Abstract

The object of the utility model is a fire-resistant aluminum profile of a warm system, especially for doors or windows. The fire-resistant aluminum profile of the warm system has an external profile (1) and an internal profile (2), connected with each other by thermal separators (3), forming a thermal chamber (4) between them. The connected sections form three-chamber profiles. The outer profile (1) has an outer chamber (5), and the inner profile (2) an inner chamber (6). The thermal chamber (4) and the outer chamber (5) and the inner chamber (6) have fire retardant material (7) inside. The cross-section of the outer chamber (5) and the inner chamber (6) has the shape (8) of a rectangle with two opposite corners (9) selected, adjacent to the outer wall (10) of the outer profile (1) and the inner profile (2).

Description

Pattern description

The subject of the utility model is a fireproof aluminum profile of the warm system, especially for doors or windows.

The aluminum profiles of the frame or door leaf of the warm system consist of external and internal sections, connected with each other by thermal breaks. The interconnected sections form three-chamber profiles. The external section has an external chamber, and the internal section has an internal chamber, and the chamber formed by joining the external and internal sections with thermal breaks is a thermal chamber. Due to the multi-layer structure, the profiles have a low heat transfer coefficient. To increase the thermal insulation coefficient, the thermal chamber and / or the outer and inner chambers of the profile are filled with insulating material. The insulating material, once in place, prevents air migration and heat transfer. Profiles are known in which the cross-section of the inner or outer chamber is a rectangle or a rectangle with one corner selected. Such a shape of the chambers means that the insert inside the chambers may fall out during the melting of the profile during a fire.

The purpose of the utility model is to develop a profile shape in which the fireproof insert will adhere to its structure and will remain in place for a longer period of time during the melting and firing of the profile.

The fire-resistant aluminum profile of the warm system, according to the utility model, has an outer section and an inner section, connected with each other by thermal breaks, forming a thermal chamber between them. The interconnected sections form three-chamber profiles. The outer section has an outer chamber, and the inner section has an inner chamber. The thermal chamber and the outer chamber with the inner chamber have fireproof and / or insulating material inside. The cross-section of the outer chamber and the inner chamber is rectangular in shape with selected two opposing corners adjacent to the outer wall of the outer section and the inner section.

Such a construction of the external section and the internal section of the profile causes that the fireproof insert inside their chambers will remain in place for a longer time unit during the profile melting. Such a geometry of aluminum profiles enables the extension of the time of the fireproof core remaining in its original position, limiting the spread of external fire to the maximum.

The object of the utility model is shown in the embodiment in the drawing, in which Fig. 1 shows a cross-sectional view of the profile. E xample The fire-resistant aluminum profile of the warm system has an outer section 1 and an inner section 2, connected with each other by thermal breaks 3, forming a thermal chamber 4. The interconnected sections 1, 2 form three-chamber sections. The outer section 1 has an outer chamber 5, and the inner section 2 has an inner chamber 6. The thermal chamber 4 and the outer chamber 5 and the inner chamber 6 have a fireproof material inside 7. The cross-section of the outer chamber 5 and the inner chamber 6 has the shape of a rectangle with two selected opposite with corners 9 adjacent to the outer wall 10 of the outer profile 1 and the inner profile 2.
