Definitions

  • the present invention relates to an elongate retaining element for building sheets e.g. for a roof or façade, comprising an elongate engagement section with a head section at one end of said engagement section for engaging at least one building sheet, by flanging a free end of said building sheet over said head section, and an elongate base section for mounting the elongate retaining element on a support structure wherein the direction of elongation of the engagement section, base section and of the retaining element are the same.
  • the present invention further relates to an assembly of at least one such elongate retaining element and at least one building sheet mounted thereby on a support structure and also to a connection section forming part of such an elongate retaining element.
  • the known elongate retaining element comprises an elongate extruded aluminium "upside-down-T"-shaped profile. As seen in cross section perpendicular to its direction of elongation, the cross bar of the "upside-down-T"-shaped profile forms the base section, which is provided with drilled holes for connecting elements such as screws passed through the drilled holes to connect the elongate retaining element to a supporting structure of a building, such as for example supporting beams, T-bearers or similar structural elements manufactured from for example wood, steel, aluminium or concrete.
  • An elongate engagement section extends perpendicularly from the elongate base section and comprises at its end a wider head section that in this specific example is substantially triangularly shaped in cross section.
  • the direction of elongation of the engagement and base sections is the same as the direction of elongation of the retaining element.
  • the free ends of the building sheets are flanged over the head section such as to allow for a longitudinal sliding movement of the building elements relative to the elongate retaining element.
  • the known elongate retaining elements can be an "upside-down" T-shape, asymmetrically shaped, or it can even be an L-shape.
  • the known retaining element is formed wholly from metal, namely aluminium. Metal is a good heat conductor.
  • Metal is a good heat conductor.
  • a colder outer temperature and a warmer inner temperature leads to the possible formation of condensation on the interior of the supporting structure as well as heat loss from the interior of the supporting structure. This occurs because the head section of the retaining element is in direct contact with the metal building sheets that are exterior to the support structure.
  • the retaining element as a result cools and also cools the air surrounding it, which reduces the amount of water the air can hold and condensation can form.
  • the condensation formation can lead to multiple problems within the support structure e.g. rotting of organic structures, corrosion of metallic structures.
  • the known retaining element acts as a thermal-bridge. It also conducts heat to the interior if the exterior temperature is warmer than that of the interior. This phenomenon can lead to higher energy costs for cooling the building by e.g. air-conditioning.
  • GB-A-2167101 discloses a retaining element according to the preamble of claim 1.
  • One or more of these objects is achieved by connecting the engagement section and the base section by means for reducing the thermal conduction between the engagement section and the base section where the means has a lower thermal conductivity than the engagement section and base section.
  • the means reduces the thermal flow in the retaining element when the exterior of the support structure is at a lower temperature than the interior as it has a lower thermal conductivity than the engagement and base sections.
  • the parts of the retaining element below the means are thus at least partially insulated from the potentially cooler exterior temperatures and the problematic formation of condensation is reduced.
  • the heat loss through the retaining element is also reduced.
  • the means preferably comprise a connection section positioned in contact with the base section and engagement section and which separates the engagement section from the base section i.e. ensures they are not in direct contact with each other.
  • the base section of the retaining element which is mounted on the support structure, is thus at least partially insulated from the potentially cooler exterior temperatures.
  • connection section preferably interlocks with said base section and/or said engagement section.
  • the retaining element does not require chemical bonding methods to ensure stability as the base section and/or engagement section engage mechanically with the connection section by overlapping or by the fitting together of projections and recesses.
  • This structure has the advantage of improved mechanical stability as it reduces the likelihood of disengagement of the thermally insulating connection section from the engagement or base section.
  • the retaining element requires considerable mechanical stability, as it needs to be able to withstand the loads exerted by the weight of the building sheets as well as any uplift caused by the wind acting on the building sheets.
  • the base and/or engagement section preferably comprise at least one groove for receiving part of the connection section.
  • the connection section thus extends at least partially into the base and/or engagement section and is compressed between the base and engagement section thereby reducing the likelihood of disengagement.
  • At least one of the grooves is of substantially circular or truncated circular cross-section where the cross section is perpendicular to the direction of elongation of the retaining element.
  • the connection section is thus firmly retained within the engagement and/or base section thereby further optimising mechanical stability.
  • At least one of the grooves varies in cross-sectional width as it extends into the engagement and/or base section, where the cross section is perpendicular to the direction of elongation of the retaining element.
  • the connection section is thus firmly retained within the engagement and/or base section thereby further optimising mechanical stability.
  • the base section and engagement section preferably comprise at least two grooves each for receiving at least part of the connection section the mechanical stability of the retaining element is enhanced and the load diffusion between the engagement and base sections is improved.
  • This improved load diffusion is particularly advantageous if the retaining element is used on a support structure exposed to snow fall as the retaining elements will need to be able to bear the load of the building sheets and a snow layer.
  • the engagement and base sections are preferably metallic. When used on a structure in which the building sheets are exposed to the elements the retaining elements need to be able to withstand temperatures ranging from sub-zero to 70°C and above. Metals such as aluminium, steel or aluminium alloys are strong and can easily withstand the temperatures at the higher and lower ends of the scale as well as the temperature changes that will occur without their strength or stability being compromised to any significant extent.
  • the present invention is particularly advantageous when the engagement and base sections are made from metal, as the high thermal conductivity of metals would otherwise lead to the occurrence of thermal-bridges.
  • connection section is preferably made from a material with a thermal conductivity of less than 15 Watts/mK, preferably less than 10 Watts/mK or preferably less than 5 Watts/mK.
  • the relatively low thermal conductivity of the material optimises the insulating effect of the connection section.
  • the connection section may be made from a resilient plastic material.
  • the resilience of the material has the advantage that there is less likelihood of failure when the elongate retaining element is subjected to dynamic and static transverse loads.
  • Plastics are also materials with low thermal conductivity.
  • the resilient plastic material can be for example polyamide, polyester, polyethylene, polyurethane, cellulose or modifications of any of these polymers. This list is not exhaustive and is non-limitative.
  • the strength of the connection section is increased by using reinforced resilient plastic material.
  • the resilient plastic material can be reinforced with, for example metal or glass, polyester, aramid or carbon fibres.
  • Fig. 1 shows in cross-section a retaining element 1 in accordance with the present invention comprising an engagement section 22 made up of a head section 2 and an extended section 5, a base section 4 and means 36 connecting the base and engagement section in the form of a connection section 6.
  • the means 36 may be positioned at any point between head section 2 and base section 4.
  • the base section 4 is provided with holes 9 for fixing means for joining it to a support structure, for example, of a building.
