    摘要: The floor structure has a base layer fastened to floor joists, a resilient layer laid over the base layer, and a top layer mounted over the resilient layer. The top layer has a stiffness that is greater than a stiffness of the base layer. The top layer is fastened to the base layer by wood screws that are placed substantially along a median between two adjacent floor joists. Each screw has a threaded portion extending simultaneously in both the top and the base layers. The installation of screws through the top and the base layers causes a backlash in the advance of the screws upon entering the base layer, thereby causing the occurrence of a larger gap between the layers as compared with an installation using nails. The larger gap relaxes a pressure on the foam layer and reduces the transmission of sound energy to the joists.
