Definitions

  • the present invention relates to sandwich panels and in particular to sandwich panels for use in building construction, for structures of various different types and shapes.
  • Sandwich panels are pre-fabricated elements consisting of a pair of metal sheet layers sandwiching an inner core of insulating, and sometimes structural, non-metal material.
  • This inner core can be made from any material and is, in some implementations, typically a mix of a polymer and another component, such as polyethylene mixed with mineral wool to reduce combustibility. They are cheap to manufacture and have generally good insulation properties, whilst exhibiting excellent compressive and flexural strength, making them ideal for facades, partitioning walls and ceilings in industrial and commercial buildings.
  • Sandwich panels are generally made to standard specifications and used only to provide structural support and insulation. There is scope for improving on existing sandwich panels and their various uses.
  • a sandwich panel comprising a first metal layer; a second metal layer orientated substantially parallel to the first metal layer; a non-metal layer sandwiched between the first metal layer and the second metal layer; and a plurality of openings extending through the non-metal layer in a longitudinal direction, substantially parallel to the planes of the first and second metal layers, wherein the plurality of openings of same, similar, or different geometric forms and shapes, are preferably each surrounded on all lateral sides by the non-metal layer.
  • the first and /or second metal layer(s) may be generally planar, although they may include undulations or non-planar features, such as channels, ridges, recesses or other features as may be included to fulfil their required function. They generally extend in a planar manner, to preferably form a structural outer layer to the sandwich panel.
  • the openings may be provided substantially evenly across a full width of the sandwich panel. However, the openings may be spaced apart by different distances from one another. For example, the openings may be grouped together in sub-groups. Openings within a sub-group may be spaced apart by a first set of distances, which may be equal and which may be less than a first distance. Plural sub-groups of openings may be provided. The sub-groups may be spaced apart by a second distance, which is greater than or equal to the first distance.
  • the metal layers are preferably made from a metallic material, but in some embodiments can be made from a non-metal material, but preferably having stronger mechanical properties than the core material of the non-metal layer.
  • the core material is primarily insulative, but combines with the outer layers for improved structural strength.
  • the metal layers are preferably metallic, but may be made of any material and are generally intended to provide structural strength to the non-metal or central layer 106, 206, 306, 406, 506.
  • the first and second metal layers may sandwich respective first and second principal faces of the non-metal layer.
  • the plurality of openings may extend from one lateral side of the non-metal layer to another lateral side of the non-metal layer.
  • the plurality of openings may be positioned substantially equidistant from the first and second principal faces of the non-metal layer.
  • the non-metal layer may comprise a polymer and/or a mineral material and/or polyisocyanurate.
  • the first and/or second metal layers may comprise aluminium or steel.
  • One or more of the plurality of openings may be polygonal in cross-section or have a closed-curve cross-section, which means that the outer profile of the cross-section is formed from a curve which makes a closed loop and may have any curved profile. Circles and ovals are included as closed curves.
  • the closed curve may include one or more straight sides.
  • One or more of the plurality of openings may be triangular in cross-section.
  • One or more of the plurality of openings may be square or rectangular in cross-section.
  • One or more of the plurality of openings may be hexagonal in cross-section.
  • One or more of the plurality of openings may be circular or oval in cross-section.
  • Two or more adjacent openings of the plurality of openings may have a triangular cross-section, the orientation of which alternates by 180 degrees from one opening to the next.
  • the sandwich panel may have an overall thickness between outer surfaces of the first and second planar metal layers of around 4 to 25 centimetres, preferably around 10 to 12 centimetres.
  • One or more of the first and second metal layers may each have a thickness of between 0.5 and 1 millimetre.
  • the sandwich panel may have a length of 10 to 14 metres, or 12 metres, but this typically depends upon the size of a building to which the panel will be applied.
  • the ratio between the length and the thickness of the sandwich panel may be between 100:1 and 120:1.
  • the ratio between the thickness of the sandwich panel and the thickness of the first metal layer and/or the second metal layer may be between 100:1 and 240:1.
  • a ratio of the overall volume of the non-metal layer to the volume of the plurality of openings may be between 1:0.2 and 1:0.4.
  • the ratio of the overall volume of the non-metal layer to the volume of the plurality of openings may be between 1:0.25 and 1:0.35. Other ratios are possible.
