Definitions

  • the present invention relates to a profile and its use to produce a sandwich panel system for building facades, with collaborating walls, provided with a self-supporting pultruded frame comprising such a profile.
  • facade panels means that a panel consists of different layers attached to each other. Indeed, the facade panels are generally formed (from the inside to the outside of the building) of an inner lining, a sheet, at least one layer of insulation, and an outer coating.
  • collaboration means that the various elements of the panel contribute to the mechanical strength of the structure, in particular the wind resistance. This resistance is reflected, inter alia, by the fact that the thermal expansion of the material constituting the outer coating is close to the thermal expansion of the Pultruded structure and / or the metal sheet, which makes it possible to limit the so-called “double” effects. "blade”, separation between the outer coating and the Pultruded structure responsible for warping the walls, without the need for additional reinforcements.
  • Pultruded a profile obtained by a pultrusion process. Pultrusion consists in continuously making profiles, usually rectilinear, with constant section. For this, the materials used are generally polymer matrix composites reinforced with fibers (glass, or carbon in the most common cases). The profile thus obtained has the advantage of having, beyond its good mechanical properties, a fire resistance, as well as good electrical and thermal insulation. It is also very resistant to bad weather and chemical agents for the durability of the structure. These features make the use of such a profile particularly suitable for producing frames for making sandwich panels for facades.
  • the currently used panels generally have a large footprint to meet the standards in force (especially that concerning thermal insulation). This size has a direct impact on the marketable surface of the building.
  • the objective is to meet the criteria defined in the new standards, especially from a thermal point of view, while reducing the size of the structure.
  • Cementitious matrix materials such as glass-cement composites (CCV) or high-performance fiber-reinforced concretes (UHPCs), are commonly used to make exterior cladding of facade panels. These materials provide the advantage of having good durability, withstanding shocks, being waterproof and having good structural capacity (stiffener).
  • the invention has many advantages.
  • the stiffness and the comparable coefficients of thermal expansion of the CCV and the steel make it possible to arrange the inertia of the panel around the frame made according to a pultruded profile.
  • the use of cementitious matrix material also makes it possible to make the wall collaborating and to remedy the above disadvantages.
  • the invention aims to remedy these drawbacks by proposing a panel provided with a pultruded frame capable of being suspended from the structure of a building, frame at the bottom of which can be fixed the wall CCV (or any other material whose characteristics make the wall collaborative). Thus, it is possible to adjust the position of the panel from above, which facilitates installation.
  • the mounting system is similar to the manicured facades (possibility of connection, connection and integration to a global carpentry project).
  • tubular means that the profile, regardless of the shape of its section, is hollow. Thus, when using the profile, it allows to pass, for example, insulation or metal fasteners.
  • wall means each of the solid parts, whatever their shape, which together form the profile.
  • Inner means the wall in contact with the panel to which the frame is attached.
  • outside is meant the wall to which another frame will be fixed.
  • front and “dorsal” the walls of the profile located respectively inward and outward of the building when the facade panel is set up.
  • the outer face of at least one of said front and rear walls of said profile is provided with a longitudinal groove.
  • Said groove can receive a flexible seal, and can also be used to form a cutting edge of the profile.
  • the groove any groove profile dug in the wall.
  • the groove is of smaller dimensions, so that it is not confused with the empty spaces (also called “grooves") of the crenellations.
  • its dimensions are such that when it receives a flexible seal for example, the seal fills the entire section of the groove so as to limit infiltration, for example water.
  • the inner face of at least one of said front and rear walls of said profile is provided with a longitudinal rib.
  • rib any material element in relief on the surface of a wall.
  • a rib preferably forms an extra thickness of material.
  • the rib is adapted to serve as a necking of a joinery element in the case where the profile is cut in half so that each half-profile comprises a half-rib.
  • the rib must therefore have dimensions such that it can retain an element when it serves as a constriction. These dimensions are then dimensioned by the engineer of the office of study according to the material of the profile and the structure of the element to be retained.
  • front and back walls do not include slots on their outer face and thus serves as a key during use of the profile, especially in the case where the profile would have a square section.
  • said groove and said rib have a single plane of symmetry.
  • each half-section identically comprises a half-groove and a half-rib.
  • the groove then preferably being the only element in relief of the external face of the frontal or dorsal wall on which it is located, thus marks a mark during the cutting of the profile, ensuring that the half-profile then comprises a half-groove to serve as a shrink.
  • the inner and outer walls are identical, and the front and rear walls are identical.
  • identical means that the walls have a chirality or a symmetry between them.
  • said slots have a dovetail section.
  • said slots are formed in the thickness of said outer and inner walls so that solid portions are located on the lateral edges of said walls. This again makes it possible to ensure that the external faces of the front and back walls are the most regular, even planar, possible to ensure a better seal when internal and / or external coatings are applied to the profile when it serves the realization of a frame for the manufacture of a panel for example.
