Definitions

  • the present invention relates to a fire barrier door, in particular for accessing shafts of lifts or the like.
  • lifts are constructed by means of a booth translating vertically inside a shaft that mutually connects multiple floors.
  • the booth is provided with a door, generally constructed with multiple sliding panels, whilst each floor is provided with a door that prevents access to the shaft in the absence of the booth at the floor.
  • the shaft housing the booth constitutes a connecting tunnel between the floors, particularly dangerous in case of fire because it is transformed into a sort of chimney and allows the flames to spread between contiguous floors.
  • so-called fire barrier doors are known, provided with sealing labyrinths that do not allow the shaft to interface directly with the floor.
  • known fire barrier doors comprise a frame mounted on the side that delimit the opening providing access to the lift shaft.
  • This frame is provided in particular with lateral jambs and with an upper cross member in which the door, generally constructed with sliding panels, is mounted.
  • the profile of the outer perimeter of the panels interacts with the profile of the jambs and of the cross member and generates seal means constituted by a labyrinth structure that prevents flames from spreading.
  • Known fire barrier doors have some drawbacks.
  • the supporting frame constructed with jambs and cross members requires masonry works to modify the profile of the opening providing access to the compartment and create a housing in which the frame itself can be stably fastened.
  • the purpose of the present invention is to eliminate the aforesaid drawbacks, making available a fire barrier door that does not need masonry works to position lateral jambs or horizontal cross elements, simplifying its installation especially in case of renovation works.
  • the fire barrier door of the present invention that is characterised by the content of the claims set out below and in particular in that it comprises a frame obtained by means of support sections mounted directly on the sides delimiting said opening and integrating a first portion defining the labyrinth structure.
  • Figure 2 shows a view of the door of Figure 1, sectioned according to a horizontal plane
  • Figure 3 shows a view of the door of Figure 1 , section according to a vertical plane; - Figures 4 and 5 show a possible embodiment variation of the door shown in Figure
  • Figure 6 shows an enlarged detail of Figure 1.
  • the reference number 1 globally indicates a fire barrier door.
  • the aforesaid door is interposed between a shaft 2 of a lift and one of the floors 3 connected by the lift itself.
  • the shaft and the floor are delimited by a wall 4.
  • connection between the shaft 2 and the floor 3 is achieved by means of an opening 5 obtained in the wall 4 and of substantially rectangular shape delimited by vertical sides and horizontal sides.
  • the door 1 is therefore housed between the shaft 2 and the floor 3 in proximity to the opening 5.
  • a frame 6 is fastened whereon two panels 7, able to slid along opposite directions, are mounted.
  • the direction of translation of the two panels is horizontal and the two panels are movable between an open position, in which it is possible to access the compartment 2 and in particular the booth of the lift present at the floor, and a closed position illustrated in
  • the labyrinth structure is obtained by means of a first portion 8a associated to the frame 6 and a second portion 8b associated to the outer profile of the door.
  • the frame 6 is originally constructed by means of support section bars 9 mounted directly on the vertical sides and on the upper horizontal side that delimit the opening providing access to the shaft.
  • the installation of the support section bars 9 is accomplished without masonry works, by means of simple fastening with threaded elements 10.
  • the supporting section bars 9 comprise a first folded plate on each side, provided with the first portion 8a having substantially "C" shaped section.
  • the "C” shaped section is so positioned as to exhibit a first and a second segment, respectively substantially perpendicular and parallel to the direction of sliding of the corresponding panel.
  • the first and the second segment make up the first portion 8a of the labyrinth structure and interact with the outer profile of the corresponding panel.
  • This outer profile complements the second portion 8b of the labyrinth structure because it has, in turn, a substantially "C" shaped section whose segment parallel to the direction of sliding of the panel is superposed to the second segment of the respective lateral profile, when the door is in the closed position.
  • the supporting section bars comprise a second folded sheet place positioned horizontally on the upper side of the opening.
  • This horizontal section bar also comprises a portion having substantially "C" shaped section that constitutes the first portion 8a of the labyrinth structure.
  • a sustaining bracket 11 can be provided, having a first end mounted directly on the sides delimiting the opening for accessing the shaft and a second end connected to the first portion of the labyrinth structure.
  • Figures 4 and 5 show two possible embodiments of the fire barrier door of the present invention.
  • the supporting section bars are mounted in such a way as to project internally to the opening providing access to the compartment.
  • the supporting section bars are mounted externally to the perimeter of the opening providing access to the shaft.

Abstract

La présente invention concerne une porte coupe-feu (1) permettant en particulier l'accès à des cages d'ascenseurs (2) ou analogues, laquelle porte comprend : un châssis (6) monté sur les côtés qui délimite une ouverture permettant d'accéder (5) à la cage (2) ; et au moins un panneau (7) monté coulissant par rapport au châssis (6) et pouvant se déplacer entre une position ouverte et une position fermée. L'invention comprend en outre au moins une structure de labyrinthe (8) produite, lorsque la porte (1) se trouve en position fermée, par l'interaction entre une première partie (8a) qui forme partie intégrante du châssis (6) et une seconde partie (8b) qui forme partie intégrante du profil extérieur de la porte. Le châssis (6) est formé au moyen de profilés en acier de support (9) montés directement sur les côtés délimitant ladite ouverture (5), qui viennent compléter la première partie (8a) afin de définir la structure de labyrinthe (8).
