Laminated wooden post for building structure

Abstract

In a post type building formed by a plurality of spaced posts along the side of the building, each post is formed from a plurality of plies formed by dimensional lumber pieces with each ply being formed by at least two lumber pieces arranged end to end at a butt joint. The two lumber pieces forming each butt joint are connected together by at least one first truss plate bridging the butt joint and contacting the wider faces of the pieces. The plies forming the post are also connected together by a plurality of second truss plates at the junctions and at spaced positions along the post with each second truss plate contacting the narrower faces of each of the pieces, where each of the first and second truss plates including a flat plate portion for lying flat against a face of the lumber piece and a plurality of punched projection portions lying at right angles to the plate portion and engaging into the lumber piece.

1 . A laminated wooden post comprising; 
 a plurality of plies formed by dimensional lumber pieces;    each lumber piece having a width between two narrower faces and a thickness between two wider faces;    the lumber pieces forming the plies being arranged with the wider faces in contact such that the width of the pieces is equal to a width of the post and the sum of the thicknesses of the pieces is equal to the thickness of the post;    each ply being formed by at least two lumber pieces arranged end to end at a butt joint;    the butt joints of at least two of the plies being longitudinally off-set;    the two lumber pieces forming each butt joint being connected together by at least one first truss plate bridging the butt joint and contacting the wider faces of the pieces;    the plies forming the post being connected together by a plurality of second truss plates at the butt joints, with each second truss plate contacting the narrower faces of each of the pieces;    each of the first and second truss plates including a flat plate portion for lying flat against a face of the lumber piece and a plurality of punched projection portions lying at right angles to the plate portion and engaging into the lumber piece.    
     
     
         2 . The post according to  claim 1  wherein end pieces of the lumber of the post are formed from treated lumber for engaging into the ground and other pieces are formed from non-treated lumber.  
     
     
         3 . The post according to  claim 1  wherein there are additional second truss plates intermediate the butt joints at spaced positions along the post.  
     
     
         4 . The post according to  claim 1  wherein the first truss plates are located on the faces of the pieces facing outwardly toward an outside surface of the post.  
     
     
         5 . The post according to  claim 1  wherein the second truss plates are longer in a width across the thickness of the post than they are in a direction longitudinal of the post.  
     
     
         6 . The post according to  claim 5  wherein the second truss plates are substantially equal in width to the thickness of the post.  
     
     
         7 . The post according to  claim 1  wherein the first truss plates are substantially equal in width to the width of the pieces.  
     
     
         8 . A building comprising: 
 a plurality of vertical posts arranged along sides of the building;    connecting stringers extending along the sides and interconnecting the posts;    and cladding connected to the stringers and/or the posts;    the posts being engaged into the ground such that a lower end is supported by the ground and an upper end extends upwardly from the ground to support the sides;    each of the posts comprising a laminated wooden post according to  claim 1.
