<p>A parking garage having pre-cast portions has an external support wall surrounding an intermediate support wall which terminates short of the external wall. The intermediate support wall separates a number of ascending bays formed of slabs supported by the two walls. At each end of each bay a plurality of dihedral sections are positioned, each dihedral ection having a horizontal portion and an inclined portion. The free end of each horizontal portion rests on the external wall and the free end of each inclined portion is carried on a beam which spans the distance between the intermediate wall and the external wall. The horizontal portions form an extension to the bay for turning purposes and the inclined portions form a ramp leading from the bay.</p> |
