Patent

CA 2493141

A load supporting structure such as a bridge deck is mounted on two spaced beams and includes a pre-cast concrete panel with a plurality of transverse tension straps attached to the edges of the panel by anchoring studs attached to the tension member and embedded within the panel such the tension straps- prevent spreading of the panel so that loads are transferred from an upper surface of the panel to the beams by forming a compressive arch within the panel. A concrete deck slab is cast over the pre-cast panel and is attached to the tension straps by embedded anchor studs located on the straps outside the panel so as to form a compressive arch within the slab. The compressive arch loading avoids the use of tension reinforcing steel in the concrete which can corrode. The use of a pre- cast panel and cast slab simplifies assembly as no welding to the beams on site is required.
