DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden fence and a method of constructing a wooden fence, and more particularly to a wooden fence and a method of constructing a wooden fence on a slope beside a road in a mountainous area or the like.

[0002]

2. Description of the Related Art Conventionally, concrete retaining walls have been formed on slopes beside roads such as mountainous areas to prevent landslides and the like. This concrete retaining wall ensures the daily safety of the surrounding area and can minimize damage even in the event of a natural disaster. However, the conventional retaining wall is made of concrete, and since the surface of the concrete is exposed, the appearance is not natural and does not match the surrounding natural environment.

In order to prevent landslides, a wooden fence made of thinned wood or the like is used instead of the concrete retaining wall. For example, as shown in FIGS. 5 and 6, a conventional wooden fence 30 drives a pile 31 vertically into the ground at a predetermined interval, and a plurality of back logs are vertically inserted into the pile 31. 32 are arranged in the up-down direction, and the back logs 32 and the piles 31 are formed by tying them with a number line 33.

[0004]

However, as described above, the conventional wooden fence has a shape in which back logs are stacked over one surface when viewed from the front, although the problem of not being suitable for the surrounding natural environment has been alleviated somewhat. Therefore, there was a problem that plants and trees did not grow from the surface of the wooden fence, that is, the surface of the back log, and the natural landscape was spoiled in the surrounding mountains where vegetation was growing. In addition, since the logs are stacked on one side as viewed from the front, a large amount of material is required for the wooden fence.

[0005] In the prior art, it is easy to construct a wooden fence on a certain flat slope or to make a straight wooden fence.
Building wooden fences along the terrain was extremely difficult.

[0006] Accordingly, the present invention provides a relatively small number of materials.
The issue is to provide a wooden fence and a method of constructing a wooden fence that can cope well with the surrounding landscape even when constructed in a natural environment, and that can cope with the undulating and curved topography in the front-rear direction. Things.

[0007]

According to a first aspect of the present invention, there is provided a wooden fence comprising: a wooden rod having an opening penetrating in the width direction near an end in the longitudinal direction; A plurality of the wooden bars are alternately shifted and stacked so that the vicinity of the ends of the wooden bars overlap in the vertical direction and the openings are continuous so that a plurality of the wooden bars are arranged side by side at predetermined intervals so as to generate a gap between the wooden bars. It has a fence, a shaft member inserted into the opening continuous above and below the fence, and a retaining member assembled to the fence and protruding from the back surface of the fence.

[0008] Here, as the wood rod, for example, a thinned wood is used. The shaft member is, for example, an iron bar. Further, the number of wood rods arranged in the longitudinal direction is not particularly limited, and may be any number. The length of the timber bar in the longitudinal direction is not particularly limited, but is preferably a length that can cope with a change in terrain. Also, the wood rod may have a rectangular parallelepiped appearance,
By forming the shape on the front surface into a curved surface, it is possible to make it look as if logs are stacked when viewed from the front.

Therefore, according to the wooden fence of the first aspect of the present invention, a plurality of wood rods are arranged side by side at predetermined intervals so that a gap is formed between the wooden fences and the adjacent wood rods. When stacking the wooden rods, the wooden rods are alternately shifted in the longitudinal direction so that the vicinity of the ends of the wooden rods overlap in the vertical direction. In this way, by stacking the wooden rods to form the fence, a plurality of gaps penetrating back and forth are formed. For example, if the upper and lower overlapping portions at one end of the wood bar are set to 1/5 of the length of the wood bar in the longitudinal direction, a plurality of voids having a length of 3/5 of the length of the wood bar in the longitudinal direction are formed. Becomes

When the wooden rods are stacked, the openings formed in the wooden rods are vertically continuous, and a shaft member is inserted through the continuous openings. That is, since the wood rod is supported by the shaft member and is in a connected state, the angle between the adjacent wood rods around the shaft member can be set to an arbitrary angle.

A retaining member is attached to the fence so as to protrude rearward from the back surface of the fence. When the sediment is put on the back side of the fence, the retaining member is attached to the fence. Buried in and fixed.

The wooden fence according to the second aspect of the present invention is the first aspect of the present invention.
In the wooden fence, a top member having a length shorter than the length of the gap is disposed in the gap at the top of the fence body.

