Title: Edge reinforcement for sandwich-type building panel

Abstract: An edge reinforcement for a sandwich-type building panel comprises a sheet-metal reinforcing member which extends along the edge of the panel between the two outer plates thereof and is of laterally open box shape. This reinforcement member is formed with a groove adapted to receive a spline that connects together the two like panels. In addition, the reinforcement member is formed on a section extending transverse to the two plates with a plurality of holes so that synthetic resin may be injected through this reinforcement member into the space between the two plates which are separated and held apart by the reinforcement member. The member may comprise a pair of like profiles each lying against a respective outer plate and in turn embracing a single sound-deadening inner plate formed with a plurality of foam-passing holes.
