Definitions

  • the present invention relates to a method for manufacturing a wall panel which contains a frame opening.
  • the present invention aims to improve the known method.
  • the present invention provides a method according to the preamble, wherein an intrados profile is used which defines a frame opening and the intrados profile is provided with an anchoring member at its outer circumferential side, the anchoring member of the intrados profile is embedded in mortar, and the mortar is set to yield a wall panel in which the intrados profile is integrated wherein either
  • a suitable thickness of the strip depends on the resilient properties of the mineral wool used. In general, a thickness of at least 2 cm, preferably at least 3 cm is suitable.
  • the strip is applied in the form of segments (1 for each side of the casing comprising an intrados profile).
  • the strip is for instance glued to the casing or secured using nails. Any gaps between adjacent segments will automatically be pushed closed as a result of contact with the second layer.
  • the method according to the invention makes it possible to have a frame protrude beyond the front side, without the need of making (a great deal of) adjustments. Nevertheless, a more conventional arrangement of the frame is also possible, or a frame situated at the backside of the wall panel.
  • a wall panel manufactured using the method according to the invention requires less finishing, since the frame opening is already provided with an intrados profile.
  • an intrados a shielding for an opening of a panel is meant which hides the interior of the panel at least partially from view, insofar that interior is not already hidden partially from view by a frame.
  • a rectangular opening there are usually 4 intrados, or, when a frame connects intrados at the inside and the outside of the panel with each other, 8 intrados.
  • a lowermost intrados (after putting the panel upright) may take the form of a windowsill, and in this way further finishing thereof can be avoided.
  • An intrados can also serve for simplifying further finishing.
  • intrados profile means an element constituted from one or more intrados that can function as a casing and, optionally in cooperation with a frame and a second intrados profile, can hide the centre of a wall panel from view.
  • an intrados profile will have a rectangular shape, but others forms, such as a circular shape, are conceivable as well.
  • a rectangular shape can be achieved in a simple way by connecting four separate intrados, which are for instance made of wood.
  • such an intrados profile may also be formed in one piece, for instance from plastic such as PVC.
  • the frame may be a frame for a window or a door.
  • An intrados usually has a thickness of 0.5 to 5 cm and preferably 1-3 cm, although thicker or thinner is also possible.
  • the intrados will usually have a thickness which is at least 3 times smaller than its width (wherein with width a dimension is meant measured in the direction of the front side towards the backside of the wall panel).
  • the anchoring member will usually be situated at a distance of between 0.5 cm and 5 cm from the front side of the wall panel.
  • the anchoring member is a strip that runs along the outer circumference of the intrados profile.
  • Such a strip has a width (the distance over which the strip of the intrados profile extends) of for instance at least 5 mm, preferably at least 1 cm and more preferably at least 2 cm.
  • a width the distance over which the strip of the intrados profile extends
  • any circumference of an intrados is meant on which an anchoring member that can be anchored in the mortar can be situated, thus including a side circumference.
  • the strip is for instance a metal, plastic or wooden strip.
  • the strip may be coarsened, perforated or be provided with a profile in order to ensure a proper adherence to the mortar.
  • the strip is preferably applied as a strip that runs along the circumference of the intrados profile. This also applies in the case where a frame or frame construction is provided with such a strip as an anchoring member.
  • the intrados profile forms part of the frame construction, and the frame construction is integrated with the wall panel by embedding and setting.
  • the term "forms part of" means that the intrados profile can be an intrados that is connected in a detachable fashion with the frame construction, it can be an intrados that is irremovably connected with the frame construction, or the intrados profile forms part of the frame construction and forms a totality therewith. If there is more than one intrados profile, this applies to the intrados profiles independently of each other. Thus, for instance, the first intrados profile can be connected in a detachable fashion with the frame construction, whereas the second intrados profile forms an integral part of the frame construction.
  • the frame construction forms part of a frame which comprises a window, and the frame comprising a window and the intrados profile is placed with the intrados profile onto the mould before the anchoring member of the intrados organ is embedded in mortar.
  • the intrados profile can be placed sealingly onto a casing element (dummy) in the form of a frame or plate, which is placed sealingly onto the mould, where the casing element preferably is of such little height that from the backside (i.e. the side which after application of the mortar onto the mould is turned away from the mould) at the most 2 cm of the set mortar of the front side of the wall panel is visible via the frame opening.
