Features of the creation of a reinforced frame

How to make a reinforced frame correctly

The bent rods should overlap the length of the entire site, and the angle of their inclination A is taken equal to 45 ° to the longitudinal axis of the element.

In beams with a height of more than 80 cm, it is allowed to take an angle of 60 °; In low beams and plates, you can take it for 30 °.

Adding a binder to glass -shaped material, on the one hand, increases the viscosity of the melt, and on the other, it reduces the effective coefficient of thermal conductivity. Both of these factors, ceteris paribus, should lead to an increase in the fraction of the gasified substance in the general prison of the mass or to a decrease in the role of the molten film.
