Description

The present invention relates to a drainage device for draining liquid in a connection region of a post profile and a locking profile. The invention further relates to a mullion-transom profile arrangement for a facade with at least one drainage device.

The publication DE 299 10 011 U1 relates to a facade consisting of a support structure of several carriers on which facade parts such as panels, glass panes, etc. are arranged. The facade parts are held by pressure strips, which in turn can be fastened to the supports by means of fastening means. Between the carriers and the pressure bars a seal is provided. The seal cooperates with an element which covers at least one edge of the facade part.

The publication US 2,960,195 A also relates to a facade element for buildings.

The publication EP 2 397 643 A2 relates to a connecting element for closing sealing joints on facades. The facades have seals which are attached to support structures of the facade between individual facade elements. The seals, which are designed as multi-part strands, form a seal-free gap at their joints, which is enclosed by the connecting element. In particular, the connecting element closes the seal-free gap in that it spans the seal-free gap and is connected by overlapping areas at the ends of aneinsader abutting partial strands.

In facade construction in particular of building facades, it is customary, mostly made of light metal profile half shells by means of insulating webs to assemble profiles and put together these profiles truss-like structures, which can be used in the subjects mostly surface elements such as glazings or the like. Vertical running so-called post profiles run this usually continuous, while each compartment of the façade framework at the top and at the bottom is limited by one attached to the continuous post horizontally extending locking bar profile.

In order to fix the transom profiles respectively to the continuous post profiles, different connection methods are known, but with all known connection methods the problem arises that on the weather side facing outer surface of the respective profiles running rainwater can penetrate into these connection areas.

In addition to various, usually provided at the top of the respective connection areas conventional sealing elements, it is also known to seal on the outside (weather side) each of these joints between mullion and transom profiles with a suitable workable sealant such as silicone or the like.

The conventional solutions in this case have the disadvantage that in the direction of this connection area running rainwater or other liquids must be derived otherwise. In addition, there is the disadvantage that in the case of insufficient sealing of the sealing elements, for example as a result of material aging, deformations or the like, this liquid can run into the area of the surface elements, in particular into the glazing area, which leads to undesired effects.

The present invention has for its object to provide a drainage device for discharging liquid in a connection region of a post profile and a latch profile, which ensures a reliable drainage of liquid in a simple, inexpensive construction and in particular the surface elements in the formed of the post-and-bolt arrangement Keep trays largely free from liquid.

The object is achieved by a drainage device having the features of independent claim 1.

In particular, the object is achieved by a drainage device for draining liquid in a connection region of a post profile of a transom profile, wherein the drainage device in the installed state has at least one vertical section and at least one horizontal section, wherein at least one region of the drainage device facing at least one inner surface of the transom profile in the installed state a sealing element.

The advantages of the solution according to the invention are obvious. Thus, the seal member seals rainwater or the like possibly entering the joint portion in a horizontal direction and prevents the liquid from flowing thereupon in a horizontal direction along the bolt profile in the direction to run the surface element. It should be noted that an inner surface of the bar profile in the installed state designates such a surface which is directed in the direction of the insulating half-rails connecting insulating strips, while in contrast, an outer surface of the bar profile faces the weather side of the facade. The drainage device according to the invention with the sealing element ensures that even if liquid, for example in the form of rainwater penetrates into the connecting region between mullion and transom profile, this running in the gap of the abutting profiles rainwater can not spread in an undesirable manner in a horizontal direction.

Advantageous developments of the solution according to the invention are specified in the dependent claims.

For example, it is provided that the at least one region of the drainage device facing the drainage device in the installed state of the at least one inner surface of the locking profile has an outer surface. This outer surface is largely parallel to the perpendicular to the bottom and perpendicular to the mullion profile extending inner surface of the bar profile. Furthermore, the at least one region of the drainage device facing the at least one inner surface of the locking profile in the installed state has an upper surface which extends substantially parallel to the inner surface of the locking profile extending parallel to the floor and perpendicular to the post profile.

This ensures that even penetrating liquid that could spread horizontally along the inside of the bar profile in a horizontal direction, is effectively prevented by the abutting at substantially 90-degree angle outer surface and upper surface of this process.

According to a further aspect of the invention, it is provided that the at least one sealing element is designed to prevent liquid largely completely from leaving the connection region in a horizontal direction. In other words, the sealing element substantially completely seals the joint area in which running rainwater passes under the transom profile could turn off against this invading water. As a result, the tightness is improved again.

