Abstract

A building system integrating the combination of aluminum and steel structural elements for the efficient assembly of stone and glass panels in a curtain wall system which is conspicuous for its lack of a grid appearance. A plurality of discrete steel clips are utilized for securing stone panels to supporting mullions. A plurality of aluminum members are secured to structural mullions whereby glass may be mounted thereto. The stone and glass panels are sealably secured adjacent one another while a glazing adapter is constructed for assembly over the structural mullions there behind. A splice facilitates mating engagement of the aluminum mullions to permit relative movement therebetween. In this manner, both steel and aluminum may be utilized most efficiently for the assembly of stone and glass panels in a curtain wall system with improved structural and aesthetic qualities.

Dependent claims

A combination stone and glass curtain wall system comprising:

a structural wall section including a plurality of generally vertical steel mullions disposed one from the other in generally parallel spaced relationship;
a plurality of discrete, horizontal steel clips adapted for securement to said vertical steel mullions in generally parallel spaced relationship one to the other and in generally orthogonal relationship relative to said vertical steel mullions;
means for securing said descrete horizontal steel clips to said vertical steel mullions;
means associated with said discrete horizontal steel clips for securing said stone thereto;
a plurality of horizontal aluminum mullions adapted for securement to said vertical steel mullions in generally parallel spaced relationship one the other and in generally orthogonal relationship to said vertical steel mullions;
means for mounting said horizontal aluminum mullions to said vertical steel mullions;
said horizontal aluminum mullions being disposed adjacent to said discret horizonatal steel clips in generally parallel spaced relationship thereto for the securement of glass in direct association with stone supported thereby;
and
means for sealably securing said stone and said glass adjacent to one another in said curtain wall.

6 more elements

An improved method of manufacturing a glass and stone curtain wall of the type wherein both glass and stone panels are secured to a common curtain wall with said glass panels being disposed adjacent said stone panels in at least one select area thereof, wherein the improvement comprises the steps of:

providing a structural framework including a plurality of vertical steel mullions disposed in generally parallel spaced relationship one from the other;
providing a plurality of horizontal steel clips adapted for securement to said vertical steel mullions and the support of said stone panels;
securing said horizontal steel clips to said vertical steel mullions;
providing a plurality of horizontal aluminum mullions adapted for securement to said vertical steel mullions and the support of said glass panels;
securing said horizontal alumunum mullions to sid vertical steel mullions in generally parallel spaced relationship and in an orientation generally orthogonal to said vertical steel mullions;
mounting said stone panels to sid horizontal steel clips;
and
mounting said glass panels to said horizontal aluminum mullions.
