DESCRIPTION:
BRIEF SUMMARY
The invention relates to a curtain wall panel with sealing system, a sealing system, and respective sealing sections.
In curtain walls it is common to provide, between two panels, on the one hand an inner seal, on the other hand an outer seal.
The inner seal is generally ensured by means of two identical tubular sections, of rubber or the like, or thermoplastic product, which take support on one another, laterally, when each panel is positioned. These tubular sections, worked in the form of frames whose angles are vulcanized in a specific manner in view of the tubular geometry of these sections, are disposed beforehand on the circumference of a carpenter's bench, whether of metal or not, before this bench is positioned. The outer seal is generally ensured by a section of rubber or the like, or thermoplastic product, with V-shaped throat, running vertically and horizontally on the face of the curtain wall, to cover up all lines of separation between adjacent panels. To assure a good seal at right angles with the zones of juxtaposition of four adjacent panels, it is desirable to arrange in these zones molded connecting pieces between running sections, which comprise a deformation chamber, for example with bellows, in order to absorb the deformations due to the variations in relative position of the panels. These connecting pieces are prefabricated. They are connected by gluing for example, on the face itself. It is therefore necessary to position them on the outside of the face, by means of a "balancelle". This operation takes time and requires relatively costly means, in men and in material.
One of the objects of the present invention is to propose a curtain wall panel with sealing system which avoids any problem of deformation in the zones of juxtaposition of four adjacent panels.
Another object of the invention is to avoid any intervention on the face after the positioning of the panels.
The invention relates to a curtain wall panel with sealing system, of the type in which the sealing system, installed before the positioning of the panel, consists of an outer continuous sealing barrier and an inner continuous sealing barrier, characterized in that the sealing barriers are each formed by sealing sections presenting a small width on two adjacent sides of the panel and a large width on the other two adjacent sides of the panel, in such a way that, as the positioning of a panel occurs by a movement perpendicular to the plane of the panel, the seal packages of two adjacent panels bear on each other laterally.
According to other characteristics of the invention: cross section; U-shaped section with one long and one short lip;
The invention also relates to a sealing system for curtain walls, of the type comprising an inner seal and an outer seal, both formed by elastically deformable sections, characterized in that one of the continuous sealing barriers, outer or inner, consists of a U-shaped section comprising a long lip and a short lip so that, as the positioning of a panel is done by a movement perpendicular to the plane of the panel, the long and short lips of the positioned panel rest laterally, respectively, on the short and long lips of the adjacent panel already in place.
According to other characteristics of the invention: curtain wall, and installed at the factory so that the positioning of the panel on the construction site ensures correlatively the positioning of the two, outer and inner, sealing barriers; attachment and two lips, one long and the other short, so that the face-to-face arrangement of two actually symmetrical sections ensures the tightness by reciprocal support of their long and short lips respectively; turned-up fins, the hook-on foot being maintained under the turned-up fins by shoulders, the lips present a rear shoulder bearing against the fins of the metal section; fins of the metal section; toward the inside, and on the other two sides it is placed with the long lip toward the outside; of the panel, by a short section, and on the other two sides, by a long section; whose corners
