где K1 - параметр, характеризующий кривизну конструктивного элемента крепи и вид напряженно - деформированного состояния спецпрофиля, принимающий значения: K1 = 6,93 - для прямолинейных элементов крепи при работе в упругой стадии; K1 = 5,66 - то же, при работе за пределом упругости; K1 = 2,91 - для криволинейных элементов крепи при работе в упругой стадии; K1 = 2,36 - то же, при работе за пределом упругости; W - параметр, принимающий значения упругого Wx или пластического Wт моментов сопротивления поперечного сечения спецпрофиля в зависимости от вида напряженно - деформированного состояния спецпрофиля; K2, K3, K4 и K5 - параметры, характеризующие форму и размеры поперечного сечения спецпрофиля.The invention relates to shaft metallic supports, to special interchangeable profiles. To ensure equal strength of the special profile in terms of strength and local stability, the thickness of its inclined walls d 1 and d of the bottom d are taken from the ratios:
where K 1 is a parameter characterizing the curvature of the structural element of the lining and the type of stress-strain state of the special profile, taking the values: K 1 = 6.93 - for rectilinear lining elements when working in the elastic stage; K 1 = 5.66 - the same, when working beyond the elastic limit; K 1 = 2.91 - for curvilinear lining elements when working in the elastic stage; K 1 = 2.36 - the same, when working beyond the elastic limit; W is a parameter that takes on the values of elastic W x or plastic W t of moments of resistance of the cross section of the special profile, depending on the type of stress - strain state of the special profile; K 2 , K 3 , K 4 and K 5 are parameters characterizing the shape and dimensions of the cross section of the special profile.
