Definitions

  • the invention relates to the construction industry, and more particularly to a method of manufacturing a thermal insulation finishing element for insulating and decorating the external walls of buildings and to a thermal insulating finishing element obtained thereby.
  • the external walls of buildings are insulated by covering them with a suitable thermal insulation material, such as polystyrene foam panels or thermal insulation wool, which are then covered with a desired finish such as plaster, clinker tiles, granite, marble, aluminum or others.
  • a suitable thermal insulation material such as polystyrene foam panels or thermal insulation wool
  • the thermal insulation material is attached to the external surface of the building with glue or pins or in combination of both methods.
  • European patent No. EP2675962 describes the construction, production and installation methods of a thermal insulation product for the insulation and finishing of the external walls of buildings.
  • the product of the invention consists essentially of two elements: a thermal insulation material and a finishing board.
  • the finishing board can be made of ceramic, plastic, wood, glass, metal, aluminum, granite, natural stone, marble, laminate and other materials suitable for finishing.
  • the thermal insulation material is a polyurethane or extruded polyester board, the outer side of which is covered with a finishing board, glued to the thermal insulation board with a polyurethane adhesive covering the entire inner surface of the finishing board.
  • the final product thus obtained - a thermal insulation board with an external finish - is attached to the outer wall of the building with either glue or pins.
  • a facade element especially a board, consists of an external lining layer joined with a plastic insulating layer.
  • the insulating layer is shaped from formed polyurethane foam and is integrated with the external layer, while inside the insulating layer there is a mounting assembly in a form of a grip supporting structure containing minimum one section with transversely connected bars. Each section, at least on its one end protrudes beyond the outline of the facade element.
  • the shaped facade element is a self-supporting structure.
  • the facade element is shaped in an initially prepared mould. The grip supporting structure is placed on the external layer, next polyurethane foam is poured into the mould, the mould is closed and the polyurethane hardens; then a readymade self- supporting facade element is taken out.
  • the invention describes a prefabricated composite building panel for attachment to a vertical wall of a building comprising a rigid sheet of cellular polymeric material having an outer face for facing outwardly of the wall and an inner face for facing inwardly of the wall, a plurality of rigid facing elements embedded in the outer face of the sheet so as to define an outermost surface of the panel, the facing elements being attached to the outer face in a pattern defining spaces between at least some of the facing elements and adjacent ones of the facing elements, a covering layer on the outer face of the sheet in the spaces and mechanical support means engaging the sheet and formed from a rigid material different from the cellular polymeric material and engaging a plurality of the facing elements to provide mechanical support of the facing elements to resist downward sagging of the facing elements on the sheet.
  • the closest prior art for realization of a thermal insulation product for insulation of the external walls of buildings is described in Lithuanian patent No. 6693 owned by an applicant of the present invention.
  • the invention describes a thermal insulation finishing element for fixing to the outer wall of a building, where the finishing layer is formed directly on the outer surface of the thermal insulation board.
  • the method according to this invention is realized by creating a cement mixture with special properties, which, using a special technology, is inseparably connected to the thermal insulation board.
  • a thermal insulation finishing element is obtained, which has an integrated 8-15 mm thick decorative finishing layer with a surface imitating marble, natural stone or other decorative finishing.
  • the thermal insulation finishing element is attached to the external wall of the building both mechanically with pins through appropriate perforated metal strips attached to the inside of the thermal insulation finishing board and with the usual adhesives for attaching polystyrene foam to the external wall of the building.
  • the object of the present invention is to improve the previous method of manufacturing a thermal insulation finishing element, which would include a technology for the production of a thermal insulation finishing element with integrated elements for its fastening to a building facade.
  • a plurality of perforated metal strips are first inserted into the thermal insulation board, which is preferably a polystyrene foam board, for fixing the final formed thermal insulation finishing element to the building facade.
  • the perforated fastening strips are inserted across the thermal insulation board and are directed diagonally downwards from the upper edge of the inner side of the thermal insulation board over the entire thickness of the thermal insulation board.
  • Several such perforated fastening strips are inserted over the entire length of the thermal insulation board and their number depends on the length of the thermal insulation board.
  • Perforated fastening strips for fastening the thermal insulation finishing element to the wall of the building facade are inserted so that their inner and outer ends remain partially protruding on opposite inner and outer sides.
  • the protruding ends of the perforated strips are folded so that the inner end of the perforated fastening strip faces vertically upwards and the outer end of the perforated strip faces vertically downwards, covering a part of the outer surface of the thermal insulation board.
  • the thermal insulation board is now ready to be covered with an outer finishing layer.
  • a special cement mixture consisting of cement, sand, basalt fiber, various pigments, a hydrophobic additive, an air removal additive, a plasticizer, is added to the mixer.
  • the mixer is switched on, and water and plasticizers are added to the mixture.
  • the resulting mass is poured into special paraffin-coated PVC moulds corresponding to the shape of the thermal insulation element and having the desired relief of the outer surface of the thermal insulation element.
  • the mould with the mixture is placed on a vibrating table and vibrated.
  • a thermal insulation element with already inserted perforated fastening strips is placed in the mould on the vibrated mass, and the lower surface of the board, which is at the same time the outer (facade) surface of the thermal insulation finishing element, is connected with the mixture by means of a pressure.
  • the product is dried in the mould, then removed from the mould and finally dried.
