DESCRIPTION:
BRIEF SUMMARY
The present invention pertains to a cladding element for outer facades of buildings and to the application thereof for cladding the said facades. It also pertains to an embossing apparatus for cladding elements, especially when they are used for siding panels.
The outer heat insulating systems are insulation systems in which the insulating material is disposed on the outer facade of the outer walls of a building, i.e., on the outer concrete or masonry walls.
Insulating cladding is in an increasingly important place among the outer heat insulating systems currently used.
It should be recalled that an insulating cladding is an outer cladding formed by the assembly of prefabricated units which combine an insulating material and an outer shell, the said units being glued and/or attached mechanically to the support wall.
In the Austrian Pat. No. 323,964 there is described a cladding formed by complex elements each comprising a core consisting of insulating material, incorporated in an outer shell formed by a panel consisting of a section made of a thermoplastic material. On its face in contact with the panel the core made of insulating material has embossed parts forming spacers for a narrow air gap. The panel consists of a flat central band edged on each lateral side by a flange. One of the said flanges is extended by a folded-back part directed toward the inside of the panel and is practically parallel to the central band in such a way as to form a hook whereas the other edge is extended by a wing directed towards the outside of the panel and is practically parallel to the central band. The said wing is provided with holes for fixing screws for attaching the panel to the support, and it also has, at its end, a folded-back part disposed on the side of the central band is practically parallel to the latter, the said folded-back part forming a hook complementary to that formed by the part forming the extension of the other flange of the panel. The connection between the two adjacent panels is achieved by engagement of the folded-back part forming an extension of one of the flanges of the panel with the part folded back in a complementary fashion on the end of the wing of the adjacent panel.
A primary inconvenience of this type of cladding lies in the fact that the connection means of the panels do not permit interlocking of the panels with each other, which involves the risk of unhooking of downward stress due to wind.
A second inconvenience arises from the fact that no means are provided for evacuating the condensation products, and that, even though there is aeration between the insulating core and the panel due to the narrow air gap provided by the embossed parts, it is nonetheless true that the ventilation or the renewal of the air is not satisfactory.
A third inconvenience lies in the fact that the fixing heads of the panels on the support are not protected from bad weather.
Finally, a fourth inconvenience arises from the difficulty of placing the cladding elements, e.g., in the vertical U-shaped fastening squares around openings such as windows and doors.
The present invention has the task of eliminating these inconveniences and to propose a cladding element that is suitable for use as a panel for a cladding that can be attached to the support wall both horizontally and vertically.
It also pertains to a means permitting the placement and fixation of the cladding elements on the support walls enclosing a re-entrant or salient angle with other support walls without the appearance of discontinuities. The means according to the present invention also permit the connection of parts of the cladding at the openings as may be present in the support wall.
Finally, it also pertains to a panel embossing apparatus which confers an outer embossed appearance, e.g., a conventional painted appearance, to the said panel.
To achieve this, the cladding element according to the present invention, which is made by extrusion from a thermoplastic material, particularly polyvinyl chloride, and which comprises a central band edged
