Concrete File Connecting Tool

The present invention relates to a concrete pile joint, and more specifically, in order to extend the length of the concrete pile constituting the wall when the construction of the wall wall, to combine the upper and lower concrete pile in the middle to connect the concrete pile up and down at the construction site It is about the concrete pile seam used to.

In general, the construction of the retaining wall is to prevent the earth wall or water pressure from collapsing when underground excavation, and to prevent accidents such as settlement of the surrounding buildings or ground, so as to be adjacent to the earth wall. It is placed around the ground and put into the ground.

By the way, concrete piles should be embedded with two or more piles in the case that the depth to be dug deep or the depth to be embedded according to the ground conditions or the ground is soft ground. For this purpose, in the past, a steel seat plate was installed at the end of the concrete pile and welded.

However, this method of jointing by welding requires the seat of steel to be joined to the end of the concrete pile in advance, and many types such as upper, middle and lower connecting concrete piles and general concrete piles depending on the presence and position of the seat plate. Files must be prepared and loaded. Therefore, many of these types of concrete piles require a storage space at the pile production site, require a separate part, and there is a problem that the cost increases accordingly. In addition, since the welding must be performed at the construction site, it takes a lot of time in the joint and the environment around the construction site is poor, so there is a problem in not expecting a perfect joint.

In order to solve the problem of the welding joint method, the joint as shown in FIG. 2 has been developed Patent No. 10-0835778 (removable joint device of the concrete pile). The joint 110 is disposed between the upper and lower concrete piles 101 and 102, as shown, the upper disc 141 is fixed to the upper concrete pile 101 by the upper bolt 115, the lower disc 142 The lower bolt 116 is fixed to the lower concrete pile 102 to connect the upper and lower concrete piles 101 and 102 in the middle.

To this end, the upper through-hole 111a is disposed in the circumferential direction through the upper disc 141, and the lower through-hole 112a is disposed in the circumferential direction through the lower disc 142, so that upper and lower bolts 115 and 116 are provided. The upper and lower through holes 111a and 112a pass through the upper nuts 101a and the lower nuts, respectively.

At this time, for example, the concrete pile 101, as shown in Figure 2, after being constructed as a retaining wall, a plurality of fastening holes (H) in the longitudinal direction through the circumferential surface so that the belt or the like can be installed on the wall Is formed, the fastening hole (H) is coupled to the support bar (S) for supporting the strip length (W) in the appropriate position.

By the way, the general concrete pile 101 is manufactured in advance through a centrifugal molding process, the alignment of the fastening hole (H) may be disturbed due to the molding error, thereby misalignment of the fastening hole (H) when constructing the retaining wall Due to the position of the support rod (S) is not correct, accordingly there is a problem that can not be installed or poor installation of the belt (W).

That is, when the fastening hole H, etc., formed on the outer circumferential surface of the upper concrete pile 101 due to processing tolerances are manufactured to have different angles in the circumferential direction with the fastening hole of the lower concrete pile 102, support rods of upper and lower concretes (S) When the upper concrete pile 101 is rotated to align the up and down directions, since all the upper nuts are misaligned with respect to the upper through hole 111a, the upper bolt 115 is connected to the upper nut through the upper through hole 111a. There is a problem that can not be concluded.

In addition, when the concrete pile is formed, the upper and lower nuts have a circumferential deviation in the circumferential direction due to another processing tolerance, so that when the upper concrete pile 101 is to be rotated in the circumferential direction when engaging the joint device, the upper and lower through holes ( Since the upper and lower through holes 111a and 112a are formed in the circular holes as shown in FIG. 1, the upper and lower through holes 111a and 112a can be inserted in the arrangement as shown in FIG. If the deviation cannot be accommodated at all, and thus, for example, one of the through holes 111a and 112a is arranged at different intervals in the circumferential direction, the upper bolt 115 is fastened to the upper nut through the upper through hole 111a. There is a problem that the concrete pile 101 with the arrangement deviation cannot be used or cannot be used.

It is fastened to 42. To this end, a plurality of upper nuts 42 are disposed in the circumferential direction through the PC bolt 1b on the bottom surface of the upper concrete pile 1, and the upper bolts 41 correspond to the plurality of upper nuts 42. The dog penetrates the upper plate portion 21 through the upper through hole 24 and is fastened to each of the upper nuts 42.

At this time, the upper nut 42 may have a slight arrangement deviation in the circumferential direction when manufacturing the upper concrete pile 1, as shown in A in FIG. In this case, if the upper through hole 24 is circularly disposed in the correct position, the upper nut 41 is disposed through the upper through hole 24 by the upper bolt 41 due to the arrangement deviation A of the upper nut 42. Can not be tightened. However, since the joint 10 of the present invention takes the form of a slot extending in the circumferential direction of the upper plate portion 21 as shown in FIG. 8, at least one upper through hole 24 of the connection ring 20. In addition, as shown in FIG. 9, the upper bolt 42 may be fastened by accommodating the arrangement deviation A through the upper through hole 24 as shown in FIG. 9.

Likewise, the lower plate fastening means 50 is the number of coupling the lower plate portion 22 to the lower concrete pile (2):

 However, even if one upper nut 42 of the upper concrete pile 1 is misaligned by an angle A, for example, as shown in FIG. 3, the upper through hole 24 is formed in the circumferentially extending slot. Since it has a shape, as shown in FIG. 9, the arrangement deviation A is accommodated by the upper through hole 24, and the upper bolt 41 is fastened to the upper nut 42 through the upper through hole 24. The coupling ring 20 and the upper concrete pile (1) can be combined.

In addition, as shown in FIG. 10, although all the upper nuts 42 are normally arranged, even when the supporting rod S coupled to the outer peripheral surface of the upper concrete pile 1 is misaligned by the arrangement deviation B, the upper through hole Since the 24 extends in the form of a slot, the supporting rod S of the abnormally arranged upper concrete pile 1 is rotated by rotating the upper concrete pile 1 in the direction of the arrow P by the placement deviation B. As shown on the right side of FIG. 10, the upper rod 41 may be aligned with the supporting rods of the lower concrete pile 2 normally arranged axially, that is, vertically, and in this state, through the upper through hole 24. By coupling to the upper nut 42 it is possible to combine the connection ring 20 and the upper concrete pile (1).

On the other hand, according to another embodiment of the present invention, since the fitting hole 10 also has a lower through-hole 26 of the connecting ring 20 in the form of a slot, as shown in Figure 11, the arrangement deviation (C) is upper When the upper concrete pile 1 is rotated by the angle C in the direction of the arrow Q in order to align the support bar S, that is out of an acceptable range by the through hole 24, the upper nut ( When the position of 42 is beyond the right end of the upper through hole 24, the lower bolt 51 is released and pulled out of the lower nut 52 to separate the connecting ring 20 from the lower concrete pile 2, As shown in FIG. 12, the connecting ring 20 is turned in the direction of the arrow R with respect to the lower concrete pile 2. At this time, the connection ring 20 can be rotated only to the extent that the lower through hole 26 can maintain alignment with the lower nut 52. Accordingly, the connecting ring 20 is further rotated by the angle D as shown in the third drawing of FIG. 12 to be recombined to the lower concrete pile 2, and the upper through hole 24 as shown in the fourth drawing. ) Can be aligned with the upper nut 42, the coupling ring 20 can be combined with the upper concrete pile (1).
