Description

Technical field to which the invention relates

The present invention relates generally to the field of carpentry.

It relates more particularly to a carpentry structure comprising a frame provided with at least two juxtaposed panels of the type glazed panels and / or non-glazed filling panels.

Technological background

Some building facades are equipped with a carpentry structure, interposed between an interior volume and an exterior volume, comprising a frame formed by an assembly of uprights and crosspieces, which constitute quadrangular framing structures used for the reception of glazed panels or non-glazed filler panels.

This type of carpentry structure can be an isolated assembly or composed of several assemblies to constitute a facade.

Each upright and cross member of the chassis comprises a section of a U-shaped rebate for receiving a border of one of the panels, consisting of:

- a rebate background,

- an inner wing intended to be oriented towards the interior volume of the building, and

- an external wing intended to be oriented towards the exterior volume of the building.

The outer wings of the rebate sections are made in one piece with at least part of the rebate bottom, and they have a support joint on the associated panel.

On the other hand, as a general rule, the inner wings of the rebate sections are constituted by a removable attached glazing bead, provided with a support joint on the associated panel, allowing the installation of said panel (or its removal) by the inside the building, for accessibility reasons.

In some cases, for areas that are not accessible or difficult to access from the inside, the removable glazing beads are provided at the level of the outer wings of the rebate sections.

This can be the case for example for an area of the facade against which an internal staircase is provided or an area for structural work.

For this, the solution usually used consists in adding a rebate reverser which requires the addition of external glazing beads in the clear vision of the frame.

However, in such a configuration, the presence of external glazing beads, which only equip part of the framing structures, harms the aesthetic homogeneity of the whole.

The description which follows with reference to the accompanying drawings, given by way of nonlimiting examples, will make it clear what the invention consists of and how it can be carried out.

In the accompanying drawings:

- Figure 1 is a schematic front view, illustrating a carpentry structure according to the invention formed of a plurality of quadrangular framing structures;

- Figure 2 is an enlarged view of part of Figure 1 which shows one of the quadrangular framing structures of the carpentry structure according to the invention, front view.

- Figure 3 is a sectional view along the cutting plane 3-3 of Figures and 2;

- Figure 4 is a sectional view along the cutting plane 4-4 of Figures and 2;

FIG. 5 is an enlarged view of detail A in FIG. 4.

- Figures 6 to 13 are sectional views illustrating the main stages of the installation of a panel in the quadrangular framing structure illustrated in Figures 2 to 5.

The joinery structure 1 illustrated in FIGS. 1 to 5 is intended to be interposed between an interior volume I of a building (for example a stairwell or a building structure component, at the level of which the disassembly of the panels from the interior of the building is not possible) and an exterior volume E.

This joinery structure 1 comprises a frame 2 which is formed by an assembly of uprights 3 and crosspieces 4, to constitute a plurality of juxtaposed quadrangular frame structures 5 each receiving a panel 6 (of the glass panel or filling panel type) .

In Figure 1 there are shown four quadrangular framing structures 5a, 5b, 5c and 5d, juxtaposed vertically, and each receiving a panel, respectively 6a, 6b, 6c and 6d.

In the following description, the indices a, b, c, d ... refer to the quadrangular framing structure 5a, 5b, 5c, 5d ... which is concerned.

The joinery structure 1 can comprise fewer juxtaposed quadrangular framing structures; but very generally it will include more than four, juxtaposed vertically and horizontally, depending on the surface to be equipped, in the case of building facade construction in particular.

The uprights 3 and the crosspieces 4 of the quadrangular framing structures 5 each comprise a rebate section 7 with a U-section, for the reception of an edge of one of the panels 6, this rebate section 7 comprising a bottom rebate 71, a first wing 72 intended to be oriented on the side of the interior volume I, called the interior wing 72, and a second wing 73, intended to be oriented on the side of the exterior volume E, called the exterior wing 73.

The inner wing 72 and the outer wing 73 have support seals on the panels 6, to wedge and seal the latter.

In general, the quadrangular framing structures 5 are arranged to allow the installation (or removal) of their associated panels 6, by the interior volume I.

For this, at least one of their inner wings 72 is constituted by an attached removable glazing bead (and preferably their four wings 72 are constituted by such an attached removable glazing bead).

This is the case here for the quadrangular framing structures 5a, 5c and 5d, fitted with panels 6a, 6c and 6d (which are all glass panels here).

