Definitions

  • the invention relates to a security device for buildings, and more specifically for buildings comprising at least one wall, for example a facade, at least partially glazed, essentially consisting of a rigid structure, preferably metallic, to which one or generally several glass panels are associated, so that the structure is not visible.
  • a safety device according to the invention will advantageously be provided for each of the front glass panels or other wall of the building.
  • the rigid, generally metallic, structure of the building defines at least one frame on which a glazed panel is rigidly associated by means of association by simple bonding, without glazing beads, with interposition of seals and fixing between the interior surface of the panel and structure.
  • These means of association of the panel with the chassis of the structure may be faulty. For example, they can deteriorate after a certain time, in particular under the effect of bad weather. In this case, the glass panel detaches from the structure and falls. However, such a fall can cause considerable damage to objects or people located at the foot of the building.
  • a safety device for a building with a glass wall and / or facade comprising at least one glazed panel is already known from European patent application 0 251 834, each glazed panel being able to consist of one or more panes associated with the frame of the structure.
  • rigid of the building by rigid association means normally permanently active the safety device comprising at least one holding part in place in the vicinity of the chassis and / or destruction of the panel glazing, this part cooperating with at least a portion of the periphery of the outer glass of the panel with a view to maintaining and / or destroying it in the event of failure of the means of association of the panes constituting the glazing of the panel to each other and / or in the event of failure of the means of association of the panel with the frame, with the aim of preventing the panel or part of its glazing from falling in one piece.
  • the panel comes to detach from the structure, it is either maintained, or, if the maintenance is not possible, broken and reduced to pieces before falling.
  • the consequences of the fall of the panel are then benign because the multitude of small pieces resulting from the breakage of the panel is much less devastating than one-piece glazing.
  • glazing associated by bonding to the frame of a rigid structure must be capable of being able to move slightly relative to the rigid structure, in particular under the effect of wind, or thermal phenomena. For this reason, it is not generally possible to rigidly and directly fix such a safety piece to the chassis of the rigid structure. Indeed, in such a case, the part could not move with the glazing, and would be likely to destroy this glazing while no problem has appeared in the various association joints.
  • it is preferable or even essential that such safety parts form an integral part of the panel and be rigidly associated with it.
  • European patent application 0 251 834 describes a possibility of fixing the security parts to a panel with multiple glazing, thanks to a protuberance of the part which comes to penetrate the peripheral joint of the panel between the interior glass and the exterior glass.
  • the invention therefore aims to remedy these drawbacks and relates to a safety device intended for a glazed panel consisting of a single pane, which can be rigidly and securely associated with this pane, in a simple and economical manner.
  • Another object of the invention is to provide such a safety device which is compatible with most of the methods of fixing the panel to the structure, that is to say which does not harm the integrity of the joints of sealing and association of the panel with the structure.
  • Another object of the invention is to propose such a safety device which can fulfill the same functions and with the same efficiency for simple glazing as those known for multiple glazing, in particular from European patent application 0 251 834.
  • the invention aims to propose a safety device for exterior glazing bonded to a single window, which ensures the maintenance in place of the glazed panel in the event of failure of the means of fixing the panel to the structure, or which, in the case where the glazing is made of tempered glass, ensures breakage of this glazing if its maintenance in the vicinity of the structure is not possible; this safety device being inactive, subject to any constraint, not wearing out, not working and therefore not affecting the life of the glazing, when the fixing means are normally active and in good condition; this safety device returning to operation only when the fixing means have suffered unacceptable deterioration; this safety device being invisible from the outside; this safety device can be mounted integral with each glazed panel so that the panels arrive on the site provided with such safety devices.
  • the invention provides an invisible security device for a building with a glass wall and / or facade comprising at least one glass panel, each glass panel consisting of a single window associated with the chassis of the rigid structure of the building by means of association normally permanently active, the safety device comprising at least one piece for holding in place in the vicinity of the frame and / or for destroying the glazing of the panel in the event of failure of the means for associating the panel with the frame, a such a part cooperating with a portion of the periphery of the glass, characterized in that each part comprises a tab for associating this part with the internal face of the glass, this tab extending at least substantially parallel to and facing d 'a peripheral portion of this internal face so that it can be associated with it by bonding or equivalent.
