Definitions

  • the invention relates to an anti-bullet Door leaf or wall element with ballistic textile fabric.
  • armored plywood is a melamine resin-impregnated plywood with a high density of approximately 1,400 kg / m 3 .
  • Good ballistic properties or good bullet resistance are offset by a number of disadvantages that reduce the usefulness of such an armored door.
  • a door with such a door leaf is very heavy, which necessitates appropriate measures on the door frame side and the hinge side, and the stamina, which is understood to mean the warping of the door under temperature differences, as well as sound insulation and fire resistance.
  • the invention is therefore based on the object to create a door leaf which the said Does not have disadvantages and good door properties combined with high bullet resistance.
  • a similar The task is for bullet-resistant wall elements for the formation of lightweight walls, which like a door - also good sound and fire protection properties with light and inexpensive construction, and possibly also climatic protection, if possible should combine high bullet resistance.
  • the task is at a door leaf or Wall element of the type mentioned with the characteristic Features of claim 1 solved.
  • a door leaf or a wall element is created, which due to the fiberboard core or foamed Kerns can offer very good noise and fire protection and with the double-sided armor of the core with the ballistic Sheets high, from both sides equally effective bullet resistance.
  • the relatively soft Fibreboard material or foamed material results besides sound insulation, good energy absorption of deformations of the fabric and thus supports the bullet resistance.
  • the relatively soft core forms also a trap for projectiles, which the one Armor has penetrated and reduces their energy before hitting the second armor.
  • the rigid outer element gives the door leaf or the wall element a high level of stamina and thus allows use of the relatively soft core with that also for the Door formation or wall formation as soft-looking textiles Sheet.
  • an air gap is preferred inside the core to increase sound insulation and to enable increased core deformation when bombarded, what in interaction with the textile fabrics the bullet resistance increases. It is further preferred if the fiberboard of the core made of non-combustible or only hardly combustible material is formed, e.g. out Mineral fibers or fire retardant treated natural fibers, e.g. coconut fibers. When using foamed material is e.g. Foam glass preferred.
  • the ballistic adjoining the core Textile fabrics are preferably a fabric from highly tear-resistant fibers, in particular from aramid filament yarns, which as such tissue or as coated with a thermoset, thermoplastic or elastomer Prepreg or as a laminate developed from the prepreg can be used.
  • the rigid outer element is preferred Made from a wood-based material, whereby for high stamina hard wood fiber boards are preferred.
  • a special climate resistance of the door leaf or wall element increased climate class
  • thin metal insert e.g. between textile fabrics and in the outer element or in this outer element be provided, this thin metal insert the bullet resistance has practically no influence or this is not intended to be metal armor.
  • FIG. 1 shows a view of a door leaf 1, the edge band 5 and the lock timbers 6 being indicated by broken lines in the figure.
  • a vertical cross-section along the line AA through the door leaf 1 is shown in FIG. 2, the sectional representation for a better graphic representation showing the individual layers of the door leaf in a scale that is not to scale.
  • the door leaf 1 has a core 2, which is formed from a fiberboard material.
  • the core 2 is formed by the fiberboard 2 'and 2 ", which form an air gap 10 between them.
  • the air gap 10 can be ensured by spacers (not shown), for example cardboard strips.
  • the core 2 consists of two fiberboard
  • the core 2 could also consist in one piece of a correspondingly thicker fiberboard or of more than two fiberboards. Accordingingly, there can be no air gap 10 or at most more than one air gap 10 can be provided in the case of several panels.
  • the fibrous core 2 is made of a fiberboard material
  • the resulting relatively soft core forms, on the one hand, good sound insulation, which is further increased by the preferred air gap 10 and, on the other hand, forms a catchment area for projectiles, which interacts with the actual armor in a manner to be described is preferably mineral fiber boards.
  • non-combustible mineral fiber panels can have, for example, a density in the range from 250 kg / m 3 to 320 kg / m 3 and preferably a density of approximately 280 kg / m 3 and, for example, a thickness of 16 mm or, in another example, a thickness of 21 mm.
  • the preferred use of non-combustible mineral fiber panels gives the door leaf a high level of fire resistance, although this can be, for example, a fire resistance T30 for a door panel with 16 mm thick mineral fiber panels in accordance with the Swiss fire protection regulations of the Association of Cantonal Fire Insurance Companies (VKF) or the corresponding CEN standard.
