The utility model is realized with following technical scheme: a kind of energy-saving sound insulation structure of Separate Home floor, it comprises reinforced concrete floor, be laid on the beam on the reinforced concrete floor, be laid on the waterproofing membrane on the beam, being cast in the thermal insulation concrete layer on the waterproofing membrane, is the floor architectural surface above the thermal insulation concrete layer.
Described reinforced concrete floor is situ Concrete Slabs, and thickness of slab is not less than 120mm, and the weighted standardization impact sound of nude concrete floor is arbitrarily downgraded≤80dB.
The floor crashing improvement amount of described beam is not less than 12dB, thickness 6-40mm; Beam is pressed in the skirt along turning over to more than the floor architectural surface on the body of wall periphery.
Waterproofing membrane adopts the PE film.
Described thermal insulation concrete layer thickness is 40-60mm.
Described thermal insulation concrete layer, when floor area greater than 30m
2The time, the top in the thermal insulation concrete layer is provided with the reinforced mesh that prevents concrete shrinkage and cracking.
Described floor face decorative layer is according to using function to determine.
The beneficial effects of the utility model are: have the functional requirement of heat preservation energy-saving and sound insulation vibration damping, and simple structure, easy construction is satisfied the requirement of high request Separate Home floor sound insulation, i.e. weighted transmission loss and pink noise frequency spectrum correction (R
w+ C＞50dB), floor weighted standardization impact sound is arbitrarily downgraded
≤ 65 dB, heat preservation and energy conservation effects is good.
Description of drawings
Fig. 1 is the energy-saving sound insulation organigram of Separate Home floor.
Among the figure: 1, reinforced concrete floor; 2, beam; 3, waterproofing membrane; 4, steel fabric sheet; 5, thermal insulation concrete layer; 6, floor architectural surface; 7, skirt.
The specific embodiment:
Below in conjunction with drawings and Examples the energy-saving sound insulation structure of Separate Home floor is done and to be specified.
Embodiment 1:
It comprises reinforced concrete floor 1 the energy-saving sound insulation structure of Separate Home floor, be laid on the beam 2 on the reinforced concrete floor, being laid on the waterproofing membrane 3 on the beam, being cast in the thermal insulation concrete layer 5 on the waterproofing membrane, is floor architectural surface 6 above the thermal insulation concrete layer.
Reinforced concrete floor 1 is the structural bearing layer, and the weighted standardization impact sound of nude concrete floor is arbitrarily downgraded≤80dB, and slab surfaces should be smooth, and presentation quality meets the requirements.It is the situ Concrete Slabs of 140mm that present embodiment adopts thickness.Plate is closely knit smooth, and presentation quality and planeness are qualified, and it is 79 dB that the weighted standardization impact sound of nude concrete floor is arbitrarily downgraded.
