Description

60 MINUTES WINDOW GLASS WINDOW PARTITION:

The invention relates to a chassis of the fixed type, opening or

sliding as a component of a continuous wall, thanks to its system of free expansion (not rigid), venetric firebreak or a continuous wall

horizontal firebreak or shooting varrièra firebreak, of medium or long duration, composed of one or more. chassis assembled for your protection of premises, at high risk.

There are currently 60-minute fire frames; a 21mm glass panel of medium size and maintained

laterally pat stapled glazing beads. The experience has

demonstrated the insignificance of glass volumes and the inadequacy of this type of attachment. None, casing cover is planned. In the event of a fire, the glass panel deforms into

protrusion against the fire, emerges from the glazing beads which it deforms and falls, ceasing to fulfill its function as a firebreak. This phenomenon is accentuated by the type of fixing of the frame on the masonry bay, In effect and, fixing rods

rigidly secure the frame to the masonry. As a result, no expansion is possible. The frame structure deforms laterally accentuating the possibility of disengaging the glass panel from its paracloses. In addition, the longitudinal and / or vertical extension of the partition is not possible.

The partitions are limited to your maximum height of 3 meters for a maximum length of 6 meters. Reinforced concrete posts or beams must be inserted at the ends in case of their widening in a row. This or these posts, or beams go against the aesthetic research of the architect because they limit the "transparency" of the facade. The glass volumes inside the chassis making up the bulkhead are of significantly lower dimensions.

The purpose of the fire-rated glass partition according to the invention is to overcome these drawbacks and to increase, for transparent surfaces, the resistance to fire over more than an hour, in order to benefit from a dimensional extension of the volumes. glassmakers as well as the possibility of construction of the partitions without limit in the longitudinal direction and in the vertical direction thanks to a system of pre-frame permitting a longitudinal and vertical expansion.

According to a preferred embodiment, the firewall according to the invention consists:

- a group of transparent multi-layer means resistant to tamperatures greater than 1,000 degrees, ensuring a firebreak function greater than one hour;

- insulation means ensuring a rigid holding function of the transparent multilayer means;

- Peripheral means and means internal to the chassis, ensuring a very rigid support structure function of and with the multilayer group ensuring the fire stop function;

- Means ensuring free expansion of the shooting fire wall, without being rigidly fixed to the support;

- Means ensuring the free expansion of the pre-frame allowing the free expansion of the partition, without being rigidly fixed to the support;

- means ensuring a thermal insulation function between the transparent multi-layer means and the means for holding the latter to the support structure;

- da means ensuring a thermal insulation function between the constituent elements of the support structure;

- a means ensuring functions: thermal insulation, filling of intermediate spaces, backlash of clearances between the partition and the concrete wall, between the partition and compensator for vertical and horizontal expansion of the partition.

- means ensuring watertightness with respect to water and water;

- Means ensuring an aesthetic hooding function and insulating the internal and external parts of the chassis making up said partition;

- Means ensuring a very significant reduction function da the padding of the rigid means for holding the transparent multi-layer means and its support structure;

- Means ensuring functions: immobilization of the chassis forming the partition in the masonry opening, support in the lower part, top and bottom lateral guidance and free vartical and horizontal expansion of said partition in the opening of masonry without introducing any mechanical stress on the glass volumes, during the fire.

The transparent multilayer glass group ensuring the firebreak function and constituting the glass volume, is composed of at least five panes with very high fire resistance, joined together at the mirror shop with a rigid interlayer between each pane. This multi-layer group is rigidly held between the support profile and the glazing bead after interposition of a strip of ceramic or similar fibers. very compact cooperating with a silicone seal and aesthetically finished with an elastomer seal; the end of the glass group is supported on a distribution plate made of rigid thermal insulating material. The peripheral structure and the means internal to said partition, consist of several groups of folded sheets, protected against corrosion. The interior of the profile thus formed is filled with bundles of silica and alumina wires assembled and compressed, with a high coefficient of thermal insulation. Between folded sheet sections, an intermediate spacer made of rigid material with a high thermal insulation coefficient was placed on each side in order to obtain a thermal break. These sections separated by a spacer are rigidly assembled between them by rivated or welded means to form barras, structures of the chassis constructions, cut and then welded.

These means ensuring a ligide maintenance function of the transparent multi-layer varrier groups are arranged on one side forming part of the immobila profile and on the other side of the removable paracloses made integral with the profile by means of screw buttons.

