Definitions

  • the invention relates to a refurbishment element for a tread and a tread of a staircase.
  • a refurbishment can also already be caused by wanting to change the visual appearance of a staircase.
  • One possibility for example, is to fill up the worn area of a tread with a suitable leveling compound and subsequently stick a covering of plastic.
  • a profile is mounted so that forms a gap between the front edge of the tread and the profile, which is then filled with a filling material, such as a plastic mass.
  • the surfaces of the treads after performing the known remediation procedures are generally less resistant to wear.
  • An inventive refurbishment element for a tread has an upper layer and a carrier layer and is applied to the refurbishment of a worn tread on this.
  • the application of the redevelopment element on the step to be rehabilitated tread is preferably effected by applying to the worn tread a leveling compound, for example in the form of synthetic resin or firm foams, and then the redevelopment element is materially connected to the tread, wherein it is at the tread to a step, for example, a wooden staircase, a concrete core staircase or a stone staircase can act.
  • the top layer of the redevelopment element forms, with its upper side, the accessible surface of the redevelopment element, whereas the carrier layer is arranged on the side opposite the accessible surface of the upper layer.
  • the redevelopment element according to the invention is characterized, on the one hand, by the fact that the top layer is designed as a end grain layer.
  • end grain which is cut through transversely to its fiber direction, so that the fibers are directed substantially perpendicular to the accessible surface and to the carrier layer.
  • the technological advantage of end grain is in particular that this, for example, compared to long wood, is a lot of pressure-stable and thus can absorb higher compressive forces for longer periods and that it has a higher abrasion resistance than long wood. End grain is therefore particularly suitable for use in heavily used areas, especially when a walk with street shoes takes place.
  • end grain has optimized properties with regard to its fire behavior, thermal insulation properties and sound insulation.
  • the redevelopment element according to the invention is characterized in that the carrier layer is designed as a tension-resistant reinforcing layer and that the upper layer has a cohesive, planar connection with the carrier layer.
  • the compound is inventively designed so that can be absorbed by these transverse thrust forces between the upper layer and the carrier layer.
  • Such transverse thrust forces occur, in particular, when stepping on the tread and causing local upper bend deflection.
  • the cohesive connection between the top layer and the carrier layer is provided by gluing the two layers together.
  • Such an intermediate layer can consist, for example, of a mesh fabric, a film or a thin layer of solid material and serves, in particular, to optimize the connection and to simplify the bonding of the top layer to the carrier layer.
  • the carrier layer can also be designed as a multilayer.
  • the transverse thrust forces receiving connection between the upper layer and the tensile strength carrier layer is particularly advantageous manner, the disadvantage of the end grain that this only a low bending and tensile strength, in particular solved by the occurring in the upper layer at the bottom Tensile stresses are derived by the compound in the tensile carrier layer. It is assumed that the redevelopment element in the lateral, not beaten areas of a tread to be rehabilitated finds a stable Auflagerung, but rather is pressure-loaded in the central area by the use of foot. The end grain layer acts as a pressure zone.
  • the restoration element according to the invention by absorbing the tensile stresses in the carrier layer, has the further advantage that relatively small layer thicknesses of the upper layer are realized, whereby in particular the necessary total height of the restoration element can be kept low.
  • This turns out to be particularly advantageous in a renovation of a wooden staircase, as this eliminates the need for elaborate processing of the step to be rehabilitated and at the same time the existing increment of the wooden staircase in the entrance or exit can be largely maintained.
  • the redevelopment element according to the invention offers the technological advantage that, by using end grain as a material for the top layer, the real wood appearance of the tread is maintained or improved by the end grain view, as the case may be.
  • the renovation element according to the invention thus makes it possible to rehabilitate a tread of a wooden staircase so that it has a wear-resistant surface after the renovation and that at the same time a end grain look of the surface is provided.
  • the top layer has a thickness in the range between 2 and 12 millimeters.
  • the carrier layer consists of a fiber composite material.
  • fiber composites all fiber composites can be used according to the invention; in particular glass fiber reinforced plastics (GRP) or carbon fiber reinforced plastics (CFRP) are used.
  • GRP glass fiber reinforced plastics
  • CFRP carbon fiber reinforced plastics
  • the use of a fiber composite material for the carrier layer has in particular the technological advantage that the carrier layer can be provided with a high tensile strength and at the same time very easily and with a relatively small layer thickness.
  • the total weight of the renovation element and its construction height can be kept low on a tread to be rehabilitated.
  • the carrier layer is only partially formed from a fiber composite material.
  • the fiber composite material for example in the form of tensile fiber strands or fabrics, be embedded in a less tensile base material. Fiber mats are also included, whereby their matrix material can at the same time provide the connection to the upper layer by gluing.
  • An equally advantageous embodiment of the invention provides that the carrier layer is formed as a metal plate.
  • the carrier layer can be made very thin and manufactured inexpensively as a particular advantage.
  • corrugations of the end grain layer are effectively avoided as a top layer.
  • steel or stainless steel are used as the metal material, although according to the invention it is also possible to use other, high-tensile metal materials.
