Rögzítőelemek kúpos kiszakadása tűzkárosodott betonban

Kulcsszavak: tűzkárosodott beton, rögzítéstechnika, ragasztott kötőelem, alámetsző rögzítőelem szakadókúpos tönkremenetel

Absztrakt

Kutatásunk során tűzkárosodott betonba elhelyezett rögzítőelemek teherbírását elemeztük. A vizsgálatainkkal célunk volt a tűzesetekben károsodott vasbeton szerkezeti elemek megerősítési munkálatainak segítése. A laboratóriumi vizsgálatokhoz epoxi ragasztóval rögzített 8 mm átmérőjű menetesszárat alkalmaztunk, 50 mm rögzítési mélységgel. A menetes szárakat hőterhelés után kihűlt próbatestekbe ragasztottuk be. A beton próbatestek hőterhelése három
lépcsőben történt (200, 300, 400 ℃), a rögzítési mélységre vonatkozóan.
