The present invention relates to a pile joint device, and more particularly, by joining two piles used for foundation reinforcement of a civil engineering structure and the building by a non-welding method, a pile joint which can reinforce a structure and shorten a construction time. Relates to a device.

In general, in order to install a predetermined floor structure on top of the ground, the ground must have sufficient bearing capacity for the load of the floor structure. Soft ground is a ground that does not have sufficient bearing capacity in response to such ground conditions or load conditions of the flooring structure.

The soft ground should be prepared before the installation of the structural structure, and the countermeasures for stability and settlement of the structural material should be prepared before installation of the structural material. There is a piling method for charity construction.

The pile method refers to a method of constructing a concrete concrete pile or a steel pipe pile produced in a factory by hitting it with a diesel hammer or a hydraulic hammer, or by installing a drill after drilling a ground.

The type of pile used in the pile construction method is selected in consideration of the load condition applied to the structure, seismic design, and other impact stress.In the current construction site, high strength concrete piles are commonly used, and according to the Korean Industrial Standard (KS) In addition, the compressive strength of concrete manufactured by applying centrifugal force is defined as high-strength concrete pile (hereinafter referred to as “concrete pile”) by a pretension method of 78.5 N / mm 2 (800 kgf / cm 2) or more.

On the other hand, in civil engineering sites such as roads and bridges, load conditions are more complicated and diverse than buildings, and concrete piles often fail to satisfy design conditions. Instead, many steel pipe piles are used. It is prescribed in Korean Industrial Standard (KS).

In addition, the length of the pile can be selectively used depending on the depth of the support ground, but concrete piles and steel pipe piles are made as ready-made products in the factory, and concrete piles and steel pipe piles are 15m because it is difficult to transport products over a certain length. It is produced to the maximum length. However, in various construction sites, the pile length of more than 15m is often required depending on the ground conditions. For example, the signal complex in Busan, where Renault Samsung Motors Factory is located, has been constructed at about 60m.

As described above, when the length of the pile to be constructed exceeds a certain length, it is inevitable to connect two or more piles.

As a representative method of connecting two piles using a conventional pile joint device, in the case of concrete piles, the upper and lower piles are welded by welding the grooves formed in the steel joint plate integrally installed with the piles at one end of the pile. Construction method is used. And, in the case of the steel pipe pile, butt welding the upper and lower piles by using a welding groove formed in the end of the pile to face the pile and the pile.

By the way, the stress applied to the pile by the flooring structure has a characteristic that the maximum within about 10m from the ground surface. Therefore, if the depth to the supporting ground is so long that the length of the pile is to be increased, the lower part of the pile can provide sufficient strength even with a relatively weak concrete pile, while the upper part near the ground surface is sufficient by using a steel pipe pile. Make it possible to exercise the strength.

Conventionally, a welding joint method has been used to connect two piles as described above, and recently, in the case of a concrete pile, a non-welding joint method is used in addition to a welding joint.

Figure 1 is a side cross-sectional view showing a concrete pile connected by a non-welded joint method.

In addition, the connector 30 surrounds the outside of the front end bracket 10 and the head bracket 20, the inner side of the engaging groove for receiving the first locking jaw 15 and the second locking jaw (25) 32 is formed.

Meanwhile, in order to couple the front end bracket 10, the head bracket 20, and the connector 30 to the head side plate 24 and the connector 30, a fastening member 36 is coupled to the fastening member 36. ) Is formed.

However, the conventional non-welded joint has the following problems.

First, when foreign matter gets stuck between the tip bracket of the upper pile and the head bracket of the lower pile or when the end plate thickness of the bracket becomes thick, the connector cannot be closely attached to the head side plate of the head bracket, making it difficult to connect the fastening members such as bolts. .

Second, when the head end plate of the upper end of the upper pile and the head end of the lower pile becomes thinner, the tightening effect of the connector is lost, and the binding quality of the connector and the end plate is reduced, resulting in poor joint quality.

Third, the conventional pile joints can not be connected to the two steel pipe piles are subject to restrictions on use.

Here, one end of the first steel pipe pile may be mounted to the first recess formed in the upper side of the first side plate, the mounting may be made through a welding joint.

On the other hand, the first side plate and the first end plate form a state perpendicular to each other, can be integrally coupled by welding or manufactured by casting and forging. In addition, a first fastening hole for fastening the fastening member is formed in the first side plate along the circumferential direction. Here, the first reinforcing plate is coupled in contact with a portion of the inner surface of the first steel pipe and the inner surface of the first side plate and the upper surface of the first end plate.

Next, a second steel pipe pile and a second joint part for connecting with the first steel pipe pile are provided (S300).

Next, the second joint part consisting of a second side plate, a second end plate and the second reinforcement plate is mounted on the second steel pipe pile (S400). Here, one end side of the second steel pipe pile may be mounted to the second recessed portion formed on the lower side of the second side plate, the mounting may be made by welding. On the other hand, the second side plate and the second end plate form a state perpendicular to each other, can be integrally coupled through welding or manufactured by casting and forging. In addition, a second fastening hole for fastening the fastening member is formed in the second side plate along the circumferential direction. Here, the second reinforcing plate is coupled in contact with a portion of the inner surface of the second steel pipe and the inner surface of the second side plate and the upper surface of the second end plate.

Next, the first steel pipe pile and the second steel pipe pile in which the first joint portion and the second joint portion are mounted are close to each other (S600). Here, the guide protrusion and the guide hole formed on the surface facing each other in the first end plate and the second end plate are matched with each other to adjust the position of the first fastening hole and the second fastening hole for coupling the connecting plate.

Next, the connecting plate is contacted and coupled to the first joint part and the second joint part (S600). Herein, the protrusions protruding outwardly on the outer surfaces of the first end plate and the second end plate may be seated in the receiving portion formed on the inner surface of the connecting plate. Then, the center of the through-holes formed in the connecting plate to correspond to the first fastening hole and the second fastening hole to fasten the fastening member to the first fastening hole and the second fastening hole, and then insert the fastening member To combine.

Therefore, it is possible to reinforce the structure of the pile connected to each other through the pile joint device of the present invention, and also the steel pipe piles as well as steel pipe piles and concrete piles can be combined with each other more free construction.

Having described the preferred embodiments according to the present invention as described above, in addition to the embodiments described above, the fact that the present invention can be embodied in other specific forms without departing from the spirit or scope of the present invention is known to those skilled in the art It is obvious to those who have it.
