Description

f Building profile with fire protection for external thermal insulation systems

Technical field

The technical solution concerns a building profile with fire protection for external thermal insulation systems. This fire-retardant treatment significantly increases the overall fire resistance of a given ETICS (Extemal Thermal Insulation Composite Systems).

BACKGROUND OF THE INVENTION

At present, a number of different constructional profiles designed to be built into the plaster are known for the purpose of reinforcement and easier plaster placement in the area of various building edges - in corners, at windows, doors (lining), etc. Particular design solutions of profiles are quite specific depending on the purpose of using a particular profile.

Building profiles are often used to reinforce plaster in the installation of thermal insulation (external thermal insulation composite) systems. In particular, corner profiles intended for the application of thermal insulation systems for the plaster reinforcement in the corner parts of the building are known. Currently used standard corner profiles (for example, a corner profile with a drip, which is installed on the outside of the window sill) are usually equipped with two strips of anchoring glass fabric attached to the individual legs of the profile from the outside - see e.g. The solution according to German patent application no. 19718450, wherein the corner profile has a glass fabric web attached to each of the arms by ultrasonic welding. Between the two belts there is an interruption which forms the plastic drip nose of the profile. The problem then is that this solution does not ensure the integrity of the thin layer formed by the sealant on the polystyrene insulation. The flame load then breaks the sealant and the subsequent flame penetration to the layer of insulation boards.

A certain effort to solve this problem is to construct a corner profile according to other German patent applications no. 195 & 527 and 19527028, respectively. PCT Application No. WO9704197, wherein the strip is joined to the corner profile as a whole and encircles the plastic drip nose of the profile. Obvious drawbacks of this solution are manufacturing and application complications and unstable fixing of glass fabric, which, after the plastic burn-out, does not guarantee the cohesion of the putty layer - the leveling compound.

The essence of the technical solution

The construction profile with reduced flammability for external thermal insulation systems according to the present invention contributes to the elimination of the above-mentioned deficiencies. It is a building profile formed as a building profile consisting of at least one rigid plastic arm and at least one strip attached thereto by an anchor fabric. The essence of the new technical solution is that at least one of the bands of the anchor fabric is folded or angled and fixed to at least one arm

Thus, two free ends of the folded base anchor web or one of the ends of the folded additional anchor web and the free end of the base anchor web are directed parallel to or above the edge of the respective arm.

In the simplest configuration of the building profile, the folded base anchoring web in the region of the fold line is fixed to the profile arm so that its two parts extend with their free ends parallel to the edge of the profile arm.

An angled strip of the base anchoring fabric can also be fixed to the arm of the building profile. In this case, the two parts thereof, with their free ends, extend over the edges of the profile arm in an angular configuration.

In the angular (corner) building profile, the angled strip of the additional anchoring fabric may be attached to the inside of the two-arm angled building profile to at least one of its arms, each of its free ends facing above the edge of one of the arms parallel to the end of the base anchoring strip attached to its outside.

The base anchoring fabric, respectively. the additional anchoring fabric is preferably a glass fiber mesh fabric, which may also be provided with a non-flammable surface layer based on inorganic impregnation.

Equipping the building profile with a folded or folded solid strip of the base, respectively. additional anchoring fabric reinforces the sealant layer under the profile and thus ensures the integrity of the thin sealant layer even at the outer corner - e.g. corner of the window rail. In the case of combustion, in contrast to the known profiles, the sealant is not damaged and the flame penetrates to the layer of insulation boards.

Examples of technical solution

Example 1

The profile for joining the lining and the lintel to the window frame (see Fig. 1) is made of unplasticized polyvinyl chloride and has a folded base anchor web 4 in the region of the fold line fixed to the arm 2. The two parts of this base anchor web 4 then point with their free ends above the edge of the arm 2 of the profile.

The base anchoring fabric 4 is a glass fiber mesh fabric, which may be provided with a non-flammable surface layer based on inorganic impregnation.

In FIG. 2 is a schematic representation of the placement of the insulation board 6 of the external thermal insulation composite system (ETICS) using the building profile of FIG. 1, wherein by wrapping the insulation board 6 at one end of the anchoring fabric 4, the integrity of the thin layer of sealant under the profile is ensured and prevents flame penetration to the insulation board layer in the event of a fire.

Example 2

Another variant of the building profile for joining the lining and the lintel to the window frame (see Fig. 1a) has an angled strip of the base anchoring fabric 4 fixed to the arm 2 so that its two parts point in an angular arrangement with their free ends above the edges of the profile arm 2. .

The base anchoring fabric 4 is a glass fiber mesh fabric per line, which may be provided with a non-flammable surface layer based on inorganic impregnation.

The placement of the insulation board 6 of the external thermal insulation composite system (ETICS) is practically identical to that of the building profile according to Example 1 (see Fig. 2). By wrapping the insulation board 6 with one of the ends of the anchoring fabric 4, the integrity of the thin layer of sealant under the profile is again ensured and flame penetration to the insulation board layer in case of fire is prevented.

Example 3

The two-armed angular building profile with a drip to incorporate the outer corner of the lintel (see Figs. 3 and 4) has anchoring strips of base anchoring fabric 4 on both sides of both arms. On the inside of the building profile X is then to one of its arms 2 and 2. 3, an angled folded strip of additional anchoring fabric 5, each of its free ends pointing above the edge of one of the arms 2 and 3 parallel to the base anchoring fabric 4, respectively. 4 'to the respective arm attached to its outside.

The additional anchoring fabric 5 is a glass fiber mesh fabric per line, which may be provided with a non-flammable surface layer based on inorganic impregnation.

In this case, the insulation board 6 of the external thermal insulation composite system (ETICS) is embedded in the integral strip of the additional anchoring fabric 5, which again ensures the integrity of the thin sealant layer under the profile and prevents flame penetration to the insulation board layer in event of fire.
