BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a National Phase of PCT/CH88/00151 filed Aug. 31, 1988 and based, in turn, on Swiss application 3419/87 of Sept. 4, 1987 under the International Convention.
Field of the Invention
The invention refers to a sealing device for sealing facades and/or roofs with or without a curvature in their length and width and presenting a fall, i.e. lying in a gradient, whereby they are assembled from numerous elements arranged side by side.
BACKGROUND OF THE INVENTION
In building constructions frequent use is made of prefabricated elements for the skin of the facades and roofs. However, these elements can fulfil their function only if the gaps between the elements are sealed in a manner that permits an easy mounting of the latter whereby the sealing must be durable and easily installed.
OBJECTS OF THE INVENTION
It is therefore an object of the invention to provide a sealing device with prefabricated elements assembled on site in form of a modular system without the necessity of additionally resorting to sealing compounds or bonding agents.
Still another object is to provide the sealing device that becomes nearly independent of meteorological conditions.
SUMMARY OF THE INVENTION
With prefabricated sealing elements, i.e. those made at the factory or workshop, it is not easy to achieve a perfect sealing because on the building site unpredictable tolerances always arise. The invention therefore provides an entire sealing device composed of several parts that complement each other in such a way that whenever a leak occurs in one part (which is mostly the case) another part take up the moisture seeped in and drain it. Besides draining the water, the present invention discloses air conduits coming from the outside and serving for compensating the pressure and for air exchange, so that the formation of condensed moisture between the facade or roof elements to be seated can be avoided.
Furthermore the sealing device should be designed in such a way that it is not only applicable for inclined planar facades or roofs but also can be used without any basic modification also constructions of at least single curvature such as barreled roofs, tunnel vaults and even an constructions of double curvature like hemispherical roofs as frequently used for exhibition pavillons and for the ends of the vaults mentioned above.
The sealing device according to the invention is composed of sealing pieces which are formed of interior or lower sealing portions having means for defining an inner sealing zone between the elements and the rooms of the building delimited by them, as well as by outer or upper portions having means for defining further sealing zones which are arranged one behind the other.
BRIEF DESCRIPTION OF THE DRAWING
The above and other objects, features and advantages of my invention will become more readily apparent from the following description, reference being made to the accompanying highly diagrammatic drawing in which:
FIG. 1 is discloses a view of a cutout of a hemispherical roof on which the individual roof elements are sealed by the device,
FIG. 2 a section through two adjacent construction elements with the sealing device lying in the fall along line II--II;
FIG. 3 is the sealing step element according to FIG. 2 in an enlarged scale;
FIG. 4 is illustrates a section through two adjacent construction elements along line III--III according to FIG. 1,
FIG. 5 an exploded prospective view of the sealing of a main junction,
FIG. 6 a section in the direction of the slope according to line VI--VI in FIG. 5 whereby the parts are presented already in their fully mounted state,
FIG. 7 is a top view of the main junction prior to mounting of the sealing disc, and
FIG. 8 is a top view of a secondary junction in a reduced scale.
SPECIFIC DESCRIPTION
FIG. 1 shows a cutout of a roof which in its entity has a double curvature but is made up of individual planar elements 1, 1a, 1b, 1c. The roof construction as illustrated always has two roof elements 1a, 1b lying in
