Definitions

  • the present invention relates to a smoke extraction device for a curved vault.
  • Arched vaults are more and more frequently used in construction, either for their shape, for architectural purposes, or on the roofs of buildings for lighting buildings such as halls, gymnasiums, factories ...
  • This overhead lighting is generally achieved by arched polyester arches which are fixed near their ends on a base which has a frame shape surrounding the opening made in the roof of the building.
  • polyester arches are frequently made up of several identical parts fixed adjacent to the base.
  • arched arch structures such as arches having an aluminum structure and filling surfaces of acrylic glass or polycarbonate.
  • point skylights which comprise one or two opening leaves which are pivotally displaced by means of jacks.
  • opening elements in arched vaults. These opening elements are similar to a part of the roof and can pivot under the action of two jacks around an axis integral with the base to which they are fixed.
  • these opening elements should pivot at an angle of at least 140 °, which is made impossible by their weight and large surface area.
  • opening elements There are known opening elements, described in patent BE - A - 887,493, which are arranged opposite and are mounted on a tubular structure of steel or aluminum. Such a structure is relatively long and complicated to assemble and adjust on the arched arch.
  • a cross member of closed cross section is located in the middle of the opening, the opening elements coming to rest on this cross when closed.
  • the present invention aims to solve the aforementioned drawbacks and to provide a smoke extraction device for a curved vault which allows good smoke extraction and good ventilation of the building, without complicating construction and lengthening the assembly times of the curved structures and ensuring a good seal.
  • the smoke extraction device targeted by the invention is intended to equip a curved vault and comprises a support whose profile has a radius of curvature substantially equal to the radius of curvature of the curved vault, the support having two openings, and two leaves fixed to the support vis-à-vis, each leaf being adapted to close respectively an opening in a closed position, actuating means being adapted to pivotally pivot each leaf on said support symmetrically.
  • the device is characterized in that said support is made of polyester, said openings being separated by a groove forming a gutter.
  • the smoke extraction device therefore makes it possible to equip a curved vault with two leaves which can be pivoted symmetrically opposite one another and which thus serve as screens for each other, which prevents areas of turbulence is not created above the ventilation openings.
  • the ventilation, and especially the smoke extraction, are thus greatly improved.
  • the support due to its radius of curvature, is easily integrated into arched vaults, perfectly sealed.
  • the openings, surmounted by the leaves, are separated by a groove which plays the role of a gutter and in particular allows rainwater to be discharged.
  • the support being made of polyester, it can be produced by molding, in one piece, which facilitates its assembly.
  • the actuation means comprise a cylinder associated with each leaf, the rod of said cylinder being fixed to an articulation piece integral with the leaf.
  • the leaves are made of polycarbonate.
  • the smoke extraction device does not harm the lighting of the building.
  • the smoke extraction device 2 is intended to equip a curved vault 1 which allows the lighting of the building.
  • This device 2 comprises a support 4 whose profile has a radius of curvature substantially equal to the radius of curvature of the arched arch 1.
  • the support 4 has two openings 5, 6 to allow smoke extraction and ventilation of the building.
  • Two leaves 10 are fixed to the support 4 and are adapted to close the openings 5, 6 respectively in a first so-called closed position.
  • actuation means 14 are adapted to pivotally pivot each leaf on the support 4 symmetrically.
  • Each leaf 10 pivots about a pivot axis 12 parallel to the longitudinal direction of the arched arch 1.
  • each leaf 10 acts as a screen for the other leaf, which prevents air masses from accumulating above the openings 5, 6 and hindering the smoke extraction from the building.
  • Each opening 5, 6 is framed by a substantially vertical rim 7, each leaf 10 being fixed on a part of this rim 7.
  • the flanges 7 also have a curved profile parallel to the profile of the support 4.
  • the leaves 10 also have a curved shape and come to rest in the closed position on the edges 7.
  • the openings 5, 6 are separated by a groove 9, the walls 7 of which are formed by flanges 7 of each opening 5, 6 located opposite.
  • the groove 9 is parallel to the longitudinal direction of the arched arch 1.
  • This groove 9 plays a role of gutter and in particular allows rainwater to flow from the roof. The water is thus discharged through the sides of the aeration device, then through the vault 1.