The fixing of the glazed bead profiles is stiffened by means of a cover made of folded sheet steel stapled on the profile

glazing bead.

For internal structural elements, the cover as well

secured to the two glazing beads, on the outside of the

structure, is removable.

The means, ensuring an aesthetic function of the external parts of the chassis, is constituted by this section of sheet steel folded substantially in the shape of a "U", its small aila has a support fold stapled to the corresponding glazing strip.

A second cover profile is used for the internal parts of the chassis structure. It was made of sheet steel folded in the shape of a "U", each of the small sides of which is identical to the side of the profiled pram tree and has a support ply inside, so as to form a reinforcement to be welded or riveted. to the load-bearing profile via the thermal break spacer. The supporting profile consists of a steel sheet folded substantially in the shape of a letter "omega", filled with the same felt of silica fiber and alumina with very high thermal insulation.

The two wings of the profile are welded or riveted through the thermal break on the hood and the two ends of the profile teta in the shape of an "omega" letter are fitted with screw-buttons for holding the glazing beads on the opposite side. The means ensuring a very significant reduction function in the temperature of the rigid means for maintaining transparent glass volumes, are constituted by the strip of felt with very high coefficient of thermal insulation, bonded to the internal face of the cover profiles and the thermal seal between the ends of the cowlings and the concrete wall, is ensured by a flat iron joint cover, supplemented with silicone. The means, ensuring the functions: of immobilization of the partition in the masonry opening, of top and bottom lateral guidance and of free vertical and horizontal expansion of said partition in the bay without introducing any mechanical stress on the varrirt volumes, are each consisting of a square steel tube fixed to the masonry serving as pre-frame.

The means, ensuring the functions: of support, of the chassis in the lower part in the bay, of lateral guide up and down and of free varticala and horizontal expansion of said partition in the bay without introducing any mechanical stress on the glass volumes, are each made up of the same pre-frame in tubc steel serving as a lower support and guide

superior.

The longitudinal and vaitical peripheral frame, with a steel tube, is fixed to the masonry by a means forming part of the invention and comprising oblong holes ensuring the expansion of the longitudinal frame, then removed from the

masonry by a round tube sheath of the same outside diameter as the oblong hole of the frame, and of the same inside diameter as the diameter of the bolt screwed to the steel dowel introduced into the masonry, and serving to fix the frame. In this way, the frame in case of heating, despite its insulation by loose ceramic wool, with very high insulation power, can expand in both directions.

This pre-frame carries means of connection between several partitions at the places provided for expansion between the partitions in succession one next to the other or one overhanging the other, by a rectangular tube allowing both the maintenance and this said expansion.

The advantages of the fire barrier according to the invention are as follows:

- the chassis of which it was composed provide the firebreak function for more than one step;

- it allows to have a glass volume inside chassis, longitudinal at least twice as long as has been tried to date;

- it maintains the reinforced glass volume at

inside the chassis;

- it makes it possible to have side by side as many frames forming the partition as will be possible with the prestressed concrete lintels with counter-jib, hence the great transparency of the facade;

- It ensures a free expansion of the partition inside the concrete bay to cancel transverse deformations; - it ensures a very high thermal tightness of the chassis at the periphery of the glass panel which limits

considerably deformations of the partition;

- It significantly reduces the bulk in thickness compared to the capacity coupa-fau;

- its aesthetic is ensured by glazing beads and the cowlings framing the glass volumes.

These advantages allow the construction of fixed or opening shuttering partitions, by adding a pivot to the ground and a pivot in the high or sliding element formed of the same profiles, or fixed or opening canopy.

All these advantages of the construction profile of the partition, as well as its expansion system thanks to the pre-frame provided with its expansion means, allow variations in the partition by replacing fixed frames with opening or sliding frames inside da the ante wire cutter partition.

The invention applied to:

- the protection of collective places to allow the complete evacuation of people in collective buildings; - the protection of places of exposure of goods or equipment of vuleur;

- the protection of places with high lisques receiving a large public;

The invention described in detail in the following text, with reference to the appended drawings given by way of nonlimiting examples, in which we have shown:

- Plate 1: front view in elevation, a provision of glass volumes in the frames making up the partition which will serve as a test in the test laboratory where we see 5 frames representing the means of holding and expansion between them and in a frame cut in two forming a partition, a group of glasses of which is intended to be exposed to the outside provided with an anti-UV interlayer assembled at the mirror shop.

