  However, in the case of the guard fence post disclosed in paragraph No. 0002 of Patent Document 1, when the anchor plate of the pillar is installed on the anchor bolt embedded in the inclined ground cover, the anchor plate of the pillar is previously set. It is necessary to incline it, and it is necessary to measure the gradient carefully about the support fence post used for the slope part, and it is necessary to manufacture each support column that matches the slope. In the case of a guard fence installed in a pair of left and right, it was necessary to make the right and left pillars corresponding to the left and right slopes separately, so even if the pillars were made in advance and stocked, there are many types It was something that would reach.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a protective fence post having a structure capable of reducing the type of stock of the protective fence support.

  In order to achieve the above object, the present invention is configured as follows. That is, the protective fence support according to the present invention is characterized in that the mounting holes for attaching the cross rails are formed symmetrically on the opposite side wall and the other side wall.

  According to the protective fence support according to the present invention, the mounting holes for attaching the cross rails are formed symmetrically on the opposite side wall and the other side wall, so that they are installed in a pair on the left and right with respect to the road and the bridge. If a guard fence post corresponding to one side edge, for example, the left side is manufactured and stocked, the guard fence post can be inverted 180 ° with respect to the other side edge and the right side. Can be installed, so the number of guard fence posts to be stocked can be halved.

  In the present invention, the mounting bracket for supporting the cross rail is attached to the support through the mounting hole, and the side wall of the support is provided with a stop hole for temporarily fixing the mounting bracket in addition to the mounting hole. It may be. In this way, the mounting bracket is temporarily fixed to the side wall of the support column, the heavy horizontal rail is temporarily placed on the mounting bracket, and the support column, the mounting bracket, and the horizontal beam are fastened using the mounting bolts. Since it can be performed, the workability at the time of construction can be improved.

BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.
FIG. 1 shows an embodiment of a guard post according to the present invention. (A) is a front view, (B) is a plan view, (C) is a right side view, and (D) is a left side view. , (E) is a rear view, FIG. 2 shows one embodiment of the protective fence using the protective fence support according to the present invention, and (I) is installed on the ground surface inclined upward. FIG. 3 is a front view of the state, FIG. 3 is an exploded perspective view showing a part of FIG. 2A, and FIG. (B) is a plan view, (c) is a right side view, (d) is a left side view, (e) FIG.

  Reference numeral 1 denotes a rectangular flat base, and a support column 2 having an H-shaped cross section is erected on the upper surface of the base 1 to form a protective fence support column. When installed in an inclined place, a column 2 is erected in the vertical direction with respect to the base 1 that is inclined upward at an inclination angle θ. In addition, a pair of mounting holes 22 for mounting the cross rail 4 via the mounting bracket 3 are symmetrically provided on the side wall formed by the one flange 21a and the side wall formed by the other flange 21b of the supporting column 2 having an H-shaped cross section. It is drilled in three steps up and down. In this way, the bolts 5 can be tightened from the back side of the flanges 21a and 21b when the horizontal rail 4 is attached.

  Further, a stop hole 23 having a smaller diameter than the attachment hole 22 is formed between the attachment holes 22 and 22 formed in the left and right pairs of the flanges 21a and 21b. In order to make this stop hole 23, the web 24 provided between the flanges 21 a and 21 b of the support column 2 having an H-shaped cross section has a pair of notches 25 corresponding to the position where the stop hole 23 is made. There are three stages.

  Further, four anchor bolt holes 11 penetrating in the vertical direction for inserting anchor bolts for fixing to the ground surface are provided at four corners of the base 1 in point symmetry with respect to the center of the base 1. Yes.

  Since the base 1 is used for a support fence post, it is preferably made of a metal having high strength, and is preferably formed using a metal material such as steel, stainless steel or aluminum. About the support | pillar 2, what integrated the flange 21a, 21b and the web 24 which were formed with general purpose H-shaped steel or a flat plate by welding etc. can be used suitably. Further, like the base 1, the support column 2 is preferably formed using a metal material such as steel, stainless steel, and aluminum that can obtain high strength, and more preferably steel. And the base 1 and the support | pillar 2 are integrated by welding etc., and the support | pillar for protection fences is produced. Further, when steel is used for the base 1 and the support 2, it is preferable to prevent corrosion by performing surface treatment such as plating with zinc or painting.

  In FIG. 2, the guard fence post shown in FIG. 1 is used. First, (a) is installed on the ground surface inclined upward to the right, but is attached to the flange 21 a of the post 2. The horizontal beam 4 is attached to the mounting bracket 3 and the horizontal beam 4 is mounted in three upper and lower stages. Next, (b) is a state where it is installed on the ground surface inclined downward to the right at an angle opposite to (b), but the same guard fence post as used in (b) is inverted 180 °, The cross rail 4 can be attached to the flange 21 b of the support column 2 via the mounting bracket 3. Therefore, since it is possible to cope with an upward slope and a downward slope using the same protective fence post, when the protective fence post is stocked, the type can be halved. Even when installing on a flat ground surface with no slope, as with the sloped ground surface, the guard fence support placed on one side edge of the road or bridge is inverted 180 ° to the other side edge. Since it can be installed, its inventory can be halved.

  Here, although the crosspiece 4 may be directly attached to the attachment hole 22 formed in the flange 21a of the support column 2, it may be attached via the attachment fitting 3 as shown in FIG. In this case, in order to facilitate the construction, in addition to the mounting hole 22 in the flange 21a of the support column 2, a stop hole 23 having a smaller diameter than the mounting hole is drilled, and a similar small hole 31 is drilled in the mounting bracket 3. It is preferable that the mounting bracket 3 can be temporarily fixed to the support column 2 by inserting and fastening the rivet 6 or the like into the stop hole 23 and the small hole 31. Further, instead of the small hole 31 formed in the mounting bracket 3, a pin-like protrusion may be inserted into the stop hole 23 and temporarily fixed.

  FIG. 4 shows another embodiment of the protective fence post according to the present invention. (A) is a front view, (B) is a plan view, (C) is a right side view, and (D) is a left side. The figure (e) is a rear view. The difference from the protective fence support shown in FIG. 1 is that the lower part of the web 22 of the support 2 is made wider as it goes downward. By adopting such a shape, the strength of the guard fence post can be improved, which can be effective when an external force such as a vehicle collision is applied to the guard fence pillar.

  In this embodiment, four anchor bolt holes 11 and three mounting holes 23, mounting brackets 3 and cross rails 4 are provided. However, the present invention is not limited to this. Depending on the required strength, a suitable quantity may be provided.

  The protective fence support according to the present invention is provided with a pair of left and right protections for roads and bridges because the mounting holes for attaching the cross rails are symmetrically drilled on one side wall and the other side wall. In the fence, if a guard post for one side edge, for example, the left side is manufactured and stocked, the guard post for the other side edge and the right side is inverted by 180 ° and installed. The number of types of supporting fence posts to be stocked can be halved, and by forming a protective fence using the stocked supporting fence posts, the period until the completion of the protective fence can be shortened. Therefore, it can be suitably used as a support fence post with great advantages in terms of delivery and cost.
