Abstract

System for the realization of metal frames for sliding doors and windows with improved thermal insulation. It is a system composed of the following elements; an interior aluminum profile (1), a triple-chamber central profile made of heat-insulating material (pvc, polyamide reinforced with fiberglass, etc.) (3), and an aluminum exterior profile (2). The assembly or assembly of the previous components is carried out by sliding and its fixation is obtained by mechanical closing, adhesives or other procedures. The invention solves the problem of thermal insulation of the metal frames of windows and sliding doors, both in the central area and in the interior areas of the rolling carriages (4), this last feature providing novelty to what is currently known.

Description

System for the realization of metal frames of sliding windows and doors with thermal insulation improved.

Technical sector

The invention falls within the technical sector of aluminum carpentry, more specifically in the manufacture of profiles for window frames and opening doors slide.

State of the art

Composite profiles with interruption of thermal bridge used in metal carpentry are already known. Generally these profiles are made up of a profile interior and exterior both extruded aluminum, joined by means of a heat-insulating material, in the form of bars or profiles located in the central part of the interior and exterior profiles. This commonly used procedure, get the interruption of the thermal transmittance of aluminum profiles, for application in swinging or practicable opening systems, but does not solve the problem presented by the opening frames sliding since the thermal transmittance interruption of aluminum profiles are achieved in the central part of the profile and not in the areas of the raceways, since these areas are exposed to the outside environment in half the width of the window or door. The deficiency described above, prevents allowing its use within the current values thermal transmittance of metal frames, required by current European regulations, in terms of savings of energy and building.

Description of the invention

To remedy the inconveniences mentioned in In the previous section, the invention proposes a connection system of the profiles, interior and exterior by means of a single profile triple chamber intermediate and thermo insulating material, which prevents the thermal transmittance of aluminum profiles both in the central part as in the raceways together, thus obtaining considerable advantages, such as reduction of the assembly time of the profiles, as in their cost of production.

Thus, three systems are used in this system. profiles, two extruded aluminum profiles, interior profile (1) and outer profile (2) and a single intermediate multiple profile plastic material chambers (3) that isolates the profiles, interior and exterior in its entirety included the lane areas of rolling (4).

Interior and exterior profiles (1), (2) they have guides (6) for the correct alignment and fixation of the intermediate profile (3), which in turn includes the slits (9), and the outgoing (10).

The interior (1) and exterior (2) profiles they have tubular (5) for assembly with 45 ° cut together using brackets, they can also be used with screw holders for assembly with 90 ° cut and joined by screws self-tapping

Another important feature of the system is that the low thermal transmittance values obtained by the resulting joint profile, allow its use within latest European regulations on energy saving and edification.

The present invention relates to a new procedure for thermal insulation of rails rolling and profiles, exterior and interior in the frames of aluminum for sliding windows and doors, providing sensitive characteristics of novelty and activity Inventive to what is currently known.

Description of an embodiment

For the description of the assembly of the resulting frame profile we take as reference the numbering of the
Figure 3

By sliding coupling and using the projections (6) and (8) of the profiles (1) and (2), the projections (10) and cavities (9) of the intermediate profile (3) by way of guide, you get the resulting frame profile, which after aligning its ends proceed to the closing of the hammers (7) by mechanical procedure

Claims (2)

1. System for the realization of metal window frames and sliding opening doors with improved thermal insulation. Obtaining these from the union of two aluminum profiles, one inside (1) and another outside (2) by means of a triple chamber profile made of thermo insulating material (3) which is located between the central inner part and the raceways ( 4) of the aluminum profiles (1) and (2) reduces the thermal conductance of the frame profile resulting from the union of the three profiles; characterized in that the aluminum profiles, interior (1) and exterior (2), incorporate housings and their central part (8) and guides in the raceways (6) that allow their union by sliding with the intermediate profile (3) incorporating the latter in turn the grooves (9) and the projections (10) that facilitate its placement. Finishing the assembly by closing the hammers (7) by mechanical systems. 2. System for the realization of metal window frames and sliding opening doors with improved thermal insulation; characterized in that the raceways (4) of the inner (1) and outer (2) aluminum profiles are completely isolated from the outside environment, achieving a low thermal transmittance metal profile.
