DESCRIPCIÓN DESCRIPTION
Pieza prefabricada para la construcción de escaleras y bancadas. Prefabricated piece for the construction of stairs and benches.
Sector de la técnica. Technical sector.
La presente invención se refiere a una pieza prefabricada para la construcción de escaleras y bancadas, aplicable en el sector de la construcción. The present invention refers to a prefabricated piece for the construction of stairs and benches, applicable in the construction sector.
Estado de la técnica anterior Prior art state
Uno de los inconvenientes que se plantea habitualmente en el sector de la construcción es el replanteo de las escaleras ya que en función del espacio disponible dichas escaleras pueden tener una mayor o menor inclinación, sin embargo las dimensiones de la huella o parte horizontal del escalón y la contrahuella o parte vertical del escalón deben mantenerse dentro de unos valores determinados para que la escalera resulte cómoda y segura. One of the problems that usually arises in the construction sector is the redesign of stairs since, depending on the available space, said stairs may have a greater or lesser inclination, however the dimensions of the tread or horizontal part of the step and The riser or vertical part of the step must be kept within certain values so that the staircase is comfortable and safe.
Dada la dificultad que supone la distribución de los peldaños y el cálculo de las dimensiones de dichos peldaños para que la suma de sus dimensiones horizontales y verticales coincidan con la altura y la longitud de la escalera, dichos peldaños se construyen en la propia obra, lo que permite un cierto juego con las longitudes de la huella y la contrahuella, aunque en algunos casos dichas longitudes no se ajusten a las dimensiones recomendadas, que en el caso de la huella es de 26 a 30 cm y en el caso de la contrahuella es de 16 a 17 cm. Given the difficulty involved in the distribution of the steps and the calculation of the dimensions of said steps so that the sum of their horizontal and vertical dimensions coincides with the height and length of the staircase, said steps are built on site, which which allows a certain play with the lengths of the tread and the riser, although in some cases these lengths do not fit the recommended dimensions, which in the case of the tread is 26 to 30 cm and in the case of the riser it is from 16 to 17 cm.
El problema técnico que se plantea es el desarrollo de una pieza prefabricada para la construcción de escaleras y bancadas, que facilite el replanteo y simplifique la construcción de la escalera o bancada. The technical problem that arises is the development of a prefabricated piece for the construction of stairs and benches, which facilitates the layout and simplifies the construction of the staircase or bench.
Explicación de la invención. Explanation of the invention.
La pieza prefabricada para la construcción de escaleras y bancadas objeto de esta invención presenta unas características formales y dimensionales que permiten resolver de forma satisfactoria el problema planteado anteriormente, y construir de forma rápida y sencilla escaleras con diferentes inclinaciones, utilizando piezas ¡guales y de unas determinadas dimensiones. The prefabricated piece for the construction of stairs and benches that is the object of this invention has formal and dimensional characteristics that allow the problem posed above to be satisfactorily resolved, and to quickly and easily build stairs with different inclinations, using identical pieces of the same size. certain dimensions.

HOJA RECTIFICADA (REGLA 26) De acuerdo con la invención, esta pieza prefabricada para la construcción de escaleras y bancadas, comprende un cuerpo prismático recto con un ala horizontal y un ala vertical sensiblemente perpendiculares; comprendiendo dichas alas una superficie interior y una superficie exterior reversibles, que conforman indistintamente la cara vista o la cara oculta de la huella y de la contrahuella de un escalón. GRINDED SHEET (RULE 26) According to the invention, this prefabricated piece for the construction of stairs and benches comprises a straight prismatic body with a horizontal wing and a vertical wing that are substantially perpendicular; said wings comprising a reversible interior surface and an exterior surface, which either form the visible face or the hidden face of the tread and riser of a step.
La configuración de esta pieza, simplemente mediante dos alas perpendiculares sin ángulos ni nervios de refuerzo en su superficie interior, le proporciona un carácter reversible, de modo que el ala vertical o contrahuella de la pieza puede proyectarse desde el ala horizontal hacia la zona superior, conformando la superficie interior de la pieza prefabricada la cara vista del escalón, o proyectarse hacia la zona inferior conformando en este caso la superficie exterior de la pieza prefabricada la cara vista del escalón. The configuration of this piece, simply by means of two perpendicular wings without angles or reinforcing ribs on its interior surface, provides it with a reversible character, so that the vertical wing or riser of the piece can project from the horizontal wing towards the upper area, the inner surface of the prefabricated piece forming the visible face of the step, or projecting towards the lower area, in this case the outer surface of the prefabricated piece forming the visible face of the step.
De acuerdo con la invención las alas horizontal y vertical del escalón tienen un espesor comprendido entre 2,5 y 3,5 cm y en consecuencia la longitud de la superficie exterior de dichas alas es mayor que la de superficie interior, por lo que el montaje de las piezas prefabricadas en una u otra posición proporciona una variación de las longitudes nominales de la huella y la contrahuella. According to the invention, the horizontal and vertical wings of the step have a thickness between 2.5 and 3.5 cm and consequently the length of the outer surface of said wings is greater than that of the inner surface, so the assembly of the prefabricated parts in one position or another provides a variation of the nominal lengths of the tread and riser.
Adicionalmente cabe mencionar que la pieza prefabricada, conformante de cada escalón, puede disponerse enfrentada, o superpuesta en mayor o menor medida, al ala horizontal de la pieza o escalón inmediato inferior, lo que permite conformar con las piezas prefabricadas, de dimensiones fijas, escalones cuya huella y contrahuella cubran holgadamente el rango de dimensiones recomendadas. Additionally, it is worth mentioning that the prefabricated piece, which makes up each step, can be arranged facing, or superimposed to a greater or lesser extent, on the horizontal wing of the piece or step immediately below, which allows the formation of steps with the prefabricated pieces, of fixed dimensions. whose tread and riser comfortably cover the range of recommended dimensions.
De acuerdo con la invención, la superficie exterior del ala horizontal tiene una longitud comprendida entre 28 y 32 cm y la superficie exterior del ala vertical tiene una longitud comprendida entre 16 y 20 cm. According to the invention, the outer surface of the horizontal wing has a length between 28 and 32 cm and the outer surface of the vertical wing has a length between 16 and 20 cm.
Preferentemente, la pieza prefabricada puede estar conformada en mortero reforzado con fibra de vidrio, presentando un acabado liso adecuado para mantenerse en posición visible, o estar conformada en hormigón armado con varilla metálica, presentando en este caso un acabado rugoso, adecuado para ser revestido. Preferably, the prefabricated piece can be made of fiberglass-reinforced mortar, presenting a smooth finish suitable to remain in a visible position, or be formed of concrete reinforced with metal rod, presenting in this case a rough finish, suitable for being coated.
