Abstract

Sposób wykonywania zespolonych, żelbetowo-kompozytowych elementów słupowych według wynalazku, w którym to sposobie wykonuje się rozbieralne deskowanie systemowe albo umieszcza się na podłożu zewnętrzny metalowy zamknięty profil (4) bądź kompozytowy będący formą traconą, wewnątrz których umieszcza się co najmniej jeden element zbrojeniowy słupa (3), który łączy się trwale z fundamentem, następnie zbrojenie (2), w szczególności w postaci żebrowanych prętów stalowych lub żebrowanych prętów kompozytowych, umieszcza się wewnątrz deskowania albo metalowego zamkniętego profilu (4) bądź kompozytowego, który to szkielet łączy się trwale z fundamentem, w kolejnym etapie konstrukcję wypełnia się mieszanką betonową, charakteryzuje się tym, że element zbrojeniowy słupa (3) stanowi profil perforowany otworami przelotowymi (1) 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 lub nie przekracza 0,3 średnicy bądź minimalnego wymiaru zewnętrznego profilu perforowanego nieobejmującego grubości profilu, przy czym minimalny rozstaw otworów przelotowych (1) wynosi co najmniej 2,5 krotność zastosowanej średnicy otworu przelotowego (1), natomiast całkowita powierzchnia perforowania zawiera się w przedziale od 0,1% do 30% całkowitej powierzchni profilu.A method of making composite reinforced concrete-composite column elements according to the invention, in which a detachable system formwork is made or an external metal closed profile (4) or composite profile being a lost form is placed on the substrate, inside which at least one reinforcing element of the column (3) is placed, which is permanently connected to the foundation, then reinforcement (2), in particular in the form of ribbed steel bars or ribbed composite bars, is placed inside the formwork or a metal closed profile (4) or composite profile, which skeleton is permanently connected to the foundation, in the next stage the structure is filled with a concrete mix, characterized in that the reinforcing element of the column (3) is a profile perforated with through holes (1) 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 or does not exceed 0.3 of the diameter or the minimum external dimension of the perforated profile not including the profile thickness, wherein the minimum spacing of the through holes (1) is at least 2.5 times the diameter of the through hole (1) used, while the total perforation area is in the range from 0.1% to 30% of the total profile area.