  • a structure comprising a plurality of sandwich panels according to the invention.
  • a gas or water pipe or an electricity cable may be provided in one or more openings in the plurality of sandwich panels.
  • One or more openings in the plurality of sandwich panels may contain a data cable.
  • the data cable may be an electrical cable or an optical cable.
  • a longitudinal plane of one or more of the plurality of panels may be in a substantially horizontal orientation or in a substantially vertical orientation.
  • a longitudinal plane of one or more of the plurality of panels may be orientated substantially between 0 and 45 degrees from the vertical or substantially between 0 and 45 degrees from the horizontal.
  • One or more of the plurality of panels may form part of a roof of the structure.
  • a building may be provided comprising a structure comprising panels of the invention.
  • the building or structure may comprise at least one panel, an opening extending through the principal face of the panel being configured to communicate fluid into and/or out of a room around which the panel or panels is/are arranged, via one or more of the openings extending through the panel.
  • the building or structure may comprise a non-horizontally oriented panel, having a plurality of non-horizontally-oriented openings therein, the openings being open to surrounding air at an upper end and at a lower end, such that heat applied to an outer surface of the panel causes heated air in the openings to circulate to remove heat from the panel. This is preferably due to convection effects or "chimney" effects.
  • Embodiments of the present invention provide for a novel sandwich panel design which has been found by the inventors to reduce panel mass.
  • the inventors have realised that by adding elongate openings, cavities, or conduits, within the sandwiched non-metal material of a sandwich panel, the overall weight of the panel can be reduced due to the removed material, while other properties of the panel, such as for example thermal insulation properties, are not adversely affected, and may even be improved.
  • New implementations for a panel have also been identified, which provide improved utility.
  • Figures 1a, 1b and 1c graphically illustrate a sandwich panel according to an embodiment of the present invention.
  • the panel 100 comprises a first planar metal layer 102 and a second planar metal layer 104 orientated substantially parallel to the first metal layer 102.
  • Sandwiched between the first and second metal layers 102, 104 is a non-metal layer 106.
  • the metal layers 102, 104 are typically made from lightweight sheet metal such as aluminium or steel or any alloy thereof.
  • the metal layers 102, 104 may be coated on their outside surface for aesthetic benefit using any form of decorative material, such as paints or coatings, for example, polyvinylidene fluoride (PVDF), fluoropolymer resins (FEVE) or polyester paint.
  • PVDF polyvinylidene fluoride
  • FEVE fluoropolymer resins
  • polyester paint any form of decorative material
  • the non-metal layer 106 is typically made from a polymer, such as polyethylene, although a popular core material for the non-metal layer 106 is polyisocyanurate, and panels using this material in their non-metal layers are available from producers such as KingspanTM.
  • sandwich panels used in the building industry although they are not limited to such uses, and in particular tho se used for commercial and industrial use, have a thickness of between 4 centimetres and up to around 25 centimetres, and in some examples, between around 10 centimetres and 12 centimetres, measured between the outer surfaces of the first and second metal layers 102, 104 respectively. In some circumstances, the sandwich panel may be up to around 20 centimetres thick.
  • the thickness of the first and/or second metal layer 102, 104 is conventionally between around 0.5 and 1 millimetre, but is not limited to these values and may be thinner or thicker in certain applications, depending upon design and loading criteria.
  • the sandwich panel 100 can have, for example, an overall thickness of between 8 and 14 centimetres. In other examples, the sandwich panel has a thickness of around 10 to 12 centimetres.
  • the first and/or second metal layers 102, 104 may have a thickness of anywhere between around 0.2 and 2 millimetres and preferably between 0.5 and 1 millimetre.
  • sandwich panels typically have a width (w) of around 1 - 1.2m and a length (1) of between 10 and 14 m and in some embodiments a length and width of 12 m, i.e. a 12 m x 12 m square is possible.
  • a plurality of openings, cavities, or voids 108 are provided within the non-metal layer 106. These openings preferably extend through the non-metal layer 106 in a longitudinal direction, substantially parallel to the planes of the first and second metal layers 102, 104.
  • the openings 108 are preferably surrounded on all lateral sides by the non-metal layer 106. In other words, in preferred arrangements, no part of the conduits 108 opens onto the metal layers 102, 104; the conduits 108 are therefore preferably formed completely within the non-metal layer 106, opening only at the edges of the panel 100.
