Definitions

  • the present disclosure relates to a construction panel for building, and especially to a fire resistant construction panel.
  • prefabricated construction panels are increasingly used in order to facilitate the building process.
  • the prefabricated construction panel may thus be fabricated in a controlled indoor area without the risk of adding moisture from the outside into the panels, ensuring that the quality of the panel is stable.
  • sandwich insulating panels for walls, for example, have previously been used in the construction of buildings.
  • a sandwich panel consists of two face sheets and a core layer arranged between the two face sheets.
  • the face sheets are made of a stable material in order to support the construction.
  • the function of the core layer is mainly to contribute insulating properties and to have a load-transmitting function between the two face sheets.
  • These sandwich panels can be prefabricated in a protected environment in order to avoid the entry of damp into the panel.
  • Sandwich panels are often designed with wooden face sheets, which may challenge the fire safety in the wall construction. Furthermore, wooden face sheets can give rise, for example, to mould and fungus damages etc. in the panel.
  • a way to solve this is by using a construction panel having face sheets and core layers resistive to mould, and containing a fire resistant material.
  • This type of panel may also be suitable in the construction of so called passive houses, which require an effective climate shield and moisture barrier.
  • prefabricated construction panels cannot be made in continuous sizes without having to join two or more panels in order to achieve large walls. These joints may weaken the construction as well as decrease the ability of the panel element of resisting fire due to gaps.
  • a way to solve this is to provide the fire resistant panel with a male/female tongue and groove arrangement in order to join two panels together.
  • this type of construction may not fulfill the high standard fire resistant classification to EI60, which is required for certain building types. It is also a complicated and time consuming procedure in the prefabrication stages since it is not possible to easily adapt to the size of the building on site.
  • a fire resistant construction panel system comprising at least a first and a second panel element, each panel element comprising a first face sheet and a second face sheet, adapted to lend stability to the construction panel, an insulating core layer arranged between the first and the second face sheet, wherein the first face sheet, the second face sheet, and the core layer together form a sandwich-type construction panel, and wherein at least one of the first and the second face sheet consists of a fireproof material.
  • the construction panel system further comprises at least one longitudinally extending connector element, adapted to fit into a groove in each panel element.
  • each panel element extends along a longitudinal direction and is formed by each first and second panel element comprising a recess, wherein the recess extends between the first and second face sheets along a rim of the core layer.
  • the connector element comprises a first panel sheet, a second panel sheet, and an insulating core layer arranged between the first and second panel sheet, wherein the first panel sheet, the second panel sheet, and the core layer together form a sandwich-type connector element, and the outer dimension of the connector element corresponds to the width of the groove between the face sheets of the panel elements.
  • first face sheet, the second face sheet, and the core layer may together form a sandwich-type construction panel, a construction panel which is stable yet relatively thin and has very good insulating capacity may thus be achieved.
  • the same insulating capacity with a wall made from traditional building methods may require a much thicker wall.
  • the surface elements of a construction panel, that is the face sheets, with fire resistant material the overall fire resistance of a wall may be improved.
  • a gap in the panel joint occur. This gap may give rise to a number of weaknesses in the structure, for instance strength, but also the gap may allow air, oxygen, moisture or other unwanted material to enter the structure and the building.
  • overlapping it is meant that between the edges of a first and a second panel element to be joined, a groove may be formed by removal of core material along the rim of the panel element.
  • the groove in between the panel elements houses the connector element which bridges the gap between the two panel elements.
  • the term "connector element” or “connector” is to be interpreted as means for joining (i.e. a joining means) at least two panel elements together.
  • the overlapping connector element may thus be arranged in the groove between each pair of the core layers to be joined.
  • the width of the panel sheet of the connector element equals the width of the connector element core layer and the longitudinal extension of the panel sheet of the connector element equals the longitudinal extension of the connector element core layer.
  • a planar surface around the circumference of the connector element is formed which may allow for a tight fitting towards the surfaces of the groove and thereby improve the fire resistance.
  • At least one of the first and the second face sheet may consist of magnesium oxide.
