This paper details the ability of the tile debonding diagnostic device to detect artificially debonded areas on twelve exterior-tile wall specimens, using a detection parameter proposed in the previous paper. The device has an impact force sensor and four microphones and outputs detection parameter RAF for each microphone. The maximum value of RAF at the four microphones was defined as RAF-max. A threshold value of RAF-max was set and the results of detection of debonding were displayed on figures of the specimens. As a result, the effectiveness of the device and the detection parameter was verified.

This paper details the ability of a tile‐debonding diagnostic device to detect artificially debonded areas on 12 exterior‐tile wall specimens, using a detection parameter proposed in a previous paper. The device has an impact force sensor and four microphones and outputs detection parameter RAF for each microphone. The maximum value of RAF at the four microphones was defined as RAF‐max. A threshold value of RAF‐max was set, and the results of detection of debonding were displayed on the figures of the specimens. Consequently, the effectiveness of the device and detection parameter was verified.

We developed a hybrid SWP with organic and inorganic heat insulating materials as the core material and verified the performance of fire resistance and mechanics during the development process. By using both inorganic and organic materials together, it exhibits better fire resistance than organic materials alone. In particular, the specifications using fiber-reinforced plaster board plate, which was superior to the specifications using rockwool in terms of mechanics, also showed excellent fire resistance in the ISO 13784-1 test. *1 ㈱フジタ技術センター 主任研究員・博士(学術) (〒 243-0125 神奈川県厚木市小野 2025-1) *2 東京大学大学院工学系研究科建築学専攻 教授・博士(工学)
