Abstract

The system comprises several adapter profiles (21) and seals (23), and the post-and-beam profiles (13) which are detachably connected to the adapter profiles on the building (2). The adapter side connection elements (22) are attached to the standardized seals, and the adapter profiles are arranged such that its side faces the side of building, according to the outer shape of the existing post-and-beam system. The adapter profiles are made of aluminum and the post-and-beam profiles are screwed to the adapter profiles.

Description

The invention relates to a system of elements with which existing building facades in post-and-beam construction are adapted to today's energy-saving requirements.

State of the art

It has long been known to create facades with glass or sheet metal panel fillings by attaching or restraining the panels in post-and-beam systems. So z. For example, the scriptures DE 29915574 U1 . DE 202007015301 U1 and WO 2005 064096 A2 to call. All documents consistently show systems for attaching facades to buildings.

Existing building facades made of aluminum profiles in mullion-transom construction with glass and metal panel fillings from 1970 to 2000 correspond to the older they are, sometimes seriously no longer comply with today's energy saving regulations and contribute significantly, due to the excessive heating demand, for raw material destruction and energy waste. Usually old existing facades of the type described in the course of extensive renovation measures on the entire building by new, contemporary and technically located on the state of the art facades of the same type are replaced.

Although these overall remedial measures are necessary, but expensive and time-consuming and usually require that the building remains unused during the construction - but at least during the dismantling of the mullion and transom profiles. These vacancies cost additional money as spare rooms need to be rented.

The old facades are dismantled in small parts in the renovation, separated into raw materials and the aluminum of the profiles in the raw material cycle by melting down. However, this recycling process again costs resources and money due to the high energy requirement, and also produces complex by-products and toxins.

After dismantling the old façade, a new façade is erected on the building, the components of which are expensive in their manufacture as well as in their delivery, with the posts and latches sticking out.

Presentation of the invention

The object of the invention is to provide a system of elements, with the existing building facades in post-beam construction can be adapted to increased energy savings requirements without the facade must be completely removed.

According to the invention the object is achieved by the features of the system of elements for the renovation of building facades post-beam construction according to claim 1. The dependent subclaims show embodiments of the system of elements for the renovation of building facades in post-and-beam construction.

It can be assumed that it makes sense to continue using the valuable parts of existing post / tie systems. This is particularly the case for the mullion and transom profiles of the case, which in many cases still meet today's requirements and in particular were inferior in the course of the existing life of the facade the least external influences. In addition, the removal of these profiles from the building is associated with the greatest cost, among other things, because the removal in many cases requires the extract of the subsequent premises.

Another advantage is therefore that the renovation can be done while the building to be rehabilitated the use is maintained. Since only the Fassadenfüllelemente removed and all sealing elements are removed, can be proceeded step by step in the cultivation of the higher quality insulated Fassadenfüllelemente and new sealing elements, so that the external work can be limited to a smaller area, which moves successively around the building.

In order to adapt the existing profiles to the existing requirements of the insulating properties, it is necessary to attach adapters to these profiles, which are designed so that provided post and bolt seals remain universally usable and further sealing elements produce the better insulation. The current systems have, in addition to old screw receptacles for attachment recordings for sealing strips, which are arranged on the side facing away from the building of the hollow sections.

On the existing mullion and transom profiles, which were not removed after removal of the facade fillings in the renovation of the building, several elements are placed. First, a sealing tape is inserted, which is adapted to the sealing tape recording of the old profile that it terminates with its outer side at the upper edge of the sealing sheet recording. On the filled with the sealing tape sealing tape adapters adapter profiles are then applied in the manner described above and dependent on the shape of the Altprofils, with a screw especially offering. An adaptation to the existing mostly aluminum hollow sections - ie the design of the adapter profiles in aluminum - is particularly preferred.

The adapter profiles in turn have fasteners that allow easy insertion of other system parts, such. B. to the outsides of the hollow sections inclined noses. On the adapter profiles then a seal is placed on the side facing the building has recordings in which adapter connecting elements engage such that a release of the seal is only possible with the use of force again. The seal completely covers the side of the hollow profile facing away from the building and therefore also comprises the old screw receptacle. In addition, the seal on the side facing away from the building seal connection elements on which an insulating profile can be placed. The dimension of the insulating profile is chosen so that it fills the space between the new Fassadenfüllelementen and corresponds in depth to about the thickness of the new Fassadenfüllelemente.

