PURPOSE:To provide braille point blocks for a magnetic induction system with high detection performance by applying paint including soft magnetic powder onto the surfaces of basic blocks. CONSTITUTION:The surface of a concrete block is applied with paint formed by fixing soft magnetic powder with polylethane resin, and is further applied with acryl resin as an upper coat thereon. It is thus possible to provide braille point blocks for a magnetic induction system with high detection property, whereby signs at a station or public road can be reformed to help the blind or weak-sighted persons with a simple construction. |
