Definitions

  • the invention relates to a wall, in particular a ship's wall, consisting of at least one large-area wall element on which at least one web-shaped element is arranged for stiffening the wall element, which element extends in particular parallel to the surface normal of the wall element, and at least one insulating element which consists of mineral fibers and essentially rests on the wall element with a large surface and engages over at least one web-shaped element.
  • Such walls are known from the prior art. As a rule, these are walls made of metal, in particular steel or aluminum, and made of plastic. Walls of this type are produced from large-format sheets of these materials and, in order to increase their stability, in particular to improve their resistance to dents, have web-shaped elements, for example also in the form of beads. These walls are used, for example, as drop sides or decks of floating bodies, such as ships, drilling platforms or the like.
  • the web-shaped elements can be an integral part of the wall or connected to the wall by fastening means.
  • these bar-shaped elements can be arranged on the large-area wall element by welding, with the aid of rivets and / or by means of adhesives, in a non-positive and positive manner.
  • the web-shaped elements can be profiled differently. In the simplest case, these are, for example, web-shaped elements with a rectangular cross section. Usually, however, those web-shaped elements are also attached to the large-area wall elements, which are L-shaped, T-shaped or double-T-shaped in cross section. In shipbuilding, web-shaped elements are also used, which are referred to as so-called HP profiles. In these profiles, the end of the web-shaped element on the room side is bent in a bead-like manner. In addition to the use of such walls in shipbuilding, such walls can of course also be provided in technical systems. In the following, however, the invention is essentially explained with regard to a ship's wall.
  • Walls in particular ship walls, must be protected against heat loss on the one hand and against the formation of condensation on the other. Fire protection is also very important for such walls.
  • non-combustible or at least flame-retardant insulation elements are primarily used, and their actual suitability as fire protection elements must be proven in corresponding component tests.
  • Glass wool insulation materials are therefore preferably used.
  • Such insulating materials consist of glassy solidified fibers, which are usually bonded with small amounts of thermosetting curing mixtures of phenol-formaldehyde-urea resins.
  • high-boiling mineral oils are distributed in the mineral fiber mass for water repellency and dust binding.
  • Glass wool insulation materials are made from silicate melts that have relatively high proportions of alkalis or boron oxides.
  • a disadvantage of such glass wool insulation materials is the tendency to sinter or melt at temperatures above approx. 600 ° C. Glass wool insulation materials can therefore only resist for a very short time in the event of a fire.
  • a glass melt is mostly defibrated in defibration units that have a rotating, bowl-shaped defibration plate.
  • This defibration plate has perforated walls through which the glass melt emerges due to the centrifugal force and is thereby deformed into mineral fibers.
  • the mineral fibers are impregnated with binders and other additives, for example the high-boiling mineral oils, in a chute located below the defibration plate and collected on a slow-moving conveyor.
  • binders and other additives for example the high-boiling mineral oils
  • Insulating elements made of glass wool are generally produced with bulk densities of less than 45 kg / m 3 , in particular less than 30 kg / m 3 .
  • a mineral fiber web made of glass wool therefore only needs to be slightly compressed in height and its structure to be fixed by curing the respective binder by means of hot air drawn through it.
  • Characteristic of the glass wool insulation materials produced in this way is their relatively high tensile strength parallel to the two spatial axes in the planes of the large surfaces of the insulation materials and the low transverse tensile strength perpendicular to the first two directions. If such insulation elements are subjected to bending, the deformation takes place on the one hand through the corresponding bendability of individual mineral fibers or mineral fiber layers, as well as through relative movements of the mineral fiber layers within the insulation element.
  • the invention is based on the object of developing a generic wall in such a way that fire protection is improved in particular, but the wall also has improved thermal insulation and improved protection against the formation of condensation.
  • the insulating element has a temperature resistance of more than 1,000 ° C according to DIN 4102, part 17 and that the insulating element has a mesh fabric on its two large surfaces, which has a flexibility that the deformability of the Insulation element is not restricted. With such a wall, fire protection is significantly improved.
  • the arrangement of a mesh fabric on each of the large surfaces of the insulating element enables an improved stiffening of the wall, while at the same time there is a deformability of the insulating element, which makes it possible to arrange the insulating element in the area of the web-shaped elements in such a way that it covers the entire wall element and rests on the web-shaped element. This prevents discontinuities in the thermal insulation.
  • the improved fire protection in particular the temperature resistance of more than 1,000 ° C., is achieved with a wall according to the invention in that the insulating element is made of rock wool.
  • the basis for the production of stone wool insulation materials is high-earth alkali, iron oxide-containing Si0 2 -Al 2 0 3 glass melts.
  • the fiber formation takes place on so-called cascade fiberizing machines, with which mineral fibers and non-fibrous particles are simultaneously formed, the non-fibrous particles being predominantly separated.
  • the mineral fibers formed here are very short and, moreover, are also curved.
