Definitions

  • the present invention relates to a profiled element for supporting a frame, a method of supporting a frame and a building structure.
  • Buildings which are intended to be occupied by humans typically have an indoor temperature of about 15°C - 22°C.
  • a significant portion of the total energy consumed by a typical building is used for heating the building, i.e. keeping the indoor environment in the above-mentioned temperature range.
  • Such energy efficient building methods typically involve reducing the amount of heat escaping from the building via the walls, windows, doors, roofs etc. Since the heating for buildings is very often obtained by the burning of fossil fuel or similar non-renewable energy sources, a reduction of the heating loss will, apart from reducing the operating cost of the building, also reduce the negative impact on the environment caused by the emission of CO 2 .
  • a modern building structure which is constructed according to an energy efficient building method has a wall structure which is made up of an inner load-bearing structure made of e.g. wood, steel, concrete or other similar rigid and durable material.
  • Load-bearing materials typically have low thermal insulation properties, i.e. high heat conducting properties.
  • any load-bearing material which is located directly in-between a cold outdoor environment and a warm indoor environment so that a temperature gradient is established through the load-bearing material will contribute to conduct heat energy from the warm environment to the cold environment and thus result in increased energy used for heating, i.e. increased heating costs.
  • increased energy used for heating i.e. increased heating costs.
  • the inner load-bearing structure is covered by an outer insulating structure made of e.g. mineral wool, foam or other similar insulating materials.
  • Insulating materials have a low thermal conductivity and are thereby capable of defining a thermal gradient between a cold environment and a warm environment, i.e. between the inner and outer surfaces of the insulating structure. In other words, the insulating bearing material will prevent heat energy from being conducted from the warm environment to the cold environment.
  • insulating materials are typically flexible and non-rigid and therefore typically non-load-bearing.
  • the outer insulating structure is in turn covered by a facade of a substantially rigid material for protecting the insulating material from wind, rain and dust etc.
  • openings exist in the wall structure for allowing air, light, goods and people to enter and exit the building.
  • Such openings may be covered by windows, panels and/or doors.
  • Most modern windows, e.g. 3 pane windows, and modern doors, such as security doors, have excellent thermal insulation capabilities.
  • the insulation capability of windows and doors may in many cases be comparable to the insulation capability of the insulating structure of the wall.
  • the windows and doors are typically provided in frames which are mounted within the opening of the wall structure.
  • the windows and doors must be mounted so that the frame is juxtaposing the insulating structure.
  • the frame should not be located adjacent the load-bearing structure since it would result in the load-bearing structure being exposed in the vicinity of the opening.
  • Such exposure of a non-insulating building part, i.e. the load-bearing structure, to the environment outside of the building is known as a thermal bridge since it will allow heat from the inside environment of the building to quickly escape to the outside environment of the building bypassing the insulating structure.
  • elements such as beams or the like are used for holding the window at an outwardly oriented position while still being fastened at the load-bearing wall.
  • US 6,941,699 discloses a structural support for windows.
  • the structure includes horizontal beams 46 for supporting the window and allowing the window to be moved outwardly.
  • US 4,850,168 discloses a frame assembly for windows etc.
  • the frame assembly has an insulating core, however, it does not allow the window to be positioned in an outwardly oriented position.
  • US 6,922,958 discloses a window unit which does extend outwardly, however, the window unit is fastened by nails or screws to the outer surface of the wall.
  • US 6,182,405 discloses a window frame structure for a wall.
  • the wall has an inner supporting wall structure and an outer non-supporting wall structure and the window frame is fastened directly onto the inner wall structure.
  • US 2003/0041537 discloses a window and wall assembly.
  • the window frame is mounted on the exterior side of the exterior wall.
  • the window is fastened by screws.
  • US 6,293,049 discloses a method for installing a window assembly.
  • the window assembly is located at a junction between an inner wall and an outer wall.
  • EP 2096248 , EP 1806469 and DK 176245 disclose a window structure with a mounting bracket for connecting the frame of the window to the wall opening.
  • the bracket is made of metal.
  • WO 2006/004560 discloses a window frame.
  • the window frame has an L shaped profile abutting against an insulation.
  • US 4,958,469 discloses a window flange.
  • the flange seals between the wall and the frame of the window.
  • connection profile element of thermoplastic material The element is attached to a wall and has an L shape, however, the window is inwardly oriented.
