DEVICE FOR TESTING A PULL-OUT OF A PROTECTIVE NET, CAPABLE OF TESTING A PULL-OUT OF A PROTECTIVE NET ACCORDING TO ROCK FALL LOADS

摘要

PURPOSE: A device for testing a pull-out of a protective net is provided to test the pull-out performance of a protective net under a condition similar to an actual condition in a site and to obtain the excellent reliability.;CONSTITUTION: A device for testing a pull-out of a protective net(100) comprises a protective net frame(110), pull-out force generators(120,130), and a measurement unit(150). The protective net frame supports a protective net so that the protective net is horizontally installed. The pull-out generators add a pull-out force on the protective net from downward to upward by corresponding to loads added on the protective net. The measurement unit measures the state of the protective net when the protective net is pulled-out by the drawing force generators. A size of the protective net frame is adjustable by corresponding to a size of the protective net. At least a part of the pull-out force generator comprises a plurality of frame members(112) having wheels(112a), thereby becoming movable.;COPYRIGHT KIPO 2012