  • a security part according to the invention consists of a section portion and, according to another characteristic of the invention, seen in cross section perpendicular to the corresponding edge of the window, a part of the security device is made, of outside towards inside, of an external branch cooperating with a portion of the external face of the window; an intermediate branch cooperating with the frame by means of suitable elements, and extending at least substantially perpendicular to the plane P of the window pane along a portion of the edge of this pane; and of the association tab which extends at least substantially parallel to the plane P of the glass in the direction of the central part of the glass, from the internal end of the intermediate branch, the part having substantially the shape of 'a U or a pseudo-U so that it can fit together by wedging on the glass.
  • the invention also relates to a glazed facade panel with a single pane characterized in that it comprises a safety device according to the invention consisting of at least one part which is associated with it by bonding or equivalent on a portion of the face internal of the glass.
  • the invention relates to a method of associating a safety device according to the invention with a glazed panel consisting of a single pane, characterized in that a seal bottom is placed, in particular in polyurethane foam or other, locally at the extreme periphery of the internal face of the glass, at the location where a part must be fixed, the part is then fitted by wedging the bottom of the joint between the tab and the glass, then depositing an adhesive seal, in particular silicone, overlapping towards the inside of the seal bottom, between the free end of the tab and the glass.
  • the invention relates to an invisible security device for a building with a glass wall and / or facade.
  • This wall or facade essentially consists of a rigid structure, generally metallic, and a plurality of glazed panels 2.
  • This wall or facade separates an interior space 21 from an exterior space 22.
  • the structure 1 defines a frame 3 on which the panel 2 is associated by association means 4 which are bonding means without glazing beads, and comprise one or more association and / or sealing joints 4, constituted for example silicone with high elasticity modulus.
  • association means 4 which are bonding means without glazing beads, and comprise one or more association and / or sealing joints 4, constituted for example silicone with high elasticity modulus.
  • the different frames 3 corresponding to each of the panels 2 of the structure 1 are associated with each other in a known manner by means of association and sealing consisting for example of a silicone seal and a bottom seal.
  • the seals are for example seals made of polymer, in particular silicone.
  • the invention relates to a safety device according to the invention for a building with a glass wall and / or facade comprising at least one glass panel 2, each glazed panel 2 consisting of a single window 5 associated with the frame 3 of the rigid structure 1 of the building by means 4 of association normally active permanently.
  • the safety device according to the invention comprises at least one piece 6 for holding in place in the vicinity of the frame 3 and / or for destroying the glazing of the panel 2 in the event of failure of the means 4 for associating the panel 2 with the frame 3.
  • Such a part 6 consists of a section portion, and cooperates with at least one portion 7 of the periphery of the external face 8 of the window 5.
  • such a part is generally designed in such a way that it can fulfill two successive functions: a first function of holding the window 5 of the panel 2 in place in the event of a slight, progressive or partial failure of the means 4 for associating the panel 2 to the frame 3, and, in the case where the glazing is made of tempered glass or equivalent, a second function of destruction of the window 5 of the panel 2 in the event of a sudden complete failure of the means 4 for associating the panel 2 with the frame 3 and when the fall of this window 5 is inevitable.
  • the part 6 makes it possible to cause the window 5 to break before it falls, in order to prevent this window 5 from falling in one piece.
  • each piece 6 has a tab 11 for associating this piece 6 with the internal face 9 of the window 5, this tab 11 extending at least substantially parallel to and facing a peripheral portion 10 of this internal face 9 of the window 5, so that it can be associated with it by bonding or the like.
  • a part 6 does not extend longitudinally over an entire edge of the window 5, but only over a peripheral portion of an edge or of a corner of the window 5.
