Definitions

  • the invention relates to a long and very long-lasting fire-resistant chassis for the protection of premises at risk as described in DE-A-37 15 055 and forming the preamble of claim 1.
  • a glass panel, 50mm thick, is held laterally by two clipped glazing beads. Experience has shown that this type of attachment is insufficient. No casing covering is planned. In the event of a fire, the glass panel deforms in protrusion towards the fire, emerges from the glazing beads which it deforms and falls, ceasing to fulfill its firebreak function. This phenomenon is accentuated by the type of fixation of the framework on the masonry bay.
  • the object of the fire-rated frame according to the invention is to overcome these drawbacks and to increase the fire resistance to more than two hours.
  • the fire-resistant frame according to the invention is described in claim 1, characterizing part.
  • the three transparent multilayer glass groups ensuring the fire break function and constituting the glass volume are each composed of at least five panes with very high fire resistance joined peripherally at the mirror shop with a rigid interlayer between each pan and an air space more important between each multilayer group, defined by spacers.
  • These three multilayer groups are rigidly held between tubular glazing bead profiles after interposition of strips of very compact ceramic fibers or the like cooperating with a silicone seal; the end of the three glass groups is supported on a first strip of thermally deformable insulating material, of the order of 3mm thick, acting as compensation for dimensional deviations, itself supported on a distribution plate in rigid thermal insulating material of the order of 5mm thick.
  • the peripheral structure and the means internal to said chassis consist of at least four metallic tubular profiles of closed rectangular section, protected against corrosion, the long side of which is arranged vertically. Between these sections, intermediate bars of rigid material with a high coefficient of thermal insulation have been placed. These profiles and bars are rigidly assembled together by welded or screwed means.
  • the means ensuring a rigid holding function of the transparent multi-layer glass groups comprise identical glazing profiles of square or rectangular cross section; they are made integral with the external profile of the peripheral structure of the chassis.
  • the fixing of the glazing bead profiles is stiffened by means of bars, in flat steel welded to the glazing bead profile and to the corresponding external profile of the structure; on the side not exposed to fire, the bar is welded only on the glazing bead profile and screwed onto the exterior profile; for the internal structural elements, the large bars are joined by welding to the two glazing beads, either by screw, or by welding to the external structural profile depending on whether they are removable or not.
  • the means, providing an aesthetic cover function for the external parts of the chassis is constituted by a first section of sheet steel folded substantially in the shape of an L, its small wing comprises a support ply on the corresponding glazing strip profile. A second cover profile is used for the internal parts of the chassis structure.
  • the means, ensuring the functions: of immobilizing the chassis in the bay, of top and bottom lateral guidance and of free vertical and horizontal expansion of said chassis in the bay without introducing any mechanical stress on the glass volumes, are each constituted by a screw or a rod engaged in the oblong opening of a plate secured to an adjusting screw and in a yoke secured to a second screw.
  • the rod has at its lower end an anti-extraction means of said screw.
  • the means, ensuring the functions: of supporting the chassis in the lower part in the bay, of high and low lateral guidance and of free vertical and horizontal expansion of said chassis in the bay without introducing any mechanical stress on the glass volumes are each constituted by lower support stops and upper guide.
  • the lower and upper stops each consist of a metal plate secured to the wall by screws, onto which is welded a parallelepipedal support block on which is engaged a U-shaped lateral slide secured to the metal structure of the chassis.
  • the block of lower stops is supported on a counter plate on which it can slide during expansion.
  • the upper stop comprises a block that is significantly lower than the support block ensuring the function of a side slide shoe in cooperation with the corresponding slide and provides sufficient expansion space for the chassis.
  • the fire-rated frame according to the invention consists of a structure peripheral support 3 inside which structural elements 4, 5, 6, 7 cooperate to maintain five glass volumes 8, 9, 10, 11, 12 constituting the fire-resistant glazing.
  • the long side of four of them 8, 9, 10, 11 is arranged vertically.
  • the long side of the volume 12 is arranged horizontally.
  • the location of bars 13 for reinforcing glazing beads has been shown on the entire structure.
  • the length of the lower glazing 12 is of the order of 2 meters and its height of the order of 0.800 m.
  • the dimensions of the chassis shown are of the order of 3m x 3m.
  • This chassis rests in the lower part on 5 lateral guide slide stops 14 described later with reference to the drawings fig. 14, 15. It is held laterally in the upper part by five similar slide stops 15 leaving a play largely sufficient to allow the free vertical expansion of the chassis.
  • the support structure 3 is immobilized longitudinally in the slide stops 14, 15 by means of three fasteners 16 shown and described further on in FIGS. 11, 12.
  • the ends of the elements 4, 5, 6, 7 are welded to the peripheral structure and between them so as to give great rigidity to the chassis.
  • Figs. 2 and 3 show, in cross section, an example of the construction of the structure of the fire chassis. It comprises at least four metallic tubular profiles of closed rectangular section, preferably anti-corrosion protected, the long side of which is arranged vertically. Between these sections, intermediate bars 21 of rigid material with a high coefficient of thermal insulation have been placed. These profiles and bars are assembled by means of a set of spacer rods 22 staggered passing through the bars 21 and welded to the profiles. As a variant, the rods 22 are replaced by screws 23 arranged in the same way and screwed into nut-inserts 24.
  • Fig.4 shows, in cross section, a first cover profile in folded sheet metal substantially in the shape of L. It includes an angle iron 28 in folded sheet welded to the large wing 29, on the side of the small wing 30, which is provided a fold 31 resting on the corresponding glazing bead profile. This cover is used for the peripheral part of the structure.
