate and the rebar in the field, which increases labor and production costs.

Further, welding heat causes deformation, cracks, weakening of the texture and corrosion of the welded portion.

In addition, there is a problem that welding may be dropped due to a small welding area, and the structure may be damaged due to a weak vertical load.

There is also a bolt-type steel pipe pile head reinforcement method. This is accomplished by piercing a number of bolt holes on the side of the steel pipe with hydraulic air, inserting the bolt-type steel pipe pile head reinforcement cover plate into the steel pipe, assembling the bolt on the side of the steel pipe file, Assemble the lower cast iron and the reinforcement bar, fasten the normal rebar and screws to the circular cover plate, assemble the reinforced base of the expanded base and pour the concrete.

This is because there is no on-site welding process and the use of a prefabricated cover plate is expected to shorten the construction time, but it is difficult to carry and transport the cover plate.

Further, a cruciform reinforcing plate is inserted into the inside of the steel pipe and welded to the inside of the steel pipe, the circular lid plate and the steel pipe pile head are welded to each other, and a plurality of vertical reinforcing bars are fillet welded around the outer side face of the steel pipe pile, Assemble the rebar and place concrete on it.

This is because the steel pipe file does not require concrete filling to the inner side, but it is difficult to weld the steel pipe in the field, and it is difficult to assemble the reinforced foundation steel, transportation is difficult, and construction cost is high.
