Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a fence suitable for construction on sloped land.

<Prior art> Among the conventional fences with cylindrical edges made of vertical wire rods and horizontal wire rods, those for sloped areas are shown in Fig. 8 a, b, c,
It was manufactured using a process similar to d.

First, as shown in Figure 8a, there is no horizontal wire in the fence main body, that is, the fence main body has two vertical wires
1 only, and the vertical wire 21 and the horizontal wire 2 are installed at the upper and lower ends.
2 is in a welded state, and then the upper and lower ends are bent into a cylindrical shape to form the cylinder edge 23 as shown in figure b, and then the cylinder is bent to match the slope of the slope as shown in figure c. After tilting only the edge 23,
The horizontal wire 24 was welded to the main body of the fence in an inclined state as shown in FIG. In this way, when manufacturing a conventional fence for sloped land, the cylindrical edge 23 is
The disadvantage was that the processing equipment for tilting was expensive.

<Purpose> Therefore, the present invention was made to eliminate the above-mentioned drawbacks of the conventional technology. By forming the fence body and the cylindrical edge separately from each other, it is possible to manufacture a fence for use on slopes at low cost. In particular, the present invention aims to provide a fence that can be fixed in combination by selecting and combining wires with different patterns, wire diameters, or wires of any strength for the fence main body and the cylindrical edge, and which has good front-to-back balance and is strong. The purpose is

<Example> Hereinafter, an example of the present invention will be described based on the drawings. First, the first embodiment will be explained with reference to FIGS. 1, 2, and 3.
and horizontal wire rods 2 are welded in a lattice shape to a fence main body A having a rectangular shape as a whole, and are fitted to the upper and lower edges (or upper edges) of the fence main body A in a substantially front-back symmetrical manner with respect to the center line Y of the vertical wire rods. A laterally long cylindrical (or prismatic) cylinder edge B consisting of a side view C-shaped ring member 3 made of a large number of wire rods and a plurality of horizontal wire rods 4 welded to the middle part of the ring member 3. It is equipped with.

First and second horizontal wire rods 2a and 2b are located at the upper and lower ends of the vertical wire rod 1 and are welded to the vertical wire rod 1 with appropriate vertical intervals, and the top and bottom ends of the cylindrical edge B. The first and second horizontal wire rods 2a, 2 are located at
The connecting members, that is, the first and second horizontal connecting wires 4a, 4b that are in direct or indirect contact with and fixing means C for fixing B and B to each other.

In Fig. 1, F1 is a fence for flat ground;
Reference numeral 2 denotes a fence for use on a slope, and its horizontal wire rod 2 is inclined along the slope. Since these fences, especially their cylindrical edges B, are firmly connected to the support columns D by the joints E, the cylindrical edges B are hardly twisted by external forces.

Further, the fixing means C includes a first horizontal wire rod 2a and a second horizontal wire rod 2b for connecting the cylindrical edge of the fence main body A.
and a metal wrap-type fastener 5 that fastens the first horizontal connecting wire 4a and the second horizontal connecting wire 4b of the cylindrical edge B in a state where they are in contact with each other.

In addition, the dimension G between the open ends 6 of the ring material 3 of the cylinder edge B (or between the horizontal connecting wires 4b and 4b) is manufactured to a dimension that allows the horizontal wires 2a and 2b of the fence main body A to pass through (as shown in the imaginary line diagram). The dimension G becomes approximately equal to the wire diameter of the vertical wire rod 1 when the fastener 5 is tightened, as shown by the solid line.

Therefore, assembly to the fence main body A is carried out at a factory or at the construction site, by fitting the cylindrical edges B shown in phantom lines into the upper and lower ends of the fence main body A, and connecting each other's wire rods 2a, 4a and wire rod 2b. , 4b are in contact with each other, a stopper 5 having an opening 7 is fitted at an appropriate pitch, and the stopper 5 is plastically deformed using an appropriate tool to be in a tightened state.

In addition, the first horizontal wire 2 of the fence body A and the cylinder edge B
The state in which a and the first horizontal connecting wire 4a and the second horizontal connecting wire 2b and the second horizontal connecting wire 4b are in contact with each other is as shown in FIG.
Alternatively, as shown in FIG. 4 showing the second embodiment, the first horizontal connecting wire 4a is in direct contact with the first horizontal connecting wire 2a, and the second horizontal connecting wire 4b is in direct contact with the first horizontal connecting wire 4b. It may be made to contact the second horizontal wire 2b indirectly via the ring member 3.

Furthermore, as in the third embodiment shown in FIG. 5, the fixing means C does not use the stopper 5, but uses a reinforcing piece 8 and a bolt/nut 9 spanning the pair of horizontal wires 4 of the cylindrical edge B.
It may be constructed so that the open end 6 of the cylinder edge B is tightened.

Next, FIGS. 6 and 7a show a fourth embodiment of the present invention, in which the cylindrical edge B is formed from a ring member 3 made of a cylinder with a through hole 10 made of iron plate, and the opening 11 The outward connecting band member 12 consisting of a narrow flange, which is a connecting member forming a , the horizontal connecting band member 12 is directly sandwiched between the second horizontal wire members 2b. That is, the upper edge of the connecting band 12 is vertically sandwiched between the first lateral wire 2a of the fence main body A and the second lateral wire 2b, and the fixing means C is the lower edge of the connecting band 12. It is pressed against the vertical wire 1 of the fence main body A by a tightening bolt/nut 13. The other configurations are the same as those of the first embodiment.

Moreover, FIG. 7b shows a fifth embodiment of the present invention,
In this case, the narrow connecting band 12 forming the opening 11 of the cylinder edge B is configured to face inward and have the same function as the horizontal connecting wire 4 of the cylinder edge B of each of the above embodiments. The upper edge of the band 12 is vertically sandwiched between the first horizontal wire 2a of the fence main body A and the second horizontal wire 2b, and the tightening bolt/nut which is the fixing means C is inserted. 13, it is pressed against the vertical wire 1 of the fence main body A.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

<Effects> As is clear from the above description, the present invention includes a rectangular fence body in which a large number of vertical wire rods and horizontal wire rods are welded together in a lattice shape, and a fence body with the vertical wire rods attached to the upper edge of the fence body. A cylindrical edge having a C-shaped cross section and long in the horizontal direction and fitted in a substantially longitudinally symmetrical manner with respect to the center line, and a cylindrical edge located at the upper end of the vertical wire and welded to the vertical wire with an appropriate vertical interval from each other. a first horizontal wire rod and a second horizontal wire rod, a connecting member provided on the tube edge so as to directly or indirectly touch the first and second horizontal wire rods in the vertical direction; It is provided with a fixing means for fixing the fence main body and the cylindrical edge to each other in a state where the wire rod and the connecting member are in contact with each other in the vertical direction.

Therefore, according to the present invention, since the fence main body and the cylindrical edge are formed separately from each other, it is possible to manufacture the fence at a low cost by keeping the cylindrical edge for slopes the same as that for flat areas, and also to make the fence main body and cylindrical edge different from each other. Wires with different patterns, wire diameters, or wires with any strength can be selected and fixed to the cylinder edge in combination. Since the fence main body and the cylindrical edge are fixed to each other in a state where the wire rod and the connecting member are in contact with each other in the vertical direction, there is an excellent effect that the front and rear balance is good and the strength is high.