  • Magnesium oxide has fire resistant capabilities, which means that a face sheet that contains magnesium oxide may provide a fire resistant panel element. Since the face sheet may be the part of the element that is arranged towards the environment in a room or towards the outside, a fire resistant shield may be advantageous. It is possible that the face sheets may contain other fire resistant components or a mixture of several fire resistant components. Furthermore, a highly alkaline, yet inorganic material, such as magnesium oxide, can thus prevent the possible incipient growth of mould, for example, in the construction in the event of damp formation. This may be in contrast to a situation in which, for example, wood is used in the face sheets.
  • the panel sheet of the connector element may be made from magnesium oxide.
  • the connector element By making the panel sheet of the connector element from magnesium oxide, the connector element may be provided with fire resistant capabilities.
  • the fire resistant characteristics may be similar to that of the face sheet.
  • the panel sheet may be made from the same material as the face sheet.
  • the thickness of the panel sheet may be the same as the thickness of the face sheet. However, if required due to safety and/or stability or any other reason, the thickness may be different.
  • the connector element may be fixated in the groove by a fixating means.
  • the connector element may require fixating in the groove.
  • Fixating the connector element may be required in order to provide a stable joint, but also in order to seal any gaps that may carry oxygen from outside of the building which may serve as fuel to a fire.
  • the fixating means may be for instance a glue, foam, self adhesive tape or a paste or the like.
  • the fixating may also be achieved by a mechanical fit.
  • the fixating means may be fire resistant adhesive glue.
  • the core layer may consist of a plastics material, preferably a foamed plastics material.
  • a plastics material of this kind may have the advantage that it is not organic, and thus further prevents mould growth, for example, in the panel. Moreover, such a material may not be water-permeable, which may give less risk of damp damage and greater insulating capacity.
  • the core layer of the connector element may consist of a plastics material, preferably a foamed plastics material.
  • the panel elements may be prefabricated in a plant, prior to use of the panel element in the construction of a building.
  • prefabricated panel elements By using prefabricated panel elements, it may provide flexibility to the building procedure on site as well as the prefabrication process is done in a controlled process in a plant where moisture levels may be low.
  • a method for forming a wall using a fire resistant construction panel system comprising the steps of: providing a first and second panel element, each panel element comprising a first face sheet and a second face sheet, adapted to lend stability to the construction panel, an insulating core layer arranged between the first and the second face sheet, wherein the first face sheet, the second face sheet, and the core layer together form a sandwich-type construction panel, and wherein at least one of the first and the second face sheet consists of a fireproof material; providing a first longitudinal recess between the first and second face sheet of the first panel element along a rim of the core layer; providing a second longitudinal recess between the first and second face sheet of the second panel element along a rim of the core layer; arranging a first and second panel element such that a longitudinal groove is formed from the first and second recesses; providing a connector element of a fire resistant material in the groove, the connector element joining the first and second panel element together, the connector element comprising a first and second panel element, each panel element
  • the method may thus allow an existing panel element to be joined with another without the need of fastening elements such as nails or screws.
  • the steps may be done in any suitable order, depending on the type of manufacture.
  • the core layer and the face sheet may be joined, and that the recess is cut or milled out subsequently.
  • the recess may be cut out or milled before the face sheet is applied.
  • the core layer may be manufactured having dimensions smaller than the face sheet, thereby forming the recess when they are joined.
  • the step of arranging the connector element may be altered to suit the type of manufacture and may thus be performed in a number of ways.
  • the panel elements may be arranged next to each other, and subsequently the connector element is arranged in the groove simultaneously.
  • the connector element is arranged in one recess of a first panel element, and subsequently the second panel element is arranged next to the first panel element such that the connector element connects the first and second panel elements. The method allows to repeat any steps as required, and to perform the steps in any necessary order.
  • the method may further comprise the step of applying fixating means in the longitudinal groove on a first and a second core layer.
  • fixating means may be an adhesive, a self adhesive tape or glue which may be fire resistant. Applying fixating means is the most preferred embodiment, but depending on the alternative fixating, for instance a mechanical press fit, the step of applying fixating means may be optional.
