FIELD: construction, particularly arrangements in buildings for the disposal of refuse. ^ SUBSTANCE: refuse chute for multistory building comprises shaft with loading gates at each story and damping device, which reduces gravitational speed of solid refuse loaded in the chute. The damping device is installed along chute axis at intermediate building story and retained with support. The damping device is shaped as semi-loop smoothly bending from chute shaft axis. The semi-loop has diameter and flexure equal to shaft diameter. The semi-loop is formed of separate singly-type branches provided with flanges to connect sections with each other, refuse chute and support. ^ EFFECT: decreased gravitational speed of solid refuse and, as the result, decreased noise propagation over building and improved safety, as well as increased simplicity and reliability and reduced costs. ^ 3 cl, 9 dwg |