  • Fig.5 shows a second cover profile used for the internal parts of the chassis structure. It is U-shaped, each of the short sides 32 of which is identical to the side 30 of the first profile and has a fold 31 of inward support. The folds 31 are each supported on a glazing bead profile.
  • Fig. 6 shows, in cross section, a glazing bead profile of square section. This profile is either in drawn steel or closed by welding, or in composite material with very high resistance to high temperatures.
  • Fig.7 schematically shows a horizontal cross section along A of Fig.1 of the fire-resistant chassis 3. It is embedded in the interior 1 of the open bay in the concrete wall 2.
  • the peripheral structural elements are protected by the first cover profile 39 in FIG. 4.
  • the internal structural elements 37, 38 are protected by the second cover profile 40 of FIG. 5.
  • the chassis is secured to the wall 2 by fasteners 16.
  • a filling material 41 completes the thermal insulation between the fire-resistant chassis 3 and the concrete wall 2.
  • Fig.8 schematically shows a vertical cross section along B of Fig.1. It has in the lower part the abutments 14 for supporting and lateral guidance of the horizontal element 42, of the chassis 2, and in the upper part the abutments 15 for lateral guidance of the horizontal element 43 of the chassis.
  • Fig.9 shows in cross section, the detail D of Fig.7 and 8 showing, on an enlarged scale, the assembly of the glass volume 12 on the periphery of the structure 42 of the frame 2 and the connection inside 1 of bay 2 by means of a thermally insulating filling material. It is made of fibers with very low heat transfer coefficient.
  • the glass volume 12 comprises three identical multilayer groups 50, 51, 52, each consisting of at least 5 panes 53 joined peripherally to the mirror shop, with an interlayer 54 between each pane. A larger air gap 55 separates each multilayer group. It is defined by spacers 56.
  • the three multilayer groups 50, 51, 52 are held between the glazing bead profiles 57, 58 after interposition of strips 59, 60 of very compact ceramic fibers or the like.
  • the end of the three glass groups is supported on a first strip of relatively deformable thermally insulating material 61, of the order of 3 mm thick. It is intended to make up for dimensional differences. It is supported on a distribution plate made of rigid thermal insulating material 62 of the order of 5mm thick.
  • the glazing beads profiles are made integral with the peripheral structure 42 of the chassis by screws 64 screwed into a corresponding insert 65 secured to the corresponding profile 20 of said structure 42. To avoid tilting the glazing beads profiles 57, 58, by deformation under the pressure of the glass groups deforming under the action of fire, their assembly has been stiffened by means of bars 13 in flat steel welded to the glazing bead profile 57 and to the profile 20 outside the structure.
  • the bar On the inside, the bar is welded only on the glazing bead profile; like the glazing bead profile, it is screwed onto the external profile 20 of the structure so as to allow the assembly of the glass groups.
  • the cover profile 39 of fig.4 is slid supported on the glazing bead 57 and 58 and the angle iron 28 is supported on the small outer side of the profile 20 structure.
  • a strip 67 made of extremely insulating material, is glued to the inside of the cowling and is supported on the bars 13 and on the glazing bead profile. It cooperates with a silicone seal 68 which perfects the thermal protection seal in line with the glazing bead profile.
  • the thermal seal between the end of the covers 39 and the concrete wall 1 is ensured by a silicone seal 74.
  • Fig.10 shows, in cross section, the detail C of Fig.7 and 8 of the assembly of two glass volumes, arranged on each side of an internal structural element 7 of the frame, symmetrically thereto according to a axis XX '.
  • the glass groups 50, 51, 52 are mounted identically to FIG. 9 on the element 7.
  • the glazing beads 57 and 69 have been thermally protected by means of a cover profile 40 FIG. 5, slid over these glazing beads .
  • a strip of material 67 which is very thermally insulating was bonded to the inner face of these cowlings.
  • the glazing beads 57, 69 and 58, 70 are stiffened by welded bars 71, 72. On the removable side, the glazing beads and the bars are assembled by screws on the external profile 20 of the structure 7.
  • Fig.11 and 12 show an example of means ensuring both the immobilization function of the chassis 3, in the bay, by one of its vertical uprights and the free vertical expansion of said chassis.
  • the chassis is equipped with three threaded adjusting rods 75 each screwed into an insert nut 76 and locked in position by a lock nut 77 on the chassis.
  • the rod 75 is welded to a plate 78 provided with an oblong slot 79 allowing the correction of the positioning deviations of a vertical screw 80 engaged in the slot 79 and in the corresponding hole of a yoke 81.

  • the lower stop 13 consists of a metal support plate 90, secured to the wall 2 by two screws 91.
  • a parallelepipedal block 92 is welded to this plate.
  • a lateral slide 93, sheet metal folded in the shape of a U is secured to the metal structure of the chassis 3 by means of screws 94 or welds. It is engaged on block 92 acting as a skate.
  • This block 92 is supported on a backing plate 95, disposed in the slide 93, on which it can slide during expansion.
  • the upper stop 15, fig. 15, is identical to the stop 14, but its block 96 is much lower than the block 92. It only acts as a side slide and leaves a space for expansion of the chassis.
  • FIG. 16 two frames 98, 99 have been shown schematically arranged side by side in a bay. Only the chassis 98 is secured to the concrete wall by fasteners 100. The spaces 101 and 102 between the chassis and the opening, as well as the other peripheral spaces, are filled with a mattress of fibers 41 which are very thermally insulating.