  • the mineral fibers from a rock melt are also collected directly on a conveying device to form an endless mineral fiber web, a so-called thin primary fleece usually being formed, which is then deposited by a pendulum device transversely to its conveying direction on a downstream conveying direction.
  • This second mineral fiber web is referred to as secondary fleece and is used to manufacture the insulation elements, so that the secondary fleece is continuously deposited on the second conveying device at the required height with regard to the desired thickness and bulk density of the insulation elements.
  • Corresponding insulation elements made of stone wool are manufactured in the form of mats, insulation felts, panels or other shaped bodies.
  • the mats consist of weakly bound mineral fiber masses, which are usually layer are connected.
  • wire mesh mats are known in which a wire mesh is arranged on one surface and is quilted or sewn with the mineral fiber mat.
  • Such wire mesh mats formed on one side with a wire mesh also serve to insulate hot systems and can be used up to temperatures of 600 ° C.
  • Such wire mesh mats preferably have bulk densities of more than 70 kg / m 3 , in particular more than 90 kg / m 3 . Due to the high bulk densities and the connection of the wire mesh with the mineral fiber mat, they are not suitable for the insulation of the walls in question.
  • the insulating element is designed as a particularly elasticized insulating felt.
  • Insulating felts are, for example, mineral fiber webs one meter wide and several meters long, which are usually traded in the form of compressed rolls so that they can be transported and stored in a simple manner.
  • insulation felts also have the advantage that they can be handled in an advantageous, simple manner in the area of limited space, for example in a ship's hull.
  • Insulating felts of stone wool of this type therefore have the advantage that, on the one hand, they have a large area and, on the other hand, due to their rollability, they can be processed in a simple manner even in confined spaces.
  • Insulating felts can be designed with or without a carrier material, ie a carrier layer. If a carrier material or a carrier layer is used, it usually consists of an aluminum foil which is laminated onto the mineral fiber web of the insulating felt. It should only be taken into account here that appropriate aluminum foils are not advantageous in every application, since they can possibly serve as a vapor barrier, so that moisture remains between the wall element and the aluminum foil in the insulating element and can possibly lead to corrosion. On the other hand, the aluminum foils reduce the risk of tearing of the insulating felt when insulating wall elements with small radii of curvature, in particular in the area of web-shaped elements, so that they serve to improve the bending strength of the insulating felts. As an alternative to aluminum foils, the insulation felts can be reinforced with glass fiber fabric.
  • the insulation element has a bulk density between 21 and 35 kg / m 3 , in particular between 25 and 29 kg / m 3 and / or a binder content between 1.5 and 2.7 mass% having.
  • insulation elements with the preferred bulk density and the preferred binder content are sufficiently stable to be able to avoid breaking the insulation elements during assembly.
  • these insulation elements are sufficiently flexible, in particular bendable, in order to apply them to the wall element and the web-shaped elements as far as possible even in the area of the web-shaped elements.
  • the mesh fabric is preferably a fiber mesh fabric made of glass fibers, carbon fibers, plastic fibers, natural fibers and / or wires with little
  • the use of a fiber mesh fabric made of glass fibers, carbon fibers, plastic fibers or natural fibers has the advantage that such fiber mesh fabrics on the one hand have high stability and on the other hand have great flexibility, so that in turn the shape of the insulating element is sufficiently stable and at the same time enables it to bend, which facilitates placing the insulation element on the web-shaped elements.
  • the mesh fabric preferably has a mesh width between 5 mm and 25 mm, the mesh fabric in particular having square meshes with an edge length of 10 mm.
  • the mesh fabric is glued to the insulation element.
  • the mesh fabric can be placed inside the insulation element on the large surfaces of the insulation element and pressed in the hardening furnace before the binder hardens, so that the bonding of the mesh fabric to the insulation element takes place through the binder in the insulation element.
  • the mesh fabric is glued to the surfaces of the insulating element with a supplementary adhesive.
  • the insulation element has a deformability that is constant over its length, width and height.
  • the insulation element in particular the insulation felt, is elasticized by controlled compression and decompression in the direction of the surface normal of its large surfaces and a simultaneous alternating bend.
  • the insulation felt is conveyed, for example, by several roller passes, which on the one hand carry out the required compression or decompression and on the other hand the mutual bending of the insulation felt.
  • the strong compressions and the alternating bends break up firmer areas of the insulation felt, for example also inhomogeneities in the mineral fiber and / or the binder distribution, in order to achieve a uniform deformability of the insulation felt or the insulation elements made from it.
  • the wall element has pin-shaped projections which pass through the insulation element. These pin-shaped projections are nail-like and run parallel to the surface normal of the wall element.
  • the insulation element is put on the pin-shaped projections. This configuration also ensures that the insulation element is in full contact with the wall element even when the wall elements are arranged obliquely or perpendicularly. Additional fastening elements, for example glue, can be dispensed with here, which can only adversely affect the fire protection properties of a corresponding wall anyway.
  • holding plates are placed on the pin-shaped projections, which rest on the insulating element. With these holding plates, the insulation element is also fixed in its position relative to the wall element.
