  • Component 1040 is connected to transom 1026 by an interlocking connection 1050 between component 1040 and the metal structure so as to cover an entirety or substantially an entirety of the outer side 1028 of transom 1026 (i.e., the entirety of a width of transom 1026).
  • interlocking connection 1050 is formed by longitudinal insertion of component 1040 within structural channel 1032 (and/or within second structural channel 1034 and/or third structural channel 1038).
  • Component 1040 is connected by press-fitting component head 1042 longitudinally into the channel 1032 and sliding component 1040 along a length of transom 1026.
  • Component 1040 includes an integrally connected stem 1080 projecting into a space between a first panel 50 and a second panel 50 of the curtain wall or window wall system.

  • Pressure plate 1008 applies pressure against seals which in turn press against panels 50 to securely hold the panels 50 into position.
  • a gap between pressure plate and a terminal end of component 1040 allows fastener 39 to induce a pressure against the plate 1008 when fastener is tightened.
  • a downward force caused by the weight of panel 50 in turn imparts an outward pulling force upon component 1040, which is resisted by interlock 1050 or a series of similar interlocks.
  • Structural head 1030 friction fits within component channel 1044.
  • the outward pulling force causes second component head 1043, for instance, to press against or more firmly press against an outermost inward facing surface 1031 of structural head 1030.

  • the interlock 1050 is created when the component heads 1042, 1043, 1045 of component 1040 are slid longitudinally into structural channels 1032, 1034 and 1038 (and/or when the simultaneous sliding of structural heads 1030, 1036 into component channels 1044, 1046).
  • the component 1040 is connected to the metal structure at the outer side 1028 solely by the interlocking connections.
  • Such exclusively interlocked connection provides an effective thermal barrier and insulation of the outer surface of the transom or mullion structure.
  • interlock or interlocks are formed upon longitudinally sliding a structural head of the metal structure within a component channel of the component.
  • the structural head has a T-shaped transverse cross section that extends lengthwise along the meal structure and within the component channel, the component channel having a corresponding T-shaped cross section to receive the head.
  • the interlocks 1050 include four separate inward facing surfaces 1031 against which an outward-pulling component 1040 is locked. Moreover, given the snug fit of the T-shaped structural heads 1030, 1036 within the corresponding T-shaped component channels 1044, 1046, and the snug fit of the component head 1042, second component head 1043 and third component head 1045 against respective channel structures, rotation or detachment of component 1040 from wall 1027 is prevented.
  • the fiber-reinforced polymer component 1040, including the component head 1042 and component channel 1044 structures for instance, has a strength sufficient to provide structural support of panel 50, including the support necessary to accommodate for environmental forces or loads due to high winds or other environmental factors.
  • Component 1040 is devoid of penetrations from an outside to an inside of the component.
  • Slot 1010 extends only partially inward (and not entirely through component 1040) to assure a sufficient isolation of metal fastener 39 from metal wall structure 1034.
  • Slot 1010 is preset to accommodate insertion of fastener 39 without cracking or undue damage to component 1040 and to provide centering alignment during installation.
  • slot 1010 extends longitudinally the length of component 1040.
  • component 1040 is sized lengthwise to match the length of metal structure of transom 1026, and in some instances transom 26 spans several feet, such as 4 to 8 to 25 feet or greater.
  • the interlocks 1050 span the length of transom to provide a solid connection along the entire length of the structure.
  • Transom 1026 is configured for use on a curtain wall or window wall system.
  • FIG 34 is a section view of a mullion structure according to a further aspect of the invention.
  • Mullion 1024 includes a first mullion segment 1025 connected to a second mullion segment 1029. Segments 1025, 1029 are made of metal and fit together lengthwise to form a solid structural mullion support.
  • An interlock 1050 is formed between segment 1025 and first fiberglass reinforced polymer component 1040. Interlock 1050 at mullion 1024 is the same, similar or substantially the same as interlock 1050 at transom 1026.
  • a structural head 1030 projects from wall 1027 and into a component channel 1044.

  • Component 1040 includes stem 1080 which extends between opposed panels 50 and includes a preset slot 1010 to receive fastener 39. Fastener 39 inserts through pressure plate 1008 and into slot 1010 to apply pressure against seals 60 which in turn apply pressure against panels 50 for secure positioning.
  • Component 1040 is configured to cover an entirety or substantially an entirety of an outer side 1028 of segment 1025.
  • component 1040 is configured to structurally support a panel 50 of a curtain wall or window wall system. A spacer may be inserted between panel 50 and stem 1080.

  • component 1041 abuts component 1040.
  • component 1041 is a fiberglass reinforced polymer.
  • Component 1040 and 1041 together operate to completely cover, or at least substantially cover, the outer side 1028 of mullion 1024.
  • a seal in one aspect is provided between component 1040 and an inward facing surface 1031'.
  • a portion of second component 1041 is positioned between first component 1040 and a terminal edge of outer wall 1027'.
  • component 1040 is connected to segment 1025. Seals are then added. Component 1041 is connected to wall 1027', and then segment 1029 is connected to segment 1025 lengthwise along their lengths. Such lengthwise connection creates a solid structural member for use in a curtain wall or window wall system. Component 1040 and segment 1025 are connected by longitudinally sliding them together, with structural head 1030 sliding within component channel 1044 to form an interlocking connection 1050.
  • interlocking connection 1050 or multiple such interlocking connections 1050, is the sole connection necessary to connect the component to the metal structure.
  • seals are positioned within seal receivers of components 1040, 1041 which abut against inside surfaces of respective panels 50, 50.
  • the longitudinal sliding connection of component 1040 and segment 1025 creates a friction fit among the surfaces of the T-shaped elements. Because the components 1040 and segments 1025 are or can be very long, a significant amount of pressure in some instances is required to longitudinally press-fit the parts together.
  • the tolerances between surfaces of the respective T-shaped elements can be varied to adjust the relative force (and resulting tension of friction fit) needed or used to longitudinally slide the parts together.
