Description
Technical Field
The utility model relates to a sound-proof board, it is used for boats and ships work accommodation etc. that have strict noise control demand region to inhale sound-proof board with height specifically to say so.
Background
The working and living cabin of the ship is influenced by the operation of numerous facilities such as ship electrical equipment, pipelines, ventilation and the like, the environmental noise of the cabin is higher, and the working efficiency and the rest of personnel are easily influenced. In order to reduce the environmental noise of the working and living cabins of the ships, sound insulation boards are installed in the working and living cabins of the ships.
At present, the sound insulation boards of ships are two types, which are composite rock wool boards and composite boards made of materials such as glass wool or ceramic wool (aluminum foil cloth/white cloth coated outside). However, the composite rock wool board is not flexible and convenient to install in a working area, is easily affected by pipelines, cables and other facilities with complicated installation positions, is large in field cutting workload and not beneficial to installation in place, reduces installation surfaces in cutting, greatly affects sound absorption and insulation effects, causes leakage and flying of rock wool serving as an internal core material due to field cutting, affects cabin air quality, and causes unnecessary leakage and flying of the core material due to field bolt installation penetration damage. Although the composite board made of glass wool or ceramic wool (wrapped aluminum foil/white cloth) is flexible to install on site, the volume weight is larger when the sound absorption coefficient is higher, and the wrapped aluminum foil or white cloth needs to be fixed by a large number of nails, so that the whole decorative surface is uneven, is not impact-resistant, and is easy to scratch and damage and has beautiful appearance.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a acoustic celotex board is inhaled with height to boats and ships, adopt this acoustic celotex board to need not the on-the-spot cutting, inhale the sound insulation effect better, can not influence cabin air quality, whole veneer is more level and smooth, and is crashproof, and is pleasing to the eye better.
In order to solve the problems, the following technical scheme is provided:
the utility model discloses a baffle is inhaled with height to boats and ships includes plate-like body. The plate-shaped body is hollow, and silencing holes are uniformly distributed on two side walls of the plate-shaped body. The bottom and the top of the inner cavity of the plate-shaped body are both provided with a U-shaped reinforcing plate, the closed part of each U-shaped reinforcing plate faces to the other U-shaped reinforcing plate, and two vertical edges of each U-shaped reinforcing plate are respectively abutted to the inner surfaces of two side walls of the plate-shaped body. And the tail part of the mounting and fixing screw sequentially penetrates through one side of the plate-shaped body, two vertical edges corresponding to the U-shaped reinforcing plate and the other side of the plate-shaped body. The inner cavity of the plate-shaped body between the two U-shaped reinforcing plates is filled with a high sound-absorbing core.
The panel body comprises a panel and a back plate which are arranged in parallel side by side, and the panel and the back plate respectively form two side walls of the panel body. The panel all around be connected with the bounding wall that arranges towards the backplate integratively, keep away from the panel on one side have the kink that is 90 bendings inwards, the pressure of backplate is between the kink, the U-shaped reinforcing plate is located kink and panel, the afterbody of installation set screw passes through panel, two perpendicular limits, kink and the backplate that correspond the U-shaped reinforcing plate in proper order.
The panel internal surface coats and is stamped the sound absorption membrane, and the upper portion and the lower part of sound absorption membrane are located respectively and correspond between the perpendicular limit of U-shaped reinforcing plate and panel, the afterbody of installation set screw runs through panel, sound absorption membrane, two perpendicular limits, kink and the backplate that correspond the U-shaped reinforcing plate in proper order.
By adopting the scheme, the method has the following advantages:
because the utility model discloses a boats and ships are with high plate body who inhales acoustic celotex board is cavity form, and the equipartition has the bloop on two lateral walls of plate body, and the bottom and the top of plate body inner chamber all have the U-shaped reinforcing plate, and plate body's upper portion and lower part all have installation set screw, and one side of plate body, two perpendicular limits that correspond the U-shaped reinforcing plate, plate body's opposite side are run through in proper order to installation set screw's afterbody, and it has the high sound core of inhaling to fill in the plate body inner chamber between two U-shaped reinforcing plates. This kind of acoustic celotex board is inhaled to height when the installation, directly links to each other with the boats and ships cabin through installation set screw, and the scene installation is nimble, convenient, need not the cutting, can not reduce the installation face, inhales the sound insulation effect better, avoids revealing and flying upward of the inside core that the cutting caused for cabin air quality is higher, installs set screw simultaneously and inhale the sound core with height and do not have the contact, has guaranteed the integrality of sound core is inhaled to height, has further avoided the core to leak the problem that flies upward. And the plate-shaped structure is adopted for supporting, so that the surface is smooth, the impact resistance is realized, the scratch damage is not easy, and the aesthetic degree is higher.
