{Columns for reinforced stiffening streetlights}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a strut of a streetlight installed on a road or a park, and more particularly, to a strut for a streetlight of a straight or tapered shape, a plurality of reinforcing plates, and a reinforcing rod for connecting the reinforcing plates The present invention relates to a seismic design for earthquake resistance and an earthquake-resistant design for earthquake-resistant design capable of preventing strong breaks and preventing breakage or breakage of the column due to reinforcement of the lower stiffness of the streetlight support.

Generally, roads are equipped with streetlights that allow people to perceive the situation around the roads or to make it easy for the automobile or pedestrians to move at night. In addition to roads, alleys, parks and gardens have parks And the exterior installation such as the street lamp and the park in the present invention will be referred to as a street lamp.

In general, a streetlight with various purposes and purposes has a column fixed to the ground and a cross bar projecting from the upper end of the column to one side or both sides of the column, .

Here, in the case of the above-mentioned cross bar, various shapes, shapes and shapes will be produced depending on the purpose of installation of the street lamp or other landscape and interior needs.

In such a streetlight, the above-mentioned strut must have a predetermined physical strength and a sufficient supporting force. In order to satisfy such a condition, it is general to use a steel pipe made of a metal material. That is, the support made of the metal steel pipe has excellent durability against external impact, and can maintain excellent supporting force even in bad weather accompanied by strong wind.

In addition, an inspecting port for connecting the grounded power cable and the lamp is formed on the lower side of the strut, and the lamp is illuminated by electrically connecting the underground cable and the lamp from the inspecting port will be. In particular, in the case of a streetlight having an LED light source, a converter is mounted inside the inspection hole, and in the case of a streetlight by a general plasma light source, a ballast or a transformer is mounted.

Since such an inspection port is formed by cutting and opening the lower part of the pillar of the streetlight, it is provided with a separate cover body so that the inspection port is sealed by connecting the cover body to the inspection port.

Even if the above-mentioned street lamp support is manufactured using a metal steel pipe, if an earthquake occurs more than the physical rigidity of the support, or when strong winds are applied, the support member breaks or breaks due to fatigue failure at the lower end of the support In the case of breakage or breakage of such street lamps, it is true that the street lamp itself is damaged and the risk of secondary accident is very high.

Accordingly, various types of reinforcement structures for the strut of the streetlight as described above are applied, and the tendency is being improved so that a stable and stable supporting force can be continuously maintained from earthquakes or strong winds.

That is, as shown in Japanese Patent No. 10-1414783, there are provided a streetlight supporting column, a support angle fixedly installed at the lower end of the streetlight supporting bar, and a supporting angle fixedly installed on a bottom face on which the streetlight supporting bar is installed, And an earthquake-resistant means installed between the supporting angle and the floor angle to protect the streetlight supporting platform from damage by absorbing vibration due to an external force.

Further, a flange having a fastening hole as shown in Japanese Patent No. 10-1589159 and installed on the ground; A ridge installed perpendicularly to the flange; A lamp mounted on one side of the lamp; And a supporter for reinforcing the rigidity of the ridge so as to suppress the bending deformation of the ridge, so that the bending deformation due to the external force or the stress generated in the street lamp can be suppressed, A rigid reinforced streetlight has been enacted and registered to extend the life of the streetlight itself.

In addition, a supporter preparation step of preparing a supporter to reinforce the rigidity of a spiral groove to which the luminaire is installed, as in the case of the Japanese Patent No. 10-1589162, and to suppress the flexural deformation of the spiral groove; A flange installing step of installing a flange at a lower end of the spiral groove; And a supporter installing step of installing the supporter on the ridge, and a rigid reinforced street lamp manufactured by the manufacturing method, wherein a bending due to an external force or a stress generated in the street lamp A manufacturing method of a rigid reinforced street lamp capable of effectively preventing a street lamp from being damaged because it can suppress deformation and prolonging the life of the street lamp itself has been enacted and registered.

