SCATTERING PREVENTION DEVICE AND SCATTERING PREVENTION METHOD

HIRANO YUJI / MUTO TEPPEI

To provide a scattering prevention device and a scattering prevention method which can efficiently prevent scattering of an object to the outside at the time of demolition of a building of a plurality of stories.SOLUTION: A scattering prevention device for preventing scattering of an object to the outside from a building includes a plurality of struts 10, 20, 30 and 40 erected in the periphery of the building, first wires W1u and W1d, protective nets N1 and N2, second wires W2u and W2d and a tension adjustment device. The first wires W1u and W1d are erected between the upper parts of the facing struts 10, 20, 30 and 40 among the plurality of struts 10, 20. 30 and 40. The protective nets N1 and N2 are developed while being supported by the first wires W1u and W1d. The second wires W2u and W2d are brought into contact with the lower surfaces of the protective nets N1 and N2 between the upper parts of the adjacent struts 10, 20. 30 and 40 so as to face the protective nets N1 and N2. The tension adjustment device adjusts tension forces of the first wires W1u and W1d and the second wires W2u and W2d.SELECTED DRAWING: Figure 2
