Description

The present invention relates to a device for holding the edge zone of a film on a wall section, as is usually the case in flat roofs or on terraces is used. Usually, the sealing in these environments is initial the on-site subsurface is sealed with foils or sheet-like material, whereby in the area of wall transitions, the material itself is pulled up around the edge or a so-called drag strip is used. According to the flat roof directive should have a seal with regard to rising components of at least 150 mm be provided from the water-bearing level.

The current common practice is to first seal the sealing material on the rising one To glue component, after which a so-called wall connection rail on the edge area is applied so that a permanent protection against tearing and slipping mechanically provided. The top edge of such strips is usually by means of Sealant such as Sealed silicone, creating a so-called maintenance joint.

After having an enormous level of manual dexterity and a lot of work various attempts have been made to improve this ready to provide. A major problem factor is the fact that a drapery can practically no longer be eliminated during the initial bonding, whereby the in Question coming contact adhesives are solvent-based, so that these days ecological and physiological aspects are no longer justifiable.

Therefore, devices were exemplified in DE-A-2244386 and in DE-A-6942103 proposed to hold the edge zone of a film on a wall section, which is the initial Avoid sticking. The devices described here have a a profile formed substantially U-shaped cavity for receiving the Edge zone, which has means for moving the edge zone out of the Inhibit cavity.

It has now been shown that these generic devices have a certain Represent improvement, but they still require regardless of nature the adjacent wall a manual seal using sealant, which generally is to be regarded as a maintenance joint and therefore needs constant control.

It is therefore an object of the present invention to provide such a device for holding the Edge zone of a film on a wall section with a formed in a profile essential U-shaped cavity for receiving the edge zone, which has means which inhibit movement of the edge zone out of the cavity in such a Way to further develop that they are universal for almost any wall section can be used. Another object of the present invention is in using such a device to save material, in particular Waste remnants should be easier to use.

According to the invention, this object is achieved in that the profile is reversible, with at least two different, essentially mutually opposing contact surfaces, which are optional, in particular dependent of the nature of the wall section are brought into contact with it can. In other words, the wall connection device comprises at least one reversible profile two different contact surfaces, depending on the properties of the wall section can be adapted. Furthermore, the reversibility of the profile saves material achieved in that cut-off residues are better processed by the fitter can be.

A windproof is advantageously between the edge zone of the film and the device Intervention formed. This intervention can e.g. by positive locking between the profile and the border zone.

In a preferred embodiment, at least one of the contact surfaces is with a Device provided to receive a prefabricated sealing element. By a Means for receiving a prefabricated sealing element can with appropriate Condition of the wall section of a seal by means of a so-called sealing lip can be achieved so that the previous maintenance joint can be dispensed with. Should the

Condition of the wall section no seal by means of a sealing lip or similar Allow any kind of prefabricated seal, the profile can be easily turned around classic sealing using sealing material, e.g. Silicone to perform.

The profile is advantageously in the region of the cavity and / or above the edge zone with the wall section by fasteners, e.g. Fixable screws. By the fastening means in the area of the cavity and in particular above the edge zone provides, the risk of damage to the sealing sheet material or the Foil can be reduced, especially in this area only low tensions of the material are present and the material itself can be thickened.

In a further preferred embodiment, this is a movement of the edge zone inhibiting means such that the movement at different positions of the Border zone can be inhibited. In other words, this embodiment allows tolerance compensation to be provided by moving the edge zone to to the desired tension of the film in the profile and then in this position is held. Furthermore, with this configuration it is possible to start with the edge zone only slightly to get a pre-fixation, then the edge zone can be inserted in the final position to the desired one To achieve tension and / or the desired hold.

In a preferred embodiment, a web is formed in the cavity of the profile. By providing a ridge in the cavity, the contact surface can the edge zone can be increased, optionally also the fixation by an intervention the edge zone with the web engaging with respect to the legs of the U-shaped Can complement and / or replace the cavity itself.

