Prefabricated section for constructing buildings - has partitions defining central cavity with grouting holes in sides and end tenons to fit loosely in mortices in adjacent similar section

摘要

The prefabricated section consists of two sides (2, 3) and crosswise partitions (4, 5) in the top of which are crosswise cutouts holes (6). The crosswise partitions separate central switches (7, 8, 9) and end wall (10, 11). The top of ends are of reduced thickness (12) and the sides around the central cavity (9) are similarly thinner. Grouting holes (13) surround the central cavity (8). At one end there are vertical tenons (14, 15) and at the one end, vertical mortices, (16, 17) which are circular in cross-section so when inserted in a mortice. There is a gap between tenon and mortice. One end (10) is shallow and the other end (11) extends the full height.
