description The invention belongs to the technical field of scientific experiments of building materials, and particularly relates to an experimental device and method for measuring the heat conductivity coefficient of the building materials in a service state. The experimental device comprises a fixing support, a direct-current power supply and a temperature data acquisition system, and a supporting plate, a heat insulation plate, a first contrast sample, a first flake electric heater, a first thermocouple group, a first pressed sample, a second thermocouple group, a second pressed sample, a second flake electric heater, a second contrast sample and a heat shield are sequentially placed on the fixing support from top to bottom, wherein the direct-current power supply is connected with the first flake electric heater and the second flake electric heater, and the temperature data acquisition system is connected with the first thermocouple group and the second thermocouple group. By the operation method and data acquired b
