DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS. FIG.
FIG. 2 is a diagram illustrating a cut surface of the timber for fence 1 in the present embodiment. As the wood 1 for fence, a log of about 60 mm in diameter obtained by shaving the outer skin of Akita cedar or an outer diameter of about 60 m
A circular wood of Akita cedar which has been cut into a circle and processed into a circle (both are referred to as columnar wood in this specification) is used.
Then, in order to stabilize the cylindrical timber so that it does not rotate, the outer surface 4 is cut from the outer peripheral surface toward the center at a distance of about 5 mm in the longitudinal direction over the entire length to obtain a cut surface (flat surface) 5. Next, a groove 11 for mounting an iron reinforcing core material is cut out over the entire length in the longitudinal direction to obtain the fence wood 1. This groove 11 cuts out a width of 20 mm and a depth of 45 mm based on the cut surface 5. In this state, it can be used as it is as wood for fences, but in this embodiment, wood that has been subjected to preservative treatment by injecting resin after processing is used. In addition, regarding the resin injection, after forming the groove 11, before forming the cut surface 5, and after forming the cut surface, the groove 1 is formed.
Before forming 1 and the state of raw wood before processing into a cylindrical shape,
It may be performed in any of the states.

FIG. 2 is a cross-sectional view showing a state in which a reinforcing core 2 is attached to a fence wood 1. Reinforcing core 2 is 4
A square steel tube of 0 mm × 20 mm is used, and its surface is galvanized to enhance corrosion resistance. In order to fix the wood for fence 1 to the reinforcing core 2, an adhesive 6 indicated by a dotted line over the entire length of the outer peripheral surface of the reinforcing core 2.
Has been applied.

FIG. 3 is a sectional view of the reinforcing wood 1 when a 5 mm × 20 mm padding 3 is attached. As shown in FIG. 3, by attaching the embedded wood 3 to the exposed surface of the reinforcing core material 2 with an adhesive 6 indicated by a dotted line, the reinforcing core material 2 is not directly exposed to the outside air or the weather, and the durability is improved. Can be further enhanced. Further, by bonding the side surface of the groove 11 provided in the fence wood 1 to the buried tree 3, the groove 11 is dried and dried.
Can be prevented from being easily separated from the fence wood 1 and the reinforcing core 2. In this way, the appearance is not different from ordinary wood, and a high-strength reinforcing wood can be constructed.

FIG. 4 is a diagram showing the most basic configuration of a fence using the reinforcing core 2. First, a hole 8 for installing a vertical column 9 using the reinforcing core material 2 is dug in the ground 7, and the vertical column 9 is constructed vertically at an interval of 1800 mm. The concrete 1 is placed in the space between the vertical columns 9 and the holes 8
Pour 9 and stabilize vertical column 9. The concrete 19 is made to be flush with the ground 7. On the vertical column 9, a horizontal column 10a similarly using the reinforcing core material 2 is provided on the upper surface,
10b is attached to the side, the joint is heated, welded and fixed. If the length of the horizontal column 10 is insufficient, a joint 12 having the same outer diameter as the inner diameter of the horizontal column 10 is inserted between the horizontal columns 10 to connect and fix the horizontal column 10.

FIG. 5 shows a vertical column 29 using a reinforcing core material 22.
FIG. 11 is a diagram showing another method of fixing the. The reinforcing core material 22 used here is a square steel pipe of 20 mm × 20 mm, which is buried deep underground 7
Fix with. In the vicinity of the surface of concrete 19, the inner diameter is 6
A cylindrical depression 55 having a diameter of 9.1 mm and a depth of 100 mm is formed. The reinforcing core material 22 vertically built in this way
It is wrapped around the outside with a fence wood 1 and an outer surface 4 so that the appearance becomes a natural wood. The outer diameter of the vertical pillar 29 composed of the fence wood 1 and the outer surface 4 is 60 mm.
It is. The fixing of the fence lumber 1 and the outer surface 4 is shown in FIG.
As shown in FIG. 7, the reinforcing core member 22 and the outer surface 4 are fixed with screws 27. Moreover, you may fix using an adhesive together. FIG. 7 shows a side view of the vertical column 29. A cut 25 for engaging the horizontal column is provided in the center of the vertical column 29.

The lower part of the columnar wood has a cylindrical recess 5.
5 to form a donut-shaped gap of about 4.5 mm. If this is left as it is, the strength will decrease, so that dry sand 60 is filled here. By doing so, not only the reinforcing core material 2 but also the columnar wood composed of the fence wood 1 and the outer surface 4 are firmly held. On the other hand, when it becomes necessary to remove the cylindrical wood, the sand 60 can be easily removed by washing it out with a water flow. Accordingly, when the fence wood 1 is corroded or damaged, the reinforcing core 22 is
As it is, only the outer wood part can be easily replaced.

