Joints Between Precast Concrete Elements

Abstract

A joint between two adjacent faces ( 14 ) of concrete elements is formed by overlapping headed bar ( 16 ) with transverse studs ( 22 ) between the bars.

1 . A longitudinal joint between two precast concrete elements each having headed bars projecting from adjoining faces of the elements to be joined; the elements being positioned so that their respective headed bars are interleaved and overlap but are not in contact with one another; and headed studs positioned transversely to a length of the joint and transversely to and between the headed bars, the bars and studs being enclosed in concrete. 
     
     
         2 . A joint as claimed in  claim 1 , wherein the headed studs are double headed studs supported on a rail which rests on the overlapped headed bars. 
     
     
         3 . A joint as claimed in  claim 1 , wherein the headed studs are welded to a beam beneath the joint. 
     
     
         4 . A joint as claimed in  claim 1  wherein each element edge has a double row of headed bars. 
     
     
         5 . A joint as claimed in  claim 1 , wherein at least one longitudinal bar is positioned along the length of the joint. 
     
     
         6 . A joint between two precast concrete elements substantially as herein described with reference to the accompanying drawings.
