Plate in Felt Inner Constitution resonance sound-absorbing chamber.
Further, described cement extrusion board is formed in one plate, and the cross section of cement extrusion board is generally " U "-shaped,
Including one piece of rectangular base plate and the side plate with box section positioned at the long side both sides of base plate, it is respectively arranged with the inside of biside plate
The draw-in groove that one length direction along side plate is arranged, described microgranule acoustic board are stuck in two described clamp bar slots and are squeezed with cement
Ejecting plate constitutes resonance sound-absorbing chamber.
Further, at least one ribs that arranges along the length direction of the base plate is provided with base plate, plus
Fit with the bottom surface of microgranule acoustic board at the top of strong rib.
Further, the cross section of the side plate is right-angled trapezium section, and is under right-angled trapezium near base plate side
Bottom, the right-angle side of right-angled trapezium are located at outside.
Further, the concavo-convex jointing end face along Felt bearing of trend, institute are provided with described cement extrusion board
The convex surface for stating concavo-convex jointing end face is raised solid plate face, and the concave surface of the concavo-convex jointing end face is fluting face.
Further, bond between described cement extrusion board and microgranule acoustic board.
The beneficial effects of the utility model are：Enclosure wall Felt of the present utility model, sound absorbing capabilities are stable, structure letter
Single, easy to make, production efficiency is high, is suitable for mass production.

Specific embodiment
With reference to the accompanying drawings and examples this utility model is further illustrated.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, enclosure wall Felt of the present utility model is by 2 groups of acoustic board and cement extrusion board
Conjunction is formed, and described acoustic board is microgranule acoustic board 1, and described microgranule acoustic board 1 is formed with adhesive bond by microparticle material,
Microparticle material is one or more the combination in haydite, sand grains, wood flour, plastic foam or cinder, the mesh of microparticle material
Number is 20-60 mesh, and binding agent is one or more in epoxy resin, phenolic resin, Lauxite or furfuryl alcohol resin
Combination, 3%-15% of the binder content for microparticle material quality.
Described cement extrusion board 2 is formed in one plate, and the cross section of cement extrusion board 2 is generally " U "-shaped, including one piece
Rectangular base plate 10 and the side plate 6 with box section positioned at 10 long side both sides of base plate, are respectively arranged with one on the inside of biside plate 6
The draw-in groove 4 that bar is arranged along the length direction of side plate 6, described microgranule acoustic board 1 are stuck in two described clamp bar slots 4 and cement
Extrusion board 2 constitutes resonance sound-absorbing chamber 7, and microgranule acoustic board 1 is shaped as cuboid, and its thickness matches with 4 size of draw-in groove, aobvious
So, the shape of microgranule acoustic board 1 can also be the other shapes beyond cuboid, such as microgranule acoustic board of the cross section in convex shape
1 etc., as long as meeting in the draw-in groove 4 that microgranule acoustic board 1 can be stuck on side plate 6 and there is resonance sound-absorbing with the composition of cement extrusion board 2
The Felt in chamber 7；The thickness in resonance sound-absorbing chamber 7 can be according to draw-in groove 4 on side plate 6 position be adjusted；By the last of the twelve Earthly Branches
Mu Huozi resonance sound-absorbings principle understands that the resonance sound-absorbing chamber 7 can increase the sound absorbing capabilities of enclosure wall Felt.In addition, for general
Microgranule acoustic board 1 is more clamped securely in draw-in groove 4, and bond between microgranule acoustic board 1 and draw-in groove 4 layer binder 3.
In order to strengthen cement extrusion board 2 bulk strength and can support particulates acoustic board 1, be provided with base plate 10 to
The bottom surface of the ribs 5 that a few length direction along the base plate 10 is arranged, the top of ribs 5 and microgranule acoustic board 1
Laminating.
For increase draw-in groove 4 intensity so that its in process of setting and be subject to microgranule acoustic board 1 compressing when will not
Deform, the side plate 6 is fabricated to the side plate 6 that cross section is right-angled trapezium section, near the base plate 10 of cement extrusion board 2
Side is gone to the bottom for right-angled trapezium, and the right-angle side of right-angled trapezium is located on the outside of side plate 6.
In order that two pieces of adjacent enclosure wall Felts easily can be coupled together, on cement extrusion board 2, it is provided with edge
The concavo-convex jointing end face of enclosure wall Felt bearing of trend, the convex surface 8 of concavo-convex jointing end face is raised solid plate face, described recessed
