建築物外牆瓷磚剝落，就像在台灣一樣，已經在世界各地造成許多的意外傷害事件。瓷磚拉拔試驗可應用於不同張貼工法黏著強度的試驗驗證；本研究主要是運用CNS 12611抗拉接著強度試驗法，比較有振動工具之密貼工法及沒有振動工具之壓貼工法(含壓1公斤重錘及不壓重錘)，在使用不同背溝型式瓷磚張貼時，黏著強度的差異性。試驗結果顯示：密貼工法抗拉接著強度之平均值，使用有燕尾狀背溝射出磚張貼時，為13.0kg/cm2；使用沒有燕尾狀背溝粉壓磚張貼時，為13.3kg/cm2。壓重錘之壓貼工法，使用射出磚張貼時，為11.1kg/cm2；使用粉壓磚張貼時，為9.7kg/cm2。沒有壓重錘之壓貼工法，使用射出磚張貼時，為9.1kg/cm2；使用粉壓磚為8.1kg/cm2。研究結果顯示：使用密貼工法之抗拉接著強度明顯優於壓貼工法；使用射出磚張貼時之抗拉接著強度優於粉壓磚。

Hazardous accidents caused by exterior wall tile peeling were reported periodically in Taiwan as well as from many other countries. Pull-off tests were applied in this research to reexamine the adhesive performances for different placing methods. Extruded and dust-pressed tiles were used for both methods as well. The average tensile adhesion strength with the electrical impacting tool of extruded and dust-pressed tiles were measured at 13.0kgf/cm2 and 13.3kgf/cm2. The average tensile adhesion strength of pressure application with additional 1kg metal ingot pressed down for extruded and dust-pressed tiles were measured at 11.1kgf/cm2 and 9.7kgf/cm2. Without the 1kg additional press down weight, the average tensile adhesion strength for extruded and dust-pressed tiles were measured at 9.1kgf/cm2 and 8.1kgf/cm2. Results show that placing method using electrical vibrator outperforms the other one. For pressure application placing method, extruded tile outperforms the dust-pressed tile.
