         4 . The composite material polyurethane rigid foam decoration Roman column, as recited in  claim 3 , wherein said inner surface of said column basis part and said column cap part are respectively rough for increasing a friction to improve said firm combination between said inner layer and said column basis part and said column cap part respectively. 
     
     
         5 . The composite material polyurethane rigid foam decoration Roman column, as recited in  claim 1 , wherein a thickness of said column shell is 1-3 mm. 
     
     
         6 . The composite material polyurethane rigid foam decoration Roman column, as recited in  claim 1 , wherein a raw material of said column shell comprises a cross-linking agent. 
     
     
         7 . The composite material polyurethane rigid foam decoration Roman column, as recited in  claim 6 , wherein a content of said cross-linking agent is 5%40%. 
     
     
         8 . A method of manufacturing a composite material polyurethane rigid foam decoration Roman column, comprising following steps of:
 a) providing a column shell, and   b) closely jointing an inner layer on said inner surface of said column shell, having a material of PU, so as to be combined with said column shell to form a composite material to strengthen a support strength and a resistance of said column shell.   
     
     
         9 . The method of manufacturing a composite material polyurethane rigid foam decoration Roman column, as recited in  claim 8 , wherein said step b) comprises painting a PU glue on the surface of said column shell and said inner layer to strengthen a combination of said column shell and said inner layer without impacting a hardness and a density of said composite material polyurethane rigid foam decoration Roman column, comprising a component A and a component B, wherein said component A comprises polyether (hydroxyl value: 800-850): 40 parts, graft polyether (hydroxyl value: 400-450): 60 parts, cross-linking agent: 3 parts, organic tin catalyst: 0.5 parts, surfactant: 1; and said component B comprises isocyanate: 95-105 parts. 
     
     
         10 . The method of manufacturing a composite material polyurethane rigid foam decoration Roman column, as recited in  claim 8 , wherein said step a) comprises providing a T-shaped strengthening bones structure to increase a support strength of said column basis part and said column cap part, comprising a first board, having two sides provided on an inner surface of said column basis part and said column cap part respectively, and a second board provided vertically to said first board, having a first side provided on a center line of said first board, a second side provided on an inner surface of said column basis part and said column cap part respectively; and a plurality of stiffeners provided on said inner surface of said column basis part and said column cap part respectively in a direction parallel to said column body part for increasing said support strength of said column basis part and said column cap part respectively, and said inner layer is cross-linked with said column basis part and said column cap part respectively through increasing a contact area to improve an integration and a combination between said inner layer and said column basis part and said column cap part respectively.
