Description




BACKGROUND




The disclosures herein relate generally to space frame structures, and in particular to cladding for domed space frame structures.




In space frame construction, a generally cylindrical hub includes a plurality of outwardly directed slots extending along the peripheral surface of the hub. The slots have opposed ribbed surfaces. Tubular frame members are flattened and crimped at their opposed ends. The crimped ends include elongated flat surfaces extending outwardly, or away from each other. The crimped ends are ribbed in a pattern which can be mated into engagement with the ribs in the hub slots. In this manner, each end of a tubular frame member may be slidably inserted into a respective hub slot and several tubular members may be connected at one end to a hub slot to form a spider, i.e., a hub having a plurality of tubes extending outwardly therefrom, each tube terminating at a free end.




The free end of each tube can be similarly connected to another hub. Thus, a framework of interconnected spiders formed of tubes and hubs can be joined to form a pre-assembled or modular section of a flat roof, a domed roof, a wall, etc., to be joined with other sections to eventually form a complete structure. The structure, once completed is then covered with a selected cladding which is attached to the structural framework by means of an interfacing cladding support system.




The cladding may be fabric, corrugated steel plates, glass, and other selected materials, and may include combinations of these materials for architectural design purposes. For example, a domed roof may be clad with steel and may include a pattern of glass panels in a portion of the roof which has an aesthetic effect when viewed from the interior of the structure.




However, in constructing domed space-frame structures having a plurality of roofing areas that include doubly curved surfaces, of positive and/or negative gaussian curvature, it is difficult to cover such surfaces with conventional rectangular cladding panels without gaps of variable width occurring between the cladding panels.




Therefore, what is needed is a cladding system for domed structures directed to overcoming one or more of the limitations of the existing structures.




SUMMARY




One embodiment, accordingly, provides a building that includes a support structure, a first panel coupled to the support structure, a second panel coupled to the support structure, wherein at least a portion of the second panel is separated from the first panel by a gap, and a bridge coupled to the support structure and the first and second panels, wherein the bridge includes: a cover, and a clip nested within the cover, wherein the cover bridges the gap.




A principal advantage of this embodiment is that it permits a domed structure to be covered in a manner which avoids the limitations presently associated with cladding such structures.

DETAILED DESCRIPTION




A cladding system for a domed structure is provided that permits gaps between adjacent roofing panels to be bridged without the use of custom made bridging panels of variable size. In a preferred embodiment, the cladding system bridges variable gaps between adjacent roofing panels positioned on a doubly curved surface. In this manner, the construction of a domed structure is simplified.




A cladding system for a domed structure is also provided that utilizes roofing overlapping roofing panels coupled by an adhesive layer. In this manner, a watertight roofing system is provided without having to utilize custom fabricated roofing panels.




Referring initially to

FIGS. 1 and 2

, a doubly curved surface


100


is illustrated that includes a number of individual sections


105




a


and


105




b


. The doubly curved surface


100


is typical of surfaces found in domed structures. The doubly curved surface


100


has positive gaussian curvature. Alternatively, the doubly curved surface


100


could have negative gaussian curvature. Therefore, persons of ordinary skill in the art will recognize that the doubly curved surface


100


is representative of the outline shape of a domed structure.




In order to provide a roofing system for such a domed structure, it is conventional to provide an underlying support structure, and then clad the underlying support structure with a number of roofing panels


110




a


and


110




b


. Such conventional roofing panels,


110




a


and


110




b


, typically consist of long rectangular panels. When such panels,


110




a


and


110




b


, are placed on a doubly curved surface


100


, a variable gap, G, results between the adjacent ends of the panels,


110




a


and


110




b.






For a doubly curved surface having positive gaussian curvature, if the ends of the panels,


110




a


and


110




b


, are positioned in contact, the gap between the panels,


110




a


and


110




b


, increases in size towards the middle portion of the panels,


110




a


and


110




b


. Conversely, for a doubly curved surface having negative gaussian curvature, if the centers of adjacent side of the panels,


110




a


and


110




b


, are positioned in contact, the gap between the panels,


110




a


and


110




b


, increases in size towards the end portions of the panels,


110




a


and


110




b.






