CZ302442B6 - Building section with reinforcing grid - Google Patents

Abstract

The present invention relates to a building section with reinforcing grid (4) being fixed in at least one arm of the section. In the corresponding arm end section, there is performed a cavity terminated by a resilient lock (3). Edge portion of the reinforcing grid (4) is inserted along with a fixing wire inside said cavity where it is fixed by the resilient lock (3) and bent over the fixing wire.

Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to a building profile with a reinforcing grid, which is intended primarily for thermal insulation systems of external walls of buildings. It is a building profile whose at least one arm is connected to a fixing grid strip.

BACKGROUND OF THE INVENTION

At present, building profiles for thermal insulation systems, in particular window profiles, are connected with a plastic reinforcement grid, resp. reinforcing grid based on glass fabric (lining). In the prior art solutions, the grille is fixed to the arm of the base body of the profile, for example by ultrasonic welding by means of an additional welding string.

In another solution - according to the application EP 128 1822, a strip of reinforcing grid is inserted between two co-extruded parts of the building profile. These parts are then pressed together while still in the soft plastic state to join together to form a finished building profile strip with a fixed reinforcement grid.

In the design according to utility model CZ 17950, the fixation grid is fixed between two clamped sub-parts of the respective arm of the profile base body, in the clamped state by fixed welding.

While the above-mentioned solutions ensure a firm connection of the reinforcement grid to the profile, they are demanding from the technological, energy and hence economical point of view.

SUMMARY OF THE INVENTION

To a large extent, the construction profile with a reinforcing grid fixed in at least one of the arms according to the invention contributes to overcoming the drawbacks of the prior art. SUMMARY OF THE INVENTION The invention is based on the fact that in the end portion of the respective leg of the profile, a cavity terminated by a resilient fiber is formed in which the edge portion of the reinforcing grid is inserted and locked together with the fixing wire around which it is folded.

Advantageously, the edge of the reinforcement grid folded around the fixing wire upwards in the region above the end of the arm of the profile may duplicate the reinforcement grid over its entire length or at least in part thereof.

The spacing of the ends of the arms of the flexible lock is preferably equal to 1.8 to 2.1 times the thickness of the reinforcement grid.

The main benefit of the invention is that it provides a sufficiently effective fixation of the reinforcement grid in the profile arm without major technological and energy requirements.

DETAILED DESCRIPTION OF THE INVENTION

The building profile in the exemplary embodiment (see Fig. 1) is provided with a reinforcing grid 4 based on a 5 glass fabric (gauze) which is fixed in its arm L

A cavity 2 is formed in the end portion 1 'of the arm 1, terminated by a resilient lock 3, in which an edge portion of the reinforcing grid 4 is inserted and fixed by the lock 3 together with a fixing wire 5 of circular cross section around which it is folded.

i o

The edge of the reinforcement grid 4, folded upward, forms a doubling of the reinforcement grid 4 over a portion of its length at a distance of 25 mm above the end of the arm 1 in the region above the end of the arm 1.

The spacing of the ends of the arms 3a of the spring lock 3 is equal to 1.9 times the thickness of the reinforcement grid 4.

The width of the cavity 2 given by the distance of its side walls 2b and the height of the cavity 2 given by the distance of the ends of the arms 3a of the flexible lock 3 from the base 2a of the cavity 2 are equal to the sum of the fixing wire diameter plus 2.1 times the reinforcement grid 4.

Claims (3)

25 PATENT CLAIMS A building profile with a reinforcing grid which is fixed in at least one of the legs of the profile, characterized in that a cavity is formed in the end portion (1 ') of the respective leg (1) 30 (2) terminated by a flexible lock (3) in which the edge portion of the reinforcement grid (4) is inserted and fixed (3) together with the fixing wire (5) around which it is folded.
