PURPOSE:To reduce a load on the bottom of a base to prevent it from being deformed by providing a projected body at a position below a boundary between an anchor concrete layer, on which a beacon light mounting table is fixed, and its upper paved layer. CONSTITUTION:A projected ring body 8 is closely fitted and fixed on the outer periphery of the cylindrical body 2 of a base 1. In addition, multiple supports 9 as reinforcement member and rotation stopper are fixed on the upper surface of the projected body 8 and the outer periphery of the cylindrical body 2 in circumferential direction at a specified interval. Next, the projected body 8 is fixed on the outer periphery of the cylindrical body 2 so that it may be positioned at a boundary between the anchor concrete layer 11 and its upper paved layer 12 of the ground 10. Thus, when a load such as aircraft, etc., is applied on a light exposed on the ground, it is distributed by the projected body 8 fixed by the strong anchor concrete layer, to reduce the load on the base 1. |
