Description

  The present invention relates to a wooden fishing reef. More specifically, the present invention relates to a wooden reef that uses thinned wood and maintains a long-term fish collection effect.

  Many fishing reefs currently in use are mainly made of concrete or steel as the main frame material, and thinned wood is attached to the frame material. However, the logs will decay and disappear in about 3-5 years. And since the log is not replaced, only the subsequent concrete and steel frames cannot be expected to establish seaweed and shellfish, so the fish collection effect as a fishing reef cannot be sustained. The fish collection effect becomes higher after about five years from the installation of the fishing reef, but at this time the logs with high fish collection effect will be destroyed, so the installed fishing reef will be wasted. However, it is also expensive to install a new reef.

  On the other hand, there is a need for thinning and effective use of thinned wood to protect forests. However, the use of thinned wood for fishing reefs is mostly limited to attaching a log to a frame material, so that thinned wood is not fully utilized.

By the way, conventional fishing reefs range from large ones to small ones, and also have various shapes and are often quite angular. If there are horns or protrusions on the reef, the fishing baskets and fish nets will be caught and will not come up.
Ironically, there are aspects of the reef for fisheries that hinder fisheries, and this is a problem that must be solved.

In view of the above circumstances, the present invention provides a wooden fishing reef that uses thinned wood and gives continuous utilization so that the fish collection effect of the fishing reef can be demonstrated for a long period of time, and does not hinder the lifting of the basket or net as a fishing tool. The purpose is to provide.
The present invention has a socio-economic purpose of promoting the use of thinned wood to protect and recharge forests, and that can be manufactured using general-purpose technology and lead to the activation of local industries.

The wooden fishing reef of the first invention is a horizontal rail having a plurality of wood panels as a main material, an upper frame body and a lower frame body each having four sides, and four struts having a plurality of wood panels as a main material. and reef body assembled into cubes by combining the lower frame body and the top frame, Ri replacement reef material and Tona with freely arranged thinned wood detachably in the inner space of the reef body, wherein Each of the horizontal rail and the support column has a metal bar in the center, a wood panel is arranged around the metal bar, and is fixed by a metal band .
According to a second aspect of the present invention, there is provided the wooden fishing reef according to the first aspect, wherein the replacement fishing reef material is obtained by passing a metal rod through a thinned material hollowed out in a hollow. An engaging portion that can be detachably hooked to the stopper is formed .
The wooden fishing reef of the third invention is characterized in that, in the first invention, at least four corners on the upper surface side of the fishing reef body are formed in a rounded shape.

According to the first invention, the following effects are obtained.
a) Since the main body of the reef is wood, the fish collection effect is high.
b) Since the replacement reef material is also made of thinned wood, the effect of collecting fish is enhanced.
c) Since the thinned wood can be exchanged, the fish collection effect can be maintained for a long time by replacing it with a new one every few years.
d) Since the horizontal rail and the column have a metal rod inside, and the specific gravity is increased, it can be set in the sea.
e) Since the wood panel around the metal bar can be manufactured by a general processing facility, a fishing reef can be manufactured at low cost.
According to the second invention, the metal rod of the replacement reef material has a locking portion at the end, which can be freely attached to and detached from the locking material on the fishing reef body side. Can be easily exchanged with replacement reef materials .
According to the third invention, since the four corners of the upper surface of the reef body are rounded, even when a basket, a fish net or the like, which is a fishing tool, is put in the sea, it is not caught when it is pulled up.

It is a perspective view of the wooden fishing reef A which concerns on one Embodiment of this invention. It is a top view of the wooden reef A of FIG. It is a front view of the wooden fishing reef A of FIG. It is a side view of the wooden fishing reef A of FIG. It is a longitudinal cross-sectional view of the horizontal rails 1a and 2a and the support | pillar 3. FIG. It is a VI-VI line arrow longitudinal cross-sectional view of FIG. (A) is an enlarged sectional view of a pair of support columns 3, (B) is an enlarged perspective view of a band 6 and a horizontal bar 9, and (C) is an enlarged sectional view of a replacement reef material 10. It is a supplementary point explanatory drawing of the replacement fishing reef material.

Next, an embodiment of the present invention will be described with reference to the drawings.
The basic structure of the wooden fishing reef A according to the present invention will be described with reference to FIGS.
The wooden fishing reef A has a hollow box shape. Specifically, it is a frame structure in which an upper frame body 1 and a lower frame body 2 assembled in a quadrangular shape are coupled to each other by four support columns 3.

The upper frame 1 is composed of four horizontal bars 1a, and each horizontal bar 1a has a plurality of wood panels as a main material.
The lower frame 2 is composed of four horizontal rails 2a, and each horizontal rail 2a is mainly composed of a plurality of wood panels.
The four struts 3 are also mainly composed of a plurality of wood panels.

The crosspieces 1a constituting the upper frame 1 and the upper part of the support column 3 are connected to each other by a corner member 4. The corner member 4 is a general structural rolled steel or a metal such as cast forging.
The corners of the corner member 4 are formed in a rounded shape. This roundness can prevent a fishing tool such as a basket or a fish net from being caught.

  The lower frame 2 is connected to each other by the corner members 5 between the horizontal rails 2a and the lower part of the column 3. The corner member 5 is a general structural rolled steel or a metal such as cast forging. The corner portion of the corner member 5 does not need to be rounded while being angular.

