Problems solved by technology

[0002] With the development of society, there are more and more new civil buildings, and people have higher and higher requirements for sound insulation and heat insulation between floors. However, the current floor sound insulation and heat insulation systems generally adopt floating structures. This structure is organic The sound insulation and thermal insulation materials are placed on the floor. After the floor is under load or trampled for a long time after forming, a large number of cracks may appear. Moreover, the construction of the traditional floating structure is relatively complicated, the cost is high, the quality is difficult to guarantee, and it will greatly increase the cost. The ground height of the floor is raised, and under the environment where the whole society advocates energy saving, environmental protection and quality improvement, the sound insulation system of this structure cannot meet the requirements of consumers
[0003] In the prior art, the structure of floating floor slab generally adopts the structure of floor base, heat insulation and sound insulation cushion, fine stone concrete protective layer, steel wire mesh and vertical sound insulation sheet arranged sequentially from bottom to top. Sound insulation effect, but in the actual use process, there are still problems that cracks will appear on the floor surface and the ground height of the floor is too high, which cannot meet the needs of consumers

Abstract

The sound insulation and heat preservation system of the floor slab comprises a reinforced concrete floor slab, a sound insulation and heat preservation plate is fixedly installed below the reinforced concrete floor slab through bolts, a decorative surface layer is laid above the reinforced concrete floor slab, and the thickness of the sound insulation and heat preservation plate is 20-40 mm. The construction method comprises the following construction steps: firstly, erecting reinforcing steel bars on a building template and pouring concrete, and forming the reinforced concrete floor after the concrete is solidified; bolt holes are evenly formed in the lower portion of the reinforced concrete floor, a sound insulation and heat preservation plate is pasted to the lower surface of the reinforced concrete floor through an adhesive, and bolts are matched with the bolt holes to fixedly connect the sound insulation and heat preservation plate with the reinforced concrete floor; and finally, a decorative surface layer is laid on the reinforced concrete floor slab. The sound insulation and heat preservation layer is effectively prevented from cracking, and the height above the reinforced concrete floor is reduced; the assembly of the sound insulation and heat preservation plate is facilitated, construction is simple and convenient, the labor and material cost is reduced, and the engineering efficiency and quality are improved.
