Description

H-beam section steel pile drawing device {H-beam pulling system}

The present invention relates to a pulling device for pulling out H-beam section steel piles embedded in the ground, and more particularly, by improving the engagement structure of the section steel pile pulling device, when pressing the H-beam section steel pile with a pressing member, the central part and both sides of the wing are At the same time, the H-beam shape steel pile is not deformed by the interlocking pressing member and the H-beam section steel pile is not deformed and can be drawn more easily by making the pressing member wider and at the same time having a firm engagement. -It relates to a beam-shape steel pile drawing device.

Conventionally, a number of drawing devices have been provided for drawing (pulling out) H-beam shaped steel piles embedded in the ground at a construction site.

However, since both sides of a conventional H-beam section steel pile are meshed with a pressure member to be pulled out, the position where the pressure member is engaged with the H-beam section steel pile is limited, so there is a problem that the biting part of the pressure member slides during drawing, and this is solved. To do this, by increasing the pressing force of the cylinder of the pressing member, there is a problem that the wings of both sides of the H-beam shaped steel pile are crushed inward, resulting in deformation.

Looking at the prior art in this field, "Seal Steel Pile Extractor" (hereinafter referred to as "Prior Technology 1") of Registered Patent Publication No. 10-1080962 (registration date November 1, 2011) refers to a section steel pile extractor. A lower frame in which a space into which the section steel pile is inserted is formed in the center of the unit, and the lower end of the rising cylinder is fixedly installed in the front and rear sides of the upper surface; An upper frame having a space corresponding to the space formed in the lower frame, wherein upper ends of the lifting cylinder are provided through both sides of the lower surface in front and rear, and cutouts are formed at both sides of the space into which the shape steel piles are inserted; A plurality of fixing members arranged between the upper and lower frames and connecting the upper and lower frames; A connecting member that connects the upper ends of the lifting cylinders exposed to the upper side of the upper frame, but has an open side toward the space into which the shape steel pile is inserted; An upper side is exposed through the cutout portion and connected to the connection member disposed on both front sides, and a lower side is an interlocking member positioned on the upper side of the lower frame; And a pressing member disposed on the upper side of the pressing frame, the upper side of which the lower side of the interlocking member is installed, and a pressing plate for pressing the shape steel pile and a pressing member interlocked with a pressing cylinder for operating the pressing plate.

As another prior art, the "section steel pile extractor" (referred to as "Lee Han" prior art 2") of Registered Patent Publication No. 10-0992736 (registration date November 1, 2010) is a section steel pile drawer. A pressing member for pressing; A pressure cylinder for moving the pressure member back and forth; A pressure support plate on which the pressure cylinder is installed; An elevating cylinder for moving the pressure support plate up and down; And a lower plate disposed below the pressure support plate, wherein a through hole is formed in the pressure support plate, the body of the elevating cylinder is inserted and fixed in the through hole, and the piston rod of the elevating cylinder is fixed to the lower plate. It has been installed, and according to the elevating and lowering of the lifting cylinder, the pressure support plate has been disclosed to have a configuration in which the shape steel pile puller is moved up and down.

As can be seen in Figs. 1 and 2, the prior art 1 and 2 have a problem in that the pulling is not efficiently performed because the pressing member of the drawer is pulled out in a state in which both sides of the section steel pile are engaged with each other, so the engagement strength is limited.

That is, in the prior art 1 and 2, the pressing members on both sides of the drawer are pushed into the cylinder, and both sides of the shape steel pile are engaged with the pressing members.

Therefore, even in a state in which the pressing member is pushed with the cylinder to press both sides of the shape steel pile, the clamped engagement structure has a limited pressing critical point, resulting in a phenomenon in which the engaging portion slips during drawing.

In order to prevent such slipping, when the pressing member is pushed by increasing the pressing force of the cylinders on both sides, deformation occurs in which the wings of both sides of the H-shape are crushed inward. There is a problem in that the utility value of the section steel pile is deteriorated because it is impossible to sequentially insert and stack the earthing plates between the wings.