  • thermal insulation finishing element one surface of which is inextricably joined with the cementitious mixture forming the outer decorative finishing layer without the use of any additional intermediate polyurethane adhesive, and the opposite surface has protruding ends of perforated fastening strips designed for fastening the thermal insulation finishing element to the facade of the building.
  • Selecting the appropriate pigments results in decorative finishing layers of the thermal insulation element in different colours and patterns, imitating, for example, marble, natural stone or other decorative finishes.
  • the cementitious mixture of the present invention pressurized with a thermal insulation element, acquires the properties of a monolith in the final product, becoming resistant to mechanical and atmospheric-temperature effects, while giving the exterior of an insulated building an aesthetic decorative appearance.
  • the thermal insulation finishing element obtained by the method of the present invention is fastened to the outer wall of the building mechanically by means of pins through corresponding openings in the inner ends of the perforated metal fastening strips pierced transversely through the thermal insulation element.
  • the outer ends of the perforated fastening strips under the finishing layer are folded vertically downwards, partially embracing the thermal insulation element and ensuring its reliable pressure on and nonseparation from the building facade.
  • the object of the invention is to produce a thermal insulation finishing element with integrated elements of its fastening to the external wall of a building.
  • thermal insulation finishing element refers to a thermal insulating board, usually in the shape of a rectangular parallelepiped, having integrated elements for its attachment to the wall of the building, and a decorative layer on the outer surface facing the viewer.
  • the thermal insulation finishing element 1 comprises a thermal insulation board 2, preferably a polystyrene foam board, having the integrated perforated metal strips 3 for attaching the thermal insulation finishing element 1 to the exterior wall of the building, and a decorative finishing layer 1 covering the surface of the thermal insulation board 2 facing the viewer.
  • the perforated fastening strips 3 are pierced across the thermal insulation board 2 and are directed diagonally downwards from the upper edge of the inner side of the thermal insulation board 2 over the entire thickness of the thermal insulation board 2 towards the outer side of the thermal insulation board 2.
  • Several such perforated metal strips 3 are inserted over the entire length of the thermal insulation board 2 and their number depends on the length of the thermal insulation board 2.
  • the distance a between adjacent perforated fastening strips 3 would be between 30-40 cm, and the distance b from the lateral perforated fastening strips 3 to the side edge of the thermal insulation board 2 would not exceed 20 cm.
  • the perforated metal strips 3 are pierced across the thermal insulation board 2. They are directed at an angle of approximately 45° from the upper edge of the inner side of the thermal insulation board 2 down the entire thickness of the thermal insulation board 2.
  • the perforated fastening strips 3 are intended for fixing the thermal insulation finishing element 1 to the wall of the building facade and are inserted rated so that their inner ends 3a and outer 3b remain protruding on opposite inner and outer sides of the thermal insulation board 2.
  • the length of the end 3a of the perforated fastening strip 3 is about 50 mm and the length of the end 3b is about 80 mm.
  • the protruding ends 3a and 3b of the perforated fastening strips 3 are folded so that the inner end of the perforated fastening strip 3a for fastening to the building wall is directed vertically upwards and the outer end 3b of the perforated fastening strip is directed vertically downwards and pressed against the outer surface of the thermal insulation board 2.
  • the part 3c of the perforated fastening strip 3b is bent at a right angle to the inside of the thermal insulation board 2, thus engaging with the thermal insulation board 2. This method of mounting the perforated fastening strips 3 ensures reliable fixation of the thermal insulation finishing element 1 and its pressing against the external wall of the building.
  • the thermal insulation board 2 is forwarded to the next stage, i.e. for forming a decorative finishing layer 4 on the outer surface of the thermal insulation board 2.
  • a special mixture has been created to form the decorative finishing layer 4, the components of which consist of:
  • the finishing layer is formed on the thermal insulation board 2 in the following way: the components of the cementitious mixture are added to the mixer in the proportions given above. When the mixer is switched on, water is added in amount from 8 to 9% w/w of the cementitious mixture. The mixture is stirred up for 10 to 15 minutes until a homogeneous mass of the mixture is obtained. The resulting mixture is poured into PVC moulds, coated beforehand with a paraffin mixture. The PVC mould with the mixture is placed on a vibrating table and vibrated for 30 to 90 seconds, preferably up to 60 seconds.
  • a pressure of 0.4-1.0 MPa the thermal insulation board 2 is joined with the cementitious mixture and left to dry at a temperature of 20-22°C and a humidity of 70-90% for up to 24 hours.
  • the product is removed from the mould and finally dried to give a thermal insulation finishing element 1, shown in Fig. 1 , with an integrated 8-15 mm thick decorative finishing layer 4 covering the outer ends 3b of the perforated fastening strips 3.
  • the decorative finishing layer 4, formed on the outer surface of the thermal insulation board 2, achieves monolithic properties resistant to mechanical and atmospheric or temperature impacts, while providing an aesthetic view to the facade of the building covered with thermal insulation finishing elements 1 of the present invention.
  • the thermal insulation finishing element 1 is fastened to the outer wall of the building mechanically by means of pins through the respective inner ends 3a of the perforated fastening strips 3.
  • decorative finishing layers 4 of different colours and patterns are obtained, having a surface imitating marble, natural stone or other decorative finishes.
  • the invention is described with reference to a method of manufacturing a rectangular parallelepiped-shaped thermal insulation finishing element having only one decorative surface. It is obvious that the method can be equally applied to the production of other forms of thermal insulation finishing elements with a decorative coating applied to more than one surface of the same thermal insulation element and intended, for example, for insulation and decoration of the external corners of buildings.
