FR2584128A3 - Frame for windows and curtain walls having uniform fixed and opening casements - Google Patents

Abstract

Frame leaf to be incorporated in a fixed casement or in a curtain wall, characterised in that the glazing 5 is placed by adhesive bonding on the front face of the structural section of the leaf 4, the latter being recessed from this glazing, except for the flat stepping 8 for supporting/adhesive-bonding the external glass.

Description

Uniform window frames and curtain walls.

Certain architectural designs require that fixed and opening glazing have no aesthetic difference between them between the facades.

Both the architecture and the physics of the building (condensations, thermal diffusion and phonic transmissions) require that these frames can be executed using the widest range of present and future technologies with regard to both glazing and building techniques. '' waterproofing, joints and drainage, incorporation into conventional structures or curtain walls and the choice of materials constituting the window (wood, synthetic materials, metals or compounds of such materials).

The research which led to the present invention was mainly oriented towards a leaf design incorporating into the frame (either conventional frame, or frame integrated in a curtain wall structure) so that the whole presents, in faça de, lines uniforms and similar plans while reducing the opaque surface of the whole to the benefit of the useful glass surface of the bay in question.

If, in general, the term "facade" means the facade seen from the outside, nothing prevents the reverse system from being applied where the dull "facade" would designate the wall seen from the inside of the building.

The chassis thus formed are designed to be fitted with accessories and improvements similar to those of conventional chassis (thermal improvements), hardware stores, etc.).

The windows of the windows are applied to the outside of the structural profile of the window. This application is done without a barrier using the techniques known as "Structural glazing #.

According to the invention, the glazing is placed by gluing on the anterior face of the structural profile of the leaf, the latter being set back from this glazing, except for the only flat supporting step of bonding of the external glass.

In order to better highlight the characteristics of the invention, some exemplary embodiments are described below without any limiting character and with reference to the appended drawings in which:
Figure 1 shows a schematic section
fixed window according to the invention;
Figure 2 shows a schematic section of a
opening window according to the invention;
Figures 3 and 4 show a pos application
aluminum sible with thermal break;
Figures 5, 6 and 7 show variants of
Figures 3 and 4.

In FIG. 1, the window frame 1 for fixed window (glazed or paneled 2) has a section seen on the front (x) identical to the section (x) of the window frame 3 for movable leaf 4 provided with a glazing or panel 4.

This can be applied to any opening system including sliding leaves or to combined movements (oscillating, various opening, sliding, translational, etc.). Similarly, in these figures 1 and 2, the glazing or paneling planes are similar, except for the variants, between striking joints 6 and 7.

The total or partial absence of impact on the facade side is a possible variant.

The important characteristic allowing the realization of the system is the assembly of the glazing or panel 5 in the wing 4. Indeed, this assembly is done without applying the conventional technology which embeds the glazing 5 between two strikes of the leaf, one of these strikes generally, but not necessarily, consisting of a barrier.

In the current system, the glazing or panel 5 descends in front of the leaf profile 4 so as to only take support from a lower step 8 of this leaf 4.

The system according to the invention uses the technique of bonding the glass (panel) to the leaf profile by means of bonding joints 9 (silicone).

This technique is known by the term "Structural
Glazing ".

Although the system according to the invention is made possible by application of the technique known as "Structural
Glazing "at the door, the simultaneous advantages of this application to the window are multiple, which makes them characteristic and new. These advantages are in particular: - appearance identity in front both for the parties
fixed only for mobile leaves; appearance free of joins and plan changes
resulting from conventional solutions showing the dormant
and the leaf; the system affecting the leaf alone makes it possible to be
incorporated into a frame frame system or
in the structure of a curtain wall; the assembly of the glass to the leaf is, besides the colla
age, reinforced in closed position by application of
glass against a striking joint 7 (for chassis
with striking and curtain walls with joint cover profile
exterior), which meets most descrip
usual tions; drainages, double or triple joints apply
as for classic windows; any thermal break may apply to
alone sleeping; the reduced dimensions and reliefs (x) of the faces of
chassis (front) as well as total waterproofing
seals (9) act in the direction of reduction
heat conduction and pho transmission
nique, a reduction in opaque surfaces and, this,
for the benefit of glass surfaces, solar gains and
the luminosity; ; simplification of the leaf for which the baffles
are superfluous (as well as thermal breaks); - the surface appearance of the metal exposed on the facade can
differ from that of structural profiles.

Claims (3)

 1 - Frame leaf to be incorporated in a frame or in a curtain wall, characterized in that the glazing (5) is placed by gluing on the front face of the structural profile of the leaf (4), the latter being set back from this glazing, except the only flat redent (8) for supporting / bonding the exterior glass.  2 - Leaf according to claim 1, allowing to respect an identity of lines between fixed parts (1) and opening parts (3) while reducing the frame surfaces exposed on the front due to the departure of the glazing (5) in front of the profile leaf (4).  3 - Window sash, curtain wall or similar, characterized in that the identity of lines (x) between the front faces of the fixed sash (1) and sashes (3) is obtained by eliminating the conventional striking of the sash and positioning the glazing (5) between the structure of the opening (4) and striking the frame (3).
