Space outward opening being left to placement keel on described frame 3, when the corresponding mirror image on two pieces of described frames 3 is close to placement, the keel realizing connecting fast are placed in central hollow position, and contact position employing injecting glue mode is tightly connected.
Described damping material 4 is the outside glass silk flosssilk wadding or the rock wool that are surrounded by the longitudinal laying of glass fabric, and described longitudinal direction is the direction vertical with outer panels 2 with wainscot 1.
Described a kind of sound-absorbing muffler plate also comprises the damping of increase outside plate, reduces outside plate resonance, and has the glass magnesium plate (5) promoting defening effect.
Described glass magnesium plate 5 thickness is 5mm ~ 6mm, is connected with outer panels 2.
Described wainscot 1 and damping material 4, outer panels 2 and glass magnesium plate 5, frame 3 and damping material 4, adopt injecting glue mode to seal between damping material 4 and glass magnesium plate 5.Mode connect, junction metal end have spray paint anticorrosion.
The advantage of a kind of sound-absorbing muffler plate of the present invention is:
1) the present invention adopts bonding pressing process, is convenient to processing and manufacturing, good looking appearance, surfacing, abandons welding procedure, avoids the welding deformation problem of product.
2) the present invention is different from traditional transverse direction and lays cellucotton, and adopt the method for longitudinally laying to install cellucotton, this kind of method can increase wall intensity, planeness.
3) the present invention does not separately establish skeleton in metope wallboard inside, and the technique of and bonding compression cotton by longitudinal fiber, can ensure the flat appearance degree of metope wallboard, effectively reduce the weight of metope wallboard self, both save cost, conveniently transported installation, reduce again the cost of labor of processing.
4) the present invention is by the configuration design of frame and keel, realizes splicing assembling fast.Than conventional wall face the wall and meditate plate need be welded on prepackage skeleton on mounting means, effectively improve installation effectiveness.
