Definitions

  • the present invention relates to a shutter device as defined in the preamble of claim 1.
  • a shutter device as defined in the preamble of claim 1.
  • Such a device is known from the document EP-A-1323887 or document EP-A-1035297 .
  • Said device is intended to close one, and preferably each, of the two lateral ends of a box-tunnel, of U-shaped cross-section returned, for rolling shutter, and a tunnel-box of the aforementioned type, intended to be integrated into the lintel of a bay of a construction and the surrounding masonry, and to house a shutter, and which is equipped with two shutter devices according to the invention.
  • tunnel caissons each of which is generally formed by a shell molded of synthetic material, for example with a honeycomb structure, and consists of a vault supported by two longitudinal walls, the lower edge of each is integral with a metal profile, usually of aluminum, in the form of a rail, so that the tunnel box has a U-shaped cross-section, defining a tunnel-shaped recess, the lower part of which is open to allow to house a shutter.
  • each tunnel box is closed, at each of its lateral ends, by a shutter device comprising mainly a cheek and a heel perpendicular to the cheek and projecting on the internal face of the cheek, at its base, in order to be directed inward of the corresponding lateral end of the caisson-tunnel, when the shutter device is placed in the closed position of this lateral end.
  • Such a tunnel caisson is intended to be integrated, either during construction of a building, or after this construction, at the lintel of a bay, such as a window or door, provided in this construction, and therefore integrated in the surrounding masonry, as shown on the figure 1 and described with reference to this figure in the first aforementioned patent which will be referred to for further details on this subject.
  • the cheek of the latter fits at least partially into said lateral end, while the corresponding heel is inserted between the two metal rails, which serve as stiffeners, and one of which, which is fixed along the lower edge of that of the two longitudinal walls of the tunnel box which is turned towards the outside of the building, ensures the outer edge of the plastering.
  • a tunnel-box is generally integrated into the lintel of a bay being placed so that the outer side wall (facing the outside of the building) is aligned with the outside of the bare wall in which the bay to be equipped with a tunnel box with shutter is provided.
  • this longitudinal wall is, like the surrounding rough wall, covered with a plaster.
  • this metal rail usually aluminum, which ensures the outer edge of the plaster at the upper edge of the bay, is subject to temperature variations, because of its exposed position against the building facade.
  • the temperature at the front of a building can oscillate between -20 ° C in winter and + 50 ° C in summer, so that this rail can undergo a difference of about 70 ° C between these maximum and minimum temperatures.
  • the metal or metal alloy of this rail for example aluminum, has a physical property which, in this application, is troublesome, but inevitable, namely a coefficient of thermal expansion which is, for aluminum, 23 ⁇ per meter and per degree centigrade.
  • the elongate metal section constituting this rail develops mechanical stresses in the masonry, when it is extended by thermal expansion, while being supported and blocked on the shutter devices closing the lateral ends of the tunnel box, and related to the surrounding masonry by a binder, such as a grout of concrete or cement, filling the void left to the assembly, between the outer face of this shutter device and the masonry elements, such as bricks and blocks, facing in the surrounding masonry.
  • a binder such as a grout of concrete or cement
  • the problem underlying the invention is to overcome this disadvantage, and to propose a shutter device, of the type presented above, which is better suited to the various requirements of the practice than those of the state of the art, in particular according to the two aforementioned patents.
  • the invention proposes a shutter device, of the type presented above, and which is characterized in that the cheek has, in at least one of the two sides of its base which are facing the lateral ends of the rails, at a same lateral end of the tunnel-box, a recess forming a reservation for the thermal expansion of a tunnel-box rail, and capable of absorbing the elongation of said rail because of the temperature variations that he suffers in service.
  • Such a reservation has the advantage that it accepts elongations and displacements of the corresponding end of a rail without tensioning the outer wall of the tunnel-box along the lower edge of which this rail is fixed.