  • U1 discloses a window bracket to be mounted in an opening in a wall.
  • the frame is intended to position the window in an outwardly orientation.
  • U1 discloses a bracket system for supporting a window.
  • the bracket system comprises a bracket fitting for supporting a window frame.
  • metal seems to be the most commonly used material for the purpose of supporting window frames and door frames at an outwardly oriented position adjacent the insulating structure while still allowing the frame to be fastened to the load-bearing structure of the wall structure.
  • all metals such as aluminium and steel, have a high thermal conductivity and thus any use of metal within the insulating structure of a wall structure will establish a thermal bridge between the warm environment within the building structure and the cold environment outside the building structure.
  • An advantage according to the present invention is that the absorbance of moisture by the element is avoided.
  • said profiled element is made of fibre reinforced composite material.
  • Fibre reinforced composite material includes a mixture of polymeric material and high strength fibres. In this way the structural strength of the profiled element may be increased compared to using polymeric materials only.
  • the profiled element preferably has a shape resembling an I-beam.
  • the profiled element is capable of supporting a frame.
  • the frame is typically a rectangular structure capable of supporting its own weight and the weight of a panel or window pane enclosed within the frame.
  • the frame is located within an opening of a wall structure. The opening extends completely through the wall structure.
  • the wall structure comprises the load-bearing structure and the insulating structure.
  • the inwardly facing surface of the wall structure is intended to face the interior of the building. Since the interior of the building is typically heated, the inner wall of the load-bearing structure faces a warm environment.
  • the outwardly facing surface of the load-bearing structure faces the inner surface of the insulating structure and is thus also located within the warm environment. Thus no temperature gradient exists between the inwardly facing surface and the outwardly facing surface of the load-bearing structure.
  • a small spacing in-between the outwardly facing surface of the load-bearing structure and the inner surface of the insulating structure may exist for allowing ventilation.
  • a temperature gradient is present in the transverse direction between the inner surface and the outer surface of the insulating structure.
  • the inner surface of the insulating structure thereby defines the boundary of the warm environment, and the outer surface of the insulating structure thereby defines the boundary of the cold environment.
  • the profiled element is made of fibre reinforced composite material which is substantially rigid and which is capable of supporting the total weight of the frame including any panels or window panes.
  • polymeric materials instead of metals, no thermal bridge is created between the inner surface and the outer surface of the insulating structure.
  • Polymeric materials have a significantly lower thermal conductivity than metal.
  • polymeric materials have, in contrast to wood, the advantage that that they do not absorb any moisture. The absorbance of moisture into a wooden element will weaken the element and result in an increased risk of material degradation caused by decomposition and fungi. Further, the more insulation that is used in the insulating structure, the greater is the risk of moisture formation. Further, the moisture within the wooden element may contaminate the insulation structure.
  • the profiled element comprises a first flange which is firmly mounted onto the outwardly facing surface of the load-bearing structure.
  • the first flange may be fixed by e.g. bolts or screws to the load-bearing structure.
  • the interconnecting member is connected to the first flange and extends in a direction away from the first flange and the outwardly facing surface.
  • the interconnecting member is dimensioned to extend into the insulating structure to a position in-between the inner surface and the outer surface of the insulating structure.
  • the interconnecting member is thus intended to be concealed within the insulating structure so that it is at least partially invisible when the insulating structure covers the load-bearing structure and cannot be accessed at the opening without removing the insulating structure.
  • the second flange is connected to the interconnecting member at a location opposite the first flange, i.e. the first flange and the second flange are not directly connected.
  • the second flange defines the support area which is indented to hold the frame.
  • the frame may be loosely positioned on the support area or alternatively fixed by bolts, screws etc.
  • the profiled element is dimensioned so that the support area is located between the inner surface and the outer surface of the insulating structure.
  • the second flange is exposed relative to the insulating structure meaning that the support area is visible and accessible at the opening when the insulating structure covers the load-bearing structure.
  • the first flange, interconnecting member and second flange are typically manufactured in one piece.
  • the support area is thus capable of holding the frame at a position adjacent the insulating structure and thus no thermal bridge will exist through the wall structure between the interior environment of the building and the outside of the building.
  • insulation is construed to mean thermal insulation.
