FIELD: construction. ^ SUBSTANCE: in a composite beam structure there is one or more parts in the form of boards and a beam are connected together by means of an ingot. The beam structure comprises a steel beam, above which there is one or more mounting pins. Length of mounting pins at least three times exceeds the width of the upper surface of mounting pins. The pin is arranged with the possibility to transfer a force in connection between concrete and steel in the vertical and longitudinal direction relative to the beam. In a transverse cut perpendicular to a longitudinal direction of the pin there is at least one part, in which the pin width is more than on a section arranged directly below. ^ EFFECT: high-quality combination of technical parameters of a beam. ^ 15 cl, 10 dwg |