Next, the detailed structure of the cross rails 1a and 2a and the support column 3 will be described with reference to FIG.
The horizontal rails 1a and 2a and the support column 3 are mainly made of wood panels. Various wood panels can be used without particular limitation, but the following are preferable.
B) A thin plywood cut from coniferous wood, and a single plywood made by laminating a plurality of boards with adhesives alternately in the fiber direction.
B) A wood chip made by heat compression molding into a single board, and a plurality of these are laminated.

The above-mentioned a) and b) are preferably those having a strength that can be used for a structural material by further performing a fungus control treatment.
The laminated state for the structural panel is fixed with an adhesive. However, fixing with the metal band 6 is preferable because the service life in the sea is increased. Further, when the adhesion effect is weakened, the wood panel can be prevented from being lifted.
Coniferous thinning plywood for timber panels does not require the high strength and shade required for building materials.
The above wood panels can be used for thinned C materials (small-diameter wood, bent wood, branches, etc.), driftwood, edge materials, construction waste, etc. Use of thinned wood can be promoted. In addition, effective utilization of driftwood, which is a problem in the Sea of Japan and Okinawa, is possible.

  Metal bars 1b, 2b and 3b having a square cross section are placed in the center of the horizontal rails 1a and 2a and the column 3. The metal is preferably square steel such as general structural rolled steel. The reason why the metal bars 1b, 2b, and 3b are used is to increase the rigidity of the horizontal rails 1a and 2a and the support 3 and to increase the specific gravity of the entire fishing reef and to cause self-sinking in the sea.

The cross rails 1a and 2a and the column 3 are coupled to the corner members 4 and 5 by inserting the end portions of the metal bars 1b, 2b and 3b into the holes formed in the corner members 4 and 5 and using the bolts 7. Bonding is used together. The bolt 7 is inserted into the upper corner member 4 from the side through a through hole, penetrates the hole at the upper end of the metal bar 3b, and the corner member 4 and the metal bar 3b are screwed together.
In addition, the lower corner member 5 is inserted from the side through a through hole, penetrates the hole at the lower end of the metal bar 3b, and the corner member 5 and the metal bar 3b are screwed together. In this way, the cross rails 1a, 2a and the support column 3 are firmly coupled to the corner members 4, 5 by the bolts 7.

Due to the basic structure described above, the internal structure of the wooden fishing reef is a large space, and the replacement reef material 10 made of thinning material is detachably disposed in this internal space.
That is, as shown in FIG. 6, a horizontal bar 9 as a locking member is attached between adjacent columns 3 and 3. A replacement reef material 10 is passed between two parallel horizontal bars 9 and 9.
In the present embodiment, the replacement reef material 10 is provided in two stages, and the passing direction is orthogonal to each other as shown in FIGS. 3 and 4. Moreover, the replacement reef material 10 may be provided with three or more stages.

A means for attaching the replacement reef material 10 will be described with reference to FIG.
As shown in FIGS. 4A and 4B, brackets 8 are fixed to the band 6 fixed to the support columns 3, 3, and a horizontal bar 9 is inserted into the two brackets 8, 8. Yes. Both ends of the horizontal bar 9 may be fixed to the brackets 8 and 8 by welding or other means.

The replacement fishing reef material 10 is obtained by passing a thinned wood 13 that is hollowed out in a single metal rod 11. The metal rod 11 is bent at both ends to form a locking portion 12. One to several thinned logs 13 are passed through one metal bar 11. The illustration shows two examples.
The thinned wood 13 is selected from thinned wood having a size that can be processed into a round wood.

  As shown in FIG. 7, both ends of the metal rod 11 of the replacement reef material 10 are bent to form a locking portion 12. Can be exchanged. That is, since the structure is simple and the switching work is easy, the replacement fishing reef material 10 can be easily replaced by diving a diver in the sea.

FIG. 8 shows a procedure for replacing the replacement reef material 10.
(A) In the figure, 10a shows five of the replacement fishing reef materials 10a that are attached first.
Normally, after about 5 years have passed, the replacement reef material 10a has decayed, and the state is shown in FIG. At this time, a new replacement reef material 10b is replenished.
When about five years have passed, the previous replacement fishing reef material 10b decays, so a new replacement fishing reef material 10c is replenished as shown in FIG. In this way, the wooden reef can be continuously used by repeating the replacement and replacement.

  The above replenishment replacement is an example, and the present invention is not limited to this. Instead of exchanging them all at once, you may exchange them for each broken item. It is also possible to just replenish the new one without removing the old one.

In the embodiment described above, the space between the four horizontal bars 2a constituting the lower frame 2 remains hollow, but a metal rod is attached between the four horizontal bars 2a, and the wire mesh is attached. You may place cracked stones, etc., which will be used to improve the bottom quality, on the wire mesh.
If it does in this way, the bottom of the wooden fishing reef of the present invention can also exhibit a fish collection effect.

As described above, a conventional general reef is made of concrete or steel, and must be manufactured in a factory with facilities, and can only be manufactured by a specific company.
However, since all the reef members of the present invention can be procured in the general market, if there is a simple crane, welding technology, and a suitable production area, it can be used by ironworks, sawmills, construction companies, etc. Can be manufactured and assembled. For this reason, it can contribute to activation of local industry.
