Description

Frame in thin sheet metal, for securing an element of

  The present invention relates to a frame

  in thin sheet metal for securing a structural part-

  the translucent covering, at a distance from the ridge, an opening

  polygonal structure practiced in a roof, having an average region at least partially vertical which delimits a well of light incidence, the side facing the roof is extended by a lower region, directed towards the outside, with a view to securing with the roof, and whose side facing away from this roof is extended by another upper region, also directed towards the outside, this frame comprising, on its side facing away from the light incidence well, insulation

  thermal a6 less partially covered.

  In structures in superstructure, frames

  are structural elements necessary for the solidarisa-

  covering of openings made in roofs

  tures, whose solidarity plan must be enhanced

  above the aquifer of the cover. The ele-

  covering elements to be secured can then be in the most diverse forms, for example

  in the form of dormers or skylights, or even

  ment in the form of skylights or staggered glazing

  arranged on roofs. The cornices of lumid6-

  mes constitute a particular form of doorframes. We know doorframes made of sheet steel which consist of a base profile for securing the support structure of the glazing step and, in addition, a piece of

  angle iron and a lining sheet, door frames on which

  can be applied a thermal insulation retained,

  above roofing panels, using a metal rod-

  clamping line. So we know for example huis-

  steel series laid on concrete, including a plank

  flushed out and a crawl space used for insulation,

  these horizontal and the vertical forces being respective-

  this has repercussions on the door frame and on the roof structure.

  In these known frames, the roof covering is nailed to the plank. The upper shutter of these frames

  known is formed by an angle piece which makes sail-

  plywood, and aims to prevent penetration of water and dirt behind the roof covering. This covering (tablecloth or bitumen sheet) is brought closer to the plank by the intermediary of a corner. These known frames have the disadvantage of being relatively heavy and requiring, for

  therefore, a robust underlying structure. The concept

  tion of the thermal insulation in the form of a cavity, between the frame of the frame and the plank embedded in it

  frame, also requires a large space because of the dis-

  parallel position of the plank and the cavity: indeed, a minimum dimension of this cavity must not be exceeded negatively if one wants to achieve insulation, even

than just sufficient.

  A known arrangement, intended to receive a lantern-

  neau, is illustrated by the prospectus "Das Flutlicht von Eberspâcher" in an edition of September 1987. In this arrangement, the frame consists of a sheet of steel whose

  the upper branch is bent twice, and retains the iso-

  thermal lation in its bent part. This thermal insulation is preceded by another insulation, on which the roof covering is deposited. A "water jet", designed to prevent the ingress of moisture and grime, is

  fixed to the part of the skylight that covers the opening

  ticked in the roof. This arrangement can be used for skylights of any length, the

  widths reach up to 4 m. Nevertheless, it requires a mon.

  very complicated and factory production, which

  plics, in turn, special transportation problems

  raised by large monobloc parts. In addition, the rea-

  The illustration illustrated in this prospectus is subject to the cor-

  erosion in the solidification zone, and a fall of par-

  parts constituting thermal insulation is to be feared

during transport.

  An improvement is illustrated in the old

  Patent application P 37 19 257, not previously published.

  In this case, it is a frame intended for the solida-

  rization of a structural part covering an opening made in a roof, which preferably consists of

  polyurethane foam, possibly with a core

  gide, and is surrounded on at least three sides by a thin sheet metal frame. At its upper end, this frame has a substantially wedge-shaped appendage, acting as a "water jet", as well as metal sections which are

  embedded in the foam and can be coated with plastic

  tick for securing roof panels.

  This frame has an aesthetically pleasing shape, and

  is also very light. However, it cannot be fa-

  bricks than in the factory due to its relatively complicated form

  quée, and it requires special precautionary measures,

  during transport, to protect the water jet which is so-

  lidaire. Also in this frame, a dissociation of

  thermal insulation is to be feared during transport.

  The object of the present invention is to provide a

  frame which, thanks to a particularly pro-

  manufacturing part, can be assembled on site

  implantation without special auxiliary means; pre-

  feels great resistance to corrosion and stress

  thermal, while being of a clean realization at-

  nude-vibrations; and allows, from at least approximately identical elements, an installation according to different length / width ratios, in accordance

  with the existing opening in the roof. Con-

  according to the invention, in a frame of the coQsi- type

  this object is achieved by the fact that this frame is formed of individual elements, respectively connected to each other by means of legs which are

  formed by bending over their middle region, with faces ex-

  hopper considered, and between which an elastic trim-

  sealing tick is interposed. It then proved sufficient that the legs were shaped only on the

4 2628785

  vertical part of the middle region of the frame. The so-

  the connection of these legs can be formed by an assembly

  compressed connection. This compressed assembly represents a link

  press-button type sound, in which the incorporated gasket does not necessarily have to be present

  ter holes, but is instead embedded in the

  verture of one of the parts, by the appendix of the nodosi- type

  tee of the other party to be connected, this appendix of the

  nodosity type which may have come from stamping.

