Definitions

  • the present invention relates to a fire wall, in particular a fire wall that can easily be integrated into a steel frame building, as well as components of a fire wall.
  • a fire wall is intended to stop or delay the advance of a fire in a building. According to French regulations currently in force, it must resist, in the laboratory, for a given time (generally 4 hours) under the conditions of a conventional fire and be impervious to hot gases. In addition, the temperature on the surface opposite the fire must not exceed 140 ° C on average and 180 ° C at an extreme point. In principle, the fire wall must extend beyond the roof and, in the case of a metal frame building, the deformation or collapse of the steel frame on the fire side must not result in the failure of the fire. firewall.
  • the first type is a firewall comprising a supporting structure of thin steel profiles coated with gypsum board and filled with mineral wool.
  • This type of firewall presents problems when it comes to ensuring its durability in case of deformation or collapse of the steel frame on the side of the fire.
  • the second type is a firewall that is molded between two independent load-bearing structures and is connected to them by fusible ties that will melt on the side of the wall exposed to the fire and remain intact on the opposite side of the fire. Therefore, if the load-bearing structure on the firewall side exposed to the fire collapses, this will not ruin the firewall. The latter is still supported by the fusible links, which attach it to the supporting structure located on the side of the firewall that is not exposed to fire.
  • a fire wall of the second type is marketed by the company YTONG under the name "fire wall with split metal structure.” It is a wall built with cellular concrete cladding slabs erected between split columns, whose spacing is only slightly larger than the thickness of the cladding slabs. All vertical joints between the cladding slabs are between the posts and are filled with rockwool. Horizontal joints include a tongue and groove system and must be fully bonded with a mortar.
  • YTONG fusible fasteners consist of fusing plates, which are fastened with nails either on the visible faces of the cladding slabs or on the horizontal contact surfaces between two cladding slabs, and which support behind the wings polls.
  • a major disadvantage of the split metal structure YTONG system is that the firewall must be erected before closing the building, as the cladding slabs must engage at the top between the split posts.
  • Another disadvantage of the split metal structure YTONG system is that the integration of large sliding fire doors in this type of firewall is almost impossible.
  • cladding slabs of cellular concrete are generally not allowed in agri-food buildings, given the constraints of hygiene.
  • a fire wall including the features of the preamble of claim 1 is described in the document DE 100 40 699 .
  • a first object of the present invention is to make easier and more flexible the fire compartmentalisation of metal constructions. According to the invention, this objective is achieved by a fire wall according to claim 1.
  • a second object of the present invention is to provide a better anchoring system for firewalls.
  • Another object of the present invention is to provide fire resistant panels with a very compact sandwich structure, which make it possible to construct walls having a very high fire resistance (for example of the order of 4 hours and more).
  • Yet another object of the present invention is to provide a joint between two fire resistant panels which not only guarantees a solid assembly of the panels and excellent flame, smoke and hot gas tightness, but which also allows for easy replacement of a damaged panel in the wall.
  • the present invention provides a fire wall comprising: a wall constructed using fire resistant panels; an independent metallic support structure on each side of the wall; an anchoring system for each of the two supporting structures, with anchoring points between the wall and the supporting structure; and at least one fire detection means associated with each anchoring system so as to cause, in the event of a fire, a rupture of said anchoring points on the side of the wall which is exposed to the fire.
  • the spacing between the two supporting structures is equal to at least twice the thickness of a fire-resistant panel, the wall being arranged in the middle between the two supporting structures. Such spacing between the two carrier structures provides multiple benefits.
  • An anchor located at a certain height above the ground is designed to allow an increase in the spacing between the wall and the supporting structure of the order of one to several centimeters before opposing this increase by resuming a pulling effort.
  • Such an anchor point does not exert a tensile force on the wall, when one of the two load-bearing structures is subjected, under the load of the wind, to a bending which tends to increase the spacing between the bearing structure and the wall.
  • a preferred embodiment of an anchor comprises: a first horizontal attachment arm attached to one of the two supporting structures and provided with a first through hole for a pin; a second horizontal attachment arm attached to the wall and provided with a second through hole for a pin, the two holes being vertically superimposed.
  • a pin with a vertical axis is housed in the two holes and serves for the transmission of forces between the two attachment points. During this transmission of forces, the pin is essentially stressed in shear.
  • One of the two vertically superposed holes is advantageously an oblong hole.
  • one can adjust the point of attachment so as to tolerate an increase in the spacing between the wall and the supporting structure of the order of a few centimeters, before the pin is stressed in shear.
