Increasing the thermomechanical properties of sheet glasses for the purpose of creation of fire-resistant light-transparent enclosures of high buildings
Keywords:fire safety, translucent structures, fire resistance, heat resistance, chemical hardening
Purpose. Investigation of the thermomechanical properties of sheet glass used for translucent enclosing structures with the development of measures to increase the level of fire safety of high-rise buildings.
Methods. To solve the set tasks, theoretical and experimental research methods are used. The theoretical method is based on solving the problems of the thermal regime of solids and analyzing the criteria for the destruction of translucent structures in a fire. The experimental method is based on the identification of the relationship between the parameters of the fire and the criteria for the destruction of the translucent facade on the fire floor and upper lying floors.
Findings. The review of the state of the problem in the field of fire safety of high-rise buildings with facade glazing is carried out. It is established that the currently used translucent enclosing structures are made mainly of multilayer or tempered glass, which causes an increased load on the foundation, high cost and does not always preserve the integrity of the structure in the event of a fire. Experimental studies of the hardening of sheet glass of different denominations by chemical quenching were carried out, the possibility of using this method to create fireproof glasses was evaluated.
Application field of research. Fire safety in construction, translucent building envelopes.
