SU1231171A1 - Steel-ferroconcrete construction element - Google Patents

Description

The invention relates to the construction and can be used as a ceiling for industrial and residential buildings.

The purpose of the invention is to increase the carrying capacity.

FIG. 1 shows the proposed element, the cut; in fig. 2 is a section A-A in FIG. 1 {fig, 3 - cutting scheme of the upper shelf of the flooring, isometry.

The element contains a metal beam 1, along which a steel profiled flooring 2, welded with rod anchors 3 to beam 1, is laid.

On flooring 2 monolithic concrete 4 slabs 5 was laid. Staff 5 has ribs 6. Within the upper shelf of flooring 7, cuts are made and made

limb 8 to beam 1 and limb 9, perpendicular to the longitudinal axis of the beam 1. In the limb 9 there are holes for riffs 10.

The bends 9 make it possible to concrete the cavity between the ribs 6 within the upper beam 1, and also facilitate the placement of anchors 3.

The compressive force arising in concrete 4 under the action of a positive bending moment on an element is perceived by a section with a height equal to the full height of plate 5 within the width of the beam flange.

The bends, made with holes 10, make it possible to use the effect of indirect formation to increase the strength of hardened concrete.

Claims (3)

1 BUILDING STEEL CONCRETE ELEMENT, including a metal beam and rigidly connected to it using reinforced concrete anchors. a plate with steel corrugated flooring in the lower zone, which can be explained by the fact that, in order to increase the bearing capacity, the upper shelf of the flooring at the places adjoining the beam is made with a hole formed by the notches bordered by pairwise symmetrical bends, and a couple of bends, oriented in a plane, perpendicular to the longitudinal axis of the beam, is directed upward, and a pair of limbs oriented in a plane parallel to the longitudinal axis of the beam is directed downward, with the cavity between the beam and the flooring in the places where the hole is made apolneny concrete. 2. The element. By π. 1, distinguished by the fact that the bends upward are perforated 3. An element by π. 1, due to the fact that the bends upward are made with reefs. ¹ 1231171
