Definitions

  • the invention relates to a method for manufacturing a staircase and to a staircase thus manufactured.
  • EP 0 489 251 A1 shows a staircase consisting of components that can be attached to the wall and to each other by means of screws.
  • the plate material in most cases is formed by wood, such as, for example, pine, oak or yellow poplar.
  • the wood must have a special hardness to ensure the staircase does not sustain damage during use.
  • Such kinds of wood are generally relatively costly.
  • US 2015/082716 A1 shows a precision built staircase kit for a staircase consisting of components made with a CNC machining station.
  • the plate material used can be, for example, plywood.
  • the known method moreover requires that the staircase, after placement thereof and after completion of the rougher construction activities, be painted or lacquered. This leads to a staircase being a relatively expensive object in a house. After a number of years, the staircase should be painted or lacquered again to keep it in a good condition. Maintenance of the known staircase is therefore relatively costly as well.
  • the invention envisages a method with the aid of which the above-described problems are at least partly solved.
  • the invention envisages a method for manufacturing a staircase that does not need to be painted or lacquered after placement thereof. Further, the invention envisages a staircase that can already be installed at an early stage of construction of a house, office or like building, so that during the further construction activities the construction workers can reach the storey floors via a safe staircase instead of via a ladder.
  • the invention provides a method for manufacturing a staircase according to claim 1.
  • the method for manufacturing a staircase as described hereinabove in the background section is characterized according to the invention in that
  • a staircase is formed of which at least the visible and/or exposed surfaces are clad with HPL (for example, of the brand Resopal®) or ABS laminate.
  • HPL for example, of the brand Resopal®
  • ABS laminate a description of HPL is to be found in the European standard EN438 Part 3.
  • HPL is particularly hard and wear-resistant, the plate-shaped core of the plate material can be made from relatively soft material. A pinewood core, a plywood core or an MDF core suffices for that purpose.
  • the cost price of the staircase manufactured with the method according to the invention can remain relatively low.
  • the staircase does not need to be painted or lacquered, which also brings a saving of cost with it.
  • HPL is available in a large number of decorative finishes.
  • HPL can be supplied with a wood decoration, natural stone decoration, a concrete appearance, stainless steel appearance, copper appearance, or AL appearance which may or may not be brushed or glossy. Further, HPL can be supplied in any desired colour.
  • a staircase can be given a character all its own.
  • the risers could have, for example, a metal look while the top of the treads could have, for example, a wooden look.
  • the forward-facing faces of the treads may be clad with yet another decorated HPL. Possibly, the forward-facing faces of the treads could also be clad with a metal strip. It is even conceivable that a staircase with different colour shades is manufactured, so that, for example, its bottom is light blue, changing gradually, with each tread up, into dark blue or any other desired colour.
  • the staircase can already be installed at an early stage of construction because the chances of the staircase sustaining damage are minimal since HPL is particularly scratch-resistant.
  • the HPL and the ABS laminate may be clad with a protective film that can be simply removed upon completion of construction.
  • the top of the treads could be temporarily protected with the aid of hardboard that can be removed after completion of construction.
  • the invention also relates to a staircase obtained with the method according to the invention.
  • the invention concerns a method for manufacturing a staircase 10.
  • plate material 12 is provided.
  • An example of this plate material is shown in Figure 1 .
  • this plate material is formed by planing, ripping, sanding, sawing and/or gluing together a carrier material based on wood, such as, for example, wood, plywood or MDF, to form a plate-shaped core 12a having a defined thickness.
  • the plate-shaped core 12a is covered on two sides with HPL 12b, 12c.
  • HPL is described, for example, in the European standard EN438 Part 3.
  • HPL of a suitable quality is supplied, for example, under the brand name Resopal®.
  • staircase component boards are manufactured.
  • treads 14 and stringers can be manufactured that are ready for assembly.
  • the machined faces 18a of the stringers 18 that are exposed and/or visible after assembly of the staircase are covered with HPL or ABS laminate 20.
