Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woodworking bed that is used, for example, placed on the bottom of a river to prevent excavation of the riverbed and shore to protect the seawall and at the same time serve as a habitat for fish and shellfish.

[0002]

2. Description of the Related Art In recent years, as a revetment for rivers, there have been those in which concrete blocks are used, and those in which wooden rods are assembled in a frame shape and crossing portions are fixed with snails, bolts or the like.

[0003]

The concrete block is of a single size, and when it is laid on a slope or a river bed, there will be no gaps and the habitat for fish and shellfish and aquatic life living in the river will be reduced. I took it away. Therefore, fish nest blocks have been considered for the purpose of providing a refuge place and a habitat for fish and shellfish. However, this fish nest block could provide only a certain size of space because of its uniform shape and size. However, fish and shellfish and aquatic organisms of various sizes live, and the space of this fish nest was not necessarily available to all organisms. Therefore, the woodworking floor where a wooden frame was built and filled with stones of various sizes, such as chestnut stones and crushed stones, to obtain spaces of various sizes,
In addition to the contact between stones, large and small spaces were created, and fish and shellfish and aquatic organisms in proportion to their respective sizes were able to inhabit. However, in the woodworking floor, after several years, the wood corroded and the snails came off, so the frame of the wooden rod was not firmly fixed to the foundation, so the frame would break and be washed away,
If there is a lot of rainfall, the wooden frame has the inconvenience of being washed away by buoyancy.

[0004]

Therefore, the present invention has been proposed in order to eliminate the above-mentioned inconvenience, and the constitution thereof is a concrete substrate 1 having a through hole in the center which becomes narrower as it goes downward. Place the wooden rods 4 on the two opposite sides of the top surface of the, and then place the wooden rods on the remaining two sides.
The wood rods are cross-overlapped and piled up in the same manner, and are stacked in several steps in the same manner.These are inserted into a connecting rod standing on the upper surface of the concrete base or fixed by attaching it, and the concrete base and the wooden frame are integrated. It has been transformed. By doing so,
The wooden frame surely constitutes a strong woodworking floor and does not fall apart, and since stones of various sizes such as rubble and crushed stone are filled inside the wooden frame and through holes, it also resists buoyancy. Don't worry, stones of various sizes, such as quarts and crushed stones, will become habitat for fish and shellfish and aquatic organisms of various sizes by creating spaces of various sizes. If you configure the space that is not filled with stone materials such as
It can provide a habitat for large fish and shellfish.

[0005]

Embodiments of the drawings will be described below. Reference numeral 1 is a concrete base, and two through holes 2 and 2 are provided in the center of the concrete base. Three
Is a connecting rod which is erected in the four corners of the upper surface of the concrete base body 1 and, if necessary, in the middle thereof, and which uses a reinforcing bar 3'or a wooden reinforcing bar or a synthetic resin reinforcing bar 3 ". In this case, the base 1 is passed through and fixed with a nut 31 (see FIG. 8.) The lower portion of the reinforcing bar 3 ′ may be bent into a U-shape 32 and embedded in the base 1 (see FIG. 9). In the case of wood reinforcement and synthetic resin reinforcement 3 ″, it becomes relatively thick. As shown in FIGS. 10 and 11, a hole 11 is provided on the upper surface of the foundation 1 and fitted into this hole 11 and fixed by filling mortar 12 around it. Do you? Figure 1
2, as shown in FIG. 13, a concave groove 33 is provided on the outer periphery of the lower part of the wooden reinforcing bar and the synthetic resin reinforcing bar 3 ″, and the concave groove 1 is formed on the upper surface of the foundation 1.
1, and the bolt 34 screwed from the side surface of the base 1 is fitted and fixed in the groove 33. Alternatively, as shown in FIGS. 14 and 15, a mounting member 35 having a flange portion 37 at the lower portion of the cylindrical flange 36 is attached to the upper surface of the foundation 1, and a wooden rod, a synthetic resin, which is a connecting rod, is attached in the cylindrical flange 36. The lower part of the streaks 3 ″ is inserted and fixed. A bar 4 is placed on two opposite sides of the upper surface of the concrete base 1, and then the two opposite sides which are orthogonal to this are overlapped and placed. When the connecting rod 3 is the reinforcing bar 3 ', the reinforcing bar 3'is inserted through the intersection of the wooden rod 4 and the upper and lower ends are tightened with the nut 31. In the case of the wooden reinforcement and the synthetic resin reinforcement 3 ″, the wooden reinforcement and the synthetic resin reinforcement 3 ″ are attached to the intersection of the wooden rod 4, and the wooden reinforcement, the synthetic resin reinforcement 3 ″ and the wooden rod 4 are bolted. Insert the nut and tighten the nut, or bind it with a metal wire. 6 is a wooden rod 4 with a short portion formed therein to form a space therein. Reference numeral 7 is a hook provided on the opposite side surfaces of the concrete base 1, and the end portion is embedded in the concrete base 1. Reference numeral 8 is a stone material such as a crushed stone and a crushed stone filled in the inside of the wooden rod 4 and the through hole 2.
9 is a plant.

[0006]

Since the present invention has the above-mentioned structure, it is arranged in parallel with a riverbed or a shore of a large number of rivers, and the hooks 7 of the adjacent woodwork sunk are connected with a connecting metal fitting such as a wire or a shackle, and the inside is connected. The stone material 8 is filled and constructed. If necessary, the soil is planted on it and plants are planted on it.

[0007]

According to the present invention, the wooden frame made up of a large number of wooden rods
The concrete base 1 and the connecting rod 3 are integrated, and the stone material 8 is filled inside the wooden frame or the concrete base 1, and the through hole 2 of the concrete base 1 becomes thinner as it goes downward. The weight of 8 is in a state of pressing the concrete base 1 to the lower part, which is well resistant to the flow velocity of a large amount of rainfall and is stable without buoyancy, so that the purpose of revetment is well achieved. Further, since the wooden frame formed of the wooden rod 4 is fixed to the concrete base body 1 by the connecting rod 3, the shape thereof can be maintained well for a long period of time. Since various spaces are held between the space 6 and the stone material 8 inside, fish and shellfish and aquatic organisms of various sizes can inhabit. The present invention has an effect that it can be constructed relatively inexpensively because the upper part is a wooden frame and the lower part is made of concrete. In addition,
As shown in Fig. 5 and Fig. 6, if a short wooden rod 4 is used to form the space 6 inside, large fish and shellfish will be able to live, and it will also become a soil on the woodwork floor. If the plant 9 is planted, it is also environmentally friendly.
