Technical Field
The utility model belongs to the technical field of the building floor technique and specifically relates to a hollow floor sound-proof structure.
Background
In the construction of residences in the 60 to 90 th 20 th century, hollow core slabs (or referred to as hollow floors) have been used in large quantities as the main floor material. Because the sound insulation effect of the hollow floor slab is poor, and a large number of slab joints left in construction increase the sound transmission channels, residents of many old residential buildings can often listen to sounds of various upstairs, such as play, cry and scream, television sound, furniture movement sound, playing card entertainment sound and the like of upstairs and downstairs, and the residents are often interfered by the noises.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hollow floor sound-proof structure to the noise interference problem that the hollow floor sound-proof effect of solving old residential building leads to well.
In order to achieve the above object, the utility model provides a hollow floor sound-proof structure, it includes hollow floor and by supreme laying in proper order down the shock pad, the sound insulation pad, reinforcing bar net piece concrete layer, dampproof course and the floor layer of hollow floor top.
The hollow floor slab sound insulation structure as described above, wherein the shock-absorbing pad is a rubber shock-absorbing pad.
The hollow floor slab soundproofing structure as described above, wherein the soundproofing mat is a deadening felt.
The hollow floor slab sound insulation structure as described above, wherein the sound insulation pad is bonded to the shock-absorbing pad.
The hollow floor slab sound insulation structure comprises a concrete layer and a steel mesh embedded in the concrete layer.
The hollow floor sound insulation structure as described above, wherein the moisture-proof layer is a foamed moisture-proof mat.
Hollow floor sound-insulating structure as above, wherein, the thickness of shock pad is 5mm, the thickness of sound-insulating pad is 2mm, the thickness on reinforcing bar net piece concrete layer is 40mm, the thickness of dampproof course is 1 mm.
The utility model discloses a hollow floor sound-proof structure's characteristics and advantage are:
1. the hollow floor sound insulation structure of the utility model can effectively improve the sound insulation effect of the hollow floor of the old residential building by laying the shock pad, the sound insulation pad, the reinforced mesh concrete layer, the dampproof course and the floor layer above the hollow floor in sequence, and can block the propagation channel of sound because the hollow floor sound insulation structure completely covers the slab joint between the hollow floors, therefore, the hollow floor sound insulation structure of the utility model has good sound insulation effect and can effectively avoid the propagation of noise between the upper and lower buildings;
2. the hollow floor slab sound insulation structure of the utility model has the effects of shock absorption, moisture resistance and dust prevention by arranging the shock absorption pad and the moisture-proof layer;
3. the hollow floor slab sound insulation structure of the utility model has high structural strength and flat structure by arranging the reinforced mesh concrete layer;
4. the utility model discloses a hollow floor sound-proof structure, simple structure, construction convenient operation, it is with low costs.

Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1, the utility model provides a hollow floor sound-proof structure, it includes hollow floor 1 and by supreme shock pad 2 of laying in proper order in hollow floor 1 top down, give sound insulation and fill up 3, reinforcing bar net piece concrete layer 4, dampproof course 5 and floor layer 6, wherein, hollow floor 1 is the concrete precast slab, floor layer 6 that is located the top layer is the floor of ground ceramic tile or other types, dampproof course 5 that is located floor layer 6 lower one deck can play dustproof, preliminary shock attenuation and dampproofing effect, reinforcing bar net piece concrete layer 4 is used for the leveling, and high in structural strength, give sound insulation and fill up 3 and play syllable-dividing effect, shock pad 2 can play the shock attenuation effect.
The utility model discloses a hollow floor sound-proof structure can effectively improve hollow floor 1's syllable-dividing effect through lay shock pad 2, sound insulation pad 3, reinforcing bar net piece concrete layer 4, dampproof course 5 and floor layer 6 in proper order above hollow floor 1, because hollow floor sound-proof structure covers the slab joint between hollow floor 1 completely, can block the propagation channel of sound, consequently the utility model discloses a hollow floor sound-proof structure's sound insulation is effectual, can effectively avoid the propagation of upstairs and downstairs noise, simultaneously, the utility model discloses a hollow floor sound-proof structure still has shock attenuation, dampproofing, dustproof effect.
Further, the shock pad 2 is a rubber shock pad, and is simple in structure and convenient to construct and operate.
Further, the sound insulation pad 3 is a sound insulation felt, and is simple in structure and convenient to construct and operate.
Furthermore, the sound insulation pad 3 is bonded with the shock pad 2, so that the construction operation is very convenient.
As shown in fig. 1, further, the reinforced mesh concrete layer 4 includes a concrete layer 41 and a reinforced mesh 42 embedded in the concrete layer 41, the reinforced mesh 42 can increase the anti-cracking and anti-hollowing capacity of the concrete layer 41, the concrete layer 41 is used for leveling, and the moisture-proof layer 5 and the floor layer 6 are conveniently arranged above the concrete layer 41.
