外墙外保温系统保温层与结构层的粘结强度研究

Study on the Bond Strength of the Thermal Insulation Layer and the Structure Layer in the Exterior Wall's External Thermal Insulation System

在外墙外保温系统中,保温层与结构层的粘结强度是保证工程质量的重要环节。对常用的3种保温材料的性能进行了比较。就保温板的粘结方式、现场拉拔强度试验、提高粘结强度的措施以及现场检验的评定方法等进行了探讨。

In the exterior wall＇s external thermal insulation system, the bond strength of the thermal insulation Layer and the structure Layer is an essential part to ensure the quality of a construction project. In this paper, the performances of the three kinds of often-used thermal insulation materials are compared and such matters as the bonding method of the board insulasion, the in-situ test of the tensile- and- pullout strength, the measures to improve the bond strength and the assessing method of the in-situ test are discussed as well.
