<P>PROBLEM TO BE SOLVED: To facilitate transportation and installation at a construction site and to surely prevent scattering of crushed pieces generated during chipping work of pavement materials and concrete materials in a simple construction such as road repair. <P>SOLUTION: In a scattering prevention fence which comprises four rectangular frame bodies 1A-1D in the same shape, the two rectangular frame bodies 1B and 1C adjacently positioned inside are hinge-connected to each other at the inner side edge, respective outer side edges of the two rectangular frame bodies 1B and 1C and respective inner side edges of the two rectangular frame bodies 1A and 1D positioned outside are hinge-connected to each other, and they can be deformed into a spread state that the rectangular frame bodies 1A-1D are connected adjacently to each other and a stored state that the rectangular frame bodies 1A-1D are folded on top of each other while being bent roughly into an M shape in the plan view. Also, a sheet body 2 is mounted so as to cover a frame space of the rectangular frame bodies 1A-1D, an opening 25 is formed at the sheet body 2 in a range of a fixed height or higher from the lower side, and a net body 26 is put on the opening 25. <P>COPYRIGHT: (C)2012,JPO&INPIT |
