4', 24'... are fixed, and these mounting members 24', 2
4'..., as shown in Fig. 8, the stiffening beam 2' and the lower chord member 25' disposed on the lower surface of the frame members 11', 11'... of the floor panels 1', 1'... By linking them together, each of the floor panels 1', 1', .
〈発明の効果〉
以上の様な防振施工法においては、床パネル自
体の剛性が高まる丈でなく、各床パネルによつて
構成される床面の剛性が高くなる為床全体が高い
防振性能を示すことになる。<Effects of the invention> In the above-mentioned vibration isolation construction method, the height of the floor panel itself does not increase the rigidity, but the rigidity of the floor surface constituted by each floor panel increases, so the entire floor has high vibration isolation. It will show the performance.
しかも床パネルを構成する枠材と直交して補剛
梁が設けられるので、所謂床荷重が枠材（根太）
方向と補剛梁方向の二方向に伝達することも可能
となり、従来の単方向の荷重伝達の構造と比較し
て床の撓みや振動も小さくなる。 Moreover, since the stiffening beams are installed perpendicular to the frame materials that make up the floor panel, the so-called floor load is transferred to the frame materials (joists).
It is also possible to transmit load in two directions: the direction of the load and the direction of the stiffening beam, and floor deflection and vibration are also reduced compared to conventional unidirectional load transmission structures.
更に、床パネル内に取付けた補剛梁の高さを、
床パネル厚よりも小さくしておけば、補剛梁は床
パネルの外方へ突出することなく完全に内蔵され
た形となる。よつて各床パネルの搬送、施工に際
し、極めて良好なものとなる。 Furthermore, the height of the stiffening beam installed inside the floor panel is
If it is made smaller than the floor panel thickness, the stiffening beam will be completely built into the floor panel without protruding outward. Therefore, the transportation and construction of each floor panel becomes extremely convenient.
すなわち、本発明の建物床の防振施工法は、床
