Description
Technical field
The present invention relates to a kind of separator, heat insulation and sound insulation especially for roof flat or smooth inclination, this separator is by making with the bonding mineral fibers of adhesive, particularly make by glass fiber and/or ore fiber, and this separator has towards the first surface of face to be isolated with this first surface and extends in parallel ground, the second largest surface that keeps the compartment of terrain to arrange, wherein, these big surfaces interconnect by side surface, these side surfaces are arranged vertically and substantially mutually also perpendicular to described these big surfaces, and described separator has at least one and is arranged in lip-deep coating.
Background technology
Disclose the isolated material of being made by mineral fibers in the prior art, these isolated materials are that title is sold on market with " mineral wool " for example, and show very high temperature tolerance.According to Deutsche industry norm (DIN) DIN 4102-17, these isolated materials have the fusing point more than or equal to 1000 ℃, and they are made by the liquation that comprises mineral, slag and other clouts.These raw material will melt in cupola furnace or tank furnace, and liquation moulding on different defibrators.
When using the general fibre separator, produced the particle of mineral fibers and non-fiber.The particle of thicker non-fiber can most ofly be separated from the mineral fibers stream that generates constantly.In the corpus fibrosum that gathers by mineral fibers, leave account for greatly gross mass 5% to 10%, 〉=particle of 63 μ m, and leave account for greatly gross mass 20% to 30% ,≤particle of the non-fiber of 63 μ m.After the generation of all particles that are generated, they will quench by the water that gasifies at once, thereby make them on the one hand by the sclerosis of vitrifying ground, and be cooled on the other hand so far forth, the adhesive that promptly dissolves in water or disperse can stick rather than be hardened on the mineral fibers.
Generally adopt organic bond, particularly adopt the mixture of phenolic resin, formaldehyde resin and the urea resin of the sclerosis of thermosetting ground.
By additive, for example expand sometimes by polysaccharide for these mixtures.In order not jeopardize the classification of isolated material as the constructional materials of noncombustible construction material or very difficult at least burning, the share of organic bond is normally constrained to less than 4.5% of gross mass, under the situation of the mineral wool isolated material of making according to blowing method (D ü sen-Blas-Verfahren), the share of this organic bond is restricted to less than about 8% of gross mass.
The mineral wool isolated material also can be produced by method commonly used when producing glass wool.A kind of like this production method has special advantage: the particle that does not generate or generate very slightly non-fiber.
Except adhesive, the mineral fibers that is generated by additive by waterproofing work, described additive cause water proofing property on the one hand and produce very little adhesion based on the reformed interfacial characteristics of mineral fibers, the fracture of wire of the meticulousst mineral fibers can be remained on not half.Repeatedly use the high mineral oil that boils for this reason, with oil and water and milkization, seldom silicone oil or silicones.This part share accounts for about 0.2 to about 0.4% of gross mass.
The isolated material of being made by mineral wool is mainly by the production of cascade defibrator.This defibrator allows to be rich in very narrow machining area processing the glass of alkaline earth.But it only can generate very short mineral fibers, and also oneself deforms this in addition mineral fibers by the necessary very high air velocity of the mineral fibers that generates at transporting.This defibrator is arranged in the input of the storage collection chamber of horizontal alignment, is directed into the conveying device end, that air-flow can pass that is arranged in storage collection chamber constantly by air-flow at the indoor mineral fibers stream that generates of this storage collection.Leading on the path of this conveying device, the particle of thicker non-fiber will be separated.Mineral fibers stream is made up of the particle of mineral fibers and non-fiber, and described mineral fibers has been finished waterproofing work by adhesive and additive.The mineral fibers that does not have to carry out waterproofing work by adhesive still betransported.
The gathering and the forming characteristic of the corpus fibrosum that is made of mineral fibers are to influence by being blown into of product chip with polished isolated material particle or isolated material fibers form substantially, and under relatively large situation variation regularly.Thisly can not enter into originally jointing material stream and wadding fibrous admittance that therefore can only just have been formed based on its shape by the isolated material that pulverizes preparation.Adhesive that those comprise within it, that harden also additionally is incorporated into flammable organic material in the corpus fibrosum, and and then is incorporated in the isolated material of being made by corpus fibrosum.
