Definitions

  • the present invention relates to a fire-insulating wall covering and to a method for preparing same .
  • the present invention relates particularly to a fire-insulating and preferably also sound-absorbing wall covering which meets currently stringent requirements in respect of fire- insulating properties.
  • a fire-insulating wall covering can be applied in tunnels, underground spaces such as shopping centres and the like.
  • Fire-insulating wall coverings known at the present time do not fully satisfy the stringent requirements in respect of fire-insulating properties X
  • these fire-insulating properties mean, among other things, that this wall covering insulates against fire such that on the side of the wall covering remote from the fire the temperature remains relatively low, and particularly below 225 °C, preferably below 200 'C.
  • the wall covering must moreover have good sound- absorbing properties and is asbestos-free.
  • the invention has for its object to provide such a fire- insulating and sound-absorbing wall covering as well as a method for preparation thereof.
  • the wall covering can be applied per se, but is preferably applied as wall covering arranged on a supporting layer, for instance a concrete layer which can optionally be strengthened with a reinforcement . The underlying layers are thus protected against high temperatures .
  • a fire- insulating wall covering comprising a cured mixture of: i) 5-20% by weight mineralized wood fibre; ii) 20-60% by weight sand with an Si0 2 content of less than 5% by weight and a greywacke content of at least 30% by weight; and iii) 20-50% by weight cement.
  • the fire-insulating wall covering is in fact based on a cured cement plate having incorporated therein a specific type of wood fibre and a specific type of sand.
  • the applied wood fibre for inter alia sound absorption is a mineralized wood fibre.
  • a mineralized wood fibre is obtained by bringing wood fibres into contact with a solution of aluminium sulphate.
  • the wood fibres are generally obtained from residual wood which is processed in different steps to form wood fibre with a moisture content of about 15-25% (atro basis) .
  • the aluminium sulphate is added in a quantity of about 2.5% relative to the wood fibre and supplemented with a quantity of water, whereby the moisture percentage rises to about 100% (atro) .
  • the obtained wood fibres, which are thus covered with aluminium sulphate are the mineralized wood fibres applied in the fire-insulating wall covering according to the invention.
  • the applied aluminium sulphate is of standard chemical quality.
  • the sand is a specific sand type since it is less than 5% by weight Si0 2 .
  • the sand further contains at least 30% by weight greywacke.
  • Greywacke is a type of stone containing feldspar, apatite and the like. Clay mineral may also be present. It is a clastic sedimentary rock with a density of for instance 2.6 kg per m 3 .
  • the greywacke can be applied in different grain size distributions (or combinations) , where the grain size distribution is such that the average particle size can be around 1 mm, 4-8 mm, 11-16 mm.
  • the cement used is generally a portland cement, in particular a portland slag cement.
  • the wall covering preferably has a content of mineralized wood fibre of preferably 7-15% by weight, more preferably 10-15% by weight.
  • the fire-insulating wall covering preferably contains 35-50% by weight sand, while the Si0 2 content is preferably lower than 2.5% by weight, more preferably lower than 2% by weight.
  • a fire-insulating wall covering is found to suffice well in practice if it preferably contains i) 10-15% by weight mineralized wood fibre; ii) 35-50% by weight sand with an Si0 2 content smaller than 2% by weight and a greywacke content greater than 50% by weight; and iii) 25-40% by weight cement. The best properties are obtained if in this case the cement is a low-chromate cement.
  • the fire-insulating and fire-resistant properties of the wall covering can be further improved if the mineralized wood fibres and/or the side of the wall covering to be exposed are provided with an impregnation which further improves the fire resistance and/or the durability of wood fibres.
  • an impregnating agent is for instance the impregnating agent described in the German patent application 197 27998.
  • This impregnating agent is preferably applied to the mineralized wood fibres in a quantity of 0.1-1% by weight, more preferably 0.1-0.5% by weight.
  • the fire-insulating wall covering according to the invention can in principle be formed on-site and cured on- site in a mould. It is however also possible for pre-cured plates to be taken to the location of use.
  • the fire-insulating wall covering has an insufficient strength in itself and insufficient bearing capacity, it is recommended to arrange such a fire-insulating wall covering on a supporting layer, for instance a concrete layer or concrete plate.
  • the fire-insulating wall covering can be formed on an already present concrete plate and attached thereto using connecting means.
  • Another option is to arrange finished fire-insulating wall coverings on a prepared support layer using fixing means. Use is made in this case of openings arranged in the fire-insulating wall covering for arranging the fixing means and of plugs of fire-insulating wall covering to cover the fixing means.
  • a good fire-insulating wall covering is generally obtained according to the invention if relative to the cured weight are mixed 5-20% by weight mineralized wood fibre, 30- 60% by weight sand with an Si0 2 content smaller than 5% by weight and a greywacke content of at least 30% by weight; and 20-50% by weight cement, and 10-30% by weight water is then added, whereafter the mixture is cured to form the fire- insulating wall covering.
  • Wall thicknesses of 10 to 500 mm are generally possible.
  • Figures 1 and 3 each show a perspective view of a space provided with a fire-insulating wall covering; and figures 2 and 4 each show a cross-section at the position of details II and IV respectively of figures 1 and 3.
  • This mixture is placed in a mould provided with profiles, recesses for fixing points, rebates and joints.
  • the mass is vibrated, pressed and finally released onto a ground in order to cure.
  • the formed plate is optionally sprayed at this moment with impregnating agent. Such a plate is applied in the embodiment shown in figures 1 and 2.
  • the fire-insulating wall covering according to the invention for curing is arranged, for instance in a curved mould, onto a support layer of concrete already arranged therein. After curing these structural parts can be applied in for instance the embodiment according to figures 3 and 4.
  • preformed fire-insulating wall coverings according to the invention are placed in a mould after being provided with coupling means for coupling to the concrete layer to be arranged. Use is for instance made of wood screw bolts which protrude out of the surface and which will be taken up in the concrete layer to be arranged on this wall covering. Via the coupling means an optimal attachment is thus obtained between the concrete layer on the one hand and the wall covering according to the invention on the other.
  • Figure 1 shows a tunnel 1 provided with a concrete bearing structure 2 with fire-insulating wall coverings 3 according to the invention fixed thereto. Fixing means 4 are covered with conical plugs 5. Wall coverings 3 are mutually separated by a joint 6.
  • Figure 2 shows a detail in cross-section of the structure of this tunnel wall which is provided with wall coverings 3 according to the invention. Wall covering 3 is arranged in the concrete bearing structure 3 using fixing means 4, in this case cotter bolts 7. This bearing structure 3 is further provided with a reinforcement 8.
  • joint 6 is an offset joint which is filled, wholly or only in the two straight joint parts, with a fire-insulating seal 9, optionally a mass of the insulating wall covering according to the invention still to be cured.
  • FIGS 3 and 4 show a pedestrian passage 10, for instance in an underground station. Use is made in this case of wall plates 12 and 13 which are preformed and set up in situ.
  • Wall plates 12 and 13 once again comprise a concrete support structure and a wall covering 14 according to the invention.
  • Wall covering 14 is provided with wood screw bolts 15 onto which is poured the concrete bearing structure 11, which is also provided with a reinforcement 8.
  • the wall coverings 3 and 14 according to the invention are found to satisfy the stringent requirements made in respect of fire-insulating properties.
  • a temperature regime as according to the table below, it was found that on the side of such a 100 mm wall covering remote from the fire the temperature remains below 120 °C, and is even close to a temperature lying between 100 and 110 °C.
