The invention relates to a sealing piece for sealing a T connection between a post profile and a transom profile, in particular for mullion-transom constructions of facades, light roofs and winter gardens. The invention also relates to a post-and-bar construction with such a sealing piece.

From the EP 1 223 257 A1 a mullion and transom construction is known which contains post profiles and transom profiles connected to one another at right angles. To seal the connection between the mullion and transom profiles, a sealing piece is provided which, with its end face facing the transom profile, rests against a glass support or a screw groove of the transom profile and is flush with it. The end face of the sealing piece facing the locking profile protrudes over the side of the post profile facing the locking profile, so that in the assembled state the end face rests against the glass support or the screw groove and the front face of the locking profile and seals it. As a result, the drainage grooves provided on the transom profile are lengthened so that no moisture can get between the transom profile and the sealing piece. On the sealing piece, mutually right-angled sections for engaging in anchoring grooves of the locking profile and a groove of the post profile arranged adjacent to the locking profile are arranged. The sealing piece also has a recess to extend the drainage groove of the locking profile.

This object is achieved by a sealing piece with the features of claim 1 and by a post-and-bar construction with the features of claim 14. Appropriate Further developments and advantageous embodiments of the invention are the subject of the subclaims.

The sealing piece according to the invention has a cover body designed to overlap the post profile and the transom profile with an inner sealant receiving space that can be filled from the outside by a sealant. As a result, silicone or another viscoplastic sealant, for example, can get to the joint area between the post profile and the transom profile in a particularly effective way and ensure an optimal sealing of the entire intersection area there.

In an advantageous embodiment, the cover body of the sealing piece can be a hat-shaped cover body designed as a hollow body. In a particularly expedient embodiment, the cover body contains a rear area for placing on the transom profile and a front area for covering the post profile. In an advantageous embodiment, the sealing piece has an inclined end face on the front area of the cover body which is provided with an opening for introducing a sealant into the sealant receiving area. The cover body has a slimmer upper part and a widened lower part. At the transitions from the slimmer upper part to the widened lower part, upper surfaces are expediently arranged with areas sloping backwards. Over the surfaces with the areas sloping backwards at an angle, water that collects in the drainage channels of the transom profiles can be conducted over webs of the post profile into the drainage channels of the post profile.

The sealant receiving space can be formed by a supply channel, in particular by a supply channel connected to an opening for introducing a sealant, in the slimmer upper part of the cover body and a recess connected to the supply channel on the underside of the widened lower part of the cover body. The recess can extend between a rear edge of the cover body and a front transverse web, in particular a front transverse web provided for engaging in a receiving groove of a post profile. The depression preferably runs on both sides of the lower part of the widened compared to the slimmer upper part Cover body, and particularly preferably over almost the entire length of the rear region of the cover body up to the supply channel arranged in the front region.

A first transverse groove for receiving an inner web is expediently arranged in the cover body on the side of the post profile facing the transom profile. In addition, a second transverse groove for receiving an outer web on the side of the post profile facing the transom profile is provided in the cover body.

In a further advantageous embodiment, a web-shaped holding element for engaging in a receiving channel of a fastening web arranged on the locking profile can be formed on the cover body of the sealing piece. Toothings or hook-shaped projections for locking engagement in the receiving channel can be provided on the holding element. By means of the holding element, the sealing piece can also be securely held on the transom profile when the sealant is introduced.

The cover body expediently consists of a transparent or translucent material. In this way, the degree of filling with the sealant can be determined and the correct filling can be checked. The cover body can also consist of EPDM or a non-transparent or translucent material.

The cover body is preferably designed to accommodate sealing profiles. In a further expedient embodiment, sealing elements, in particular sealing elements designed as sealing corners with sealing strips angled to one another, can also be molded directly onto the cover body.

A mullion and transom construction according to the invention is characterized in that the connection between the post profiles and the transom profiles is sealed by a sealing piece described above. The sealing piece can also be used to seal off screws or other fastening elements of the T connection between the post profile and the transom profile.

