And, in order to stably install a deck rod or fence on the ground, the method of building a concrete foundation in the ground and fixing the pillars of the deck rod or fence on it is mainly used.

However, since the conventional concrete foundation must be tailored to the ground characteristics of the site, it is mainly custom-built on site. In addition, the formwork must be cut and made manually on site, and the formwork must be dismantled after curing of the concrete, which requires many installations. It has the disadvantage of requiring time and manpower, delaying the construction period, and increasing construction costs.

In addition, since it is difficult to accurately make the form to a certain size on site, the constructability of the concrete foundation is poor, and it is difficult to obtain uniform quality.

As such, the concrete foundation that holds the pillars of the deck rod or fence has many difficulties in construction, so there is a need for a foundation structure that can construct the pillar foundation more simply, stably, and economically. am.

Hereinafter, the present invention will be described in detail with reference to the attached drawings.

1 to 3 are perspective views showing a fence basic pile according to an embodiment of the present invention, and Figure 4 is a cross-sectional view showing a fence basic pile according to an embodiment of the present invention.

As shown in Figures 1 to 4, the fence foundation pile is buried in the ground and serves to support the pillars of the fence, and is a foundation structure with excellent constructability, such as being able to replace an existing concrete foundation.

For this purpose, the fence foundation pile includes a base plate 12 as a means of holding the pillars of the fence while in contact with the ground.

The base plate 12 is in the form of a square plate made of metal. This base plate 12 has a plurality of fastening holes 10 for fastening bolts to connect to the pillar side, for example, a plate. Four fastening holes 10 located at each of the four corners are formed, and a tube-shaped connection part 11 extending vertically downward for a certain length is formed integrally in the center.

Accordingly, the pillars of the fence are fastened together with fastening holes 10 in the base plate 12 and bolts and nuts, for example, stud bolts 18 and nuts 19, which are fastened to the bolt holes in the pillar plate of the pillar. As a result, it is possible to maintain a stable installation state while being fixed to the foundation pile side, and the upper end of the vertical pipe 13 is inserted into the connection part 11 of the base plate 12, allowing it to be coupled in a press-fit structure.

In particular, a convex curved portion 14 is formed around the inner circumference of the connecting portion 11, for example, the inner circumference of the boundary portion extending from the base plate 11 to the connecting portion 11, and the convex curved portion 14 thus formed is formed. ), the concave curved portion 15 formed with the same curvature around the outer edge of the upper end of the vertical pipe 13 can be closely adhered and fitted.

In addition, stud bolts 18 extending vertically upward are integrally installed in each fastening hole 10 of the base plate 12, and nuts 19 are fastened to these stud bolts 18. It becomes possible.

For example, with the foundation pile buried in the ground, insert the bolt hole of the column plate at the bottom of the fence column into the stud bolt (18) installed on the base plate (12) of the foundation pile, and then insert the stud bolt from the top. By fastening the nut (19) to (18), the fence pillar can be fixed to the foundation pile.

By connecting and installing the pillars using the stud bolts 18 already installed on the base plate 12, bolt and nut fastening work can be performed quickly and easily.

That is, conventionally, in order to connect the pillar side with a certain foundation pile buried in the ground, a bolt is inserted into a narrow gap at the bottom (for example, a narrow gap between the ground and the top of the foundation pile) and the bolt is inserted into the hole of the top plate. , while holding the bolt, fasten the nut to the bolt protruding from the top, or insert the bolt into the hole in the top plate from above and insert the nut into the narrow gap at the bottom while holding the bolt to fasten the nut to the bolt. There are disadvantages in terms of workability, such as being very inconvenient and taking a lot of time.

In addition, conventionally, a certain distance must be maintained between the ground and the top of the foundation pile to secure space for fastening by inserting bolts or nuts, and because of this, the foundation pile cannot be completely buried in the ground and must be placed above the ground. There are disadvantages to the stability of the basic file, such as having to install it with a certain portion spaced apart.

In this regard, in the present invention, the stud bolts 18 are integrally provided on the base plate 12 of the foundation pile, so that when connected to the column side, the nut 19 is attached to the stud bolt 18 protruding upward. By simply fastening, you can easily connect the foundation pile and the column, making it very easy to fasten the bolts and nuts for the connection between the foundation pile and the column.

In addition, since the bolt and nut fastening work is performed from above, the foundation structure can be installed with the base plate 12 in as close contact with the ground as possible, ultimately ensuring the sturdiness and stability of the foundation pile buried in the ground. There will be.

In a preferred embodiment, a pin hole 16 penetrating the thickness of the plate is formed on one side of the base plate 12, and the pin hole 16 formed in this way serves as a reference when driving the foundation pile into the ground. The guide pin 17 can be inserted.

For example, when constructing a foundation pile, if the guide pin 17 is inserted into the pin hole 16 and the foundation pile is struck and driven into the ground while being driven into the ground at a certain depth, the foundation pile at this time may tilt sideways or Instead, it can be embedded straight in the correct position and in an accurate vertical position while being guided by the guide pin 17.

In addition, the fence foundation pile is completely buried in the ground and includes a vertical pipe 13 as a means of exerting a strong bearing force.

The vertical pipe 13 is in the form of a circular tube, and is fitted and coupled to the connection part 11 extending vertically downward from the center of the bottom of the base plate 12 using the upper end.

In addition, a concave curved portion 15 is formed around the outer edge of the upper end of the vertical pipe 13, and accordingly, the upper end of the vertical pipe 13 forms a shape in which the entire circumference is spread outward, for example, a morning glory shape. .

This vertical pipe 13 has the characteristic of being integrally coupled to the base plate 12 through a press-fit structure instead of a welding method or bolt fastening method.

