Abstract
Abstract A prefabricated panel and method for making same for use in the construction of a wall structure for a building. Each panel section is comprised of a rigid support structure for attachment to the building framework. A plurality of facia sheets, such as tiles, overlie the exterior surface of the support structure and are resiliently bonded thereto with a means which provides limited relative movement between the facia sheets and the supporting structure. A means for sealing the joints between adjacent edges of facia sheets on a single panel section is provided, and once the panels are installed on a building framework, means for sealing the joints between adjacent panels is also provided in order to form a contiguous weathertight wall surface.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
114 words
In a wall structure for a building having a plurality of prefabricated panel sections secured to the building framework to form a wall surface, each panel section comprising: a rigid support structure for attachment to the building framework including a structural frame and a formed metal deck secured to the frame, said deck having alternating ridges and grooves; a plurality of facia sheets overlying one side of said support structure, said sheets formed of material selected from the group consisting of ceramics and masonry; means for resiliently securing the facia sheets to the support structure for permitted limited relative movement therebetween; and means for sealing the joints between adjacent edges of the facia sheets.
Claim 2
Dependent Claim
114 words

Claim 3
Dependent Claim
45 words
The invention of claim 1 wherein the facia sheets overlie one surface of the deck; means between the ridges of the deck and the facia sheets for spacing the sheets from the deck; and resilient adhesive means for bonding said facia sheets to the deck.
Claim 4
Dependent Claim
38 words
The invention of claim 2 wherein the means for spacing the facia sheets from the deck comprises resilient strips secured to the deck beneath adjacent edges of facia sheets and cooperating with the means for sealing the joint.
Claim 5
Dependent Claim
41 words
The invention of claim 3 wherein said resilient spacing strip has an adherent side secured to the deck and a nonadherent side beneath said facia sheets and cooperating with the means for sealing the joints between edges of the facia sheets.
Claim 6
Dependent Claim
18 words
The invention of claim 2 wherein the resilient adhesive means for bonding comprises a silicon based structural adhesive.
Claim 7
Dependent Claim
17 words
