Definitions
- the present invention relates to a method for making aluminium section fittings for floors.
- dilating joints to compensate for any deformations caused by temperature and moisture variations, and are further used other joints to connect floor portions arranged at different levels.
- the aim of the present invention is to provide such a section fitting making method allowing to make section fittings having improved aesthetic and functional characteristics, that is constructional and aesthetic characteristics greatly improved with respect to those of existing section fittings.
- a main object of the invention is to provide such a method allowing to make faced or "ennobled" aluminium section fittings.
- Another object of the present invention is to provide such a method allowing to easily and quickly make section fittings which, owing to their specifically designed constructional features, are very reliable and safe in operation.
- Yet another object of the present invention is to provide such a method which can be carried out starting from easily commercially available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
- the method for making aluminium section fittings for floor has been specifically designed for making, by coating operations, aluminium section fittings for floors, such as dilating section fittings, of the type shown in figures 1-3 , hanging section fittings, of the type shown in figures 4-6 , C section fittings, stepped section fittings, as well as yet other application section fittings.
- the method according to the present invention comprises a starting step of making a raw section fitting, by a die extruding operation, thereby providing an extruded section fitting having any desired or target shape and cross section.
- the figures show, by way of an example, a dilating section fitting 1 and a hanging section fitting 3.
- the method provides to coat the extruded section fitting by a coating natural and/or pre-composite coating veneer.
- coating veneers having a thickness of 4/10 mm, and made of any desired veneer material, such as: maple, walnut, cherry tree, beech-wood, wengé, teak, ebony, bamboo, zebrano and so on.
- a premium flexible paper material having a thickness of. 1/10 mm, with a wood-like pattern, in several colors and essences, but also with fancy and different finishings (colors, metals, fibers and so on).
- the natural wood or paper coating layer has been generally indicated by the reference number 2.
- a third operating step of the inventive method provides to bond or connect the extruded section fitting and wood veneer material by glueing them, by a PUR based hotmelt adhesive material, that is an inactivated mixture of polyurethane, which is hot applied on the extruded section fitting, at a temperature of about 100/140°C.
- the above adhesive material differently from those based on EVA and containing thermoplastics resin, will cross-link thereby providing a unfusible polyurethane molecule.
- An example of a preferred adhesive comprises that adhesive material commercially called EP 12 602.00 , made by the company Jowatherm-Reaktant.
- the inventive method further comprises a fourth operating step to perform a painting operating cycle, carried out by applying an insulating acrylic primer and two further coats of a transparent mat anti-scratching polyurethane "diamond" material.
- the insulating acrylic primer comprises preferably a two-component polyurethane paint, that is a hydroxylated and an isocyanatic part.
- a last operating step of the inventive method comprises applying a transparent protective film, generally indicated by the reference number 4 in the figures.
- the used protective film in other words, will provide a mean for preserving the aesthetic properties of the above made section fitting.
- the invention provides a method allowing to easily and inexpensively make floor aluminium section fittings having improved technical and aesthetic characteristics.
- the used materials, as well as the contingent size and shapes can be any, according to requirements.

Claims (9)
- Procédé de fabrication de profilés en aluminium extrudés (1, 3) pour planchers, ledit procédé comprenant les étapes suivantes :a) la fabrication d'un profilé brut d'aluminium grâce à une opération d'extrusion d'aluminium, afin d'obtenir un profilé d'aluminium ayant n'importe quelle forme et n'importe quelle section désirées ;b) le revêtement dudit profilé par un placage de revêtement consistant en une matière naturelle et/ou pré-composite ou synthétique, telle que le papier, le PVC et le polypropylène ;c) l'encollage du profilé avec une matière adhésive thermofusible et placage d'un revêtement;caractérisé en ce que ledit procédé comprend les autres étapes suivantes :d) l'application d'une peinture protectrice sur le placage de revêtement ; ete) l'application d'un autre film protecteur transparent provisoire sur le placage peint, etf) en ce que ladite matière adhésive thermofusible est une matière adhésive thermofusible à base de mélange de polyuréthane inactivé qui est appliquée à chaud sur ledit profilé à une température d'environ 100/140 °C, ce qui provoque la réticulation de ladite matière adhésive afin d'obtenir des molécules de polyuréthane non liquéfiable.
- Procédé selon la revendication 1, caractérisé en ce que ladite étape de revêtement est réalisée en utilisant des matières de placage de revêtement naturelles ayant une épaisseur de 4/10 mm constituées d'essences formant matières de revêtement naturelles telles que l'érable, le noyer, le cerisier, le hêtre, le wengé, le teck, l'ébène, le bambou et le zebrano.
- Procédé selon la revendication 1 ou 2, caractérisé en ce que ladite étape de revêtement est réalisée en utilisant une matière de placage de revêtement en papier synthétique souple de première qualité ayant une épaisseur de 1/10 mm, avec des motifs ressemblant au bois, en plusieurs couleurs et essences, ainsi qu'avec différents décors et différentes finitions.
- Procédé selon la revendication 1, caractérisé en ce que ladite matière adhésive thermofusible comprend un composé adhésif disponible dans le commerce sous la marque commerciale EP 12 602.00, auprès de la société Jowatherm-Reaktant.
- Procédé selon la revendication 1, caractérisé en ce que ladite étape de peinture est réalisée en utilisant une couche primaire isolante en acrylique et deux couches d'une matière de type « Diamant » en polyuréthane anti-rayure incolore mat.
- Procédé selon la revendication 5, caractérisé en ce que ladite couche primaire isolante en acrylique comprend une peinture polyuréthane à deux composants comprenant une partie hydroxylate et une partie isocyanate.
- Procédé selon la revendication 1, caractérisé en ce que ladite étape de peinture donne un profilé peint qui est conforme aux exigences en matière de résistance au piétinement de la classe AC4.
- Procédé selon la revendication 1, caractérisé en ce que ledit film protecteur transparent ou incolore est conçu pour protéger ledit profilé contre les détériorations susceptibles de se produire lors des opérations de découpe et d'expédition.
- Profilé en aluminium (1, 3) pour planchers, ledit profilé étant revêtu d'un placage de revêtement consistant en une matière naturelle et/ou pré-composite ou synthétique, telle que le papier, le PVC et le polypropylène, le placage de revêtement étant collé sur le profilé au moyen d'une matière adhésive thermofusible, caractérisé en ce que ledit profilé en aluminium est fabriqué grâce à un procédé selon les revendications 1 à 8, ladite matière adhésive thermofusible étant une matière adhésive thermofusible à base de mélange de polyuréthane inactivé qui a été appliquée à chaud sur ledit profilé à une température d'environ 100/140 °C, ce qui provoque la réticulation de ladite matière adhésive afin d'obtenir des molécules de polyuréthane non liquéfiable, le placage de revêtement étant lui-même revêtu d'une peinture protectrice et le placage peint étant revêtu d'un autre film protecteur transparent provisoire.
