Reinforced Concrete Hidden Slab Beam Steel Column Concealed Support
This is a CAD dwg drawing detail for a Reinforced Concrete Hidden Slab Beam Steel Column Concealed Support. Concrete flat slab with a hidden beam reinforcement, is supported directly on top of a steel column ( HEB steel profile ) with a concealed ( hidden ) connection type.
Useful for architecturaly aesthetic reasons and when there is no false ceiling ( or minimum depth ceiling finish ) to hide the connection plate and bolts. These have to be concealed into the hybrid structure slab itself.
Hidden beam acts both as a punching shear reinforcement as well as a transverse beam to distribute horizontal loads into the slab.
Connection is made with a column top plate and full threaded anchor bolts embedded into the concrete slab ( prior to casting ). Small anchorage plates for better steel-concrete cohesion are illustrated on each anchor bolt inside the slab. Steel reinforcement detailing to accomodate all elements into the joint.
