Expandable foam material is applied to fill the created separation sections.

Description

The Invention relates first a method for installing a joint closure profile between two Building bodies, wherein the joint closure profile a movement section and flank sections has, connected to which flank sections of the movement section is, wherein the flank portions each of a support portion starting in the cross section extending at right angles to this.

Methods of the type in question are known from the prior art, so for example. From the disclosure of DE 9315 679 U1 , By means of such a method, a closure profile in the joint area, in particular in the region of expansion joints, for example, between two structural bodies of a facade in the longitudinal direction of the joint by means of adhesive plaster or the like attached. Here, then, the movement section is in coverage to the joint. Practically, this is a joint closure. On the other hand, it is often desirable to close the joint gap by a foam strip, in particular a foam strip impregnated for retarding recovery.

Of the Invention is based on the object, a method for installing a Specify joint closure profile with a movement section, the nevertheless access to the joint, for example. To a foam-sealing strip to use.

These Task is first and essentially in a method having the features of the claim 1 solved, with the fact that the movement section is after the Installation of the joint closure profile is separated in the longitudinal direction and the thus created separating sections of the movement section Be by inserting an expandable one Foam element are spread. As a result of the method according to the invention that originally possibly vapor diffusion closed joint closure profile in handling technology easier Way by longitudinal separation preferably formed of a soft PVC material movement section converted to a vapor diffusion open joint closure profile. So that the building joint after the longitudinal transection of the movement section nevertheless against external weather influences such as for example, driving rain or the like is protected, will be the expandable and preferably impregnated Foam element used in the joint, so that a vapor diffusion open Joint closure profile is formed. It is preferably provided that the foam element, for example, an open-cell flexible polyurethane foam with polymer impregnate is. The longitudinal separation the movement section is preferably by means of a suitable Cutting tool made, with the two sides of the movement section arranged flank sections in the course of longitudinal separation as Schnittführungsanschläge for the cutting tool can be used. The fugeneinwärts Protect foldable separating sections each in the course of the insertion of the foam element before the longitudinal narrow sides damage such as tears or the like. The separating sections effect after insertion of the foam element a permanent, tight closing Andrückung the foam element or its longitudinal narrow sides.

Further is in the inventive method provided that after installation and fixing, for example by means of a suitable adhesive plaster or the like, the closure profile for Movement absorption after curing the adhesive plaster activated by separating a closure strip becomes. Here, the movement section to the outside of covered the closure strip, wherein the preferably formed on the flank sections closure strip the Fugenverschlussprofil for mounting the necessary sta bility is there. The movement section is in the course of plastering against contamination such as plaster protected by the closure strip, so that the stretchability of the movement section is made sustainable. Both the closure strip and the movement section are in an overlapping position attached to the flank sections of the closure profile. Of the Movement section is severed after separation of the closure strip, subsequently the foam element inserted into the joint, with the separated Separating sections of the movement section in the sense of a double layer inside walls are pressed against the flank sections.

The The invention further relates to a joint closure profile for covering a fugue between two building bodies, with a movement section and flank sections to which the movement section is connected is, wherein the flank portions each of a support portion starting in the cross section extending at right angles to this and are directed away from the joint in the installed state to the outside.

Such joint closure profiles for covering a joint are known from the prior art. These closure profiles are used in particular in the facade joint area and are intended to intercept or compensate for the movements occurring between the components due to the effects of weather or mechanical stress. In addition, such profiles protect the joints from external influences such as driving rain, Dirt or the like.

For example, it is based on the disclosure of DE 9315 679 U1 directed. The movement section of this known closure profile protrudes deep into the joint in the installed state. It is formed on the flank sections in an area that is in the installed state in the joint. This known te design can prove to be disadvantageous if, for example, in the joint, in the area in which then should be the movement section, mortar residues are given. Also, the movement section is thus relatively deep in the joint, which at least prevents the gap to fill up so far.

outgoing from the above-described prior art, the invention is the Task to provide an advantageous joint closure profile.

These Task is first and essentially in a joint closure profile with the features of claim 2, it being pointed out that the movement section is thus at the flank sections Tied is that he is over the support sections extends in the direction away from the joint. according to Such an embodiment is an advantageous joint closure profile, in terms of assembly, for example. About the preferred perforated Pad sections, the joint closure profile in a known manner by means of adhesive plaster or the like at the joint edge region of the surfaces of building body be attached. Here, the movement section takes in an advantageous Way one outside the joint cavity arranged position, so that in a simple way the stretch and Upset zone not as usual in the interior of the joint, but outside the joint cavity is settled. This allows overall a favorable installation of the joint closure profile, there possibly joint contamination such as inclusions or the like assembly the joint closure profile according to the invention not unnecessary hinder. Consequently, the installation cost of such a joint closure profile simplified. In addition, there are damages the movement section, possibly by the joint inclusions push in the movement section can arise, counteracted in a simple manner. Preferably, the movement section at the flank sections in their fugitives turned away, over Tying the support sections extending areas. Also is It is advantageous that the respective connection areas of the movement section are aligned facing each other and each of the outwardly projecting spring free ends of the flank sections. The in the installed state joint-facing flank sections are in their extension length (extension in the thickness direction of the plaster layer) in each case preferably dimensioned that the extension length essentially a thickness gauge for the plaster layer pretending, wherein the upstanding flank sections or their free Ends also each act as plaster edges. Because the movement section positioned between the flank sections is an optimal Space utilization given. As a result, the joint closure profile has also an advantageously small depth cross section. The connection of the movement section does not have to be necessary in the joint facing away Be made areas of flank sections. The connection can also be in a below the level of the support sections (or in the plane of the support portions) located portion of the flank sections made be. In particular, if the movement section, moreover, optionally including an acute cross-sectional angle to the respective flank section or as soon reversal, itself after the education fugenauswärts extends.

