Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for installing columns such as traffic signs, guardrails, etc. installed on roads, sidewalks, factory premises, etc.

[Conventional technology]

Traditionally, when installing a traffic sign or guardrail, you first dig a hole of an appropriate size at the installation location, erect a sign post or guardrail post in the hole, and then pour concrete into the gap between the hole and the post to secure it to the ground. was.

[The problem that the idea aims to solve]

This work required that the concrete be held stationary until it hardened.

Recently, the number of damaged signs and guardrails due to traffic accidents has increased dramatically.Replacement work or repositioning requires destroying the concrete foundation of the signpost or guardrail pillar and starting the work from the beginning as described above, which is extremely wasteful. It required labor and materials, inevitably increasing costs, and was uneconomical.

[Means to solve the problem]

The installation structure of traffic sign columns and guardrail columns of the present invention solves the above-mentioned conventional drawbacks, and simply buries the blocks that serve as the foundation in the ground. It can be used immediately by simply fitting the tapered part of the base block into the taper hole formed in the center of the base block.

[Effect]

Therefore, for installation and removal, the column can be easily fitted or pulled out from the foundation using the flange provided on the column, and once the taper of the column is fitted, the foundation will be firmly established without any loosening. The present invention provides a streamlined installation structure for road structure columns such as traffic sign columns and guardrail columns that is extremely easy to handle and labor-saving because the body block and column are fixed together.

〔Example〕

To explain the present invention with reference to the attached drawings, 1 is a foundation block buried underground into which columns of traffic signs and guardrails are fitted and fixed, and is a block molded from a molding material such as concrete or asphalt resin. The bottom part 9 is formed in a funnel shape,
On the circumferential side, several bulges of arbitrarily shaped root nodules 2 are provided in a radial manner to prevent movement after being buried in the ground and to improve stability, and the exposed above ground portion 10 on the upper surface has a mountain-shaped sloping shape. This is a foundation block to be buried in the ground for planting a sign column or a guardrail column, which has a tapered hole 3 formed in the center and which decreases from the upper surface to the lower surface.

The upper surface 10 of the base block 1 exposed above the ground is formed into a mountain-shaped inclined shape to allow rainwater to drain well into the fitting portion of the taper hole 3, thereby preventing water seepage and corrosion of the column. .

Reference numerals 4 and 4' designate a traffic sign column and a guardrail column, and as shown in the figure, the only difference in height is that their bases have the same structure.

5 is a column formed into a tapered shape so as to match the taper hole 3 penetrating the center of the base block 1, which has the lower part of the traffic sign column 4 and the guardrail column 4' buried underground. It is at the bottom.

Reference numeral 6 denotes a collar provided on the upper part of the tapered part 5 at the bottom of the columns 4, 4', which serves as a support for fitting, driving or pulling out the column into the taper hole 3 of the base block 1, and also serves as a tapered fitting part. The tsuba has three functions: preventing rainwater from entering the tsuba.

7 shows an example of a traffic sign installation display.

8 shows an example of installing a guardrail. Also, G indicates underground.

In this way, the foundation block 1 is stable when buried in the ground G due to the radially protruding root nodule 2 and the funnel-shaped molded part 9 on the lower surface, and even if the longitudinal pillars 4 and 4' are planted. It is stable and can withstand long-term use without any slight movement. In the illustration, the basic block body is shown in a rectangular shape.
It may be cylindrical if necessary, and if it is to be formed into a large size, reinforcing bars may be placed.

Therefore, this structure can be applied not only to traffic sign columns and guardrail columns, but also to the bases of street lights.

[Effect]

The integrated structure of the traffic sign or guardrail column of the present invention constructed in this way and the foundation block buried underground is different from the conventional method of digging a hole in the ground and erecting the sign column or guardrail column. Unlike the construction methods that involve pouring concrete and waiting for it to harden, which is expensive, it can be used immediately by burying the foundation block underground and fitting the column taper, and the buried block can be used underground. It is revolutionary in that it has great stability and prevents corrosion of the fitting contact area between the column and the foundation, increasing durability, and can be firmly fixed, making installation extremely easy and reliable. This is a column-planted structure for road structures such as traffic signs and guardrails, which has the effect of saving labor.