As shown schematically on a small scale, elevation view on plate 1, embedded in the baia I of a concrete mun. The frames forming the firewall according to the invention consist of a peripheral support structure - board 2 - inside which

structural elements - plate 5 n ° 6 and 6 A- cooperate to maintain five leaf volumes (1 V, 2 V, 3 V, 4 V, 5 V) constituting the firebreak vitiaga. The long side of three of them 1 V, 2V and 4V is arranged vertically. The long side of the 3V volume - Plate 1 - is arranged horizontally. We climbed - plate 5 - on the whole da structure the location of the cover 9 for reinforcing glazing beads. As an example, the length of the lower glazing 3V is around 2 meters and its overhang is around 1.50 meters. For exampla, the dimensions of the repiresented partition are of the order of 3m X 3m.

This partition, made up of 5 frames, rests at the bottom on the side frame guide tube (6). It is held laterally in the upper part by a pre-frame serving as a similar slide (6) leaving a play largely sufficient to allow free vertical expansion of the chassis of the partition-board 6.

The precadrc support structure (6) is immobilized

longitudinally through sleeves by means of fastenings by bolts and described further on in figs. 15, 16, 17, 18 plancha 13.

Plancha 3 - Figures 3 at 4 represent the arrangement of the frames inside the partition where we wanted to represent the arrangement of the bottom tube (6) serving as a slide allowing lateral expansion. The intermediate means of a tube 6 A welded to the peripheral tube, for holding and expanding the lower chassis, and for sliding the upper chassis which is kept in height by the tube (6) leaving it the possibility of vertical expansion;

The board 4 -figures 5 and 6 allowing to see the possibility of intermediate expansion of two uprights with laur tube 6A laur allowing a dilation of 6mm to the linear meter and the maintenance an placed without rigid fixing.

Plate 5 shows, in section, an example of constitution of the structure of the fire wall. She has a profile made up of two folded sheets (10 at 11) - previously protected against corrosion - insulated or

felt padding (1) with very high resistance and thermal insulation glued by a non-flammable and insulating glue.

Between these profiles, we have placed spacers

(2) in rigid material with high thermal insulation coefficient. These profiles assembled by means of a set of rods (8) passing through the thermal break spacers (2) welded to the profiles.

Alternatively, the rods (8) are replaced by blind rivets arranged in the same way through intermediate spacers.

Plate 5 also shows, in cross-section, a first coveraga sheet metal sheet folded substantially in the shape of a "U". It comprises a folded sheet (9) and folded back on itself, on the side of the small wing, which penetrates by pressing on the orifice of the corresponding pareclose profile (3 at 23). This hood is used for the peripheral part of your structure and the intermediate of the chassis forming the partition.

Plate 5 shows a second cover profile (11) used for the internal parts of the chassis structure. It is in the shape of a "U" of which each of the small sides is

identical and has a reinforcement ply towards the interior. The folds each rest on a bar of nigid insulation (2) then welded or riveted (8) to the cantal section (10).

Plancha 5 shows, in cross section, a glazed section (3 and 23) of cane section. It is made of drawn steel. cold formed, held to the main profile by screw buttons (4). Plate 5 represents along D of the plate 1, the bottom slide - tube fixed to the wall by a steel assembly (25, 26, 27) composed of a sheath and ankle washer bolt, represented on a larger scale on plancha N ° 13.

The multilayer group is maintained between the profiles at the glazing bead (10.23) after interposition of strips (5 at 5A) of very compact ceramic fibers or the like.

The glazed sections (23) are made integral with the peripheral structure (10) of the chassis forming the partition by screw-buttons (4) screwed into the folded sheet metal profile in the form of an "omega" strip (10) integral with the corresponding profile (11) of said structure, To avoid tilting of the glazing bead sections (3,23) by deformation under the push of the glass groups deforming under the action of fire, their assembly has been stiffened by means of sheet metal cowling (9) folded and folded over the wings and stapled to the glazing bead (3 and 23).

A strip (1), made of an extremely insulating material, is glued to the interior of said cowling and is placed on the said beaded profiles. The glass group is isolated from the glazing bead by a strip (5) of extremely insulating material glued to the glazing bead and to the profile. The strip (5) cooperates with a silicone seal (14) - plancha 5 - and terminated by an elastomeric seal (13) which completes the thermal protection seal in line with the profile and in line with the paraclose. The seal between the end of the cowlings (9) and the concrete wall I is ensured by a flat joint cover (18), glued or leveled.

