Gypsum sound insulation system for floor sound insulation and application of gypsum sound insulation system

Abstract

The invention discloses a gypsum sound insulation system for floor sound insulation and an application of the gypsum sound insulation system. The gypsum mortar sound insulation system is composed of a high-strength gypsum self-leveling mortar surface layer and a low-strength cushion layer, and the 28d absolute dry compressive strength of a cushion layer material does not exceed 80% of the 28d absolute dry compressive strength of a surface layer material. The thickness of the surface layer is 10-25mm, the thickness of the cushion layer is 10-25mm, and the total thickness of the surface layer and the cushion layer is less than 40mm. According to the gypsum sound insulation system for floor sound insulation and the application of the gypsum sound insulation system, the gypsum mortar sound insulation system is arranged on a floor slab, and a decorative layer is arranged on the gypsum mortar sound insulation system. By utilizing double-layer mortar structures with different strengths, the leveling layer has a better sound insulation effect. When ceramic tiles are used as the decorative layer, the sound insulation index can reach more than 10dB, the use requirements of common residences can be met, an elastic body sound insulation layer does not need to be additionally arranged, and the construction procedures and the project cost are reduced.

Description

technical field [0001] The invention relates to the technical field of sound insulation, in particular to a gypsum sound insulation system for floor sound insulation and its application. Background technique [0002] In recent years, with the rapid development of high-rise buildings, the problem of floor sound insulation has become increasingly prominent. The poor sound insulation performance of floor slabs not only affects the living experience, but also affects the relationship between neighbors. It is urgent to solve the sound insulation problem of floor slabs. [0003] At present, the sound insulation of floors mainly adopts the technology of floating sound insulation floors. For the structure of floating floors, see figure 1 . Specifically, from bottom to top, it includes structural layer (reinforced concrete floor)→elastic damping layer (elastic material layer)→floating plate layer (fine stone concrete layer with steel wire mesh). Currently, the commonly used elastic ...

AI Technical Summary

Problems solved by technology

[0008] (1) A separate elastomer sound insulation layer is added, which increases the construction process and project cost

[0009] (2) Due to the low strength of the above-mentioned elastomer materials, a thicker leveling layer must be used. In the case of a fixed floor height, the net height of the room is reduced, which affects the living experience

[0010] (3) Because it contains organic components, its combustion performance is usually Class B, the material detection is complicated, and there is a risk of fire during construction and use

Therefore, it is impossible to achieve a good sound insulation effect only by using the existing leveling layer technology
