It comprises fastening means of an operator to a fixed part of the construction, which include a harness or safety belt and a snap link; an anchorage element (2), adapted for being inserted into a mass of concrete (3) and remaining solidified to the same after setting, which links the device to said fixed part of the construction; and a stanchion (4) movably coupled at its lower part to said anchorage element and joined at its upper part to a rope (5) which, at its lower end (7) is linked to the said fastening means, and which can turn with respect to the vertical axis (8) of the stanchion. Once the concrete has set, the operator remains firmly fastened with the possibility of moving freely within an essentially circular field of action (24), around said vertical axis. <??>Particularly applicable to safety for work on horizontal formworks. <IMAGE> |
