Abstract

The bar is basically rectangular in cross-section with top and bottom edges (7, 8) which act as supporting surfaces for at least one panel, eg. a pane of glass (3, 4), and two sides (5, 6) with lengthwise grooves (16-19) designed to remove water. The distance from the bottom of the grooves to the adjacent thrust surface on one side of the bar is greater than the corresponding distance on the other, giving an asymmetry about a lengthwise plane parallel to the two supporting surfaces and a symmetry about a plane perpendicular to those surfaces. Each of the supporting surfaces is divided into two sections by a central lengthwise channel (9, 10) which is able to receive and cooperate with the panel fixings (11-13). The bar can be made from metal tubing subjected to folding and plastic deformation, or from two folded strips joined together by welding.

Description

1 PROFILE CARRIER HAVING HIGH THERMAL RESISTANCE AND

ARRANGEMENT FOR EXAMPLE VERRIERE

COMPRISING SUCH A PROFILE.

  The present invention relates to a carrier section with high thermal resistance, and to an arrangement for example a canopy, comprising one or more of

these profiles.

  Various prior art arrangements have been described in the prior art, in particular using metal profiles such as crossbeams or risers. In the field of building and architecture, such bearing profiles are often used to form a frame, itself mounted on a support structure, for example concrete beams of a building. By making this frame one or more panels, especially

  glazed, we obtain an internal or external wall of the building.

  Although the following description is made with reference to a canopy, the scope of

  the invention must not be limited to this example, and instead extends to any arrangement in which one or more panels, glazed or opaque, insulation,

  mixed, etc., are made integral with one or more profiles according to the invention.

  For the type of arrangement mentioned above, it is common to use at least one carrier metal profile and of the type comprising at least one direct or indirect bearing surface for one or more panels such as panes. This profile has at least one longitudinal drainage recess and / or fastening means

  anchoring said panel to the arrangement.

  Commonly, such profiles are made from a flat or metal cut, and for example steel, performing a series of plastic deformations in a longitudinal direction of the profile. It is thus possible to obtain two longitudinal support songs extending in a first plane parallel to the longitudinal direction, and separated by a central recess, extending perpendicular to the

  foreground between the two supporting songs.

  Such profiles have, under normal conditions of use, good mechanical characteristics. In addition, their cost price and / or cost of implementation

  work is in general quite competitive.

  -2 - 1 However, the metal bearing profiles have the major drawback of losing their rigidity when a given threshold of ambient temperature is exceeded. In fact, the arrangements made from such profiles, are sometimes dangerous, since they can no longer perform their support function when said temperature is exceeded. In such a case, it is not uncommon to observe a collapse or collapse of the arrangement and / or panels that support it. This increases the risks during a fire close to an arrangement such as a canopy, which can

  collapse if the ambient temperature becomes too high.

  Also, the present invention aims to propose a technique that overcomes

  others, the disadvantages mentioned above, and this simple and economical way.

  For this purpose, one of the objects of the invention is a carrier metal section and of the type comprising at least one direct or indirect bearing surface for one or more panels such as panes, as well as at least one longitudinal recess of drainage and / or securing means for anchoring said panel to the profile, characterized in that it comprises two substantially identical concave elements and arranged in a different orientation of approximately 180 relative to each other and following the longitudinal direction of the profile, and in that each element has formations parallel to said direction, of which at least two constitute

  Means for interlocking with and / or positioning relative to the other element.

  Advantageously, each element has substantially the shape of a "U" in cross section, and two nested elements have a symmetry with respect to an axis

longitudinal length of the profile.

  According to a preferred embodiment, the profile defines an envelope or formwork at

  less partial thus delimiting a longitudinal cavity.

  According to another particularity of the invention, each aforementioned element is constituted by a metal piece such as sheet, plate or cutting of special steel, stainless or the like, on which the longitudinal formations are formed by deformation or

tubular and / or roller forming.

  Preferably, each element is provided with one or more lateral skirts capable of cooperating with a substantially parallel flank of the other element, and in particular with

  allow their mutual fixation by a continuous weld or the like.

  In this case in particular, the lateral skirt of each element may be arranged to allow expansion and / or adjustment of the relative position of the elements,

  less in a direction parallel to the side of the other element.

  Similarly, at least one aforementioned plastic formation of each element may be provided to allow further expansion of the latter, at least according to a

  direction perpendicular to the longitudinal direction of the profile.

