Building Construction Handbook, Eighth Edition

System ~ comprises quality controlled factory produced

components of plain reinforced concrete walls and prestressed

concrete hollow or solid core plank floors.

Site Assembly ~ components are crane lifted and stacked manually

with the floor panel edges bearing on surrounding walls. Temporary

support will be necessary until the units are ``stitched'' together

with horizontal and vertical steel reinforcing ties located through

reinforcement loops projecting from adjacent panels. In-situ

concrete completes the structural connection to provide full

transfer of all forces and loads through the joint. Precast

concrete stair flights and landings are located and connected to

support panels by steel angle bracketing and in-situ concrete

joints.
