Column Shoe Manufactured From One Piece of Sheet Metal

Abstract

The present invention relates to a bent column shoe formed from one piece of sheet metal with a material thickness, the sheet metal having a first side and a second side, the bent column shoe comprising an anchor section with a longitudinal axis and a width axis, wherein the anchor section has a first end and a second end, —a supporting section with a first supporting end and a second supporting end, wherein the first supporting end is in extension of the second end of the anchor section, a support section with a support face, arranged substantially perpendicular to the longitudinal axis of the anchor section, and wherein the support section is arranged in extension of the supporting section, and at least one fastening face arranged substantially perpendicular to the support face, and wherein the anchor section, the supporting section, the support section and the at least one fastening face are manufactured from one and the same piece of sheet metal, characterised in that the anchor section, measured along the width axis, comprises at least three layers of the sheet metal arranged to provide at least three times the material thickness relative to the support section measured along the longitudinal axis.

1 . A bent column shoe formed from one piece of sheet metal with a material thickness (wt), the sheet metal having a first side and a second side , the bent column shoe comprising:
 an anchor section with a longitudinal axis and a width axis, wherein the anchor section has a first end and a second end,   a supporting section with a first supporting end and a second supporting end, wherein the first supporting end is in extension of the second end of the anchor section,   a support section with a support face, arranged substantially perpendicular to the longitudinal axis of the anchor section, and wherein the support section is arranged in extension of the supporting section, and   at least one fastening face arranged substantially perpendicular to the support face, and wherein the anchor section, the supporting section, the support section and the at least one fastening face are manufactured from one and the same piece of sheet metal,   characterised in that the anchor section, measured along the width axis, comprises at least three layers of the sheet metal arranged to provide at least three times the material thickness (wt) relative to the support section measured along the longitudinal axis.   
     
     
         2 . A bent column shoe formed from one piece of sheet metal according to  claim 1 , wherein the at least three layers are substantially parallel. 
     
     
         3 . A bent column shoe formed from one piece of sheet metal according to  claim 1  or  2 , wherein anchor sections comprise three 180° bends and four substantially parallel flat areas. 
     
     
         4 . A bent column shoe formed from one piece of sheet metal according to  claim 1 ,  2  or  3 , wherein the supporting section comprises a supporting end part, the end face of which comprises a support edge at substantially the same level as the support face of the support section. 
     
     
         5 . A bent column shoe formed from one piece of sheet metal according to any of  claims 1 - 4 , wherein the second supporting end of the supporting section has a width which is wider than the first supporting end. 
     
     
         6 . A bent column shoe manufactured from one piece of sheet metal according to  claim 5 , wherein the supporting section expands evenly in width from the first support end towards the second supporting end. 
     
     
         7 . A bent column shoe formed from one piece of sheet metal according to any of  claims 1 - 6 , wherein the side faces of the anchor section comprise recesses, and/or wherein the bent areas of the anchor sections comprise recesses. 
     
     
         8 . A bent column shoe formed from one piece of sheet metal according to any of  claims 1 - 7 , wherein the column shoe is manufactured from galvanised steel such as S 220 GD, S 250 GD, S 280 GD, S 320 GD or S 350 GD. 
     
     
         9 . A bent column shoe formed from one piece of sheet metal according to any of  claims 1 - 8 , wherein the material thickness of the initial plate metal is 1mm-5mm, or 1.5mm-4.5mm, or 2mm-4mm, or 2.5mm-3.5mm. 
     
     
         10 . A bent column shoe formed from one piece of sheet metal according to any of  claims 1 - 9 , wherein the fastening section(s) and/or the support section comprise a number of holes for fastening between the column shoe and the post to be mounted. 
     
     
         11 . A bent column shoe according to  claim 10  wherein the holes in the one fastening section are offset in relation to the holes in the other fastening section. 
     
     
         12 . A bent column shoe according to any of the preceding claims wherein a circular cross-sectional shadow area of the anchor section is 10mm-50mm, or 12.5mm-40mm or more preferred 15mm-30mm. 
     
     
         13 . A bent column shoe according to any of the preceding claims wherein the column shoe is manufactured from stainless steel. 
     
     
         14 . Method of manufacturing a column shoe according to any of the  claims 1 - 13  wherein the base material is a coil, and the column shoe is manufactured having the longitudinal axis of the anchor section arranged transversely to the longitudinal axis of the base material during the bending of the entire column shoe. 
     
     
         15 . Method of manufacturing a column shoe according to  claim 14  wherein the width of the support section can be changed without changing the transverse dimension of the base material.
