FIG. 5 is a cross- Of FIG.

1 to 5, a pile according to an embodiment of the present invention includes a pile body 100, a pile support 200, and a pile head 300.

The pile body 100 has a cylindrical shape and a conical shape having a sharp bottom end in succession. That is, it forms a general pile which is easy to insert on the ground. The pile body 100 shown in FIG. 1 has a cylindrical shape and a continuous conical shape. However, if necessary, the body may be formed of a polygon such as a triangle, a square, and the lower end may be formed into a polygonal shape such as a triangular pyramid or a quadrangular pyramid.

The pile body 100 has a hollow shape and an open top shape for fastening the pile support 200 and the pile head 300 to each other.

The pile support 200 is for fixing the pile body 100 to the ground and is formed in a plate shape extending in the vertical direction of the pile body 100 and is fastened to the side surface of the pile body 100. Specifically, the pile support 200 has a first end 210 hinged to the side of the pile body 100 by a hinge shaft 20 and a second end 220 hinged to the lower side along the outer side of the pile body 100 . The other end 220 of the pillar body 100 may extend upwardly along the outer surface of the pillar body 100. In this case, So that the pile support 200 is pivoted laterally from the upper side.

The pile support 200 is formed with a pivot protrusion 230 protruding from the first end 210 to the inside of the pile body 100. The turning operation of the turning projection 230 functions to turn the other end 220 laterally from the lower side by the hinge shaft 20 to which the one end 210 is fixed.

Meanwhile, in one embodiment of the present invention, the pile support 200 is formed on both left and right sides of the pile body 100 to form a pair of structures. However, four pile supports 200 are also provided on both front and rear sides It is also possible. That is, the number of the pile supports 200 may be varied as needed.

The pile head 300 is for operating the pile support 200. The pile head 300 is coupled to the pile body 100 so as to be vertically movable from the inside of the pile body 100, The other end 220 of the pile support 200 is pivoted sideways from below.

Also, the pile head 300 is formed in a planar shape of a polygonal shape with a square top or a hexagonal shape in order to facilitate price with a hammer or the like, and a rope hole 320 for fastening the rope is formed on the side of the upper end.

In addition, since the pile head 300 is hollow, the production cost can be reduced.

As described above, the pile according to an embodiment of the present invention has a structure in which the pile support 200 is fastened to the side and the pile head 300 is fastened to the upper end based on the pile body 100. In the following, this fastening structure will be described in more detail.

The pile support 200 is formed in a plate shape along the shape of the outer surface of the pile body and the outer surface of the pile body 100 is provided with a receiving groove 110 in which the pile support 200 is received. Thus, when the pile support 200 is in close contact with the receiving grooves 110 of the pile body 100, the pile support 200 is used on the outer surface of the pile body 100, In one embodiment, the pile according to an embodiment of the present invention has a flat and smooth surface. That is, as in the case of a general pile, the side of the pile forms a smooth straight line without bending in the up and down direction, thereby facilitating insertion into the ground.

In this case, the pile support 200 is formed in a plate shape. When the pile body 100 has a cylindrical shape, the pile support 200 is formed as a curved plate. When the pile body 100 has a rectangular tube shape, the pile support 200 is formed as a flat plate. By gradually reducing the thickness of the other end 220 of the pile support 200 and decreasing the depth of the receiving groove 110 gradually toward the lower side, the step of the contact surface at the lower end is minimized to form a smooth close contact structure .

The lower end 310 of the pile head 300 according to an embodiment of the present invention has a curved surface gradually narrowing in width from the outer periphery to the center and the pivot protrusion 230 of the pile support 200 has an end It forms a curved surface and is slanted upward by about 45 °. Accordingly, when the pile head 300 moves downward, the end of the pivotal projection 230 of the pile support 200 contacts the outer edge of the lower end 310 of the pile head 300 and slides downward along the curved surface, As shown in FIG. As described above, since the turning projection 230 is rotated by the sliding operation along the curved surface with respect to the external pressure, the friction and damage can be minimized, and a more smooth turning operation can be performed. The lower end portion 310 of the pile head 300 is connected to the lower surface of the rotation protrusion 230 so that the lower end portion 310 of the pile head 300 can be linearly rotated. A fixing force for fixing the rotated state can be sufficiently provided.

Also, in one embodiment of the present invention, the pile body 100 and the pile head 300 can be threaded and screwed, respectively. Thus, the pile head 300 can be smoothly moved up and down, and a pressing force for rotating the pivoting projection 230 can be sufficiently generated. In addition, the degree of pressurization can be easily adjusted by adjusting the degree of screw rotation, and the pile head 300 can be moved up and down.

6 to 9 are views for explaining operation characteristics of a pile according to an embodiment of the present invention. 6 is a view illustrating a state in which a pile is inserted into the ground according to an embodiment of the present invention, and FIG. 7 is a view illustrating a state in which the pile head moves downward and is fixed in the pile according to an embodiment of the present invention. FIG. 8 is a view showing a state in which the pile head is moved upward to release the supporting force of the pile support according to the embodiment of the present invention. FIG. 9 is a perspective view of a pile according to an embodiment of the present invention, Fig.

6 to 9, the operation characteristics of the pile according to an embodiment of the present invention will be described.

6, when the pile support 200 is in close contact with the receiving groove 110 of the pile body 100, the lower end of the pile body 100 is directed to the ground, and the pile head 300 The upper surface of the pile body 100 is inserted into the ground by a hammer or the like. At this time, not only the pile body 100 but also the pile support 200 are inserted into the ground.

7, when the pile head 300 is inserted into the pile body 100 by screw rotation of the pile head 300 in a state where the pile body 100 and the pile support 200 are inserted into the ground, To move downward. The end of the rotation protrusion 230 of the pile support 200 is brought into contact with the outer edge of the lower end 310 of the pile head 300 and slides downward along the curved surface to be pivoted about the center of the lower end 310 of the pile head 300 . That is, the pivot projection 230 is rotated from above to below.

The other end 220 of the pile support 200 is pivoted about the hinge shaft 20 as the pivot protrusion 230 is rotated so that the pile support 200 is supported laterally And the lower end portion 310 of the pile head 300 continuously keeps the pivot protrusion 230 pressed, so that the pile body 100 is supported to be fixed in the ground.

As a result, it is possible to prevent the pile body 100 from being dislocated, deformed in position and angle.

Next, as shown in FIG. 8, the pile head 300 is screw-rotated in the opposite direction to move upward in the pile body 100 in the process of pulling the pile out of the pile. Accordingly, since the lower end 310 of the pile head 300 is separated from the pivot protrusion 230, the supporting force of the pile support 200 against the lateral pivoting state is released.

9, when an external force pulling the pile head 300 upward is applied, a load of earth or the like acts on the pile support 200 as a repulsive force, And the pile body 100 is pulled out to the outside while the other end 210 is rotated downward.

As described above, the pile according to an embodiment of the present invention can be firmly fixed after being inserted into the ground, and is easy to insert, and can have a sufficient supporting force against a ground surface of a soft material. There is one advantage.
