Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a combination of road equipment having support columns and guard cables.

It is well known that guard cables are installed on road shoulders to ensure road safety.

Conventionally, in many locations where guard cables are installed, road equipment with supporting pillars, such as columnators (light reflecting devices) and various signs, have also been installed, and these road equipment are tied to the guard cable pillars with attachment bands or attached to the guard cable. It is placed in line with the cable support.

The installation of such guard cables and road equipment has drawbacks such as being uneconomical, sometimes requiring wasteful installation space, being troublesome to maintain, and detracting from the aesthetics.

This invention aims to eliminate such conventional drawbacks.

In order to achieve this object, according to this invention, the guard cable is constituted by a guard cable having a support column of a tubular body with an open upper end, and a road equipment having a support column body inserted into the tubular body, A fixture having a guide member at the lower end that projects laterally until the body sufficiently approaches the inner wall of the tubular body, and a fixture having an inclined side surface in the form of an inverted conical surface is fixedly attached to the intermediate portion of the support columnar body. There is provided a combination of road equipment and guard cable having a strut-like body, characterized in that the fixing device is driven into the open upper end of the tubular body from above.

According to the combination of this invention, the pillars of the guard cable and the support pillars of the road equipment are combined, so it is highly economical, there is no need to secure installation ground for the road equipment, and maintenance is reduced. Moreover, the arrangement of the guard cable supports and the support pillars of the road equipment can be avoided, so that the aesthetic appearance is not spoiled.

This invention further has the advantage that the existing guard cable can be used as is, since it can be achieved by using an existing guard cable, removing the cap of the support column, and attaching the support column for the road equipment to the support column.

This invention will be described in detail below with reference to the drawings.

The guard cable 1 has a number of wires 2 running parallel to the ground and spaced apart from each other above and below, as shown in FIG. In the intermediate position, the wire 2 is supported by the intermediate strut 3 of the guard cable, and in the terminal position, it is tension-supported by the terminal strut 5 of the guard cable via a tension bolt 4 connected to the end of this wire by a fastener. .

Each strut 3,5 is formed as a tubular body as shown in FIGS. 2, 4 and 5, with a cap 6 usually placed over the upper end of the tubular strut 3.5 as shown in FIG. It will be done.

At the intermediate strut 3, the wire 2 is attached to a support fitting 7 as shown in FIGS. 2, 3 and 4.

In the conventional structure, the support bracket 7 is attached to the intermediate support 3 by a through bolt 8 (Fig. 2), but in this invention, the through bolt is removed and a short individual bolt 9 is installed in the hole for the purpose described later. Attached to post 3 (
Figure 4).

As shown in FIG. 5, the tension bolt 4 passes through the terminal column 5 and is attached to this column.

Delineators 10, 10a attached to columns 3, 5 according to this invention are illustrated in FIGS. 1, 6, and 7 (in these figures, the shape and structure of the delineators are illustrated as being slightly different for convenience), Support columnar body 11,1
12 and a delineator body 12, 12a supported by and integral with the delineator body 12, 12a.

In the delineator 10 attached to the intermediate strut 3, as shown in FIG. It has a fixture 15 having an inclined side surface 14 in the form of an inverted truncated cone.

The stabilizing vane 13 is sufficiently close to the inner wall of the tubular intermediate strut 3 and has dimensions and shapes such that it can be fitted without difficulty into this intermediate strut with short individual bolts 9, and is fitted with a fixing device 15.
is sized and shaped so that it can be secured to the upper end of the tubular intermediate column with its sloping side surface 14.

When installing such a delineator 10 on the intermediate support 3, the cap 6 (third
(Fig. 4), replace the through bolt 8 (Fig. 2) of the intermediate column 3 with a short single bolt 9 (Fig. 4), and then lower the lower part of the support column 11 of the delineator 10 to the position shown in Fig. 6. Insert into the intermediate support 3 and drive the fixture 15 downward.

By this driving, the inclined side surface 14 of the fixture 15 is strongly held against the upper end of the tubular intermediate column 3, and the delineator 10 is fixedly attached directly to the intermediate column 3.

The stabilizing vane 13 serves as a guide during the insertion of the lower part of the support column 11 into the intermediate strut 3 and prevents tilting of the columnar 10 in the installed position.

As shown in FIG. 5, the tension bolt 4 passes through the terminal strut 5, so it is not possible to attach a delineator in the same manner as in the case of the Okima strut 3.

In the case of this terminal support 5, from this support 5 to the cap 6
(Figure 3) After removing the delineator 10a, a split groove 16 is formed at the lower end as shown in Figures 7 and 8.
The lower part of the support columnar body 11a is fitted into the upper part of the tubular terminal support column 5, the fixing sleeve 17 is placed around this fitted part, and then the taper key 18 is driven in to terminate the delineator support columnar body 11a. It is fixedly attached to the pillar 5.

Delineator 10, 10 a to guard cable 1 support post 3
．． 5 is shown in FIG.