  A frame of this kind offers many advantages.

  compared to known frames. First, a

  such frames can be produced in a technical way-

  simple allowing factory prefabrication,

  that is, the individual items are factory made

  while assembly is possible, on the implant site-

  tation, without special auxiliary means. Due to the fact that these individual elements are transported to the mounting location, a layer of paint, if applicable, can also be protected by a film during transport.

  the parts to be integrated. These interventions require

  can be carried out in the factory, easily and without

2628785

  particular complexity. On the site of implantation, one proceeds to the assembly which, thanks to the joining by compression, allows a simple connection of the legs with an interlayer sealing sheet. In this way, we obtain simultaneously a frame elastic to vibrations and

  attenuating these vibrations, which vibrations can come from

  nir of the building (for example, of machines generating

  vibnrtions), or be induced from the outside, for example-

  ple by planes, which is a particular problem

  in structures built on or near aerodromes

  tee of aerodromes. Until now, in such construction projects, the known roofs were. particularly endangered by the vibrations generated. Finally, there

  The result is also a set very resistant to corrosion.

  because the individual elements can already be fitted with an appropriate anti-corrosion protection at the factory.

  As a result, and the incorporated seal provides

  re additional corrosion protection in the so-

  corner anchorages exposed to risks. Fluctuations

  temperature conditions, which can be considerable in the presence of large blankets, can also be

  controlled thanks to the incorporated sealing elements

  according to the invention. In this design from the

  note, thermal insulation can be easily installed

  place on site. This can be done

  killed as well by application (known technique), as by insertion of prefabricated blocks which can be easily

debited on site.

  Another particularly embodiment

  convenient of the invention results from the fact that a profile, available

  dried on the upper region of the thin sheet metal frame, comprises a contact branch intended for securing the structural covering part, as well as another bent branch which covers, at least in part, the thermal insulation applied to the middle region of the door frame; and the fact that a sealing strip configured in Z is interposed, flat, between the contact branch of the profile

  and the upper region of the door frame. According to a perfec-

  tction of the invention, the profile may have a jet of water formed integrally on its covering branch, at least

  in part, thermal insulation. Furthermore, he

  judicious cycling that this branch of the profile has nerves

  inwardly protruding from the thermal insulation

  than. This profile can be stored as aluminum profile

  minium extruded, and be cut to length for order

  considered. The connection with the upper region of the door

  series can be done by screwing, the seal

  configured in Z then being interposed, flat, between the profile and the upper shutter of the frame. Means can be made or brought back, on this branch

  of the profile, in order to fix or receive the covered part

  the opening made in the building. He can then

  be a reinforcing element, or also a

  including possibly the associated locking and opening mechanism. In addition, the profile has

  function of] styling the insulation in whole or in part-

  thermal tion in place, and therefore protect it. The

  ribs protruding inwards, in the thermal insulation

  help to retain this thermal insulation, which can be particularly important when it is

  fear that the insulating material will settle as a result of the occur-

  rence of vibrations. This is why the ribs can

  certainly protrude far into the insulating material, e.g.

  full to half the thickness. The water jet formed integrally then forms, in a known manner, a protection preventing the penetration of moisture or dust between the thermal insulation and the roofing panel to be

  put in place. Therefore, in accordance with a perfection-

  ment of the invention, the branch of the profile is made in

  view of the fixing of a panel-in its region located above

  below the water jet. In this case, according to another embodiment of the invention, the branch of the profile can

  present holes for fixing a clamp ring

  age, with interposition of a roofing panel. In principle,

  the roof panel is raised up to the sub-region

  adjacent to the water jet, so that moisture cannot penetrate. The fixing of this panel can, in a known manner, be ensured by gluing, but also by means of a clamping rod which is placed on said panel, then screwed with the profile. It is also possible to produce the roofing panel, in its upper region, so as to be able to form a joining of the strip type with hook-and-loop fastening system. Naturally, in the

  scope of the invention, it is also possible to extend

  manage this branch of the profile, located outside,

  denies obtaining full coverage of thermal insulation; in this embodiment, a wing is

  judiciously formed in one piece at the lower end

  higher, so that the roof panel can be engaged between this wing and the wing of the frame. Another advantageous embodiment of the invention results from the fact that a corner fastening piece, introduced into the upper region of the branch of the profile, against which

  it is applied internally, rests on one of the nerves

  vures of the branch directed inwards, and extends to the other branch of the profile. A groove can then be made or dug in the branch of the profile which bears against the upper region of the frame, in view

  of a permanent deposit of this piece of solidarisa-

angle.

