Description

DESCRIPCIÓN DESCRIPTION
PROTECCIÓN COLECTIVA Y SEÑALIZACIÓN DE REGISTROS EN EDIFICACIÓN Y OBRA CIVIL COLLECTIVE PROTECTION AND SIGNALING OF RECORDS IN BUILDING AND CIVIL WORKS
Sector de la técnica Technical sector
Destinado al sector industrial tanto de obra civil como edificación, así como a los fabricantes de equipos de prevención de riesgos laborales. Aimed at the industrial sector of both civil engineering and building, as well as manufacturers of occupational risk prevention equipment.
Antecedentes Background
Es conocido que tanto en edificación como en obra civil se llevan a cabo diferentes instalaciones como las redes eléctricas, de comunicación, de agua potable o de saneamiento, todas ellas comparten una distribución mediante una red en la cual existen diferentes puntos de registro y mantenimiento. Dada la natural actividad de las obras muchos de estos puntos de registro permanecen sin señalizar y sin proteger, exponiendo a cualquier trabajador, viandante o vehículo a un posible accidente. It is known that both in construction and in civil works, different installations are carried out, such as electrical, communication, drinking water or sanitation networks, all of which share a distribution through a network in which there are different registration and maintenance points. Given the natural activity of the works, many of these registration points remain unmarked and unprotected, exposing any worker, pedestrian or vehicle to a possible accident.
Si bien esto puede ocurrir en registros de pequeño tamaño la mayor peligrosidad a priori que representa la abertura de un pozo lleva a que este sea tapado de forma provisional con pesadas tapas de hormigón o plancha metálica, tableros de madera, palés etc. Although this can occur in small manholes, the greater a priori danger that the opening of a well represents leads to it being temporarily covered with heavy concrete covers or metal plates, wooden boards, pallets, etc.
El estado de la técnica revela diferentes soluciones para su tapado definitivo en las que la tapa o bien se articula con respecto a un marco, se deposita sobre este o finalmente se asegura mediante tornillos o cierres de seguridad no aportando una solución técnica al problema planteado. The state of the art reveals different solutions for its final covering in which the cover is either articulated with respect to a frame, is deposited on it or is finally secured by means of screws or security closures, not providing a technical solution to the problem posed.
No son conocidas por tanto invenciones que resuelvan ventajosamente el problema técnico como la invención preconizada. Objeto Therefore, there are no known inventions that advantageously solve the technical problem like the recommended invention. Object
Proporcionar medios para garantizar la protección colectiva y señalización frente a caídas a distinto nivel que pueden provocar las diferentes aberturas tanto de pozos como de otros registros. Proporcionar una medida de fácil instalación, recuperable y que comprenda medios de señalización. Proteger de la caída de material como áridos al pozo o registro. Que realice la función de señalización. Que proteja de la entrada de agua de lluvia, evitando acumulación en el registro y canalización. Provide means to guarantee collective protection and signaling against falls at different levels that can be caused by the different openings of both wells and other manholes. Provide a measure that is easy to install, recoverable and that includes signaling means. Protect from the fall of material such as aggregates into the well or manhole. That performs the signaling function. That protects from the entry of rainwater, avoiding accumulation in the register and channeling.
Descripción detallada de la invención Detailed description of the invention
Tal y como se ha reflejado en el estado de la técnica las medidas empleadas en general no evitan el riesgo de forma eficaz, ni ofrecen garantías de fijación y resistencia generando en muchas ocasiones riesgos adicionales. De otro lado los registros y dentro de estos los pozos se encuentran en ocasiones en viales y presentan escasa visibilidad lo que amplía la posibilidad de tener un accidente. Para todo ello la protección colectiva y señalización de registros en edificación y obra civil, en adelante la protección, dispone de medios para proteger un registro o pozo al disponer de una porción de material de forma laminar cuyo tamaño y geometría es proporcionada a la abertura que se pretende proteger en función de la sección que presenta la abertura en su cota superior, ya sea esta circular o poliédrica. Su fijación se realiza de un lado mediante al menos tres elastómeros que emergen de la cara de la protección en contacto con el registro cuya posición genera un ajuste con apriete contra las paredes de éste, de otro lado es posible atornillar la tapa al presentar próximo a su perímetro de una pluralidad de agujeros a través de los cuales se introducen tornillos convencionales fijando la protección. La visibilidad de la protección es lograda mediante al menos una superficie reflectante ubicada en un chaflán perimetral del que dispone la porción laminar descrita, presenta así mismo de un elemento de señalización como un cono o un hito vial centrado en el cuerpo laminar descrito; este elemento de señalización puede formar parte de la protección o ser incorporado y retirado de esta mediante medios convencionales como la unión mediante tornillos. As reflected in the state of the art, the measures used in general do not avoid risk effectively, nor do they offer guarantees of fixation and resistance, often generating additional risks. On the other hand, the records and within these the wells are sometimes found on roads and have poor visibility, which increases the possibility of having an accident. For all this, the collective protection and signaling of manholes in building and civil works, hereinafter protection, has means to protect a manhole or well by having a portion of material in a laminar shape whose size and geometry is proportional to the opening that It is intended to protect depending on the section that the opening presents at its upper level, whether it is circular or polyhedral. Its fixing is done on one side by means of at least three elastomers that emerge from the face of the protection in contact with the register whose position generates a tight fit against the walls of the latter, on the other hand it is possible to screw the cover as it is close to its perimeter of a plurality of holes through which conventional screws are introduced fixing the protection. The visibility of the protection is achieved by means of at least one reflective surface located on a perimeter chamfer of the described laminar portion, it also presents a signaling element such as a cone or a road milestone centered on the described laminar body; This signaling element can form part of the protection or be incorporated and removed from it by conventional means such as screw connection.
Se han previsto versiones en las que el dorso o cara en contacto de la protección contra el registro presenta una pluralidad de agujeros que cooperan con unos pasadores que son insertados mediante apriete, estos pasadores sobresalen introduciéndose en la cavidad del registro de tal forma que evitan que la protección se desplace en el plano horizontal cuando esta no es atornillada, esta función posibilita una solución técnica provisional cuando por ejemplo existe una tapa rota en un vial o directamente se carece de ella permitiendo cubrir y proteger la abertura de forma rápida y sencilla a la espera de una reparación oportuna. U otras en las que se dispone de medios de indicación luminosos en el chaflán y/o en su elemento de señalización. Versions have been provided in which the contacting back or side of the anti-registration protection has a plurality of holes that cooperate with pins that are inserted by pressing, these pins protrude Introducing itself into the registration cavity in such a way that it prevents the protection from moving in the horizontal plane when it is not screwed, this function enables a provisional technical solution when, for example, there is a broken cap on a vial or it is directly lacking, allowing cover and protect the opening quickly and easily while waiting for a timely repair. Or others in which there are luminous indication means on the chamfer and/or on its signaling element.
La protección colectiva y señalización de registros en edificación y obra civil está realizada de forma preferente en plástico por sus buenas propiedades y coste, se ha prevista que su dorso presente diferentes nervaduras con las que aportar resistencia aligerando la protección, así como de al menos un asa (no representada) para su transporte. The collective protection and signaling of records in building and civil works is preferably made of plastic due to its good properties and cost, it has been foreseen that its back has different ribs with which to provide resistance by lightening the protection, as well as at least one handle (not shown) for transport.
