Description

Banda de señalización para suelos y procedimiento de fabricación.Signaling band for floors and manufacturing procedure

Objeto de la invenciónObject of the invention

La presente invención se refiere a una banda de señalización para suelos y procedimiento de fabricación para su uso como señalización horizontal para invidentes y minusválidos en general.The present invention relates to a band of floor signage and manufacturing procedure for use as horizontal signage for the blind and disabled in general.

Antecedentes de la invenciónBackground of the invention

En la actualidad existen diversos sistemas para facilitar el acceso y señalización de personas invidentes o con otras minusvalías.There are currently several systems for facilitate the access and signaling of blind people or with other handicaps

Los planes de accesibilidad para invidentes y discapacitados proponen diversas iniciativas destinadas a mejorar el uso de instalaciones y accesos a lugares públicos tales como estaciones de metro, estaciones de autobuses, edificios públicos y otros.Accessibility plans for the blind and disabled people propose various initiatives aimed at improving the use of facilities and access to public places such as metro stations, bus stations, public buildings and others.

En efecto, en algunos lugares donde circulan estas personas con minusvalías se pueden encontrar señalizaciones acústicas mediante altavoces o señalización horizontal mediante bandas en el suelo, que pueden ser seguidas mediante su tacto rugoso al paso o al bastón o su color llamativo y contrastado para personas con resto visual adecuado.Indeed, in some places where they circulate these people with disabilities can find signs acoustics by loudspeakers or horizontal signaling by bands on the ground, which can be followed by touch rough to the step or to the cane or its striking and contrasted color to people with adequate visual rest.

Por ejemplo en una estación de metro o tren las señales dispuestas comprenden la localización de escaleras, ascensores, el borde del andén y el acceso al primer vagón de tren, el cual puede estar provisto de unas entradas especiales para discapacitados. Estas bandas son de diversos colores (amarillo en bordes de andén accesos y salidas de escaleras y ascensores y anaranjado en la banda de delimitación del primer vagón). Las bandas pueden presentar el relieve en forma de topos o rayas, por ejemplo y mostrar una franja fotoluminiscente.For example in a subway or train station the arranged signals include the location of stairs, elevators, the edge of the platform and access to the first train car, which may be provided with special tickets for disabled. These bands are of different colors (yellow in platform edges access and exits of stairs and elevators and orange in the delimitation band of the first car). The bands they can present the relief in the form of moles or stripes, for example and show a photoluminescent strip.

Estas bandas pueden estar realizadas de dos formas diferentes. En una primera realización la banda se conforma como una tira de goma u otro material sintético prefabricado con los relieves y colores adecuados, que es cortada según la aplicación a la que vaya destinada. Posteriormente estos elementos se colocan en su lugar definitivo mediante adhesivos y/o tornillos de fijación al suelo. Estos elementos presentan una funcionalidad de visibilidad y "tacto" bastante buenas, sin embargo los sistemas de fijación anteriormente mencionados presentan problemas, ya que con el uso se acumula la suciedad por debajo y alrededor y al limpiar con máquina, el disco de limpieza acaba arrancando y rompiendo los bordes y la propia placa.These bands can be made of two different ways. In a first embodiment the band conforms as a rubber strip or other prefabricated synthetic material with the appropriate reliefs and colors, which is cut according to the application to which it is intended. Subsequently these elements they are placed in their definitive place by means of adhesives and / or screws of fixation to the ground. These elements have a functionality of visibility and "touch" quite good, however fixing systems mentioned above present problems, since with the use the dirt accumulates under and around and when cleaning with a machine, the cleaning disc ends up booting and breaking the edges and the plate itself.

Otro sistema consiste en la conformación del suelo mediante placas o losas convencionales de pavimento en las que las bandas se conforman mediante losas de relieve adecuado. Mediante esta conformación las bandas formadas por las losas especiales resultan muy resistentes, pero presentan un escaso efecto visual y el elemento fotoluminiscente es difícil de integrar. Además la colocación de bandas según este sistema en un lugar ya existente exige una profunda y costosa reforma que implica levantar el pavimento ya existente.Another system consists of shaping the floor by conventional paving slabs or slabs in the that the bands are formed by appropriate relief slabs. Through this conformation the bands formed by the slabs special ones are very resistant, but they have little effect Visual and photoluminescent element is difficult to integrate. In addition the placement of bands according to this system in a place already existing demands a deep and expensive reform that involves lifting the existing pavement.

Descripción de la invenciónDescription of the invention

La banda de señalización para suelos y procedimiento de fabricación de esta invención presenta una serie de particularidades técnicas destinadas a obtener una funcionalidad optimizada con una gran durabilidad de la banda una vez colocada.The signaling band for floors and manufacturing process of this invention presents a series of technical peculiarities intended to obtain functionality optimized with great durability of the band once placed.

En efecto, la banda está constituida por un compuesto de poliuretano fluorado sin disolventes cuya formulación comprende al menos las siguientes sustancias: poliol de poliéster ramificado y poliéter, poliisocianato de MDI (diisocianato de metileno), compuesto fluorado, compuestos ignifugantes, cargas y otros componentes.In effect, the band consists of a solvent-free fluorinated polyurethane compound whose formulation It comprises at least the following substances: polyester polyol branched and polyether, MDI polyisocyanate (diisocyanate methylene), fluorinated compound, flame retardant compounds, fillers and other components.