The objects the further claims are but explained below with reference to the subject-matter of claim 2 even in their independent Be meaningful.

Thus, it proves to be advantageous that the movement section consists of a plastic material which is soft in comparison with the flank sections. It is thus preferably provided that the movement section consists of a soft PVC material and the flank sections consist of a hard PVC material. With regard to the production, for example, a conventional extrusion process is used. Since the movement section is preferably made of a diffusion-proof soft PVC material, a vapor diffusion closed joint closure profile is created. For example, in the course of assembly, the joint closure profile in longitudinal extension has a desired stability, can also be provided that the movement section is covered to the outside by a detachable closure strip, which also serves as a cover for the movement section. This is also favorable during the plastering process, since the softly formed movement section is protected from contamination or even damage by the closure strip. The connection of the closure strip to the joint closure profile is preferably carried out in the extrusion process, wherein the closure strip more preferably consists of a hard PVC material. The non-separated closure strip forms, together with the movement section in cross-section, a triangular surface, wherein the movement section extends inwardly only up to the plane defined by the support sections arranged at right angles to the edge sections. This means that the movement section does not have the up contact surfaces of the support sections protrudes. In the installed state of the closure profile, the closure strip forms the outward-facing ground, as it were the hypotenuse, the triangular surface, wherein the closure strip is formed respectively on the outer edges of the free, outwardly facing ends of the flank sections and covers the attachment areas of the movement section. Abreißgünstig proves the measure that the closure strip may have a cross-sectional reduction in the form of a film strip at its longitudinal extension areas. The orientation of the movement section starting from the clamped base surface is such that the movement section or its conformally formed leg in the installed state preferably faces an obtuse angle, the approximately V-shaped legs being joint-connected to one another via a leg turn forming the triangular tip , The outer wall of the sweeping area is preferably located on a plane corresponding to that of the bearing surfaces of the bearing sections. This means that in the fixed state of the closure profile of the movement section is indeed aligned facing the fugue, but nevertheless the movement section runs stretched over its turn before the joint opening. After the drying process of the plaster, the closure strip can then be detached by detachment from the closure profile, so that the closure profile is activated for movement absorption.

Around is to increase the range of use of the joint closure profile is provided that this in a simple manner from an originally possibly vapor diffusion closed is convertible into a vapor diffusion open state.

This will be suggested that the movement section in the fixed state the closure profile by longitudinal separation to the outside facing portions of the flank sections is umlegbar. It means that by means of a corresponding cutting tool in front of the joint placed movement section or its legs by preferred central longitudinal separation the turn divided equally can be. It can also be provided that the inner wall of the turn in the longitudinal direction has a notch, which practically gives the user a predefined cutting path indicates the separation of the movement section. The soft, separated leg sections are then inwardly in each case pivoted. Next, the invention provides that in the so created joint clearance a foam element forming Joint sealing tape can be used. This joint sealing tape is preferred precompressed, delayed provision waterproof and also due to the foam material vapor diffusion capable. When Foam material can, for example, an open-cell flexible polyurethane foam with polymer impregnate be used. In the course of insertion of the foam element become the separated leg sections of the movement section in the sense of a double layer in each case in opposite directions against the inner walls pressed the flank sections. Due to the insertion of the foam element are the Separating sections aligned facing the groove, parallel, which facilitates the insertion of the foam element and this if necessary against marginal damage protects. The thus applied to the flank sections separating sections form practically already outside the groove an introductory channel for the Foam element. In addition, the separating sections are in inserted Foam element tightly closing on the narrow sides of the foam element. Another advantage results from the measure, that the movement section in the non-separated state to not more than the measure of Extension of the flank sections to the outside over the support sections after protrudes inside. The non-separated separation sections of the movement section extend in a cross section in the unseparated state within a cross-sectional area defined between the flank sections, though the length one for considered separating section may well be larger than the measure of outward over the support sections extending flank sections. This is achieved by an orientation of the movement section or the Separating sections at an acute angle to the flank sections.

The Invention will be described with reference to drawings, which only here Represent embodiment explained in more detail: It shows:

6 the following description according to 5 concerning the activation of the joint closure profile by separating a closure profile;

7 a perspective view according to 6 and

8th a sectional view according to 6 , but with vapor-permeable foam element inserted into the split closure profile.

