(5) FIG. 4 shows a diagram of a sealing element, which is constructed as a lower corner, for a facade element,

(6) FIG. 5 shows a rearward diagram of the same sealing element,

(7) FIG. 6 shows a side view of the same sealing element,

(8) FIG. 7 shows a horizontal section through two mutually adjacent sealing elements,

(9) FIG. 8 shows a schematic diagram of the assembly of a suspended facade of facade elements working from left to right,

(10) FIG. 9 shows a schematic diagram of the assembly of a suspended facade of facade elements working from right to left,

(11) FIG. 10 shows a diagram of two mutually adjacent sealing elements and

(12) FIG. 11 shows a front view of a facade member with two sealing elements in installed state.

(13) A sealing element, which as seen from the outside is provided as an upper left corner for a facade element, is denoted by 1 in FIG. 1.

(14) In the case of suspended facades, distinction is usually made between element facades and post-and-rail facades. Element facades are composed of individual facade elements which are suspended at suspension means at the building, preferably at the building roof. For that purpose, the facade elements are mounted on the building with, for example, the help of a crane, in that each element is attached to an already mounted neighbouring element or element arranged thereunder. The mode of working can in that case be from left to right or from right to left, as illustrated by FIGS. 8 and 9.

(15) In the case of element facades, water can penetrate or condensate can form at different places.

(16) Both have to be conducted away to the outside.

(17) The sealing element 1 according to the invention is provided for that purpose.

(18) The sealing element 1 is constructed from a connecting flange 2 and a sealing lip 3 arranged thereat.

(19) The connecting flange 2 nests against the side edge of the facade element. The inwardly bent sealing lip 3 is arranged at its front edge.

(20) When assembling the facade elements to form a facade, two sealing lips 3 of adjacent facade elements abut one another and thus ensure sealing of the facade elements relative to one another.

(21) In this embodiment, the connecting flange 2 is led around the corner of the facade element and is suitable for the upper lefthand corner of the facade element.

(22) Provided for the other corners of the facades elements are identical variants, which are adapted to the respective corner, of the sealing element 1, as shown in, for example, FIGS. 4, 5 and 6. A lower lefthand corner is illustrated there.

(23) The sealing lip 3 similarly extends over the corner.

(24) A lip 4 is provided at the vertical section of the connecting flange 2 and, as seen from the front, rises at an inclination in rearward direction and extends over substantially the entire depth of the connecting flange 2.

(25) It is conceivable for the lip 4 to be shorter or longer than the depth dimension of the sealing element.

(26) The depth of the connecting flange 2 is matched to the depth of the facade element and usually corresponds therewith.

(27) In addition, a recess 5 through which the lip 4 can project is provided in the sealing lip 3, as illustrated in the present embodiment.

(28) However, it is also conceivable for the lip 4 to be flush with the sealing lip 3.

(29) Water or condensate present in the intermediate space between two facade elements is conducted away outwardly over the lip 4 in accordance with gravitational force and can then drip off in front of the facade or run downwardly thereat.

(30) For that purpose, the lip 4 forms a channel in which the water or condensate is conducted away.

(31) In the case of assembly of several facade elements, adjacent lips 4 abut one another or also mutually overlap.

(32) In both cases a channel can thereby be formed. The lips 4 then have a curved or angled cross-section. It is also conceivable for each lip 4 to form an individual channel.

(33) The lip 4 extends so as to rise at an angle in inward direction. The angle of inclination is in that case between 30 and 70 relative to the horizontal, preferably between 35 and 60. Particularly good results were achieved with an inclination of about 40.

(34) In that case, deposit of drops of water by adhesion to the lip 4 and thus creation of build-ups are prevented.

(35) In addition, any dirt which may have penetrated is flushed away with and at the time of outflow of the water or condensate, since the flow speed is sufficiently high.

(36) The recesses 5 are so adapted with respect to the size thereof that water does not build up due to surface tension, but is directly conducted away.

(37) A connection, which is not illustrated here, can be provided between two sealing elements 1 of a facade element. This will advantageously connect the connecting flanges 2 and provide a connection of the sealing lips 3. The sealing lips 3 are then formed over the full length of the connection.

(38) By contrast, the connection of the connecting flange 2 can be executed with, for example, reduced depth.

(39) A frame which embraces the respective facade element is formed by the connections of several sealing elements.

(40) In that case, sealing elements 1 can be provided in all corners of the facade element.

(41) Discharge of penetrated water and condensate can thus be ensured at all corners particularly in the case of larger facades, so that the amount of water and condensate present in the intermediate spaces does not increase too strongly and possibly force the liquid onto the inner side of the facade.

(42) The sealing element can be attached to the facade element prior to installing the facade element to a building and the sealing element is a monolithic element.
