A combined sound barrier unit plate comprises a sound absorption plate, a sound insulation plate, an end plate, a clamp, sound absorption cotton, hydrophobic materials and rivets. The hydrophobic material wraps the sound absorption cotton and then is placed into the cavity of the sound absorption plate, and the clips are placed around the sound absorption cotton; the end plates are placed on the inner sides of two ends of the sound absorption plate to form a uncovered box body; and finally, placing the sound insulation plate in a reserved position of the box body, and fixing the sound absorption and insulation plate by using a rivet to form a complete unit plate.
The sound absorption plate is a metal sheet plated with aluminum, zinc or aluminum, sound absorption holes are uniformly distributed on the surface of the sound absorption plate, and the whole sound absorption plate is rectangular. Two long sides of the rectangle are oppositely bent and are pressed into a C shape at one time; one side (upper part) of the sound absorption plate is pressed with a convex edge and a rivet mounting hole by using a die, and the other side (lower part) of the sound absorption plate is pressed with a concave edge and a rivet mounting hole by using a die; and a plurality of shallow surface indentations are pressed at the positions with the sound absorption holes, so that the rigidity is enhanced. The sound absorption plate is a main structural framework, and sound waves are transmitted through the surface openings to absorb sound.
The sound insulation board is a metal thin plate made of aluminum-zinc or aluminum materials and the like, and a plurality of shallow indentations on the surface are pressed to enhance the rigidity. The whole body is also rectangular. Two long sides of the rectangle are oppositely bent and are pressed into a C shape at one time; the sound insulation board pressure groove is inserted into the sound absorption board to form a frame together with the sound absorption board.
The end plate is a metal thin plate plated with aluminum, zinc or aluminum, and the like, one side of the die is pressed into a rectangle with a C-shaped section, and the upper side and the lower side of the rectangle correspond to the concave-convex shape of the sound absorption plate. The end plate is inserted into the inner side of the end part of the sound absorption plate and forms a completed cavity with the sound absorption plate of the sound insulation plate, and meanwhile, the effect of enhancing the strength and rigidity of the unit plate is achieved.
The sound-absorbing cotton is cuboid rock wool, and hydrophobic materials such as hydrophobic cloth or non-woven fabric are wrapped on the outer side of the sound-absorbing cotton, so that the sound-absorbing cotton is a sound-absorbing main body.
The checkpost is that sheet metal suppression, and the equipartition plays the cotton effect of fixed sound absorption around the sound absorption.
The rivets are standard parts and are used for connecting all parts, so that the unit plates are fixedly connected.
The sound absorption plate and the sound insulation plate are connected through the rivets, the rivets are arranged at the upper part and the lower part, when a plurality of unit plates are installed, the rivets of the unit plates are pressed by the unit plates on the unit plates, and the unit plates cannot fall off even if the rivets are loosened, so that potential safety hazards caused by falling off of the rivets on the exposed surfaces of the unit plates are thoroughly eliminated.
The invention has the following beneficial effects:
1. combining the components: sorting of parts, assembling with different materials
2. Assembly line operation: the manufacturing process is optimized, and the efficiency is improved;
3. safe and reliable: eliminating the rivet from being exposed.