Plate 6 shows in cross section, the detail according to section A and C of plancha 1 showing, on an enlarged scale, the assembly of the glass volume (16) on the periphery of the structure of the chassis forming the partition and the fitting inside the bay by a removable pareclose and fixed on the other side by a removable dauxièma pareclose, to the pre-frame fixed to the masonry wall leaving an expansion aspect protected from fire with a protective material

thermally insulating filling finished with a flat iron joint ring (18), glued or rivated. The insulation means consists of fibers with very low heat transfer efficiency. The glass volume (16) comprises an identical multilayer group consisting of at least 5 vitias.

Plancha 7 shows, in cross section, along 7 of plate 1, the assembly of two glass volumes, arranged on each side of an internal element (plate 5 n ° 9,10,11,3,23) of structure of the partition. The glass groups 16 and 20 are mounted identically to plate 5,6. The difference from boards 5 and 6 is that the amount without expansion between the two volumes visible on the board (1) at the top left, keeps the volume 1V and 2V on each side using already glazing beads cited in plunche 5 - N ° 3 and 23 isolated by insulating fiber strips (5 at

5A) silicone (14) and elastomer seal (13) on the plancha 5.

The profile ensuring the maintenance of the volumes inside the partition is of the same composition and the same size. It demonstrates the judicious use of the provision of removable glazing beads 3 and 23 for maintaining the glass volumes or for maintaining the partition with the guide tubes (6 at 6A), and expansion of the partition.

We thermally protected the glazing beads (3 at 23) by means of a cover profile 9 - plate 5 - stapled on case glazing beads. A strip of thermally insulating bonded material has been bonded to the inside face of these cowlings. The glazing beads 3 and 23 are nigidified by this staple cover.

Plate 8 schematically shows a transverse - vertical section along D in fig.1. It presents cn the lower part 6 A of support and lateral guidance of the horizontal element of the plancha 2, the front frame of the partition.

Boards 8 and 9 show an axample of means ensuring both the immobilization function of the partition, in the bay, vertical and horizontal according to 3 and E in Figure 1, by one of its vertical uprights or horizontal crosspiece as well free vertical or horizontal expansion of said partition. Planks 5 and 6 surround the partition fitted with a peripheral pareclose with a piofilé insulated by a fine Gande of about 3mm, held in profile by das self-piercing screws. The note of this glazing bead is to keep the partition tight to the front frame.

The precadrc composed of a tube is offset and kept at a distance from the masonry wall by a plank 73 figures 15 and 16 - expansion guide in case of temperature rise of the tube, ccci allows a displacement of the tube vars the masonry wall in the event of Lesoin of its displacement in extension of dilation. The oblong hole (board 13 - figure 18) in which the sleeve (25) is kept - board 13 - figures 15,16,17 - tightened with a button, allows a longitudinal expansion of the precadre tube. The button is screwed to the steel dowel (27) inserted in the masonry, figure 17 - plate 13.

As the frames making up the firewall are not fixed on either side, they can expand straight in the horizontal direction by sliding along the slide frame

lower and upper plank 2.

On plate 11, we have shown diagrammatically four locations of partitions arranged side by side in a perch.

No partition is secured to the concrete wall by fasteners. The spaces between the frames forming the partition and the bay, as well as the other peripheral spaces, are filled with a mattress of loose fibers (15- board 5) which are very insulating in theory. A rectangular tube is welded to the peripheral tubes fixed to the masonry wall.

This tube holds several long partitions in place - plancha 11 - without limit: neither in length nor in height - board 12.

The two partitions are separated from themselves and from the guide tube so as to allow both to keep them in place when cold, and sufficient space allowing their free expansion (7) when hot - board 8 and 9.

It is therefore possible to affix as many lateral partitions at as many vertical levels to paitii as long as he has respected the same pose and dilation lagla (7).

On plate 10, we have schematically mounted four partitions in height in the same bay. They are mounted in the same way as those of plate 12, but in the veitical direction, see plate 5 for their lower part; Plate 8 representing the top of the first partition at the bottom and the bottom of the partition at the next level at plancha 6: the top of the partition on the fourth level. The limit of the number of chassis according to the invention is that of the length and the height da bay that it is possible to achieve with a minimum deflection, for example with lintels in prestressed concrete

counter-jib, and thick masonry posts or walls capable of supporting concrete beams

piécontiaint.

The space reserved for expansion carries the number 7 on boards 3, 4, 6, 8, 9, 10 and 13.