  • an oblong hole also allows easier mounting of the anchor points, because it compensates for unevenness in the spacing between the wall and the carrier structure.
  • the pin can also be arranged in the oblong hole so as to transmit a compression on the horizontal attachment arm fixed to the wall with low axial play and to transmit a traction on the latter with a much greater axial play.
  • the anchor point also has a fulcrum function between the wall and the supporting structure that connects.
  • an anchor in a preferred embodiment, includes a fuse element holding the pin in place in both holes. It will be appreciated that this fuse element must not participate in the transmission of a tensile force or compression by the anchor point, which naturally facilitates its dimensioning.
  • This anchor then advantageously comprises a spring element, which is associated with the pin so as to drive axially from its housing when the fuse element breaks, thus releasing the first of the second attachment arm.
  • the spring exerts a constant and well-defined force on the fuse element, which ensures a more accurate melting temperature.
  • the anchoring system may also comprise a system of rods adapted to occupy a first position, in which it holds in place the pins of at least two anchoring points in their respective holes, and a second position in which it releases these pins.
  • Actuating means are then associated with this system of rods to bring it from its first position to its second position.
  • actuating means are advantageously slaved to a triggering means.
  • the latter is for example a fuse element, another type of fire detector, a fire extinguishing system (for example a sprinkler system) or manual triggering means, which can be actuated by firefighters.
  • the fire-resistant panels are preferably lightweight sandwich-structure panels which are provided with an outer facing formed of steel sheets.
  • the present invention also relates to a new type of very compact sandwich panels, which make it possible to construct walls having a very high fire resistance (for example of the order of 4 hours and more).
  • a fire resistant panel has a central core comprising at least one gypsum board and a thermal insulation layer based on cellular glass adhered to each face of the central core.
  • venting means are arranged between the central core and each thermal insulation layer, so as to evacuate the steam formed during the heating of the plaster of the central core to the joints between the panels. In this way, a controlled evacuation of the water vapor formed during the heating of the plaster of the central core is avoided, and it is avoided to explode the sandwich panel under the effect of an excessive increase in pressure.
  • the thermal insulation layers are preferably fixed by means of a discontinuous bonding on the central core, so that there remain gaps between the bonded regions. These voids then form venting means able to evacuate the steam.
  • steel sheets are fixed by surface bonding to the thermal insulation layers to form an outer face of the panel.
  • This steel sheet forming the outer facing is preferably a thin sheet of carbon steel coated with an alloy composed of aluminum and zinc.
  • a preferred alloy comprises for example between 53% and 57% of aluminum, 41% and 46% of zinc and 1% and 2% of silicon.
  • the steel sheet forming the siding normally has a thickness of 0.6 to 1.3 mm. It will be noted that the aforementioned alloy significantly and unexpectedly increases the fire resistance of the sandwich panels. We think we can explain this surprising phenomenon as follows.
  • the central core of the panel advantageously comprises a load-bearing panel based on fiber-reinforced cement; and on each side of the carrier panel, a gypsum board glued to the carrier panel.
  • the carrier panel has a deformation under heat lower than the drywall.
  • This load-bearing panel serves as a structural support for plasterboard and is intended to keep them in place as long as possible in case of fire.
  • a panel according to the invention advantageously comprises a frame formed with mineral plates bonded to the edges of the sandwich structure.
  • This frame is preferably formed with plates based on fiber reinforced cement.
  • the external cladding formed of steel sheets forms low rims along said frame, so as to staple the frame, without constituting a thermal bridge. It will be appreciated that such a frame substantially enhances the mechanical stability of the edges of the panel. In case of fire, it therefore contributes to a better tightness to flames, fumes and hot gases at the joints between the panels.
  • the frame advantageously comprises holes for evacuating the steam formed during the heating of the plaster of the central core through the joints between the panels.
  • the present invention also presents a new type of seals for the assembly of fireproof panels in a wall.
  • a joint between two panels is formed by a key-fitting side of a first plate which bears on a side without a connecting key of a second plate.
  • This joint is closed on each side by an omega profile forming a central channel flanked by two flanges.
  • the center channel is secured with lag bolts on the fitting key.
  • the soles are fixed using self-drilling screws on the outer face formed of steel sheets.
  • a plate is attached to the omega profile to cover the central channel. It is advantageously a carbon steel plate coated with an alloy composed of aluminum and zinc, as described above.
  • An intumescent strip is preferably attached to the steel plate in the central channel of the omega profile.
  • This method of joint construction not only guarantees a solid assembly of the panels and an excellent seal of the joints to flames, fumes and hot gases. It also allows easy replacement of a damaged panel in the wall. After disassembling omega dishes and profiles, you can simply remove a damaged panel from the wall and replace it with a new panel.
