The second body portion 24 has a predetermined width and comes into contact with the outer periphery of the upper pile 10 .

The reason for configuring the second body portion 24 in a semi-circular arc shape is that the shape of the upper pile 10 is cylindrical. Therefore, it is natural that the shape of the second body part 24 varies according to the shape of the upper pile 10 .

One or more fixing handles 24a and 24b are installed to protrude from the outer surface of the second body 24, and the fixing handles 24a and 24b are installed to be spaced apart from each other.

In addition, the rotation handle 32 of the fastening part is rotatably installed on the outer surface of one side of the second body part 24 . For example, the rotation handle 32 may be rotatably installed on the base 30 formed on one side of the outer surface of the second body portion 24 via the first rotation shaft 34 .

The rotation handle 32 may be bent like an S (S) shape.

And, a second rotation shaft 38 in the form of a straight line is installed in the central portion of the rotation handle 32 penetratingly. Both side portions of the hook portion 36 penetrate and movably fit both sides of the second rotation shaft 38 exposed through the central portion of the rotation handle 32 , and the outer peripheral surface of both sides of the hook portion 36 . A length adjustment pattern 36a is formed there. For example, the length adjustment pattern 36a may be formed in the form of a thread having a predetermined length.

The hook portion 36 fitted to the second rotation shaft 38 may rotate in the same direction as the second rotation shaft 38 rotates.

The hook portion 36 may be formed as a ring in a diagonal shape.

In particular, both sides of the hook portion 36 penetrate through through holes (not shown) on both sides of the corresponding second rotation shaft 38 and are movable in the longitudinal direction, and by this movement, the locking groove 28a ) The length (L) of the hook portion 36 taken on can be varied. Although the through-holes on both sides of the above-described second rotation shaft 38 are not separately presented in the drawings, those skilled in the art will be able to fully understand the above-described description alone.

In addition, on both sides of the hook portion 36, the length of which is adjusted to some extent through the through hole of the second rotation shaft 38, with the second rotation shaft 38 interposed therebetween, the fixing members 40a and 40b (eg, inner Since the bolts (bolts threaded on the side) are respectively located, it is possible to maintain the length-adjusted current length (L) of the hook part (36). A case in which the length L of the hook part 36 is to be adjusted will be described with reference to FIG. 3 as an example. If you want to adjust the length (L) of the hook portion 36, first, the operator loosens the fixing members 40b on both sides of the hook portion 36 and moves to a portion without the length adjustment pattern 36a or an appropriate position. and release the fixing members 40a on both sides of the hook part 36 to release the coupling from both sides of the hook part 36 . Thereafter, the operator moves the hook portion 36 through the through hole of the second rotation shaft 38 in the longitudinal direction, and when the operator reaches the desired length L, the current length through the fixing members 40a and 40b. (L) is fixed. As a result, the length L of the hook portion 36 caught in the locking groove 28a may be adjusted by an operator's operation, and the adjusted length L may be fixed by the fixing members 40a and 40b.

In other words, the diameters of the upper pile 10 and the lower pile 12 used at the foundation construction site are various. If there is no length adjustment pattern 36a and the fixing members 40a and 40b, the length L of the hook portion 36 caught in the locking groove 28a is fixed to any one dimension. When the length (L) of the hook portion 36 is fixed to any one dimension in this way, the pile connection auxiliary device 20 according to the embodiment of the present invention is between the upper pile 10 and the lower pile 12 of the first diameter. It will only be used for connections.

By the way, if the length L of the hook portion 36 caught in the locking groove 28a can be varied through the length adjustment pattern 36a and the fixing members 40a and 40b, the upper pile 10 and the lower part of various diameters The file connection auxiliary device 20 according to an embodiment of the present invention may be applied to the connection between the files 12 . That is, for example, the pile connection auxiliary device 20 according to the embodiment of the present invention was used for the connection between the upper pile 10 and the lower pile 12 of the first diameter, and then the upper pile of the second diameter. It can be directly used for the connection between (10) and the lower pile (12). As such, in order to maximize the efficiency of use, the length adjustment pattern 36a and the fixing members 40a and 40b are required.

In the above description, the locking part 28 of the fastening part is installed on the outer side of one side of the first body part 22 , and other components of the fastening part except for the locking part 28 are installed outside the one side of the second body part 22 . Although it has been described as being installed on the side, the installation positions may be interchanged.

When the upper pile 10 is positioned at the upper part to be spaced apart by a predetermined distance with respect to the lower pile 12 installed in the vertical direction in the strata of the foundation construction site, the operator installs the pile connection auxiliary device 20 according to the embodiment of the present invention to the upper part Installed on the lower outer surface of the pile (10).

That is, the first body portion 22 and the second body portion 24 of the file connection auxiliary device 20 are placed on the lower outer surface (ie, the outer circumference) of the upper pile 10 in FIGS. 4 and 4 described above. As in 5, by rotating the rotation handle 32 in one direction (that is, the direction closer to the locking part 28), and hooking the hook part 36 to the locking groove 28a of the locking part 28, the rotation handle (32) is rotated in the other direction (that is, the direction away from the locking part 28) so that the first body part 22 and the second body part 24 are mutually fastened. Due to this, the pile connection auxiliary device 20 is fixed to the lower outer surface of the upper pile 12 .

Of course, the file connection auxiliary device 20 is loose, that is, the length (L) of the hook portion 36 caught in the locking groove 28a is adjusted to be too long, so the file connection auxiliary device 20 is the upper pile 12 of the It is not fixed to the lower outer surface, or the length L of the hook portion 36 caught in the locking groove 28a is too short so that the file connection auxiliary device 20 is not fixed to the lower outer surface of the upper pile 12 In this case, it is sufficient to readjust the length (L) of the hook portion 36 caught in the locking groove (28a). In other words, the operator moves both sides of the hook part 36 according to the diameter of the upper pile 12 through the through holes of both sides of the corresponding second rotation shaft 38 while being caught in the locking groove 28a. After optimizing the length (L) of the hook portion 36, the position can be fixed through the fixing members (40a, 40b).