On the other hand, in certain cases, the installation (or removal) of the panels 6 may prove to be difficult to achieve by the interior volume I, and the carpentry structure 1 is arranged to carry out this installation or removal by the exterior volume E, at using a stripping technique on one or two sides, and this while proposing masses of uprights and crosspieces identical or similar to those of the uprights and crosspieces of contiguous quadrangular framing structures.

This is the case here for the quadrangular framing structure 5b which is located just in front of an internal staircase B and which is equipped with panel 6b (here in the form of a filling panel).

For this, as can be seen in FIGS. 3 to 5, the peripheral rebate 7b of the quadrangular framing structure 5b comprises a section 7b1, the outer wing 73b1 of which is constituted by a removable attached glazing bead (this is in the occurrence of the outer wing of the lower cross member of the quadrangular framing structure 5b).

In addition, the outer wings 73b2, 73b3 and 73b4 of the three other rebate sections 7b2, 7b3, 7b4 of said peripheral rebate 7b (that is to say the outer wing of the rebate sections of the upper cross member and the two lateral uprights of the quadrangular framing structure 5b) have an identical structure constituted by (FIG. 5):

a base part 8 produced in one piece with at least part of the associated rebate base 71 b2, 71 b3, 71 b4, comprising a free end 9, and

- An extension part 10, comprising one end 11 projecting from the end 9 of said base part 8, which extension part 10 is constituted by an added profile, fixed on the associated rebate base 71 b2, 71 b3, 71 b4 and / or on said base part 8, by fixing means, in this case a screw 12 (shown diagrammatically in FIGS. 3 to 5).

In the embodiment illustrated in the figures, the peripheral rebate sections 7b comprise a rebate bottom 71b consisting of two metal profiles, one inside 13, for example made of aluminum (oriented towards the side of the interior volume I), and l 'other exterior 14, for example aluminum (oriented on the side of the external volume E), assembled by a thermal break profile 15, for example plastic.

This assembly between the profile 15 of thermal break and the interior 13 and exterior 14 profiles can be produced in a conventional manner by systems of the tenon-mortise type.

On the side of the interior volume I, the four rebate sections 7b comprise an interior wing 72b which is in the form of an L-shaped profile comprising a base wing 16 extended by a side wing 17.

The base wing 16 is assembled with the inner profile 13 of the rebate base 71b by means of a fixing screw 18 (illustrated schematically in Figures 3 to 5).

For its part, the free end of the lateral wing 17 has a groove 20 receiving a seal 21 on which the glass panel 6b bears.

On the rebate sections 7b2, 7b3 and 7b4, the base parts 8 of the outer wings 73b2, 73b3, 73b4 consist of a one-piece extension of the outer sections 14 of the rebate bottoms 71 b2, 71 b3 and 71 b4.

As detailed in FIG. 5, the free end 9 of these base parts 8 includes an end return 22 which is oriented towards the associated panel 6b; and the extension part 10 is in the form of an L-shaped profile, a first wing 10a of which abuts against the rebate base 71b, and more particularly against the outer profile 14, and whose second wing 10b comes into abutment against said end return 22 of the base part 8.

This second wing 10b extends parallel to the base part 8, in a plane offset towards the associated panel 6b, relative to said base part 8; and its projecting end 11 forms an end angle 23, L-shaped section, with the end return 22 of the base portion 8. This end angle 23 serves to support a seal 24 bearing on the panel 6b.

This support seal 24 is a seal of the stuffing type, comprising a groove 24a for its embedding on the projecting end 11 of the extension part 10.

A first part of this seal 24, located on one side of the groove 24a, is intended to be positioned between the panel 6b and said projecting end 11 of the extension part 10.

Another part of this seal 24, located on the other side of the groove 24a, is intended to come to cover the external face of said projecting end 11, up to the end 9 of the base part 8.

The assembly screw 12 serves as a connecting member between the first wing 10a of the extension part 10 and the external profile 14 of the rebate base 71b.

On the rebate section 7b1, the removable glazing bead 73b1 constituting the outer wing consists of a section of section with a generally L-shaped section comprising (FIG. 3):

a first wing 25 provided with means for its removable fitting onto the external part 14 of the rebate base 71 b1, and

- a second wing 26, the free end 27 of which serves to support a seal 28 for supporting the panel 6.

This free end 27 of the second glazing bead wing 26 is in the form of an angle iron, with an L-shaped section, identical to the end angle iron 23 of the outer wing 73b2, 73b3, 73b4 of the rebate sections 7b2, 7b3, 7b4.