  Each element has, according to a preferred example of practice of the invention, a section perpendicular to said longitudinal direction, in the form of a mortise tenon, and defines a central cylindrical groove and two lateral drainage gutters, each of these goutiers being separated from the central groove by a bearing surface, while a skirt and a lateral flank respectively extend into

  protruding from a rim, perpendicular to said surfaces.

  It is then possible that the aforementioned recess and / or the cavity of the profile, are at least partially filled with an inert material such as plaster or the like, and / or that one or more of the external surfaces of said profile are at least partially partially coated with a layer of cellulosic-based material, for example wood, the aforementioned layer of cellulosic material and / or the inert material having preferably undergone flame retardant treatment, such as absorption of inert salts by heating in an autoclave . Another object of the invention is an arrangement such as a canopy or the like, with a frame mounted on a support structure and one or more panels, for example glazed integral with said frame, characterized in that the frame comprises at least one

  profile as explained above.

  But other features and advantages of the invention will emerge more clearly from the

  detailed description of an embodiment, given solely by way of example,

  which follows and refers to the attached drawings, in which: -4 -: 1. Figure 1 is a partial sectional view of an arrangement of profiles according to the invention; Figure 2 is a schematic cross-sectional view of a profile according to the invention; Figure 3 is a partial perspective view of an arrangement similar to that of Figure 1; and Fig. 4 is a cross-sectional view of another embodiment

profile.

  In a support structure such as for example the concrete frame of a building, it is planned to make a wall, by mounting a carrier arrangement

  which are secured to one or more panels, for example glazed.

  Frequently, the arrangement is a frame or the like.

  Conventionally, such a frame comprises or consists of profiles cut and assembled so as to marry and / or adapt to the support structure. In the figures, reference numeral 1 designates generally

profiles of this type.

  In the figures, the longitudinal direction of one of the profiles 1 is perpendicular to the plane defined by X and Y axes of a coordinate system of orthogonal axes X, Y and Z (Z

  defining the longitudinal direction of this section 1). To simplify the description, we

  considers that the X axis is horizontal, while the Y and Z axes define a plane

  2 5 vertical. But, it goes without saying that the XYZ mark may have any orientation.

  Following the example of Figure 1, two panels 40 are mounted on the sections 1 and 1 ', and therefore on the arrangement of which they are part. This

  arrangement is a canopy to withstand fire and / or high temperatures.

  Within this arrangement, the profile 1 has the function of being not only carrying, but also resistant to high temperatures, that is to say higher than that which are normally conceivable with the base material which constitutes it. In the present example, this material is a steel, such as stainless or "special". The profile 1 is -5- 1 made from a steel plate, deformed along its longitudinal direction, by

  example using roller bends or tubular forming.

  From a structural point of view, the profile 1 is of the type forming a metal beam, with at least one longitudinal surface or edge 14 defining a direct or indirect support plane for one or more panels 40. For each of these profiles, two pairs

  edges 14 extend respectively along a longitudinal plane, parallel to XZ.

  Note that in Figures 1 and 3, there is shown a second section 1 'similar to 1, but whose longitudinal direction is substantially parallel to X. The panels 40 are panes, a thickness of about 5 mm . Each panel 40 may comprise a multilayer structure, such as double glazing. The panels 40 may be or comprise a transparent material or not, itself

  with high thermal resistance, such as "Pyrex" glass or the like.

  Although one or other of the panels may be in direct contact with a song 14, the illustrated arrangement relates to a canopy o, for reasons of limitation of the caloric conduction, a space is provided between the songs of support 14 and the panels 40. In other words, the panels are here indirectly in abutment against the profile. Furthermore, the profile 1 has at least one longitudinal recess 2. Note that the two edges 14 are here separated by the recess 2. A function of the recess 2, either cumulative with drainage or alternative, is to cooperate with and to allow the securing of anchoring means 3. More precisely, these

  means participate in the anchoring of the panels 40 on the section 1.

  These means 3 constituted by a bolt 31 whose shell is secured to the cavity of the profile, are conventional and do not deserve to be described further. Note however that a screw 34 of the bolt 31 can cross parallel to Y a calibration

firewall, not shown.

  In Figure 1, we see that the upper end of the screw 34, that is to say its

  end opposite the nut 31, cooperates with a blocking member of the panels 40.

