The invention discloses a heat-preservation sound-insulation high-crack-resistance floor slab layer which sequentially comprises a structural layer, a sound-insulation layer and a leveling layer from top to bottom. The structural layer comprises a prefabricated floor bottom plate layer and a lightweight aggregate concrete layer, and the concrete layer is poured on the prefabricated floor bottom plate layer. The composite floor slab layer composed of the prefabricated floor bottom plate layer and the lightweight aggregate concrete layer enables the floor slab layer to have good thermal insulation performance. The sound insulation layer and the surface layer protective mortar (leveling layer) enable the floor slab layer to have good sound insulation performance, and the weighting standardization impact sound pressure level index of the floor slab layer can be smaller than or equal to 70 dB. Compared with the prior art, the structure of the floor slab layer has the advantages that the thickness of the sound insulation layer can be greatly reduced, the indoor clear height of a building can be increased, the problem of floor slab surface layer cracking caused by compression deformation after the sound insulation layer is stressed can be solved, and the building quality is improved.
本发明公开一种保温隔声高抗裂楼板层，其从上到下依次包括结构层、隔声层、找平层；所述结构层包括预制楼底板层、轻骨料混凝土层，所述混凝土层浇筑于预制楼底板层上。本发明由预制楼底板层和轻骨料混凝土层构成的叠合楼板层使得楼板层具有良好的保温性能。隔声层与面层防护砂浆(找平层)使得楼板层具有良好的隔声性能，其计权标准化撞击声压级指标可≤70dB。并且本发明的楼板层的结构相较于现有技术，不仅可大幅的降低隔声层的厚度，有利于增加建筑物室内净高，并且还可减少隔声层受力后的压缩形变带来的楼板面层开裂的问题，提高建筑质量。
