A multichannel element comprises a longitudinal hollow body with rectangular or square cross-section, whose inner hollow is divided by at least one intermediate wall, strengthening rings are directed transverse. Herein, on the body edges adapter sleeves are performed for connection with bodies of adjacent multi-channel elements. The adapter sleeve made on one side of the body for connection to the body of adjacent multi-channel element is made as an enclosing recess; the adapter sleeve made on the other side of body for connection to the body of adjacent element is made as an enclosing flange. |
