Detailed Description
The present invention will be further explained with reference to the following detailed description and accompanying drawings.
As shown in fig. 1, the sound insulation and heat preservation pad 100 for a floor slab, the sound insulation and heat preservation pad 100 sequentially comprises a sound insulation layer 110, a damping layer 120 and a vibration damping layer 130 from top to bottom; the sound insulation layer 110 is made of high-density foamed rubber plastic materials, the thickness of the sound insulation layer 110 is 3-8mm, and the foaming multiplying power is 10-20 times; the damping layer 120 is an adhesive with a damping function, and the thickness of the damping layer 120 is 0.2-0.5 mm; the damping layer 130 is a high-density foamed rubber plastic material or felt with a plurality of structural holes 131, the thickness of the damping layer 130 is 3-8mm, and the foaming multiplying power is 10-25 times. The sound-proof thermal insulation pad 100 can be directly laid between the floor slab and the concrete of the protective layer (not shown in the figure) or between the vertical walls (not shown in the figure). The sound insulation layer 110 and the vibration reduction layer 130 with different thicknesses can meet the sound insulation and heat preservation requirements of different places.
The damping layer 130 provided with the structural holes 132 has a good sound blocking effect on impact sound in the whole frequency range, and can effectively isolate impact noise and air transmission noise.
In addition, a wire mesh reinforcing layer (not shown) is arranged between the sound insulation and heat preservation cushion 100 and the protective layer concrete (not shown). The metal wire mesh reinforcing layer (not shown in the figure) is a steel wire mesh, the side length of the mesh is 30-75mm, and the diameter of the steel wire is 2-3 mm. Therefore, the cushion layer can be prevented from being deformed greatly under the action of the self weight of the concrete layer and the indoor load, and the concrete protective layer is prevented from cracking.
The sound insulation layer 110, the damping layer 120 and the vibration damping layer 130 are hermetically connected by arranging a plurality of vibration damping strips 140 on the side surfaces 111, 121 and 131, specifically, the vibration damping strips are hermetically bonded to the side surfaces 111, 121 and 131 of the sound insulation layer 110, the damping layer 120 and the vibration damping layer 130 by using a sealant (the position of the side surfaces is not limited to the position shown in the figure, and includes any side surface).