Here, the cross-sectional shape of the top member in the width direction is desirably equal to the cross-sectional shape of the wood rod in the width direction in order to unify the appearance of the entire wooden fence.

Therefore, according to the wooden fence of the second aspect of the present invention, in addition to the function of the wooden fence of the first aspect of the present invention, the wooden rod is located in the uppermost space of the fence, that is, the wooden rod and the wooden rod adjacent to the wooden rod. Since the top member is disposed in the space between the fence, the upper surface of the fence is substantially flat. In addition, since the length of the top member is shorter than the length of the gap, a gap is generated between the top member and the wood rod. Therefore, even when changing the angle between the adjacent wooden rods around the shaft member in order to cope with the change in the terrain, the top member and the shaft member can be set to a free angle without abutting. .

According to the third aspect of the present invention, a wooden fence is provided in the first aspect.
Alternatively, in the wooden fence according to any one of claims 2 to 5, the shaft member is a bar having a stop portion formed at one end and a screw portion formed with a nut at the other end. Here, the stop is a stopper for preventing the shaft member from coming off, and is formed to be larger than the diameter of the opening formed in the wood rod.

Therefore, according to the wooden fence of the third aspect, in addition to the action of the wooden fence of the first or second aspect, one end of the shaft member is inserted in a state where the shaft member is inserted into the continuous opening. The nut formed on the other end of the shaft member is screwed while the stop formed on the shaft member is in contact with the bottom surface of the fence body. Thus, the vertically stacked wood rods are sandwiched and fixed between the stop and the nut.

According to a fourth aspect of the present invention, there is provided a method for constructing a wooden fence, wherein a base member is manufactured by inserting a shaft member into each of two openings formed in the vicinity of a longitudinal end of the wooden rod. A plurality of the bases are disposed at predetermined intervals in a posture in which the longitudinal direction of the shaft member is horizontal and the shaft member stands up, and the base member is disposed above the shaft member so as to connect the predetermined base portion and the separate base portion. A base set is manufactured by dropping wood rods from the base set, and then a plurality of wood sticks are sequentially dropped so as to be alternately stacked above the base set, stacked up to the topmost wood stick, and then stacked up and down. The wooden fence is formed by fixing a plurality of wooden rods by fixing means.

Here, the fixing means can be composed of, for example, a stop portion and a screw portion formed on the shaft member, and a nut screwed onto the screw portion.

Therefore, according to the wooden fence of the fourth aspect, when constructing the wooden fence, first, the base is manufactured. That is, the shaft member is inserted into each of the two openings formed in the wood bar. Here, in the case where the fixing means is composed of a stop portion, a screw portion, and a nut, the shaft member is inserted into the opening with the screw portion side formed at one end of the shaft member as the tip. A plurality of the bases manufactured in this manner are arranged at predetermined intervals in a posture in which the longitudinal direction of the wood bar is horizontal and two shaft members are erected. Next, a timber rod is dropped from above the shaft member so as to connect the predetermined base and a separate base adjacent to the base. That is, the opening formed at one end of the wood rod dropped from above is inserted through the shaft member of the predetermined base,
The opening formed at the other end is inserted into a shaft member at a separate base. In addition, a collection of such a continuous base is referred to as a base set.

Thereafter, a plurality of wood rods are sequentially dropped onto the base set so as to be alternately shifted and stacked. In other words, the timber rods dropped first from the top of the base set are located above the timber rods of the base, and the timber rods dropped from above are alternately located above the timber rods connecting the bases. Stagger and stack. Then, after stacking up to the topmost wooden bar, a plurality of wooden bars stacked vertically are fixed by the fixing means. Here, the fixing means
In the case of a structure including a stop portion, a screw portion, and a nut, the wood bar is fixed by screwing the nut to a screw portion formed at one end of the shaft member.

The second basic member 6b has a second opening 11 at a position further inside the opening 10 in the longitudinal direction, although the point that the opening 10 is formed near the left and right ends is common. (See FIG. 4). The inner diameter of the second opening 11 is slightly larger than the outer diameter of the holding member 12 described later.

The top member 7 is disposed in the uppermost space S of the fence 2 so that the upper surface of the fence 2 is substantially flat. The cross-sectional shape of the top member 7 is substantially equal to the basic member 6 and a curved surface is formed on the surface. The length of the top member 7 is set to 56 Cm.

