JPS6011137Y2 - Intermediate terminal support for guard cable - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an embedded intermediate terminal support for guard cables that is easy to install and repair.

Guard cables, which are cables connected to pillars, are installed on roads to prevent car accidents and to separate roads from sidewalks.

Since the conventional guard cable has a fixed support, the following problems have been pointed out.

1. Because the pillars are fixed, if the road surface is raised, the height of the guard cables from the ground will be lower after the raising work is completed, and the guard cables and pillars will have to be reinstalled.

2. Damage to guard cables and supports during snow removal due to car collisions or snow removal vehicles in snow removal areas;
After the snow melts, complicated repairs must be made.

3. When constructing the road, it is necessary to install the pillars at the same time, so the construction period will take a long time.

The present invention solves these problems, and its configuration will be explained below.

A burying sleeve is provided on the road, in which a pair of tubes are connected at an interval, and the ends of the guard cable are connected at the upper part of the connecting waist at a distance such that the lower part can be freely inserted into the burying sleeve.
It consists of a pair of supports.

Next, an embodiment of the present invention will be described based on FIGS. 1 to 3.

Reference numeral 1 denotes an embedding sleeve made by connecting a pair of cylinders, the upper part of which is open, and a flange 1a is attached thereto.

Note that 1b is a connecting member that connects the embedding sleeves 1 at intervals.

The buried sleeve 1 is a concrete block b of a road a.
buried in

Reference numeral 2.3 designates a pair of pillars whose lower portions can be freely embedded in the embedding sleeve 1, and flanges 2a and 3a are attached approximately to the middle of the pillars so as to be able to be fixedly attached to the flange 1a.

2b and 3b are holes provided at the top of the supports 2 and 3, through which the terminal rod 5 to which the guard cable 4 is connected penetrates, and the nut 4a
It is fixed with etc.

Reference numeral 6 denotes a connecting member that connects the columns 2 and 3 at an interval.The connecting member 6a is inserted into the holes 2c and 3c provided in the heads of the columns 2 and 3, and is screwed into the female thread 6b of the connecting member 6. te, pillar 2,
3 are connected in parallel at intervals.

Figure 4 shows the case where road a is raised.
In the case of elevation work, the connecting member 6 is separated,
After loosening the guard cable 4 and pulling out the struts 2.3, install the short cylindrical auxiliary sleeve 7 on the flange 1a of the burial sleeve 1, insert the struts 2 and 3 again, and then use the connecting member 6 to separate them. The guard cable 4 is tensioned.

Therefore, the sleeve 1 for burial is placed in the concrete block 6.
After inserting the struts 2 and 3 into the sleeves lc and ld, and then fixing the struts 2.3 at intervals with the connecting members 6, the terminal rods 5 of the guard cable 4 are inserted into the sleeves lc and ld, respectively.
, 3, and is used by applying tension to the guard cable 4.

When the pillars 2 and 3 are damaged due to a car collision, etc., the guard cable 4 is loosened, the connecting member 6 is removed, and the pillars 2 and 3 are taken out to be repaired or replaced.

As such, the present invention has the following features.

■ When raising a road, all you have to do is pull out the supports 2 and 3, attach the auxiliary sleeve 7 to the top of the burying sleeve 1, and then insert the lower part of the supports 2 and 3 again. Be rational without saying anything.

2. If one of the supports 2 and 3 is damaged, it is only necessary to pull out the damaged support and replace it, which shortens the repair work and completes the work quickly.

3 Since the columns 2 and 3 are held by the connecting member 6,
A larger tension can be applied to the guard cable 4 than in the conventional single guard cable, and a safer guard cable is provided.