  • sealing parts 18 equip the ends of the leaves 10 and guide the rainwater towards the groove 9 or towards the roof 1.
  • a cross member 8 extends in the openings 5, 6.
  • the groove 9 having a recess 20 in its walls 7 adapted to the passage of the cross member 8.
  • This cross member also has a curved shape and rests at its center in the groove 9. Des fixing means of the screw-nut type make it possible to maintain the crosspiece at the level of the groove 9 and also prevent the collapse of this groove 9.
  • This crosspiece 8 is generally made of steel.
  • the actuating means 14 are fixed on the cross-member 8, at a fixing point 15 around which they can pivot.
  • actuating means 14 comprise a jack 14 associated with each leaf 10, the rod of the jack 14 being fixed to an articulation piece 13 secured to the leaf 10.
  • This articulation piece 13 is fixed to a crosspiece 19 secured to the leaf 10 and is located near the end of the leaf 10 which is raised when the leaf 10 is opened.
  • These jacks 14 are either jacks CO2 tires which control the opening and closing of each leaf 10, or nitrogen cylinders which control the opening of the leaf, a mechanical return means making it possible to close the leaves 10.
  • the actuating means 14 are adapted to pivotly move each leaf 10 at an angle greater than 90 °.
  • the arrangement vis-à-vis the leaves allows, with an opening greater than 90 °, to have sufficient ventilation, unlike known devices with a single leaf which requires an opening at 140 °.
  • These jacks 14 are remotely controlled and can be associated with smoke or fire detectors to obtain the automatic opening of the leaves 10.
  • the entire smoke extraction device is symmetrical with respect to the longitudinal direction of the arched roof 1.
  • the smoke extraction device can be self-supporting up to 6 meters.
  • the support 4 is made of polyester and the leaves 10 are made of translucent polycarbonate, so as not to harm the lighting of the building.
  • the surface of the roof intended for lighting is not reduced by the smoke extraction devices.
  • the device of smoke extraction according to the invention is adaptable to a curved vault 1 consisting of a series of curved translucent polyester plates fixed side by side on a base 3, of the curb type.
  • the support 4 is fixed to the base by means of fixing 11 of the screw-nut type in the same way as the curved plates of the arch 1.
  • the smoke extraction device 2 is sealingly adjacent to the curved plates 32 as shown in FIG. 4.
  • the polyester arches 1 there is an overlap zone between the ventilation device 2 and the curved plates 32 in order to seal the vault.
  • the support 4 has a width parallel to the longitudinal dimension of the vault 1, between once and twice the width of a curved plate 32 in the longitudinal direction of the vault 1.
  • the length of the curved profile of the support 4 can vary from 1.5 meters to 6 meters, from centimeter to centimeter.
  • the leaves correspond substantially to an area of 2 meters by 3 meters.
  • the smoke extraction device 2 has a well defined structure at the time of its construction, which allows, during assembly, to assemble the curved plates 32 and the smoke extraction device 2 in a reproducible manner, without leaks or of operation due to mounting.
  • Arched vaults 1 typically have a radius of curvature between 3 and 3.3 meters.
  • the supports 4 are manufactured with a transverse profile whose radius of curvature is substantially equal to 3.15 m. This allows taking into account the elasticity of the polyester support, to adapt the supports 4 to all the vaults whose radius of curvature varies between 3 and 3.3 meters.
  • the support is preferably made by molding and is in one piece.
  • the smoke extraction device 2 according to the invention can also be adapted to a curved vault la made of aluminum.
  • the vaults 1a of this type have an aluminum structure 30 and filling panels 31 between the aluminum uprights. These filling panels 31 are made of polycarbonate or acrylic glass.
  • the support 4 is slightly modified on its transverse sides in order to present a surface which can be fixed in the aluminum uprights in the same way as the filling panels.
  • the leaves may have a flat surface, the edges 7 of the support 4 then having curved edges adjacent to the support 4 and straight edges on which the leaves 10.
  • the single cross-member can also be replaced by two cross-members which are fixed in a fixing piece housed in the groove 9.
  • the smoke extraction device can be adapted to any type of vault, whatever their radius of curvature.