Although it is conceivable to form adapter profiles and gaskets in one piece, however, speaks against that in the wake of z. B. in case of fatigue of the seals, the seals are difficult to replace, since they must be solved by the profiles consuming. A releasable positive connection has the advantage that a quick replacement of the seals is made possible without having to release the necessary element - the adapter profile - of the bar or post profile.

On the seal lips are provided which cover the adapter profile and possibly also a part of the hollow profile. From the outside, a pressure profile is attached to the building facing outer seal and fastened with a new screw. In this case, the outer seal is preferably designed so that it covers the space with befindlichem Dämmprofil. On the pressure profile, a cover strip is placed.

In order to meet higher loads with new Fassadenfüllelemente, reinforcing elements can be inserted, transfer the loads of Fassadenfüllelemente on the old transom and post profiles. Thus, despite the designed for lower loads design, especially by a smaller number of attachment points, instead of poorly insulated glass panes multi-insulated facade glass panels apply. For this purpose, the load of Fassadenfüllelemente is transferred by means of attached to the transom glass slides on the transom profiles. The now increased on the latch profile ballast is in turn transmitted to the posts via the reinforcing elements.

In the event that the old screw receptacles when removing the screws during the degradation process of the old façade are badly affected or already damaged during the original erection have been permanently, it is also possible to design the adapter profile such that an integrally formed adapter profile, which is placed on the existing post or bar to the old screw holder around summarizes and at the same time in turn has a new screw receptacle, wherein the position of the new screw receptacle on the adapter corresponds to the position of the old screw receptacle on the post or bar. The adapter profile is doing in a suitable manner, z. B. connected by screws or rivets with the old profiles at previously provided for screwing bodies.

During refurbishment, the old building façade is removed, whereby the mullion and transom of this façade remain. On the basis of the existing posts and bars an adapter profile is selected, which is attached to the old hollow sections. Beforehand, a sealing tape can be inserted as a function of the connection areas present on the old hollow profiles. On the side facing away from the building of the adapter profile adapter connection elements are provided which provide independent of the appearance of the substructure a connection option for seals and other elements that can accommodate a standard seal for bars or profiles. As a result, then sealing elements, Fassadenfüllelemente and if necessary, reinforcing elements are pre-set and fixed, as is done in the construction of a conventional facade from scratch.

1 shows a section through a post of a widely used post-bolt system according to the prior art. This system is intended to be exemplary only, other systems also show a similar structure with the same problems of poor insulation of the building that no longer meets today's requirements. Almost all systems have the common feature that the support profiles have a receptacle for a screw, are attached via the facade filler elements using pressure profiles on posts and bars. The representation of the post profile can also be used as an example for the transom profiles.

The system shown has a post profile 1 which is on the building 2 is attached. The post profile 1 is designed essentially as a rectangular hollow profile, being attached to the building 2 opposite side usually two over the length of the profile continuous inner sealant receptacles 3 and a bunch of old screw shots 4 are provided. In the inner sealant receptacles 3 are inner sealing bands 5 intended. On the building 2 On the opposite side, the system has a flat designed old pressure profile 6 , which also has outer seals 7 features. Also here are outer sealing bands 8th intended. Through the old pressure profile 6 be old screws 9 in the post profile 1 arranged old screw shots 4 screwed in between the sealing bands 5 and 8th arranged old Fassadenfüllelemente 10 to secure. Finally, an old cover strip 11 on the old pressure profile 6 Applied to lift the visual impression of the facade.

The old facade filling elements 10 Often, they no longer have the quality required to meet energy-saving requirements. In addition, the figure shows a cavity 12 through which the old screws 9 be carried out for attachment. In addition, usually have the sealing tapes 5 and 8th only a poorer insulation quality, so that the overall facade is poorly insulated against heat and cold.

In known systems according to the prior art is added that the post profiles 1 opposite the transom profiles 13 sometimes also have a smaller depth, so that with internal sealant absorption 3 and old screw holder 4 provided side of the post profile 1 Closer to the building than the same side of a bolt. Also arise from an energetic point of view disadvantages in the insulation.

