Definitions
- the invention relates to a connection of a reinforced concrete component with at least one other component, with a reinforcing element, preferably made of steel, which is embedded in the concrete of the reinforced concrete component at the point of connection.
- the invention has for its object to provide an improvement especially in this regard.
- the invention consists in that the reinforcement element is formed at least from a first sheet with a rectangular cross-section, smooth, compound-free surfaces, which is connected over its cross-sectional height to at least one smooth, compound-free surfaces transverse cross-section corresponding to its longitudinal direction, corresponding rectangular cross-sectional height, and that the reinforcing element is arranged such that contact forces and thus frictional forces are generated by internal pressure forces at the connection point, in particular on the smooth surfaces of the cross plate, which serve to establish the balance of the forces at the connection point.
- Compound-free is to be understood to mean that there are no bolts, side screws, etc., and also no flanges on the sheet metal, through which the force transmission could take place.
- a reinforcement element designated as a whole by 10 (Fig. 1 -3) consists of z. B. 20 cm high and 2 cm thick longitudinal sheets 1, which are connected to a 20 cm high and 3 cm thick cross plate 2. Between longitudinal sheets 1 is an I-profile, for. B. INP 18 having crossbar 3 welded.
- the reinforcement element 10 is concreted into the location 32 of the connection of a pressure belt 7, a truss post 6 and a tension diagonal 8 screwed to the web 3 by means of screws 31.
- the compressive forces D directed towards the connection point 32 are assumed, in the truss post 6 the axial force E and in the tension diagonal 8 the tensile force F directed away from the connection point 32.
- the compressive forces D in the belt 7 generate 2 contact forces on the smooth surfaces (friction surfaces) 2a of the transverse plate, which are without ribs or the like.
- the frictional forces serve to establish the equilibrium of the forces D, E, F at the connection point 32.
- the reinforcement or connecting element 33 consists of two transversely arranged, for. B. 16 cm high and 2 cm thick flat steels 12. In the middle of z. B. 16 cm high and 2 cm thick longitudinal flat steel 13 welded. U-profiles 14 are welded to the free ends of the flat steels 12, 13. Together with the transverse plates 12 and the longitudinal plates 13, they form a closed, rectangular frame.
- the element 33 is suitable for the transmission of moments.
- FIG 8 shows a point 34 of the connection of a horizontal plate strip (ceiling or floor) 15 to a wall 16, both of which are made of reinforced concrete.
- the element 33 is concreted in at the connection point 34.
- a connecting torque M caused by the plate strip 15 generates frictional forces on the pressure surfaces 12a of the transverse plates 12.
- the force pair G, H equivalent to the moment M can therefore be introduced into the wall 16.
- the transmission of the moment M is improved by the closed shape of the reinforcement element 33, since a displacement between the concrete of the parts 15, 16 and the reinforcement element 33 is impossible
- FIGS. To 11 is on two z. B. 40 cm high and 3.5 cm thick transverse sheets 19 a three-part, 40 cm high and 4 cm thick longitudinal sheet 20 welded. At the free ends of the sheets 19, four four U-profiles 21 each consisting of two angle irons are welded on, so that an element 35 with a closed frame is formed. The element 35 is suitable for the simultaneous transmission of axial forces and moments.
- FIG. 12 shows the location 36 of a connection between a foundation or floor slab 22 and a steel support 23 clamped therein.
- the reinforcing element 35 is concreted into the foundation plate 22 made of reinforced concrete and connected to the steel support 23 by means of weld seams 37.
- the normal force (weight force) of the support 23 is J and the support is subjected to a moment N. Then 22 bending moments P, Q and transverse forces K, L are generated in the foundation plate.
- the bending moments P, Q result on the smooth, without special ribs or the like. executed surfaces 19a, 21a frictional forces, whereby the transmissions of the force exerted by the support 23 and the moment N to the foundation plate 22 is secured.