  • one or more of the plurality of openings 108 extend completely through the length of the non-metal layer from one edge to the other. In other embodiments, however, the openings may extend only partially through the non-metal layer 106. To this end, the openings 108 may form pockets within the non-metal layer or may terminate at one edge or the other of the non-metal layer 106.
  • Embodiments of the present invention may comprise any combination of closed and/or open openings formed in the non-metal layer, terminating at one or other or both sides or ends of the panel 100.
  • the openings run in a parallel orientation relative to one another from one edge to the other edge of the panel 100.
  • the openings may be orientated in a non-parallel fashion.
  • the conduits 108 may have one or more bends, whilst still extending generally laterally or longitudinally through the non-metal layer 106.
  • conduits may cross one another in different lateral directions through the panel 100 whilst all still extending in directions parallel to the primary plane of the panel 100.
  • the conduits have a triangular cross-section, in particular that of an equilateral triangle.
  • the conduits may have a cross-section of other triangles (isosceles or irregular, for example) or other polygonal or non-polygonal shapes. Examples include squares, circles, ovals, rectangles, pentagons, hexagons, to name a few. Circles may be preferred for ease of manufacture.
  • the conduits are provided with triangular cross-sections similar to those shown in Figures 1a and 1b , and more preferably equilateral triangles.
  • alternating orientations of triangular cross-section conduits rotated by 180° with respect to their neighbouring openings can be used.
  • the overall volume of material used, and the resulting, weight is also reduced, while other properties, such as thermal insulation, may be enhanced or maintained.
  • any or all of the openings 108 may be provided with a liner or insert 111.
  • This liner or insert can have a number of functions.
  • a first function is where pipes or cables are to be placed in the openings.
  • inserts of liners can protect the non-metal layer from wear and tear or damage in use or during the insertion process.
  • the inserts or liners may be fire retardant or fire resistant and so, in the event of a fire, such as a gas or electrical fire, due to the pipes or cables being located in the openings, the liners or inserts can reduce or prevent damage to the panel 100.
  • the insert may be a pipe suitable for carrying fluids such as gas or liquids, in isolation from the non-metal layer, and so it can form an integral pipe for carrying fluids through the panel.
  • the following calculations provide quantitative examples of the reduction in volume of a non-metal layer, and therefore its weight, when various openings or different shapes and sizes are formed therein. For simplicity of calculation and for illustrative purposes only, these calculations assume that the non-metal layer 106 of the sandwich panel 100 is, for example, 10 centimetres thick from its first principal face 110 to its second principal face 112. As mentioned above, however, the non-metal layer 106 may have a different thickness in other embodiments.

  • FIG. 2b a side view of a sandwich panel 300 according to a further embodiment of the present invention is shown comprising a plurality of square openings 116 disposed within the non-metal layer 106.
  • the non-metal layer 106 is again considered to have a thickness from its first principal face to its second principal face of T and the cross-section of the square openings S 2 , the gap between the edges of each of the adjacent openings 116 being s .
  • N openings can be provided in a selected section of sandwich panel 300.
  • the skilled reader will be able to calculate the volume of other forms of opening by multiplication of the cross-section area by the overall length of the opening, and can find the ratio of volume of material removed to the total volume of the non-metal layer in the absence of the openings, as shown above.
  • a possible ratio of overall volume of the non-metal layer to the volume of the plurality of openings provided therein is between 1:0.1 and 1:0.5 and more preferably between 1:0.2 and 1:0.4. Further, even more preferably the ratio of the overall volume of the non-metal layer to the volume of the plurality of openings is between 1:0.25 and 1:0.35. Other ratios can be advantageous for certain implementations.
  • panels use less material for the non-metal layer 106, thus reducing the use of materials and especially, hydrocarbon-based materials such as the polymer, which may be any type of polyethylene.
  • hydrocarbon-based materials such as the polymer, which may be any type of polyethylene.
  • these openings can be used to carry gas or water pipes or electricity cables as well as other cables such as data cables for electrical or optical data transfer.
  • the openings can also be used to carry fluids for ventilation, heat transfer or humidity control.
