It is useful for manufacturing modular elements intended for apartment houses and industrial buildings, elevators, sewer pipes, etc.
  • GB 2,155,389 discloses a method of producing a concrete sewerage liner comprising applying a slurry of chopped fibre reinforced concrete onto a rotating horizontal or vertical mandrel.
  • the product obtained by said method may have microcracks reducing the mechanical resistance of the product.
  • An apparatus for manufacturing building structures from a cement concrete mix and glass fibres disclosed in GB Patent No. 1,497,834, Cl. B 29 G 23/12, which is also the closest prior art of the present invention, comprises a rotatably mounted mandrel, spools with fibres, means for impregnating the fibres with resins, pulling means for tensioning the fibres, and means for fabricating a fabric.
  • this apparatus is aligned along a horizontal axis, which is quite suitable in case of impregnating fibres with resin, it becomes absolutely improper when impregnating the fibres with a cement type composition, because the fibres bearing cement composition become hanged down and scaled off the mandrel. At best, it would be possible to apply a single layer of cement composition, but the second one will already scale off.
  • composite panel comprising a foamed plastic core, both sides of the core being covered with one reinforced layer of mortar (hardenable composition), is described in RU 2,102,240, Cl. B 32 B 13/02.

  • the novelty of the invention is that the natural fibres are used, thus allowing to reduce the cost of the end product when working in dry and hot climatic conditions.
  • Further improvement consists in that a layer of a light thermal- and/or sound-insulating and structure-forming material, such as polyurethane foam, is placed between the layers composed of hardenable composition and fibres when applying onto the mandrel.
  • a layer of a light thermal- and/or sound-insulating and structure-forming material such as polyurethane foam

  • the device securing the nozzle for feeding the hardenable composition to be permanently perpendicular to the surface of the mandrel and equidistant therefrom is made in the form of a plane equilateral triangle having its two sides formed by strips of a rigid material, the ends of the strips being interconnected and secured on the guide with the possibility of swinging, and the other ends of the strips are provided with spherical segments, while the third side of the triangle is formed by a strip of a rigid material with a hole, said hole accommodating the nozzle for feeding the hardenable composition, said third side of the triangle being secured in such a manner that the nozzle does not extend outside the external dimensions of the triangle.
  • Such a design of the device allows producing the building structures having uniform wall thickness and homogenous surface, enhanced mechanical strength and performance characteristics.
  • the objective of the invention is finally achieved by providing a building structure in the form of a box section made of a hardenable composition and fibres, said section having rounded opposite faces, said building structure comprising a layer of a light thermal- and/or sound-insulating and structure-forming material, such as polyurethane foam, between the layers of the hardenable composition and fibres.
  • a building structure in the form of a box section made of a hardenable composition and fibres, said section having rounded opposite faces, said building structure comprising a layer of a light thermal- and/or sound-insulating and structure-forming material, such as polyurethane foam, between the layers of the hardenable composition and fibres.
  • this building structure contains fibres in the form of a cellular fabric.
  • Such a structure of the member allows to prevent the layers from shifting with respect to one another, thus allowing the use of such members under overloads and within a wide range of temperatures.

  • the fibre cellular fabric is applied throughout the full height of the mandrel onto the layer of hardenable composition before its hardening.
  • the number of filaments is chosen depending upon the prescribed size of the end product, the desired spacing between the separate parallel filaments of 0.5 to 1.0 cm or the desired mesh size of the fabric of 0.5 cm ⁇ 0.5 cm to 1.0 ⁇ 1.0 cm.
  • a layer of the hardenable composition is applied over the fibres, the direction of applying the hardenable composition being perpendicular to the surface of the mandrel.
  • the formation of the first layer composed of the hardenable composition and fibres is completed.
  • Each successive layer is formed by applying a layer of the fibre cellular fabric on the previous layer of the hardenable composition before its hardening, followed by the applying a layer of the hardenable composition.
  • the number of layers depends upon the required wall thickness of the end product.
  • a device for producing a building structure made of a hardenable composition and fibres comprises a contractable mandrel 1 fitted with detachable flanges 2, the mandrel being mounted on a rotating platform 3 with driving means (not shown), bobbins 4 with fibres wound thereon arranged on a multi-level turret 5, means 6 for tensioning the fibres, means 7 for impregnating the fibres with polymers made in the form of a vertical cylinder having two rows of holes arranged diametrically opposing along its longitudinal axis, means 8 for drying the polymer-impregnated fibres, means 9 for fabricating a cellular fabric having the form of a vertical loom including a shuttle for weft yarn, and means for applying a hardenable composition secured on a carriage 10 mounted movable on a vertical support 11, this latter means comprising a guide 12 carrying a hose with a nozzle 13 for feeding the hardenable composition, a device 14 securing the nozzle to be permanently perpendicular
