Definitions

  • the present invention relates to devices for traversing walls of premises making it possible to pass through said walls by electric cables or flexible pipes conducting fluid, temporary.
  • fire protection doors or flame protection doors are generally installed.
  • FR-A-2.158.599 forming the preamble of claim 1, describes a fire-stoppering device for pneumatic transport circuits comprising at the crossing locations of floors, ceilings and the like, at least one heat-resistant sleeve ensuring the connection of the circulation tubes of the pneumatic circuit, said connection sleeve being provided with a closure member retained in the open position by a fusible element and biased in the closed position by an elastic return member.
  • the invention aims to remedy the drawbacks of known solutions by creating a device for passing temporary supply cables or pipes through a partition between two zones of an installation, which meets the criteria for partitioning between zones, which is free of risks of deterioration of the routing of cables or conduits and which allows the maintenance of the doors of connection between zones in closed position.
  • a fire protection device for ensuring passage through a partition wall between two zones of an installation, cables and / or flexible conduits for supplying electrical or other energy, comprising, provided in the wall, a passage opening out on the two faces of the latter and in which are arranged two metal half-sleeves, each provided at its end external to the wall, with a closing flap, articulated on the corresponding half-sleeve, characterized in that the two metal half-sleeves are separated by an interval, preventing the formation of a thermal bridge, and in that the closing flap of each sheath is a closing flap by gravity, provided with a plug in composite fire-resistant product.
  • the fire-rated feedthrough device also known as a wafer stop hopper shown in Fig. 1, is placed in a solid M wall of concrete.
  • a shutter or tape 5.6 connected to the corresponding half-sleeve by a pin 7.8 protected by an anti-corrosion treatment and arranged to so that the flap or tape 5.6 can be applied to its seat 9, 10 formed by the end of the corresponding half-sheath, under the effect of its own weight.
  • Each of the flaps 5,6 has fixed on its face opposite the corresponding half-sheath 2,3, a plug 11,12 of intumescent fire-resistant composite product fixed to the flap by means of a corrosion-resistant metal screw and poor thermal conductor such as stainless steel (not shown) with possibly additional bonding in order to increase the adhesion of the plug to the flap and avoid mechanical fatigue of the assembly linked to the openings and closings.
  • a corrosion-resistant metal screw and poor thermal conductor such as stainless steel (not shown) with possibly additional bonding in order to increase the adhesion of the plug to the flap and avoid mechanical fatigue of the assembly linked to the openings and closings.
  • the caps 11, 12 made of composite material are replaceable parts.
  • the half-sleeves 2, 3 are placed in the passage 1 and glued to the wall of the passage 1 by means of an appropriate adhesive such as an epoxy adhesive.
  • the spacing or interval 4 between the half-sleeves is for example from 1 to 3 cm to avoid thermal bridges.
  • the installation technique is the same as that which has just been described for a concrete wall.
  • FIG. 2 and 3 show two successive phases of installation of the device according to the invention in a hollow rubble wall.
  • a formwork tube 17 made of polyvinyl chloride for example is first introduced.
  • a mortar grout 18 is injected into the cavity or cavities or cells 16.
  • the shuttering tube 17 is removed and the passage 15 is then ready to receive a device according to the invention according to the same laying technique as that described with reference to Fig.1.
  • fire protection devices according to the invention in prefabricated form to equip for example new constructions or even existing concrete block partitions.
  • the device is produced by mounting in a concrete block 20 having the dimensions of a standard concrete block which it is intended to replace in a partition and provided with a passage 21 for receiving the half-sleeves. 2 and 3.
  • FIG.6 there is shown a crossing device according to the invention mounted in a concrete wall in two parts P1, P2 separated by an expansion joint J.
  • a borehole 25 is made in the wall, which is lined with a sheath 26, for example made of fiber cement, of dimensions suitable for the half-sheaths 2 and 3 of the crossing device.
  • the role of the sleeve 26 is to prevent deterioration of the expansion joint J.
  • Fig.7 there is partially shown the crossing device according to the invention in which cables C are engaged which rest on the half-sleeves 2 and 3 of the device and which slightly raise the shutter flaps such as flap 5 equipped of its plug 11 of fire-resistant composite material.
  • the device shown in Fig. 7 is in a normal state in the absence of fire.
  • Fig.8 the same device is shown in Fig.7, but after a fire has started and the plug 11 made of fire-resistant composite material has closed the end of the cavity of the half-sheath 2 by swelling under the effect of heat caused by a fire.
  • the other plug fitted to the shutter of the half-sheath 3 has closed the other end of the passage thus formed, so that any propagation of fire through the crossing device is thus prohibited .
  • FIG. 9 an embodiment of a half-sheath of the crossing device according to the invention is shown, for example the half-sheath 3 equipped with its shutter 6.
  • the half-sheath 3 has at its upper part a yoke 28 whose branches are fixed to the half-sheath 3 by welding and in which the axis is mounted horizontal 8 of articulation of the shutter 6 on the half-sheath 3.
  • the flap 6 has a straight side 29 on which are fixed lugs 30 for connection with the axis 8.
  • the flap At its end opposite to the straight side 29, the flap comprises a fork 31 cooperating with a fitting 32 provided with an eyelet 33, fixed to the half-sleeve 3 in a position roughly diametrically opposite to the yoke 28 and thus allowing locking the flap 6 in the closed position against the end of the half-sheath 3 for example using a padlock not shown.
  • the fire-resistant intumescent composite material plug 12 is fixed to the flap 6 in a position coaxial with the half-sheath 3, for example by means of a screw 34 made of stainless steel.
  • the notch 36 is placed near the position of the conduits (C) for temporary connection.
  • a notch 36 is provided in each plate 35, it is possible to provide several notches. Furthermore, the expansion of the fire-resistant product can be guided by a guide with a shape different from that of the plate 35.
  • the half-sleeve shown in side view in Fig.10 corresponds to the half-sleeve of Fig.9 and has one end 10 perpendicular to its axis, so that when closed, the shutter occupies a vertical position.
  • the half-sleeve 37 represented in FIG. 11 differs from that of FIG. 10, in that its end 38 forming a seat for the flap 39, is inclined relative to the axis of the half-sleeve, so that in the closed position, the flap 39 occupies an oblique position, which improves the application of the flap 39 by its own weight against its seat 38.
  • the half-sleeve 37 being of circular section, its inclined end 38 is of elliptical shape and the shutter 39 must therefore have a corresponding shape.
  • Fig.12 there is shown a crossing device according to the invention formed by two half-sleeves 40 and 41 with inclined seats of the type described with reference to Fig.11.
  • a biological protection plug 42 connected to one of the shutter flaps 40 by a cable 43.
  • the plug 42 has a length which is a function of the effectiveness of the protection sought and the thickness of the wall equipped with the crossing device according to the invention.
  • the crossing device according to the invention which has just been described was subjected to fire tests which proved to be conclusive, because the temperature rises observed after two hours remained within the admissible limits.
  • the crossing device according to the invention is relatively simple to install and is suitable for the most diverse types of partitions.
  • the half-sleeves of the device are advantageously made of galvanized sheet metal or painted, in a decontaminable system in order to limit their maintenance.
  • the installation of the device does not require any special qualification.
