[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mesh fence surrounding a site or the like, and in particular, a bent portion is formed at both ends or one end of the fence to eliminate the need for a conventional fence post.

[0002]

[Prior art]

 Conventionally, mesh fences have been constructed by burying concrete or steel pipe foundations in the ground at regular intervals along the construction range, and then steel columns are erected on the foundation and concrete is poured into the enclosure to fix it. After that, a steel frame with an L-shaped cross-section called a furrow was passed between the stanchions to form a rectangular frame both above and below, and wire mesh was stretched over this frame to build a mesh fence at the construction site.

[0003]

[Problems to be solved by the device]

 Therefore, when attempting to construct a conventional mesh fence, a member called a frame frame for tensioning a wire mesh and a plurality of members having different shapes and standards such as a pillar are required. It was necessary to select metal members with greater strength. Therefore, it takes a considerable amount of time to assemble a fence in which a plurality of these members are combined, and in order to reduce the number of assembling steps, a fence having a simple structure using a single member has been desired. In view of this, the present invention aims to provide a mesh fence that does not require a pillar by providing convex bent portions at both ends or near one end of the mesh fence.

[0004]

[Means for Solving the Problems]

 Therefore, in order to achieve this purpose, in a grid fence in which thin metal rods are welded in a grid shape to form a rectangle and stand upright on the ground surface, at least one end of the fence has a convex horizontal cross section. A support metal fitting, which is formed on the bent part and fixes the fence to the ground side, is bent corresponding to the cross section of the bent part of the fence, and the lower end of the fence is connected and fixed to the support metal so that the fence can be erected. In addition, at the connecting parts of adjacent fences, the thin metal rods in the vertical direction of both fences were connected by connecting parts.

[0005]

[Action]

 The fence of the present invention is made by combining metal rods in a grid pattern and fixing the intersecting portions of the rods by welding, so that it can be made as a mesh-like fence with no bending and having a strong rigidity. Frame materials such as columns and furring strips can be omitted. In addition, since at least one end of the fence is formed into a bent portion with a convex horizontal cross section, that portion acts as a pillar and it is easy to stand up, that is, the fence itself does not easily fall even without the pillar. ing. In addition, these fences can be connected over a long range without columns by connecting the ends with connecting members. Furthermore, by fixing the bent portion of the fence, which plays the role of a pillar, to the surface of the base with the support fitting, the fence can be erected stably on the ground surface.

【Example】

 This embodiment will be described with reference to the drawings. The fence 1 is made by crossing metal rods having two kinds of wire lengths cut according to the desired height and length of the fence 1 in a grid pattern at a predetermined interval, and welding the crossing part a by welding. It is fixedly built. The mesh of the fence surface can be manufactured with various fineness by adjusting the width of the combination of rods. Just before the end of the fence 1, the horizontal cross section of the fence is bent into a convex shape, that is, a V-shaped cross section, and the tip 1a of this ∧-shaped bent portion 2 is further extended to the end of the fence 1 by a small section. It's flat. Further, the size of the base of the ∧-shaped bent portion 2 is set to be equal to the distance a between one lattice in this embodiment, and the rising portion 2a and the apex portion 2b of the ∧-shaped bent portion 2 are set. The vertical members 3 that form the grid are always inserted. On the other hand, the connection between the fences should be made so that the vertical bending part 2 of the fence 1 and the flat end of the other fence 1A where there is no ∧ bending part 2 overlap the vertical members 3 of both fences 1 and 1A. They can be joined together and connected by the connecting member 4. When connecting the fences 1 and 1A with the same direction of the ∧-shaped bent portion 2 as shown in FIG. 1 (a), and with the fence 1 as shown in FIG. 1 (b). And the case where the ∧-shaped bent portion 2 of 1A is connected so that the positions thereof are opposite to each other.

