Abstract
The utility model discloses a sound absorbing decorative board which belongs to architectural decoration. The surface of a main body board is regularly provided with a plurality of big circular holes and small circular holes at intervals or the holes on a back surface are in a step shape. An upper surface is coated with a fire resisting layer and a bottom surface is adhered to a non-woven fabric layer. The product of the utility model has an excellent sound absorbing effect and the sound-absorbing coefficient is as high as 0.8 to 0.9. The utility model also has a fire resisting function, only splicing requirements in decorative construction, rapid construction speed, strong decorative integral performance, beauty and grace and can be manufactured according to user's requirements. The utility model is the new architectural decorative board with more functions than the sound absorbing decorative board at present and is popular among users.
Description
Technical field
The utility model belongs to the building and ornament materials scope, particularly has a kind of sound absorption decorative plate of good decorative effect and high acoustic absorption performance.
Background technology
Modern cinema, multi-functional assembly hall, comprehensive stadiums, recording room, concert hall etc. not only have specific (special) requirements to acoustically effective, and decorative effect is also had very high requirement, and existing mineral wool sound absorption board, perforated metal panel etc. all have sound absorption.But acoustically effective can not be satisfactory, also is not easy to satisfy user's requirement on decorative effect.
Summary of the invention
The purpose of this utility model provides a kind of sound absorption decorative plate, it is characterized in that: rule, at interval arrangement big hole 3 and small sircle hole 4 on main board 1 plane, the also compound one deck fire prevention of its upper surface, crashproof coating 2, sound insulation, the damp proof insulation layer 5 that layer of non-woven fabric is formed posted in the bottom surface.
Described small sircle hole 4 is in the central authorities of four big holes 3, or small sircle hole 4 back sides are big hole 3.
Described big hole 3 or small sircle hole 4 can also be stepped hole 6 at main board 1 back portion.
Slotting between 7, two grooves in addition in the surface of described sound absorption decorative plate is ornamental strip 8, has slotted hole 3 in fluting 7 at interval, and the distribution of its slotted hole 3 is that back one hole of arranging is between last row's two holes.
Described fluting sound absorption decorative plate also can be aimed at hole 3, and ornamental strip 8 orthogonal intersections stick together with the mutual back side.
Described slotted hole can also be step at the main board back portion; The shape of its slotted hole also can be rhombus, square, or 8 fonts.
The beneficial effect that the utility model reaches is 1. to have changed the simple function of some sound absorption materials in the prior art, has both had good acoustically effective, and sound absorption coefficient is about 0.8-0.9, has multiple functions such as decoration, fire prevention, crashproof, sound insulation, damp proof insulation again.2. assembly unit convenience when installing, surperficial globality is strong, and speed of application is fast.
Description of drawings
Fig. 1 is the sound absorption decorative plate structural representation;
Fig. 2 is big hole or the small sircle hole back side form structure schematic diagram of Fig. 1;
Fig. 3 is the sound absorption decorative plate structural representation of surperficial tape, groove.
The specific embodiment
Figure 1 shows that the sound absorption decorative plate structural representation.Its main board 1 is made for high density wood based panel or other material.Post layer of non-woven fabric puigging 5 in its bottom surface, be compounded with fire prevention, crashproof coating 2 at upper surface, on the main body plane rule, be spaced big hole 3 and small sircle hole 4, and one row big hole 3, one row's small sircle hole 4 is a small sircle hole 4 in the central authorities of four big holes 3.Or small sircle hole 4 back sides are big hole 3.The shape in hole, main board 1 back side can be step (as shown in Figure 2).Also having a kind of structure is to have narrow groove 7 (as shown in Figure 3) at upper surface, have slotted hole 3 at interval in groove, and adjacent two platoon leader's circular holes 3 is in staggered distribution.The incrustation bar of two-ply intersects vertical, and hole 3 is aimed at, and to sticking together, aforementioned slotted hole 3 can also be rhombus, square or 8 fonts with the mutual back side; The back side can also be step.When sound wave passed on the decoration wooden partition, large and small circular hole 3,4 absorbed sound, and reflective sound wave makes it cancel out each other, weaken, and reduced echo interference in the hall greatly, and existing acoustically effective has decoration function again.The face coat energy is fire-retardant, fireproof performance is good.Need only assembly unit during construction, speed of application is fast, and the decoration globality is strong, generous, attractive in appearance.
