Abstract
The utility model provides a low-noise overhead type machine room which is arranged in a major structure to place a fan. The low-noise overhead type machine room comprises a side wall of the machine room, a cover plate of the machine room and a base plate of the machine room, wherein the cover plate of the machine room is arranged on the side wall of the machine room, the base plate of the machine room is connected with the side wall of the machine room, and the base plate of the machine room is further connected with a vertical component of the major structure. The existing machine room is internally and additionally provided with the base plate of the machine room, the base plate of the machine room is connected with the vertical component of the major structure, and the machine room and a floor slab are arranged with each other in an overhead way, i.e. the machine room and the floor slab are separated form each other, so that the vibration of the machine room can not be downwards transferred through the floor slab. Furthermore, the rigidity of the vertical component is less than that of a transverse structure, therefore, the amplitude can be greatly reduced, the resonance influence caused by the startup of the fan can be well avoided, and the noise can be preferably reduce since the vibration of the machine room is transferred by the vertical component. Furthermore, a part of vibration of the machine room can be absorbed by additionally arranging a shock absorbing structure between the base plate and the vertical component.
Description
Technical field
The utility model relates to a kind of technical field of building construction, relates in particular to a kind of low noise overhead type machine room.
Background technology
At present, the noise problem of building more and more receives people's attention and attention.Find through investigation; All floors that the noises that vibratory equipment produced such as source pump, water pump, new blower fan group, elevator can influence the place building are (along with the far and near difference in range noise source; Receive influence of noise degree difference), be the main noise source that room noise exceeds standard.
Wherein, new Ventilator Room noise is formed by stacking aerodynamic noise, mechanical noise, fresh wind tube road vibration noise etc., and its noise has bandwidth, low-frequency component is strong, propagation distance is far away, characteristic slowly decays.This noise like source characteristic mainly contains the following aspects: 1) dynamic property noise: because motor in the running, ventilation and heat has been broken the balance of original air pressure, makes friction generates noise between the air; 2) mechanical noise: piston, plunger move back and forth capable vibration, the generation pulse feature mechanical noise of rising of the bump that takes place when moving owing to motor; 3) fresh wind tube road vibration noise: when generally all being the steel plate machine run that approaches, because the noise that the continuous pipe vibration of windage vibration in the pipeline and unit produces owing to the fresh wind tube road.Its level of noise peak value mainly concentrates on the scope of frequency 31.5-250Hz.Above-mentioned each item noise is in service in new blower fan group with vibration, through different approaches, propagates towards periphery simultaneously, causes environment pollution, causes the adjacent premises ambient noise of new Ventilator Room to exceed standard.New blower fan group is propagated to body of wall and floor through pedestal in the vibration that running produces, and propagates around being reached downwards by metope and floor again, and the structure secondary radiation noise that this partial vibration excites is to the primary pollution source in room downstairs.New blower fan group noise passes through pipe transmmision; The noise that new blower fan group produces with in, low frequency is main; And the pressure fluctuation of an air-flow arranged at pipeline; Cause tube wall vibration radiation low-frequency noise, the room that this two parts noise pair room adjacent with pipeline and pipeline get into the end outlet place in the room forms influence of noise.
Now; For vibratory equipments such as the new blower fan group in roof, earth source heat pump units; Be to handle in engineering in the past through the method that the base at vibratory equipment adds damper; But the reason such as lack of standardization owing to the uncertain and construction and installation of the professional restriction that receives equipment producer, damping fittings quality can make that still the control of vibration noise is not very desirable, even the situation that noise exceeds standard occur.
Therefore, how providing a kind of can effective low noise overhead type machine room be the technical problem that those skilled in the art need to be resolved hurrily.

In order to reach above-mentioned purpose, the utility model adopts following technical scheme:
A kind of low noise overhead type machine room; Be arranged at and be used to place blower fan in the agent structure; Comprise machine room sidewall and machine room cover plate, said machine room cover plate is arranged on the machine room sidewall, also comprises machinery room bottom plate; Said machinery room bottom plate is connected with said machine room sidewall, and said machinery room bottom plate also is connected with the vertical member of agent structure.
In above-mentioned low noise overhead type machine room, the vertical member of said agent structure is shear wall or post.
In above-mentioned low noise overhead type machine room, said machinery room bottom plate is connected with vertical structure through shock-damping structure.
In above-mentioned low noise overhead type machine room, said blower fan is on damper setting and said machinery room bottom plate.
In above-mentioned low noise overhead type machine room, said machine room cover plate comprises ALC plate and steel work plate, and said steel work plate is arranged at said ALC plate top.
In above-mentioned low noise overhead type machine room, also be provided with waterproofing course between said ALC plate and the steel work plate.
In above-mentioned low noise overhead type machine room, said machine room sidewall is the ALC solid wall.
The beneficial effect of the utility model is following:
The low noise overhead type machine room of the utility model; Through will in existing machine room, setting up machinery room bottom plate and making machinery room bottom plate be connected with the vertical member of agent structure; Make that built on stilts setting is promptly separated each other between machine room and the floor, transmit downwards through floor thereby cut off the machine room vibration.And, because vertical member is littler than the rigidity of transversary, therefore,, can not only greatly reduce amplitude, and can be good at avoiding the resonance influence that fan starting possibly cause through crossing the vibration that vertical member transmits machine room, reduce noise thereby more utilize.In addition, through between base plate and vertical member, setting up shock-damping structure, can be so that the vibration of the part of machine room sponges through this shock-damping structure.
Description of drawings
The low noise overhead type machine room of the utility model is provided by following embodiment and accompanying drawing.
Fig. 1 is the structural representation of the low noise overhead type machine room of the utility model.