  • the carrier layer consists in a particularly advantageous development of the invention of an HPL material (high pressure laminates).
  • HPL materials are known as such from the prior art and are laminates in which, for example, paper materials or textile fibers with Synthetic resins are added and pressed under high pressure with further layers.
  • HPL materials have, inter alia, a high tensile and flexural strength, which is why they are particularly suitable for use as a carrier layer of a redevelopment element according to the invention.
  • HPL material can be produced within the HPL material low producible materials, in particular paper, and so the costs of providing a refurbishment element according to the invention are kept low.
  • an advantageous variant of the invention further provides that the upper layer is formed from a plurality of Einzelhirnholzianan.
  • the single-grain wood elements can be arranged one above the other both side by side and additionally, at least partially.
  • the single-grained wood elements are preferably connected to the carrier layer on their side surfaces, for example by gluing, together with one another and on their underside.
  • the individual elements can either be connected individually to the carrier layer and to one another or to one another before joining to the carrier layer, in order subsequently to be connected to the carrier layer as the entire top layer.
  • the single-grain wood elements can also be connected first to the intermediate layer and then to the carrier layer.
  • the intermediate layer is present as an integral part of the upper layer before joining the upper and carrier layer, wherein the redevelopment element is formed in this case three-layered.
  • the upper layer of the remediation element according to the invention is impregnated in a preferred development, at least on the upper side water and / or dirt repellent.
  • the upper side of the upper layer represents the accessible side of the redevelopment element and thus the tread area of the renovated tread.
  • the impregnation can be provided, for example, by an oil or wax to be applied at least to the upper side of the remediation element.
  • a tread according to the invention has an upper layer, a carrier layer and a substructure.
  • the substructure is understood to be the region of the tread on which the carrier layer and the upper layer are supported and by means of which the loads are taken up and transmitted to the carrying structure of the staircase, for example the cheeks or spars.
  • the base of the tread can be designed differently, depending on the stairway structure.
  • the substructure has a support element on which the carrier layer preferably rests over its entire surface.
  • the support element is formed for example by a wooden plate whose dimensions are adapted to the carrier layer.
  • the substructure is connected to the side of the carrier layer opposite the top layer, with the latter preferably being able to be provided by gluing.
  • the tread can be present in particular by placing a restoration element on an existing substructure, or as a total newly created tread with the structure described by the features.
  • Fig. 1 shows an inventive refurbishment element for rehabilitating a worn tread 7, wherein the refurbishment element is applied to the tread 7.
  • the tread 7 itself is not the subject of the redevelopment element.
  • the remediation element according to the invention has an upper layer 1 and a carrier layer 2, wherein the upper layer 1 is formed by a end grain layer and wherein the carrier layer 2 is designed as a tension-resistant reinforcement layer.
  • end grain wood for the top layer 1 offers, in particular, the technological advantage that a particularly pressure-stable and wear-resistant surface of the tread 7 can be provided after its rehabilitation.
  • the upper layer 1 has a material-fit and, in particular, surface-formed connection 3 to the carrier layer 2, wherein the connection 3 is designed such that it adopts transverse thrust forces, for example upon entering the tread in the upper layer 1, and transfers these into the carrier layer 2 derives.
  • the compound 3 between the upper layer 1 and the carrier layer 2 is provided in the present exemplary embodiment by a bonding compound, for example made of synthetic resin, and is present over the full area between the upper layer 1 and the carrier layer 2.
  • a bonding compound for example made of synthetic resin
  • the carrier layer 2 consists of a fiber-reinforced material, in particular of a fiberglass mat.
  • GRP GRP
  • a particularly efficient carrier layer 2 can be provided, which at the same time has a low weight and which is further distinguished by a small layer thickness.
  • the rehabilitation element according to the invention has only a relatively low total height and therefore the step to be rehabilitated 7 does not have to be elaborately processed or removed before applying the redevelopment element in order to maintain the required step height after the renovation.
  • the renovation element according to the invention has the particular advantage that the use of end grain wood can preserve the real wood appearance of the tread.
  • Fig. 2 shows a step according to the invention, in particular designed as a central staircase wooden staircase.
  • the tread has an upper layer 1 as end grain layer, a tensile carrier layer 2 and a base 4.
  • the upper layer 1 has a cohesive, planar connection 3 to the carrier layer 2, wherein the connection 3 in the present case is designed so that can be absorbed by these transverse thrust forces.
  • the carrier layer 2 is on the side facing away from the upper layer 1 side, in particular the entire surface connected to the substructure 4, wherein the substructure 4 in the embodiment according to Fig. 2 is formed solely by a support element and wherein the connection between the carrier layer 2 and the support element is made.
  • the support structure 5, here with a central spar 8 is not part of the tread.
  • the support element is designed as a base as a wooden plate and bolted to the support structure 5.
  • connection between the carrier layer 2 and the substructure 4 as a support element is in the present case also formed materially.
  • both of the redevelopment element and the tread, the carrier layer is formed multi-layered.
