To provide a scattering prevention system capable of easily preventing the scattering of crushed material in demolition of an existing building and capable of being lifted according to the progress of a demolition work.SOLUTION: A scattering prevention system 1 prevents scattering of crushed material in demolition of an existing building 2. An open hole 4 is formed at a floor slab 3 of the n-th floor to be demolished of the existing building 2. Open holes 4A, 4B are formed at floor slabs 3A, 3B of the (n-1)th floor and (n-2)th floor situated below the floors to be demolished. The scattering prevention system 1 comprises a plurality of support poles 20 inserted into the open holes 4, 4A, 4B and with a top projecting above the floors to be demolished, a cure sheet 30 stretched between the tops of the plurality of support poles 20 and an electric chain block 40 for lifting the support pole 20 while suspending and supporting the same.SELECTED DRAWING: Figure 1
【課題】既存建物の解体時に破砕物の飛散を容易に防止でき、かつ、解体工事の進捗に伴って適宜昇降可能な、飛散防止システムを提供すること。【解決手段】飛散防止システム１は、既存建物２の解体時の破砕物の飛散を防止する。既存建物２の解体対象階であるｎ階の床スラブ３には、貫通孔４が形成されている。解体対象階の下階である（ｎ－１）階および（ｎ－２）階）の床スラブ３Ａ、３Ｂには、貫通孔４Ａ、４Ｂが形成されている。飛散防止システム１は、貫通孔４、４Ａ、４Ｂに挿通されて頂部が解体対象階の上方に突出する複数の支柱２０と、複数の支柱２０の頂部同士の間に展張された養生シート３０と、支柱２０を吊り下げ支持しつつ昇降させる電動チェーンブロック４０と、を備える。【選択図】図１