  • Such a profile then has the advantage of being able to be cut and adjusted on demand to make a façade panel frame regardless of its dimensions.
  • a frame according to the present invention provides the advantage of being an excellent thermal breaker.
  • the lining comprises a front face and a back face which are respectively flush with the outer face of said front wall and the outer face of said back wall of said profile.
  • the external faces of the frame and the lining can thus be covered with the inner and outer coatings without presenting irregularities on the surface.
  • the external finishing element is a collaborating wall made of a cementitious matrix material, preferably a glass cement composite (CCV).
  • CCV glass cement composite
  • the frame is shaped to receive a central core.
  • the central core strengthens the structure's safety against fire, particularly fighting against the chimney effect.
  • the present invention also comprises a method of manufacturing a tubular section as described above.
  • the profile is pultruded.
  • a profile is cut along the groove to form two half-profiles each comprising a half-rib delimiting a necking. Said restrreint then makes it possible to ensure the fixing of carpentry elements.
  • the present invention comprises a use of a sandwich structure facade panel as described above.
  • the panels are suspended from the front by the frame and the position of said panel is adjusted from above.
  • the connection between the panel and the frame allows differential expansion movements between the outer facing and the frame.
  • the frames are provided at any height, an arm with a hook shape for hanging the panel to the building structure.
  • the slots (N11, N12) have a dovetail section, whatever the shape of the dovetails. Indeed, the slots (N11, N12) may have round or more pointed shapes but still retain their character dovetail. These slots (N11, N12) consist of grooves (N11) and heads (N12) of complementary shapes. The profile and the geometry of the slots (N11, N12) can be identical or variable along the same wall.
  • the dovetail shape of the slots (N11, N12) has many advantages. Indeed, the grooves (N11) said slots thus form hanging systems where the connectors (52, 53, 57, 58) can be fixed.
  • the connectors (52, 53, 57, 58) have a certain flexibility in order to be able to slide, in a guided manner, into the grooves of the crenellations (N11) in order to make up for the differences in thermal expansion of the various elements without generating any stresses at within the structure.
  • These connectors (52, 53, 57, 58) may, for example, be staples, consisting of elastically deformable blades.
  • the layers of insulating material may, for example, be mineral wool or vacuum insulator.
  • the outer finishing element N4 is a composite glass-fiber composite (CCV) panel.
  • the panel M is identical to the panel N, but variations are possible.
  • the number, the thickness or the type of insulation layers (M21, M22) may differ.
  • Type N1 frames (respectively M1) are able to receive inner cores of type 1 or type 2 cores.
  • Type 1 cores are solid elements, whereas type 2 cores are hollow elements. These cores 1 allow in particular to fight against "chimney effects".
  • the inside of the profile can also be left empty.
  • the space for receiving a central core can also be delimited so as to form voids 7 (cf. figure 7 ) isolating the rib N13 (or M13) which can serve as shrinkage.
  • voids 7 cf. figure 7
  • M13 rib N13
  • the embodiment of the figure 7 increases the size of the thermal and acoustic switches (element 32) and thus greatly increases the insulating properties of the panel.
  • the frames on either side of a panel N may be identical or different. That is to say, a panel N (respectively M) can be provided on either side by two frames of type N1 (respectively M1), or two frames of type N6 (respectively M6), or a N1 type frame (respectively M1) on one side and a N6 type frame (respectively M6) on the other.
  • a panel N with a frame N1 may, according to another embodiment, be linked to an N6-type frame serving as an intermediate for holding a joinery element 4.
  • a N6-type frame is attached to N-type frame with joining elements 3.
  • An N-panel can also be directly fitted with an N6-type frame used to hold a joinery element 4.
  • a N6-type frame could also be placed in a panel to allow, for example, to fix a frame that would constitute a window.
  • the N63 half-ribs located on the N6d and N6f front walls of a N6 frame serve to shrink to maintain a carpentry element 4 by an end 41 of adequate shape.
  • a panel N can be joined to a panel M by means of connecting elements 3 fixed to the frame N1 of the panel N and to the frame M1 of the panel M.
  • the fire / mechanical connection elements 33 and 34 may be fixed to one another by fastening elements 51, for example by a nail.
  • the fastening elements (51, 54, 55) may, in some cases, be identical. These elements (51, 54, 55) can equally well be nails, screws, or others.
  • figure 6 schematically represents a portion of the frame N1, intended to be arranged vertically on one side of a panel N.
  • the frame N1 then comprises an arm 6 for hanging an N panel in front of a building.
  • the suspension of the panel N can be done via the end 61 of the hook-shaped arm 6, said hook coming, for example, to rest on a rail previously fixed to the structure of the building, or at the edge of a landing, or still on any complementary shape provided for this purpose present in the structure of the building.
  • the position of said panel N can be adjusted horizontally (for example by sliding on the rail) and vertically through the adjustment element 62, which can be a screw.
