Abstract
The utility model discloses a dedicated sound absorbing and sound insulating board for a machine room. The dedicated sound absorbing and sound insulating board comprises a hollow body, the hollow body is composed of a face board, a back board and a lateral board which are connected, damping sound absorbing cotton is arranged in the hollow body, the connecting portions between the face board, the back board and the lateral board are of convex-concave structures, the face board, the back board and the lateral board are mutually in embedded connection through the convex-concave structures, and the connecting portions are reinforced through rivets. The face body is a round hole type sound absorbing board, the perforation percentage of the face board is 8%-12%, and protruded teeth are arranged on the inner side of the back board. The dedicated sound absorbing and sound insulating board for the machine room has the advantages of being strong in stability, thin in the whole thickness and good in sound absorbing and sound insulating effect.
Description
Technical field
The utility model relates to a kind of metope and pastes sound absorption material, relates in particular to a kind of machine room inner wall panel simultaneously with sound-absorbing and sound insulation function.
Background technology
Most people has such impression, when mutually same machine is placed in workshop, want high more than being placed on noise outside workshop, this is because most of workshops inner surface is made up of some reinforced concrete prefabricated ceilings or floor, hard smooth metope and glass door and window etc.In such workshop, workman is transmitted machine sound except hearing by air dielectric, also can hear the reverberation sound being come by smooth and hard inner surface and machinery equipment surface multiple reflections, and the stack of these two kinds of noises, has strengthened noise intensity in workshop.Reduce the intensity of this noise as wanted, just need be at ceiling, surrounding metope or space mounting sound absorption material.
At present, for the problems referred to above, adopt metope attaching absorbent treatment and soundproof course to reduce the impact of overall noise on staff and surrounding environment in workshop more.This absorbent treatment and soundproof course are mainly made up of sound absorption material and sound absorption cavity, reach high sound absorption and insulation amount, absorbent treatment adds soundproof course thickness up to more than 50cm, cause workshop overall dimensions to diminish, and complicated construction technique, easily produce and leak voice phenomenon, water resistance is poor, cost is high, maintenance and difficult in maintenance.
Utility model content
For solving above-mentioned prior art problem, the purpose of this utility model is to provide a kind of machine room special sound-absorbing, resistant panels, to have at the same time under good sound absorption and insulation performance prerequisite, reduces its thickness, and has installation stable connection, the features such as good airproof performance.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The special sound-absorbing, resistant panels of a kind of machine room, comprise the ducted body being connected to form by panel, backboard and side plate, in described ducted body, be provided with damping acoustical cotton, it is characterized in that: described panel, backboard and the side plate place of interconnecting are concave-convex type structure, and mutually embed connection by concave-convex type structure, and junction is provided with rivet reinforcing, wherein, described panel is circular hole abatvoix, perforated percentage 8%-12%, and described backboard inner side is provided with lobe.
Preferably, described back plate thickness is 0.8mm-1.2mm.
Preferably, described damping acoustical cotton is coated with hydrophobic sound-absorbing nonwoven.
Preferably, described panel, backboard and the side plate place of interconnecting are provided with sealing joint strip.
Preferably, described ducted body edge connects with the dislocation between side plate through panel, backboard, and ducted body edge is configured to concave-convex type structure.
By technique scheme, the beneficial effects of the utility model are:
1, by adopting concavo-convex embedded connecting structure to be connected with side plate the panel of sound barrier, backboard, and reinforce by rivet, greatly strengthened the stability connecting;
2, adopt thinner backboard and the panel of 8%-12% perforated percentage, make it reduce integral thickness having on superperformance basis;
3, by the setting of lobe inside backboard, can prevent the displacement of inner hydrophobic sound-absorbing nonwoven and damping acoustical cotton, and the setting of each plate body junction sealing joint strip, water resistance and soundproof effect can be increased;
4, connect with the dislocation between side plate by panel, backboard, plate ducted body edge is configured to concave-convex type structure, facilitate interconnecting between each sound-absorbing, resistant panels.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but should be considered as restriction of the present utility model.
Referring to Fig. 1, the special sound-absorbing, resistant panels of a kind of machine room, the ducted body that the backboard 2 that to comprise by the panel 1 that offers perforation, thickness be 0.8mm-1.2mm and the side plate 3 of four sides connect to form; Ducted body edge connects with the dislocation between side plate through panel, backboard, and ducted body edge is configured to concave-convex type structure;
Wherein, the perforated percentage of panel 1 is 8%-12%, and backboard inner side is provided with lobe 7, is provided with damping acoustical cotton 4 in ducted body, and damping acoustical cotton 4 is coated with hydrophobic sound-absorbing nonwoven, and is fixed on ducted body inside by lobe 7; Side plate 3 places of interconnecting of panel 1, backboard 2 and four sides are concave-convex type structure, and each plate body embeds connection mutually by concave-convex type structure, and realize sealing by the sealing joint strip 5 that is arranged on concave-convex type structure place, and each junction is provided with rivet 6 and reinforces.
Disclosed is above only specific embodiment of the utility model; but the utility model is not limited thereto; for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model principle, the distortion of making should be considered as belonging to protection domain of the present utility model.
