FIELD: municipal engineering, particularly to industrialize refuse chute structures.
SUBSTANCE: refuse chute comprises metal inner case formed of a number of stacked shells with funnel-shaped ends, inlet pipe, fire-resistance and soundproof outer facing. Each shell is composite. Upper shell comprises flange rested upon intermediate floor structure through antivibration pad and support frame. Shells are assembled by mutual connecting funnel-shaped ends provided with tension bands having packing members, wherein shells are arranged so that upper shell may be displaced relative lower one. Connection pipe is made as a single whole with lower shell.
EFFECT: simplified assemblage and improved service performance.