The inventive system of elements for the renovation of building facades in post and beam construction is based on the 2 shown for an existing latch in an exploded view. On the bar profile 13 after removal of the facade filling elements during the renovation of the building 2 was not removed, several elements are set up. First, a new sealing tape 20 let in, which in such a way to the sealing tape recording 3 The old profile is adapted to fit with its outside on the top edge of the sealing sheet receptacle 3 concludes. On the one with the new sealing tape 20 filled sealing tape recordings 3 then become adapter profiles 21 , which are in a particularly preferred form of aluminum, applied, with a screw particularly offers. The adapter profiles 21 have fasteners 22 on, which allow easy insertion of other system parts, such. B. to the outsides of the bar profile 13 inclined noses.

On the adapter profiles 21 then becomes a dead seal 23 put on the building 2 facing side has recordings, in which the adapter connection elements 22 intervene such that a release of the bolt seal 23 only with the use of force is possible again. The bolt seal 23 covers the building 2 opposite side of the bar profile 13 completely and therefore includes the old screw holder 4 , In addition, the dead seal on the building 2 opposite side bolt sealing connection elements 24 on top of which an insulation profile 25 can be put on. The dimension of the insulation profile 25 is chosen so that it is the room 29 between the new facade elements 26 fills and in depth about the thickness of the new Fassadenfüllelemente 26 equivalent.

At the bolt seal 23 are tie ribs 34 provided the adapter profile 21 and a part of the bar profile 13 cover.

From the outside, a new pressure profile 28 with outer seal facing the building 27 put on and with a new screw 31 attached. Here is the outer seal 27 preferably designed to accommodate the room 29 with therein insulating profile 25 covers. On the new pressure profile 28 will be a new cover strip 30 placed.

3 shows the inventive system of elements for the renovation of building facades in post-beam construction for use on horizontal bars in the assembled state, with the comments on the individual elements on the description of 2 is referenced. Good to see is that a bolt chamber 38 arises, which contributes to the insulation of the facade structure against external temperature influences.

The inventive system of elements for the renovation of building facades in post and beam construction is based on the 4 for an existing post shown in an exploded view. The system of elements for posts differs only in small detail from the system of elements for bars, namely in the thickness of the post seal 32 , The lips attached to the post seal 35 include at least the adapter profile 21 and u. U. also a part of the post profile 1 , wherein the projecting from the adapter profile lip end is dimensioned so that the post lips 35 and tie ribs 34 in the assembled state results in a circumferential edge on the facade profiles.

In the 4 elements shown are in 5 again shown in the assembled state. For the section through the post is in addition to those already in 4 elements shown an inserted reinforcing element 36 represented, which serves for the transmission of loads and in 6 is described in more detail.

Depending on the weight of the new facade filling elements 26 in fact, it may be necessary to distribute resulting loads more appropriately, which is why, in addition to the elements mentioned, reinforcing elements 36 be admitted. These are - as in 6 shown - designed as an angle, wherein the vertical in the installed state post legs of the angle along the post profile 1 through the post chamber 37 guided and at the post profile 1 with the help of suitable fasteners, preferably with pins or bolts 39 , z. B. on the old screw holder 4 is attached and the built-in state horizontal locking arm of the angle through the latching chamber 38 to be led.

For load transfer from Fassadenfüllelement on this horizontal, along the bolt extending locking leg of the reinforcing element 36 On the facade construction, it is advisable to also design the locking leg as an angle profile, with a leg in the locking chamber 38 (in 6 not shown) of the bar profile 13 is introduced.

In 7 is the section through a bar profile 13 been selected at a location where the reinforcing element 36 is shown, but in addition also glass holder 40 shown are the load of Fassadenfüllelements 26 on the bar profile 13 pass on. This glass holder 40 are with glass holder screws 41 on the bar profile 13 attached. The reinforcing element 13 is in the bolt chamber 38 ideally, it even fills and fills it. For better illustration is on the inserted insulation profile 25 in the room 29 has been dispensed with.

8th shows a section through a post profile 1 in which the material fatigue of the mullion profile 1 in the area of the old screw receptacle 4 the addition of an adapter profile 21 necessary, which in turn has a new screw holder 42 features. The adapter profile 21 is doing the inner sealant recordings 3 attached to the post profile and has at its the building 2 opposite side adapter connection elements 22 on where the post seals 32 are attached. Incidentally, the structure of the profile is substantially similar to the description of the profile to the 4 and 5 ,

Also for the in 9 The illustration shown is based essentially on the descriptions of the 2 and 3 directed. The only difference here is the use of an integrally formed adapter profile 21 that has a new screw holder 42 has, which in the area of the old screw receptacle 4 for receiving the new screw 31 is provided. The adapter profile 21 is in its width to the width of the bar profile 13 customized.
