Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a raised column for a protective fence, and more particularly to a raised column for a protective fence that can be easily constructed and can be constructed at low cost.

[0002]

[Prior Art]

 Conventionally, there is one disclosed in Japanese Utility Model Laid-Open No. 64-37513 as a raised pillar for a protective fence for increasing the height of existing guard rails, guard pipes, etc. along with road surface overlays, etc. Prior art). Hereinafter, this prior art will be described with reference to the drawings. FIG. 8 is a front view showing a prior art raised rod for a protective fence, and FIG. 9 is a bottom view of the same. As shown in FIG. 8 and FIG. 9, a conventional protection fence raised column 1 has a cap 2 at the upper end, which has the same outer diameter dimension as the existing column (not shown) of the protection fence. A pipe 3, a horizontal beam mounting bracket 4 fixed to the outer surface of the upper portion of the pipe 3, and a bolt hole 5A to be inserted into the upper portion of the existing column fixed to the inner surface of the lower portion of the pipe 3 were formed. And a pair of connecting plates 5 curved in an arc shape as a connecting body.

In order to fix the raised pillar support 1 for the protective fence to the existing support pillar of the protective fence configured as described above, the cap of the existing support pillar is removed, and the connection plate 5 of the raised support pillar 1 is supported by the existing support fence. Insert in the top of the. Then, the bolt is inserted into the bolt hole formed in the existing support and the bolt hole 5A of the connecting plate 5, and the bolt is tightened. As a result, the raised pillar 1 and the existing pillar of the protective fence are connected to each other.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional raised pillar for a protective fence has the following problems. That is, it is necessary to form the bolt holes 5A in the connection plate 5, and at the time of construction, it is also necessary to form the holes for the bolts to be inserted into the bolt holes 5A of the connection plate 5 on the existing support posts of the protective fence. . Since the bolt holes to be formed on the existing columns are to be drilled on site, it takes time and labor, and it is necessary to align the bolt holes with each other, so that adjustment is troublesome. , Leads to an increase in construction costs. Therefore, an object of the present invention is to provide a raised pillar for a protective fence which can be easily constructed and is inexpensive to construct.

[0005]

[Means for Solving the Problems]

 This invention is directed to a pipe having a cap at the upper end, which has the same outer diameter as that of the existing support column of the protective fence, a bracket for mounting the horizontal beam fixed to the outer surface of the upper portion of the pipe, and the pipe of the pipe. A connection body fixed to the inner surface of the lower part and inserted into the upper part of the existing support column, and after inserting the connection body into the upper part of the existing support column, the outer peripheral surface of the upper end of the existing support column and the outer peripheral surface of the lower end of the pipe. And a band for connecting the existing support column and the pipe to each other.

Next, an embodiment of the raised pillar for protection fence of the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an embodiment of a raised fence support for a protective fence of the present invention, FIG. 2 is a bottom view of the same, and FIG. 3 is a plan view showing a band of the raised fence support for a protective fence of the present invention. FIG. 4 is a partial front view showing a state in which the raised pillar for protective fence of the present invention is connected to an existing pillar of the protective fence. As shown in FIG. 1 to FIG. 4, the protective fence raised pillar 6 of the present invention has a pipe 9 having a cap 8 at the upper end, which has the same outer diameter as the existing pillar 7 of the protective fence. And a horizontal beam mounting bracket 10 fixed to the outer surface of the upper portion of the pipe 9, and an arc shape as a connecting body fixed to the inner surface of the lower portion of the pipe 9 and inserted into the upper portion of the existing support column 7 of the protective fence. It is composed of a pair of connecting plates 11 and a band 12. After inserting the connecting plate 11 into the upper portion of the support column 7, the band 12 is fixed by the bolts 13 across the upper end outer peripheral surface of the existing support column 7 and the lower peripheral surface of the pipe 9 to fix the existing support column 7 and the pipe 9. And to connect with each other.

In order to fix the protection fence raised pillar 6 of the present invention constructed as described above to the existing pillar 7 of the protection fence, the cap of the existing pillar 7 is removed and the connection plate 11 of the raised pillar 6 is already installed. Insert it into the upper end of the column 7. Next, as shown in FIG. 4, the band 12 is fixed by bolts 13 across the upper end outer peripheral surface of the existing support column 7 and the lower end outer peripheral surface of the pipe 9. As a result, the raised pillar 6 and the existing pillar 7 are connected to each other.

As shown in FIGS. 5 and 6, the connecting body of the raised pillar 6 for the protective fence of the present invention has a pair of flat plates 15 as a connecting body, to which an anti-vibration plate 15 is fixed at the lower end, as shown in FIGS. Therefore, the pipe may be a single pipe (not shown). Incidentally, as shown in FIG. 5, if the connecting positions of the connecting plate 11 and the flat plate 15 as the connecting body in the pipe 9 are made perpendicular to the road direction, it is advantageous in terms of strength against the load W.

[0009]

[Effect of the device]

 As described above, according to the present invention, it is not necessary to form a bolt hole in the connection body, and at the time of construction, it is not necessary to form a bolt hole in the existing support post of the protective fence. Since the raised pillar 6 and the existing pillar 7 can be connected to each other only by tightening the bolts, the construction can be performed easily and the construction cost can be reduced.