  • a profiled part 6 consists of an outer branch 13 cooperating with a portion 7 of the outer face 8 of the window 5; an intermediate branch 14 cooperating with the chassis 3 by means of suitable elements 15, 16, this intermediate branch 14 extending at least substantially perpendicular to the plane P of the window 5 along a portion of the edge 12 of this window 5; and paw 11 of asso ciation which extends at least substantially parallel to the plane P of the window 5 in the direction of the central part of this window 5 from the inner end 17 of the intermediate branch 14.
  • the profiled part 6 therefore has, in cross section transverse, substantially the shape of a U, or of a pseudo-U depending on the shape given to the external branch, so that it can fit together by jamming on the window 5 by covering a corresponding portion of the edge 12.
  • the intermediate branch 14 has a length (in the perpendicular direction of the plane P of the window 5) sufficient to allow the fitting of the part 6 on the edge 12 of the window 5. According to the invention, the intermediate branch 14 has however a length such that it allows one or more suitable seals 18, 19 and / or 20 to be interposed between the tab 11 and the internal face 9 facing the window 5 and / or between the external branch 13 and the external face 8 next to the window 5.
  • the intermediate branch 14 has a length such that the total thickness formed by the seals 18, 19 interposed the tab 11, inwards 21 from the window 5, is less than the thickness according to the same direction of the means 4 for associating the window 5 with the frame 3, that is to say is less than the distance separating the internal face 9 of the window 5 from the facing frame 3.
  • this length of the intermediate branch 14 is such that a clearance 23 is left between the tab 11 and the frame 3 when the window pane 5 is rigidly associated with this frame 3.
  • the clearance 23 is provided to be the same order of magnitude as the clearance 32 which is also provided between the intermediate branch 14 and the chassis 3.
  • the clearance 23 is in particular at least 2 mm.
  • a part 6 is therefore not directly associated with the chassis 3, but on the contrary constitutes, thanks to the clearance 23, means for detecting an inadvertent transverse movement of the window 5 perpendicular to its plane.
  • the detection by the part 6 takes place by contact of the tab 11 of this part 6 with the chassis after clearance of the clearance 23, the chassis 3 forming a transverse stop for this tab 11.
  • a part 6 is formed from a metal profile, in particular aluminum, extending along a portion of the edge 12 of the window 5 in the vicinity of a corner 24 of the window 5.
  • the length of this metal profile is for example between 1 and 20 cm, in particular of the order of 10 cm.
  • the external branch 13 is inclined towards the outside 22 in order to be able to cooperate with a portion 7 of the external face 8 of the window 5 which is bevelled with the same inclination.
  • the glazing of a panel 2 is sometimes made of safety glass of the thermally pre-stressed tempered type or equivalent, and, this bevelled portion 7 of the external face 8 of the window 5 being weakened, the part 6 is capable of producing a chipping at this point of the glass 5 in the event of a sudden failure of the means 4 for associating the glass 5 with the frame 3. In this way, the glass 5 breaks into a multitude of small pieces when the part 6 produces a chipping on the portion 7 of its external face 8.
  • the part 6 only achieves this chipping, and therefore fulfills its destruction function, only from a certain transverse displacement (perpendicular to the plane P of the panel 2) determined from this panel 2.
  • destruction is avoided untimely glazing in the event of sudden movement of the panel 2 without effective deterioration of the means 4 for associating the panel 2 with the frame 3, for example in the event of displacement due to the action of the wind.

  • the light 16 has larger dimensions than the lug 15 so that the cooperation between the lug 15 and the light 16 is done with a certain clearance 33, in particular in all directions in order to avoid inadvertent activation of the function of maintaining or destroying the part 6, or the stresses which are too great in the event of slight movement of the window 5 no accompanied by deterioration or failure of the means 4 for associating the window 5 with the frame 3.
  • the part 6 does not come into operation until a certain movement perpendicular to the plane P of the window 5, movement which is dimensioned to necessarily correspond to a deterioration of the means 4 of association of this window 5 to the frame 3.
