Abstract

An all glass composite building panel suitable for use as an integral structural member in roofs, ceilings, walls, and floors. The panel is constructed of three layers of glass separated by integral raised walls fused to the adjacent glass layers to define three possible combinations of two enclosed spaces; two layers of contiguous individual vacuum cells; one layer of contiguous individual vacuum cells and one layer comprising a serpentine passageway for liquid flow therethrough, said serpentine passage containing a heat absorptive material; or two layers comprising individual serpentine passageways for liquid flow.

Claims

1. An all glass building panel having a first enclosed space layer and a second enclosed space layer wherein:

a. the portion of said all glass building panel containing said first enclosed space layer comprises contiguous evacuated cells being comprised of;

a first outer glass plate,

first external glass walls fused to said first outer glass plate, one edge of said first external glass walls being fused to the circumferal edge of said first outer glass plate, said first external glass walls forming the closed external boundaries of said first enclosed space layer,

first internal glass walls fused to said first outer glass plate, one edge of said first internal glass walls being fused to said first outer glass plate within the boundaries of said first external glass walls to define the internal structure of said first enclosed space layer, and

a middle glass plate fused along its circumferal edge to the edge of said first external glass walls opposite the edge of said first external glass walls fused to said first outer glass plate and fused to the edge of said first internal glass walls opposite the edge of said first internal glass walls fused to said first outer glass plate; and

,

b. the portion of said all glass building panel containing said second enclosed space layer comprises a serpentine path for liquid flow therethrough, said serpentine path having integral means for ingress and egress of liquid thereto and therefrom, said serpentine path having a membrane disposed therein for absorbing solar energy and transmitting said absorbed solar energy to the liquid disposed therein, said second enclosed space layer being comprised of;

second external glass walls fused to said middle glass plate, one edge of said second external glass walls being fused to the circumferal edge of said middle glass plate, said second external glass walls forming the closed external boundaries of said second enclosed space layer,

second internal glass walls fused to said middle glass plate, one edge of said second internal glass walls being fused to said middle glass plate within the boundaries of said second internal glass walls to define the internal structure of said second enclosed space layer, and

a second outer glass plate fused along its circumferal edge to the edge of said second external glass walls opposite the edge of said second external glass walls fused to said middle glass plate and fused to the edge of said second internal glass walls opposite the edge of said second internal glass walls fused to said middle glass plate.

2. An all glass building panel comprising a first layer of glass, a second layer of glass, and a third layer of glass wherein:

a. said first layer of glass, said second layer of glass, and said third layer of glass are substantially parallel to each other;

b. said second layer of glass is disposed between said first layer of glass and said third layer of glass;

c. said second layer of glass has first integral raised walls on one surface and second intergral raised walls on the opposite surface;

d. the top edge of said first integral raised walls of said second layer of glass is fused to the adjacent surface of said first layer of glass forming a first enclosed space between said first layer of glass and said second layer of glass, said first enclosed space being comprised of contiguous evacuated cells; and

,

e. the top edge of said second integral raised walls of said second layer of glass is fused to the adjacent surface of said third layer of glass forming a second enclosed space between said second layer of glass and said third layer of glass, said second enclosed space comprising a serpentine path for liquid flow therethrough, said serpentine path having integral means for ingress and egress of liquid thereto and therefrom, said serpentine path having a membrane disposed therein for absorbing solar energy and transmitting said absorbed solar energy to the liquid disposed therein.