  The invention will now be described in more detail.

  tailt by way of nonlimiting examples, with reference to the appended drawings in which: FIG. i is a section of a frame in accordance with the invention; Figure 2 is a section, seen in plan, along the line A-A of Figure 1; Figure 3 schematically shows a frame for a skylight; and Figure 4 schematically illustrates a frame

  designed for an octagonal opening in a roof

  ture. Figure 1 shows an opening 1 made in a roof 2 and to be covered, fixedly

8 2628785

  or with openness, through a provision

  non-illustrated covering sitive, for example a lantern-

  neau or a lumidome. A frame 3 is placed on the roof

  ture 2, to which it is rigidly connected, and delimits a well 4 of light incidence above the opening 1. This frame 3 comprises an upper region 3a directed outwards; an average region 3b, 3b 'including an area

  partial 3b extends vertically, that is to say cylindrical

  only in the direction of rotation of the longitudinal axis of the

  well 4 of light incidence, and extends, in the example

  ple of realization, by a partial frustoconical region 3b '; as well as a lower region 3c also directed outwards, that is to say away from the well 4. On the side facing away from this well 4, the frame 3 is provided

  of a thermal insulation material, for example a foam

  se of polyurethane provided with a film or a laminated lining. The placing of this material 5 can take place by brushing or by projection, doorframes then being placed one on top of the other in a sufficient number,

  until the desired material thickness is reached

  you. However, said material can also be used under

  the shape of plates cut accordingly and be, if ne-

  secondary, connected to the frame 3. In the thin sheet frame described hitherto, the region 3a can be used to receive a structural part not shown on which the covering element, covering the opening of the roof, is

  installed fixed or rotating. In the embodiment example

  presented, this region 3a, however, acts as a support and fixing wing for a profile 6. This profile 6, for example made of extruded aluminum, has a contact branch 6a by which it is fixed to the region 3a of the '' frame

  3, by means of a seal 7

  Z-shaped and lying flat. In this case, the struc-

  turelle above described, intended to receive the covering element

  truly, is fashioned from one. in one piece or attached to this region 3a (said part, however, does not fall within the scope of the present invention). Another branch 6b, connecting by an elbow to the contact branch 6a, extends

9 2628785

  preferably roughly parallel to zone 3b, even

  also 3b 'of the frame 3, and can be weak-

  spaced apart from thermal insulation 5. Preferably, more

  a number of ribs 8 directed inwards, which are also arranged integrally on the branch 6b, penetrate into the thermal insulation 5. The rib 8 closest to the contact branch 6a simultaneously serves to support

  a corner fastening piece 9, '- housed in a groove

  re 10 practiced on the contact branch 6a. This piece

  9 is only necessary when the door

  serie 3 requires a stiffening of angle, as well as

  ribs 8 are only a measure of stiffening

  very wise. A "water jet" 11 is furthermore

  ge in one piece on the branch 6b of the profile 6. This water jet serves to protect a roofing panel 12, in its contact zone below said water jet 11, by preventing a

  penetration of water or dirt, and thereby preventing

  quent said panel 12 to dissociate from the frame 3,

  respectively of the section 6 forming part of the latter-

  re. In a known manner, the roofing panel 12 can be fixed to the branch 6b by gluing, or else by making

  of the upper edge in the manner of a band with a fastening system

  hook and loop. In the exemplary embodiment, the fi-

  xation is ensured by means of a clamping ring 13 which is fixed to the branch 6b by means of screws 14, and firmly clamps the panel 12. Holes 15 can be easily drilled on site. At its other end, the panel 12 rests on the roof 2, possibly on a

  another roof panel 16 already present, and it is respec-

glued or welded.

  Figure 2 illustrates, schematically, a solida-

  corner risation such as étahlie in the presence of doorframes

  3 rectangular. This figure 2 shows legs 16 'for-

  mées, by bending, on the zone 3b of the profile-6. In the example

  full realization of a rectangular frame 3, this cou-

  dage is carried out at 45, more precisely on each side of the individual elements which form the frame 3 and are designated in a simplified manner by the same references, on

2628785

  the figures, when the embodiment is identical. The pat-

  your 16 'meet in the corner area, and are re-

  linked to each other after interposition of a sealing sheet 17. The joining preferably takes place by compressed assembly. This joining can substantially be done in the manner of press studs, or else

  individual ribs, formed by two parallel notches

  leles in the surfaces of the legs, are jointly re-

  alternately pushed forward and backward. This compressed assembly is a known process for joining

surfaces.

  Figure 3 shows schematically, as

  example, a large rectangular frame. As illus-

  very, we use in this case individual elements 3,

  3 ', 3 "which differ only in the angular position

re legs 16 '.

  Figure 4 shows, schematically, a frame for an octagonal well 4 of light incidence. This frame consists of eight identical 3 '' individual elements. All these individual elements can be quickly prepared for mounting, from a material kept in reserve at the workshop, by a corresponding adjustment 'of the legs 16'. The actual assembly is possible with conventional means in the construction field, without

particular complexity.

  It goes without saying that many modifications can

  can be brought to the door frame described and represented,

  without departing from the scope of the invention.
