Abstract:
Through laboratory comparison tests on organic and inorganic chemical anchor bolts under the conditions of different fire temperature, cooling method, and standing time, the high temperature mechanical performance of organic and inorganic chemical anchor bolts was studied. The results show that: after being effected by fire high temperature, the uplift bearing capacity of chemical anchor bolts decreased in a whole series, as the temperature gradually increasing, the anti-pull bearing capacity of organic anchor bolt has a significant reduction, the uplift bearing capacity of inorganic chemical anchor bolt is reduced at the beginning, then shows a slight rebound, at last is significantly reduced; the extreme temperatures of anchor bolt work are 170 ℃ and 450 ℃, the fire-resistant limit temperatures are 300 ℃ and 700 ℃ for organic and inorganic chemical anchor bolts. 4 figs, 10 refs.
