Description

The invention relates to an insulating panel and its method of manufacture.

  The subject of the invention relates in particular to sectors

  building elements and materials, in particular

  bind to form firm, pregnant, local volumes, cold rooms

  Panels commonly known as "sandwich panels" are known

  wichs "used for the realization of partitions, walls, plan-

  expensive, ceilings, and other components of a local cabin, a cold room and other insulating volumes These

  generally consist of panels or top

  and in a mold or shaper between

  injected with polyurethane foam or similar product

insulating wire.

  When it comes to forming insulating enclosures, these panels must be assembled together in a watertight manner.

  this, it is necessary to provide in the mold means and organs of posi-

  for locks, locks and other sound equipment, as well as for peripheral seals in the foam

  It is understood that this involves making a mold or conforming

  for each panel dimension This requirement requires

  A major investment in tooling and storage In addition, these complex molds must be carefully prepared

  (blocking, mounting, blocking of openings, o) for each

  ration, which presupposes a large and qualified workforce.

  Moreover, after use, it is necessary to perform a tedious net-

  toyage. The current manufacture of these panels does not offer the

  desired quality and a competitive cost price of the product obtained

  bare. In order to remedy these drawbacks and to put on the market an economical and better quality product, the panel according to the invention has been designed which is remarkable in that it consists of a plate or lower parerment and a plate

  or upper facing between which peri-

  phériques of insulating material, of sufficient structure and density to produce a rigid and dimensionally stable belt; the internal space of the insulating belt being filled by at least one plate

  made of lightweight material of low density.

  According to another characteristic applied to the realization -2 of insulating panels connected together in a sealed manner or my,

  the peripheral elements constituting the safety belt

  gide, to receive the assembly and locking members of the panels together, is fixed by gluing or otherwise, the elements thus equipped at the periphery of the lower face, it

  fills the interior space with the light material of low den-

  sity, we cover the whole with the previous siding

  affixed or otherwise prepared for attachment to the peripheral elements and the panel thus formed

a news.

  These features and many more will emerge

of the following description.

  To fix the object of the invention without however limiting it, in the accompanying drawings: FIG. 1 is a perspective view illustrating separately the elements used in the composition of an insulating panel

according to an exemplary embodiment.

  Figure 1 which has been removed the upper face.

  FIG. 3 is an enlarged sectional view taken along the line 3-3 of FIG. 2, illustrating the

panel according to Figure 1.

  FIG. 4 is a partial perspective view illustrating

  an element of angle and connection between two perpendicular panels

  res. FIGS. 5 to 10 illustrate, in perspective views, various types of panels according to the invention used for

  the construction of insulating enclosures.

  Figures 11, 12 and 13 are perspective views,

  lustrantdas pregnant formed with the panels according to the figures

to 10.

  In order to make the object of the invention more concrete, it is now described in non-limiting embodiments.

  illustrated in the figures of the drawings.

  As can be seen in particular in FIGS. 1 and 2, the panel

  according to the invention is constituted by a plate or facing

  lower (1), a plate or upper facing (2), peripheral elements (3) and at least one plate (4) adjusted in space

  internal to the peripheral elements The siding is in any case

  suitable materials such as steel, light alloys.

  In the illustrated example, applied to the production of

  insulating units to be interconnected, means (5) for assembling and locking the panels are also provided. Only two of them have been illustrated in FIG. 1 so as not to overload the drawing, it being understood that there are as many means as possible. (5) there is

  positioning lights (3a) for these means (5).

  It should be noted that the means (5) can be of any type

  and in particular, the devices that were the subject of a patent application national number 81 11455, whose applicant is also the holder In the example shown, the means (5) are locks made economically of two sheets folded

  and ribbed, between which is rotatably mounted on an

  a hook (Sa) which can be operated from outside a

  to retract the hook or place it in a position of

  locking in the means (5) complementary to another panel.

  The peripheral elements (3) intended to constitute the belt

  ture can be debited in different lengths corresponding to

  spanning the dimensions of the panels to be made.

  It is planned to realize the peripheral elements in all

  materials of good density and mechanical characteristics of

  good rigidity and good insulation.

  armed or not, wood In a particular achievement

  aimed at, the peripheral elements are economically realized at

  firing of polyurethane foam bars or material of the same type

  thousand, whose composition is studied to have a relatively high density, to satisfy the insulation requirements

and rigidity.