  This member is a steel plate 44. For example, this plate 44 has a thickness -6 - 1 along Y of 3 to 8 mm, as well as holes for passing screws 34 (06), distant

  along the longitudinal direction Z, of approximately 300 mm.

  Hatches 401, which may be arranged between a lower or upper face of a panel 40, and a corresponding surface of either a section 1 or 1 ', or a flat 44 are shown in hatched form. function the particular insulation

  thermal arrangement, and the protection of the profiles.

  These seals are intended to form between the arrangement and its environment, a

  continuous barrier according to Z. The seals 401 consist of silicone fibers

  aluminous, or any other material with high thermal resistance. An example of their composition in% per unit mass is: A1203 = 47%; SiO2 = 52.8%; Fe203 =

  0.1%; Na = 0.2% c. Such joints withstand temperatures of the order of 1790 C.

  A pure aluminum sheet and annealed can make use of support for such a joint.

  Furthermore, the solidification of this seal and the elements or members thereof can advantageously be effected by gluing, using a rubber-based adhesive

high temperature synthetic.

  A second barrier, preferably arranged outside the seals 401, has the purpose, among other things, of obtaining a seal between the zones in communication with the internal recess 2 and the outside of the arrangement. For example, a monocomponent silicone sealant 46 with rapid polymerization of a solvent such as acetate or

  Alkoxy, is perfectly appropriate here.

  One of the main features of the invention lies in the fact that the carrier metal section 1 comprises two substantially identical concave elements A and arranged in a different orientation of approximately 180 relative to each other and in the direction Longitudinal Z of the profile 1. In other words, the profile 1 comprises two hollow elements A, arranged head to tail (and / or) with their concavities

  facing one with respect to the other.

  The assembly of two elements A defines an envelope or formwork at least partially

  the profile 1 and thus delimits a longitudinal cavity 13.

  According to the illustrated example, each element A is substantially "U" shaped, and two nested elements A have a symmetry with respect to a longitudinal axis -7 - 1 median Z '. For the profile 1 for example, this axis Z 'is parallel to Z. This is clear from FIG. 2, where each element A has on the one hand - that is to say at the level of one of its ends along Y- a section in the plane XY, in the form of tenon mortise. In addition, said end section defines a central cylindrical groove which constitutes the recess 2 explained above. It is extremely interesting to provide that the profiles 1 or 1 'exert a function drainage of condensation water in particular. They act as collectors. Thus, mainly under the effect of gravity (when the longitudinal direction forms a chosen angle relative to the horizontal), rainwater, condensation, etc., can be removed from the arrangement in which the profile 1 is integrated. For this purpose, two lateral drainage channels 51 and 52 are each arranged so that the central groove is separated by a bearing surface 14. Thus, on the

  Figure 3, the Y axis has an inclination or slope of a few degrees.

  In addition, each element A has formations parallel to said direction, of which at least two define interlocking means with and / or positioning

  relative to the other element. These trainings are described below.

  On the other hand, each element A is laterally provided with a skirt and a flank. A side skirt 71 comprises a wall substantially parallel to the plane YZ, which extends from the gutter 51. At the end of this wall, and therefore opposite the gutter 51, the skirt 71 defines two bends at right angles . The first of these elbows defines a plane 715 which extends inwardly of the cavity 13. The second elbow orients the skirt

71 again parallel to XY.

  The blank 72 of the same element A forms a wall generally parallel to 71, but

  extending from the other goutière 52.

  Generally speaking, a skirt and a lateral flank respectively extend into

  protruding from a rim, perpendicular to said surfaces.

  In view of Figure 1, it is understood that the skirt 71 can cooperate with the blank 72 and with the convex face - and thus inner- of the gutter 52 of the other element A. Plus -8 - 1 precisely, the plane 715 comes to rest against the formation that constitutes the back of

the mouth 52.

  Thanks to these formations of positioning and immobilization of the profile 1, internal projections (51, 52) are therefore able to form stops for the base of the metal profile, in order to locate it along Y. Similarly, the skirts and blanks 71 , 72 are able to immobilize or position the metal profile 1 according to X. However, the lateral skirt 71 of each element A is arranged to allow adjustment and / or expansion of the relative position of the assembled elements, at least in a direction parallel to the flank 72 of the other element A, that is to say along Y. The skirt 71 is also adapted to cooperate with the flank 72 of the other element, in particular to allow their attachment, when a relative position of the two elements A is obtained. An effective way to mutually fasten two elements A to form a profile 1, is to achieve a continuous weld such as those designated 9 in the figures. Note that for this purpose, an inward clearance of the profile is provided on the skirts 71 of the elements A. The thickness of this clearance along X substantially corresponds to that of the blank 72 of the other element, so that last and the skirt 71 are flush. The weld 9 is preferably

  performed at this clearance.