  • this rail usually aluminum
  • the rail is cut to the same length as the tunnel box, for example using a circular saw. It is, of course, possible to shorten each of the two rails at each of its two ends, by performing, for each end concerned, a resumption of cutting operation at both ends of the tunnel box.
  • the present invention proposes a simple and economical alternative by creating, in the cheek, at least one cavity to absorb the elongation of the aluminum rail due to its thermal expansion, elongation which is far from being negligible since the subwoofers can have a maximum length of the order of 3.5 m, for which there is an elongation greater than 4 mm for a temperature rise of 50 ° C.
  • the invention also relates to a tunnel caisson, intended to be integrated into the lintel of a bay of a construction and the surrounding masonry, and to house a roller shutter, and having a vault supported by two longitudinal walls whose lower edge of each is integral with a metal profile, preferably aluminum, in the form of a rail, and two shutter devices, each intended to close one respectively of the two lateral ends of said tunnel box, of cross section in form U returned, each shutter device comprising a cheek, which fits into the less partially in a lateral end of the tunnel caisson, and a heel, projecting inwardly of the tunnel caisson on the base of the inner face of the cheek and substantially perpendicular to the cheek, and which fits between the two rails when the cheek is nested in the corresponding lateral end of the tunnel box, characterized in that each of the two shutter devices is a shutter device according to the invention and as presented above.
  • the tunnel caisson 1 represented on the figure 1 consists of a molded shell made of a synthetic material, for example based on polystyrene, with a U-shaped cross-section, and having an arch 2 resting on two longitudinal walls or jambs 3 and 4, and this shell is delimited in length by two lateral ends, only one of which is visible on the figure 1 .
  • the internal recess of tunnel caisson 1 thus has the shape of a tunnel, open downwards to allow the introduction of a shutter and a drive device of the deck of the latter in the caisson-tunnel 1, and, in this example, the vault 2 is connected to each of the longitudinal walls 3 and 4 by an upper portion of the latter which is of linear thickness decreasing from the roof 2 to the lower part of the walls 3 and 4 which is vertical and of constant thickness.
  • one of the walls 3 and 4 intended to be turned towards the interior of the building, is of a thickness greater than that of the other wall 4 or 3, in order to form a thermal and acoustic insulating barrier.
  • Two reinforcing profiles or aluminum rails 6 and 7 are each fixed along the lower edge of one respectively of the walls 3 and 4, overlapping the lower edge.
  • the tunnel caisson 1 is intended to be integrated in the lintel, above the embrasure of a bay, such as a window or door, of a building, as well as in the surrounding masonry, in which it is in particular embedded by its two lateral ends such as 5 and the vault 2, and this so that the internal recess of the tunnel-box 1 opens into this embrasure or bay.
  • a bay such as a window or door
  • the surrounding masonry in which it is in particular embedded by its two lateral ends such as 5 and the vault 2, and this so that the internal recess of the tunnel-box 1 opens into this embrasure or bay.
  • each closure device 8 consists mainly of a cheek 9 and a heel 10, which are intended to be mounted laterally in the corresponding lateral end such as 5 of the tunnel caisson 1, so as to close this lateral end 5 of airtight manner coming from the internal recess of the tunnel caisson 1.
  • the cheek 9 consists of a plate 11 which, in the closed position of the lateral end 5, extends in a substantially vertical plane and perpendicular to the roof 2 and the walls 3 and 4.
  • the cheek 9 also comprises a support edge 12, which extends perpendicularly to the plate 11 along the periphery of the latter, except at its base or lower part, so that the support rim 12, thick constant in this example, consists of an arcade 13 extended by two straight segments 14.
  • the roof 2 may be semi-cylindrical, and not canted, and in this case the arch 13 has a curved shape which corresponds to that of the vault 2.
