Abstract:
1. A sound-insulating and vibration-isolating rubber pad used for a floor consisting of flooring boards which are installed to have a certain height from an indoor concrete floor, which has an irregular flatness, comprising: a lower pad comprising a lower pad body which directly supports a lower surface of a lower water-proof plywood piece in a state in which the lower pad body is inserted in an insertion hole formed in the lower water-proof plywood piece and is formed at a thickness of 5 to 50 mm so as to absorb vibration and shock applied from a floor to the concrete floor, wherein an upper surface of the lower pad body is formed in any one chosen among square, rectangular, circular, triangular, five-angled to twelve-angled, and oval shapes, a lower pad protrusion which is formed in the center of an upper surface of the lower pad body to be inserted into the insertion hole, an insertion recess which is formed in the center of an upper surface of the lower pad protrusion, and a latching recess which is formed inside the insertion recess, wherein the material of the lower pad is any one chosen among a raw rubber, a synthetic rubber, and a natural rubber; and an upper pad comprising an upper pad body which is formed to be inserted into the insertion recess of the lower pad as well as the insertion hole in a state in which an upper surface of the upper pad fits an upper surface of a receiving space, wherein an upper surface of the upper pad body is formed in any one chosen among square, rectangular, circular, triangular, five-angled to twelve-angled, and oval shapes, an upper pad protrusion which is formed in the center of a lower surface of the upper pad body to be inserted into the lower pad protrusion, and a protruded insert which is formed in an end of the upper pad protrusion, wherein the material of the upper pad is any one chosen among a raw rubber, a synthetic rubber, a natural rubber, and a synthetic resin.