  • the above element primarily concerns the prevention of a thermal bridge between a warm environment inside a building structure and a cold environment outside the building structure, it is contemplated that the same element may be used between a cold environment inside a building structure and a warm environment outside a building structure, e.g. in a temperature controlled building in a country having tropical heat.
  • said interconnecting member and/or second flange is partially hollow or foam-filled for reducing the thermal conductivity of the second flange.
  • polymeric materials typically have a very low thermal conductivity, the thermal conductivity may be even further reduced by making the interconnecting member and/or second flange partially hollow or foam-filled.
  • the foam may be generated either by foaming of the polymeric material itself, e.g. by including a foam generator when producing the profiled element, or a piece of foam or hollow material may be included in the polymeric material.
  • the hollow or foam-filled portions of the interconnecting member are preferably located in the core of the interconnecting member.
  • said profiled element is manufactured by using the pultrusion technology.
  • pultrusion technology high strength fibre reinforced composite elements may be produced in a simple and efficient way.
  • Pultrusion is a technique in which a fibre bundle is pulled through a die together with polymeric material preferably in the form of a curable resin.
  • said fibre reinforced composite material includes impregnation material being either polyurethane (PUR), polyisocyanurat (PIR) or epoxy.
  • impregnation material being either polyurethane (PUR), polyisocyanurat (PIR) or epoxy.
  • PUR polyurethane
  • PIR polyisocyanurat
  • epoxy epoxy
  • said fibre reinforced composite material includes reinforced fibres being either glass fibres, aramid fibres, natural fibres or thermoplastic fibres.
  • reinforced fibres being either glass fibres, aramid fibres, natural fibres or thermoplastic fibres.
  • high strength reinforcing fibres which may be used to increase the structural strength of the profiled element.
  • said reinforced fibres are provided in the form of a woven or non-woven web.
  • the web structure is preferably oriented in a direction which substantially coincides with the force which the profiled element is to be supporting between the support surface and the outwardly facing surface of the load-bearing structure.
  • said structural element defines an overall heat transfer coefficient U between said second flange and said first flange of no more than 0.5 W ⁇ m -2 ⁇ K -1 , preferably no more than 0.25 W ⁇ m -2 ⁇ K -1 , more preferably no more than 0.15 W ⁇ m -2 ⁇ K -1 , most preferably no more than 0.10 W ⁇ m -2 ⁇ K -1 .
  • the above are typical preferred values of the thermal conductivity of the profiled element for avoiding any thermal bridge and when using suitable polymeric materials.
  • said interconnecting member has a tapered configuration from said first flange towards said second flange.
  • a tapered configuration of the interconnecting member is preferred in order to translate the vertical load force from the frame onto the load-bearing structure which is positioned at a horizontally translated position relative to the frame. Further, the tapered configuration reduces the torque force onto the load-bearing structure. Yet further, the tapered configuration reduces the total amount of materials needed for the interconnecting member.
  • said specific distance between said first flange and said support area of said second flange is between 10mm and 1000mm, preferably between 50mm and 500mm, more preferably between 100mm and 200mm or 200mm and 300mm such as about 160 mm or about 240 mm.
  • the above values correspond to the typical thickness of the insulation structure used in modern buildings.
  • the building structure according to the third aspect of the present invention may be constructed by using the method according to the second aspect of the present invention together with the profiled element according to the first aspect of the present invention.
  • the building structure may be any building which is intended for human habitation.
  • said frame being a window frame or a door frame, said frame preferably including a glazing sheet or a panel.
  • the panel/glazing sheets are preferably insulated. More preferably, multiple panels and/or glazing sheets are used with insulating material/vacuum in-between each of the panels/sheets.
  • said frame defines a top edge, a bottom edge and two oppositely located side edges, and wherein said support surface of said second flange is supporting said frame at said bottom edge and/or at said top edge and/or at said side edges.
  • the frame is supported at the bottom edge onto which the gravity force is acting.
  • the frame may also be fastened at its side edges or top edge.
  • the side or top edges may also be held by significantly smaller and non-load-bearing brackets or supports, preferably made of polymeric material. Nevertheless, it is also feasible to support the frame at its side and/or top edges only using the profiled elements according to the present invention.
  • said first flange or said profiled element is mounted by bolts and/or screws onto the outer surface of the load-bearing structure. In this way the profiled element may be securely fastened onto the load-bearing structure.
