This creation is related to the field of sound insulation technology for floors, especially a sound insulation structure applied to floors to reduce impact noise.

Today's collective residential buildings mostly adopt reinforced concrete (RC) or steel-reinforced concrete (SRC) structures. The floors are mainly composed of steel bars and concrete or steel plates and concrete, which have no sound insulation effect. Therefore, human actions in the upper space, For example, when walking, jumping, moving objects or falling objects, when there is an impact on the floor, the shock wave will be transmitted to the lower space through the concrete of the floor, causing brain-human noise problems.

There are many sound insulation structure technologies in the known technology, but the sound insulation technology of the floor is mostly imported from Japan, which is expensive to build and often leads to excessive thickness of the floor, such as the known hollow floor structure, and the construction procedure of the hollow floor structure is complicated , if the construction is improper, such as the polystyrene ball is not fixed, the pipeline is not emptied, and it is placed in the wrong or improper position, it will cause the concrete of some hollow slabs to be too thin, which will have a negative impact on the earthquake resistance of the building.
