FIELD: refuse disposal means, particularly refuse chutes for multistory buildings used for directional refuse movement to refuse collection and removal area.
SUBSTANCE: refuse chute section includes inner and outer metal shells and binding material filler located in-between. Binding material provides stiffening core of refuse chute section. Inner shell has longitudinal extension arranged on outer surface thereof. Outer shell is provided with spiral extensions formed on inner surface thereof. Above extensions extend in stiffening core and rigidly connected with it. Inner shell has projected edge located in lower part thereof and made so that lower end of inner shell is below lower ends of stiffening core and outer shell. Upper section end has bell part for receiving identical section to be connected with it. Formed under bell part are mounting orifices located from opposite sides of upper section end.
EFFECT: increased strength, reduced material consumption and labor inputs for refuse chute assemblage, enhanced ecology.
