DESCRIPTION:
BRIEF SUMMARY
The invention relates to a multipart thermally insulated metal profile for facade structures or roof structures which receives covering panels made of glass or other materials between an interior profile and an exterior profile with interposition of sealing means, while the exterior profile is screwed to insulators let into the interior profile.
Such metal profiles, which are known from German Auslegeschrift No. 2,023,536 and German Offenlegungsschrift No. 3,202,482, have the disadvantage that the insulators extending between the exterior profile and the interior profile have a depth which is a function of the thickness of the covering panels. As a result of this, only a limited insulation coefficient of the metal profiles is obtained, which cannot be further improved by means of the conventional structural features.
The aim of the invention is to provide multipart metal profiles intended for facade structures or roof structures of the type in question with a more favorable heat transfer coefficient, called the k value, than was hitherto possible. It is also proposed to provide these profiles with a discharge for condensation moisture, which is of considerable importance when they are installed horizontally or inclined.
In order to achieve the aim adopted, the invention proposes that the interior profile is composed of a compact profile for the converting panels and a screening panel oriented parallel thereto at an interval on the room side, which are mutually connected by means of insulating bars continuous in the longitudinal direction of the profiles and anchored in respective profile grooves. An advantageous further development of this structural form is obtained if profile members forming lateral water discharge channels facing the covering panels and extending beyond the width of the contact profile are arranged on the screening profile combined with the contact profile to form the interior profile. Better strength characteristics of this profile arrangement can furthermore be achieved in that the screening profile is constructed as a hollow profile. Another measure serving the same purpose may consist in that plastics strips or plastics brackets are fitted into the screening profile, which connect it nonpositively to an additional reinforcing profile.
By virtue of the features of the invention, it has been possible to make available a profile structure which is substantially superior in its k value to all the composite profiles hitherto used in facade construction. A satisfactory discharge of the condensation moisture which may possibly form is provided simultaneously.
Exemplary constructions of the object of the invention are described with reference to the drawing, wherein in detail:
FIG. 1 shows the sectional view of a multipart thermally insulated metal profile for facade structures and roof structures constructed according to the invention and
FIG. 2 shows the sectional view of a similar profile arrangement complimented by a reinforcing profile.
The multipart metal profiles illustrated both in FIG. 1 and in FIG. 2 consist of an exterior profile 1 and an interior profile 2, the connection of which occurs by insulators 4 let into a longitudinal groove 3 of the interior profile 2 by means of screws 5 penetrating the exterior profile 1. By this means covering panels made of glass 9 or other material 10 of a facade structure or roof structure are retained between the exterior profile 1 which carries a masking cap 6 and the interior profile 2 with interposition of sealing means 7 and 8.
According to the features of the invention the interior profile 2 is composed of a contact profile 11 and a screening profile 12 constructed as a hollow profile and oriented parallel thereto at an interval on the room side, which are mutually connected by means of insulating bars 13 continuous in the longitudinal direction of the profiles and anchored in respective profile grooves. As a result of this measure, an additional insulating zone unlimited in its dimensions is created and an extremely favorable k value is ob
