The utility model discloses resistant the times layer that sets up, should resistantly wait layer can effective resistance light, moisture etc. Is to the destruction of ceiling, is favorable to improving the life of ceiling, the buckled plate that sets up with inhale the cotton layer of sound in can the absorption chamber, absorbing effect is good, makes the indoor lower sound that keeps, provides the environment for people's life and rest, cement congeals the layer can not burn and not have poisonous gas release under high temperature, belong to security environmental protection material to used raw and other materials are whole to come from the nature, does not have any corrosivity and radioactivity. The utility model discloses the quality is light, easy carries, cuts well, is under construction easily, to the high -rise building structure, can alleviate its load very much, reduces construction costs and longe -lived.
Description
Technical field
This utility model relates to a kind of ceiling, specifically sound-and-fire proof metal ceiling.
Background technology
Ceiling is the general name to decoration indoor roof material.How with straw mat, reed mat, plank etc. as main material in past traditional residence.Along with the progress more modern architecture material of science and technology is employed to come in.Plasterboard, mineral wool board, PVC, aluminum-pinch and soft variola etc. are had on market.But existing ceiling only has a kind of function, it is intended to temperature and the control of sound, but the environment factor that people receive in indoor is a lot, accordingly, it would be desirable to a kind of ceiling can carry out multi-direction control to indoor environment.
Utility model content
The purpose of this utility model be to provide a kind of light weight, easily carry, cut well, construct easy, service life length sound-and-fire proof metal ceiling, to solve the problem of proposition in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
Sound-and-fire proof metal ceiling, including decorative plies, weathering layer, corrugated plating, acoustical cotton layer, heat-insulation layer, cement cementitious layer and sheet-metal layers, and sets gradually.
Further: described decorative layer is grid cloth.
Further: the thickness of described weathering layer is 2～4mm, weathering layer is Modifying Character for PVC Plastic layer, acrylicstyrene-acrylonitrile layer or polymethyl methacrylate layers.
Further: described corrugated plating is set to bellows-shaped, thickness is 1～2mm.
Further: described heat-insulation layer is rock cotton board, the thickness of heat-insulation layer is 5～8mm.
Further: described sheet-metal layers is aluminum, thickness is 1～3mm.
Compared with prior art, the beneficial effects of the utility model are: the weathering layer that this utility model is arranged, and this weathering layer can be effective against the destruction to ceiling such as light, dampness, are conducive to improving the service life of ceiling；The corrugated plating arranged and acoustical cotton layer can sound in absorption chamber, sound-absorbing effect is good, make the sound that indoor holding is relatively low, life and offer environment of having a rest for people, the heat-insulation layer simultaneously arranged reduces roof and the extraneous speed carrying out heat exchange, maintains the temperature of indoor adaptation, and sheet-metal layers makes ceiling more solid, it is easy to safety, safety and stability；Cement cementitious layer at high temperature will burn and not have toxic gas to discharge, and belongs to safety environment-friendly materials, and raw materials is all from the Nature, without any corrosivity and radioactivity.This utility model light weight, easily carry, cut well, construct easily, for high building structure, its load can be alleviated especially, reduce building cost and the life-span is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of sound-and-fire proof metal ceiling.
In figure: 1-weathering layer, 2-corrugated plating, 3-acoustical cotton layer, 4-heat-insulation layer, the cement cementitious layer of 5-, 6-sheet-metal layers, 7-decorative layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to figure, in this utility model embodiment, sound-and-fire proof metal ceiling, including decorative plies 7, weathering layer 1, corrugated plating 2, acoustical cotton layer 3, heat-insulation layer 4, cement cementitious layer 5 and sheet-metal layers 6, and set gradually；
Described decorative layer 7 is grid cloth.
The thickness of weathering layer 1 is 2～4mm, and weathering layer 1 is Modifying Character for PVC Plastic layer, acrylicstyrene-acrylonitrile layer or is polymethyl methacrylate layers etc..
Corrugated plating 2 is set to bellows-shaped, and thickness is 1～2mm, and sound wave can reflect the carrying out of corrugated surface and reflect and carry out noise reduction.
The material of acoustical cotton layer 3 is acoustical cotton, and acoustical cotton layer 3 covers the back side at corrugated plating 2, by the sound absorption of acoustical cotton layer 3 so that ceiling can reach good sound-absorbing effect.
Heat-insulation layer 4 is rock cotton board, and rock cotton board is a kind of excellent insulation material, and the thickness of heat-insulation layer 4 is 5～8mm.
The component that cement cementitious layer 5 includes has: cement, eps foam granule, fiber cloth, bentonite, fine particle calcium carbonate, bath of glass, water, foaming agent and latex；Above-mentioned raw material at high temperature will burn and not have toxic gas to discharge, and belongs to safety environment-friendly materials, and raw materials is all from the Nature, without any corrosivity and radioactivity；Production technology is: measure cement, eps foam granule, fiber cloth, bentonite, fine particle calcium carbonate, bath of glass, water, foaming agent and latex according to certain mass percent, pour into afterwards in mixing plant, stir, again by the material transportation that is stirred to extrusion equipment, by extrusion equipment extrusion forming, make cement cementitious layer.
Sheet-metal layers 6 is aluminum, and thickness is 1～3mm, and sheet-metal layers 6 strengthens the intensity of ceiling so that it is can adapt to more roof structure, and aluminum has corrosion resistance, and ceiling uses the time long, and the density of aluminum is little, light weight, and safe and reliable, production cost is low.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
