摘　　要：为了研究一种全封闭型防火保温装饰一体化板的基本力学性能,设计了板的粘结强度、抗压强度、抗折强度以及平面外承载力强度试验。结果表明:在满足基本工艺要求的情况下,复合保温板的粘结强度较好;其抗折强度随着保温板厚度增大而增大;在平面外荷载作用下,其破坏形态具有明显脆性。并且通过一个算例表明,其抗压强度和抗折强度能满足全国范围内风压不大于1.0 kN/m2、离地高度20m以下,设防烈度不高于8度(0.30g)的建筑外墙安全性能要求。The mechanical properties are studied for a new full closing fire prevention board with energy-saving and decorating. According to the structure of the board and the loads after insolated, the relevant tests are design, including the bond strength, the plane bearing capacity, the compressive strength and the breaking strength. The experimental phenomena, the characteristics of failure and the capacities of the board are analyzed. Based on the national standards, the safety requirements of the external walls can be satisfied.
