Description

The insulating panel that is used for temperature compensation
Technical field
The present invention relates to a kind of " interlayer " type insulating panel, the insulation materials core that wherein is generally syntactic foam plastics is inserted between two surfaces of being made by metal sheet.
Background technology
These panels are used in the structure of the roof in building, precast construction, industrial house etc. and wall usually.
Influence is such fact by the problem of the insulating panel that syntactic foam plastics is made: they have low refractoriness, because the high temperature relevant with fire causes the metal surface of insulation foam and panel to be thrown off, bring some disadvantageous result.
In fact, under these situations, the mechanical performance of panel sharply reduces, this no longer shows as a monomer because of panel: the result be it by metal sheet make, ribbing or fretwork are not complementary with the central core of insulation foam with the surface that increases its bending stiffness greatly usually, collapse thereby in building structure, have with such panel construction.
In order to alleviate this situation, learn a kind of composite panel by International Patent Application WO/9921712 under processing plastic Co., Ltd (Process PlasticsLimited) title, its outer surface is by making based on the thermoplastic of anti-retardant polyester or Merlon; Between these surfaces, insert the insulating core of making by phenolic resins.
In order to strengthen the flame breakthrough barrier, in this panel, between external surface and insulation foam, lay a glassy state layer.
The defective of considering before this panel can alleviate relevant with panel deformation, this panel has the surface of being made by metal sheet; Yet, obviously having the surface that is made of plastics, it can not have and the identical mechanical performance of metal decking (obviously with regard to equivalent size), as rigidity or other.
Summary of the invention
Therefore the present invention's technical problem of being intended to solve is to produce a kind of sandwich type panel, and this panel has the external surface of being made by metal sheet, and can alleviate above defective with reference to the prior art state description.
The idea that addresses this problem is to produce a kind of panel, and this panel can compensate the fuel factor that is produced when standing the big temperature difference very on its surface, improves thus in the tolerance that has under the condition of a fire condition.
A kind of like this panel is characterised in that, between at least one and insulation materials core of metal surface, lay a kind of cushion of mineral wool: this pad in fact constitutes a fibrage, can be absorbed in the slippage that in the latter's plane, occurs between insulating core and the metal surface, and can thermal protection core itself.
Such panel construction makes and might use for insulating core: syntactic foam plastics, the usual conditions of deformable and combustible material promptly have bonds well and adaptive capacity under to(for) panel surface; And the rigid batten of nacrite or another kind of material, these laths have the performance that falls far short with surperficial performance.
According to a preferred embodiment of the present invention, mineral wool has 40 and 200kg/m 3Between density and the thickness of insulating core 10% and 50% between thickness; This thickness will depend on various factors, as the type of the insulation materials selected, the size of panel, the existence at one or two surface mineral wool, the service condition of panel, the fire-resistant degree of requirement etc.
Description of drawings
By with in the accompanying drawings the expression the relevant following description of non-limiting example of the present invention, will understand other feature and advantage of the present invention, wherein:
Fig. 1 is the axonometric projection according to a kind of first panel of the present invention;
The cross section of the panel of Fig. 2 presentation graphs 1;
Fig. 3 represents the cross section of a kind of second panel of the present invention;
Fig. 4 is the axonometric projection of the 3rd example of panel of the present invention.
The specific embodiment
If can from figure, see like that, wherein whole sandwich type insulating panel is by 1 indication, has two visible surfaces 2 and 3 of being made by metal sheet; The metal of such plate can be steel, copper or aluminium.
In this case, be that the surface 2 of upper surface has and other high trapezoidal ribs 5 staggered than riblet by 6 indications with reference to accompanying drawing, and be that the surface 3 of soffit only has light rib 7 in the drawings; Such rib is known in the present technique field, and does not therefore need more detailed explanation.
Adjacent with the upper surface 2 of panel, an insulation materials core 10 is arranged, the synthetic resin of Peng Zhanging typically, this resin can be polyurethane, phenolic aldehyde or some other resin; This material also allows the complete filling of the inner space of darker rib 5 really.
Yet, as hereinafter become clearer, insulating core 10 also can be made of nacrite or the rigid batten with other similar material of good heat-proof quality.
Yet, between the soffit 3 of core 10 and panel 1, be furnished with cushion of mineral wool 12; The latter preferably has 40 and 200kg/m 3Between density, and the pad thickness S cBe maximum ga(u)ge S at panel 1 p10% and 50% between.
By adhesive cushion of mineral wool 12 is fixed on the soffit 3, syntactic foam plastics 10 is expanded with itself known suitable type, as occurring usually in the conventional panel like that, thus the production panel.
By this way, pad 12 is locked between the soffit 3 of cellular insulation core 10 and panel: yet, because its characteristic is filled up the fuel factor of 12 compensating actions on the metal sheet that forms soffit 3.