  • An example of a stringer 18 clad with HPL or ABS laminate is shown in side view in Figure 2 , in which the recesses 18b provided in the stringer 18, in which the tread ends are received upon assembly, are clearly visible. Then, the treads 14 can be assembled into the stringers 18 to form a staircase 10.
  • the exposed, machined faces 14a of the treads 14 may be covered with HPL or ABS laminate.
  • the exposed faces 14a of the treads 14 may be clad with HPL or ABS laminate having a decoration different from or the same as the top of the treads 14. It is also possible, in an alternative embodiment, that the exposed faces 14a of the treads 14 are clad with steel strips, from, for example, stainless steel, aluminium, copper or like material.
  • treads 14 may be machined to form recesses in an underside thereof for partially receiving risers 24 therein.
  • the method can also comprise providing a newel core from carrier material based on wood, such as, for example, wood, plywood and/or MDF.
  • the newel core may be covered with HPL (for example according to EN438 Part 3) or ABS laminate to form a newel 26.
  • the newel 26 can be machined with the aid of a CNC machining station to form recesses 28 intended for receiving tread ends therein.
  • the method may further comprise providing a cap and placing the cap over a bottom of the newel 26.
  • a cap 30 prevents the HPL or ABS laminate applied to the main sides of the newel core being pulled loose from the newel core when the staircase 10 is being shoved during placement.
  • a cap 30 may be provided and be placed over a top of the newel 26. Such a cap 30 screens off the newel core's upper end face, so that this, too, does not need to be painted and, moreover, water ingress into the end wood is prevented.
  • the method in an embodiment, can also comprise providing risers 24 from carrier material based on wood, such as, for example, wood, plywood or MDF.
  • the method is then characterized in that the risers 24 are covered at least on two sides with HPL or ABS laminate.
  • Such an embodiment provides a staircase whose risers 24 do not need to undergo any further treatment, either.
  • the risers too, are particularly durable and do not become worn bald, because HPL and/or ABS laminate are particularly scratch-resistant.
  • the height of the risers 24 is determined by the rise of the staircase 10.
  • the risers 24 can therefore be sawn to size at the upward-facing side thereof.
  • the front and rear sides of the risers 24 are clad with HPL and so is, in this embodiment, the exposed downward-facing face of the risers 24. In such an embodiment, therefore, there is not a single exposed or visible surface of the risers that is not covered with HPL or ABS laminate.
  • the plate material 12 from which the treads 14 are manufactured may be provided on at least one side with HPL 12c having an antiskid surface structure.
  • HPL 12c having an antiskid surface structure.
  • an antiskid surface structure augments the safety of the staircase because the chances of a user slipping are reduced.
  • the decoration of the HPL can also be maintained in the antiskid variant.
  • balustrade rails 34 from carrier material based on wood such as, for example, wood, plywood or MDF, may be provided, which are then covered with HPL or ABS laminate.
  • the balustrade rails 34 can be machined with the aid of a CNC machining station to form recesses for receiving balustrade balusters.
  • balustrade rails 34 do not need to be painted or lacquered after placement of the staircase anymore, either. Further, such balustrade rails 34 are practically maintenance-free and just need to be cleaned now and then.
  • the high scratch resistance makes for a durable, fine appearance of the balustrade rails 34.
  • the HPL and/or the ABS laminate that is used may be provided with a removable protective film layer. After completion of the construction activities, the protective film layer can be removed. The protective film layer keeps the exposed surfaces of the staircase dust-free. Possibly, the tops of the treads may be protected by temporarily fixing hardboard thereon that can be removed after termination of the construction activities. The forward-facing face of the tread 14 may be protected by a plastic U-profile that is slipped over the front side and that also clamps the hardboard then.
  • the invention also relates to a staircase 10 of which all parts visible after assembly are clad with HPL or ABS laminate.
  • an upward-facing side of the treads 14 may be clad with HPL 12c having an antiskid surface structure.
