Description
Sistema de protección provisional para bordes de obras y construcciones.Provisional edge protection system Works and constructions.
La invención que se protege en esta patente de invención, consiste en un sistema de protección provisional para obras y construcciones, en concreto de los bordes abiertos sin paredes ni muros de las edificaciones, para minimizar las caídas a distinto nivel de altura.The invention that is protected in this patent of invention, consists of a provisional protection system for works and constructions, specifically of open edges without walls or walls of buildings, to minimize falls to different height level.
Se trata, por tanto, de un sistema que consta de diversas barandillas y balaustres que se aplica en obras en construcción o en mantenimiento de forma temporal durante la duración de dichos trabajos para evitar las caídas y accidentes laborales del personal así como de la caída de objetos y materiales de obra que se suceden de forma imprevista, y con la finalidad de proteger a trabajadores y a los bienes y personas de los alrededores de éstas.It is, therefore, a system consisting of various railings and balusters that are applied in works in temporary construction or maintenance during the duration of said work to avoid falls and accidents personnel work as well as the fall of objects and materials of work that happen unexpectedly, and with the purpose of protect workers and surrounding property and people of this.
La utilización de varios sistemas de protección provisional de los bordes de las obras ya es conocida y está extendido con diversas configuraciones. Sin embargo, los diversos montajes estructurales de los sistemas y de los dispositivos varían en función tanto de aspectos técnicos como por sus aplicaciones. A tal efecto, con la presente invención se logra un sistema más ventajoso frente a los ya conocidos por razón de sus características funcionales en orden a su rapidez de montaje, a su adaptabilidad a todo tipo de obras y perímetros arquitectónicos, su seguridad laboral y sus características de conjunto compacto y robusto.The use of several protection systems provisional of the edges of the works is already known and is Extended with various configurations. However, the various structural assemblies of systems and devices vary depending on both technical aspects and their applications. TO such effect, with the present invention a more system is achieved advantageous compared to those already known because of their characteristics functional in order to its rapidity of assembly, its adaptability to all kinds of works and architectural perimeters, your safety labor and its characteristics of compact and robust set.
Así, son ya conocidos y divulgados sistemas rudimentarios como vallas, barandillas, tablones en madera o metálicos, puntales, redes, rejas y resguardos, etc... Todos ellos como medios ya divulgados y habituales en el sector de la construcción y rehabilitación de obras y edificios, que se fundamentan y responden sobre limitaciones funcionales y operativas que no cumplen con los criterios y ensayos de normalización técnica industrial sobre seguridad en las obras actuales.Thus, systems are already known and disclosed rudimentary as fences, railings, planks in wood or metal, struts, nets, bars and guards, etc ... All of them as media already disclosed and customary in the sector of construction and rehabilitation of works and buildings, which they base and respond on functional and operational limitations that do not meet the criteria and technical standardization tests industrial safety on current works.
En España, la normativa vigente de medidas preventivas a las caídas de altura que regula el Real Decreto 1627/1997 sobre las "Disposiciones mínimas de seguridad y salud en las obras de construcción" y la "Ordenanza General de Seguridad e Higiene en el Trabajo" (O.M. 9 de marzo de 1971); y que se reducen y limitan a "protecciones por barandillas, rejas u otros resguardos que completen la protección hasta 90 cm sobre el piso y que sean capaces de resistir una carga mínima de 150 kg por metro lineal", han quedado ya desfasadas tanto por las proporciones de las nuevas obras arquitectónicas como por los modernos medios y técnicas utilizadas en la edificación.In Spain, the current regulation of measures preventive to the falls of height that regulates the Royal Decree 1627/1997 on the "Minimum health and safety provisions in the construction works "and the" General Security Ordinance and Hygiene at Work "(O.M. March 9, 1971); and that reduce and limit to "protections by railings, railings or other guards that complete the protection up to 90 cm above the floor and that are capable of withstanding a minimum load of 150 kg per meter linear ", have already been outdated by both the proportions of the new architectural works as by modern means and techniques used in building.
Con el espíritu de adaptarse a la nueva realidad laboral y a la armonización europea de prevención de riesgos laborales se promulgó la reciente NORMA UNE-EN 13374 (2004) sobre Sistemas provisionales de protección de borde. Dicha norma establece unos ensayos y métodos clasificando los grados de protección en las siguientes categorías en función a su capacidad de resistir y sobre su diseño (resistencia a carga estática y dinámica, espesores y valores elásticos de materiales de acero, madera y aluminio, recomendaciones etc...):With the spirit of adapting to the new reality Labor and European harmonization of risk prevention Labor was promulgated the recent UNE-EN 13374 (2004) on Provisional Edge Protection Systems. Bliss standard establishes some tests and methods classifying the degrees of protection in the following categories based on their ability to resist and on its design (static and dynamic load resistance, elastic thicknesses and values of steel, wood and aluminum, recommendations etc ...):
- --
- Protección Clase A: Apoyo de una persona inclinada sobre la protección o caminando apoyada en ella y detención de una persona que caminado o por caída choca contra la misma. Protection Class A : Support of a person leaning on the protection or walking supported by it and detention of a person who walked or falls crashes into it.
- --
- Protección Clase B: Capaces de soportar situaciones de la clase A y la detención de la caída de una persona que se desliza por una superficie inclinada. Protection Class B : Capable of withstanding situations of class A and stopping the fall of a person who slides on an inclined surface.
- --
- Protección Clase C: Detención de una persona que desliza por una pendiente fuerte. Class C Protection : Detention of a person sliding down a steep slope.
