Abstract
Abstract There is disclosed a system of joining precast panels having an increased-thickness portion at one end of each panel, bordered by a slot for receiving caulking or the like to replicate the actual caulked joint deposed at the opposite border of the increased thickness portion of each panel. The system preferably provides smooth, unbroken interior walls, even at corners, and may be used to panel lengths up to forty feet or more. The disclosure also discloses means for making the panels, including apparatus for making differently-colored corner-dividers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
A wall comprising: two upright panels butted end to end and having a seam of joint fitting caulking material applied between them on at least one exposed side of the wall; each panel being constituted from panel facing material and hardened panel backing composition and having at least the face thereof corresponding to said one exposed side of the wall provided with an integral piller-like projection of greater thickness than the remainder of the panel, disposed at one end of the panel and set-off from the remainder of said face by a groove running from top to bottom thereof; said groove being at least partly filled with the same joint filling caulking material as said seam.
Claim 2
Dependent Claim
116 words
A wall comprising: two upright panels butted end to end and having a seam of joint fitting caulking material applied between them on at least one exposed side of the wall; each panel being constituted from panel facing material and hardened panel backing composition and having at least the face thereof corresponding to said one exposed side of the wall provided with an integral piller-like projection of greater thickness than the remainder of the panel, disposed at one end of the panel and set-off from the remainder of said face by a groove running from top to bottom thereof; said groove being at least partly filled with the same joint filling caulking material as said seam.
Claim 3
Dependent Claim
46 words
The wall of claim 1, wherein the joint filling caulking material of said seam and said groove is so similarly constituted and environmentally exposed and said groove is so shaped and filled that said seam is closely simulated by the groove and the caulking material therein.
Claim 4
Dependent Claim
16 words
The wall of claim 1, wherein the two upright panels are aligned in a straight line.
Claim 5
Dependent Claim
58 words
The wall of claim 1, wherein the two upright panels are set at right angles to form a corner with abutment of the remainder of one panel set back from the width dimension of the piller-like projection of the other panel to replicate the extent of this projection on both legs of the 270* side of this corner.
Claim 6
Dependent Claim
50 words
The wall of claim 1 wherein the panel facing material presents a substantial visual contrast to the hardened panel backing composition and is provided on said one face of said remainder of the panels, the projection and opposite face of the panels exposing the hardened panel backing composition in view.
Claim 7
Dependent Claim
35 words
The wall of claim 5 wherein the panel facing material is constituted by an array of brick slabs partly set into the panel backing composition and having one face of the slabs exposed to view.
Claim 8
Dependent Claim
22 words
The wall of claim 5 wherein the panel facing material and the panel backing material are made of concrete of contrasting colors.
Claim 9
Dependent Claim