Further, a flange having a fastening hole as shown in Japanese Patent No. 10-1615202 and installed on the ground; A ridge installed perpendicularly to the flange; A lamp mounted on one side of the lamp; And a supporter for reinforcing the rigidity of the ridge so as to suppress the bending deformation of the ridge, so that the bending deformation due to the external force or the stress generated in the street lamp can be suppressed, Strengthened reinforced street light that can extend the life of the street light itself has been enacted and registered.

As described above, in the past, various reinforcement structures for the lower fixing flange of the streetlight support have been applied, thereby suppressing the collapse of the support pillars or the bending at the lower end portion. If necessary, the tensile steel wire is fixed So that reinforcement of the lower end of the strut can be performed.

However, the existing stiffness reinforcement structure and shape are limited to the flange portion or the fixed installation portion with the ground as described above. When strong wind or earthquake occurs due to the reinforcing structure with respect to the fixed flange portion, But rather breakage or breakage occurs at the lower end of the support, and breakage due to such breakage or breakage can not be overcome by reinforcement of the flange portion.

Further, in the case of a structure in which a tensile steel wire is fixed to the inside of the lower end of the strut, the above tensile steel wire is fixed in three directions or four directions. In this case, rigidity reinforcement is performed in the direction in which the tensile steel wire is located, , There is still a tendency to bend or break in a direction in which the tensile steel wire is not located in the case of an earthquake or a strong wind having an unpredictable direction.

FIG. 1 is an overall view of a streetlight having a strut to which a reinforcing structure according to the present invention is applied, FIG. 2 is an overall perspective view of a stiffener according to the present invention, and FIG. FIG. 4 is an exploded perspective view of a stiffener according to the present invention, and FIG. 5 is an overall sectional view of a stiffener according to the present invention.

As shown in the drawing, the stiffening structure according to the present invention is applicable to both a flat-type strut having the same thickness at the upper and lower ends, or a tapered strut having a gradually decreasing thickness toward the upper end. So that the seismic design and the stiffness reinforcement can be carried out with respect to the lower portion of the column where bending or breakage frequently occurs as the column 100 is installed inside the lower end portion of the column 100.

The upper fixing plate 10, the intermediate fixing plate 20 and the lower fixing plate 30 are sequentially and downwardly fixed from the upper side to the lower side of the support pillars 100, And the lower fixing plate 30 may be close to the lower end of the support 100. The intermediate fixing plate 20 may be fixed to the upper fixing plate 10 and the lower fixing plate 30, It would be most ideal to be located in the middle between the fixing plates 30. [

The upper fixing plate 10 and the intermediate fixing plate 20 are fixed in mutually tensioned state by a plurality of upper reinforcing rods 40 and 40. The intermediate fixing plate 20 and the lower fixing plate 30 The upper fixing plate 10, the intermediate fixing plate 20 and the lower fixing plate 30 (hereinafter, referred to as " upper fixing plate 30 ") are fixed to each other by a plurality of lower reinforcing rods 50 ) May be formed with through holes for installing electric wiring and built-in water as necessary.

The upper fixing plate 10 has an outer diameter corresponding to the inner diameter of the strut 100 and is firmly fixed to the inner surface of the strut 100 through welding or the like. The central fixing hole 10 has a central fitting hole 11 And the upper split holes 12 and 12 'in three directions or in four or more directions from the central fitting hole 11 are vertically penetratingly formed at regular intervals.

The lower fixing plate 30 is also formed with a central fitting hole 31 and vertically penetrates the lower fixing holes 32 and 32 'radially from the central fitting hole 31. The intermediate fixing plate 20 The number of upper division holes 12 and 12 'formed in the upper fixing plate 10 and the number of upper division holes 12' formed in the upper division plate 10 in the case of the composite division holes 22 and 22 ' Are formed opposite to each other with the number of the lower division holes 32 and 32 'formed in the fixing plate 30 and the number corresponding to all of the lower division holes 32 and 32'.
