At right angles to the direction of the extension line, the plate-shaped column main body 1 is attached and integrated with a multi-functional column 3 (fence column) at the edge 12 opposite to the road by a through bolt here. Standing at appropriate intervals along the road,
Beam support 13 provided on the edge 11 facing the road
Is fixed to the beam 2. Here, the plastic fence panel 43 is covered with an aluminum frame with rubber packing around the periphery thereof, and the frame is bent into a curved shape corresponding to the curve of the multifunctional column 3 and fixed to the frame via a joint 40. And is attached to the multifunctional column 3.

The cross-sectional shape of the multifunctional column 3 is generally made of a steel pipe having a circular or square cross section.
FIG. 4 shows an example of each embodiment of the plate-like column main body 1 attached to and integrated with the various multifunctional columns 3 in some forms. (A): Example of the embodiment of FIG. 1; (b): Example of the embodiment of FIG. 3; (c): H-shaped multifunctional support for a soundproof (sound insulation) wall 7 shows an example of the embodiment of the third embodiment. In each case, the wire mesh fence panel 4 is installed in exactly the same way as when it is used as a normal fence without a protective fence.
1, a vertical lattice fence panel 42, a plastic fence panel 43, etc. are installed. FIG. 4
In the case of (c), in order to develop applications for sound insulation and sound absorption effects,
A type in which a surface material is inserted by a standard assembling method of a functional surface material 44 such as sound insulation and sound absorption is applied independently of the plate-like column main body 1 which functions as a protective fence.

Next, the collision safety required for the plate-shaped column main body 1 as a column for a protective fence especially when used in a vehicle-protected fence will be described in detail. When designing beam-type protective fences for bridges, etc., it is necessary to individually demonstrate the securing of safety standards based on on-site inspections based on the “standards for the installation of protective fences” in the guideline issued by the Chief of the Road Bureau of the Ministry of Construction. About 1. 1. In addition to “normal strength performance” A performance for absorbing the impact absorption at the time of vehicle collision by a predetermined deformation amount ”is required.
(A) If the cross section indicated by the dashed line is provided with a weak portion along a predetermined standard and designed to satisfy a predetermined required performance, the above-mentioned safety standard is also applied to the multifunctional pillar-integrated protective fence of the present invention. A buckling inducing portion 14 is formed in the lower portion of the plate-like column main body 1, and the multi-functional column 3 is taken in opposition to the buckling inducing portion 14 in FIG. The buckling inducing portion 31 may be partially cut away or deformed in the attaching portion, or the buckling inducing portion 31 may be cut or deformed as shown in FIG. The multifunctional column 3 may be attached to the height portion, and may serve as the lower end of the multifunctional column 3 there.

In the above, the support for the fence 4 to which the fence panel is detachably attached via the joint 40 as the multi-function support 3 has been described in detail. FIG. 6 showing a side view of each example
(A) to (c). FIG. 5A: A sign pole is also provided. FIG. 4B shows a case where a curve mirror is provided at a curve point. FIG. 2C shows an example in which the outer diameter of the lighting post is set to match the outer diameter of the fence post, and the fence and the lighting post are installed together.

Next, the construction order of the multifunctional pillar-integrated protective fence of the present invention will be described. First, the plate-shaped column main body 1 is erected at predetermined intervals along the road. That is, an anchor bolt is implanted at a predetermined position on the road, and the base plate 16 of the plate-like column main body 1 is fixed. Next, after the beam (horizontal bar) 2 is fixed to the beam support 13, the fence 4 may be fixed to the multifunctional support 3 via the joint 40.

[0027]

As described in detail above, the multi-functional pillar-integrated protective fence of the present invention has a plate-shaped pillar main body standing upright at appropriate intervals along the road perpendicular to the direction of the road extension.
The beam is fixed to the beam support portion provided on the edge of the plate-shaped support body facing the road to form a protective fence, and the edge of the plate-shaped support body opposite to the road from the plate-shaped support body is A multi-functional support that protrudes upward is attached,
By erection of the plate-shaped support body at a predetermined position on the road, the multifunctional support is also erected integrally, and there is no need to fix the multifunctional support to the protective fence support after the protection fence support is erected as in the past. The work at the time of construction is easy.

Further, the multifunctional column-integrated protective fence according to the present invention is characterized in that the front plate is attached to the edge of the plate-shaped column main body facing the road so as to be orthogonal to the plate-shaped column main body, and is integrated with the plate. As the strength of the pillar-shaped main body increases, fixing portions such as nuts fixed to the anchor bolts are hidden behind the front plate, so that they are not directly visible and are excellent in view.

[0029] The multifunctional pillar-integrated protective fence of the present invention, when a fence panel is detachably attached between adjacent multifunctional pillars, is provided with a fence at a predetermined position of a multifunctional pillar that has been erected in advance. Since it can be attached and the fence panel is independently detachable with respect to the support column through a joint or the like, the workability is good and replacement at the time of breakage or the like is easy.

Further, the multifunctional pillar-integrated protective fence according to the present invention is used as a multifunctional pillar for road incidental equipment such as road signs, road reflectors, lighting, traffic signal equipment, traffic volume sensors, weather sensors, and communication equipment. When the equipment is supported, compared to the case where each equipment and equipment is constructed individually,
When there is no waste in the construction and the installation is performed in combination with the fence support, reasonable construction can be performed, and from the standpoint of landscape preservation, it is possible to avoid the adverse effects such as the support columns being overburdened. It will be simple and look good.

Furthermore, in the multifunctional column-integrated protective fence of the present invention, a buckling inducing portion is formed at a lower portion of the plate-shaped column main body, and a seating portion of the multifunctional column facing the buckling inducing portion is also provided. In the case where the bending and attracting portion is formed, in the unlikely event that a vehicle such as an automobile collides, the multifunctional strut is also deformed as predetermined with the deformation of the plate-shaped strut main body, so that the impact given to the car is reduced, as much as possible This is preferable because the safety of the vehicle is ensured and the injury of the occupant is reduced.