  • the term "sealingly" means that no openings are allowed that have such dimensions that mortar can flow from a location outside the intrados profile to a location situated within the intrados profile.
  • the maximally allowable size of the openings depends on the viscosity and thixotropic properties of the mortar or second mortar used, and will in general be less than 2 mm, such as less than 1.5 mm and for instance ca. 1 mm.
  • the intrados profile is placed sealingly onto the mould, in direct contact with the mould.
  • the foam material is an expanded polymer.
  • expanded polymer each type of polymer hard foam is meant, regardless of how it is formed.
  • the first and the second mortar can have identical or different compositions.
  • the second mortar is preferably a finishing mortar.
  • the method according to the present invention makes it possible to effectively and in a simple manner protect the expanded polymer against fire, and without affecting a proper integration of a frame construction in the wall panel, using a strip of fire-resistant material that is applied along the circumference of the frame which comprises a window, preferably prior to placing the frame comprising a window onto the mould.
  • the fire-resistant material is for instance glass wool or stone wool.
  • the invention also relates to an outer wall sandwich panel which comprises a first and a second layer of set mortar and a core layer of hard foam material, where the outer wall panel has a frame opening and is provided with intrados profiles having anchoring elements which are embedded in the first and the second layer of mortar respectively, wherein between the anchoring elements a strip of fire-resistant material is present selected from stone wool and glass wool.
  • the hard foam material is preferably expanded polymer as defined above.
  • Such a sandwich panel can be manufactured using the method according to the invention, can be placed very easily and requires little finishing. Any finishing at the construction site can be largely or entirely avoided.
  • the wall panel is highly suitable as an outer wall panel. Outer wall panels according to the invention usually have a width of at least 4 metres, preferably at least 5 metres and more preferably at least 6 metres.
  • a preferred embodiment is characterized in that both the first and the second intrados profile are part of the frame construction, and the frame construction is integrated with the wall panel by embedding and setting.
  • the frame construction is very firmly anchored in the outer wall panel.
  • the anchoring member is a strip which runs along the circumference of each intrados profile.
  • an outer wall panel which effectively and to a large extent avoids cold bridges and the penetration of moisture.
  • the strip has a width of for instance at least 5 mm, preferably at least 1 cm and more preferably at least 2 cm.
  • Fig. 1 shows a top plan view of a mould 1 on which upright walls 100 have been placed, on which mould 1 a wall panel according to the invention provided with a rectangular frame 2 comprising a window is formed.
  • Fig. 2a shows in a vertical cross section a detail of the mould 1 onto which the frame 2 comprising a window is placed sealingly.
  • the frame 2 comprising a window has a frame 3, double glazing 4 as well as a first intrados profile 5 and a second intrados profile 6.
  • the frame construction 3 and both intrados profiles 5, 6 are made of wood and interconnected by means of glue joints.
  • a dummy body A is provided which, either because of its weight or because it is connected with the mould 1, or forms part thereof, impedes displacement of the frame 2 or even makes it impossible.
  • the intrados profiles 5, 6 each have an anchoring strip 7 and 8, respectively which run along their outer circumference.
  • first mortar 9 is applied onto the mould 1, wherein the first anchoring strip 7 is embedded in the first mortar 9.
  • a plate of polystyrene 10 is placed onto the unset first mortar 9, after which a second mortar 11 is applied onto the polystyrene 10, wherein the second anchoring strip 8 is embedded in the second mortar 11.
  • the yet unset mortar 9, 11 is allowed to set to yield a largely finished outer wall panel in which the intrados 5, 6 are integrated.
  • more than 1 plate of expanded polymer 10 can be interconnected, for instance by glueing. This will usually take place after application of the expanded polymer onto the first mortar 9, in order to avoid that air gets trapped under the expanded polymer 10.
  • an underpressure can be applied. This is, for instance, possible by covering the totality of the mould and panel with a PVC foil, and subjecting the space under the foil to an underpressure.
  • the presence of bubbles may not be desirable, especially the large bubbles are disadvantageous, and especially the large bubbles, should they even occur, can be removed properly with the underpressure technique described above.
