Розробка та випробування металевих конструкцій для спасіння людей з висоти

Abstract

The possibility of equipping high-rise residential buildings with emergency rescue systems -portable overhead cable winches is considered. The use of such devices allows you to increase the number of escape routes from the building and reduce the time of evacuation of residents from the emergency zone. Metal roof structures were developed for fixing winches. Structures are metal consoles mounted on the roof of residential buildings, attached to existing reinforced concrete bearing structures. In situ tests of metal structures for fire purposes were performed. Tests have shown that such structures withstand static and dynamic loads without damage and loss of stability. At the control load on checking the boundary of the structure strength with a load P = 10 kN applied to two loops, the absence of tearing out the anchoring mounts of the structure to reinforced concrete slabs of the coating and breaking the loops was revealed.
