中文摘要 | 高層集合住宅於台灣都會地區日益增加,對於建築樓板構造衝擊音的性能需求逐漸受到重視。為提升住宅音環境品質,我國建築技術規則建築設計施工編第46條之6於108年7月1日施行,而其他建築相關規範均已將樓板衝擊音列入評估標準。因此,本研究針對不同類型之減振材,包括發泡類減振材、聚酯纖維減振材以及自行開發之複合型橡膠粒墊減振材,並搭配常見之市售木地板參照CNS 15160-8進行樓板表面材衝擊音隔音性能實驗室量測,及參照CNS 8465-2計算其加權聲壓位準降低量ΔL_w。研究結果顯示,本研究發泡類減振材在硬度、密度、壓縮應力越低之條件下,其樓板衝擊音隔音性能越好。而複合型橡膠粒墊減振材應用結果顯示,由於橡膠材提供孔隙創造彈性,而聚酯纖維與玻璃棉由於纖維組織提供複合減振材較佳之結構系統,ΔL_w可達25 dB以上,具有良好之衝擊音隔音性能。 |
英文摘要 | In Taiwan, a lot of districts developed multi-story buildings. The Construction and Planning Agency has finished to revise the clauses of building regulation and to execute in 2016 (the clauses of floor impact sound are going to be executed in 2019).In this study, wefollowed CNS 15160-8 to execute the experiments of floor impact sound and calculated the result values by CNS 8465-2. We discussed the impact sound insulation performance of floor surface material which combined with foam, polyester and composite rubber materials. The results showed that, the impact sound insulation performance of foam damping material got better values with the lower hardness, density and Compression stress. The application of composite rubber damping material results show that, Rubber materials provide porosity to create elasticity, Polyester and glass wool provide a better structural system and ΔL_w value could up to 25 dB or more. |
