When the heat preservation and sound insulation board layer and the protection panel layer are compounded, the abutted seams of the heat preservation and sound insulation board layer and the abutted seams of the protection panel layer are staggered, and a certain blocking effect is achieved on sound conduction.
The assembled floor heat-insulation sound-insulation terrace system further comprises continuous and complete vertical sound-insulation sheets arranged at the joint of the heat-insulation sound-insulation composite board and the wall, and the distance h between the vertical sound-insulation sheets and the heat-insulation sound-insulation composite board is more than or equal to 10 mm.
Furthermore, the heat-preservation and sound-insulation composite boards are connected by adopting the grooves and the tongues, the groove and tongue connecting structure of the heat-preservation and sound-insulation composite boards is divided into a groove and tongue connecting structure of the heat-preservation and sound-insulation board layer and a groove and tongue connecting structure of the protection panel layer, and the upper end and the lower end of any groove and tongue connecting structure are spaced in the horizontal direction, so that a certain blocking effect on sound conduction is further achieved.
Furthermore, a gap exists between the tongue-and-groove connecting structure of the heat-preservation and sound-insulation board layer and the tongue-and-groove connecting structure of the protection panel layer in the horizontal direction, namely a slot or a hook slot is formed between the two tongue-and-groove connecting structures.
Furthermore, the tongue-and-groove connecting structures between the heat-preservation and sound-insulation composite boards are positioned on four sides of the heat-preservation and sound-insulation composite boards to be connected, and the tongue-and-groove connecting structures can adopt structures such as slot type, inclined slot type, hook slot type or dovetail slot type.

The sealant is made of polyurethane or silicone flexible material, has certain elastic deformation, and can prevent the cracking of joints such as plate seams and the like.
And light bonding leveling materials are coated on the surface layer at the slab joint of the tongue-and-groove connecting structure between the heat-preservation and sound-insulation composite slabs.
Furthermore, the heat preservation sound insulation board layer adopt XPS board, EPS board or graphite polyphenyl board, thickness is 1.5~2.5 cm.
Further, the protective panel layer is a mortar finished board with a texture model on one surface, and the mortar finished board is formed by pouring mortar into a flat plate mould with a waveform or stripe shape, and the thickness of the mortar finished board is 2-3 cm.
Furthermore, the heat preservation sound insulation board layer is bonded on the non-texture-shaped surface of the protection surface board layer.
Further, the protective panel layer comprises the following raw materials in percentage by mass:
23 to 35 percent of Portland cement,
2 to 3 percent of sulphoaluminate cement,
0 to 5 percent of fly ash,
1 to 5 percent of mineral powder,
0 to 3 percent of silica fume,
0 to 1.5 percent of anhydrite,
0 to 0.5 percent of calcium oxide expanding agent,
50 to 62 percent of sand,

the rubber particles are spheres with certain elasticity and are uniformly distributed in the binder, and when impact sound is transmitted through media such as cement and sand, the sound wave can cause the rubber particles to generate vibration friction, so that sound transmission energy is attenuated, and the sound transmission is blocked.
The light-weight bonding leveling material is formed by mutually combining 5 different light-weight aggregates, and plays a role in assisting sound insulation for the heat-insulation and sound-insulation composite board by combining two principles of hollow isolated sound conduction and energy consumption during sound wave conduction.
The light aggregate is applied to the light bonding leveling material by utilizing the structural characteristics of the light aggregate, and has a barrier effect on sound conduction.
The light bonded leveling material is combined with the tongue-and-groove structure of the heat-insulation and sound-insulation composite board, so that the weak link of heat insulation and sound insulation at the board gap can be thoroughly solved, and the heat insulation and sound insulation performance of the whole heat-insulation and sound insulation system is optimal.

The heat-insulation and sound-insulation composite board does not need on-site maintenance, the contraction of the protective panel is small, the strength is high, and the elastic expansion joint formed by smearing the sealant at the board joint is prevented from cracking. The light bonding leveling material has high bonding strength and has the functions of assisting in heat preservation and sound insulation, so that the whole system is safe and reliable. The thickness of the whole composite board heat-insulating and sound-insulating system is thinner than that of a floating floor heat-insulating and sound-insulating system, so that the load of a floor structure layer is reduced, and the indoor space is promoted.
