Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates generally to wooden pile structures. More specifically, the present invention relates to a wooden pile structure capable of coping with subsidence of small buildings at low cost.

[0002]

2. Description of the Related Art When building a building on a soft ground, consideration must be given so that the building will not be damaged by ground subsidence. When the building is a large-scale building such as a building, the ground is improved, or support piles are used to drive the pile tips to the support layer, and complete measures are taken against ground subsidence.

[0003]

However, in the case where the building is a small building such as a general house, if the same measures as those for a large building are taken, the building cost will be considerably high. The present invention has been devised in consideration of such a current situation, and an object of the present invention is to provide a wooden pile structure that prevents ground subsidence of a small building at a low cost.

[0004]

A wooden pile structure for preventing ground subsidence of a small building according to claim 1 is a plurality of first vertical piles located directly below a concrete foundation and a concrete foundation. Multiple second positions located at a predetermined horizontal distance from the edge away from the concrete foundation
The vertical pile and the horizontal member for connecting the first vertical pile and the second vertical pile to each other are provided.

The wooden pile structure according to claim 2 of the present application is the structure of claim 1, wherein the head is located at the intersection of lines extending from each of the second vertical piles in a direction parallel to the edge of the concrete foundation. It further comprises a plurality of third vertical stakes in which the parts are located, the third vertical stake and the second vertical stake being connected to each other by a horizontal member.

The wooden pile structure according to claim 3 of the present application is characterized in that, in the structure of claim 1 or 2, adjacent vertical piles are connected by diagonal members.

According to a fourth aspect of the present invention, in the wooden pile structure according to any one of the first to third aspects, all or some of the vertical piles and the horizontal members are formed of logs. It is characterized by that.

BEST MODE FOR CARRYING OUT THE INVENTION Next, a wooden pile structure according to a preferred embodiment of the present invention will be described with reference to the drawings. 1 is a plan view of a wooden pile structure according to a first embodiment of the present invention, FIG. 2 is a view as seen from line 2-2 of FIG. 1, and FIG. 3 is line 3 of FIG. It is the figure seen from -3. In FIG. 1, the broken line indicates the concrete foundation of the building. 2 and 3, for simplification of the drawings,
The concrete foundation is omitted.

A wooden pile structure according to a first embodiment of the present invention, generally designated by the reference numeral 10 in FIG. 1, is a first vertical pile 1 which is located directly below a concrete foundation.
2 and a second vertical pile 14 located at a position separated from the edge of the concrete foundation by a predetermined horizontal distance d in the direction away from the concrete foundation.

In the wooden pile structure 10 shown in FIG. 1, each of the first vertical piles 12 and the second vertical piles 14 is four. The first and second vertical stakes 12, 14 are wooden stakes, preferably made of logs. Further, waste materials may be used as the vertical piles 12 and 14.

The first and second vertical piles 12, 14 include:
As shown in FIGS. 2 and 3, recesses 12a and 14a are provided at appropriate locations in the length direction.
The recesses 12a and 14a are preferably provided at a plurality of positions facing each other at predetermined intervals in the length direction.

The wooden pile structure 10 has recesses 12a and 14a.
The horizontal member 16 is fitted in. In the illustrated embodiment, the horizontal member 16 is made of a log material, but a square material may be used. Recesses 12a, 14
The horizontal member 16 fitted in a is firmly fixed to the vertical piles 12 and 14 by bolts 17. In addition,
Instead of the bolt 17, other fixing means such as a wire or a screech may be used.

In FIG. 2 and FIG. 3, the horizontal member 16 is arranged only in the uppermost recesses 12a, 14a of the vertical piles 12, 14, but in the situation of the ground where the wooden pile structure 10 is installed, etc. Accordingly, the recesses 12a and 14a other than the uppermost recesses 12a and 14a can be arranged.

Further, as shown in FIG. 4, adjacent vertical piles 12 and 14 may be connected by diagonal members, that is, braces 18.

FIG. 5 is a view showing a wooden pile structure 20 according to the second embodiment of the present invention. Wooden pile structure 20
Is different from the wooden pile structure 10 in that the third vertical pile is provided. That is, the wooden pile structure 20
Is the first vertical pile 2 located just below the concrete foundation
2, a second vertical pile 24, a first vertical pile 22 and a second vertical pile 24, which are located at a predetermined horizontal distance d away from the edge of the concrete foundation and away from the concrete foundation. And a horizontal member 26 that connects the heads to each other, and the head is located at the intersection of the lines (XX, YY) extending from each of the second vertical piles 24 in a direction parallel to the edge of the concrete foundation. Is provided, and the third vertical pile 28 and the second vertical pile 24 are connected by the horizontal member 30. The first, second and third vertical piles 22, 24 and 28 are also provided with recesses (not shown) into which the horizontal members are fitted, like the vertical piles 12 and 14.

Wooden pile structure 1 constructed as described above
Nos. 0 and 20 increase the resistance area to the ground due to the presence of the horizontal members 16, 26 and 30 extending from the vertical piles 12, 14, 22, 24 and 28 in the horizontal direction. Can be dealt with.

The present invention is not limited to the above-described embodiments of the invention, and various modifications can be made within the scope of the invention described in the claims, and these are also within the scope of the invention. Needless to say, it is included in.

For example, although a single member is used for the vertical pile in the above-mentioned embodiment, as shown in FIG. 6, depending on the situation of the ground where the wooden pile structure is installed, etc. You may use what connected two members by fixing means, such as a bolt, as a vertical pile.

[0019]

According to the present invention, there is provided a wooden pile structure capable of coping with ground subsidence at a low cost.
By using waste materials as materials for the vertical piles and horizontal members, the construction cost can be further reduced and the waste materials can be reused.
