Structural laminated fiber-reinforced cement beams and columns

Abstract

A structural member for building fabrication, includes at least two layers of structural cement panels fastened together to have a common, aligned length and a common, aligned width. A building frame is provided, including a plurality of columns each having a lower end and an upper end, a plurality of beams each secured to at least one of the columns, each of the columns and beams is made of a plurality of layers of structural cement panels fastened together to have a common, aligned length and a common, aligned width.

1 . A structural member for building fabrication, comprising:
 at least two layers of structural cement panels fastened together to have a common, aligned length and a common, aligned width.   
     
     
         2 . The structural member of  claim 1 , including at least three layers of structural cement panels fastened together. 
     
     
         3 . The structural member of  claim 1 , wherein said layers are fastened together using chemical adhesive. 
     
     
         4 . The structural member of  claim 1 , wherein said layers are fastened together with threaded fasteners. 
     
     
         5 . The structural member of  claim 1 , further including at least one layer of steel located between adjacent layers of said at least two layers of structural cement panel and fastened to said adjacent layers. 
     
     
         6 . The structural member of  claim 1 , wherein members of said at least two layers are provided in varying lengths secured together in lengthwise staggered fashion to provide a member with a length greater than eight feet long. 
     
     
         7 . The structural member of  claim 1 , wherein members of said at least two layers have extensions extending beyond an end of the member for securing to adjacent members in a tongue and groove arrangement. 
     
     
         8 . The structural member of  claim 1 , further including gaps in said member created by using panels of varying lengths. 
     
     
         9 . A building frame, comprising:
 a plurality of columns each having a lower end and an upper end;   a plurality of beams each secured to at least one of said columns;   each of said columns and beams made of a plurality of layers of structural cement panels fastened together to have a common, aligned length and a common, aligned width.   
     
     
         10 . The building frame of  claim 9 , wherein said beams are configured so that each said panel is oriented so that a width of said panel projects vertically. 
     
     
         11 . The building frame of  claim 9 , wherein at least one of said columns, and at least one of said beams are configured by at least four layers of structural cement panels fastened together. 
     
     
         12 . The building frame of  claim 9 , wherein said layers of said columns and beams are fastened together using chemical adhesive. 
     
     
         13 . The building frame of  claim 9 , wherein said layers are fastened together with threaded fasteners. 
     
     
         14 . The building frame of  claim 9 , further including in at least one of said columns and at least one of said beams, a layer of steel located between adjacent layers of said at least two layers of structural cement panel and fastened to said adjacent layers. 
     
     
         15 . The building frame of  claim 9 , wherein members of said at least two layers are provided in varying lengths secured together in lengthwise staggered fashion to provide a member with a length greater than eight feet long.
