Abstract
Abstract Sealing joints for curtain walls consisting of juxtaposed panels mounted in a building framework skeleton are provided which comprise horizontal and vertical joint-sealing members which interengage in an overlapping manner so as to prevent rain from percolating through the wall. The horizontal members have downwardly directed external flaps which overlie the vertical members at cross-over points of the horizontal and vertical members.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
In a curtain wall comprising a plurality of juxtaposed panel means, a plurality of vertical profiled joints, a plurality of horizontal profiled joints, and fixing means maintaining said joints in compression on the exterior edges of said panels, said joints being arranged to form a lattice, the improvement comprising; external flap means provided to each of said horizontal joints with said flap means oriented downwardly, each of said horizontal joints interrupting at least one of said vertical joints and each of said interrupted vertical joints having at least one interruption thereof whereat an upper portion of said interrupted vertical joint overlaps on to the upper edge of the respective horizontal joint means and a lower portion of said interrupted vertical joint means is disposed beneath the respective flap means of said respective horizontal joint means.
Claim 2
Dependent Claim
135 words
In a curtain wall comprising a plurality of juxtaposed panel means, a plurality of vertical profiled joints, a plurality of horizontal profiled joints, and fixing means maintaining said joints in compression on the exterior edges of said panels, said joints being arranged to form a lattice, the improvement comprising; external flap means provided to each of said horizontal joints with said flap means oriented downwardly, each of said horizontal joints interrupting at least one of said vertical joints and each of said interrupted vertical joints having at least one interruption thereof whereat an upper portion of said interrupted vertical joint overlaps on to the upper edge of the respective horizontal joint means and a lower portion of said interrupted vertical joint means is disposed beneath the respective flap means of said respective horizontal joint means.
Claim 3
Dependent Claim
53 words
System of sealing joints as claimed in claim 1, wherein at the position of crossing with each vertical joint each horizontal joint is grooved in its lower part situated beneath the flap means so as to allow the arrangement of the corresponding lower interrupted extremity of said vertical joint beneath said flap means.
Claim 4
Dependent Claim
64 words
System of sealing joints as claimed in claim 1, wherein each joint is maintained in compression on the curtain wall by means of a rigid maintaining bar which is fixed by screwing on to the skeleton framework supporting the curtain wall and which extends as far as the position of crossing of this joint with each of the joints which are perpendicular to it.
Claim 5
Dependent Claim
31 words
System of sealing joints as claimed in claim 3, wherein each fixing means comprises a theaded element passed through a hole in the maintaining bar and serewed into tho skeleton framework.
Claim 6
Dependent Claim
53 words
System of sealing joints as claimed in claim 3, wherein that portion of the bar which corresponds to each of said lower interrupted extremities of the vertical joint slightly prolongs said extremity upwards in such a way as to be applied to the ungrooved part of the horizontal joint corresponding to that extremity.
Claim 7
Dependent Claim
34 words
System of sealing joints as claimed in claim 3, wherein each profiled joint has at least two lips separated by a central part against which the maintaining bar of the corresponding joint is applied.
Claim 8
Dependent Claim
33 words
System of sealing joints as claimed in claim 3, wherein the central part of each vertical joint is hollow in order to form an internal space able to receive the corresponding maintaining bar.
