FLOOR STRUCTURE AND VISCOELASTIC BODY FOR USE IN THE SAME

摘要

PROBLEM TO BE SOLVED: To enable a floor impact sound to be sufficiently reduced even when a viscoelastic body is thin, and enable sufficient securement of load capacity of a floor.SOLUTION: In a floor structure which is arranged between a floor joist 12 and a beam 20 and which comprises a viscoelastic body 30 with vibration insulating properties, four or more protrusive streak parts 32 and 33 extending in the same direction as the lengthwise direction of the beam 20 are formed on one of top and under surfaces of the viscoelastic body 30.SELECTED DRAWING: Figure 6