According to a further aspect of the invention, it is provided that the drainage device is arranged at least in regions essentially directly along the inner surface of the locking profile which points downwards in the installed position, parallel to the floor and perpendicular to the post profile. It should be noted that in the areas mentioned under "direct arranging" is understood a process in which just enough space for between the inner surface or the inner surfaces of the latch profile and the upper surface or the outer surface of the drainage device provided sealing element remains. By arranging along the in mounting position facing down parallel to the ground and perpendicular to the mullion profile extending inner surface of the bar profile advantageously retention of the draining liquid in the horizontal direction is ensured exactly at the place where such a propagation in the horizontal direction is particularly harmful. In other words, the entering drainage rain water or the like is effectively prevented from running into a glazing area or the like from above.

According to a further aspect of the invention it is provided that the at least one sealing element at least partially both between the outer surface of the drainage device and perpendicular to the floor and perpendicular to the mullion profile extending inner surface of the latch profile and between the upper surface of the drainage device and the parallel to the ground and is arranged perpendicular to the post profile extending inner surface of the latch profile. As a result, the tightness in the horizontal direction along all of the surfaces of the transom profile which are suitable for such undesired propagation of rainwater or the like, i. both along the plane extending in the propagation direction of the bar profile surface and in the propagation direction of the bar profile perpendicular surface, again reduced.

In accordance with a further aspect of the invention, it is provided that a region of the drainage device facing the inside of the post profile in the installed state runs at a distance from the post profile. Alternatively or In addition, a portion of the outer surface of the drainage device adjacent the joint of the mullion and transom profile may be spaced from the transom profile. In this way, a substantially vertical drainage channel is formed between the drainage device and the post profile, between the drainage device and the transom profile or both between the drainage device and the post profile and between the drainage device and the transom profile in a joint area between the post and transom profile. It should be noted that such a drainage channel for liquid is limited by the respective opposite surfaces of mullion or transom profile and the surfaces of the drainage device. A further limitation can be given for example by fastening projections or the like of the drainage device on the post profile or on the bolt profile. By means of such a drainage channel formed in the simplest way, impinging liquid such as rainwater can be safely discharged in the vertical direction; At the same time, the drainage device prevents this water from spreading in a horizontal direction along the extension direction of the transom profile.

According to a further aspect of the invention, the sealing element is arranged in a region of the outer surface and / or the upper surface of the drainage device which is at a distance from the joint of the mullion and transom profile. As a result, the essentially vertical drainage channel between the drainage device and the post profile and / or between the drainage device and the locking profile in relation to the draining liquid obstructing elements remains free of installation. In other words, the sealing member is provided in a region in which it effectively prevents the sealing against rainwater running in a horizontal direction along the transom profile, but at the same time does not hinder the drainage of this rainwater in the vertical direction in the channel between the drainage device and the respective profiled inner surface , This allows a fast and largely unhindered drainage of rainwater in the direction of the ground.

According to another aspect of the invention, the outer surface of the drainage device, the upper surface of the drainage device and / or that surface, which runs in the installed state along the inner surface of the post profile, seen from a common corner region of these surfaces from a longest direction of expansion of not more than 50 mm. In particular, when the dewatering device is formed from a suitable plastic such as EPDM or the like, a thermal improvement is achieved in addition to a desirable material savings. Furthermore, it is possible with the above dimensions to use such a drainage device in post and beam trusses with increased fire protection requirements.

According to another aspect of the invention, it is provided that the drainage device is fastened in the connection region by means of a joint connection. As a result, a particularly simple attachment directly to the installation is possible, in particular when the joint connection is made by insertion into prepared fasteners on the profile or profiles, given a simple tool-less structure.

According to a further aspect of the invention it is provided that the drainage device is formed in one piece and is preferably obtained by a vulcanization process.

By a one-piece design an excellent tightness is ensured, the drainage device can be made very inexpensive.

According to a further aspect of the invention, it is provided to provide a mullion-transom profile arrangement for a facade in at least one connection region between one of the mullion profiles with one of the transom profiles with a drainage device according to the invention described above. Preferably, a plurality of connecting regions between the post profiles and the locking profiles are provided with a drainage device according to the invention. Particularly preferably, a drainage device according to the invention is provided in all possible connection areas. This results in a safe and reliable drainage of large parts or the entire mullion-transom profile arrangement, wherein in particular when the mullion-transom profile arrangement for a building facade with surface elements is used, is ensured by the drainage device or by the drainage means that no or only a very small amount of running in a horizontal direction along the bolt profiles rainwater penetrates into areas between the surface elements and leads here to undesirable effects.

In the following, an embodiment of the dewatering device according to the invention is explained in more detail with reference to a drawing.
