多功能木構造非承重牆系統之設計開發
Design and Development of Multi-functional Wooden Structure Non-load-bearing Wall System
摘要
由於木構造非承重牆結構為由外層、面板材及填充材等複合組成，因此，複合層材料之種類及性質與排列等因素均會影響成品之各項耐火及隔音性能。本研究之目的為探討設計規劃七種不同材料與構造工法之試體，評估可通過我國建築法規防火時效一小時、隔熱性（非曝火面溫度低於140℃）及隔音性能至少50 dB等多功能之木構造非承重外牆。首先於實驗室以小型加熱試驗爐進行燃燒試驗後，選擇可通過建築法規之木構造非承重牆構造工法，各項耐火性能因子最佳條件者，再進行隔音性能之測定。期提供相關業者作為未來大尺寸試體製造之參考。七種試體設計全數可通過CNS 12514-1一般要求事項之阻熱性與遮焰性標準，及符合防火時效一小時。雖之如此，構成複合材料之單材热傳導係數、密度及試體結構之層間材、副層間材、厚度及有無木柱配置等因子均會影響試體質量損失率、遮焰性、阻熱性、炭化程度及非曝火面溫度等之差異。選擇厚度125 mm（Type 4-1）及175 mm（Type 4-2）兩種試體進行隔音性能測定。結果顯示，厚度125 mm試體Type 4-1，隔音性能為49 dB，未能通過法規標準，而試體厚度175 mm試體Type 4-2，者可達52 dB。綜合結果顯示，未來選擇牆面體之耐燃、隔熱及隔音性能，建議以Type 4-2試體構成設計為宜。

Since the wooden non-load-bearing wall structure is composed of the outer layer, the sub-layer and the filler material, hence, the types, characteristic and arrangement of the composite layer materials will affect the fire endurance and sound insulation properties of the finished product. The purpose of this study was to explore the design and planning of seven different materials and structure methods, and evaluate which can pass the fire rating one hour, heat insulation (non-exposed surface temperature less than 140℃) and sound insulation performance of at least 50 dB, etc. The wooden structure of the multifunctional system is a non-load-bearing walls. Firstly, after the combustion test is carried out in the laboratory with a small heating test furnace, the wooden structure non-load-bearing wall that can pass the building regulations is selected, and the fire endurance factor is the best, and then the sound insulation performance is measured. It is expected to provide relevant industry as a reference for the manufacture of large-scale specimens in the future. The seven specimens designs can pass the thermal insulation and fire integrity standards of CNS 12514-1 general requirements, and meet the fire rating for one hour. Nevertheless, the thermal conductivity, and density of the single material constituting the composite material and the interlayer material, sub-layer material, thickness, and wooden pillar of the test specimen structure will affect the performance difference as mass loss rate, thermal insulation, heat resistance, carbonization degree and non-exposed surface temperature. Two specimens with a thickness of 125 mm (Type 4-1) and 175 mm (Type 4-2) were selected for sound insulation performance measurement. The experimental results showed that Type 4-1 with a thickness of 125 mm had a sound insulation performance of 49 dB, which failed to pass the regulatory standards, while Type 4-2 with a thickness of 175 mm could reach 52 dB. In summary, in the future, when choosing the fire endurance, thermal insulation and sound insulation performance of the wall specimen, it is recommended to use the Type 4-2 test specimen composition design.