The support joint 28 is identical to the abovementioned joint 24 which equips the outer wings 73b2, 73b3, 73b4 with the rebate sections 7b2, 7b3, 7b4.

This seal 28 is a seal of the stuffing type comprising a groove for its embedding on the end angle 27 of the second wing 26 of glazing bead.

A glazing bead 73b1 is thus obtained, the aesthetics of the outer face of which approximate the aesthetics of the juxtaposed outer wings 73b2, 73b3, 73b4 formed from the base part 8 associated with the extension part 10.

The profiles 13, 14 and 15 which form the rebate bottom 71b also serve as a rebate bottom for the juxtaposed quadrangular framing structures lower 5a, upper 5c and lateral 5e and 5f (FIG. 4).

At this level, the inner wings of the rebate sections are constituted by removable glazing beads 72a, 72c, 72e, 72f provided with means 30 for their removable interlocking on the interior profiles 13 and with a seal 31 for support on the panel. 6a, 6c, 6e and 6f associated (for example glass panels).

The outer wings are constituted by a one-piece extension 32 of the outer profile 14 of the rebate bottom.

This monobloc extension 32 comprises an end housing 33 open in the direction of the associated panel 6a, 6c, 6e, 6f, adapted to receive a support joint 34.

This monobloc extension 32 is identical to the base part 8 of the outer wing 73b of the rebate bottom 7b2, 7b3, 7b4. It extends on the other side of the outer profile 14, with respect to this base part 8, symmetrically with respect to the latter.

As described above, in the embodiment illustrated in FIGS. 3 to 5, the peripheral rebate of the quadrangular framing structure 5b comprises a rebate section 7b1, corresponding to the lower crossmember, whose outer wing 73b1 is constituted by a removable attached glazing bead, and three rebate sections 7b2, 7b3, 7b4 of which the outer wing 73b2, 73b3, 73b4 is constituted by a base part 8 associated with an extension part 10.

In alternative embodiments, the corresponding glazing bead can be fitted to the upper cross member or even to one of the lateral uprights of the quadrangular embedding structure 5b.

Also in an alternative embodiment, the peripheral rebate of the quadrangular framing structure 5b may comprise two rebate sections, the outer wing of which is constituted by a removable attached glazing bead, and two rebate sections of which the outer wing is constituted by a base part associated with an extension part.

In the latter case, the two rebate sections of which the outer wing is constituted by a base part associated with an extension part constitutes either an angle of the framing structure, or the two uprights or the two cross members of the structure coaching.

Starting from the joinery structure 1 illustrated in FIGS. 1 to 5, whose quadrangular framing structure 5b is devoid of its external glazing bead 73b1, its external seals 24 and its panel 6b, the mounting of this panel 6b s' preferably performs according to the succession of steps illustrated in FIGS. 6 to 15.

The panel 6b (for example an opaque sandwich type filling panel) is embedded, from the external volume E in the peripheral rebate 7b by a stripping technique, that is to say by gripping one of its lateral edges in the rebate of one of the lateral uprights (FIG. 6), then by straightening it (FIG. 7) and by refocusing it (FIG. 8) relative to the two lateral uprights.

The panel 6b is then in abutment against the seals 21 fitted to the inner wings 72b (except possibly against the seal 21 of the upper cross member - Figure 9).

The lower edge of the panel 6b is then mounted on lower shims C (Figure 10) to ensure its correct positioning in height.

On the interior side, the panel 6b is then in abutment against the four interior wings 72b, by means of their support joint 21.

On the outside, its peripheral edges are opposite the ends of the outer wings 73b2, 73b3, 73b4 of the lateral uprights 3 and of the upper crosspiece 4.

Then, the external glazing bead 73b1 is put in place at the level of the lower cross member 4 (FIG. 11).

Finally, the timing and final sealing are carried out by means of the stuffing joints 24 and 28 positioned on the glazing bead 73b1 and the end angles 23 of the outer wings 73b2, 73b3 and 73b4 (Figures 12 and 13).

Seen from the outside, an assembly is obtained comprising homogeneous or relatively homogeneous metallic masses between the various juxtaposed quadrangular framing structures, which include external or internal glazing beads.

In the case of an aforementioned variant embodiment, the stripping laying technique is adapted as a function of the rebate sections devoid of glazing beads.
