CONNECTING HIGHSTRENGTH STEELS WITH HIGHSTRENGTH SCREWS

VERBINDUNG HOCHFESTER STAEHLE MIT HOCHFESTEN SCHRAUBEN

FOR CONNECTING THESE STEELS IT IS SENSIBLE TO USE HIGH-STRENGTH SCREWS AS WELL AS WELDS, BECAUSE GOOD UTILIZATION IS POSSIBLE BOTH FOR THE BASIC MATERIAL AND FOR THE BOLTS BECAUSE OF THE MUTUAL AGREEMENT OF THE HIGH STRENGTHS. BEHAVIOUR IS NOT YET CLEAR, PARTICULARLY IN THE CASE OF CONNECTIONS WITH A SHEAR REVEAL ACTION, BUT ALSO IN THE CASE OF HV CONNECTIONS. WITH THE FIRST-NAMED CONNECTIONS DIFFICULTIES EXIST WITH RESPECT TO THE PLASTIC BALANCE UNDER REVEAL STRESS, PARTICULARLY WHEN AS A RESULT OF INACCURATE ALIGNMENT OF THE BOREHOLES AND A REVEAL OF D = 1MM AND MORE, SOME SCREWS, THROUGH BEING USED TOO EARLY, QUICKLY UTILIZE THEIR FULL BEARING CAPACITY AND ARE OVERSTRESSED. THE SAME GOES FOR HVP CONNECTIONS.
