Abstract

A prefabricatd three-sided corner for dry wall and plaster construction possesses the shape of the interior of a trigonal pyramid with orthogonal sides from which triangular shaped panels are missing. The prefabricated corner preferably is made of high impact polystyrene with a semi-smooth surface, and has a thickness of 0.025 inches.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A prefabricated three-sided corner for dry wall and plaster construction in the shape of the interior of a trigonal pyramid with orthogonal sides.  
     
     
         2 . A prefabricated three-sided corner for dry wall and plaster construction in the shape of the interior of a trigonal pyramid with orthogonal sides from which triangular panels are missing.  
     
     
         3 . A prefabricated three-sided corner for dry wall and plaster construction essentially in the shape of the interior of a trigonal pyramid with orthogonal sides from which triangular panels are missing, but where the three resulting orthogonal arms of the resulting corner are squared off instead of pointed.  
     
     
         4 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 1  wherein the prefabricated corner is made of a rigid plastic material with a semi-smooth surface.  
     
     
         5 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 2  wherein the prefabricated corner is made of a rigid plastic material with a semi-smooth surface.  
     
     
         6 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 3  wherein the prefabricated corner is made of a rigid plastic material with a semi-smooth surface.  
     
     
         7 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 4  wherein the rigid plastic material is high impact polystyrene.  
     
     
         8 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 5  wherein the rigid plastic material is high impact polystyrene.  
     
     
         9 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 6  wherein the rigid plastic material is high impact polystyrene.  
     
     
         10 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 1  wherein the thickness of the prefabricated corner is 0.025 inches.  
     
     
         11 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 2  wherein the thickness of the prefabricated corner is 0.025 inches.  
     
     
         12 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 3  wherein the thickness of the prefabricated corner is 0.025 inches.  
     
     
         13 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 4  wherein the thickness of the prefabricated corner is 0.025 inches.  
     
     
         14 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 5  wherein the thickness of the prefabricated corner is 0.025 inches.  
     
     
         15 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 6  wherein the thickness of the prefabricated corner is 0.025 inches.  
     
     
         16 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 7  wherein the thickness of the prefabricated corner is 0.025 inches.  
     
     
         17 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 8  wherein the thickness of the prefabricated corner is 0.025 inches.  
     
     
         18 . A prefabricated three-sided corner for dry wall and plaster construction as described in  claim 9  wherein the thickness of the prefabricated corner is 0.025 inches.
