SOUND INSULATING BOARD IMMOBILIZATION STRUCTURE SUCH AS ROAD SOUND INSULATION WALL, SOUND INSULATING BOARD FASTENER AND SOUND INSULATING BOARD
Document Type and Number:
Japanese Patent JP2016118064
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sound insulating board immobilization structure that is implemented in a sound insulation wall constructed along an automotive road and a railroad, and a sound insulating board fastener for use in the sound insulating board immobilization structure.SOLUTION: A first vertical side 12 for forming a V-shape of a sound insulating board fastener 1 curves from an upper end toward a second vertical side 13 of the other side, and is made to curve from the vicinity position to the second vertical side 13 toward the lower part of first vertical side 12 to form an inside support side part 14. The second vertical side 13 of the other side is formed in a coming-out prevention side 15 obtained by bending an upper end in the outward direction and inserting it to a stack gap of the mutual sound insulating boards. An immobilization protrusion 10 sticking out outwardly is formed in a lower part more than the coming-out prevention side 15 of the second vertical side 13. The sound insulating board fastener 1 is fitted into the gap between a sound insulating board 2 and a groove wall 31. An immobilization hole 23 where the immobilization protrusion 10 of the sound insulating board fastener 1 is fitted is provided in the sound insulating board 2. A wire 4 is made to pass through a wire insertion hole 16 of the sound insulating board fastener 1, and the immobilization protrusion 10 of second vertical side 13 is fitted into the immobilization hole 23 of the sound insulating board 2.SELECTED DRAWING: Figure 1
