Abstract
The utility model relates to a compound sound absorption ceiling plate comprising a strip-shaped convex-concave inter-phase rectangle base plate, an adhesive layer and a glass fiber reinforcing plaster layer, wherein the adhesive layer is positioned on the strip-shaped convex-concave inter-phase rectangle base plate; the glass fiber reinforcing plaster layer is covered on the adhesive layer by a spraying method; the strip-shaped convex-concave inter-phase rectangle base plate is provided with a plurality of through holes in a strip-shaped groove, one side edge of the strip-shaped convex-concave inter-phase rectangle base plate is provided with an upper wedge opening, the other side edge of the strip-shaped convex-concave inter-phase rectangle base plate is provided with a lower wedge opening matched with the upper wedge opening, and a hanging piece is pre-embedded into the back surface of the strip-shaped convex-concave inter-phase rectangle base plate. The outer layer of the compoundsound absorption ceiling plate adopts the spraying method to cover glass staple fibers and strong plaster powder mixing materials on the outer layers of a light closed cell pearlite or an extrusion molding type polystyrene plate; and in addition, the utility model not only has the advantages of the compact and attractive appearance without deformation and the seamless splicing of the glass fiber reinforcing plaster layer, but also has the advantages of the light weight, the sound insulation and the fire prevention of the light closed cell pearlite, and can change the sound absorption effects on different frequency bands by changing into a strip-shaped convex way, the width of the groove and the dimensions of the through holes inside the groove.
Description
Technical field
The utility model relates to a kind of dalle of constructional materials, relates in particular to a kind of composite sound-absorbing ceiling board.
Background technology
At present, raising along with rapid development of economy and people's living standard, people have proposed the requirement of acoustics to most building, not only showing has such requirement to buildings such as concert hall, grand theater, assembly halls, at speech room, classroom, singing-hall even the local-style dwelling houses of school, railway car etc. such requirement is arranged all also.In the prior art, for the requirement of satisfying acoustics normally in the framework of wooden or metal filled glass fiber cotton etc. make porous material, and then cover metal sheet or other sheet material that is provided with sound-absorption hole, thereby constitute sound absorbing layer.This structure complex procedures, cost increases, and damping material forms dust and contaminated environment easily in the work progress at the scene.Also there are some Related products to come out in recent years, but in its technical indicator: not high, unsatisfactory aspect weight, intensity, outward appearance, the sound-absorbing effect Comprehensive Assessment, as can not to satisfy people demand.
The utility model content
The purpose of this utility model provides a kind of simple in structure, composite sound-absorbing ceiling board of simplifying production technology, reducing production costs, can carry out seamless close splicing.
The utility model is by the following technical programs in to realize: a kind of composite sound-absorbing ceiling board, its special pearl part is that it comprises: be the alternate rectangular substrate of strip convex-concave, be positioned at glue layer above the substrate, cover glue layer upper glass fiber reinforcement gypsum layer with spraying method, the described alternate rectangular slab of strip convex-concave that is has some through holes in it is the groove of strip.
The described alternate rectangular slab of strip convex-concave one side that is has the hyposphene mouth that matches is with it arranged on last wedge mouth, the opposed side edges.
The back side of the rectangular slab that described convex-concave is alternate is embedded with suspender member.
Described rectangular substrate is made by closed perlite.
Described rectangular substrate is by the poly-stupid vinyl plate of extrusion moulding type.
Good effect of the present utility model is: the composite sound-absorbing ceiling board that the utility model proposes, its outer spraying process that adopts, the short silk of glass fiber and high strength gypsum powder compound covered be coated on light closed hole perlite or the poly-stupid vinyl plate skin of extrusion moulding type, the outward appearance that had both had the glass fiber reinforced gypsum layer is fine and closely woven magnificent, indeformable, intensity is high, advantage that can be seamless spliced is again with closed perlite light weight, sound insulation, fireproof advantage.Be the size of the width and the groove inner via hole of strip projected parts form, groove by change, can change sound-absorbing effect, thereby reach desirable acoustics different frequency bands.According to the composite sound-absorbing ceiling board that the utility model is made, it is little to have a distortion, and it is little to do wet shrinkage factor, the intensity height, and the product breaking load is big, in light weight, can alleviate main building weight and member load, is a kind of for the high-quality NEW TYPE OF COMPOSITE sound-absorption ceiling board made of promoting.
Description of drawings
Fig. 1 is an example structure schematic diagram of the present utility model.
Fig. 2 is Fig. 1 embodiment A-A generalized section.
Schematic diagram when Fig. 3 hangs for Fig. 1 embodiment.
The specific embodiment
The utility model will be further described below in conjunction with embodiment: Fig. 1～Fig. 2 is the utility model mould preparation mould schematic diagram.A kind of composite sound-absorbing ceiling board, it comprises: be the alternate rectangular substrate of strip convex-concave 1, be positioned at glue layer 2 above the substrate, cover glue layer upper glass fiber reinforcement gypsum layer 3 with spraying method, the described alternate rectangular slab of strip convex-concave that is has some through holes 11 in it is the groove of strip.Fig. 2 A-A section is the sectional drawing that some lead to the hole site are arranged.Be the size of the width and the groove inner via hole of strip projected parts form, groove by change, can change sound-absorbing effect, thereby reach desirable acoustics different frequency bands.
Schematic diagram when Fig. 3 hangs for Fig. 1 embodiment.Being the alternate rectangular slab of strip convex-concave one side described in the figure has the hyposphene mouth 5 that matches is with it arranged on last wedge mouth 4, the opposed side edges.Seamless spliced by between existing member of last wedge mouth and hyposphene cause for gossip and the member.The back side at the alternate rectangular slab of described convex-concave is embedded with suspender member 6.Described suspender member is a L type hanger, can buy from market, provides convenience for hanging and splicing.The profile position of the present utility model that Fig. 3 provides is the profile position of no through hole.
Above-mentioned example does not constitute restriction of the present utility model, and all employings are equal to the technical scheme that form obtained of replacement or equivalent transformation, all drop within the protection domain of the present utility model.