Más concretamente los porcentajes orientativos de estas sustancias son:More specifically the guidance percentages of these substances are:

--
poliol de poliéster ramificado y poliéter entre un 15% y un 25%,polyol of branched polyester and polyether between 15% and 25%,

--
poliisocianato de MDI (diisocianato de metileno) entre un 5% y un 15%,MDI polyisocyanate (diisocyanate methylene) between 5% and 15%,

--
compuesto fluorado entre un 5% y un 10%,fluorinated compound between 5% and a 10%

--
compuestos ignifugantes entre un 30% y un 50%,flame retardant compounds between 30% and 50%

--
siendo el porcentaje restante de cargas hasta completar composición.being the remaining percentage of charges until completed composition.

Estas cargas comprenden de microesferas de vidrio, sílice, corindón y/o pigmento.These charges comprise of microspheres of glass, silica, corundum and / or pigment.

La banda formada con este compuesto es muy resistente al desgaste y no se pude separar del suelo, ya que la unión es mediante una reacción química del propio compuesto con la superficie del suelo o pavimento, sin agentes intermedios ni adhesivos. Esta banda no permite que queden huecos por donde penetre la suciedad o se levante. El compuesto hace que la banda sea transpirable, resistente al desgaste por tráfico, las manchas y residuos que se puedan adherir, por ejemplo los chicles de goma de mascar, La banda obtenida es ignífuga con una resistencia al fuego con clasificación M-1.The band formed with this compound is very wear resistant and could not be separated from the ground, since the binding is by a chemical reaction of the compound itself with the floor or pavement surface, without intermediate agents or adhesives This band does not allow gaps to remain where it penetrates Dirt or get up. The compound makes the band Breathable, resistant to traffic wear, stains and residues that can adhere, for example rubber gum chewing, the band obtained is flame retardant with a fire resistance with M-1 classification.

El compuesto de la banda también puede comprender en su formulación un compuesto de estroncio como elemento fotoluminiscente, que queda incorporado de forma inseparable en la banda. De esta forma se puede configurar la banda con unas zonas de relieve y una zona central de efecto fotoluminiscente que permite su percepción adecuada en caso de falta accidental de iluminación (se puede llegar a conseguir unas propiedades fotoluminiscentes 590/84,3-7265 según DIN 67510).The band compound can also comprise in its formulation a strontium compound as photoluminescent element, which is incorporated in a way Inseparable in the band. This way you can configure the band with some relief areas and a central area of effect photoluminescent that allows its proper perception in case of accidental lack of lighting (you can get to get some photoluminescent properties 590 / 84.3-7265 according DIN 67510).

El tiempo de curado se puede regular mediante una sustancia aceleradora de dicha curación añadida a dicha composición según se estime necesario, reduciendo el tiempo de curado desde las 12 horas de curado convencional a hasta 3 minutos aproximadamente.Curing time can be regulated by an accelerating substance of said healing added to said composition as deemed necessary, reducing the time of Cured from 12 hours of conventional curing up to 3 minutes approximately.

El procedimiento de fabricación comprende la mezcla de los componentes del compuesto según la formulación anteriormente citada y su reacción. Se aplica el compuesto sobre la superficie de recepción en un momento cualquiera antes de la plena curación de dicho compuesto. Así, la banda conformada sobre la superficie de suelo o pavimento se adhiere o une mediante reacción química del compuesto con el material de dicha superficie receptora. Esto aporta una gran ventaja, ya que la banda se fija por unión directa y no mediante colas, adhesivos intermedios y/o unión mecánica convencional.The manufacturing process comprises the mixing of the components of the compound according to the formulation previously cited and its reaction. The compound is applied on the Reception surface at any time before full cure of said compound. Thus, the band formed on the floor or pavement surface adheres or joins by reaction chemistry of the compound with the material of said surface Receiver This provides a great advantage, since the band is fixed by direct bonding and not by glues, intermediate adhesives and / or conventional mechanical union.

En una primera forma de conformación, el compuesto de la banda se forma y cura parcialmente como elemento semielaborado en un molde de silicona, por ejemplo. Cuando el compuesto de la banda adquiere un estado sólido o semisólido que permite su manipulación (aproximadamente antes de las 12 horas de curado), se aplica sobre la superficie receptora. Durante el resto del curado, el compuesto de la banda en contacto con la superficie receptora se une a esta mediante una reacción química.In a first form of conformation, the Band compound is formed and partially cured as an element semi-finished in a silicone mold, for example. When he band compound acquires a solid or semi-solid state that allows handling (approximately before 12 hours of cured), is applied on the receiving surface. During the rest of curing, the band compound in contact with the surface receptor binds to it through a chemical reaction.

En una segunda forma de realización del procedimiento el compuesto de la banda se mezcla y reacciona iniciando la curación, procediéndose a la aplicación directa sobre la superficie receptora mediante un dispositivo adecuado, por ejemplo tal coma una extrusora, por ejemplo, conformándose los relieves, franjas y otros elementos de dicha banda.In a second embodiment of the procedure the band compound is mixed and reacts initiating the healing, proceeding to the direct application on the receiving surface by a suitable device, by example such as an extruder, for example, conforming the reliefs, stripes and other elements of said band.
