FIELD: construction.

SUBSTANCE: supporting parts of building structures for transferring the load from the beams of the superstructure to the underlying structures or supports. The supporting part is made in the form of a bar, which is made of a polymer concrete composition consisting of epoxy resin - 15%, PEPA hardener - polyethylenepolyamine - 0.5%, fine aggregate consisting of sand fraction 0.1-0.5 mm, cement and glass dust - 84.5%. Inside the polymer concrete bar, fibreglass reinforcement is laid in the areas of possible chipping of the material.
