Description
Technical field
The utility model relates to a kind of sound arrester, particularly relates to a kind of acoustic barrier.
Background technology
Along with city is growing, vehicle noise pollutes also day by day serious, and modern medicine is verified, and noise is not only detrimental to health, and also has a strong impact on normal life and the work of people.Therefore control noise has become problem in the urgent need to address.The complex structure of existing acoustic barrier, cost is high, and soundproof effect is undesirable.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of acoustic barrier, and its structure is simple, and cost is low, improves soundproof effect.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of acoustic barrier, it is characterized in that, it comprises horizontal keel, along top keel, gypsum plank, rock cotton board, bracing frame, dividing plate, along ground joist, angle steel shelf, centre keel, sound insulating panel, sound insulating seal bar, damping keel, along top keel, sound insulating seal bar, along ground joist, damping keel are in turn connected to form a framework, gypsum plank, rock cotton board, bracing frame, dividing plate, angle steel shelf is all positioned at this framework, horizontal keel are vertical with sound insulating panel to be fixed, horizontal keel and sound insulating panel are all positioned at dividing plate, dividing plate is positioned at a side of gypsum plank, rock cotton board is positioned at another side of gypsum plank, sound insulating panel is between rock cotton board and sound insulating seal bar, bracing frame is between dividing plate and angle steel shelf, and angle steel shelf is positioned at the inner side of damping keel.
Preferably, described angle steel shelf is provided with rivet.
Preferably, the cross sectional shape of described framework is trapezoidal.
Positive progressive effect of the present utility model is: the structure of the utility model acoustic barrier is simple, and cost is low, improves soundproof effect.In addition, the utility model acoustic barrier adopts fabricated construction, increases work efficiency, and shortens the engineering time, and it also possesses that intensity is high, self light, easy-maintaining, durable, upgrade the advantages such as convenient.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model acoustic barrier.
Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model acoustic barrier comprise horizontal keel 1, along top keel 3, gypsum plank 4, rock cotton board 5, bracing frame 6, dividing plate 7, along ground joist 8, angle steel shelf 9, centre keel 10, sound insulating panel 11, sound insulating seal bar 12, damping keel 13, along top keel 3, sound insulating seal bar 12, be in turn connected to form a framework along ground joist 8, damping keel 13, gypsum plank 4, rock cotton board 5, bracing frame 6, dividing plate 7, angle steel shelf 9 are all positioned at this framework, horizontal keel 1 are vertical with sound insulating panel 11 to be fixed, and horizontal keel 1 are all positioned at dividing plate 7 with sound insulating panel 11; Dividing plate 7 is positioned at a side of gypsum plank 4; Rock cotton board 5 is positioned at another side of gypsum plank 4; Sound insulating panel 11 is between rock cotton board 5 and sound insulating seal bar 12; Bracing frame 6 is between dividing plate 7 and angle steel shelf 9, and angle steel shelf 9 is positioned at the inner side of damping keel 13.
The horizontal keel fixing inner supporting structure that form acoustic barrier vertical with centre keel.Dividing plate serves connection, improves the effect of intensity.Bracing frame serves the effect supporting whole device.Gypsum plank plays sound insulation, thermal insulation and fireproof effect.Rock cotton board has excellent fire prevention, insulation and sound absorption qualities.Along top keel, along ground joist etc. mainly in order to form framework.Damping keel can carry out damping to sound, thus improve soundproof effect.Angle steel shelf.Sound insulating panel carries out sound insulation.Sound insulating seal bar is filled up connection gap place, accomplishes not occur gaping of joints between plate, the overall soundproof effect of device is significantly promoted.
Angle steel shelf 9 is provided with rivet 2, and convenient like this and other element is fixed.
The cross sectional shape of framework is trapezoidal, saves material like this, reduces costs.
The structure of the utility model acoustic barrier is simple, and cost is low, and rock cotton board, damping keel, sound insulating seal bar, sound insulating panel, gypsum plank all have soundproof effect, improve soundproof effect like this.The utility model acoustic barrier adopts fabricated construction, increases work efficiency, and shortens the engineering time, and it also possesses that intensity is high, self light, easy-maintaining, durable, upgrade the advantages such as convenient.
Above-described specific embodiment; the technical problem of solution of the present utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