Next, another fixing method using a plate will be described with reference to FIG. This method relates to the case where a fence is built on existing concrete 19. In this method, a 250 mm × 250 mm steel plate 80 is used. At the center of the plate 80, a height of 1
A cylinder 85 having a diameter of 00 mm and an inner diameter of 69 mm is attached by welding or the like. The ends of the vertical columns 29 (the reinforcing core material 2 and the fence wood 1 surrounding the core material 2 and the outer surface 4) are inserted into the cylindrical cylinder 85. Since the outer diameter of the columnar timber is 60 mm, a gap of 4.5 mm is formed, and sand 60 is filled therein to fix the columnar timber. In the present embodiment, the cylinder 85 is used as the protruding portion having the concave portion. You may use it. The fence can be decorated by adopting various shapes of tubes. Also, the cylinder 85
May have other sizes such as 15 mm, 20 mm, and 25 mm. Generally, the higher the, the more stable the columnar wood. When removing the sand 60, it is sufficient to wash it with a water flow similarly to the above example. This plate 80
Existing concrete 1 with o-ol anchor 88
Fix to the ground surface such as 9th. According to this method, it is possible to construct a fence in a place where concrete, asphalt, stone, brick, and the like are already stretched and a hole cannot be dug. The plate 1 located in the cylinder 85
9, or a through hole for draining water may be provided in the lower end side surface of the cylinder 85 to prevent water such as rain from accumulating in the cylinder 85. Like the reinforcing core 2, the plate 80 and the cylinder 85 may be galvanized to increase corrosion resistance, or may be made of stainless steel.

FIG. 9 shows a state in which the fence wood 1 and the burying tree 3 are actually attached to a fence made by using the reinforcing core material 2, and FIG. FIG. The vertical column 90 and the horizontal columns 100a and 100b are constructed using the reinforcing core 2. The vertical columns and the horizontal columns 100a and 100b are firmly fixed by welding. The vertical column 90 and the horizontal column 100b may be provided with cuts that engage with each other. In addition, horizontal column 1
00a is welded in a state of being placed on the upper end of the vertical column 90. Then, an adhesive 6 is applied to the outer peripheral portions of the vertical pillars 90 and the horizontal pillars 100 a and 100 b using the reinforcing core material 2, and is mounted so as to be sandwiched by the grooves 11 of the wood 1 for fence. At this time, if the fence wood 1 is longer than the reinforcing core 2, the fence wood 1 is cut to adjust the length.

Next, the embedded wood 3 coated with the adhesive 6 is mounted on the exposed portion of the groove 11 and the reinforcing core 2 from the opposite side of the mounted fence wood 1 and fixed by bonding. . Attachment of the fence lumber 1 at the intersection of the vertical column 90 and the horizontal column 100b requires some contrivance. For example, vertical column 1
First, the wood for fence 1 and the buried wood 3 are attached first, and a notch for engaging with the horizontal column 100b is provided in advance at the intersection of the wood for fence 1 so that the reinforcing core material can be externally provided. 2 can be prevented from being exposed.

Since the length of the timber is finite, when attaching the fence wood 1, it may be necessary to provide a joint portion that joins with the next fence wood 1. Rather than arranging, it is also possible to reinforce by a method such as combining uneven surfaces on the contact surface.

FIG. 11 (a) is a view showing each part in the case where the outer surface 4 which has been once cut is used to re-attach it along the cut surface 5, and FIG. 11 (b) shows a state where the outer surface 4 is attached. It is sectional drawing. The outer surface 4 cut to obtain the cut surface 5 is bonded to the fence wood 1 or the fence wood 1 and the burying wood 3 by using an adhesive 6 also indicated by a dotted line, so that the outer surface 4 has a normal appearance. It is exactly the same as cylindrical wood.

In this embodiment, as shown in FIG. 12 (a), the reinforcing core 2 and the fence wood 1, the reinforcing core 2 and the buried tree 3, the fence wood 1 and the buried tree 3 are indicated by dotted lines, respectively. Although the adhesive 6 is used, the adhesive 6 may be used only for the fence wood 1 and the embedded wood 3. FIG. 12B is a cross-sectional view when the adhesive 6 is not used for the reinforcing core 2. If the fence wood 1 and the reinforcing core 2 are not fixed with the adhesive 6, the play between the fence wood 1 and the reinforcing core 2 is reduced, and the fence wood 1 is connected to the reinforcing core 2. And push it in.
In this case, the reinforcing core material 2 is not bonded to the fence wood 1 and the embedded wood 3 with an adhesive, so that when the fence wood 1 needs to be replaced due to aging or the like, the fence wood is not used. There is an advantage that the wood 1 can be more easily replaced by processing such as cutting the wood 1 in the longitudinal direction and removing the embedded wood 3. FIG. 12 (c) shows that the play between the fence wood 1 and the reinforcing core 2 is reduced and the fence wood 1 is pushed into the reinforcing core 2 without using an adhesive as in FIG. 12. , And the contact surface between the fence wood 1 and the buried tree 3 is fixed with an adhesive. Also,
Although not shown, the fence wood 1 may be fixed to the reinforcing core 2 with screws or the like.

