A modular security vault structure having a plurality of prefabricated concrete panels forming the vault side, ceiling and floor walls. Some of the panels have integral corners. The panels are formed with tongues and grooves for tongue and groove joint connection between adjacent panels. Spaced rows or layers of reinforcing bar grids are embedded within the panels. The ends of the bar grids extend into the tongues and into the panels on either side of the grooves so as to overlap at each tongue and groove joint. Plates cover the joint lines between panels on the inner vault surfaces. The plates are bolted to sockets embedded within the panels and connected with the bar grids. Vertical panel joints in the vault side walls are offset from horizontal joints in the vault ceiling and floor walls. A usual vault door may be hung in a wall of the modular vault structure. Lighting, alarm and ventilating requirement conduits, offset at least once, may be embedded in the prefabricated panels so that any vault structure can be erected completely and quickly at the bank site.
