Definitions

  • the object of the present invention refers to a flexible trap door for access platforms.
  • the EN-12810-1 2003 scaffolding Standard considers two ways to pass from one level to another:
  • the EN 12811-1 Standard in point 5.8.3, specifies: "The free dimensions of the access opening on a platform shall be at least 0.45m in width, measured transversally across the platform and
  • the load stipulated by the EN 12811-1 2003 Standard corresponds to class 3, that is to say, 2.0 KN/m 2 .
  • the present invention refers to a flexible trap door fastened to an access platform, that, when pushed by the worker's helmet, opens by rolling up and stays open while passing through the hole. Closing is "automatically” and progressively caused once the worker has gone through. Once closed, it may be used as a work surface, since it is strengthened by a cross-directional rigid reinforcement, allowing it to support the working load.
  • This flexible trap may be used for access platforms in general and more preferably for scaffolding access platforms.
  • the trap door consists of a flexible, lengthwise rubber plate, cross- directionally reinforced inside, which enables it to open and support the working load of 2.0 KN/m 2 stipulated by the EN 12811-1 2003 Standard.
  • the materials that may be used are very varied, but have to fulfil the following requirements:
  • the quantity may be continuously cast or laminated, both in one direction as the other.
  • the continuous lamination must be with heat in the remoulding process, so that the crosswise reinforcement sticks to the rubber.
  • Figure 1 Trap door opening lengthwise along the platform.
  • Figure 2 Trap door opening crosswise across the platform.
  • FIG. 3 Flexible trap door: rubber body (1 ), access platform (2), rigid cross-directional reinforcement (3), tape (4) and lock (5).
  • Figure 4 Upwards sequence from one level to another.
  • Figure 5 Downwards sequence from one level to another.
  • Figure 6 Cross-directional reinforcement.
  • Figure 7 Initial section of the flexible trap door according to an embodiment method.
  • Figure 8 End section of the flexible trap door according to an embodiment method.
  • Figure 9 Arrangement of the flexible trap door according to an embodiment method.
  • the flexible trap door is fastened to the access platform
  • Figure 6 shows a possible cross-directional reinforcement, which would be made up of round aluminium pipes with an inner diameter (D) of 5 mm, 1.5 mm (E 1) thick and 1.5x2 mm (E2xE3) flaps.
  • Figure 7 shows an example of configuration that would be made up of a silicon rubber body (1 ) with an inner polyester (6) mesh, 14 mm (E4) thick, with recesses of variable thickness (7) and transversely strengthened by the reinforcement (3), separated by a length (L) of 30 mm.
  • Figure 8 shows the end section of the trap door, finishing off in drillholes (8) to fasten it to the access platform with a diameter of 12 mm and a reinforcing flat bar (9).
  • Figure 9 shows the arrangement of elements on a 650mm-long (H), 550m-wide (A) trap door, displaying the typical profile of an access platform (2).

Abstract

L'invention concerne une trappe souple, à fermeture automatique, pour plates-formes d'accès, utilisable comme surface de travail, qui consiste en un corps en caoutchouc (1), fixé à la plate-forme d'accès (2), renforcé par un renforcement rigide transversal (3), comportant une bande (4) pour faciliter l'ouverture et un verrou (5) lorsque la trappe est transportée et assemblée. La fermeture est provoquée par la pression du caoutchouc. De plus, la fermeture est provoquée par un mécanisme à commande externe ou au moyen d'aimants.