  • the fire resistant panels are advantageously rectangular panels with a length to height ratio of 2 to 1 and which preferably have a length of less than 3 m.
  • the Fig. 1 shows a section through a metal frame building at a fire wall 10 comprising a wall 12 constructed using fire resistant panels 14.
  • the metal frame of the firewall building is divided into two structurally independent metal supporting structures 16 and 16 '. This means that there are no structural links between the left bearing structure 16 and the right bearing structure 16 '. Therefore, a collapse of the left carrier structure 16 will not result in the ruin of the right carrier structure 16 'and vice versa.
  • Each of the two supporting structures 16, 16 ' comprises vertical posts 18, 18' supporting beams 20, 20 'carrying a roof 22, 22'. In fact, it is two independent roofs 22, 22 ', which are separated by an overflow 24 of the wall 12 on the roof and connected to this protrusion 24 sealingly.
  • These bearing structures 16, 16 'could also comprise beams carrying an intermediate floor (not shown) on one or both sides of the wall 12.
  • each supporting structure 16, 16' may further comprise elements of vertical and horizontal bracing (not visible) and rails 26, 26 ', that is to say horizontal sections fixed to the vertical posts 18, 18' of a bearing structure 16, 16 'and serving in particular for anchoring of the wall 12 (see eg. Fig. 3 ).
  • anchoring system with anchoring points 28, 28' between said wall and the respective bearing structure 16, 16 '.
  • anchor points 28, 28 ' are slaved to a fire detection means, which is capable of provoking, in the event of a fire, a break in the anchoring points on the side. wall 12 which is exposed to fire.
  • a fire detection means which is capable of provoking, in the event of a fire, a break in the anchoring points on the side. wall 12 which is exposed to fire.
  • the wall 12 is separated from the supporting structure 16, 16 'of the fire side, but is still supported by the bearing structure 16, 16' of the side opposite to the fire. Therefore, the carrier structure 16, 16 'exposed to the fire can collapse without causing the ruin of the wall 12.
  • This gap “D” is normally equal to two to three times the thickness "E" of a fire-resistant panel (that is to say it is preferably: 2 ⁇ D / E ⁇ 3). On the Fig. 1 this "D / E” ratio is for example equal to 2.5. In absolute figures, the distance “D” preferably measures between 30 cm and 60 cm.
  • This gap "D" rather important between the two supporting structures 16, 16 ' provides multiple advantages. It allows for example to easily erect the wall 12 when the bearing structures 16, 16 'are already in place. This is particularly interesting when large industrial halls are being built and it is not yet known what fire compartmentalization should be planned. With a system according to the present invention, it is then sufficient to divide the metal framework of the hall into several independent supporting structures with a spacing "D" between two adjacent supporting structures which is equal to at least twice the thickness "E" d a fire-resistant panel, to be able to easily erect, as needed and at any time, a wall 12 with fire-resistant panels 14 between two independent bearing structures, to form a fire compartment.
  • the anchoring point 28 mainly comprises two brackets 34, 36, a pin 38, a fuse element 40 and a spring 42.
  • the first bracket 34 is fixed to the post 18 and comprises a first horizontal attachment arm 44 which extends in the direction of the wall 12.

  • the connection between the bracket 52 and the fuse element 40 and the connection between the fuse element 40 and the pin 38 are preferably cylindrical joints 54, 56, so as to prevent the pin 38 from urging the element fuse 40 in flexion, when the post 18 moves towards or away from the wall 12.
  • the spring 42 bears with one end on a shoulder 58 of the pin 38, and with the other end on the underside of the second arm 46. It is pre-compressed so as to exert on the fuse element 40 a predetermined tensile force.
  • the manufacturer of the fuse element 40 generally indicates a minimum tensile stress and a maximum tensile force for which it ensures the rupture of the fuse element 40 at its nominal temperature.
  • the prestressed spring 42 also produces an elastic ejection force of the pin 38, when the fuse element 40 breaks in the event of a fire, thus reducing the risk that the pin 38 remains stuck in the through holes 48, 50.
  • the fusible element 40 typically a nominal breaking temperature between 120 ° C and 200 ° C and is for example dimensioned for a minimum tensile force of 1 kg and maximum of 10 kg. It is also possible to work with fusible elements 40 at different breaking temperatures. The fusible elements 40 of the anchoring points located closer to the ground will then have a lower breaking temperature than the fusible elements 40 of the anchor points located closer to the roof 22, 22 '.
