[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting column which is provided with a lighting device on a column and which is erected by burying a base of the column in the ground.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional example. A lighting column 7 having a lighting device 6 at the head of the column 2 is erected with the base of the column 2 buried in the ground. By the way, as shown in FIGS. 4A and 4B, in order to prevent the column 2 from tilting and sinking,
A cylindrical root machine 5 having a substantially circular cross-section is attached to the base of the column 2 buried underground so as to penetrate in a cross shape.

[0003]

However, in the above-described conventional cylindrical rooting machine 5 having a substantially circular cross-sectional shape, when an external pressure load such as a wind pressure load or an artificial load is applied to the lighting column 7, There is a problem that the lighting column 7 tilts or sinks due to insufficient strength. In addition, since the root machine 5 penetrating through the column 2 moves relatively easily in the longitudinal direction, the root machine 5 is displaced from its original position when the lighting column 7 is buried in the ground, and it is difficult to construct. There are also problems.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a lighting column which can be easily buried underground and prevents tilting and sinking.

[0005]

According to a first aspect of the present invention, there is provided a lighting column in which the base of a column having a lighting fixture is buried in the ground and is erected, the two roots having a substantially rectangular cross section. the annexed by intersecting the and cross to penetrate the base of the pillar OMRON will provided with the cut and raised shaped projection on top of the intersection with the other Ne械 of one Ne械, the protrusion and the fitting That is , a fitting recess is provided in the other machine .

[0006]

[Action] devised according to claim 1, the base of the lighting column erected the base of the columnar body provided with the luminaire and buried in the ground, two Ne械 the pillar cross-sectional shape is substantially L-shaped The root of one of the roots intersecting the other root is provided with a cut-and-raised protruding part, and the fitting recess fitted to this protruding part is inserted into the other root. since there is provided the in Ne械, strength is increased with respect to external pressure load applied to light poles,
It is possible to prevent tilting and subsidence of the pillars, and because the two machines do not move easily in the longitudinal direction, and when the lighting pillar is buried in the ground, the machines do not deviate from their original positions. In addition, the fitting structure of the two root machines is simple, easy to form, and can be securely fitted.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 (a) and 1 (b), a root machine 1 according to the present embodiment is, for example, formed by bending a plate material in a longitudinal direction at a bending angle of approximately 90 degrees and bending the plate material in two at the center. It is formed. In addition, the manufacturing method of the root machine 1, a bending angle, etc. are not the meanings limited to this. Winding load or artificial load is applied to the lighting column 7, which is buried under the ground attached to the column 2 by penetrating the column 2 and crossing the column 2 so as to cross the column 2. When an external pressure load is applied, the underground machine 1 also receives pressure. When the area where the root machine 1 receives pressure, that is, the pressure receiving area, is compared with the case of the cylindrical root machine 5 as shown in FIG. 4B, the cylindrical root machine 5 is formed of the same material as the above-mentioned plate material. Assuming that the wall thickness and the cross-sectional area are substantially equal to the root machine 1 of the present embodiment, the pressure receiving area of the root machine 1 of the present embodiment is about 2.2 times the pressure receiving area of the cylindrical root machine 5. Become. In other words, by making the cross-sectional shape of the root machine substantially rectangular, the strength of the root machine against an external pressure load increases. As a result, the lighting column 7 can be prevented from tilting or sinking under an external pressure load.

As shown in FIG. 2, two root machines 1a
And 1b, two cuts 3 are provided in the longitudinal direction at the top of the lower root machine 1a at the crossing point of the cross,
The root machine 1 on the upper side so as to fit each
The fitting recess 4 made of a square hole is provided at two places in b. Therefore, since the two root machines 1a and 1b penetrate through the pillar body 2 and are fitted and fixed at the two cut-and-raised portions 3 and the fitting concave portion 4 formed of a square hole, they may be displaced in the longitudinal direction. There is no. That is, since the root machine 1 does not deviate from the original position when the lighting column 7 is buried in the ground, the construction is easy. In addition, the fitting structure between the cut and raised 3 and the fitting recess 4 is
Simple, easy to form and can be securely fitted
It is.

[0009]

According to a first aspect of the present invention, there is provided a lighting column having a base having a lighting fixture and erected by burying the base of the column in the ground.
Two roots with a substantially U- shaped cross section penetrate the base of the column and are attached so as to cross each other, and the other root of one root
A cut-and-raised protrusion is provided at the top of the part that intersects with the root, and a fitting recess that fits with the protrusion is provided on the other root. When an external pressure load such as a mechanical load is applied, the pressure receiving area on which the machine receives pressure can be made larger than before, increasing the strength against the external pressure load applied to the lighting column, and preventing the column from tilting and sinking Because the two root machines do not move easily in the longitudinal direction due to the fitting of the protrusions and the fitting recesses, the root machine does not shift from its original position when the lighting pillar is buried in the ground, so construction is possible. In addition, there is an effect that the fitting structure of the two root machines is simple, easy to form, and can be securely fitted.