  • the cross-section of openings provided within the non-metal layer 106 of the material need not necessarily be all the same shape and size and can be of different shapes and sizes. Further, the openings need not necessarily be located at a centre point through the thickness of the panel either, one or more of the openings may be located toward a first metallic layer or a second metallic layer of the panel. The openings may not necessarily be of constant cross-section along their length and could have a varying, increasing or decreasing cross-section along their length.
  • Figures 2c and 2d provide just two of many examples of sandwich panels falling within the scope of the present invention comprising openings having different shapes and sizes.
  • any combination of size and/or shape of openings in any possible configuration may be provided within the non-metal layer 106, and the extent to which each of these openings extends through the length or width of the non-metal layer 106 may vary in any manner from opening to opening.
  • one or more of the plurality of openings may extend all the way through and others may not; one or more of the plurality of openings may be completely encapsulated within the non-metal layer, and others may not; one or more of the plurality of openings may run in a different direction through the non-metal layer to others of the plurality of openings.
  • all of the openings extend through the non-metal layer in a longitudinal direction substantially parallel to the plane of the first and second planar metal layers.
  • each of the plurality of openings may be positioned substantially equidistant from the first and second principal faces of the non-metal layer.
  • each of the plurality of openings running through the non-metal layer may be at different relative distances from the first and/or second in a direction parallel to the plane of the first and second planar metal layers but preferably not in a direction perpendicular to the plane of the first and/or second metal layers.
  • Figure 3 shows an alternative arrangement in which the openings are located in closer proximity to a first metallic layer 302 than to a second metallic layer 304.
  • This configuration can be useful for certain arrangements in a structure.
  • heat transfer fluid such as gas, air or liquid
  • heat delivered to layer 304 can be removed from the panel by the flow of fluid through openings 308.
  • the heat removed from the panel can be dissipated to the atmosphere at another location, for example by routing it to another channel which is simply out of direct sunlight, in a shaded area, or alternatively, a heat engine, such as a powered refrigeration unit could be used to remove heat from the fluid once the heat is removed from the panel.
  • a heat engine such as a powered refrigeration unit could be used to remove heat from the fluid once the heat is removed from the panel.
  • This arrangement can therefore remove heat from the panel and reduce the amount of heat energy reaching the cooler side 302 of the panel.
  • This can effectively increase the insulating effect of the panel and is particularly useful in cold rooms or cold stores, for example, since in such instances, it is particularly advantageous to remove heat from the panel before it has a chance to reach the internal side of the panel when it provides a wall or ceiling for a cold store or cold room or other space to be kept at a set temperature.
  • the openings can therefore act as conduits for a heat transfer fluid for the removal of heat from the panel.
  • the conduits are advantageously placed in a path of heat transfer from a heated side to a cooler side of the panel.
  • the conduits may advantageously be located closer to the heated side of the panel than to the cooled side of the panel, although they can in some implementations be located nearer to the cooled side of the panel. If the conduits are oriented vertically, or in any non-horizontal configuration, then a 'chimney effect' can be created, in which heat applied to the panel heats the heat transfer fluid. This causes the heated fluid to be less dense and so causes the fluid to rise, pushed upwards by heavier, denser fluid acting at a bottom or lower end of the conduit. This can occur because the heat transfer fluid in another part of the conduit, or fluid outside of the conduit, or fluid in a part of a circuit to which the conduit is connected is denser and so heavier, which causes the lighter heated fluid to rise.
  • Figure 4 shows a further alternative arrangement in which one or more of openings 408 is/are provided with vents passing through outer layer 402. This is to permit a fluid such as air to be delivered through the openings 408, to a space adjacent layer 402. This can be useful for delivering a fluid, such as air, to a room around which one or more of the panels is installed, for example.
  • Other fluids could be delivered through the openings 409, to generally heat, cool control humidity, to generally air-condition, or to control any aspect of the atmosphere in the room. Fluid can, or course, also be aspirated through the openings 409 if desired, to extract air, smoke, or generally to extract fluid from the room around which the panel or panels are assembled.
  • Figure 5 shows an arrangement which combines the functionality of Figures 3 and 4 . Therefore, the panel 500 may comprise a first set of one or more openings or conduits 508 located toward a first side of the panel and a second set of one or more openings or conduits 511 located toward a second side of the panel.
  • the first set of openings or conduits may comprise openings 509 through a side of the panel as described in respect of Figure 4 .
  • the second set of conduits or openings may be used as described in relation to Figure 3 .
