Description

[Detailed description of the invention] <<Industrial application field>> This invention relates to a fence in which a tensioning body such as wire mesh or expanded metal is stretched. This relates to fences that prevent

《Prior art》 For fences that have a structure in which horizontal beams installed vertically opposite each other are supported by pillars that are erected and fixed on foundations buried in the ground, it is necessary to install a foundation on which the pillars are erected and fixed. Because construction costs are high and labor is required, the spacing between the pillars is widened as much as possible.

However, as time passes and in snowy regions, due to the weight of snow that has accumulated (snowed) on the horizontal beams and tensioning bodies, the supports alone cannot support the horizontal beams and the tensioning bodies, and the middle part of the pillars may sag. It happens.

In order to prevent this sagging, conventional methods have been to install reinforcing bars between the upper and lower horizontal bars between the columns (for example, Utility Model Publication No. 56-15964), or to provide reinforcement bars between the lower horizontal bars between the columns and the ground. There are some with pillars (for example, Utility Model Application No. 58-3569).

《Problems to be solved by the invention》 Among the conventional sagging prevention fences, those with reinforcing bars installed between the upper and lower horizontal bars work to reinforce the stretched structure, but the upper and lower horizontal bars do not support the load. If this is not possible, the problem remains that both the upper and lower horizontal bars may sag in the center between the columns.

Furthermore, in the case where the lower horizontal beam is supported by auxiliary columns, the upper horizontal beam is supported only by the pillars as in the past, so the upper horizontal beam and the tensioning body will sag when they cannot withstand the load.

Therefore, an object of the present invention is to provide a fence that can be easily constructed and prevents the horizontal crosspieces between the columns and the hanging bodies from sagging.

《Means for solving the problem》 The present invention is based on the horizontal beams 3 installed vertically facing each other.
a, in a fence in which the tension body 4 stretched between the crosspiece 3b and the horizontal crosspieces 3a and 3b is supported by the supports 2 erected and fixed on the foundation 1 buried in the ground, the supports 2, 2
The auxiliary support 5 arranged between the upper and lower horizontal crosspieces 3a and 3b is fixed in contact with the tension body 4 stretched between the upper and lower horizontal crosspieces 3b, and the lower part 6 of the auxiliary support 5 abuts against the lower horizontal crosspiece 3b and is bent. In addition, the lower end hangs down directly below the tension body 4 and is connected and supported to a bottom metal fitting 7 placed on the ground.

<<Function>> Next, the function of the present invention will be explained. The auxiliary column 5 is located between the columns 2, 2, and the upper horizontal bar 3a and the lower horizontal bar 3.
Since it is abutted and fixed to the tension member between b, it acts as a support, supporting the tension member and keeping the distance between both horizontal bars constant.

The lower part 6 of the auxiliary support 5 is bent by contacting the lower horizontal crosspiece 3b, hangs down directly below the tension body 4, and is connected and supported by the bottom metal fitting 7 placed on the ground. It also has a supporting effect of the crosspiece 3b and has sufficient supporting force, and when the upper and lower horizontal crosspieces 3a and 3b cannot withstand the load, the support effect of the auxiliary support column 5 on the tension body 4 and the lower horizontal crosspiece 3b prevents the sagging. As a result, the load on the upper horizontal bar 3a is reduced, and drooping of the upper horizontal bar 3a is also prevented.

In addition, the bottom metal fitting 7 is placed on the ground and connected to the auxiliary support 5, so that the auxiliary support 5 supports the tension body 4 and the lower horizontal crosspiece 3.
This, together with the fact that it comes into contact with b and obtains a load, performs the fixing and supporting functions of the bottom metal fitting 7.

《Example》 Figure 1 is a front view showing an example of the present invention, in which foundations 1 buried underground are constructed at regular intervals,
Upper and lower horizontal beams 3a, 3b are erected and fixed on pillars 2, 2, etc. which are erected and fixed on the foundation 1, and a tensioning body 4 such as a wire mesh is stretched between the upper and lower horizontal beams 3a, 3b and the pillars 2. .

The support column 2 and the upper and lower horizontal bars 3a, 3b are connected by appropriately known means, and the tensioning body 4 is also tensioned by using various attachments depending on the shape of the horizontal bars 3, if necessary. be.

Reference numeral 5 denotes an auxiliary support column, which is placed on the front and rear surfaces of the fence, as shown in the longitudinal cross-sectional view of Fig. 2, and its upper end is connected to the upper horizontal crosspiece 3.
a, extends between the upper and lower horizontal bars 3a and 3b, and the lower part 6 hangs down so as to be abutted and supported while bending along the circular arc surface of the lower horizontal bar 3b.
It is attached by a connecting member 11 to the bottom metal fitting 7 placed on the bottom metal fitting 7.

The bottom fitting 7 has a bottom plate 8, can be stably placed on the ground, has an upright piece 9 that is a connection part with the lower part 6 of the auxiliary support 5, and has a plurality of mounting holes drilled in the vertical direction. The auxiliary column 5 can be connected in a vertically adjustable manner.

In addition, auxiliary supports 5, 5 placed on the front and rear surfaces of the fence
are fixed to each other with the connecting member 11, and the tension body 4 and the lower horizontal beam 3b are clamped and integrated.

Figure 3 shows a case in which the auxiliary column 5 that is in contact with the fence is in contact with only one side, and the other side is clamped with a reinforcing plate 13, and Figure 4 shows a case in which the auxiliary column 5 is in contact with only one side. The tension member 4 is integrated with the direct connection member 11.

In Fig. 5, the connecting part of the lower part 6 of the auxiliary support 5 with the bottom metal fitting 7 is a screw rod 6a, which is inserted into the upright piece 9 of the bottom metal fitting 7 and connected at an appropriate position with adjustment nuts 12, 12 screwed to the screw rod 6a. It is fixed.

Figure 6 shows an example in which the auxiliary struts 5 that come into contact with the front and rear surfaces of the fence are integrated at the upper end, and Figures 7 to 10 show an embodiment in which the auxiliary struts 5 are provided on an L-shaped horizontal beam. It shows.

<<Effect of the invention>> As described above, the present invention provides the auxiliary support 5 between the supports 2, 2, and indirectly holds the lower horizontal crosspiece 3b, the tension body 4, and the upper horizontal crosspiece 3a. The upper and lower horizontal beams 3
This has the effect of preventing hanging of the tension members a, 3b and the tension member 4.

Since the auxiliary strut 5 comes into contact with and supports the lower horizontal beam 3b, it has the effect of increasing the fence supporting force of the auxiliary strut 5.

In addition, the bottom metal fitting 7 that supports the auxiliary support 5 does not require any special foundation work, just by placing it on the ground, so construction is extremely simple.
By connecting with the auxiliary support column 5, which is integrated with the net, the bottom metal fitting 7 becomes integrated with the net, which stabilizes the mounting position and has the effect of being able to sufficiently withstand downward loads.

Furthermore, by adjusting the connecting position of the auxiliary support 5 and the bottom metal fitting 7, or by replacing the bottom metal fitting, it is possible to adjust the distance between the lower horizontal beam 3 and the ground and its change.