  • This support edge 12 is designed to intimately fit the internal faces of the vault 2 and the longitudinal walls 3 and 4, so as to ensure the precise positioning of the cheek 9 with respect to the lateral end such as 5, when the plate 11 is embedded at least partially in the lateral end 5 and anchored in the roof 2 by teeth 15 (three teeth 15 in this example) projecting vertically in the plane of the plate 11 on the inner edge of the arch 13 of the support rim 12, these teeth 15 coming to be embedded in the synthetic material constituting the vault 2, for example a cellular or honeycomb material or structure of honeycomb.
  • the plate 11 has, in its central part, housings 16 and 17 opening in its inner face, and provided for the support and attachment of a shutter axis and a maneuvering mechanism thereof, in particular .
  • Two duct passages 18 are also provided in the lateral parts of the plate 11, below the housings 16 and 17 and above the heel 10, which projects on the internal face of the plate 11, at the level of the base or part lower than the latter, and which extends perpendicular to the plate 11, these two sheath passages 18, each close to one of the straight segments 14 of the support edge 12, allowing the connection of an electrical sheath standard for supplying and controlling an electric motor, in the case where the drive mechanism of the roller shutter comprises such a motor.
  • the outer edge of the support edge 12 is extended, at its periphery, and in a plane parallel to that of the plate 11, by a flange 19, which therefore comprises an arcuate portion 19a and two rectilinear lateral portions 19b, of which each is in lateral projection of a straight segment 14 of the support edge 12, perpendicular to the latter.
  • This flange 19 is intended to come into contact with the facing lateral end such as 5 of the tunnel caisson 1, to act as an axial stop for the shutter device 8 when it is mounted in the closed position of this lateral end 5 of the caisson. tunnel 1.
  • the flange 19 also forms a tight barrier to the passage of air between the internal recess of the tunnel box 1 and, for example, an inner insulating lining of the wall in which the tunnel box 1 is integrated .
  • the plate 11 of the cheek 9 is fully embedded in the lateral end 5 of the tunnel box 1, after the mounting of the shutter device 8 in the closed position.
  • Each rectilinear lateral portion 19b of the collar 19 widens laterally at its lower end 19c, of shape, for example substantially trapezoidal, as shown in FIGS. Figures 1 to 3 , and a cavity 20 is formed in the inner face (turned towards the inside of the tunnel caisson 1) of this lower end 19c, so as to form a reservation capable of receiving the longitudinal end facing an aluminum rail 6 or 7, when this rail elongates by thermal expansion, because of the temperatures at which the rail 6 or 7 is carried on the facade of the building.
  • the depth of the cavity 20, in the direction of the length of the rail 6 or 7, is at least equal to X / 2 of the maximum elongation X predictable for the rail 6 or 7, taking into account maximum temperatures in frontage.
  • each cavity 20 is slightly greater than 2 mm.
  • the cavity 20 thus makes it possible to absorb the elongation of the rail 6 or 7 opposite, and therefore the displacement of the longitudinal end of the rail 6 or 7 opposite the lower end 19c considered of the collar 19 of the cheek 9 .
  • a cavity 20 is formed at each of the two lower ends such as 19c of the flange 19, the cheek 9 and therefore the device shutter 8, are reversible and can be used to close both the left-side and the right-hand end of the tunnel caisson 1.
  • this cavity 20 is formed by a localized reduction in the thickness of each lower end 19c (parallel to the longitudinal direction of the rails 6 and 7), with respect to the constant thickness of the other parts 19a and 19b of the flange 19.
  • This reduction in thickness at least 2 mm in the example above, is obtained during the molding of a single piece of the cheek 9, and preferably the shutter device 8 as a whole.
  • a shutter device 8 With a shutter device 8 according to the invention, it avoids the tensioning of the longitudinal wall 3 or 4 which is in front, during the thermal expansion of the rail 6 or 7 at its base, and simultaneously avoids the introduction of mechanical stresses in the surrounding masonry by the thermal expansion of the rail 6 or 7 considered. This avoids the formation of micro-cracks in the plaster of the facades.