The conveying device that air-flow can pass has filter effect.Mineral fibers exists on the conveying device with certain thickness product with the principal fiber band forms of waterproof thus, and described thickness depends on the power of defibrator and the transporting velocity of conveying device.Usually strive reaching the very little weight per unit area of principal fiber band, although so that can under the situation that adopts minimum cooling media amount (for example water), avoid the sclerosis that shifts to an earlier date of jointing material.And then, this principal fiber band is by reciprocating second conveying device laterally and on the conveying device that accumulates in the 3rd microrunning that mutually tilts stackedly.This make that is described of fabric strip enough thick, waterproof is described to indirect gathering.It also is known directly gathering in addition, wherein, finished the meticulous isolated material flock of the mineral fibers (particle that may comprise non-fiber) of waterproofing work, the fiber that does not contain adhesive and meticulous recovery by adhesive and additive, by downtakes or by from horizontal direction turn to corresponding high storage collection is indoor accumulate to ideal height till or accumulate to necessary weight per unit area on the conveying device in slow running till.By the mode of gathering of this flexibility, it is stacked that mineral fibers will not have specific direction ground flatly to overlap the to each other.
End the fabric strip of most waterproof in the nothing that as directly gathering, is constituted in gathering indirectly, can be compressed to ideal thickness subsequently and be compressed in the hardening furnace subsequently, wherein, after this main vertical upset, between this hardening furnace, have two that arrange up and down mutually, as to transmit pressure conveyer belts.Two conveyer belts of this of hardening furnace are made up of the U-shaped element, these U-shaped elements be fixed on around traction element on and constituted thus not have and ended most band.Have slotted hole and circular hole in the face of the transmission pressure of the element of these stratiforms, hot air can be passed in vertical direction not have and end most fabric strip and be sucked out by these holes.When nothing is ended most fabric strip and is input to hardening furnace, mineral fibers is squeezed into these for example in 5 to the 7mm wide slotted holes and be squeezed in the slit between the individual component especially, and this will cause changing into by the adhesive sclerosis feature contours on two big surfaces not having the fabric strip that ends most isolated material band.
The isolated material band can be divided into plates by length sawing and jack saw, also can be divided into thin slice by leveling saw if desired.
The non-flammable isolated material of being made by mineral fibers, particularly made by mineral wool is widely used in the isolation of particularly light-duty flat-tope structure.In the professional rule of relevant roof structure, the inclination of flat expression deck is smaller or equal to 10 °.This light-duty flat-tope structure often has roof tiles, broad extension and the frivolous profile plate as carrying.Had between the edge of top flange clear span by the sheet material of moulding terrifically until about 172mm.Thisly installed with opposite way sometimes, thereby make the present directed downwards in top flange of broad by the sheet material of moulding, this enlarged now above the bottom flange between clear span.This light-duty flat-tope structure bends under himself load effect, descends crooked doughtily later in the weight of rainwater and snow.Their resonance very easily also can be encouraged easily by the loading of wind in addition.Perhaps thin synthesis material film is applied on the roof tiles as the aeroseal layer that suppresses evaporation, perhaps also can is bonded in the top flange of profile plate or is positioned on the edge of a wing of top with pitch zone that covers by metal level or synthetic rubber band.
The division board great majority are attached to the roof tiles of carrying with the form of larger size panel with for example wide size of 2m length * 1.2m or suppress on the aeroseal layer of evaporation.This large-sized plate has constituted the multi-region supporting body thus, the plate of narrow, perhaps contrast to common small size plate (it is wide that for example it is of a size of 1m length * 625mm) Comparatively speaking, this large-sized plate has obviously higher carrying may.But under any circumstance all to avoid protruding from the sheet material end of bottom flange.Because the size of common division board is different on the distance of top flange and the market, so division board must be by cutting, so that the sheet material seam lays respectively at the centre of top flange.For fear of the cutting work of costliness, flange filler measuring body form fit, the bottom flange upside can be presented in the section bar, and near the sheet material seam of division board can be placed on the described flange filler.
The roof band is fitted on the separation layer that is made of division board or the roof sealing film is routed on the separation layer that is made of division board subsequently.Described roof band or roof sealing film also link to each other with profile plate by threaded fastener as division board.Pressure distribution plate or clamping plate are twisted by threaded fastener and are closed, so that meet material ground power are incorporated into this two kinds of materials.
The isolated material of being made by mineral wool has such advantage: it not can with various encapsulant generation chemical reaction.Do not have the change in size of temperature condition decision by the division board of this isolated material manufacturing, its edge is softer relatively in addition, and these two kinds of advantages have been avoided the influence to encapsulant of mechanical condition decision.These isolated materials are permeable in addition, and this makes water evaporation do not stopped by becoming possibility, and can make moist roof structure soma dry when having enough energy as much as possible.
Opposite with it is, it is out of use roof structure that foregoing flat-tope structure pushes up for for example roof, parking lot or balcony, and described roof structure should only be trampled for the needs of maintenance work occasionally according to the cycle of setting up.Periodically the part surface in for example path (Laufweg) of control will be protected by the layer of the pressure distribution on band or sealing film and the structure of building thereon.It also is feasible that the bearing structure that can bear high capacity is placed on the roof tiles of carrying.Encapsulant and separation layer will be penetrated thus, so just may produce defect point or leak point.