  • mineral fiber boards which term also includes glass fiber boards in the present case
  • other relatively light fiber board materials can also be used, for example fiber boards made of natural fibers, such as coconut fibers. These fibers, too, provide good sound insulation, in particular with an air gap 10, and interact with the armor to be explained in the fire resistance. In the case of such fiberboard, it is preferred if they are made fire-retardant by a known treatment.
  • boards made of foamed materials can also be used, which preferably have a similar density and are not combustible or are difficult to combust.
  • the foamed material is preferably foam glass, but all other foamed or foamable materials are also included in the term.
  • a textile fabric 3 is provided, which as Armor against shelling is used.
  • textile Fabrics which e.g. in the form of a fabric, Knit or braid can be known. It becomes highly tear-resistant plastic or carbon fibers to the corresponding textile fabric processed.
  • prepreg material Through a coating with a plastic material is made from the woven or knitted fabric or braid a so-called prepreg material, which the Can facilitate handling during use.
  • Prepregs can be processed into a laminate, what is known.
  • a coated fabric 3 ie a so-called prepreg used, being a preferred example the material Ultrax® WO 9116 from Verseidag-Indutex GmbH, Krefeld, Germany, is used, whereby it is an elastomer-coated fabric made of different highly tear-resistant fibers.
  • This tissue has a thickness of approx. 5.15 mm and is in the Example shown as a single layer as a textile fabric 3 used on both sides of the core. Of course it would be also a two or more layers on both sides of core 2 possible. However, it has been shown that by combining the material mentioned with the soft core 2 already with one layer 3 on each Side of core 2 a high bullet resistance can be achieved is.
  • the textile fabric 3 on both Sides of the door in the direction of fire before and after the core 2 is arranged, result for the shelling in the Usually symmetrical relationships, i.e. the door leaf points the same bullet resistance from both sides; it is but of course also possible due to the asymmetrical arrangement or thicknesses of layers, e.g. on the one hand the core one Layer 3 and on the other hand the core two layers 3 different Bullet resistance for the direction of fire to achieve.
  • the textile fabric 3 is on both Sides of the core preferably beyond and up to this introduced into the edge band 5, as that of Figure 2 and is also apparent from Figure 3. It follows from this on the one hand, protection of the edge band 5, which e.g. out Hardwood exists, and on the other hand an attachment option of the fabric on the edge band 5, e.g. by Bonding.
  • the fabric 3 is further preferred attached to the core 2 by gluing, this gluing can only be partial or essentially full.
  • the rigid flat element 4 is preferably made of a material containing wood, preferably hardboard.
  • hardboard or hard wood fiber are understood to mean wood fiber boards with a bulk density of more than 800 kg / m 3 .
  • Medium-hard wood fiber boards (MDF / medium density fibreboard) with a bulk density between 350 kg / m 3 - 800 kg / m 3 can also be used for the rigid flat outer element 4.
  • the rigid flat element 4 is constructed on both sides of the core from two wood fiber boards 4 'and 4 ".
  • the thickness of the fiberboard is, for example, 8 mm when using a plate on each side of the door leaf or, for example, two times 4 mm or two times 3.2 mm when using two plates.
  • Figure 3 shows the corresponding structure in a horizontal section along the line B-B of the figure 1, the lock wood 6 also being visible in this figure which is part of the core in this case 2 forms and of the textile fabric 3 on both Sides is covered.
  • a door leaf according to the exemplary embodiment of the invention shown has a density of approximately 680 kg / m 3 , which offers a significant reduction compared to the density of the armored plywood mentioned at the beginning.
  • the door leaf nevertheless has the bullet resistance specified in FB4 and offers high climatic protection and sound insulation as well as great fire resistance (T30) as well as heat protection and burglary protection.
  • the same properties can also be achieved by a wall element for the lightweight construction, which is constructed in the same way as described using the example of the door leaf, in which case the lock wood 6 can of course be dispensed with in such a case. This results in light wall elements which nevertheless have a high resistance to shelling on both sides, which is identical from both shelling directions due to the shown and preferred symmetrical structure of the wall element or the door leaf.
