Abstract

The invention relates to a flange profile (1) for attachment to abutting air channel elements and for receiving angle brackets for forming an assembly frame. According to the invention, the flange profiles have an essentially L-shaped cross-section. An L-limb (2) is profiled as a double-walled (3, 4) limb, which is open on one side and which is provided for overlapping the edge areas of the air channel elements, and the other limb (5) is profiled as a hollow cavity (8) for receiving a limb of an angle bracket. In the transition area of both of these limbs (2, 5), a backward folding (9a, 9b) by 180 DEGREE forms a double wall, which separates both limbs and which touches one of the wall areas (6, 7) with its backward folded lug. The aim of the invention is to achieve a greatest possible tightness in the transversal or longitudinal direction of the profile. To this end, the wall area (6 or 7) and the backward folded lug (9a or 9b) are joined to one another by means of a laser weld seam (10).

Description

Description of the invention

The invention relates to a flange profile for mounting on the protruding edges of the elements of the ventilation 2 channel and for accepting corners to form a mounting frame, and the flange profiles are made in cross-section, mainly I-shaped, and at the same time, one shelf | - a similar profile is profiled in the form of a double-walled shelf open on one side and is intended to cover the marginal areas of the ventilation channel elements, and the other shelf is profiled as a hollow chamber for receiving the corner shelf, and in the transition zone of these two shelves due to reverse folding by 180" a 70" is formed a double wall that separates both shelves and that touches one of the wall sections with its reverse fold projection.

The invention is based on the example of the applicant's patent ЮОЕ-91 14 679-001 or on the example of such flange profiles, which are described in EP-0 085 355-АТ or ОЕ-32 03 204-А1.

Known profiles, namely the type of profile that has already been described, is distinguished by the fact that it provides 12 tightness with respect to air leakage of the ventilation channel. There is also additional sealing inside the profile, for example as described in ОЕ 36 18 822 С2, ОЕ 43 03 150 A1 or СЕ 93 20 128 01. However, leakage can still occur, especially when the ventilation channels are slightly bent in such a way that air penetrates between the wall of the ventilation channel and the installed profile, and then it is reported through the clamp of the corner shelves that are used.

Creation of a method of elimination of the leak is the task of the invention, and, according to the invention, this task is solved by the fact that the section of the wall and the projection of the reverse fold are connected to each other by a laser weld.

Due to the fact that a welded seam is provided, it becomes possible to use one part of the profile as a hollow chamber and hermetically isolate the area opposite the location of the profile. In addition, the laser c 22 weld ensures that during its application there is no danger that the profile may twist during welding or be deformed in some other way.

The chamber can be made in different ways, namely, that due to reverse folding by 180" in the profile, a flat wall appears in the place where the plane of the separating joint is in the working condition. In this case, a weld seam is provided in the wall.

If the reverse folding of tin is in the plane of the separation joint and is fixed from the inside, Ge) then the laser weld, according to the invention, is located in front of the plane of the separation joint of the reverse section of the profile wall. The result of the sealing of the profile zone formed by the laser seam is the same as with the inversely formed fold. Ha")

It goes without saying that it is not necessary to apply a laser weld everywhere. As with the traditional one

From welding, a laser weld can be applied periodically, that is, gradually, and in this case - it does not depend on sealing at all, but on the torsional stiffness of the installed profile.

Such distinctive features, details and advantages of the invention are based on the following description and are also presented by means of the drawings. "

Fig. 1 and 2 - show two flange profiles, differently designed, according to the invention; From 50 Fig. 1a and 2a - show enlarged sections of the profile with a marked weld. c Flanged profile 1 is made of tin strip by cold deformation, in the transverse direction

Iz" cross-section of an I-shaped profile with a double-walled shelf, both walls C and 4 of which are placed on the end face of the ventilation channel, and with a second shelf of an I-shaped profile 5, both tin walls 6 and 7 of which form a hollow chamber 8 inside them, in which in working condition, you can insert a corner shelf, and the design of the flange profile does not matter directly for this. and Fig. 1 and 2 contain functionally identical elements with the same markings. av | In both of the above examples, the wall 6 of the shelf 5 of the I-shaped profile is shown, which in the working state forms a hollow chamber in the plane of the separating joint. Then, for example, an elastic gasket or something similar is applied to this wall. During the implementation of the variant of the invention according to Fig. 1, the reverse fold is formed by

Gee! 20 with the help of a tin wall 7, opposite in the plane of the separation joint, and touches the lower part of the chamber 8.

This protrusion of the reverse fold in Fig. 1 is marked Za. In the case of Fig. 2, this lower fold, which isolates the chamber, is formed with the help of a tin wall 6 and is located in the plane of the separating joint, this reverse fold on

Fig. 2 is marked 9.

It can be seen that the reverse folds За and 95 adjoin the opposite wall, in the first case - to 22 of wall 6, in the second case - to wall 7. The end side of the reverse projection is fixed at the same time
