聚脲弹性体喷涂钢筋混凝土构件抗爆性能研究

Study on Explosion Resistance of Reinforced Concrete Member Sprayed with Polyurea Elastomer

聚脲弹性体可以提高墙体结构的抗爆能力,降低破坏碎片的产生。本文通过爆炸实验研究聚脲弹性体加固厚度和加固方式改变对喷涂聚脲弹性体加固钢筋混凝土构件的抗爆性能的影响,研究发现双面加固聚脲弹性体的钢筋混凝土构件,其迎爆面能降低冲击波超压对结构的破坏,背爆面加固可降低卸载波对结构破坏,迎爆面和背爆面增强墙体抗剪、抗弯能力,减弱墙体凹曲变形程度。

Polyurea elastomer can improve the anti-explosion ability of wall structure and reduce the generation of destructive debris.Experimental study based on the explosive polyurea elastomer reinforced thickness and reinforcement method of spray polyurea elastomer reinforced concrete member antiknock performance,the study found that the double reinforcement polyurea elastomer reinforced concrete members,and welcomed the surfaces can reduce the damage to the structure of the shock wave overpressure,and back surfaces reinforcement can reduce the discharge wave,the results meet the blast and back wall shear,bending capacity,less wall concave deformation degree.
