Definitions

  • the present invention relates to a framing member comprising two structural members and an insulating material lying against inside facing surface areas of the structural members.
  • framing members such as studs or rails, with an integrated thermal break are known in the art and allow achieving the prescribed values for the total thermal resistance R c even in thin constructions.
  • framing members with an integrated thermal break can be used in various construction applications, such as in walls, roofs, door frames, window frames, floors and other load bearing and non-load bearing elements where a framing member is used.
  • the present invention provides a solution to the problem by providing a framing member according to the preamble, wherein the framing member further comprises one or more reinforcing elements that are each in contact with the insulating material and the adjacent structural members.
  • the reinforcing elements comprise fibre elements, preferably fibre mats.
  • Fibres are a sawable material that allows for optimal processing of the framing members as it can be cut quickly into any desired dimensions using conventional wood processing tools.
  • a framing member according to the preamble of claim 1 is known from WO 99/61718 .
  • a fibre strip is installed in a groove in the wooden upper and lower constructional element.
  • WO 99/61718 is silent about suitable production methods of the known framing member, but any production method will involve making a groove in each constructional element and placing the fibre strips in the grooves.
  • the invention has for its purpose to provide a framing member that can be easily produced in a variety of dimensions depending on the application.
  • the framing member according to the invention is characterized in that each of the two structural members is composed of parts adhered together with the interposition of the fibre elements.
  • the framing member produced by the method according to the invention is easily recognizable by an adhesion surface extending through the entire structural elements.
  • the invention further relates to a method of producing such a framing member, comprising the steps of:
  • the method according to the invention further comprises step e) of: choosing a foam as the insulating material and applying the foam against the inside facing surface areas of the adhered structural members, thereby making the foam surround the fibre elements.
  • the material of the structural members is: wood, including finger jointed and/or laminated wood, structural composite lumber, such as laminated strand lumber (LSL), laminated veneer lumber (LVL) and micro laminated lumber, oriented strand board (OSB), plywood, pressed wood, laminated layered board, synthetic wood or hardboard.
  • structural composite lumber such as laminated strand lumber (LSL), laminated veneer lumber (LVL) and micro laminated lumber, oriented strand board (OSB), plywood, pressed wood, laminated layered board, synthetic wood or hardboard.
  • the insulating material is mineral wool, non-mineral wool, foam, cellulose material or combinations thereof.
  • Figures 1A and 1D show a first preferred embodiment 30 of a framing member according to the present invention.
  • Figure 1A shows framing member 30 in longitudinal cross section
  • figure 1D shows framing member 30 in transverse cross-section.
  • the cross sectional lines are C-C'.
  • Framing member 30 has a typical elongated shape like a beam. Framing member 30 is layered of non-homogeneous material. Framing member 30 comprises two substantially parallel structural members 31 and an insulating material 32 lying there in between. The structural members 31 provide the majority of the mechanical properties of the framing element. The insulating material 32 provides the insulation property to the framing element, serving as a thermal break between the two elongated structural elements.
  • Framing member 30 comprises reinforcing elements 33 that are in contact with both the structural members 31 and the insulating material 32 lying there in between.
  • Reinforcing elements 33 comprise fibre elements.
  • the fibre elements are arranged in mats.
  • Suitable fibre elements are of sawable materials and include synthetic fibres, such as aramid fibres.
  • sawable materials are materials that can be easily processed using conventional (wood) processing tools.
  • the framing member according to the invention can be produced based on the insight that at least each structural member is to be composed of parts that need to be arranged opposite to each other, whereby fibre elements, preferably arranged in mats, are placed against the opposing surfaces of the parts and the parts are adhered together.
  • framing member 30 can be produced starting from a standard framing member 20 comprising alternating layers of structural elements and an insulating material.
  • the standard framing member 20 is sawn into two parts along a plane extending through the structural members and the insulating material. This plane preferably lies in the centre and comprises line C-C' in figure 1B .
  • fibre elements 33 are placed against the sawing surfaces of the two parts 20A and 20B.
  • framing member 40 can be produced by a second method according to the invention, illustrated in figure 2A .
  • each structural member is composed of parts 41A, 41 B that are arranged opposite to each other and the fibre elements 33, preferably arranged in mats, are placed between the opposing surfaces of the parts and the parts are adhered together.
  • a foam 42 is chosen as the insulating material and applied against the inside facing surface areas of the adhered structural members, thereby making the foam surround the fibre elements and forming the core of the framing member.
  • Materials for structural members used in the invention can be selected from a variety of sources including materials used commonly in the art. Lumber may be obtained from timber. Timber cut and prepared into boards planks or other ready for market pieces. Specific to this application the pieces marketed for use framing and building during construction. As used in this application, both wood; engineered wood (combined particles, strands, or veneers with a glue, polymer, composite or similar bond); and other materials used for the purpose of building and framing in the way that cut timber is traditionally used for framing and building.
  • Insulation is a low energy transmission material used in construction or manufacturing to slow the transfer of heat, sound, or other energy through materials.
  • strong structural materials have a high capacity to transfer heat and other energies through walls, roofs, and floors and insulation is added to structure so the combined transfer of energy is reduced and the structure becomes more energy efficient, less noisy and otherwise more comfortable.
  • Rigid closed cell polyurethane, open cell polyurethane, ceramics, and urethane are examples of insulation that could be used for insulated lumber applications.
  • Mineral wool, non-mineral wool, and blown cellulose are examples of insulation that do not have structural value for use in insulated lumber.
