Description

Heat insulated composite profile protected against fire - The invention

  relates to a heat-insulating composite profile, in particular for the production of window and door frames and the construction of facades, consisting of two metal profiles arranged at a distance from one another, which are connected to each other by at least one insulating cross-member and further, for fire protection,

  by at least one refractory anchoring element.

  The profiles thus protected mean that in case of fire

  of, the connection between the metal profiles remains

  holding and thus the danger of accident due to

who fall is avoided.

  In a composite section according to the prior art

  (substantially, according to German Patent No. 3,236,460), the

  Anchoring element is constituted by a metal plate, which the functional zone discovers, at least partially,

  formed between the metal sections of the composite profile

  site - externally to the insulating cross-member -, for

  put the introduction of seals, etc.

  The object of the invention is to construct a composite profile

  according to the prior art, so that the

  functional area remains fully maintained.

  This object is achieved, according to the invention, thanks to the fact that the metal profiles are milled in the region of the groove edges, insulating cross-member side, grooves of

  reception and the insulating cross-member, and that the element of

  the cavity housed in this milling cut in the shape of a gutter and has, at least partially, the contours of the functional area formed above the cross

insulating.

  This goal is achieved in a simple way,

  anchoring elements in the form of gutter in the milling done. According to a first embodiment of the invention, the groove edges, insulating cross-member side,

  and the ends of the insulating beam are milled

  above the upper edge of the insulating sleeper. So,

  the anchoring element then rests, in the case of

  partial contour of the functional area, flat on the bottom of the receiving grooves and on the insulating rail.

  If the functional area is to be maintained in total

  In accordance with a second embodiment of the invention, the edges of the groove, on the insulating cross-member, and the insulating cross-member are cut, and the anchoring element is given

  in section, a form with stages. Side rails can

  then rest on the bottom of the receiving grooves

  perspective, and the upper edge of the bottom of the gutter

  ends with the upper edge of the insulating sleeper.

  It is recommended to give the anchoring element the

  form of a short piece, in which case it is also

  It is possible that the part consists of an extruded profile.

  Even better stability of the link is achieved when the anchor element - seen from above - is constructed

  H-shaped or double H-shaped. In both cases, the

  Lateral flanges of the anchoring element advantageously cling behind the edges of the grooves on the insulating cross-member side. Finally, it is recommended that the element

  anchor is made leakproof compared to the metal profiles

  and the insulating sleeper.

  The invention will be described in more detail by means of

  examples of the following embodiments and the drawings

joints, on which:

  FIG. 1 is a sectional view of a composite section

  insulated, which must have an anchor

  for fire protection.

  FIG. 2a) is a sectional view of a composite profile

  insulated site in which an anchoring element is housed, and the functional zone is partially preserved,

  Figures 2b) to 2d) are top views of different

  different forms of the anchoring element,

  FIG. 3a) is a sectional view of a composite profile

  insulation site in which an anchoring element is housed, and the functional zone is integrally preserved, and Figures 3b) and 3c) are top views of

  different embodiments of the anchor element.

  The heat-insulating composite section 1 according to FIGS. 1 to 3 is, in known manner, composed of an outer metal section 2 and an inner metal section 3, which in this example are connected to each other by two insulating crosspieces 4. The metal sections 2, 3 also comprise receiving grooves 5, 6 which are delimited, on the insulating cross-member side, by groove edges 5 ', 6'. Enter

  these throat edges 5 ', 6' are formed, above the tread

  4, the so-called "functional zone", which serves in particular to receive seals and other (in Figure 1, are indicated the width B and the

height H).

  For fire protection, the metal profiles

  2, 3 are connected by metal anchoring elements

  7 (in particular screwed), which come under the

  shape of short pieces having in section the shape of a drop-

  SPECT. In general, the anchoring elements 7 are housed in

  milling of the metal sections 2, 3 and the traverse

  4. In the event of a fire, the anchoring elements 7 cause, despite the fusion or the deterioration of the insulating cross-members 4, the connection between the metal sections 2, 3

remains intact.

  In the embodiment according to Figure 2a), the

  throat edges 5 ', 6' and the ends of the iso crossbar

  4 are milled over the upper edge of the

  insulating pour 4. The anchoring element then rests flat

  on the bottom of the grooves 5, 6 and on the insulating crossbar 4.

  As the anchor element 7 in the form of a gutter rests

  on the insulating crossbar 4, it presents only partial-

  contour of the functional area (the height H 'of

  the area is smaller than the height H of the functional area

initial, H'4H).

  In the embodiment of the anchoring element 7 according to FIG. 3a), the functional zone is maintained

  as a whole. Here, the throat edges 5 ', 6' and the

  4 are milled, and the anchoring element has

  cuts a stepped form, so that the side rails

  the 8 rest on the bottom of the receiving grooves 5, 6 and that the upper edge of the gutter bottom 9 of the anchoring element 7 ends with the upper edge of the cross member

insulating 4.

  As shown in the top views of FIGS. 2b) and 3b), the anchoring elements 7 can advantageously

  to be manufactured in the form of extruded profiles.

  According to the top views of Figures 2c), 2d) and 3c), the anchoring elements 7 are constructed in the form of an H

  or double H. In the last two cases, we obtain no-

  also a good attachment of the side rails 8 behind the respective groove edges 5 'and 6'. In the form of

  embodiment according to Figures 3a) and 3c), the elements of

  7 are sealed relative to the metal profiles.
