(57) Abstract This invention has very high mechanical strength in manner and the device which it is attenuated or absorbs the suitably it joins to structure such as portion of the civil engineering works facility great sudden load, or, at least 1 it is locked junction to structure (1) possesses 1st plate and very high mechanical strength and the load must be transmitted, the structure (2) the base material or 1 it is locked junction to another element it can provide with the 2nd plate at least, the load where the 1st plate and it slides the 2nd plate and accompanies friction and this is to touch mutually, absorb or be attenuated shouldWhen happening, it can provide the pyro technique feature (10) which is activated, that pyro technique feature the 1st plate and pressure welding does the 2nd plate mutually under pressurizing, the plate regards manner and the device which feature that operation as an attenuation device or a blocking device with that.
