Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fence which is laid on an outer periphery of a site such as a substation or a highway to prevent a person or an animal from entering. In particular, the present invention relates to a fence capable of easily performing operations, management, and the like of manufacturing, storage, transportation, and laying.

[0002]

2. Description of the Related Art Conventionally, a fence is composed of a net material and a support made of a welded wire mesh, and the net material is attached between the supports. Recently, there has been known a net material in which the upper and lower edges are bent into a cylindrical shape or a prism shape to reinforce the resistance to a vertical load.

In recent years, the demand for fences has been diversified, and for example, the demand for large fences has been increasing in order to prevent intrusion of people, animals, and the like into substations and expressways. .

[0004]

However, according to the conventional fence, the net material attached between the columns is usually composed of a single net material. In addition, there is a problem that each work such as laying and management becomes difficult.

Further, as the height of the fence increases, deformation of the net material tends to occur due to its own weight. To prevent this, it is conceivable to increase the wire diameter of the net material or reduce the mesh pitch. . However, there is a problem in that these measures increase the cost of manufacturing the net material and increase the cost of the fence.

Further, at present, protection of the natural environment and harmony between industrial products and the environment are required, and fences are not an exception, and a design that is integrated into a living space is required. Under such circumstances, the development of a fence with rich design is desired.

[0007] Accordingly, the present invention has been made in view of such problems, and its object is to provide a large-sized
It is an object of the present invention to provide a fence that can easily perform each operation and management such as production, storage, transportation, and laying, does not require cost, and can simultaneously improve design and reinforce net material.

[0008]

In order to solve the above-mentioned problems, a fence according to the present invention is a fence having a net material attached between supports, wherein the net material attached between the supports has a plurality of vertically splittable net materials. It is characterized by being composed of members. Further, the net material attached between the columns may be configured by a member that can be divided into two or three parts in the upper and lower parts.

[0009] Since the net material of the fence can be divided into a plurality of members, even a large fence can easily perform operations such as manufacturing, storage, transportation, and laying, and management. Since the shape of each member constituting the net material can be reduced, deformation of the net material due to its own weight can be prevented.

Further, in the above-mentioned fence of the present invention, the net member attached between the columns may be constituted by an uppermost member, a lowermost member, and one or a plurality of intermediate members. Good. At this time, the plurality of intermediate members can be made to have the same shape, and the uppermost member and the lowermost member can be made to have the same shape. Further, when laying the fence, each member of the net material may be connected by a connection pin.

[0011] By dividing the net material of the fence into three or more members, it is possible to easily perform each operation and management such as production, storage, transportation, and laying without being limited by the size of the fence. Since the shape of each member constituting the net material can be reduced, deformation of the net material due to its own weight can be prevented. Also, even if the division of the net material is four or more, the members of the intermediate portion and the uppermost and lowermost members have the same shape, and the shape pattern of each member constituting the net material is two or three. It can be only a shape pattern,
An increase in manufacturing cost can be prevented. Further, since each member of the net material is connected by the connection pin, the design can be improved without being complicated in shape.
