Description

DESCRIPTION

Façade opening frame

Technique sector.

The present invention is applicable in the construction sector and more specifically in the finishing of façade holes intended for the assembly of windows or enclosures.

Prior state of the art

Currently, in the construction sector, the use of enclosures, such as doors or windows, for closing façade holes is widely known.

These enclosures generally have a perimeter frame that is fixed to the work and on which one or more sheets of the enclosure itself are mounted.

In the case of metal carpentry enclosures, the use of frames with thermal break is widely known, which are basically made up of two metal profiles, one inside and the other outside, joined together by an intermediate, non-metallic profile with a low coefficient of thermal transmission.

However, in those cases in which the metal carpentry is mounted on a façade hollow frame, the use of an enclosure provided with a frame with a thermal bridge break does not completely solve the problem of thermal transmittance from the outside to the inside. This is due to the fact that other elements commonly used in the assembly of these enclosures, such as the aluminum flashing profiles, used to cover the transition area between the metal enclosure and the wall inside the room or home, establish a contact Directly with the metal material of the frame, there is no element between them that establishes the breakdown of the thermal bridge between the exterior and the interior.

Therefore, the technical problem that arises is the development of a façade hole frame with suitable characteristics to prevent thermal exchange, between the exterior and the interior, from said frame to the elements of the enclosure, such as the frame itself. frame of the enclosure, or the flashing profiles, mounted on said frame.

Explanation of the invention.

The façade opening frame object of the present invention has technical characteristics that allow the problem raised above to be satisfactorily solved.

This façade opening frame is suitable for mounting an enclosure in a façade opening and comprises a metal sheet box provided with two side walls, an upper wall and a lower surface, and is open on the two remaining faces, oriented towards the outside and towards the inside of the façade hole.

According to the invention, said sheet metal walls comprise at the end corresponding to the inner face of the frame an "L" extension that projects laterally from the perimeter of said face and defines a perimeter housing in which a first metallic profile is housed. of a frame frame, composed of: said first metal profile, an intermediate profile of a material with low thermal transmittance, fixed to said first profile and protruding in a frontal direction from the said perimeter housing of the frame box, and a second profile metal fixed to the intermediate profile and that forms a support and fixing area of the elements of the enclosure to the frame, such as the fixed frame of the enclosure and the flashing profiles.

The projecting arrangement, in a lateral direction, of the aforementioned "L" extension enables the mounting of the frame of the frame without reducing the section of the box and therefore the width of the opening delimited by said frame.

The intermediate profile of the frame of the frame breaks the thermal bridge between the first metal profile that is in contact with the metal box and therefore with the outside, and the second metal profile facing the interior of the room and on which the different elements of the enclosure are fixed, such as the fixed frame and the flashing profiles.

According to the invention, the intermediate profile of the frame of the frame is made of polyamide, which is a material with low thermal transmittance.

According to the invention, the walls of the box comprise on its outer face some perimeter fins that form a stop for mounting the frame in the façade hole.

Preferably said perimeter fins are formed by folds defined at the outer ends of the walls of the box and are located in an intermediate zone of said walls.

The upper and lower walls of the box have at their outer end folds that define a gutter oriented towards the lower zone.

Brief description of the content of the drawings.

To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, the present specification is accompanied by a set of drawings in which, by way of illustration and not limitation, the following has been represented:

- Figures 1 and 2 show respective views of an example of embodiment of the frame for a façade opening, according to the invention, seen from its outer face and inner face respectively.

- Figure 3 shows a front view of the frame of the previous figure, seen from its outer face.

- Figure 4 shows a profile view of the frame of the previous figures sectioned along the vertical plane A-A 'referenced in figure 3; and an enlarged detail of the frame section of the frame mounted on the perimeter "L" flange of the inner end of the frame box.

- Figure 5 shows a view of the frame, analogous to that shown in figure 4, and in which the assembly of an enclosure on the frame of the frame can be seen.

Detailed exposition of embodiments of the invention.

The facade opening frame shown in the attached figures comprises a metal sheet box (1), in this specific case made of galvanized steel, provided with two side walls (11), an upper wall (12) and a lower wall (13 ), the two remaining faces of the box being open towards the outside and towards the inside of the façade hole.

The walls (11 - 13) of the box (1) comprise at the end corresponding to the inner face of the frame an "L" extension (14), which defines a perimeter housing in which a frame (2) is mounted. of recerco.

As can be seen in the enlarged detail of Figure 4, said recirculation frame (2) comprises: - a first metal profile (21) housed and fixed in the perimeter housing defined by the aforementioned "L" extension (14) of the box (1), - an intermediate profile (22) made of a material with low thermal transmittance, fixed to the first metal profile (21) and protruding in a frontal direction from the aforementioned perimeter housing of the box (1) and a second metal profile (23) fixed to the intermediate profile (22).

In this embodiment, the intermediate profile (22) is made of polyamide and, as shown in figure 5, performs the thermal bridge break between the first metal profile (21), in contact with the metal box (1), and the second metal profile (23) on which the fixed frame (31) and the flashing profiles (32) of an enclosure (3) are mounted.

The walls (11, 12, 13) of the box comprise on their outer face some perimeter fins (15) forming a stop for mounting the frame in the façade hole.

Additionally, the upper and lower walls (12, 13) comprise at their outer end some gutters (16) oriented towards the lower zone.

Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the elements described may be modified, as long as this does not imply an alteration. of the essential characteristics of the invention that are claimed below.
