Abstract

The invention concerns a universal profile for a bay frame applicable to supports, splays and covings, particularly for the external covering of these bays. It is characterised in that it has several longitudinal cells 2, 7 delimited by walls having substantially the same thickness; an element 8 corresponding to the frame with all the grooves ensuring fluid-tightness with the leaf; a bearing surface 9 whose edge 16, 17 can receive the fitting, by simple pressure, of a batten 10 parallel to the external wall and extending towards the exterior of the perimeter of the bay, the said bearing surface 9 being provided such that it may be cut off by at least a defined length while still having, on its edge, a means of fitting, by simple pressure, the said batten 10. Application of bays of buildings which are insulated.

Description

Technical area
The present invention relates to a universal ssel profile for bay frame applicable on supports, sashes
and arches usable, in particular, for the external covering of these bays.

Problem
It is necessary to reinforce the insulation of existing buildings by applying insulation externally. This causes an extra thickness and obliges to review the protection of the cuts of these coatings at the level of the bays.
In the same operation, we also frequently change the berries, we could consider redoing
the window frames, especially window frames, with
masonry and in particular poured concrete. It would be
expensive and the invention provides a more economical solution
and flexible using a particular profile.

Statement of the invention
The profile of the invention is characterized by
the fact that it has - several longitudinal cells delimited by walls having substantially the same thickness - an element corresponding to the frame with all the grooves ensuring sealing with the opening - a shelf whose edge can receive adaptation, by simple pressure , a slat parallel to the outer wall
and extending outward from the perimeter of the bay,
said tablet being intended to be amputated by at least
a defined width by always presenting, on its edge,
a means of adaptation by simple pressure, of said slat.

 To facilitate its attachment to the walls of the existing bay or to serve as an anchor for the heads of aboulons, grooves with lips are provided on the faces of the profile to be applied to the wall and more precisely to the walls of the frame. closer together than the bottom walls of said groove.

 An important feature of the invention intended to allow the adaptation of the profile to several splay depths and to several thicknesses of insulating coating consists in providing that the edge of the shelf and its partitions located at the places where it can be amputated, have a tail groove. dovetail where the slat can be stapled by complementary projections.

 Another important feature is that the section of the shelf is identical for the four sides of the bay frame and that the adaptation is made by the slat. Indeed, it is the slats which adapt this profile to its support position, arching, tables.

 The profile of the invention can be made of any material. In general, it will be made of extruded polyvinyl chloride, but it can also be made of light alloy. It is worked like joinery elements in these materials. The slat has staples which are fixed in a suitable way in the dovetails of the ends of the shelves which gives them a certain elasticity making it possible to press on the external walls. and to ensure sealing as will be explained below in more detail.

 The installation of ventilation provision in the profiles is easy, in particular to ventilate the air space of facade complexes.

 In fact the tablet has two thicknesses of planar material, practically parallel, which are connected by longitudinal partitions at the places where said tablet must be amputated. These partitions have dovetail grooves for the adaptation of the slats.

Each partition therefore corresponds to a different shelf width which allows, by sawing at this location to provide the desired shelf width.

 The invention will be better understood with the aid of the description below which gives two non-examples.

limiting of practical realization which are illustrated by the attached drawings.

Brief description of the figures
In these drawings
Figure 1 shows a cross section of a profile of the invention in its original version with the adapted end strip.

 FIG. 2 represents the same profile as that of FIG. 1 but which has been cut by a certain width, at the level of an intermediate partition, in order to be able to adapt the end batten thereto.

 Figure 3 is a cross section of a arch or side walls of a frame of a construction which has been externally insulated and which comprises the profile of the invention.

 Figure 4 is a cross section similar to that of Figure 3 but relating to a support.

Description of some embodiments
Profile (1) (Figure 1), (102) (Figure 2), ~ (103) (Figure 3) or (104) (Figure 4) has several cells such that (2, 3, 4, 5, 6 , 7) which determine walls of substantially # the same thickness # r, which is a desirable technique in extrusion manufacturing.

The profile (1, 102, 103, 104) essentially breaks down into an element (8) which has the shape of a frame and a shelf
(9ì whose end receives a slat (10) or (11) parallel to the outer wall. Of the wall (12>. The cells such as (7) are separated by partitions such as (13, 14) which- comprise a dovetail deformation intended to receive by adaptation by stapling the slat (10) or (11) which has, for this purpose an elastic staple (15) of corresponding profile.

The tablet (9) is intended to be amputated in (16) or
(18) flush with one of the partitions (13) or (14) so as to be shortened. Each of these partitions (13) or (14) having a dovetail groove, it is always possible to adapt the slat (10) or (11) to it.

 The frame element (8) has all the usual grooves (16, 17, 18) for this type of profile in order to be able to adapt seals therein or to collect leakage or condensation water. One of these cells includes moldings such as (19) in order to be able to slide a stiffener (20) there which bears thereon and stiffens the assembly.

We provide on the faces of the profile (1) in front
apply to the wall, grooves (21, 22) with lips such as (23, 24) closer together than the bottom walls of said grooves.

In FIG. 3, the profile (103) has been adapted -
to a wall (25) at the location of a bay (26). The wall (25) has been covered on the outside with a layer of insulation
(27) which is held by a frame (28) itself recou
green cladding (29). To seal the
batten (11) has a rim (30) which strongly supports
on the cladding (29).

Naturally, the profile (it) can appear differently and in the case of an arch, it can be provided that the cladding (29) comes to cover it externally.
to avoid # water infiltration.

In Figure 4, there is shown the profile (104)
on a wall support (25) covered externally with a
layer of insulation (27) maintained by uprights such as
(31) and spacers such as (32). A batten such
that (33) is used to support the cladding (34) and to maintain
a grid (35) so as to ensure air circulation
following the arrows (36) and (37). The profile (104) is supported
on the old concrete support (38) by means of shims (39).

 We will not show here the details of joinery and carpentry intended to support the profile of the invention itself because these joinery, carpentry depend on the cases of species.

We will not insist on the realization either
shelves and entablatures inside, which however
been shown in the drawings for the same reasons
and by the fact that these are not part of the invention.