The end members 8 are provided at both ends of the fence body 2. The cross-sectional shape of the end member 8 is substantially equal to that of the wooden bar 6 and the top member 7 and a curved surface is formed on the surface.
The length of the end member 8 is, for example, 20 Cm.
A third opening 14 that penetrates in the width direction is formed in the center of. The inside diameter of the third opening 14 is equal to the inside diameter of the opening 10 formed in the basic member 6. The basic member 6, the top member 7, and the end member 8 are all injected with CUAZ and are subjected to antiseptic treatment.

The shaft member 3 is, for example, an iron bar having an outer diameter of 12 mm and a longitudinal length of 92 Cm. A stop part 15 is formed at one end of the shaft member 3, and a screw part 16 is formed at the other end. The stop portion 15 is a stopper for preventing the shaft member 3 from coming off when the shaft member 3 is inserted into the opening 10 of the basic member 6, and is formed to have a diameter larger than the inner diameter of the opening 10. The screw portion 16 is a male screw formed on the peripheral surface of the shaft member 3, and a nut 17 is screwed to the screw portion 16. In other words, the nut 17 is screwed into the screw portion 16 in a state where the shaft member 3 is inserted into the openings 10 of the plurality (nine in the present embodiment) of the stacked basic members 6, so that the stop portion 15 and the nut 17 allows a plurality of basic members 6 to be fixed. The stop 15 and the basic member 6
By interposing a washer between the base member 6 and the nut 17 and the basic member 6, the basic member 6 can be more securely fixed.

As shown in FIG. 2, the retaining member 4 is for fixing the fence 2 to a slope or the like beside a road, and has one end attached to the basic member 6 of the fence 2 and the other end. It is arranged to protrude to the rear side of the fence body 2. The retaining member 4 is a basic member 6
As in the case of, it has the appearance of a substantially rectangular parallelepiped, the length in the longitudinal direction is, for example, 75 Cm, and the length of the width is the same as that of the basic member 6, for example, 10 Cm. A fourth opening 21 through which the holding member 12 is inserted is formed near one end of the retaining member 4. The holding member 12 is for attaching the retaining member 4 to the fence body 2 and has, for example, an outer diameter of 8 mm and a length in the longitudinal direction of 32 cm.
It is an iron bar. The configuration of the holding member 12 is the same as that of the shaft member 3, and has a stopper 12a formed at one end and a screw portion 12b formed at the other end. The screw portion 12b is a male screw formed on the peripheral surface of the holding member 12, and a nut 18 is screwed to the screw portion 12b. That is, one end of the retaining member 4 is sandwiched between the stacked basic members 6, the second opening 11 of the basic member 6 and the fourth opening 21 of the retaining member 4 are connected, and the second opening 11 and the fourth opening 21 are connected to each other. By screwing the nut 18 into the screw portion 12b with the holding member 12 inserted, the retaining member 4 is formed by the stop portion 12a and the nut 18.
Can be fixed.

The vicinity of the distal end (the other end) of the retaining member 4 protruding rearward is connected to the basic member 6 disposed on the upper side of the fence 2 via a supporting member 5. Support member 5
Is a member made of iron and includes a fixing portion 5a, a support rod 5b, and a mounting portion 5c. The fixing portion 5a is a steel plate having a substantially elliptical cross section, and is fixed to the upper surface of the basic member 6 with a nail or the like.
The mounting portion 5c is a plate-shaped steel plate, and is fixed to a side surface of the retaining member 4 with a nail or the like. The support rod 5b has an outer diameter of 12 mm.
It is a bar made of iron of mm, one end of which is fixed to the fixing part 5a and the other end of which is fixed to the mounting part 5c by welding or the like. in this way,
By providing the support member 5, the force applied to the shaft member 3 can be suppressed, and the deformation of the shaft member 3 can be prevented. In addition, as shown in FIG. 2, if the reinforcing member H is provided laterally so as to connect the top surfaces of the plurality of retaining members 4, the strength can be further improved.

