Abstract


Purpose. Ensuring security reference emergency-recovery and repair-construction works for account modernization design monolithic panel glazing took employees special forces.

Methodology. Application special technical funds for software security specialized units at occurrence emergency situations.

Findings. In article considered questions increase security employees, performing emergency-recovery and repair-construction work in extreme conditions on objects construction industry. Authors offer design helmets with visor, protected patent of Ukraine and mathematically reasonable calculation model to it, which allow generalized step up to definition stress-strain state (SSS) multilayer protective took. Improved technique calculation on strength monolithic panel glazing took at collision with load, that agreed with methods of test helmets fire according to state standard. As initial stage advance (on stage design) calculations stresses and deformations, arising from pulse impact on outer cylindrical surface glazing took developed technique definitions values stresses in monolithic design panel glazing modern helmets fire-rescuer, made of polycarbonate.

Originality. For stress-strain state states standard monolith obtained typical linear depending on functions stresses, operating in fibers glazing from depths their location in glazing took at given foreign pulse load. Given specific calculation data. Comparison results calculation with main provisions theory elasticity about SSS plates and shells show about their correctness.

Practical value. Obtained findings with help which possible modernization helmets fire-rescuer and methods its constructive hardening, based on comprehensive analysis data problem adoption solutions in conditions certainty.


Keywords


Аccident recovery and repair construction works; safety of work; protective helmets and visor; curvature radius and thickness of monolithic glazing visor; the calculation of strength.
