Definitions
- the invention relates to a reinforcing or connecting element, preferably made of steel, for locally reinforcing the reinforced concrete parts at a point of connection with other components.
- the invention has for its object to provide an improvement especially in this regard.
- the invention lies in at least one longitudinal and one transverse plate for generating frictional forces caused by the internal forces of the interconnected components on the surfaces, in particular of the transverse plate.
- This creates a spatial reinforcement or connecting element that can be welded together, for example, from steel sheets of 10 to 80 mm thick and other steel profiles, and in the case of the shape and location of these parts the internal forces of the components to be joined together in an advantageous manner.
- the execution technology can be simplified, the costs can be reduced.
- a reinforcement element designated as a whole by 10 (FIGS. 1 to 3) consists of, for example, 20 cm high and 2 cm thick longitudinal sheets 1, which have a 20 cm high and 3 cm thick cross plate 2 are connected.
- An I-profile for example a crossbar 3 having INP 18, is welded in between longitudinal sheets 1 which are provided with holes 4.
- the reinforcing element 10 is in place.
- 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 are concreted in.
- 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 pressing forces and thus friction 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, e.g. 16 cm high and 2 cm thick flat steels 12. In the middle are e.g. 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.
- Element 33 is on the ver binding site 34 concreted.
- a connection 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 reinforcing element 33, since a displacement between the concrete of the parts 15, 16 and the reinforcing element 33 is impossible.
- cross plates 19 a three-part, 40 cm high and 4 cm thick longitudinal plate 20 welded.
- U-profiles 21, each consisting of two angle irons, are welded to the free ends of the sheets 19, 20, 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.
- the point 36 of a connection between a foundation or base plate 22 and a steel support 23 clamped therein is shown.
- 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 lateral forces K, L are generated in the foundation plate.
- the bending moments P, Q create frictional forces on the smooth surfaces 19a, 21a, which are designed without special ribs or the like, whereby the transmission of the force J exerted by the support 23 and the moment N to the foundation plate 22 is ensured.