Referring to

FIGS. 3 and 4

, one conventional method for bridging the gap, G, between adjacent roofing panels,


110




a


and


110




b


, on a doubly curved surface includes the use of custom made roofing panels,


300


and


400


. The custom roofing panel


300


is adapted to bridge the variable gap between adjacent roofing panels on a doubly curved surface having positive gaussian curvature. The custom roofing panel


400


is adapted to bridge the variable gap between adjacent roofing panels on a doubly curved surface having negative gaussian curvature. The design and construction of such custom made roofing panels is expensive and time consuming. Persons of ordinary skill in the art will recognize that many other shapes and sizes of custom made roofing panels can be used to bridge such gaps.




Referring to

FIGS. 5 and 6

, another conventional approach to preventing gaps between cladding panels in the application of cladding panels onto doubly curved surfaces is to use an intermediate fixed member, often referred to as a clip, between the cladding panels to distort the cladding panels to thereby bridge the gap. As illustrated in

FIG. 5

, a conventional cladding


500


includes a first cladding panel


505


, a clip


510


, and a second cladding panel


515


.




The first cladding panel


505


includes a standing seam member


520


. The standing seam


520


includes a hook


525


. The second cladding panel


515


includes a standing seam member


530


. The standing seam member


530


includes a hook


535


. The clip


510


includes a standing seam member


540


and a base member


545


. The standing seam member


540


includes a hook


550


. The base member


545


of the clip


510


is mounted onto an underlying supporting structure (not illustrated).




The standing seam member


530


of the second cladding panel


515


overlaps and mates with the standing seam member


540


for the clip


510


. The standing seam member


540


for the clip


510


overlaps and mates with the standing seam member


520


for the first cladding panel


505


. The interaction of the hook


525


of the first cladding panel


505


with the hook


550


of the clip


510


prevents lateral movement of the hook


525


of the first cladding panel


505


relative to the hook


550


of the clip


510


. In similar fashion, the interaction of the hook


535


of the second cladding panel


515


with the hook


550


of the clip


510


prevents lateral movement of the hook


535


of the second cladding panel


515


relative to the hook


550


of the clip


510


.




When the conventional cladding


500


is mounted onto a doubly curved surface, the clip


510


is affixed to the underlying support structure


555


at a position proximate to the location where the gap would normally exist between the opposing edges


560


and


565


of the cladding panels


505


and


515


, respectively. The cladding panels


505


and


515


are then mounted onto the doubly curved surface using the standing seam member


540


of the clip


510


to distort the standing seam members


520


and


530


of the cladding panels


505


and


515


, respectively. In particular, the standing seam members


520


and


530


of the cladding panels


505


and


515


are displaced from a substantially vertical orientation by their overlapping and hooked relationship with the standing seam member


540


of the clip


510


. In this manner, the gap G between the opposing edges


560


and


565


of the cladding panels


505


and


515


is bridged by the displacement of the standing seam members


520


and


530


.




One limitation of the conventional approach to bridging the gap between adjacent cladding panels illustrated in

FIGS. 5 and 6

is the need to accommodate the vertical displacement of the standing seam members


520


and


530


of the cladding panels


505


and


515


. In particular, when the standing seam members


520


and


530


are displaced in a horizontal direction in order to bridge the gap G, the vertical height of the standing seam members


520


and


530


are reduced.




As illustrated in

FIGS. 7

,


8


and


9


, in a preferred embodiment, in order to accommodate the vertical displacement of the standing seam members


520


and


530


of the cladding panels


505


and


515


created by bridging the gap G, a supply of variable sized clips


700


,


800


, and


900


are provided at the construction site with various vertical heights H. In this manner, the optimum fit can be obtained in the interface between the cladding panels


505


and


515


and the clips. In an alternative preferred embodiment, a supply of clip


700


are provided at the construction site which can be modified to provide the clips


800


and


900


.

and/or the other cladding panels


1110


and

. In this manner, the bridging panel


1120
