Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a slab fixing structure in which a vibration damper is used in a proper place with little fluctuation in the vertical direction of a fixing part, and thereby the transmission of sound can be made difficult between upper and lower floors while reducing weight by thinning the thickness of a precast slab.SOLUTION: This slab fixing structure is applied when fixed to a beam assembly 3 constituted of two girders 1 being parallel to each other and two small beams 2 disposed perpendicular to the girders 1 between these two girders 1 while overlapping 4-sides of the end edge of a precast slab 4 of a planar shape square on the two girders 1 and two small beams 2, respectively. A vibration damper 11 is provided between the two girders 1 and two small beams 2 and the precast slab 4. The two girders 1 and two small beams 2 are joined with the precast slab 4 on neutral axes O1, O2 of the precast slab 4.SELECTED DRAWING: Figure 1
【課題】 固定部の上下方向の変動が少ない適正な箇所に防振材を使用することで、プレキャストスラブの厚さを薄くして軽量化を図りつつ、上下階間で音が伝わり難くすることが可能なスラブの固定構造を提供する。【解決手段】 このスラブの固定構造は、互いに平行な2本の大梁1と、これら2本の大梁1間に大梁1に対し直交して配置された2本の小梁2とで構成される梁組3に、平面形状方形のプレキャストスラブ4の4辺の端縁部を2本の大梁1および2本の小梁2の上にそれぞれ重なる状態で固定する場合に適用される。2本の大梁1および2本の小梁2とプレキャストスラブ4との間に、防振材11を有する。プレキャストスラブ4の中立軸心O1,O2上で、2本の大梁1および2本の小梁2とプレキャストスラブ4とが接合されている。【選択図】 図1 |
