Description

[Detailed description of the invention] This invention relates to a protective fence made of lightweight materials that is installed at the edge of a road that also serves as a pedestrian walkway.In order to ensure the safety of pedestrians, a handrail for pedestrians is attached to the top of the protective fence. This invention relates to a protective fence that can be used as both a vehicle and a walkway and has a handrail that increases the height of the entire protective fence.

Conventionally, there was no distinction between roadways and sidewalks, and the height of protective fences installed at the edges of dual-use roads was adjusted to the height of the top rail to match the height of the tires of large trucks, etc., as shown in Figure 1. It was decided that

However, from the viewpoint of pedestrian safety, the height was insufficient, and there was a risk that the fence would fall and fall off or climb over the protective fence.

Therefore, methods have been adopted such as increasing the height of the protective fence or installing a wire mesh fence separate from the protective fence close to it, but these methods result in a larger overall size and a significant increase in installation man-hours. However, there were disadvantages such as complicated manufacturing and installation, increased weight, and difficulty in transportation.

In addition, a structure in which a wire mesh fence or the like is installed separately from the protective fence has a poor appearance, and improvements in design have been desired.

This idea was made in order to improve the above-mentioned conventional drawbacks, and it can be easily installed on existing security fences made of extruded materials such as aluminum alloy. To provide a protective fence with a handrail for use as a pedestrian walkway, which is lightweight, inexpensive, and has an excellent effect in terms of design, with a handrail for pedestrians attached to the upper part.

Hereinafter, embodiments of this invention will be explained in detail with reference to FIGS. 2 to 8.

FIG. 2 is a front view showing one embodiment of this invention, in which 1 is a post of a protective fence, 2 is a top rail, 3 is a bottom rail, 4 is a bridge, and 5 is a top rail 2 and a bottom rail 3.
It is a vertical lattice called tachiko, which is arranged in large numbers at predetermined intervals between the upper and lower sides.

Reference numeral 6 denotes handrail posts fixed to the top of the top rail 2 at intervals of the supports 1, and a handrail rail 7 is fixed to the top of the handrail post 6.

The pillar 1 is buried in concrete or the like at the edge of the road.

3 is a sectional view taken along the line A-A in FIG. 2, FIG. 4 is a vertical sectional view of the main part of FIG. 2, and FIG. The support 1 with the anchor fitting 8 fitted in the upper part in advance is fitted through the mounting hole 2a formed at the bottom of the holder, and is bolted through the bracket 9a.
Further, the column 1, the bottom rail 3, and the cross beam 4 are bolted together via brackets 9b and 9c.

Further, the top rails 2 are joined in the longitudinal direction via a connecting sleeve 10.

On the other hand, at the top of the top rail 2, an anchor fitting 8 fixed to the column 1 and a handrail post 6 made of a hollow profile are bolted at the bottom, and a handrail rail 7 is connected to the top of the handrail post 6. sleeve 11 and bracket 1
2, a photo from the hollow part of the handrail post 6 is fixed to the nut plate 11' in the sleeve 11 by screwing it to the nut plate 11',
The handrail rail 7 is attached to the upper part of the guard fence to form a height that maintains the safety of pedestrians.

That is, the protective fence with handrails that can be used as a pedestrian walkway for cars according to this invention has a support post 1, a top rail 2, a bottom rail 3, a cross beam 4,
Whether a protective fence consisting of vertical grids 5, etc. is newly installed or an existing one,
By fixing the handrail post 6 to the top rail 2 of the protective fence and attaching a predetermined handrail rail 7 to the top of the handrail post 6, the handrail for pedestrian safety can be constructed at a desired height. It is something that can be done.

As shown in the sectional view of FIG. 6, the handrail post 6 is a hollow body extruded from a lightweight profile material, so it can be easily attached to the top rail 2 of the protective fence by bolting.

Therefore, if the top rail 2 of the protective fence is thick, the mounting position of the handrail post 6 is not necessarily limited to the support post 1, but as shown in FIG.
The position can be set.

Figure 8 shows an example of the application of this invention.This invention was devised to increase the height of the protective fence for roadways on flat land to the height necessary for pedestrian safety, but This also applies to dual-purpose use, and it is installed as shown in Figure 8.

At this time, the handrail post 6' can be easily attached if the extruded material is formed at an angle along the inclined surface.

It is also possible to achieve a design effect by using a handrail post 6'' as shown in FIG. 9.

As explained in detail above, the protective fence with handrail according to this invention has a handrail rail for pedestrians attached to the top of the protective fence for roadways, regardless of whether it is a new or existing protective fence, and is made of aluminum alloy. It can be installed on all protective fences made of molded materials.

In addition, the handrail rail and the handrail post that fixes the handrail rail are made of extruded hollow material, so they are lightweight and easy to handle, and do not reduce the supporting capacity of the protective fence. There is no need to worry about strength.

In addition, the present invention is designed to simply raise the height of the handrail for the roadway (by simply replacing the short pillars and balusters for the roadway with longer ones for the sidewalk), and to protect the handrail and protection. Since the fence and fence parts are constructed separately, they can be constructed to suit the different specified loads of crowds and vehicles, so, for example, it is possible to avoid making the handrail posts thicker than necessary or using materials with higher rigidity than necessary. It is public and economical because there will be no more problems.

In addition, it is easy to install on-site and has good workability, regardless of whether the protective fence is newly installed or an existing one.It not only maintains the safety of pedestrians but also can be easily used on sloped areas, and is inexpensive and aesthetically pleasing. It has effects such as having beauty.
