Description

[Detailed Description of the Invention] The present invention relates to a pedestal for erecting a portable warning pole to be placed around a restricted area at a civil engineering work site such as a road or side ditch.

Conventionally, civil engineering work warning posts have been used at civil engineering construction sites, which are made of a pedestal made by pouring concrete into a mold and allowing it to harden. The base of the warning pillar is entirely made of concrete, so
Since it requires a large amount of concrete and the concrete is exposed around the entire circumference, it is easily damaged by collisions during transportation or pressure from vehicles during use, making it unsuitable for long-term use.

The object of the present invention is to eliminate such drawbacks, to provide a pedestal for a warning column for civil engineering work that can be manufactured at low cost and has excellent durability.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

The pedestal 7 of the warning pillar for civil engineering work in this embodiment is made by using the rim of a discarded light vehicle wheel. The rim 3, with only the flange 1 and the cylindrical part 2 left on one side by scraping off the part indicated by , is laid down horizontally with the flange 1 facing down, and as shown in FIG. Four reinforcing bars 4 extending from the inside toward the center are arranged at equal angular intervals and their base ends are fixed to the inner periphery of the cylindrical part 2 by welding, and a short fitting column 5 made of iron pipe is attached to each reinforcing bar. The fitting column 5 is fixed to the tip of the fitting column 5 by welding and stands vertically on the axis of the rim 3, and the concrete 6 filled inside the rim 3 is raised to the extent that the upper part of the fitting column 5 is exposed. The reinforcing bars 4 that fix the mating column 5 serve as reinforcing bars, and the hardened concrete 6 is hardened into a spherical shape on the surface of the rim 3.
is strongly connected to.

As shown in Figs. 2 and 3, the struts 8 are made of a hollow material made of a synthetic resin such as hard vinyl chloride, and are attached to the circumferential wall at two positions, upper and lower, in pairs that are elongated in the vertical direction and correspond to each other. Hole 9 is transparent,
A flashing light 12 is attached to the upper end, and the flashing light 12 is an incandescent light bulb 10 that is lit by a commercial power source or a battery and is covered with a translucent red cover 11. Fit it in place and set it upright.
By passing the cotter pin 13 through the through holes formed in the fitting column 5 and the column 8, the warning column 15 is fixed in an unmovable manner. Note that the split pin 13 is connected to an anchor 16 driven into the concrete 6 via a chain 17 to prevent it from being lost.

These warning pillars may be placed around the construction site as they are, but as shown in Fig. 3, they are made of synthetic resin and are formed at both ends of the through plate 18, which has a vertically elongated hollow rectangular cross section. The locking part 19 is attached to the support 8
A continuous protection fence in one direction may be constructed by fitting a large number of warning posts 15 into the mounting holes 9 and sequentially connecting them.

In addition, as shown in FIG.
By forming the hole 21 into which the pedestal 7 and the support column 8 can be fitted, when the pedestal 7 and the support column 8 are separated and transported, the other pedestal 7
By fitting the fitting columns 5 into the holes 21 and stacking them, it is possible to reduce the bulk.

In addition, as shown in Fig. 4, two fitting posts 5 are erected on a pedestal 7, and a large number of hard vinyl chloride pipes are connected vertically to a horizontal frame in which hard vinyl chloride pipes are connected by joints. The pillars 2 on both sides of the fence 20 have the flashing lights 12 attached to the upper part of the center.
Pedestals 7, 7 arranged with the lower ends of 1, 21 spaced apart
A protective fence may be constructed by fitting the fences 20 externally onto the fitting posts 5 and erecting them, and connecting a large number of fences 20. In addition, by making the pipe constituting the fence 20 a paper cylinder whose periphery is coated with a heat-shrinkable resin film, it is possible to improve the strength and reduce the weight.

As specifically explained in the above examples,
The base of a warning post for civil engineering works of this invention is comprised of the rim of an automobile tire wheel, with one flange removed, laid face down with the other flange facing down, and an engaging post into which the lower end of the warning post can be freely attached and detached is erected, and the rim is filled with concrete so that the upper part of the engaging post protrudes upward and is fixed.By utilizing the rim of a discarded automobile tire wheel and filling it with concrete, it is possible to reduce the amount of concrete used to manufacture a base of a certain weight and size, and since the side circumference, which is prone to breakage, is covered by a steel rim, it is highly durable, and since the underside of the base is expanded in diameter by the flange, it is also highly stable.
