Definitions
- the invention relates to a building board with a Layer of at least partially with each other associated mineral fibers as well as an open Pore framework between the mineral fibers and their Use.
- Such a building board can be a pure mineral fiber board as well as a composite building board, in which a layer of mineral fibers exists.
- the mineral fibers according to their Extraction from a melt, with admixture of a Binder to a primary / secondary nonwoven prepared, then compacted, in an oven hardened and then to the desired level tailored. The cut can also be made before Curing done.
- mineral fiber building boards known as so-called Lamella plates are called, in which individual Slats were joined together to form a building board.
- a building board all these known components, regardless of the Orientation (orientation) of the fibers, be according to the invention under the term "building board” subsumed. This also applies to the outer Geometry. Usually a building board becomes two plane, having mutually parallel surfaces; it But there are also use cases where this can be different can. For example, a building board could also have a have trapezoidal cross-section or on one Main surface grooved or ribbed formed be. In the latter case, the Term "main surface” is understood to mean that it is the appropriate surface area of the Component acts.
- the compressive strength of a building board hangs other of the gross density, but also of the Fiber orientation off.
- Said lamella plate in which the fibers are substantially perpendicular to the Main surfaces run, has a significant higher pressure resistance compared to one Mineral fiber mat / mineral fiber plate on, in which the Fibers substantially parallel to the Main surfaces or irregular.
- the compressive strength in particular in the sense of Accessibility or trafficability is common insufficient.
- the invention remedy create and offer a building board, the one has improved walkability.
- Composite elements are known in the prior art, in which a mineral fiber layer, for example with a wood wool lightweight board is glued. These Wood wool cover layer increases the surface strength the mineral fiber layer, but requires also a considerable procedural effort. In addition, the product becomes thicker and heavier. The thermal properties change. The same applies if a mineral fiber element with a Plaster layer or the like is provided.
- the invention goes a completely different way, namely based on the following considerations:
- the existing open pore volume between the Mineral fibers in a section below (adjacent) a main surface is used to partially fill it with a hardening material and in this way a variety, more discrete, isolated "reinforcement areas" within the To create pore framework, which is worth mentioning Improvement of the mechanical properties of the relevant section.
- This goal can be achieved with particular advantage, if the Pore scaffolding was previously changed so that (relatively) larger cavities are created, for example, by appropriate mechanical Perforation. In this way you can also do that to bring in said filling material easier.
- the corresponding "filled layer" can be very thin, for example, only a few millimeters, in particular then when the individual filled cavities (Islands) are close together, so only one have small distance to each other.
- the Invention a building board with a layer of at least partially interconnected Mineral fibers and an open pore framework between the mineral fibers, the pore framework, starting from at least one main surface of the Mineral fiber layer, over a section, vertical to this main surface, between 0.5 and 50% of the Total thickness of the mineral fiber layer, at least 10, not more than 90% by volume, with a monolithic, hardened material is filled.
- the filled volume fraction depends essentially on the Size and shape of the filled pores (cavities). For example, if the filled cavities have one Cone shape, with the largest cross section in the range the main surface lies, it becomes clear that the Total degree of filling of the pore volume in each Case is ⁇ 50 vol%, if the individual Wells are arranged at a distance from each other. Just because of the mentioned conical shape results but a particularly favorable increase in Compressive strength, because in the immediate area of Main surface of the proportion of filler too Mineral fibers can be well over 50% and thus a high proportion of directly mechanical acted upon surface by the cured Material is stabilized.
- the main surface coat with said filler possibly in very thin thickness of for example, one millimeter or less, provided this is desired, for example, at the same time an adhesive substrate for a subsequent Plaster coating or a connection to a concrete surface to provide, as described becomes. But even in this case remains as essential feature that below the Main surface following section of the Mineral fiber layer only partially in the form of individual Islands said filling with the hardened Material shows.
- This monolithic cured material may be an inorganic material, for example a SiO 2 based material. Specifically, it may be a cured silica gel. Also conceivable are other inorganic materials such as gypsum, fine mortar or the like.
- the bulk density of the mineral fiber layer not yet filled with the material may for example be between 80 and 100 kg / m 3 , according to one embodiment> 125 kg / m 3 , but also> 150 kg / m 3 . Values up to 200 kg / m 3 and above are possible.
- the mentioned section its open pore volume partially filled with the cured material, usually has a thickness between 0.5 and 10% the total thickness of the mineral fiber layer. Regardless, the absolute thickness, for example between 1 and 15 mm, for example between 1 to 10 mm or between 2 and 7 mm.
