Definitions

  • the invention relates to a method for manufacturing a string of a staircase and to a method for manufacturing a staircase with at least one string manufactured with the method.
  • the invention further relates to a thus manufactured stair string and staircase.
  • staircases for buildings has heretofore been a process entailing traditional craftsmanship, at least when the staircase is one with non-standard dimensions.
  • the basic components of a staircase are the treads, the risers and the strings in which the treads are fixed by means of housings.
  • the stair strings in particular can take very complex spatial forms.
  • An example hereof is a staircase with a landing in which more or less straight parts of the strings are alternated with curve or wreath pieces.
  • Even greater freedom in the design of a staircase can result in still further complexity in the form of for instance spatially twisted stair strings.
  • Parts of stair strings with a complex form have heretofore been manufactured by releasing a part with the desired shape from a solid piece of wood using projections.
  • the wood used for this purpose preferably contains no knots or knurls and is straight-grained.
  • the techniques employed according to the prior art are: sawing, planing, cutting and so on.
  • a drawback of the existing method is that the manufacture of more complex workpieces is limited to only very skilled staircase builders.
  • the existing art is comparatively costly due to material consumption, and particularly the man-hours required.
  • the object of the present invention is to provide improved methods of manufacturing stair strings and staircases, with which very complex spatial forms can also be made in efficient manner. It is a further object to provide a stair string and a staircase which can be manufactured in any desired form at limited cost.
  • the invention provides for this purpose a method for manufacturing a string of a staircase, comprising the method steps of: a manufacturing a template for the stair string, which template forms a vertical projection onto a horizontal plane of the stair string in the situation of use; b manufacturing structural parts from a substantially form-retaining plate material, wherein the structural parts correspond with segments of the template in a manner such that successive structural parts form at least partly overlapping segments of the template, and c joining together the structural parts successively in stacked manner.
  • the production of a perpendicular projection onto a horizontal ground surface is relatively simple, for instance using a ground plan of a building in which a staircase must be placed. In the case of non-standard staircases this will generally result in an elongate template with at least one curve.
  • This template can be manufactured from for instance a plate material such as plywood.
  • a large number of structural parts are then manufactured from plate material which each form a segment of the template.
  • These structural parts will generally also have an elongate form, but are not as long as the template.
  • the structural parts are then fixed to each other in stacked manner such that a perpendicular projection of the assembly of structural parts then provides the form of the template.
  • the structural parts are mutually connected during the stacking. In order to realize a smooth upper and lower edge on the assembly of structural parts joined together in stacked manner, the edges are preferably finished during an additional method step.
  • the labour-intensive steps of manufacturing the structural parts and joining together these structural parts require little specific knowledge of the building of staircases.
  • the manufacture of a stair string with the described method thus becomes considerably less expensive than heretofore.
  • Another great advantage is the considerable freedom in the design of a stair string; all desired forms can be manufactured.
  • a further advantage is that the desired form can also be arranged accurately in the stair string; the form is controllable.
  • the method enables manufacture of the stair string from plate material (for instance multi-ply or MDF), which provides a considerable saving compared with the use of good-quality solid wood from which the stair string is generally released in parts.
  • step b so many structural parts are manufactured that the associated overlapping segments of the template enclose the whole template.
  • the stacking of structural parts is only possible when successive structural parts overlap each other over a considerable length. Only when this condition is satisfied can the structural parts be connected firmly to each other.
  • the structural parts because of the required height of the stair string it is generally necessary to stack the structural parts in multiple layers.
  • plate material is thus used with a random thickness which can be stacked to a thickness of dozens of layers. It is noted here that for a correct stacking of the structural parts at determined positions relative to the template, markings can be arranged on at least one side of the structural parts left free such that the markings of successive structural parts coincide with each other. The stacking of the structural parts can thus be carried out accurately in simple manner.
  • the template is placed horizontally prior to step c and vertical guide members are then placed for vertical stacking of the structural parts.
  • the template is herein manufactured twice and the vertical guide members connect onto the template on a bottom side and a top side.
  • the vertical guide members can consist for instance of slats, beams, tubes, cables etc.
  • the advantage of the vertical guide members is that the template acquires a more or less three-dimensional form, whereby purely vertical stacking of the structural parts is simplified.
  • the vertical guide members have sufficient rigidity, they can also be used to support the (partially) constructed assembly of structural parts. This is possible for instance by means of clamps with which the assembly is coupled to the vertical guide members.
  • the structural parts can be glued to each other.
  • the stair string can be covered on one or more sides.
  • covering materials are wood veneer, plastic veneer, varnish etc. It is noted that in practice the upper edge of the stair string can advantageously be covered with multiple layers of vertically placed wood veneer. The suggestion of a stair string made of solid wood can thus be created.
  • the invention further provides a method for manufacturing a staircase by assembling treads with at least one string manufactured with the method as described above. These treads can advantageously be manufactured connecting onto the template.
  • Such a staircase can be manufactured in relatively advantageous manner and has a very high degree of design freedom; any form of staircase is in principle relatively simple to realize.
  • the invention moreover provides a string of a staircase manufactured from a number of structural parts assembled in stacked manner, which structural parts consist of at least substantially form-retaining parts of plate material. At least one side of the assembly of structural parts is herein preferably covered with a covering layer. A staircase provided with at least one such stair string is also provided by the invention.
  • Figure 1 shows a block of wood 1 with an obliquely cut side 2 on which are arranged construction lines 3 which originate from a projection for manufacturing a curve or wreath piece.
  • a curve or wreath piece can be applied at a position where two straight stair strings meet, for instance at the position of a landing.
  • the curve or wreath piece must be released from the wooden block 1 with conventional wood-working techniques.
  • the manufacture in this way of more complex spatial forms of (parts of) stair strings is very complicated and labour-intensive.
  • Figure 2 shows a template 4 which forms a perpendicular projection onto a horizontal plane of a stair string in the situation of use.
  • Template 4 generally has an elongate and curved form. Template 4 can be manufactured from a random, form-retaining material. As also shown in the figure, template 4 can be built up from separate template parts 5,6 rigidly connected to each other.
  • Figure 3 shows template 4 placed on the ground 7.
  • a second template 8 Placed perpendicularly above template 4 is a second template 8 with a geometry identical to that of template 4.
  • the two templates 4,8 are joined together by beams 9 which function as guide members and support elements.
  • Structural parts 10 are stacked successively above template 4 in at least partially overlapping manner. These structural parts 10 are manufactured from plate material such that the form thereof corresponds with a part of template 4.
  • the successive structural parts 10 are glued to each other.
  • an assembly 11 of structural parts 10 which has a rough shape corresponding with the desired form of the stair string. In order to hold the assembly 11 of structural parts 10 in position, it is fixed to beams 9 in the figure using clamps 12.
  • the upper and lower edge can be brought into a smooth shape by sawing, planing and so on.
  • the thus processed assembly can be further finished, subject to the wishes of the client, with a single or multi-sided covering.
  • figure 4 shows a staircase 13 according to the invention with two stair strings 14,15, both having a complex spatial form which can however be produced in very controlled manner.
  • stair treads 16 use can likewise be made in advantageous manner of the templates 4,8 for manufacturing the stair strings 14,15, since these treads have to connect to the template in fitting manner.