Shown and described is a joint closure profile 1 to cover an expansion joint 2 between two buildings or parts of buildings 3 and 4 For example, these may be slabs of a prefabricated building or the like.

The joint closure profile 1 consists essentially of two conformal L-sections, wherein in the installed state, the equally aligned and facing away L-legs each support sections 5 form. The right angles from the L-legs or from the support sections 5 extending L-webs each form flank sections 6 out. Connected are the flank sections 6 over one on the inner walls 7 the flank sections 6 rooted movement section 8th , The one with the flank sections 6 an approximately Z-shaped cross-section forming movement section 8th is on the inner walls 7 the flank sections 6 integrally extruded. It is preferably provided that the support sections 5 and the flank sections 6 made of a hard PVC material, wherein the movement section 8th is formed of a soft PVC material. The connection of the movement section 8th on the inner walls 7 is chosen so that the thighs 9 of the movement section 8th below the outwardly facing free front ends of the flank sections 6 lead. That means the movement section 8th articulated at areas 6 ' the free ends of the flank sections 6 is connected.

So that the closure profile 1 has a certain stability for mounting, it is provided that on the outer edges of the front ends of the flank sections 6 one of the longitudinal extension of the closure profile 1 following a closure strip 10 filmbandartig is extruded. Preferably, the closure strip exists 10 made of a hard PVC material.

As in more detail in 4 to recognize the determination of the closure profile 1 over the surface of the buildings 3 and 4 resting support sections 5 , For example, in a first assembly step by means of a suitable adhesive plaster 11 or similar. The measure has a supporting effect that for this - temporary - attachment of the closure profile 1 in each case the support sections 5 of preferably circular openings 12 are interspersed. In addition, it is also provided that on the bearing surfaces of the support sections 5 for better plaster connection Reinforcement grid 13 are arranged, in turn, in the installed state flat on the building structures 3 and 4 are positioned. The temporary assembly is facilitated by the closure strip 10 because through this the closure profile 1 has an inherent stability, which turns out to be advantageous in the course of assembly, as this can be formed over the entire length of a uniform output joint.

The assembly of the closure profile 1 is due to the inventive arrangement of the movement section 8th simplified. As can be seen, that is between the flank sections 6 arranged movement section 8th outside the fugue 2 positioned. A time-consuming and cumbersome insertion of the movement section 8th into the fugue 2 can be omitted here. In addition, the foot must ge 2 in advance, must not be freed from contamination or joint inclusions. It can also be provided that the connection areas 6 ' of the movement section 8th with greater distance to the closure strip 10 inside wall at the flank sections 6 , So far facing, are connected, so that the Z-turn K of the movement section respectively over the support surface of the support sections 5 protrudes, so depending on the joint width in the course of assembly of the movement section 8th with its leg flanks a longitudinally defined assignment of the closure profile 1 into the fugue 2 can be enabled.

After appropriate drying of the adhesive mortar, the building body 3 and 4 by means of a suitable plaster 14 be plastered flat (see in particular the illustration in 5 ). The perpendicular of the support sections 5 protruding flank sections 6 not only form a plaster edge for the plaster 14 off, but give along with the thickness direction of the closure strip 10 a Verputzmaß M for the plaster 14 at.

Is sufficient curing of the plaster layer 14 achieved, the closure profile 1 by tearing off the closure strip 10 be activated, so that due to the soft trained movement section 8th a vapor diffusion-closed expansion joint can be produced. The at the flank sections 6 molded closure strips 10 can each have a non-illustrated cross-sectional reduction for better separability at its attachment areas.

According to the invention it is provided that this vapor diffusion closed closure profile 1 in a vapor diffusion open closure profile 1 is convertible. For this purpose, it is proposed that the movement section 8th in the region of its Z-turn K, cut it by longitudinal separation along the axis x by means of a corresponding cutting tool bar is. In view of this, it can be provided that the movement section 8th arranged in longitudinal extent inside wall of his turn a cutting line forming a notch, via which the cutting edge of the cutting tool can be performed improved. In addition, a uniform division of the movement section 8th reachable. Following this, in the opening area thus produced the joint 2 a precompressed, preferably impregnated, diffusion-open foam element 15 in the form of a joint sealing strip in the closure profile 1 be used. In the course of insertion of the foam element 15 become the separated and separated separation sections 9 of the movement section 8th folded inwards, until these with their outer walls in each case flat against the inner walls of the flank sections 6 issue. Due to the smooth surface of the separating sections 9 protect these during insertion, the narrow sides of the foam element 15 from damage. The foam element 15 After insertion, it is clamped in the closure profile 1 a, wherein the separating sections 9 each flush and tight sealing on the narrow sides of the foam element 15 issue.

Thus, the range of applications of the joint closure profile according to the invention 1 increases, since this is easily converted from an originally possibly vapor diffusion closed in a vapor diffusion open state. By impregnation of the vapor diffusion-open foam element 15 is a rain-proof seal of the joint 2 guaranteed.
