| 摘要 |
The present invention concerns a device for anchoring in rigid terrains such as boards, or floors of concrete, asphalt, rock,... support posts for security barriers and parapets, by means of bolts partly embedded in the ground and fixed therein by chemical or mechanical means, where the emergent part traverses in succession the anchoring plate of the barrier post, one or more washers and closing nuts which are those that fasten the bolt to the anchoring plate. The washers have the capacity to behave as fusible elements which, when subjected to a vertical traction load greater than a predetermined value, are deformed and traversed by the closing nut, which, once released from the washer, traverses the corresponding aperture of the anchoring plate, which is larger than the closing nut, thereby unbolting the connection between the plate and bolt. |