At first consider its compressive strength by the division board that mineral wool is made, wherein will strive generally speaking keeping≤capacity of heat transmission of 0.040W/m K.Division board under the encapsulant should be under the middle pressure load condition have minimum compression CS (10Y) 60 (promptly impact 10% and have 〉=60 kPa) according to DIN EN 13162, and described middle pressure load comes across under the situation that the roof is not used.In order to reach such value of compressive stress, division board must have very high material density and/or have adhesive ingredients.For the use amount that limits necessary material density and employed corpus fibrosum and the weight of division board separately, at the application in the flat-top scope, division board is folded consumingly, and mineral fibers is with precipitous attitude and big surperficial the aligning thus.Improved thus compressive strength, along continuous straight runs laterally and the compressibilty of folding direction, and thermal conductivity.Tensile strength in plate plane, the bending rigidity on the folding direction and on load direction the shear strength perpendicular to the big surface of division board all produced decline.
Under the mineral fibers band situation of making according to known folding mode, by the fabric strip manufacturing with folding direction rectangular and have the highest bending rigidity transverse to the manufactured goods direction of mineral fibers thus.Owing to this reason division board also with this longitudinal alignment ground across the roof tiles that is arranged in carrying by on the sheet material of moulding.The bending rigidity of division board is obviously less on forming direction thus, and therefore a kind of like this danger will raise: under the condition of loading of more frequent parallel and forming direction, isolated material does not have enough supporting capacitys.
Be intended to fold by the power of the fabric strip of waterproofing work and will introduce by the big surface of principal fiber band.Because power affacts on the fabric strip with similar size and Orientation by conveyer belt in hardening furnace, therefore in two big surfaces fabric strip and that make thus and fabric strip and the mineral fibers of two big lower face of manufacturing thus, with respect to in the zone between two big surfaces of division board, quite entirely or at least more entirely point to big surface.This is equally applicable to the insulator material made by the isolated material band.
If the isolated material band flatly is separated into one or more layers, at least one of the big surface of the band of acquisition part by this way is positioned at the zone of isolated material band, and described zone has very little intensity.
In order to make division board have resistance more with respect to the loading of load, and be implemented in simultaneously on sheet material and/or the clamping plate and optimally power be incorporated into separation layer, a kind of like this division board is provided, it has high layer from the teeth outwards.This layer majority has about 150 to about 170kg/m
2Material density, the division board that generates like this has about 180 to 220kg/m thus
3Material density.
The another kind of the supporting capacity of separation layer improves thus and realizes: two high-density layers are staggered to be arranged superimposedly, promptly always high-density layer last and another be placed on the roof tiles of carrying or be placed on suppress evaporation and secluding air layer on.
Because the division board that this sandwich style is arranged is not that power is interconnective ordinatedly, so the supporting capacity of the division board that is made of multi-layer isolation layer does not improve or only not obvious the raising.
Irrelevant with the layout of fiber in division board, the intensity of separation layer is along with reduce (promptly by decline by compression and the folding tension force that causes) by relaxation effect time lapse.This effect is quickened by the load of the machinery that repeats and is amplified.Relate to the influence of water, the hydrodynamics mechanic effect of Shi Fanging can cause the loss of strength of certain degree thus, is used as the consequence of the disintegration of this structure.
The elimination of the consequence of separation layer impaired and/or the moist effect that causes as its supporting capacity loss is quite complicated, and thereby also causes high disposal cost.Existing roof structure defective or that sufficiently do not isolate by additional isolation layer and additional corresponding sealing, is favourable under many circumstances.Wherein existing aged sealing will be removed, and if its water vapor diffusion resistance also not too high, then do not change it or after perforation, depend on the circumstances.The separation layer of slight deformation must have the enough big moment of resistance respectively on two horizontal space axle, the end face that wherein not only must obtain to have bending rigidity also must be by obtaining bottom surface with flexural strength.
For the validity of end face, possesses advantage with compact as far as possible being connected of the mineral fibers of separation layer.Relevant therewith is, bonding possible as the solution proof with organic artificial resin can make the constructional materials grade of division board descend yet do like this.The inorganic adhesive of method employing synthetic materials modification is known as an alternative, yet they are embrittlement very easily, and be difficult to it is added in the separation layer that plays a role as fine filter, made by mineral fibers with enough degree of depth, can only constitute thin layer thus.Thin layer (for example less than 20mm) is too crisp for effectively using here.The thickness of this layer is because its heat bridge effect can not optionally be enhanced on the other hand.
Summary of the invention
Set out by these prior aries, task of the present invention is for regard to its static characteristic particularly with regard to its bending rigidity, also improve this generic separator with reference to its workability simultaneously.
