Description

Sound-insulating and heat-insulating composite floor slab

Technical Field

The utility model belongs to a building structure, specifically speaking especially relates to a sound insulation and heat insulation composite floor.

Background

With the continuous development of city construction and the increasing living standard of people, the requirements of people on living environment are higher and higher. The method changes from the interest of simple house type and area to the interest of residential heat environment, acoustic environment and light environment. In recent years, there have been more and more contradictions due to noise interference, and a social problem has been caused by a contradiction due to sudden noise generated by a necessary activity of people in the same building. At present, the sound insulation problem of concrete ground can be solved by adopting a 'floating ground' method, namely 1 layer of damping ground mat is paved on a structural floor slab, and then concrete is poured on the damping ground mat. In addition, the sound insulation of the floor slab is greatly improved by paving the wood floor on the concrete floor, and the solid wood floor and the composite floor have good impact sound insulation effect, but the construction is complicated. With the increasing adoption of air conditioners and heating in house buildings, the requirement for heat insulation of the floor slab is higher and higher.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a sound insulation and heat insulation composite floor to overcome prior art in the floor can not satisfy the defect that the resident sound insulation of present stage required that insulates against heat.

The utility model discloses an adopt following technical scheme to realize:

the utility model provides a sound insulation and heat insulation composite floor, includes cast-in-place concrete layer, dampproof course, first gypsum board layer, first filling layer, first profiled steel sheet, precast concrete layer, stress dispersion layer and second gypsum board layer, cast-in-place concrete layer, dampproof course, first gypsum board layer, first profiled steel sheet, precast concrete layer, stress dispersion layer and second gypsum board layer are laminated together in proper order from the top down, first filling layer is filled in first profiled steel sheet space.

Furthermore, sound insulation and heat insulation composite floor still includes second profiled steel sheet, second filling layer, third gypsum board layer, second profiled steel sheet, third gypsum board layer stack in proper order in second gypsum board layer below, the second filling layer is filled in the second profiled steel sheet space.

Further, first filling layer and second filling layer are rock wool board.

Furthermore, rock wool boards which are stacked up and down in two different densities are filled in the first filling layer and the second filling layer.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses an adopt the different material of multilayer performance, to its integrated complex, develop a relatively independent composite floor slab who has the thermal-insulated function of sound insulation, its sound insulation performance index can reach national house one-level standard sound insulation effect and is showing especially, can be used to require higher building to impact sound insulation.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a concrete layer is cast in place; 2. a moisture barrier; 3. a first gypsum board layer; 4. a first filling layer; 5. a first profiled steel sheet; 6. prefabricating a concrete layer; 7. a stress dispersion layer; 8. a second gypsum board layer; 9. a second filling layer; 10. a second profiled steel sheet; 11. a third gypsum board layer.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1: as shown in fig. 1, the sound-insulating and heat-insulating composite floor slab described in this embodiment includes a cast-in-place concrete layer 1, a moisture-proof layer 2, a first gypsum board layer 3, a first filling layer 4, a first profiled steel sheet 5, a precast concrete layer 6, a stress dispersion layer 7, and a second gypsum board layer 8, wherein the cast-in-place concrete layer 1, the moisture-proof layer 2, the first gypsum board layer 3, the first profiled steel sheet 5, the precast concrete layer 6, the stress dispersion layer 7, and the second gypsum board layer 8 are sequentially laminated together from top to bottom, and the first filling layer 4 is filled in a gap of the first profiled steel sheet 5.

Specifically, first filling layer 4 and second filling layer 9 are rock wool boards. The rock wool board has better sound insulation and heat insulation effects.

Further, for better sound absorption effect, rock wool board that two kinds of different density stack from top to bottom is filled with in first filling layer 4 and the second filling layer 9.

Example 2: the sound-insulation and heat-insulation composite floor slab further comprises a second filling layer 9, a second profiled steel plate 10 and a third gypsum board layer 11, wherein the second profiled steel plate 10 and the third gypsum board layer 11 are sequentially stacked below the second gypsum board layer 8, and the second filling layer 9 is filled in a gap of the second profiled steel plate 10. In the embodiment, the second filling layer 9, the second profiled steel sheet 10 and the third gypsum board layer 11 are added on the basis of the embodiment 1, so that the air sound insulation and impact sound insulation effects are better.
