Study on bending and tensile properties of thermal insulation wallboard with glass fiber sleeve tie-in

为研究玻璃纤维套筒拉结件保温墙板弯拉性能,设计弯拉试验并利用ABAQUS有限元软件建立弯拉有限元模型.对比分析试验与模拟结果的破坏形态和荷载-位移曲线.结果表明,玻璃纤维套筒拉结件保温墙板荷载达到5.25 kN时出现损伤,16.30 kN时达到极限荷载,试验与模拟结果的破坏形态相近.荷载-位移曲线规律一致,破坏时试验与模拟结果的极限承载力相对误差为10.4%,位移值相对误差为4.4%,试验与模拟结果相吻合,可为轻质夹芯保温墙板热阻断拉结件的实际应用提供依据.

In order to study the bending and tensile properties of glass fiber sleeve tie piece insulation wallboard,bending and tensile tests were designed and the bending and tensile finite element model was established using ABAQUS finite element software.The failure modes and load displacement curves of the test and simulation results are compared and analyzed.The results show that the thermal insulation wallboard of the glass fiber sleeve tie piece is damaged when the load reaches 5.25 kN,and reaches the ultimate load when the load reaches 16.30 kN.The failure patterns of the test and simulation results are similar.The law of load displacement curve is consistent,and the relative error between the test and simulation results is 10.4%,and the relative error of displacement value is 4.4%,The experimental results are in good agreement with the simulation results.which can provide a basis for the practical application of the thermal resistance breaking tie pieces of the lightweight sandwich insulation wallboard.