The connecting member 4 is a substantially rectangular flat plate made of metal, and one through hole for a bolt is formed on each of the left and right sides of the plate member. Further, on the back surface of the connecting member 4, two concave grooves 4a matching the curved surface of the vertical member 3 are provided in the middle of the holes for the two bolts at regular intervals. The distance between the grooves 4a is set so as to match the distance between the two vertical members 3 when the two fences 1 and 1A are overlapped. In this way, the end having the ∧-shaped bent portion 2 of the fence 1 and the flat end of the other fence 1A are overlapped, and both vertical members 3 are overlapped with each other to form a concave shape on the back surface of the connecting member 4 from both left and right sides. The vertical member 3 is applied so as to fit in the groove 4a, and can be sandwiched by the two connecting members 4. Further, bolts 4b are passed through the left and right holes of the connecting member 4 and fixed by nuts. In this embodiment, the two connecting members 4 are provided above and below the vertical member 3 to connect them, but the number of the connecting members 4 may be changed appropriately according to the height of the fence. Therefore, by successively overlapping the end of the fence with the ∧-shaped bent portion 2 and the flat portion of another fence and connecting them with the connecting member 4, it is possible to circulate the enclosure to an arbitrary length. It has become. On the other hand, the base 5 used when the fence 1 is set up on the ground surface is made of a concrete triangular prism whose cross section is a triangle larger than the ∧ shape in accordance with the ∧-shaped bent portion 2 of the fence. The bottom of the base 5 is buried in the ground so that it does not shake. In addition, at the center of the end face of the triangular prism of the base 5 that is exposed on the ground surface, bend it according to the ∧-shaped bent portion 2 of the fence, and bolt holes at both ends of the left and right flat parts of the ∧-shaped bent portion. The lower half of the width of the wide support fitting 6A provided with is fixed to the base in an embedded manner.

Further, the support metal fitting 6B has holes for bolts set at the same intervals as the hole positions of the support metal fitting 6A at both ends of a substantially rectangular metal plate, and is provided between the support metal fitting 6A and the support metal fitting 6A. The fence 1 and the fence 1A can be fixed by sandwiching the connecting portion between them. That is, the bottom convex surface of the ∧-shaped bent portion 2 at the connecting portion of the two fences 1 and 1A described above is aligned with the ∧-shaped portion of the support metal fitting 6A of the base 5, and further the support metal fitting 6B is applied from the bottom of the back surface to form the ∧-shape. Insert the bottom of the overlapping part of the two fences between the support metal fittings 6A and 6B, and tighten the support metal fittings 6A and 6B with bolts and nuts from the left and right holes to fix the fences 1 and 1A to the base 5. It is becoming like this.

Further, in this embodiment, the convex bent portion has a ∧ shape. However, the shape may take various shapes such as a semicircle as long as it can function as a supporting column. Further, in this embodiment, the ∧-shaped bent portion is provided at one end of the fence, but it may be provided at both ends. The flat portions may be connected to each other, and various combination methods may be used as necessary. In addition, two concave grooves 4a of the connecting member 4 are provided adjacent to each other, the ends of the two connecting members 4 are aligned side by side without overlapping the two connecting fences 1, and the two vertical members 3 arranged side by side are connected to each other. The members 4 may be connected laterally. By providing the ∧-shaped bent part of the fence at the left and right center parts of the fence, the left and right balance may be maintained even if this bent part is fixed to the base, and the construction work may be facilitated in a stable state.

[Effect of device]

 Since the fence of the present invention is provided with a convex bent portion, it is more likely to stand and is less likely to fall than a conventional fence. Also, frame members such as stanchions, which were required in conventional fences, are no longer required, and the number of man-hours for installing fences on the site can be greatly reduced, and great labor savings can be achieved. Further, in terms of manufacturing, in the past, separate furring strips, struts, wire netting, etc. were manufactured in separate processes, but in the present invention, strong thick rods are mainly welded in a grid pattern. Since the fence is formed in the manufacturing process, the manufacturing process can be simplified and significant improvement in manufacturing cost can be expected.
