摘　　要：为提高外墙外保温系统中保温板与基层的粘结强度以抵抗整个系统的脱落破坏,设计相关试验研究不同粘结方式、不同粘结面积、不同粘结厚度及辅以不同数量锚栓联合固定对膨胀聚苯乙烯板(EPS保温板)与基层墙体间的抗拉和抗剪切强度的影响情况。研究结果表明,EPS板在两种大小尺寸下的最佳粘结厚度均为4 mm,5种粘结方式中满粘强度最高,综合效益最好的是点框粘结,其强度能达到满粘的90%,采用较好的点框粘结进行双面粘结并辅以5个锚栓形成的综合粘结方式强度最好。In order to improve the strength of bonding between the insulation board and the wall to prevent the destruction of the entire exterior insulation system,experiments to study the influence of different way,different area and different thickness of bonding and different n u mber of anchors on the tensile and shear strength of bonding between the expanded polystyrene （ EPS ） board and the wall were carried out. T he results show that the optimum bonding thickness for EPS boardof both sizes is 4 mm . The optimum way to achieve the highest strength is “full bonding”,while the most efficient way is “ point-frame bonding”,strength of which can reach 9 0 % of the strength of the “full bonding”. The best bonding strength can be obtained by adopting the “ point-frame bonding” and “ double-side bonding” with 5 anchors.