For this purpose, the upper end of the vertical pipe 13 is coaxially inserted into the inside of the connection part 11 of the base plate 12 and press-fitted, and the joining part at this time is a convex shape formed around the inner circumference of the connection part 11. The curved portion 14 and the concave curved portion 15 formed around the outer upper end of the vertical pipe 13 are joined together to form a structure in which they are pressed, and thus the convex curved portion 14 and the concave curved portion 15 ) The base plate 12 and the vertical pipe 13 can be integrally coupled by the press-fitting structure between them.

Here, the press-fitting structure between the convex-shaped curved portion 14 and the concave-shaped curved portion 15 can be formed using a hydraulic presser (not shown).

For example, the upper end of the vertical pipe 13 is first retracted (as if in the shape of an embedded guide), and then the connection part 11 of the base plate 12 and the upper end of the vertical pipe 13 are temporarily joined. When the hydraulic indenter is set in this state and the hydraulic indenter is operated, the joining portion at this time is formed into the convex curved portion 14 and the concave curved portion 15, and at the same time, they can be joined by pressing each other.

At this time, the end of the upper end of the vertical pipe 13, that is, the end of the upper end where the concave curved portion 15 is formed, can be maintained at the same height as the upper surface of the base plate 12.

And, in a state where the vertical pipe 13 and the base plate 12 are coupled by a press-fit structure, the upper part of the vertical pipe 13 with the concave curved portion 15 is the convex curved surface of the connecting portion 11. By being bound in a structure that surrounds and covers the part 14, the vertical pipe 13 can secure a locking structure in the axial direction, and the coupling relationship between the base plate 12 and the vertical pipe 13 is further improved. can be maintained closely.

In a preferred embodiment, a burial guide portion 20 is formed around the lower end of the vertical pipe 13 in the form of a concave shape toward the center, so that the vertical pipe 13 can more easily dig into the ground when buried. This makes it possible to bury the foundation pile more easily.

Figures 5 to 7 are front views showing a state in which fence foundation piles are installed according to an embodiment of the present invention.

As shown in Figures 5 to 7, the lower end of the vertical pipe 13 of the foundation pile 100 is positioned and vertically positioned against the ground, and in addition, the bottom end of the vertical pipe 13 of the foundation pile 100 is placed in the pin hole 16 in the base plate 12. At the same time as inserting the guide pin (17), drive the guide pin (17) into the ground.

Subsequently, when the electric hammer 140 is pressed against the base plate 12 of the foundation pile 100 and the electric hammer 140 is operated, the foundation pile is struck by repeated blows of the electric hammer 140. The vertical pipe (13) of (100) penetrates the ground and is dug into the ground.

At this time, the foundation pile 100 is driven in while being supported by the guide pin 17, so that it can be buried in an accurate vertical position.

Subsequently, if the foundation pile 100 is driven into the ground by striking the base plate 12 of the foundation pile 100 until it is in close contact with the ground, the installation work of the foundation pile 100 is completed.

When the pillars 120 of the fence 110 are connected to the foundation pile 100 installed in the ground in this way through a fastening structure, the pillars 120 of the fence 110 are connected to the foundation pile 100 based on the foundation pile 100. You can install it.

Figure 8 is a front view showing the construction state of a fence using fence basic piles according to an embodiment of the present invention.

As shown in FIG. 8, the fence 110 is constructed in a structure built on the basis of foundation piles 100 embedded in the ground.

For this purpose, after burying the foundation pile 100 in the ground, a bolt hole (not shown) formed in the pillar plate 130 of the pillar 120 is connected to the stud bolt 18 of the base plate 12 exposed on the ground. ), for example, by inserting the bolt hole corresponding one-to-one with the fastening hole 10 in the base plate 12 to erect the pillar 120, and then fastening the nut 19 to the stud bolt 18 from above, , the pillar plate 130 can be coupled to the base plate 12, and ultimately the pillar 120 can be firmly erected on the foundation pile 100, and at the same time, the pillar 120 at this time can be used to construct the fence 110. ) can be constructed.

In this way, by using the foundation pile 100 buried in the ground instead of the existing concrete foundation to hold the pillar 120 of the fence 110, the overall constructability of the fence, including installation of the fence foundation and fence pillar, is improved. can be improved.

Figure 9 is a front view showing a state in which a fence foundation pile is installed using a guide pin according to an embodiment of the present invention.

As shown in FIG. 9, here, the fence foundation piles are installed at regular intervals (pitch) and in an accurate vertical position using the guide pins 17.

For this purpose, guide pins 17 are installed at regular intervals on the ground at a location corresponding to the installation location of the fence foundation pile, and the fence foundation pile is installed from one side using the guide pins 17 arranged at regular intervals. If you install them one by one, you can install the fence foundation piles at precise intervals.

For example, the vertical pipe 13 and the base plate 12 are erected next to the guide pin 17 by inserting the pin hole 16 in the base plate 12 into the guide pin 17 embedded in the ground. Next, when the upper end of the base plate 12 is struck and driven into the ground, the vertical pipe 13 and the base plate 12, that is, the foundation pile, are guided by the guide pin 17 without tilting to the side. It can be embedded in the ground in an accurate vertical position.

As such, in the present invention, when installing a pillar for constructing a fence, a combination of a base plate and a vertical pipe can be maintained in a solid and stable buried state in the ground, and the base plate and the vertical pipe have a welded or fastened structure. By providing a new fence foundation pile combined with a press-fit structure rather than a press-fit structure, construction is easy, construction costs can be reduced, and the construction period can be shortened, while improving the manufacturability of the foundation pile and securing sufficient strength and durability. It is possible to maintain the stability of the fence and at the same time improve the construction quality of the fence.
