Description

[Detailed explanation of the invention] [Industrial application field] This invention is used for protective fence posts installed on road dividers or roadside, for example, and in particular, to prevent the support from sinking by interposing it between the bracket and the ground. This relates to a subsidence prevention device.

[Conventional technology]

Figures 9 and 10 show the conventional subsidence prevention device disclosed in Japanese Utility Model Application Publication No. 13431/1983.
FIG. 9 is a side view, and FIG. 10 is a plan view. In these figures, 1 and 2 are grasping plates, and the grasping plates 1 and 2 form a gutter shape, and semicircular road surface plates 3 and 4 are connected horizontally to form a disk at the bottom. It is set up. The grasping plates 1 and 2 are attached to the outer periphery of the protective fence support post 5 by tightening bolts 6 and 7 in sliding contact with and facing each other.

The conventional subsidence preventive device is constructed as described above. For example, even when a load is applied to the column 5, the subsidence preventive device does not attach the bolts 6,
7, the load is supported by the road surface plates 3 and 4, and the support column 5 does not sink into the ground.

[Problem that the invention attempts to solve]

However, since the conventional subsidence prevention device is attached to the column 5 by the frictional force between the gripping plates 1, 2 and the column 5 by tightening the bolts 6, 7, for example, in a snowy area where a large snow load is applied, the column 5 If a load greater than this frictional force is applied, the gripping plate 1,
There was a drawback that the support 5 would slip between the support 2 and the support 5, and the support 5 would sink into the ground, rendering the sinking preventive device useless.

[Means for solving problems]

This invention was made for the purpose of improving such drawbacks, and includes a support member installed along the pillar of a protective fence support, a first overhang member attached under the support member, and a first overhang member attached to the support member. A subsidence prevention device was constructed with the second overhanging member attached to the top.

[Effect]

If the subsidence prevention device configured as described above is interposed between the bracket of the protective fence post and the ground, even if a large load is applied to the protective fence post, all of the load will be transferred to the second paper lining member. Since it will be added to the first overhanging member via the support member and will not be added to the pillar, the pillar will not sink into the ground.

〔Example〕

FIGS. 1 and 2 show an example of the subsidence prevention device according to this invention, with FIG. 1 being a side view and FIG. 2 being a plan view. In the figure, 8 and 9 are a pair of support members installed along the pillar 5 of the support for the protective fence.The support members 8 and 9 are made of steel with an L-shaped cross section, but the shape of the support members 8 and 9 is It is not necessarily limited to this, but may have a C-shaped cross section as shown in FIG. 6, or may have a U-shaped cross section or any other shape as long as it can be provided along the pillar 5.

For example, first overhang plates 10 and 11 are attached to the lower portions of the support members 8 and 9 as first overhang members, respectively. Although the first overhanging plates 10 and 11 form fan-shaped plate bodies, the shape of the first overhanging plates 10 and 11 is not necessarily limited to this, and may be as shown in FIG. It can be circular, or semicircular,
It may be rectangular or any other shape as long as it can disperse the load. At the corners of the supporting members 8, 9 and the first overhanging plates 10, 11, there are first overhanging plates 10, 1.
A reinforcing member 12 is attached to each of the parts to prevent deformation of the parts.

For example, second projecting plates 13 and 14 are attached to the upper portions of the support members 8 and 9 as second projecting portions, respectively. Although the second overhanging plates 13 and 14 form fan-shaped plates, the shape of the second overhanging plates 13 and 14 is not necessarily limited to this, and may be as shown in FIG. It may be rectangular, circular, semicircular, or any other shape as long as it can disperse the load. As shown in FIG. 5, reinforcing members 15 can also be attached to the corners of the supporting members 8, 9 and the second overhanging plates 13, 14.

Mounting fittings 16 and 17 for attaching the support members 8 and 9 to the pillar 5 are integrally attached to the upper and lower sides of the support members 8 and 9. The support members 8 and 9 are attached to the pillar 5 with mounting brackets 16 and 17 using bolts and nuts 18. Here, the support members 8, 9 and the mounting brackets 16, 17 are constructed as separate pieces, but as shown in FIG.
may also be used as a support member. In addition, the one in FIG.
14 is installed, but as shown in Figure 3,
The upper mounting bracket 17 may also be used as the second projecting member.

When the subsidence preventive device configured as described above is attached to the protective fence post as shown in FIG. 7 or 8, the load of the bracket 19 is transferred to the second overhang plate 1.
3, 14, support members 8, 9 and first overhang plate 10,
The load of the bracket 19 is applied to the ground via the bracket 11, and the load of the bracket 19 is not applied to the column 5.

[Effect of idea]

As explained above, this idea has the effect of being able to prevent the protective fence posts from sinking even when a large load is applied to them, due to the simple structure of providing overhanging members at the upper and lower parts of the support members. .
