  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1> Overall Configuration The wooden pile connector 1 of the present invention is for connecting two wooden piles 2a and 2b to form a single support pile. (Figure 1)
The wooden pile connector 1 of the present invention includes a horizontal plate 11, an upper vertical plate 12 erected on the upper surface 111 of the horizontal plate 11, and a lower vertical plate 13 erected on the lower surface 112 of the horizontal plate 11. (Figure 1)
Hereinafter, each component will be described in detail.

<2> Horizontal plate The horizontal plate 11 is a disk having substantially the same diameter as the wooden pile 2 to be connected.
When the horizontal plate 11 connects the wooden piles 2, the upper surface 111 and the lower surface 112 abut against the upper wooden pile 2a and the lower wooden pile 2b, respectively.
On the upper surface 111 of the horizontal plate 11, an upper vertical plate 12 is erected vertically to the horizontal plate 11.
Similarly, a lower vertical plate 13 is erected vertically on the lower surface 112 of the horizontal plate 11 with respect to the horizontal plate 11.

<3> Vertical Plate The upper vertical plate 12 and the lower vertical plate 13 are rectangular flat plates whose bottoms are approximately the same as the diameter of the horizontal plate 11.
The upper vertical plate 12 and the lower vertical plate 13 are erected at the center of the horizontal plate 11.
The upper vertical plate 12 and the lower vertical plate 13 are formed to be on the same plane.
The upper vertical plate 12 and the lower vertical plate 13 are inserted into slits or grooves 21 formed in the wooden pile 2. The height of the upper vertical plate 12 and the lower vertical plate 13 is approximately the same as the depth of the slit 21.

<4> Connection with wooden pile The wooden pile connector 1 inserts the upper vertical board 12 and the lower vertical board 13 in the slits 21a and 21b of the wooden piles 2a and 2b arrange | positioned up and down. Thereby, the wooden piles 2a and 2b are connected via the wooden pile connector 1.

<5> Placing a wooden pile Next, a method for placing a wooden pile will be described.
First, the wooden pile 2b positioned below is driven by press-fitting or rotational press-fitting to a predetermined depth, and the lower vertical plate 13 of the pile connector 1 is fitted and fixed to the slit 21b. (Fig. 2a)
Then, the upper vertical plate 12 of the pile connector 1 is fitted into the slit 21b of the pile 2a suspended from a pile driving machine (not shown). (Fig. 2b)
The wooden piles 2 a and 2 b are connected via the wooden pile connector 1.

While applying pressure to the upper wooden pile 2a, the wooden piles 2a and 2b are placed on the ground. (Fig. 2c)
Since the wooden piles 2 a and 2 b are connected via the pile connector 1, the pressure applied to the wooden pile 2 a is transmitted to the lower wooden pile 2 b via the pile connector 1.
In addition, when a rotational force is applied to the wooden pile 2a, the applied rotational force is transmitted to the wooden pile 2b via the upper vertical plate 12, the horizontal plate 11, and the lower vertical plate 13.
For this reason, it is possible to cope with not only press-fitting but also driving by rotary press-fitting.

The upper wooden pile 2a and the lower wooden pile 2b insert the upper and lower vertical plates 12 and 13 of the pile connector 1 into the slits 21a and 21b of the wooden piles, respectively.
By comprising in this way, since the horizontal force concerning one wooden pile is transmitted also to the other wooden pile via the pile connector 1, the support pile which has bending strength can be constructed | assembled.

Other examples

<6> Fixing of wooden pile connector In the above-described embodiment, the wooden pile connector 1 has the upper vertical plate 12 and the lower vertical plate 13 inserted in the slits 21a and 21b of the wooden piles 2a and 2b arranged above and below. However, the bolt hole 22 was formed in the wooden pile 2 so as to pass through and substantially perpendicular to the center of the slit 21, and fitted into the slit 21 in the approximate center of the upper vertical plate 12 and the lower vertical plate 13. The bolt hole 14 is formed so as to be continuous with the bolt hole 22 when inserted, and the bolt 3 is inserted into the bolt holes 14 and 22 with the upper vertical plate 12 and the lower vertical plate 13 being inserted into the slit 21. A nut 4 may be screwed onto the inserted bolt 3 to fix the pile connector 1 and the wooden pile 2.

The upper wooden pile 2a and the lower wooden pile 2b are integrated with each other via a pile connector 1 that is fixedly connected to the wooden pile.
For this reason, when the upper wooden pile 2a is pulled upward, the lower wooden pile 2b is also lifted upward. Therefore, it is possible to construct a support pile that can be pulled out as well as driven.

<7> Arrangement of Upper Vertical Plate and Lower Vertical Plate In the embodiment described above, the upper vertical plate 12 and the lower vertical plate 13 are formed to be on the same plane, but are formed so as to intersect each other and form a right angle. May be. (Figure 3)
By making the upper vertical plate 12 and the lower vertical plate 13 orthogonal, it is possible to construct an isotropic support pile having a constant bending strength even when the direction in which the horizontal force acts is rotated.

<8> Cylinder In addition, the pile connector 1 may be provided with a cylinder 15 along the outer periphery of the horizontal plate 11 so as to surround the ends of the wooden piles 2a and 2b. (Fig. 4)
The cylinder 15 may be fixed to the horizontal plate in advance before the connection of the wooden piles 2a and 2b, or is inserted into the wooden pile 2a after the wooden piles 2a and 2b are connected and arranged on the outer periphery of the horizontal plate 11. And may be fixed.
The cylindrical body 15 serves as a guide when connecting the wooden piles 2 a and 2 b, and the horizontal force and rotational force acting on the vertical plates 12 and 13 are distributed to the cylindrical body 15 by the cylindrical body 15.
Further, the cylindrical body 15 may be provided with a bolt hole 151 continuous with the bolt hole 22 of the wooden pile 2. Thereby, the force acting on the bolt hole 22 is dispersed in the cylinder 15. In this case, if the height of the cylindrical body 15 is higher than the vertical plates 12 and 13, the bolt holes 14 of the vertical plates 12 and 13 are unnecessary, and the bolt holes 22 of the wooden pile 2 do not need to penetrate the slit 21. .
