Demountable floor construction

Abstract

Demountable Floor Construction A floor plank ( 10 ) for use in a flooring system comprises a reinforced, inverted U-shaped, precast concrete element having an upper surface and depending ribs ( 14 ) along its longitudinal edges. The planks are supported on spaced horizontal beams ( 6 ) during assembly. The planks are interconnected by means of connector plates ( 52, 54, 56, 58 ) and bolts ( 50 ) along their edges to create a floor diaphragm and surface appropriate for use.

1 . A flooring system comprising planks each comprising a reinforced, inverted U-shaped, precast concrete element having an upper surface and depending ribs at longitudinal edges; wherein bolt sleeves for receiving removable bolts are preformed into the planks extending from the upper surface into the ribs of the plank; and connector plates carrying removable bolts for connecting adjacent planks to enable a full diaphragm floor to be created. 
     
     
         2 . A flooring system as claimed in  claim 1 , wherein recesses surrounding the bolt sleeves are preformed into the upper surface of the planks to receive the connecting plates. 
     
     
         3 . A flooring system as claimed in  claim 1 , wherein the bolts are assembled from a counter sunk head, a threaded stud and a sleeve coupler. 
     
     
         4 . A flooring system as claimed in  claim 1 , wherein joints between the planks are filled with a grout or concrete mix.