Next, a method of constructing the fence 1 of the present embodiment will be described. When constructing the wooden fence 1, first, the shaft members 3 are respectively inserted into the two openings 10 formed in the second basic member 6b.
Is inserted from below. Specifically, the shaft member 3 is inserted with the screw part 16 side formed at the other end of the shaft member 3 as a tip. In this way, the base 20 is constituted by one second basic member 6b and the two shaft members 3 inserted through the second basic member 6b. Then, the manufactured plurality of bases 20 are
A plurality of the basic members 6b are arranged at predetermined intervals in a posture in which the longitudinal direction of the basic member 6b is horizontal and the two shaft members 3 are erected.

Next, as shown in FIG.
Then, the first basic member 6a is dropped from above the shaft member 3 so as to connect the adjacent separate base portions 20. That is, the shaft member 3 of the predetermined base 20 is inserted into the opening 10 formed at one end of the first basic member 6a (connecting member) dropped from above, and the other end of the first basic member 6a (connecting member). The shaft member 3 of the separate base 20 is inserted through the opening 10 formed in the base member 20. The collection of the continuous bases 20 and the like in this manner corresponds to a base set of the present invention. Here, the base 20 is a first basic member 6a (connecting member) dropped from above.
To the base 2 in other words,
Since 0 is pivotally supported by the first basic member 6a (connection member), the angle of the base 20 with respect to the first basic member 6a (connection member) can be set to an arbitrary angle. That is,
As shown in FIG. 3, the fence 2 can be constructed in a desired shape so as to match the topography of the installation location.

After the plurality of bases 20 are all connected to form a base set, the second basic member 6b is further dropped from above the base set so as to be located above the base 20. As a result, two second basic members 6b and one first basic member 6a are stacked in the vertical direction. Next, the retaining member 4 is attached. Specifically, the second basic member 6 of the base 20
b, and one end of the retaining member 4 is inserted between the second basic member 6b further dropped from above the base set, and the second opening 11 of the second basic member 6b and the fourth opening 21 of the retaining member 4 are inserted. While the holding member 12 is inserted into the first opening 11 and the fourth opening 21 from below, the second basic member 6
The nut 18 is screwed onto the threaded portion 12b protruding from the upper surface of the b.

Thereafter, the plurality of first basic members 6a are alternately shifted and stacked, such as first above the first basic member 6a and then above the second basic member 6b. In addition, every other end member 8 is dropped into the end of the fence body 2 so that the end member 8 is disposed below the first basic member 6a.

Then, after stacking up to the uppermost first basic member 6a, the top member 7 is disposed in the gap S generated at the uppermost stage. The top member 7 is fixed to the upper surface of the first basic member 6a one step below the uppermost step (the eighth step from the bottom in this embodiment) with a nail or the like. Here, since the length of the top member 7 in the longitudinal direction is shorter than the length of the gap S, the top member 7 and the top member 7
A gap is formed between the first basic member 6a and the adjacent first basic member 6a. Therefore, as shown in FIG. 3, when the fence 2 is constructed according to the terrain, the end of the top member 7 and the end of the first basic member 6a can be constructed in a free shape without abutting.

Thereafter, the plurality of basic members 6 and the end members 8 stacked vertically are fixed. Specifically, the shaft member 3
A nut 17 is screwed into a screw portion 16 formed at the other end of the nut. Thereby, the basic member 6 and the end member 8 are connected to the nut 1
7 and the stopper 15 of the shaft member 3 are sandwiched and fixed. Next, the fixing portion 5a of the support member 5 is fixed to the upper surface of the first basic member 6a disposed on the top of the fence body 2, and the mounting portion 5c of the support member 5 is mounted on the other end of the holding member 4. Thus, the upper part of the fence 2 and the retaining member 4 are connected via the support member 5. Further, the reinforcing member H is attached to the upper surface of the other end of each of the retaining members 4 with a nail or the like so that the reinforcing member H is provided horizontally across the plurality of retaining members 4. Thus, the construction of the wooden fence 1 is completed. Note that the wooden fence 1 is disposed with the surface of the fence body 2 inclined as shown in FIG. Further, when earth and sand D is put into the back side of the fence body 2, the retaining member 4, the support member 5, and the reinforcing member H are buried in the earth and sand D, and the wooden fence 1 is fixed. The second basic member 6b of the base 20, which is the lowermost stage of the fence 2, is also buried in the earth and sand D, like the retaining member 4 and the supporting member 5. In FIG. 2, K is a side groove.

