  All of the fence intrusion prevention fences described in Patent Documents 1 to 3 are constructed by embedding the lower end of the fence to prevent the fence from entering the ground by digging. The steel fence or steel wire is arranged in a grid at intervals that prevent animals from passing through, so if there are few steel bars or steel wires, sufficient strength cannot be obtained, and if too much, the material is wasted. The cost is high.

  Therefore, the present invention has a simple structure, sufficient strength, can be installed at low cost, and can prevent the kite from getting over and can reliably prevent the digging in the ground. The purpose is to provide an intrusion prevention fence.

  According to the first aspect of the present invention, intersections of a plurality of longitudinal steel wires arranged at intervals in the transverse direction and a plurality of transverse steel wires arranged at intervals in the vertical direction are combined. In the fence intrusion prevention fence, which is an embedding part that embeds the lower part of the vertical steel wire protruding from the fence part in the ground with the fence part located on the ground, it is horizontal to the upper half height where the fence of the fence part does not jump over Directional steel wires are arranged at narrow intervals, and the remaining half height is arranged at wide intervals.

  The invention of claim 2 is characterized in that the longitudinal steel wire and the transverse steel wire are galvanized steel wires.

  The invention of claim 3 is that the outer diameter of the longitudinal steel wire and the transverse steel wire is 5.0 mm, the longitudinal steel wires are arranged at intervals of 245 mm in the transverse direction, and the transverse steel wire is The lower half of the fence is positioned at a distance of 60 mm from the bottom to 600 mm, and the remaining upper half is arranged at intervals of 160 mm, 170 mm, and 180 mm in order from the bottom.

  In the present invention, since the lower half of the fence part has the horizontal steel wires arranged at narrow intervals, the strength of the fence entry prevention fence can be increased and the entry of the fence can be prevented. In addition, the upper half does not need to get over the rods, so that the number of wires required for maintaining the strength of the steel wire at a wide interval is sufficient. Moreover, since the number of steel wires in the lateral direction is small, the wind pressure due to strong winds can be reduced, so that collapse can be prevented.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a unit of a fence entry prevention fence according to the present invention.

  In FIG. 1, the unit of the fence intrusion prevention fence according to the present invention includes a plurality of longitudinal steel wires 1 arranged at intervals in the horizontal direction and a plurality of transverse directions arranged at intervals in the vertical direction. The steel wire 2 is configured by being joined in a lattice shape. The unit of the heel intrusion prevention fence is formed in, for example, a rectangle having a length (height) of about 1200 mm and a width of about 2000 mm.

  A plurality (9 in FIG. 1) of steel wires 1 in the vertical direction are arranged at intervals (about 245 mm in FIG. 1) in the horizontal direction. For the steel wire 1, for example, a galvanized steel wire is used to prevent rust. The steel wire 1 has an outer diameter of about 5.0 mm and can provide sufficient strength.

  A plurality of transverse steel wires 2 are arranged at intervals in the vertical direction. The intersection F where the longitudinal steel wire 1 and the transverse steel wire 2 are in contact is joined by welding to form a lattice-shaped fence portion F located on the ground.

  The steel wires 2 in the transverse direction are arranged at a narrow interval (about 60 mm in FIG. 1) to the height of the upper half of the fence part F, and the height of the other half is a wide interval (about 160 mm, about 160 mm, in order from the bottom in FIG. 1). 170 mm, about 180 mm).

  Since the horizontal steel wires 2 are arranged at a narrow interval in the lower half of the fence portion, the horizontal steel wire 2 and the vertical steel wire 1 can be coupled at a narrow interval, so that it is necessary to maintain the strength. The strength in the lateral direction can be increased with the minimum number. Furthermore, as a result of the wide interval between the steel wires 1 in the vertical direction, the number of the steel wires 1 in the vertical direction can be reduced. Further, it is possible to prevent the wrinkles from entering between the lattices.

  Further, the upper half of the fence portion of the horizontal steel wire 2 does not get over the fence, so that the number of wires necessary for maintaining the strength of the unit with a wide interval is sufficient. Further, since the number of steel wires in the lateral direction is small, the wind pressure received by the unit due to the strong wind can be reduced. As a result, collapse due to a typhoon or the like can be prevented.

  The lower part of the vertical steel wire 1 extending from the fence part F is an embedded part buried in the ground. By embedding the embedding part in the ground, it cannot pass through even if a pit digs a hole.

  FIG. 2 is a view showing a state in which the units of the fence intrusion prevention fence according to the present invention are installed side by side.

  The unit of the fence entry prevention fence according to the present invention is manufactured in advance in a factory. Carry a unit for the fence entry prevention fence manufactured at the factory to the installation site.

  In FIG. 2, the unit of the fence intrusion prevention fence is positioned between the support posts 4 that are spaced apart from the ground, and the embedded portion 3 is embedded, and the vertical steel wire 1 is fastened to the support posts 4 with the fixtures 5. This makes it easy to install.
