Title:
ANTI-COLLAPSE SOUND BARRIER OF ROAD AND ANTI-COLLAPSE INSTALLATION METHOD OF SOUND-ABSORBING PLATE OF SOUND BARRIER THEREOF
Document Type and Number:
Japanese Patent JP2018091129
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide fall prevention of a sound-absorbing plate of a sound barrier provided in an expressway and the like.SOLUTION: A sound barrier composed of a sound-absorbing plate 10 supported by an adjacent support column 2. A wire fastener 20, a wire holder 30, and a wire connecting member 40 are fixed to the support column 2 on both the ends of a fall prevention installation section A, the support column 2 of an excess length storage section B, and each sound-absorbing plate 10 of the fall prevention installation section A, respectively. A wire 50 supported by the wire fastener 20 is stretched tightly in the longitudinal direction of the sound barrier passing in front of each sound-absorbing plate 10 provided within the fall prevention installation section A. The wire 50 passing in front of each sound-absorbing plate 10 passes through a hole of the connecting member 40 secured to each sound-absorbing plate 10 to be supported by each of the connecting member 40. The wire 50 is held at both the ends thereof by the wire holder 30, the wire holder 30 is released from holding an end metal fitting upon receiving a tensile force beyond a predetermined value, and end metal fitting abuts on the wire fastener 20 and is clamped.SELECTED DRAWING: Figure 1