  • the air can escape between adjacent plates of expanded polymer or via holes that have been provided in the plates for this purpose. These holes can be made, for instance, by using, optionally hot, needles.
  • Another advantageous method to prevent air from getting trapped under the expanded polymer in the method according to the invention is using strips of hard foam having a width of 50 cm or less, such as 40 cm or less.
  • strips of hard foam having a width of 50 cm or less, such as 40 cm or less.
  • plates are cut to strips and the strips are placed with a cut face (thus, transverse to the original surface of the plate) on the first mortar.
  • the term "sealingly” means that no openings are allowed that have such dimensions that first or second mortar can flow from a location outside the first intrados profile 5 to a location situated within the intrados profile 5.
  • the maximally allowable size of the openings depends on the viscosity and thixotropic properties of the first mortar 9 or second mortar 11 used, and will in general be less than 2 mm, such as less than 1.5 mm and for instance ca. 1 mm.
  • the mortars used in the present invention further are lowshrinkage, that is to say that during setting they present a shrinking or swelling of no more than 1%, preferably less than 0.5% and more preferably less than 0.2%.
  • An example of a suitable mortar is TM5203 (Tillman, Megchelen, The Netherlands), which is prepared according to the instructions of the manufacturer.
  • the outer wall panels according to the invention will preferably comprise reinforced set layers of mortar.
  • the reinforcement is for instance in the form of reinforcement mats, such as hot dip galvanized wire mesh Casanet (wire thickness 2.05 mm; maze 50 x 50 mm; Van Rooy en Co, Rotterdam, The Netherlands). This is pressed in the layer of mortar, which was subsequently levelled off.
  • the second mortar 11 is advantageously a self-levelling mortar, such as ABS 340 of Beamix (Eindhoven, The Netherlands). This mortar contains fibres which function as a reinforcement. In order to prevent drying out, the mortar 11 can be covered, for instance with PVC foil, during setting.
  • the frame 2 comprising a window has a fire-resistant strip 12 along its outer circumference, for instance of stone wool.
  • Rockwool having a thickness of 3 cm (soft or semi-hard pressing; Lapinus, Roermond, The Netherlands) is used.
  • EPS 150 SE polystyrene
  • EPS 150 SE thickness 200 mm, Unidek, Gemert, The Netherlands
  • the second intrados profile 6 preferably has an end 13 that is, as seen from the front side, tapered or rounded off, wherein that much second mortar 11 is applied onto the polystyrene 10 that the second mortar 11 at least reaches that tapered or rounded off end 13.
  • an aesthetic attractiveness is achieved, wherein the part of the second intrados profile 6, which as seen from the front side of the outer wall panel protrudes beyond the backside of the outer wall panel, is not perceived as being poorly finished, whereas the exact thickness of the layer of second mortar 11 is less critical.
  • the glass of the frame 2 comprising a window will be provided with a protective foil (not shown).
  • the intrados profile 5 can be an intrados profile 5 that is connected in a detachable fashion to the frame construction 3, it can be an intrados profile 5 that is irremovably connected to the frame construction 3, or the intrados profile 5 forms part from of the frame construction 3 and forms 1 totality therewith. If there is more than one intrados profile, this applies for the intrados profiles 5, 6 independently of each other. Thus, for instance, the first intrados profile 5 can be connected in a detachable fashion to the frame construction 3, whereas the second intrados profile 6 forms an integral part of the frame construction 3.
  • the frame construction 3 forms part of a frame 2 which comprises a window, and the frame 2 comprising a window which comprises at least the one intrados profile 5 is placed with the one intrados profile 5 onto the mould 1 before the anchoring member 7 is embedded in first mortar 9, which in practice will be removed after placement of the outer wall panel.
  • the intrados profiles 5, 6 and the frame construction 3 can be provided with such a protective foil. In this way, any splashes of mortar and other dirt can be readily removed.
  • profile mats such as for instance profile mat 2/70 PO available from Reckli (Herne, Germany)
  • Reckli Reckli
  • an outer wall panel can be manufactured wherein the front view side requires no finishing or only minimal finishing and yet still looks attractive.
  • a sufficient sealing has to be provided for, such as already set forth above.
