Abstract

PROBLEM TO BE SOLVED: To provide a falling object protecting fence and barrier eliminating rebound of a falling object to a road side. SOLUTION: A column 21 of a guard rail 2 installed in a sidewall 51 of the road 50 is attached with a support 11 and the support 11 is attached with a fence panel 10. The fence panel 10 is formed into an arc shape curved vertically toward the outside of the road 50 so as to be formed into a swelling part 12. The swelling part 12 eliminates the falling object hitting on a fence panel 10 from rebounding and makes it to fall to the lower side of the fence panel 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a falling object prevention fence and a falling object prevention fence.

[0002]

2. Description of the Related Art In highways and the like, guardrails are provided on the sides of roads to prevent vehicles from jumping out. There was a problem that jumping out could not be prevented with a guardrail. For this reason, in recent years, fences for preventing falling objects have been installed side by side on guardrails or provided independently on the side of an expressway. Such a fence prevents falling objects from jumping out of the road.

[0003]

However, when the fence is installed, the fence can prevent the fall from the road, but the fallen object hits the fence and bounces to the road side.
On the contrary, the problem of being dangerous is emerging. The present invention aims to solve the above problems of the prior art.

[0004]

In order to achieve the above object, the present invention is a fallen object prevention fence installed on a side portion of a road or the like, in which at least a part of a panel forming the fence is a road surface. And a bulging portion that bulges on the opposite side. The bulging portion can prevent the falling object from bouncing. As a shape of the bulging portion, generally, a curved portion is preferable. This fall prevention fence is usually used in combination with a guard rail installed on the side of a road, and it is desirable to form a fence as a whole. In this case, the fence is installed further outside the guardrail,
Falling objects are prevented, and the bulging portion bulges outward. It is desirable that the bulging portion is also a curved portion that bends outward in the vertical direction, and there is no gap between the guard rail and the fence so that a falling object can pass therethrough. It can catch fallen objects between the guardrail and fence, and has a great fall prevention effect.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, a side wall 51 is provided beside the road 50, and the guard rail 2 is formed on the side wall 51. The guard rail 2 is composed of a guard pipe 20 and a plurality of columns 21 provided at predetermined intervals. The guardrail 2 may be provided directly on the road 50 without the side wall 51. Further guardrail 2
May not be provided.

The fence 1 is installed outside the guardrail 2, that is, on the side opposite to the road 50. The fence 1 is composed of a pillar 11 attached to a pillar 21 and a fence panel 10 supported by the pillar 11.

The pillar 11 and the fence panel 10 are curved in the vertical direction to form a side arc, and a bulging portion 12 bulging to the outside of the road 50 is formed. The lower end portion 13 of the fence panel 10 is close to the column 21 and the side wall 51 so as not to form a gap through which a falling object passes.

In this embodiment, the fence panel 10 is formed of a wire lattice in which wire rods are combined vertically and horizontally and welded. However, the present invention is not limited to this. It is possible to use any shape such as a fence using.

In the above construction, when a fallen object such as a truck hits the fence panel 10, it falls in the space formed by the bulging portion 12 and falls between the bulging portion 12 and the pillar 21 to the road 50 side. There is no bounce. Therefore, it is possible to prevent troubles such as an accident of a following vehicle due to a falling object.

Another embodiment is shown in FIGS. Figure 3
The fence 1 ′ uses a fence panel 10 ′ that is bent in a triangular shape on the side surface, and the bulge 12 is formed by the bending to prevent the falling object from rebounding.

The fence 1 "in FIG. 4 is a fence panel 1
The lower part of 0 "is inclined obliquely to the outside and rises in the middle part to be vertical. This structure forms the bulging part 12.

The fence 1 "'in FIG. 5 uses a fence panel 10'" that is simply inclined outward, and the bulge 12 is formed by this inclination. As described above, the fence panel 10 can have various shapes, and if the bulging portion 12 is formed to prevent the falling object from bouncing,
The shape is not limited.

[0013]

As described above, according to the falling object prevention fence or the falling object prevention fence exposure apparatus of the present invention, the falling object does not bounce back to the road side, and the falling object is effectively ejected from the road. There is an effect that can prevent.
