sill rails

111, 112 facing the

beams

121, 122, 123, 124, 125, 126, and the respective beams The ends of 121, 122, 123, 124, 125, 126 are respectively disposed on the load-bearing ribs 111a, 112a. The ends of the

respective beams

121, 122, 123, 124, 125, 126 are carried by the load-bearing ribs 111a, 112a, which arrangement further enhances the

beams

beams

121, 122, 123, 124, 125, 126. Here, a specific number of

beams
