Abstract
The utility model discloses a sound-insulating vibration-reducing structure for an indoor drain pipe and belongs to the technical field of sound insulation for houses. Vertical and horizontal sound-insulating vibration-reducing systems are arranged through the drain pipe of a floor slab. According to the vertical sound-insulating vibration-reducing system, the drain pipe penetrates an embedded casing, a cavity is reserved between the drain pipe and the casing, rock wool is embedded in the cavity, and micro-expansion waterproof mortar is used between the casing and the floor slab for sealing. According to the horizontal sound-insulating vibration-reducing system, a vibration-reducing pad is laid on a leveling base layer of the floor slab, then upward edge turning is performed vertically along the casing, self-leveling concrete is poured on the vibration-reducing pad, and an indoor decorative layer is installed finally. By means of the structure, drain noise and vibration of the drain pipe can be effectively reduced, the sound-insulating vibration-reducing structure is applicable to sound insulation and vibration reduction of indoor drain pipes of healthy houses and high-requirement houses, healthy indoor sound environments are constructed for users.

Summary of the invention
The utility model provides a kind of indoor drainage pipe sound insulation vibration damping structure, for lowering the noise and vibration problem of Indoor Residential Ecological drainage pipe, improves the acoustic environment of indoor drainage pipe noise and vibration.
The utility model is achieved through the following technical solutions: a kind of indoor drainage pipe sound insulation vibration damping structure, comprise waste pipe, described waste pipe is mute pipe, be outside equipped with waste pipe sound insulation vibration damping equipment at waste pipe, described sound insulation vibration damping equipment comprises that vertical sound insulation subtracts system and level to the sound insulation vibration insulating system; Described vertical vibration insulating system comprises and the service sleeve of waste pipe coaxial sleeve outside waste pipe, leave gap between service sleeve and waste pipe, be filled with the rock wool for sound insulation in gap, the two ends of rock wool seal with elastic sealing paste, between service sleeve and reinforced concrete floor, with the sealing of microdilatancy waterproof mortar, the lower end of microdilatancy waterproof mortar is useful on the cement supporting plate of holding the microdilatancy waterproof mortar; Described level sound insulation vibration insulating system comprises the damping pad around service sleeve be laid on the floor screed-coat, at the contact service sleeve, goes out to have along flanging curved on service sleeve, between damping pad and service sleeve and reinforced concrete floor, forms elastic buffer.
Further described waste pipe adopts noise level to be no more than the mute pipe of 45dB.
Described service sleeve adopts cast iron tube, and between service sleeve and waste pipe, gap is not less than 50mm.
Density>=60kg/m of filling rock wool in described service sleeve and waste pipe gap
3.
Also be provided with Self-leveling pea gravel concreten layer and decorative layer on damping pad.
Described damping pad exceeds floor decorative layer 50mm flexible fastening along the sleeve pipe crimp that makes progress.
The thickness of described cement supporting plate is 12-15mm.
The beneficial effects of the utility model are: said structure can effectively reduce draining noise and the vibration of waste pipe, is applicable to the sound insulation vibration damping way of healthy residence, high request Indoor Residential Ecological waste pipe, for the user builds the indoor noise environment of a health.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-waste pipe; 2-rock wool; 3-service sleeve; 4-microdilatancy waterproof mortar; 5-cement supporting plate; 6-elastic sealing paste; 7-reinforced concrete floor; 8-floor screed-coat; 9-damping pad; 10-Self-leveling pea gravel concreten; 11-decorative layer.
Embodiment
Below in conjunction with accompanying drawing 1 and embodiment, the utility model is described further.
As shown in Figure 1, a kind of indoor drainage pipe sound insulation vibration damping structure, comprise waste pipe 1, and waste pipe 1 is mute pipe, at waste pipe, is outside equipped with waste pipe sound insulation vibration damping equipment; The sound insulation vibration damping equipment comprises that vertical sound insulation subtracts system and level to the sound insulation vibration insulating system; Vertical vibration insulating system comprises and the service sleeve 3 of waste pipe 1 coaxial sleeve outside waste pipe, leave gap between service sleeve 3 and waste pipe 1, be filled with the rock wool 2 for sound insulation in gap, elastic sealing paste 6 sealings for the two ends of rock wool 2, between service sleeve 3 and reinforced concrete floor, with 4 sealings of microdilatancy waterproof mortar, the lower end of microdilatancy waterproof mortar 4 is useful on the cement supporting plate 5 of holding microdilatancy waterproof mortar 4; Described level sound insulation vibration insulating system comprises the damping pad around service sleeve 39 be laid on floor screed-coat 8, go out to have along flanging curved on service sleeve at contact service sleeve 3, between damping pad 9 and service sleeve 3 and reinforced concrete floor 7, form elastic buffer.
