SAFETY NET CLAMP AND SAFETY NET SPREADING METHOD USING THE CLAMP

PROBLEM TO BE SOLVED: To perform safety net spreading work at a high place through a remote control operation by a worker from lower a low place, while dispensing with setting a high working scaffolding. SOLUTION: A clamp operation bar 60 joined to a connection bar 37 of the clamp 11 is used to raise the clamp up to the height of the beam 9, to set the clamp while the beam is accommodated between horizontal parts 51a, 52 and an opened cam 23, and a cam switching operation bar 70, in this state, is abutted on a horizontal bar 31 and raised, to push up an operation lever 30, causing the cam to be switched from an opening state to a holding state. Thereby the clamp is fixed to a structure, after removing the clamp operation bar and cam switching operation bar, the end rope 13 of the safety net 12 is locked with a hook 53 for locking a safety net end rope provided on the shoulder surface side of a clamp vertical part 51b to spread the safety net. A series of operation can be carried out by a worker through remote control from a low place such as a platform. COPYRIGHT: (C)2011,JPO&INPIT