In a further preferred embodiment, the edge zone is formed in two layers and / or has a cavity. The two-layer design enables an improved Adaptation to the cavity itself, the space between the two layers can also serve to accommodate a web, insofar as this is available. The Indian Edge zone self-formed cavity enables the deformation properties of the

Edge zone affect what happens when inserting the edge zone into the cavity of the profile can contribute to the fact that the insertion is easier, due to the elasticity a secure hold is guaranteed in the edge zone. The one trained in the peripheral zone Cavity could also be filled in later, so that after insertion a Deformation of the edge zone itself can only take place to a reduced extent.

The profile and / or the edge zone advantageously includes sawtooth-like projections. Sawtooth-like projections enable an intervention in a particularly simple manner or to generate a catch between the edge zone and the profile.

As an alternative or in addition, a body can also be mounted in the cavity movement of the edge zone out of the cavity engages it. exemplary a round profile bar should be mentioned here, e.g. arranged captively in the profile is, for example, the open legs of the U-shape in the opening area to each other approach.

It is further preferred that the profile has a facing support device, in particular provided with hanging means and / or locking means. By providing a veneer support device becomes the application of the invention Device increased even further, since both the wall sealing and the facing the same can be represented simply and inexpensively.

Advantageously, the veneer itself forms part of the invention Device, which is designed to be attached to the profile and / or locked is.

The facing device is advantageously also with a locking mechanism provided, which in particular in the longitudinal direction of the profile slidably a portion of the Reach behind and / or intervene. The additional provision of a locking mechanism also allows large-area veneers to be securely fastened, with the Proposed sliding latch a particularly easy to use and inexpensive manufacturable locking enables.

A lamination can preferably be applied to the veneer device, e.g. can be glued or screwed. This alternative is particularly in the Area of terraces advantageous because the terrace covering itself to hide the seal of the rising component can be used.

Finally, it is preferred that the facing device forms a channel. Such a gutter can be used as a drainage channel in the flat roof or terrace area, for example so that the additional provision of such a channel becomes superfluous.

The device comprises a profile 20, which can be made of aluminum, for example, and which according to the invention has two essentially opposing contact surfaces 28, 29. As shown, the profile can optionally be with the contact surface 29 (as shown in Fig. 1) or the contact surface 28 (as shown in FIG. 2) with a wall section 1 in Plant are brought, the selection depending on the nature of the Wall section is done.

If the wall section 1 has a smooth and advantageously dust-free surface, the profile 20 with the contact surface 29 abutting the wall section 1 are attached, with a prefabricated sealing element 30 partially between the profile 20 and the wall section 1 is arranged. By attaching the profile 20 to the prefabricated seal 30 is applied to the wall section 1, so that it is formed Sealing lips 36 are pressed against the wall section 1. Around the seal 30 to secure against slipping, the profile 20 has a receptacle 24 in which a Projection 34 of the seal 30 is received. In addition to the sealing lips on the wall 36, the prefabricated seal 30 comprises a projection 32 which covers it on the profile side, to prevent running behind.

In the lower area, the profile 20 has an essentially U-shaped cavity 22, in which projections 23 extend slightly upwards. This Cavity 22 is designed to interact with a so-called keder profile 12, which, with appropriate dimensioning and configuration, form-fitting in the Cavity 22 can be performed. The keder profile 12 can be made in one piece with the film 10 be formed, or connected to it as shown, e.g. by vulcanization, Gluing or similar techniques. As shown, the piping profile 12 via slightly downward projections 13, which the projections 23 of the cavity 22nd can reach behind. Those skilled in the art will recognize that these are reciprocal, sawtooth-like trained projections 13, 23 an insertion to different degrees is possible while moving out is prevented at all times. In this It should be noted that, unlike in the prior art, a surface contact is present, so that in addition to the moisture seal, a wind seal is also achieved can be.

However, if the nature of the wall section 1 does not allow it, a To achieve sealing by means of a prefabricated sealing element, it is sufficient to close the profile turn and provide in the arrangement of FIG. 2 on the wall section. After Attachment of the profile 20 can this with respect to the wall section 1 by a classic Maintenance joints are sealed.
