Abstract

L'invention concerne une structure de support de sol pour un bâtiment présentant un corps en béton constitué d'une construction régulière de poutres, une dalle de sol étant reliée à la surface supérieure d'une poutre, dans laquelle un bruit de vibrations parcourant la structure de sol se propage de manière distributive jusqu'au mur de corps, par le biais d'une poutre transversale pour augmenter l'effet d'isolation sonore. De plus, la structure de sol peut être étayée de manière stable, et l'épaisseur de la dalle de sol peut être rendue inférieure à celle de l'état de la technique, ce qui permet d'augmenter la hauteur efficace de l'espace de vie, de réduire le poids du corps en béton pour améliorer la résistance aux tremblements de terre et la commande des vibrations, et de réduire le coût du bâtiment lui-même. A cette fin, une pluralité de poutres transversales (5) constituant la structure de sol (Fr) d'un bâtiment, sont espacées, côte-à-côte dans un plan, un espace (D1) étant défini entre une poutre transversale et une dalle de sol (Sf), et sont étayées à leurs extrémités opposées par le biais d'un mur de corps vertical (2), un espace (D2) étant défini entre l'extrémité et le mur de corps vertical (2).
