Abstract
The utility model provides a noise reducing and isolating cover for construction. The noise reducing and isolating cover for construction comprises a pedestal bracket, a front baffle and two side baffles, wherein the front baffle and the two side baffles are fixedly connected with the pedestal bracket respectively; the two sides of the front baffle are fixedly connected with the two side baffles respectively; and the included angle of the two side baffles and the pedestal bracket is smaller than 90 degrees. The noise reducing and isolating cover for construction is simple and reasonable in structure and adopts a mode of isolating three surfaces and opening one surface, so that a worker can operate a road surface cutting machine in the noise reducing and isolating cover conveniently, and the construction of a crushing cannon is facilitated. During the construction, a noise source can be isolated, so that noise can be reflected and attenuated in the noise isolating cover repeatedly and a sound-isolating and noise-reducing effect is achieved.
Description
Technical field
The utility model relates to a kind of denoising device of communication pipe construction, relates in particular to a kind of construction noise reduction cage.
Background technology
In the communication pipe work progress, inevitably need to be cut or fragmentation pavement of road.The main pavement cutting machine that uses of road surface cutting, the noise of cast-cutting saw and pavement friction generation when pavement cutting machine noise source at work mainly comes from the noise of motor and road surface cutting.Through measuring, the noise of cutting machine motor is about the 60-80 decibel, and the noise during cutting of road surface is about 99 decibels.
The capital equipment of pavement breaking is broken big gun.The sound that the noise source of broken big gun when work sends in the afterburning constructional device of big gun hammer itself and big gun hammer tup clash into the noise of generation with the road structure layer, the noise of generation respectively more than 100 decibels with the 60-90 decibel.
According to " construction site ambient noise discharge standard " regulation (GB12523-2011), its emission limit, between daytime 70 decibels, 55 decibels of nights.And " the night noise maximum sound level must not be higher than 15dB over the amplitude of limit value.Be that the maximum discharge value of night construction noise is about 70dB.
At present, general communication pipe construction is mainly open work, can not reach national noise emission standard.
Summary of the invention
The purpose of this utility model is to provide a kind of construction noise reduction cage.
The purpose of this utility model is achieved through the following technical solutions:
The utility model provides a kind of construction noise reduction cage, comprise base support, front apron, two side shields, described front apron, two side shields are fixedly connected with described base support respectively, described front apron both sides are fixedly connected with described two side shields respectively, and the angle of described two side shields and base support is less than 90 °.
Described base support is wooden structures or steel work, and base support can be rectangle and also can be U-shaped.
Described front apron and two the optional wooden boards of side shield, glass fiber reinforced plastic or other sound insulations, attract sheet material.
Wherein, more preferably, described front apron and described two side shields top are fixed with respectively sound insulating panel parallel to the ground.
Wherein, more preferably, one side the fixing sound insulating panel vertical with side shield respectively of described two side shields.
Wherein, more preferably, described side shield and described front apron inboard are provided with acoustical cotton.
Wherein, more preferably, described base support bottom fixed installation steamboat.
The technical scheme provided by above-mentioned the utility model can find out, the utility model is simple and reasonable, adopts the modes of three isolation one side open, both has been convenient to the workman and operated therein pavement cutting machine, can be convenient to again the construction of broken big gun.Noise source can be isolated in construction, be made noise multiple attenuation in the noise isolation cover, to reach the effect of sound insulation and noise reducing.
The accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described in detail.
The utility model provides a kind of construction noise reduction cage, comprise base support 1, front apron 2 and side shield 3, front apron 2 vertically is fixed in one side of base support 1, side shield 3 is fixed in two other limit that base support is adjacent with being connected front apron 2, the angle of side shield 3 and base support 1 is located between 70 ° to 80 °, make side shield 3 form leaning angle in the noise reduction cage, front apron 2 and two side shields 3 are away from fixing respectively sound insulating panel parallel to the ground 4 on the one side on ground, two side shields 3 one side parallel with front apron 2 is fixing sound insulating panel 4 respectively also, the fixing thick acoustical cotton of 5cm on front apron 2 and the inboard wooden partition of side shield 3, base support is the rectangle wooden structures, base support 1 bottom is equipped with 4 steamboats 5.
Construction noise reduction cage totally is the terrace with edge shape, is provided with certain inclined angle, can make noise downwards and, to internal reflection, noise weakened after Multi reflection in cage, reaches the purpose of absorption maximum noise.
When carrying out the road surface cutting construction, with construction noise reduction cage, whole cutting machine and staff are covered, because construction noise reduction cage is provided with steamboat, so can there be the staff to move easily.
Because the utility model construction adopts three modes of isolating one side open, when broken big gun work, broken big gun big gun hammer is placed in broken road surface in construction noise reduction cage, and broken big gun cage is placed in to broken big gun work plane outside, cage is moved on broken limit, limit, both be convenient to the construction of broken big gun, again effective noise reduction.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
