我國建築技術規則對於分間牆的隔音與防火性能皆有要求，建築中特定區劃甚至需要同時具有兩項性能。但市面上的隔音分間牆與防火分間牆在施工方法上卻有些許不同，在工地施作現場的施工法選用將會對性能的判定造成疑慮。因此本研究目的即是使用同一套施工方法進行分間牆建置，並進行性能測試以找出同時具有隔音與防火性能的分間牆。輕鋼架分間牆可分為面板材料、骨架材料、內部填充材料及填縫材料。本研究針對建築技術規則中的隔音分間牆材料規格，與通過隔音測試或防火測試的分間牆材料規格進行比較，發現在板材總面密度及填充材厚度兩項規格上，法規的規格與市售的分間牆規格相比，有較高的比例是法規的規格遠高於市售分間牆的規格。此現象說明法規所提供的不經檢測直接宣告隔音量的方法，尚須更多的討論及研究作輔助，以利法規的執行與改善。本研究參考建築技術規則中，隔音分間牆的材料規格作為實驗試體的使用材料，並依據中華民國國家標準之規定進行防火測試。在單層矽酸鈣板的分間牆防火測試，了解曝火面板材的完整性，對於阻熱性能有著極為顯著的功效。雙層矽酸鈣板的分間牆防火測試則說明板材層數對於防火時效有直接的影響。而加強雙層矽酸鈣板的分間牆防火測試，發現加強橫撐提供立柱局部結構的穩定，雖然對於防火時效無直接的影響，但是立柱結構的維持卻會間接影響牆體的防火時效。

Building Technical Regulations have requirements for the sound insulation and fire resistance of partition walls, and certain areas in a building need to have both properties. However, the construction methods of soundproof partition walls and fireproof partition walls on the market are slightly different. The choice of construction method used on the construction site will cause doubts about the performance judgment. Therefore, the purpose of this study is to use the same construction method to build partition walls and conduct performance tests to find the partition walls that have both sound insulation and fire resistance performance. The light steel frame partition wall can divide into panel material, skeleton material, insulation material, and caulk material. This study compares the material specifications of soundproof partition walls in the regulations with the material specifications of partition walls that pass the sound insulation test or fire test. It was found that in terms of the total area density of the board and the insulation thickness, the regulatory specifications are much higher than the commercially available partition wall specifications. This phenomenon shows that the method provided by the regulations to directly declare the amount of sound insulation without testing requires more discussion and research to assist in order to facilitate the implementation and improvement of the regulations. This study refers to the material specifications of the sound insulation partition wall in the Building Technical Regulations as the materials used for the test specimen. It conducts fire tests according to the provisions of the Chinese National Standards. In the single-layer partition wall fire test, the exposed surface board's integrity has a very significant effect on insulation performance. The results of the double-layer partition wall fire test show that the number of board layers has a direct effect on the fire rate. While from the reinforced double-layer partition wall fire test, this study found that the reinforced rail provides stability of the local structure of the stud. Although there is no direct effect on the fire rate, the stud structure's maintenance will indirectly affect the fire rate of the wall.