In order to strengthen this result, according to a preferred embodiment of the present invention, the fiber of mineral wool mainly is parallel to the surface orientation of panel; Perhaps, fiber is directed on the direction of part and its traversed by, that is to say, is being directed basically with on the perpendicular direction of soffit 3.
By narration so far, thereby might understand the problem how panel 1 solves formation basis of the present invention.
This is owing to the existence of cushion of mineral wool 12, though it make when between soffit 3 and another surface 2, having high temperature gradient, for example because solar radiation or because the fire of above further explanation, the also possible fuel factor of absorption on soffit 3.
Therefore draw thus, under such condition, the tension force that produces in panel can not cause the disengaging of its element of occurring in the prior art, thereby it keeps its initial machinery and physical property basically; Obviously, under the situation that fire is arranged, these performances remained unchanged in a period of time, and this time is depended on the period that is exposed to flame.
In the present context, should observe, cushion of mineral wool 12 has been finished various tasks.
Main task is to create a thermodynamic barrier, the insulating core with low refractoriness 10 that protection is made by syntactic foam plastics under the situation that fire is arranged.
Second task is that it is absorbed in different heat effects between soffit 3 and the insulating core 10, because as described above, it is not delivered in the stress in the plane of panel; In fact, because the relative slippage of expansion of metal is dissipated in the group of mineral wool fiber, and can not arrive insulating core.
The 3rd task is that it can absorb the bending of soffit 3 when soffit 3 is crooked as the result of its thermal expansion.
Pad 12 in fact is compressible in certain limit, thereby when the metal sheet of the soffit 3 that forms panel is crooked (making progress with reference to Fig. 1 and 2), pad absorbs its distortion and can not produce significant stress in the remainder of panel: obvious this effect depends on fills up 12 thickness and the density that forms its mineral wool.
In this case, should emphasize, the part (from 10% to 50%) that only occupies like that the thickness of whole front panel that cushion of mineral wool if can be seen, so that avoid condensation problem in panel, these problems can be observed in the panel that its insulation is all made by mineral wool.
And, like this insulating properties of the panel of producing, than equal thickness but to have all the insulating properties of panel of the insulating core that is formed by mineral wool superior.
That yes is possible with respect to disclosed content modification of the present invention so far.
Below the various materials that can be used for insulating core 10 are described, hereinafter will refer again to this.
Although be noted that then pad 12 is adjacent with soffit 3 in the panel of Fig. 1 and 2, because this scheme undoubtedly is the simplest, it also can be laid on the upper surface 2, and mineral wool is inserted in the rib 5.
And, also can make two cushion of mineral wool adjacent with two surfaces of panel respectively; This scheme is illustrated among Fig. 3, and Fig. 3 shows the cross section according to second example of a kind of panel of the present invention.
In this drawing, identical label is used to refer on structure or function those the equivalent elements with first embodiment, and each of label is added 20; Thereby panel as a whole is by 21 indications, and its upper surface is by 22 indications, and soffit is by 23 indications, and insulating core is indicated by 30, or the like.
If can see like that, this second panel is symmetrical with respect to its middle plane, and two cushion of mineral wool 32 surperficial 22 and 23 adjacent with it, that make according to the identical standard of above explanation are housed.
Only it is pointed out that in this case, will be two pad integral thickness of 32 the panel gross thickness 10% and 50% between.
Insulating core 30 can be made by polyurethane or phenol formaldehyde foam, and it is applicable to the same insight of above narration; Yet, as to its a kind of replacement, the symmetric form of panel and basically the surface on plane make and might use lath nacrite or extruded polystyrene or expanded polystyrene (EPS).
In similar modification, lath will replace the syntactic foam plastics as insulation materials wholly or in part, and fill up 32 by means of adhesive to lath, as occurring for external surface 22 and 23.
Be understood that in this case, panel also makes might obtain the advantageous effects identical with first embodiment, although it is heavier when lath is made by nacrite.
Should emphasize at last, can improve performance, so that make its sound insulation according to panel of the present invention.
For this purpose, should be with reference to Fig. 4, it shows the panel (having used identical label for simplicity) of image pattern 1 from the below, and wherein soffit 3 is provided with a plurality of through holes 9.
Through hole 9 has 2 to 4mm and be preferably the diameter of 3mm and from 4 to the 6mm spacings that are preferably 5mm; Under any circumstance, ratio sky/reality should be about 33%.
This makes the advantage of sound absorption performance with mineral wool 12, and the mineral wool of arranging adjacently with perforated surface 3 12 provides the decay by the sound in hole 9.
As last a kind of modification, be noted that the present invention also is applicable to curved panel, promptly not picture those flat panels of expression in the drawings; This is the important results that derives from the pad that uses the material such as mineral wool, this pad with for the possible various configuration no-floats of panel.
Yet above-mentioned modification is all in the scope of following claims.