In the Figures 1 and 2 is a first embodiment of a T-connection between a post profile 1 and a transverse transverse transverse profile 2 of a post-and-beam construction for facades, winter gardens, light roofs and the like. Shown in various representations. The two post and transom profiles 1 and 2 can have the same or a different cross section. In the embodiment shown, the post and transom profiles 1 and 2 are designed as hollow profiles with a cavity 3 and an identical cross section. They each have two side walls 4 and 5 parallel to one another and two inner and outer end walls 6 and 7 at right angles to the side walls 4 and 5. The outer end wall 7 facing the outside of the mullion and transom construction contains an outwardly protruding fastening web 8 with a receiving channel 9 open to the outside for fastening screws or other fastening elements, through the holding profiles (not shown here) or a holding structure for holding glass panes or other facade elements be attached to the outer end wall 7 can. To the right and left or above and below the fastening web 8 are on the outside of the outer end wall 7 also in the longitudinal direction of the post or transom profile 1 or 2 extending grooves 10 for receiving sealing pieces 11 and in Figure 2 Seals 12 shown are provided. The grooves 10 for the seals 12 are delimited by outer and inner webs 13 and 14, respectively. Drainage channels 15 are arranged between the inner webs 14 and the central fastening web 8.

In the embodiment shown, the post profile 1 and the transom profile 2 are designed in the form of a metal profile tube made, for example, by an extrusion process, which can consist of steel or aluminum. But they can also be made as a welded construction from a correspondingly bent and welded sheet metal, as a wood or plastic construction or the like. The outwardly protruding fastening web 8 on the outer end wall 7 facing the outside and serving to fasten glass panes or other facade elements has, in the embodiment shown, a receiving channel 9 designed as a screw channel. Fastening screws provided with a cutting thread for fastening retaining profiles or other supporting or facade elements can be screwed into the receiving channel 9, for example.

The connection between the post profile 1 and the locking profile 2 can be made by a connector (not shown here) which is inserted into the cavity 3 of the locking profile 2 and contains connecting elements designed as an insertion profile and locking bolt for form-fitting engagement in the post profile 1.

That in the Figures 3 to 6 Sealing piece 11, shown separately in different views, is designed to seal the T-joint between the post profile 1 and the transom profile 2. It is placed on the post-and-beam construction from the outside and enables the T-joint to be sealed against water and steam. For this purpose, the sealing piece 11 has a hat-shaped cover body designed as a hollow body with a rear region 16 for placing on the transom profile 2 and a front region 17 for covering the post profile 1.

How special Figure 6 As can be seen, the rear area 16 of the hat-shaped cover body is designed to be placed on the fastening web 8 of the locking profile 2, while the front area 17 of the cover body engages over the post profile 1 and on its underside two parallel transverse grooves 18 and 19 for receiving the receiving groove 10 for the seal 12 delimiting inner and outer webs 13 and 14 on the side of the post profile 1 facing the transom profile 2.

The cover body that can be slipped onto the post profile 1 and the transom profile 2 has a slimmer upper part 20 and a widened lower part 21. A first transverse groove 18 for receiving the inner web 14 on the side of the post profile 1 facing the transom profile 2 is arranged in the lower part 21 on the front region 17. In the lower part 21 of the sealing piece 11, a second transverse groove 19 parallel to the first transverse groove 18 is also arranged on the front area 17 for receiving the outer web 13 on the side of the post profile 1 facing the transom profile 2. In the rear region 16 of the sealing piece 11, lateral recesses 22 are also provided in the lower part 21 to cover screws or other holding elements.

In Figure 3 it can be seen that the sealing piece 11 has two upper surfaces 23 with regions 24 sloping towards the rear at the transitions from the slimmer upper part 20 to the wider lower part 21. Via the surfaces 23 with the inclined areas 24, water collecting in the drainage channels 15 of the transom profiles 2 can be conducted over the webs 13 and 14 of the post profile 1 into the drainage channels 15 of the post profile 1. At the front ends of the sealing piece 11 facing the post profile 1, the surfaces 23 are delimited by upwardly projecting, lateral front delimiting webs 25. At the end of the rearwardly sloping regions 24, lateral rear delimiting webs 26 are arranged. A front end face 27 of the upper part 20 pointing towards the post profile 1 is formed at an angle and has an opening 28 for introducing a sealant. The sealant can be, for example, silicone or another tough elastic sealant.

