Decking system

Abstract

Abstract The slab module disclosed herein consists of a precast prestressed slab section which may have solid or a hollow core. The slab module has a longitudinal male inserting edge which when installed mates with a complimentary-shaped female receiving edge on a similar slab module. However, the dimensions of the female edge are slightly greater than the corresponding male edges. The bottom surface of both male and female members are inclined at an angle to the plane of a side of the slab module so that the inserted module will move upward in translation as well as move toward the module into which its edge is being inserted. When the top or bottom surface (as desired) of the inserting module is at the same plane as the corresponding surface of the inserted module, a positioning spacer may be inserted to limit further movement and to maintain the relative position of the modules. The spacers may be in the form of plates which will vary in thickness. The joints between slab modules will be grouted after the slab modules are assembled. The modules will be drawn together by tendons. After assembly and adjustment of the slab modules, the tendons are post-tensioned and permanently anchored. The finished deck will appear and function as a smooth, continuous slab.