  Since the two elements constituting a profile I are only fixed to each other by the welds 9, an expansion of the profile, at least in a direction perpendicular to the longitudinal direction Z is possible. In other words, the positioning formations 71, 72, 51, 52 provide sufficient clearance within the profile so that, in case of thermal variation, the material of the elements A can expand freely. This limits the appearance of internal stresses and improves the holding

of the profile.

  In order to further increase this strength, one or more of the outer surfaces of said section 1 may be at least partially coated with a layer 5 of base material.

  cellulosic, and for example of wood.

  It will be noted that the interior of the profile 1 which defines the cavity 13 is filled with an inert material 6, such as plaster or the like. This filling 6 can either be obtained by placing in the cavity 13 of a pre-formed part, or as here by casting a fluid material and solidifying. It is then easy to completely drown or at least partially fill the inside of the profile. The above-mentioned layer 5 of cellulosic material, and / or the filling 6 have been flame-retarded, such as absorption of the inert salts by heating in an autoclave. Flame retardant treatment techniques are varied and known to those skilled in the art. Also, depending on the chosen subjects, appropriate treatments may be

  easily be determined by a person skilled in the art. Their complete description is

so superfluous here.

  Any arrangement such as a canopy or the like, with a support structure or support, a frame mounted on this structure and one or more panels 40, for example glazed integral with said frame, is also in the field of the present

  invention, if it comprises at least one profile 1 as described and illustrated here.

  FIG. 1 shows assembling systems 100, which make it possible to join two or more profiled beams 1, 1 ', etc. Each system 100 comprises a finger 150 mounted on a profile 1 'and intended to be housed in a corresponding orifice formed in a wall of another profile 1. More precisely, the system 100 has a support sleeve of the finger 115, adapted to be housed in the cavity 13 of the profile 1 '. This sleeve which is disposed near the interior of the groove 2 and the surface 14, is fixed by a screw 114, on the profile which supports it, and in the longitudinal direction of the latter. It is therefore possible to mount four systems

  link 100 at each longitudinal end of a profile.

  Note that the end of the beam is cut in a shape generally corresponding to that of the side edge of the beam 1, in the XY plane. This cutout therefore comprises a plane face facing the skirt and blank (71, 72) of the profile 1, and a bevel protruding near the panel 40. The lower face of this bevel rests on an edge of the profile 1, defined 51. In addition, a next game X is

  formed between the profiles 1 and 1 ', to allow their expansion.

  Secret attempts have been made with an arrangement such as that which has just been described. The results are excellent, since after more than 2 hours of maintenance at a temperature such that the windows 40 are heated to red, the canopy has suffered no subsidence. The invention is therefore particularly effective, and also a simplicity and a cost, both for the manufacture of profiles and for their implementation.

in place, very interesting.

  Figure 4 illustrates another embodiment of the profile according to the invention, and for which the numerical references used above are repeated. The main difference between this profile and those of FIGS. 1 to 3 resides in the parallel assembling formations of the concave elements A. In fact, the two elements mutually position themselves with median edges parallel to the XY plane. and formed in pairs facing each other, at the bottom of each

recess 2.

  In other words, each element A comprises two aretes (replacing the skirts and sidewalls 71, 72) arranged in the same plane -the middle plane or plane plane of the profile 1. The two elements are for example assembled by a pair of continuous welds 9, perpendicular in the XY plane and extending to the bottom of

recesses 2.

  The invention is not limited to the embodiment that has just been described, but includes all the equivalents and combinations of the illustrated technical means. Thus, the invention can be applied to any other metal profile. Profiles such as IPN, for example extruded aluminum, or beams of high temperature sensitive material, can replace the profile mentioned here, in the

framework of the invention.

  Note that depending on the case, the formations, welds or joints 401, 46 are continuous or discontinuous in the logitudinal direction of the profile. This remark

  also applies to the filling 6 described later.
