Description

The present invention relates to a support structure for a support wire for a support that reinforces a support used for a wire support, a ball-proof net body, and a method for attaching the support wire for the support.

2. Description of the Related Art Conventionally, a ball-proof net body installed so as to surround an outer periphery of a ground such as an outdoor ball game facility is suspended between a plurality of pillars erected on the ground at a desired interval along the outer periphery. ing.

Between the struts on which the net body is suspended, two branch wires are alternately crossed and connected in the vertical direction of adjacent struts to reinforce the struts.

Alternatively, four branch wires are crossed and connected in two stages according to the vertical height of the net body.

Problems to be solved by the invention

However, since the above-mentioned conventional branch wire for the support column is formed by connecting two branch wires in a crossing manner in the vertical direction of the adjacent support column, a large tensile force acts in the direction of the branch wire, and the support wire is connected to the net. It can be reinforced with respect to the direction in which the body is stretched, but it cannot be sufficiently reinforced with respect to the direction intersecting the net body.

In particular, in the corner portion, the support suspended from the net body is likely to be displaced to the ground side, and it is necessary to support the support in the opposite direction.

In addition, it is necessary to consider the geology of the ground supporting the column and the strength of the underground part against the displacement of the column.

Accordingly, the present invention provides a structure for attaching a branch wire for a pillar that appropriately prevents the inclination of the pillar, is safe and does not require frequent maintenance, and a method for attaching the branch wire for the pillar. Let it be an issue.

Effects and effects of the invention

Mounting structure of the branch wire supporting columns of the present invention, and the effect of the mounting method of the branch wire for the posts will be described.

First, the support wire for a support column according to claim 1 is reinforced by connecting to a plurality of support columns standing on the ground in order to suspend the net body.

The branch wires connect the two branch wires so as to intersect each other in an up-down direction between adjacent columns in an elevational view .

At this time, between posts consuming load in the corner portion, the first branch wire is connected to the upper end side of one of the struts, the other end connected to the lower end of the other strut, the second branch wire, the other The support rod is connected to the upper end side of the support column and the branch rod rod is connected to the lower end side, and the surface on which the net body is suspended and the second branch wire form a predetermined angle on the tip end side of the branch rod rod By fixing the anchor embedded in the ground, the tension between the columns can be reduced and the inclination of the column to the front side can be reduced as compared with the case where the branch lines are crossed and connected.

In addition, since the column can be reinforced at a desired position, it is possible to optimally cope with the reinforcement of the corner portion that is particularly easily inclined inward.

Next, according to the method of attaching the support wire for the support according to the second aspect, the support is erected on the ground at a desired interval, and the net body is suspended between the support.

Thereafter, the supporting lines are reinforced by connecting two branch wires so that the vertical direction between the adjacent supporting lines intersects in an elevational view .

At this time, between the struts to which a load is applied in the corner portion , one of the first branch wires is connected to the upper end side of the strut, the other end side is connected to the lower end side of the other strut, and one of the second branch wires is After connecting to the upper end side of the other strut, connecting a branch rod rod to the lower end side and connecting an anchor to the tip end side of the branch rod rod, the anchor portion is connected to the surface on which the net body is suspended and the first The tensile direction of the second branch wire is adjusted by being embedded in the ground so as to form a predetermined angle with the two branch wires.

Thereby, since the inclination direction of a support | pillar can be pulled in the reverse direction, the frequent maintenance of a support | pillar is not required.

In addition, the strut can be reinforced at an appropriate position at all times, and the strut can be reinforced smoothly.

FIG. 4 is a schematic front view showing another embodiment of the support wire for the support column according to the present invention, and FIG. 5 is a net suspended along the outer periphery of the ground. FIG. 6 is a schematic front view showing the net body of FIG. 5, and FIG. 7 is a flowchart showing a method of attaching a branch wire for a column according to the present invention.

The support wire 1 for a support of the present invention is used by suspending a net body 10 and connecting it between support posts 11 standing on the ground.

The branch wire 1 includes a first branch wire 2 having one end connected between adjacent struts 11 to the upper side of one strut 11A and the other end connected to the lower side of the other strut 11B. The second branch wire 3 is connected to the upper side of the support 11B and the other end side is connected to an anchor 5 for fixing to the ground via a branch lot rod 4.

The second branch wire 2 embeds the anchor 5 in the ground so that the installation angle is 45 degrees to 30 degrees with respect to the vertical direction of the column 11.

As described above, a large tensile force is generated in the connecting direction of the first branch wire 2 and the second branch wire 3 in the adjacent support columns 11A and 11B. Using this tensile force, the tensile force (P) is applied in the direction perpendicular to the direction in which the second branch wire 3 is suspended to the tension of the first branch wire 2 (W), The inclination (S) due to the displacement (V) occurring in the leg portion of the column 11 is prevented.

In the above-described embodiment, the first branch wire 2 is connected to the upper end side of one support column 11A, the other end side is connected to the lower end side of the other support column 11B, and the second branch wire 3 is connected to the upper end side of the other support column 11B. The other end side is directly buried in the ground, but the attachment of the branch wire 1 of the present invention is not limited to this, for example, the first branch wire 2 is divided into two (2A, 2B), One end side of the first branch wire 2A is connected to the upper side of one column 11A, the other end side is connected to the middle part of the other column 11B, and one end side of the first branch wire 2B is connected to the other column 11B. It is connected to the middle part, the other end side is connected to the lower end side of one strut 11B, the second branch wire 3 is divided into two (3A, 3B), and one end side of the second branch wire 3A is connected to the other strut 11B. Connected to the upper end side and the other end side of one strut 11A It is also possible to connect the second branch wire 3B so that it is embedded in the ground by connecting one end side of the second branch wire 3B to the middle portion of one strut 11A and connecting the anchor 5 to the other end side. .

The branch wire 1 for a column according to the present invention is configured as described above. Next, the branch wire 1 attached to reinforce the column 11 that supports the net body 10 suspended along the outer periphery of the ground will be described.

First, a plurality of support columns 11 are erected at desired intervals along the outer periphery of the outdoor ground, and the branch wire 1 is connected between the adjacent support columns 11.

The branch wire 1 is usually connected so that two wires are alternately crossed in the vertical direction between adjacent columns 11. Thereby, although a large tensile force is generated in the attachment direction of the branch wire I, a displacement occurs in the leg portion of the column 11.

In particular, the pillars 11B and 11C in the corner portion are pulled on both sides and are subjected to a load that is inclined (S) to the ground side, and the leg portions of the pillars 11B and 11C are easily displaced (V). Although the support beam 7 is attached to the upper side, the load cannot be sufficiently eliminated.

Therefore, the branch wire 1 is connected by connecting one end of the first branch wire 2 to the upper end side of one of the columns 11B and 11C and connecting the other end to the lower end of the other column 11A and 11D. One end side of the wire 3 is connected to the upper end side of the support pillars 11A and 11D, the other end side is pulled so as to be inclined by 30 to 45 degrees with respect to the suspending direction of the net body 10, and the anchor 5 fixed to the front end side is fixed to the ground. Buried in

Thereby, displacement (V) can be eliminated by the inclination (S) of the leg portions of the columns 11B and 11C.

Moreover, each support | pillar 11A, 11B, 11C, 11D etc. can be set up with sufficient balance, and frequent maintenance is not required like the past.

Further, only the portion of the column 11 where the load is applied can be appropriately reinforced.

As described above, the support wire 1 for the support column according to the present invention can appropriately relieve the support column 11 by properly eliminating the inclination of the support column 11.

Moreover, the support | pillar 11 can be reinforced over a long period of time, and frequent maintenance is not required.