- the bulk density of the filled with the monolithic cured material portion is, depending on the filler, for example, between 100 and 400 kg / m 3 , the partial surface load, for example, between 0.15 and 0.25 N / mm 2 .
- the first sub-step becomes specifically discrete Depressions are introduced into the mineral fiber layer, for example, pressed or pressed.
- compulsorily leads to a compression (increase of Bulk density) in the peripheral region of the recesses. This is not only harmless but even beneficial because the subsequently supplied filler now um so less in the areas between the mechanical introduced cavities will / can.
- the filler in the remaining pores between the mineral fibers in the Areas between the depressions usually only penetrate in a completely subordinate part is, especially if the material with a rather pasty consistency is applied. So far Material also in the areas between the Depressions penetrates this is harmless, while according to the invention only a partial backfilling takes place.
- the said tool for introducing the wells may for example consist of a roll of whose surface spikes (spikes) protrude, for example, with a cone geometry, so that the in the surface depressed depressions are conical, with the tip inside the Mineral fiber layer and the largest cross-section in the Area of the main surface.
- the maximum Cone diameter is for example 1 to 3 mm, the length is 3 to 7 mm.
- Can easily 10 to 20 Thorns per square centimeter can be arranged to a dense network of wells in the Surface form.
- the compressive stress of the finished building board should be at least 60 kN / m 2 at 10% compression (in accordance with DIN 18165-1).
- the invention also includes the following use of a described building panel as a cladding element of Concrete elements such as concrete walls, concrete ceilings or Concrete floors.
- the building board creates an appealing Cladding, at the same time a heat and sound insulation, also a fire safety measure. To the To improve the adhesion of the building board to the concrete element It is good if the building board already described Has adhesive base.
- the adhesive bond can be optimized if the filler material in the pores of the mineral fiber layer, such as the concrete, is an inorganic material, for example based on cement, gypsum, fine mortar or SiO 2 .
- connection building board concrete part can also by separate mortar, glue, mineral or other Binders and / or mechanical fasteners like claws, anchors or dowels.
- mechanical parts can be largely dispensed with if the building board used as a lost formwork is, that is the fresh concrete directly on the Plate (s) is poured, especially in ceilings.
- several plates can be combined on the same On-site concrete formwork laid and then with Concrete mortar to be poured over.
- To form a more or less closed sight can the individual building boards on marginal folds or Tongue / spring training are arranged to each other.
- edges of the building board for a be chamfered subsequent filling.
- FIG. 1 shows a cuboid building board 10 which made entirely of mineral fibers.
- the plate includes an upper major surface 12 and a lower major surface Main surface 14 and side surfaces 16, 18, 20, 22nd Extending from the upper main surface 12 extends a section 24 whose thickness "d" about 5% of Total thickness D of the component 10 is. At a assumed total thickness of 50 mm d accordingly 2.5 mm.
- section 24 run a variety of conical recesses 26 (with the pointed end into the device 10).
- the diameter of the Recesses 26 is in the range of Main surface 22 approx. 2 mm.
- the depressions 22 are cured with a Silica gel filled, which partially also zones 28 in Area of the main surface 12 between recesses 26 covers.
- Figure 2 shows schematically that instead of the in Section a) shown conical form the wells 26 also a cylindrical shape (part b) of Figure 2), or for example, a hemisphere shape (part c) of FIG 2).
- the ceiling shown in Figure 3 consists of a Concrete ceiling 100, on one of its underside Variety of mineral fiber panels 120 is covered.
- FIGS 3, 4 show that each building board 120 edge has more folding anchors 160, the on the one hand anchored in the plate 120, on the other hand, they tower above.
- the direct surface connection between plates 120 and concrete 100 is favored by the backfilling a near-surface portion 240 of Plates 120 with a hardened silica gel, which previously, for example, in conical Recesses 260 introduced by means of a pressure roller has been. In this case, even narrow areas 280 between the conical recesses 260 at least partially filled with silica. While the insulation boards have a thickness of about 5 cm have (usual range: 20 - 200 mm), is the Thickness of the layer 240 only 6 mm.
- the partial surface load of the section 240 is 0.2 N / mm 2 .
- the described system is particularly suitable advantageous for garages, passageways, tunnels, Large spaces, precast concrete elements in sandwich construction, double-shell partitions in buildings etc.