the end Figure 4 It can be seen that the sealing piece 11 on the inside of its rear region 16 which can be placed on the fastening web 8 of the locking profile 2 contains a groove-shaped receiving region 29 running in the longitudinal direction of the sealing piece 11 for receiving the fastening web 8. The width of the groove-shaped receiving area 29 is matched to the width of the fastening web 8. The cover body of the sealing piece 11 also has an inner sealant receiving space on its inside for receiving the sealant that can be supplied from the outside via the opening 28. The sealant receiving space is formed by a front feed channel 30 arranged in the front area 17 of the cover body and a recess 31 connected to it, which is located on the underside of the cover body on both sides of the groove-shaped receiving area 29 over almost the entire length of the rear area 16 up to Feed channel 30 runs in the front region 17. The sealant can thus reach the recess 31 on the underside of the widened lower part 21 through the opening 28 and the supply channel 30.

On the cover body of the sealing piece 11, a web-shaped holding element 32 protruding into the receiving area 29 for engagement in the receiving channel 9 of the fastening web 8 is integrally formed. Are on the web-shaped holding element 32 in Figure 5 recognizable teeth or hook-shaped projections 33 are provided for locking engagement in the receiving channel 9 of the fastening web 8. By means of the holding element 32, the sealing piece 11 can also be securely held on the transom profile 2 when the sealant is introduced.

From the Figures 7 to 10 it can be seen that the in Figure 7 recognizable supply channel 30 and the recess 31 between an in Figure 4 rear edge 34 shown and a transverse web 35 engaging in a receiving groove 10 of the post profile 1 can be filled with a sealant, shown here by a grid of points. As a result, the sealant supplied via the opening 28 can not only get into the transom profile 2, but also into the post profile 1. The in Figure 4 The recognizable transverse web 35 is angled at its ends and has end-side closing webs 36 adapted to the width of the receiving groove 10 of the post profile 1. This can prevent the sealant located in the depressions 31 from reaching the receiving groove 10 of the post profile 1 beyond the sealing piece 11 to the outside. The groove-shaped receiving area 29 has a somewhat larger width than the fastening web 8, so that a gap remains between the outside of the fastening web 8 and the groove-shaped receiving area 29. About this gap, the sealant can according to Figures 8 to 10 from the depressions 31 on the outside of the fastening web 8 along to the receiving channel 9 on the top of the fastening web 8 and into the receiving channel 9 down to the bottom thereof. In this way, an optimal seal can be achieved.

The cover body of the sealing piece 11 is preferably made of plastic. The cover body particularly preferably consists of a transparent material. In this way, the correct filling of the cover body with sealant can be checked. About the sealing piece 11 can also be in the Figures 1 and 6th Not shown screws or other fastening elements of the T-connection between the post profile 1 and the transom profile 2 are sealed.

In the Figures 11 to 21 a further embodiment of a T-connection between a post profile 1 and a transverse transverse transverse profile 2 of a post-and-rail construction with an alternative sealing piece 11 is shown. In this embodiment, sealing elements 37 made of EPDM for engaging in the receiving grooves 10 of the post profile 1 and transom profile 2 are molded onto the hat-shaped cover body, which is also provided with a narrower upper part 20 and a wider lower part 21. The sealing elements 37 have sealing strips 38 and 39 which are at right angles to one another. The sealing strips 38 and 39 can also be arranged at an angle. According to Figure 12 Corresponding strip-shaped sealing profiles 40 can be connected to the sealing strips 38 and 39. The sealing profiles 40 can be placed flush or can be firmly connected to the sealing strips 38 or 39, for example by gluing.

the end Figure 14 It can be seen that the transverse web 35 in the lower part 21 of the plug-on body, in contrast to the exemplary embodiment described above, does not contain any lateral end webs 36. The sealant receiving space formed by the feed area 30 and the depressions 31 is thus open towards the sealing elements 37, so that a sealant supplied via the opening 28 can also reach the sealing elements 37. Otherwise, the two exemplary embodiments are constructed similarly, so that parts that correspond to one another are also provided with the same reference numerals. Reference is made to the corresponding description of the first exemplary embodiment.
