Usage of cross linked polyethylene pad and nano silicon dioxide insulation felt: first, clean the ground to ensure no protrusions, and then lay the damping pad. The joints should be sealed neatly. If the edges and corners are not flush, they should be cut with a knife. The joints can be connected by lapping or butt joint, and the joints must be firmly bonded with special glue The joints shall be sealed with adhesive tape to prevent the cement mortar from infiltrating under the damping plate during the construction of the upper concrete, so that the sound bridge will fold up the edge of the sound insulation pad at the wall for four weeks again, and the floor sound insulation pad will be pasted on the wall with building glue points. The turnover height includes the total thickness of the concrete and the surface layer. The joints of the folded turnover shall also be pasted tightly with adhesive tape, and the laying thickness shall not be less than 40mm The C20 fine aggregate concrete shall be reinforced with reinforcing steel mesh in the concrete. The floor sound insulation and vibration damping pad is 5mm in common use. Pay attention that the steel mesh shall not pierce the sound insulation pad. The steel mesh shall ensure that the C20 fine aggregate concrete with a thickness of no less than 40 is laid in the middle and upper part of the concrete layer and shall not be replaced by cement mortar. The water content of C20 fine aggregate concrete shall not be too large, which is easy to cause cracking. When selecting the sound insulation and vibration damping board, it shall be determined We should choose the materials according to the needs, not only the price. Under different circumstances, all materials are different.
To achieve good results, we should make scientific and reasonable material selection:
1. The high density foam damping material can effectively absorb the vibration and noise of various frequencies. The impact sound of the floor can be improved as much as 1530db, which makes the impact sound insulation effect of the building floor exceed the requirements of the current green building standards and meet or better than the level of 5-star hotels.
2. Due to the large friction coefficient of the material surface, it is not easy to shift after pavement, which is conducive to the protection of wind and finished products; the product is thin in thickness and high in rigidity, which can significantly improve the foot feeling effect of various common low-density foam sound insulation pad products, and completely empty the hidden danger.
3. It is suitable for 30 ℃ - 120 ℃, and has no significant effect on the performance.
4. Inert products can resist the growth of mould or fungus. 5. The construction process is simple, the installation is fast, and the comprehensive cost is low.
