Composite steel floor structure

Abstract

The composite steel ceiling consists of two thin-walled channel sections (1) arranged in a mirror image of each other, connected by connectors (2) mounted in the vertical holes of the fourth shelves (10) of the channels, where the channels have a shape similar to the letter C with four shelves, where the first shelf (7) and the third shelf (9) are parallel to each other, and the first shelf (7) has a length not greater than 1 / 2 of the height of the second shelf (8) and is directed towards the inside of the ceiling.The second shelf (8) is perpendicular to the first shelf (7) and the third shelf (9), and the fourth shelf (10) is perpendicular to the third shelf (9) of the channel section and directed towards the interior of the ceiling, wherein the space between the Z-sections is filled with concrete (6) simultaneously with concreting the floor slab, and in the upper part of the second shelves (8) of the channel section (1) there are side holes in which a screw (3) is mounted parallel to the third shelf (9) of the channel section (1), wherein in the space between the upper edge of the vertical fourth shelves (10) and the screw (3) there are two reinforcing bars (13) parallel to the longitudinal axis of the channel section (1).
