Effluents treatment shaft uses double bottom with reinforcing beam between parts plus bottom beam plate and end frames for load transfer to casing.

摘要

A separate reinforcing profile is installed in the space (5) between the top (2) and bottom (3) parts of the double bottom (2,3). The beam (4) plate (8) is adapted to top or bottom parts and bears on these via web pieces (9) as joined to the plate (8). The webs (9) are adjoined at one end by a frame (10) and are designed as I-rails. The frame (10) takes up any sagging of the bottom part (3) and plate (8) via the webs (9) and transmits these at the rims to the surround casing (1).
