CONSTRUCTION METHOD AND DESIGN METHOD OF SOUND INSULATION BOUNDARY FLOOR STRUCTURE, AND SOUND INSULATION BOUNDARY FLOOR STRUCTURE OF BUILDING
To provide a method of constructing and designing a sound insulation boundary floor structure capable of surely securing boundary floor sound insulation performance against weight impact sound when the sound insulation performance of a boundary floor is improved by the structure in which a floating floor layer is disposed above a floor slab of a building, and a sound insulation boundary floor structure of the building.SOLUTION: In a sound insulation boundary floor structure to improve sound insulation performance in a floor slab 10 by disposing a floating floor layer 13 via vibration-isolating bearings 12, dimensions, density and bending rigidity are determined so that a natural frequency f of small-divided floor plates 13a - 13c of a floor plate constituting the floating floor layer satisfies a specific calculation formula, and the small-divided floor plates having the determined dimensions, density and bending rigidity are installed. However, assuming that each dimension of the longitudinal length, lateral length, and thickness of the small-divided floor plate is a, b and h (m), and Young's modulus of the floor plate material is E (N/m) and density is ρ (kg/m), the natural frequency (minimum value) of the small-divided floor plate is given by a specific calculation formula.SELECTED DRAWING: Figure 1
【課題】建物の床スラブの上部に浮床層を配置した構造により界床での遮音性向上を図る場合に、重量衝撃音に対する界床遮音性能を確実に確保可能な遮音界床構造の構築方法、設計方法および建物の遮音界床構造。【解決手段】床スラブ１０の上部に防振支承１２を介して浮床層１３を配置することで界床での遮音性向上を図るための遮音界床構造において、浮床層を構成する床板の小割床板１３ａ〜１３ｃの固有振動数ｆが特定の計算式を満たすように寸法・密度・曲げ剛性を決定し、設置されるものとする。ただし、小割床板の縦長さ、横長さ、厚さの各寸法をａ、ｂ、ｈ（ｍ）とし、床板材質のヤング率をＥ（N/m2）、密度をρ（kg/m3）とすると、小割床板の固有振動数（最小値）は特定の計算式で与えられる。【選択図】図１
