FIELD: construction industry.
SUBSTANCE: invention refers to construction industry, and namely to design of trash chute sections ensuring removal of domestic waste from buildings, but can also be used as section of assembled ventilation shaft of the building or construction. Trash chute section is made in the form of pipe with connecting broadening on one end from fibre-glass laminate consisting of several layers of glass-cloth or/and glass mat and hard-combustible bonding agent applied between glass-cloth layers. Between internal and external tube layers made in the form of shells there installed is zigzag-shaped corrugated filler contacting and connected with its protrusions to the above layers due to the bonding agent applied to glass-cloth and forming together with internal and external tube layers the through zigzag-shaped channels.
EFFECT: increasing strength of structure at simultaneous decrease of its weight, and as well as increase of thermal insulating properties of trash chute section and its durability owing to condensate moisture being discharged.