  The peripheral elements cut to the length then pass on a cutting tool to form the slots (3 a) for the passage of the locks (5) and the openings (3 b) for the passage of the lock operating key. orifices (3b) are made of a single element (3) with respect to the light, but it is not excluded,

  4 - as will be seen later, that the orifices open out *

on both sides.

  Of course, the step of the lights, therefore the points of ver-

  rust, is calculated based on the dimensions of the panels and the intended use. The peripheral elements (3) thus equipped with latches (5) positioned firmly in the slots by gluing or otherwise, are then attached to the periphery of the lower facing (1),

  as shown in Figure 2 For this purpose, the peripheral elements

  (3) can be assembled in a straight cut, mitered or other shape, and arranged either against walls, songs or edges of the plates, or in a blooming. Fixing can be done by all

conventional means.

  Preferably, it is applied on the inner face of the facing

(1) a suitable glue (C).

  Similarly, a layer of glue is applied to the inside face of the facing (2) and then inserted into the internal space (E) at

  peripheral elements (3), one or more plates (4) in

  light weight low density (especially polyurethane foam),

  or fill the space (E) with light materials

  In the form of particles, granules and chips it is not excluded to also provide a filling material injected into

  the space <E) Then the upper cladding (2) is glued to the 14

(3) and the plate (4).

  Sen understood, as we see in the figures of the drawings, the pa-

  (2) has orifices (2a) established at the

lower siding (1).

  As mentioned above, the passage openings of the

  key locks are provided in a single c 8 té, ie

  In other words, it is possible to pierce the orifices (3b) from one side to the other and also to pierce the lower face (1), if one wants to

  operate the locks from outside the enclosure.

  After assembly of the elements constituting the panel and passage

  panels under a press intended to ensure the solid

  In the case where one must make a sealed enclosure, it is provided that the edges of panels which leave exposed the elements (3) forming the rigid belt, a seal ( 6) type polyurethane tape, which is glued to the edges either by its adhesive side (after

  removal of a protective film), or by a glue

  In the case where the edges of the panels have one or more lights (3 a) for the passage of the lock hooks, the joints

  are cut in correspondence On the other hand, the width of the ban-

  (6) is adapted to the width of the edges of the panels, in order to

cover them perfectly.

  FIGS. 5 to 10 show different miodeles of

or auts.

  The enclosure (P) is formed of panels (P1, P2 and P4) com-

  bound together to form walls (pl, p 2, p 3, p 4), a

  floor (p 5) and a ceiling (p 6) As can be seen, the simple sign

  ple (P 1) (FIG. 5) is of the type described before, that is to say comprises

  a rigid belt (3) comple-te enclosed between two facings (1 and 2) The corner panel (P 2) (Figure 6) shows a belt r J gide (3) enclosed between a lower facing (7) squared for forr a song (7 a) and a higher facing (8) shorter on the side of said song (7 a) to reveal the belt (3) between him and

singing.

  The double-angled panel (P 4) (Figure 8) has a belt

  rigid ture (3) enclosed between a lower facing (9) squared on two c 6 tees to form two consecutive singles (9 to 9 b) and an upper facing (10) shorter along two consecutive sides

  to reveal the belt (3).

  The panels (P 3, P 5 and P 6) illustrated respectively in the

  Figures 7, 9 and 10 are used to form other types of

  For example, the enclosure illustrated in FIG. 12 is formed with panels (Pi, P 3, and P 5), while the illustrated enclosure

  Figure 13 is formed with panels (Pi, P 3 and P 6).

  The panels (P 3) are formed of a rigid belt (3) formed between a lower facing (11) square on two opposite sides to form edges (lila, 11 lb) and a top facing (12).

  shorter on two opposite sides to reveal the

  ture (3) The panels (P 5) are formed of a rigid belt (3) 6 enclosed between a lower facing (13) squared on three sides to form edges (13a, 13b, 13c) and an upper facing (14) shorter along the three sides corresponding to said edges to let appear the belt (3) The panels (P 6) are formed of a rigid belt (3) enclosed between a lower facing (15) of the type caisson for forming four songs (15 a, b, 15 c, 15 d) and a shorter upper facing (16) next

  Of course, when you have to assemble all these panels

  between them, the locking members (5) are adjusted such that

  that the face-to-face locks are complementary, that is, one has a projecting hooking means, the other

  being retracted and having a hooking part.

  The benefits are apparent from the description,

  Yet another interesting cost of the panels according to the invention is that it eliminates the molds or conformers very expensive

  and bulky, with all the operations of preparation,

  attention and cleansing that they imply, as well as by nature

  used materials that is more economical.
