In the fence for roads described in Japanese Utility Model Laid-Open No. 6-10565,
Since the bracket has an arcuate surface, the bracket can be rotated along the arcuate surface, so that the direction of the bracket attached to the protective fence post can be changed vertically and horizontally. Therefore, even if the road is bent, climbed, or descended, and the beam pipe is in a direction different from the right angle to the guard fence post, the bracket is rotated in the direction of this beam pipe and the beam pipe is bracketed. Although it is convenient because it can be attached to a computer, there is a problem that the number of parts increases due to the use of the auxiliary member, the cost becomes high, and it is difficult to perform the installation.

此のボルトに螺入されたナットは隠れて見えなくなる。Further, since the beam pipe mounting portion has a shape covering the half circumferential surface of the beam pipe, that is, a shape in which the remaining half circumferential surface is chipped, a hand is inserted from the chipped portion and the bolt is inserted into the column mounting portion. Can be inserted into the through-hole of the guard fence post through the through hole, and a nut can be screwed into this bolt to easily attach the bracket mounting portion to the guard fence post. In addition, since the through hole of the support column mounting portion is provided at a position that is hidden when the beam cover is mounted on the beam pipe mounting portion, when the beam cover is mounted on the beam pipe mounting portion later, the through hole is inserted into the through hole. Bolts,
The nut screwed into this bolt is hidden and invisible.

外周面から突出することがない。Thereafter, the end of the beam pipe is inserted into the beam pipe attachment portion, and a beam cover is attached to the chipped portion of the beam pipe attachment portion, and the beam cover is attached to one of the beam pipe attachment portion and the beam cover. The beam pipe is attached by penetrating the hole of the beam pipe from the provided through hole and screwing a bolt into the screw hole provided on the other side. Then, on the outer peripheral surface where the through hole is provided, there is provided a recess in which the head of the bolt enters at the periphery of the through hole, and the screw hole on the opposite side does not penetrate, so the bolt is removed from the outer peripheral surface of the beam pipe. Does not protrude.

プをブラケットに取り付けることができる。Further, the mounting surface of the beam pipe mounting portion and the mounting surface of the beam cover provided with the through holes and the screw holes are as follows.
When the end of the beam pipe is inserted into the beam pipe attachment part and the beam cover is attached, the central part is surrounded by the outer peripheral surface of the beam pipe, and it gradually expands as it goes to both ends. You can change the direction of the beam pipe up, down, left and right as much as you can. Therefore, even if the road is bent, climbed or descended, and the beam pipe is in a direction different from the right angle direction, attach the bracket to the protection fence post at a right angle and change only the direction of the beam pipe. The beam pipe can be attached to the bracket.
