Abstract

Element zbrojeniowy elementów słupowych stanowiący profil wewnętrzny o przekroju zamkniętym charakteryzuje się tym, że profil (1) jest perforowany otworami przelotowymi (2) o jednakowej średnicy, która to średnica wynosi od 3 do 5 krotności średnicy maksymalnego wymiaru ziarna kruszywa zastosowanego w mieszance betonowej lub od 2 do 5 krotności długości włókna zastosowanego w mieszance betonowej oraz nie przekracza 0,3 średnicy bądź minimalnego wymiaru zewnętrznego profilu perforowanego nieobejmującego grubości profilu. Przy czym minimalny rozstaw otworów (2) wynosi co najmniej 2,5 krotność zastosowanej średnicy otworu, natomiast całkowita powierzchnia perforowania zawiera się w przedziale od 0,1% do 30% całkowitej powierzchni profilu.The reinforcing element of column elements constituting an internal profile with a closed cross-section is characterized in that the profile (1) is perforated with through holes (2) of the same diameter, which diameter is from 3 to 5 times the diameter of the maximum size of the aggregate grain used in the concrete mix or from 2 to 5 times the length of the fiber used in the concrete mix and does not exceed 0.3 of the diameter or the minimum external dimension of the perforated profile not including the thickness of the profile. Wherein the minimum spacing of holes (2) is at least 2.5 times the diameter of the hole used, while the total perforation area is in the range from 0.1% to 30% of the total area of the profile.
