Abstract
A curtain wall systems includes a joint member having a formation adapted to be secured to a mullion and a projection arranged to extend horizontally of the joint member in use and dimensioned to be received within a transom. Bearing surfaces of the projection are coated with a low friction material such as polypropylene and arranged so that the transom may more relative to the joint upon thermal expansion or contraction.
Claims10
A curtain wall system, comprising;
- a vertical member;
- a joint member including means for fastening said joint member to said vertical member and a projection member extending transversely to said vertical member in a horizontal orientation and having bearing surfaces extending horizontally;
- a horizontal member of extended length, said horizontal member being contoured in cross-section to slidingly receive and retain said projection member telescopically and at least partially within said horizontal member in the length direction of said horizontal member;
- and
- a low friction layer portioned on the bearing surfaces of said projection member for facilitating sliding motion between said projection member and said horizontal member, said horizontal member and said joint member being subject to relative motion upon thermal expansion or contraction of the horizontal member.
