PROBLEM TO BE SOLVED: To make installation reliable and maintenance easy by composing a pole of a resin pole section, a resin base section to which the pole section is fixed in a detachable manner, and an anchor section that tightens the base section with bolts. SOLUTION: A road sign pole is made up of a pole section 101, a base section 102, a tightening bolt 103 and an embedded anchor 104. To install it on a road, the anchor 104 is embedded and fixed in a prescribed position, the base section 102 is placed and fixed reliably with the tightening bolt 103. And then the pole section 101 is fitted into a circular groove 109 in the base section. If the pole section 101 breaks, only the pole section is replaced. It can be removed easily from the base section 102 by blowing compressed air from a pore on the top of the pole section. Therefore, since the tightening bolt are used for fixing the anchor section and the base section, they can be fixed securely and can be maintained easily. |