As described above, the fence body 2 of the wooden fence 1 of the present embodiment is
Is provided with a plurality of basic members 6 at predetermined intervals so as to form a gap S between adjacent basic members 6.
Are stacked alternately in the longitudinal direction, so that a plurality of voids S penetrating back and forth can be formed in the fence body 2. Therefore, after construction of the wooden fence 1, there is a very high possibility that plants such as plants will grow through the gap S. That is, when plants grow from the space S, the plants can be seen on the surface of the fence body 2, and a landscape that matches the landscape of the surrounding mountains can be created. By arranging a greening mat or the like in the gap S,
Plants can be surely grown. Further, rainwater or the like can be discharged through the gap S, and the durability of the wooden fence 1 can be improved. Furthermore, since the basic member 6 is disposed so that the gap S is generated, the material cost can be reduced as compared with the conventional wooden fence.

Further, the basic member 6 of the wooden fence 1 of the present embodiment.
Since the shaft member 3 is supported by the shaft member 3, the angle between the adjacent basic members 6 around the shaft member 3 can be set to an arbitrary angle. For this reason, it is possible to cope with the terrain of a site having undulation in the front-rear direction or a curved site.

In the wooden fence 1 of the present embodiment, since the top member 7 is disposed in the uppermost space S of the fence 2, the fence 2
Can be made substantially flat, and the appearance can be improved. Moreover, since the length of the top member 7 is shorter than the length of the gap S, a gap can be formed between the top member 7 and the basic member 6 within a range where the top member 7 and the basic member 6 do not abut. The fence body 2 can be changed to a shape that matches the terrain.

In the wooden fence 1 of this embodiment, the nut 17 is screwed into the screw portion 15 formed at one end of the shaft member 3, and the basic member 6 is fixed between the nut 17 and the stop portion 1. Therefore, it can be easily assembled.

When constructing the wooden fence 1 of the present embodiment,
The basic members 6 can be stacked by simply dropping the basic members 6 from above the shaft members 3 so that the shaft members 3 are erected and the shaft members 3 are inserted into the openings 10 formed in the basic members 6. Since it can be done, there is no need for a pile driving operation for hitting a single pile tree to the ground as in a conventional wooden fence or a fixing operation for tying a back log with a line, so that the wooden fence 1 can be easily manufactured.

Incidentally, the dimensions shown for the wooden fence 1 in the above embodiment are merely examples, and even if other dimensions are used, the wooden fence 1 will be described.
What is necessary is just to have the same effect as above. Further, the number of the basic members 6 to be stacked is not particularly limited, and may be appropriately set according to the topography, environment, and the like.

Although the wooden fence 1 of the above embodiment is provided with the supporting member 5, the supporting member may not be provided if the strength of the shaft member 3 is sufficient.

[0041]

As described above, in the wooden fence of the first aspect of the present invention, a plurality of voids penetrating back and forth are formed in the fence body, so that plants such as plants can grow through the voids S. Extremely high. Therefore, a landscape that matches the landscape of the surrounding mountains can be created. Further, rainwater or the like can be discharged through the gap, and the durability of the wooden fence can be improved. Furthermore, since the wooden rod of the wooden fence is supported by the shaft member, the angle between the adjacent wooden rods around the shaft member can be set to an arbitrary angle. For this reason, it is possible to easily cope with the terrain of a site having undulation in the front-back direction or a curved site.

According to the wooden fence of the second aspect, in addition to the effect of the wooden fence of the first aspect, the ceiling member is disposed in the uppermost space of the fence body, so that the appearance can be improved. In addition, since a gap is formed between the top member and the wooden bar, the fence can be changed into a shape suitable for the terrain within a range where the top member and the wooden bar do not abut.

According to the third aspect of the present invention, in addition to the effect of the first or second aspect of the present invention, a plurality of wooden fences are stacked by simply screwing a nut to a screw formed at one end of the shaft member. It is possible to easily fix the timber rods.

According to a fourth aspect of the present invention, there is provided a method for constructing a wooden fence, comprising: erecting a shaft member, and dropping the timber rod from above the shaft member so that the shaft member is inserted into an opening formed in the timber rod. Thus, since the wooden rods can be stacked, the wooden fence can be easily manufactured.
