BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence device for wind protection, snow protection, sand protection, sound insulation and the like, and more particularly to a fence device suitable for installation for wind protection when planting a windbreak forest on a coast.

[0002]

2. Description of the Related Art Conventionally, as this type of fence device, a plurality of horizontal members are erected between a plurality of columns established at required intervals, and a net is stretched over these members or a vertical member. There are known rods arranged in rows.

[0003]

However, these known fence devices have a high material cost, such as columns, horizontal members, nets or vertical rods, which make up the fence device. There is a problem of providing an economical and fence device that can achieve the desired effect.

According to the present invention, a steel material is used for the pillars and the horizontal members forming the basic frame structure of the fence device, and the steel members are lined up with the horizontal members while ensuring sufficient strength required for the structure. The above problem is to be solved by adopting round lumber such as thinned wood for the vertical rod to be bridged.

[0005]

According to the present invention, the fence device for wind protection, snow protection, sand protection, sound insulation and the like has the following construction. A plurality of anchor bolts 1 made of steel material such as H steel, which are established at required intervals, embed a required lower end portion 1 'in the foundation concrete 2 and penetrate the lower end required length portion 1'. 3 is buried in the same basic concrete 2. A horizontal member 4 made of a steel material such as an L-shape steel, which is horizontally laid between at least two upper and lower steps between the adjacent columns 1, 1, has a vertical rod 6 made of round wood such as a thinned material on its surface side.
Are arranged in rows with their upper ends set at positions higher than the upper ends of the columns 1. Windproof,
A net 9 of a required mesh made of synthetic resin or metal is stretched according to the purpose of snow protection, sand protection or soundproofing.

[0006] In the above, the column 1 is set up vertically, and the anchor bolts 3 are screwed and buried horizontally in the foundation concrete 2, and the horizontal members 4, 4 laid between the adjacent columns 1, 1 are mounted. Structurally, it is more preferable to construct the upper and lower two-stage horizontal members 4 and 4 at the upper end portion of the columns 1 and the hem portion slightly rising from the ground. Further, when the net 9 is clamped and tightened by a required vertical rod 6, for example, a vertical rod 6 at a position close to the column 1, and a holding rod 11 such as a synthetic resin pipe, the tension of the net 9 is firmly fixed, which is preferable. is there.

Further, the steel column 1 is coated with hot-dip galvanizing and resin coating, and the horizontal member 4 and the horizontal rail 8 made of steel, as well as the bolts and nuts, are coated with hot-dip galvanizing. As for the vertical rod 6 made of wood, the durability of the entire apparatus can be improved by adopting the one which has been subjected to surface preservation and insect repellent treatment.

[0008]

According to the fence device of the present invention, a plurality of anchor bolts are penetrated and fixed to a required length portion at a lower end buried in a foundation concrete, in which columns established at required intervals are made of steel such as H steel. Since the horizontal members buried in the foundation concrete and suspended in at least two levels between adjacent columns are made of steel such as L-section steel, the basic frame structure as a fence device has the necessary strength. We have enough.

Round wood such as thinned wood is used for the vertical rods arranged in line with the horizontal members, and the upper ends of the vertical rods are set at positions higher than the upper ends of the columns. In other words, by making the upper end of each vertical rod higher than the column, i.e., even if the height of the steel column is reduced, it is possible to obtain the desired height of the fence device, and thereby the column and the column The center of gravity of the steel-made horizontal member that was laid on it was held at a low position to stabilize the whole, and in the past, a pillar was installed diagonally or parallel between the upper end of the column and the foundation concrete. What has to be reinforced can be sufficiently supported only by embedding a plurality of anchor bolts in the foundation concrete as described above.

[0010] In general, by using round wood, especially thinned wood, as a vertical rod requiring several times or more the number of pillars or horizontal members, material costs can be reduced and processing work can be facilitated. In addition, since wood is lighter than steel, it is possible to reduce the size of a basic frame structure formed of steel pillars and horizontal members, and to economically build the entire apparatus.

Each vertical rod 6 has its upper end set at a position higher than the upper end of each of the columns 1. Numeral 7 is a tightening tool composed of a bolt and a nut that tightens each vertical rod 6 to the horizontal members 4 and 4. As described above, by setting the upper end of each vertical rod 6 higher than the column 1, the height of the column 1 made of steel is made as low as possible, and the column 1 and the horizontal member 4 made of steel, which is laid on the column 1. , 4 are kept in a low position, and it is possible to construct a fence device of a required height while stabilizing the whole. In addition, conventionally, between the upper end of the column 1 and the foundation concrete 2, The pillars had to be laid diagonally or parallel to reinforce them. However, the necessity was eliminated, and as described above, a plurality of (three in this embodiment) foundation concrete with threaded anchor bolts 3 was used. It was enough to bury it in 2.

Reference numeral 11 denotes a synthetic resin pipe or the like abutting on the surface of the required vertical rod 6, for example, the vertical rod 6 at the closest position along the column 1, so as to sandwich the net 9 between the vertical rod 6 and the column 1. With the holding rod, the vertical rod 6, the net 9 and the holding rod 11 are fastened together by a wire 10.

In the above description, hot-dip galvanizing and resin coating are applied to the steel support 1, and the horizontal support 4 is also made of steel.
It is clear that it is preferable to apply hot-dip galvanization to the rails, horizontal rails 8 and bolts and nuts, and to employ a round rod 6 made of round wood that has been subjected to surface preservative and insect repellent treatment.

[0017]

As is apparent from the above description,
According to the present invention, the following effects can be obtained.

The pillars established at the required intervals are made of steel such as H steel, and a plurality of anchor bolts are fixedly penetrated to the required length at the lower end buried in the foundation concrete, and they are buried in the foundation concrete. At the same time, since the horizontal member horizontally laid between the adjacent columns in at least two stages is made of a steel material such as an L-shaped steel, the basic frame structure as the fence device can sufficiently secure necessary strength.

By making the upper end of each vertical rod higher than the column, in other words, even if the height of the column made of steel is reduced, a fence device of the desired height can be obtained, and thereby, Maintain the center of gravity of the support and the horizontal member of the same steel material suspended in it at a low position, stabilize the whole, in the past, the stay pillar between the upper end of the support and the foundation concrete,
What has to be reinforced diagonally or parallel can be sufficiently supported by simply burying a plurality of anchor bolts in the foundation concrete.

Normally, round wood, especially thinned wood, is used as a vertical rod that requires several times or more the number of columns or horizontal members, so that the material cost can be reduced and the processing work can be easily performed. In addition, since wood is lighter than steel, it is possible to reduce the size of a basic frame structure formed of steel pillars and horizontal members, and to economically build the entire apparatus.

In particular, the pillars and the horizontal members are made of steel, the vertical rods are made of round wood such as thinned wood, and, as described above, the upper ends of the vertical rods are higher than the columns, and the height of the columns is reduced. Therefore, when the fence device of the desired height is built, the center of gravity of the steel column and the horizontal member is lowered, and the required length of the lower end of the column is reduced without the need to construct the pillar as in the past. The entire device can be safely and firmly supported only by embedding a plurality of anchor bolts of the portion in the foundation concrete, and is extremely suitable as a fence device installed for windbreak when planting a windbreak forest on the coast.