In the present embodiment, the timber 1 for the fence is made of cylindrical wood. However, it is not always necessary to use cylindrical wood, and it is also possible to make reinforced wood from square wood as shown in FIG. Alternatively, a hexagonal prism material or an octagonal prism material may be used as the fence wood 1. As described above, by forming a flat surface on the outer peripheral surface of the fence wood 1, there is an advantage that the material is less likely to be deformed as well as excellent in design as compared with the case of using columnar wood.
1 In addition to columnar wood and square wood, even wood with sculptures or other designs such as totem poles,
There is no problem as long as the space for the groove 11 can be secured for the reinforcing core 2 and the buried tree 3.

In the present embodiment, the preservative treatment is performed after the grooves 11 are formed in the fence wood 1. However, the grooves 11 may be formed using preservative wood. As a method of the preservative treatment, there are a method of injecting a resin into wood, and a pressure injection method of applying pressure to wood soaked in a chemical to penetrate the chemical. The reinforcing core material 2 is made of an iron material, but may be aluminum, copper, or the like. In addition, an example in which the inside is hollow is taken as an example, but this is not essential. Fill 3
Instead of cedar, other wood such as cypress and zelkova, or non-wood such as plastic can be used.

In the present embodiment, welding is used as a method for fixing the vertical and horizontal columns, but other methods such as fixing with screws or combining cuts with irregularities are also possible. In the present embodiment, the joint 12 is used for fixing between the horizontal columns. However, a method such as fixing with a screw or welding can be selected. As a method of assembling the fence, first, the reinforcing core 2
There is also a method of embedding fences into fence wood 1 to make reinforcing wood and then assembling the fence. However, in consideration of labor such as processing, the reinforcing core 2 used in this example is used first.
After assembling the framework of the fence, the wood for fence 1
The method of attaching is more convenient.

The mounting direction of the fence wood 1 is not particularly limited. For example, in the case of a fence for preventing entry and exit of a person, if the burying tree 3 is attached along the side where no person can enter, there is no unnaturalness in appearance. When the outer surface 4 that has been cut once is to be attached again, the padding 3 may be omitted.

FIG. 14 is a diagram showing a state of a fence having a design in which a vertical lattice 110 is attached and fixed between a horizontal column 100a and a horizontal column 100b. 4 is similar to the basic fence shown in FIG. 4, except that both ends of the vertical lattice 110 are welded to the horizontal columns 100 a and 100 b and are parallel to the vertical columns 90. When attaching the fence timber 1 to such a fence, the horizontal pillar 10
The fence lumber 1b to be mounted on 0b requires time and effort such as cutting the fence lumber 1b by the size of the vertical lattice 13 when mounted from the side. The grid of the fence is not limited to vertical and horizontal, but may be diagonal.

FIG. 15 shows an example of a fence including a diagonal lattice. The oblique grid 120 can also be dealt with by cutting the fence wood 1d obliquely from the beginning or considering the mounting direction. 0

In each of the above-described embodiments and modifications, the reinforcing core material 2 has a size of 140 mm × 20 mm or 20 mm.
Although the case where the square steel pipe of mm × 20 mm is used and the timber for fence 1 having a diameter of 60 mm is used has been described, for example, a fence having a high strength as a fence, such as a fence of an observation deck, a fence around a pond, and a fence around a lake, has been described. When necessary, the diameter of the reinforcing core 2 is 30 mm × 30 mm, the diameter of the fence wood 1 is 80 mm, and when the strength is further increased, the diameter of the reinforcing core 2 is 40 mm × 40 mm. The diameter of the fence wood 1 may be 100 mm. In the case where the strength of the fence is also given to the fence wood 1 by the sand 60 using the hollow 85 of FIG. 5 or the cylinder of FIG. 8, the size of the reinforcing core 2 has been described in the embodiment. 20
mm x 20 mm, and the fence wood 1 is 80 mm,
Any size such as 00 mm and 120 mm may be used.
In this case, the strength of the fence can be further increased by increasing the depth of the depression 85 and increasing the height of the cylinder 85. 1 In any case, the size of the reinforcing core material 2 and the size of the fence wood 1 can be selected from arbitrary values according to the strength required for the fence.
