Definitions

  • the invention relates to a device for shear force connection of a first, in particular plate-shaped, component made of reinforced concrete with a second component, typically also made of concrete or reinforced concrete, with an elongate sleeve and with a shear force mandrel, the sleeve for embedding flush with the edge in the concrete of the first component, the shear force mandrel being able to be pushed into the sleeve from the outside, the sleeve being able to be inserted into a reinforcement element, the reinforcement element being formed with a plate arranged on an end face of the reinforcement cage, the plate having a recess through which the sleeve being penetrable provided that the portion of the sleeve which is passed through is placed inside the reinforcement cage and the recess of the plate has a cross-sectional area which is greater than the outer cross-sectional area of the sleeve.
  • the first component for example a plate-shaped component made of reinforced concrete
  • the second component can be a load-bearing component such as a stairwell wall.
  • two plate-shaped components made of reinforced concrete, such as two ceilings can also be connected to one another, for example as an expansion joint. It can also be a connection between a wall and a ceiling.
  • the invention also relates to a building with such a device, a use of such a device, and a set of components containing the components of this device.
  • Devices for shear force connection of the type mentioned are, for example, from the reference EP 3 023 555 B1 known and are used in particular for the support of, for example, plate-shaped first components, such as platforms or flights of stairs, in load-bearing second components such as a stairwell wall.
  • the transverse force caused by the weight of the first component is transmitted to the second component by the transverse force mandrel that is pushed into the sleeve with one end.
  • the transverse force mandrel is, for example, a square tube made of stainless steel. Under the effect of the shear force, the shear force mandrel presses against the top of the sleeve, which transfers the pressure to the concrete material.
  • a disadvantage of the known devices is that during assembly there is practically no room for slight twisting of the transverse force mandrel, for example if at least one of the components to be connected is slightly warped.
  • Other devices for shear force connection of a first component made of concrete with a second component are, for example, from the references EP 2 754 766 B1 , EP1 477620 B1 , EP 2 982 807 B1 , EP 3 339 525 B1 , EP 2 146 004 B1 , EP 2 516 761 B1 , DE 10 2005 036 8814 B4 , and EP 2 655 754 B1 famous.
  • the invention is therefore based on the technical problem of creating a device for connecting a first component made of concrete with a second component made of concrete, which allows simpler construction of structures made of at least two components, in particular if at least one of the components has a certain warpage .
  • the invention teaches the subject matter of claim 1.
  • the reinforcement element can be aligned independently of the position of the sleeve. This means that the sleeve and the reinforcement element can be pivoted or tilted freely relative to one another, without restoring forces forcing the sleeve back into a position that is axially parallel or coaxial with the reinforcement element.
  • the space between the sleeve and the reinforcement element is preferably empty (until it is filled with concrete) (in particular not filled with elastic and/or compressible solids) in order to enable the sleeve to pivot in the reinforcement element. This ability to be aligned or pivoted is important because in practice it can happen, for example, that the first component is somewhat warped.
  • Lateral force mandrels are then often installed in the area of such a distortion or such a misalignment, as they are intended to absorb lifting forces and prevent the first component from tipping.
  • the invention allows the reinforcement element to be tilted to a greater or lesser extent in relation to the sleeve, which considerably simplifies assembly.
  • the second component can be a concrete component, with the shear force mandrel being embedded in concrete.
  • the second component it is also possible for the second component to be designed in the form of an impact sound insulation box in the area of the shear force mandrel inserted into the second component, with this impact sound insulation box forming part of the second component.
  • the second component outside of such a footfall sound insulation box can consist of any statically suitable material, usually it will also be concrete, but typically not necessarily reinforced.
  • the second component can be a masonry wall, for example, in which such a footfall sound insulation box is aligned and installed using a layer of mortar
  • both the first and the second component each have a reinforcement element with an inserted sleeve, in which case the transverse force mandrel is then inserted with its opposite ends into a respective sleeve.
  • a reinforcement element with an inserted sleeve
  • the transverse force mandrel is then inserted with its opposite ends into a respective sleeve.
  • both plates of both reinforcement elements can be provided with recesses that are enlarged according to the invention be, but it is also possible that a recess of a plate has a cross-sectional area which corresponds almost exactly to the outer cross-sectional area of the sleeve.
  • a reinforcement cage can in principle be of any desired design, provided it has an elongated shape and a sleeve can be inserted from one of its end faces.
  • a reinforcement cage can have, for example, two U-shaped reinforcement rods which are arranged parallel to one another at a distance. This distance is larger, in particular at least 10%, 20%, 30%, 40%, or 50% larger, but also at least 60%, 70%, 80%, 90%, or 100% larger than the outer diameter a sleeve inserted therein.
  • the respective legs of the U-shaped reinforcing bars also have a distance that is greater, in particular by at least 10%, 20%, 30%, 40%, or 50% greater, but also by at least 60%, 70%, 80%, 90% %, or 100% larger, than the outside diameter of a sleeve mating therewith.
  • the two mutually parallel U-shaped reinforcing rods can be connected to one another by ring rods running around the four legs of the U-shaped reinforcing rods.
  • the plane of the ring bars can be orthogonal to the four legs of the U-shaped reinforcing bars, but it is also possible to bend the ring bars with respect to the orthogonal position.
  • the ring bars can be distributed evenly or unevenly over the length of the legs. 2 to 20, in particular 2 to 10, ring bars can be provided for a pair of reinforcing bars bent in a U-shape.
  • a reinforcement element is formed from the elongated reinforcement cage and one at one end of the reinforcement cage attached plate formed.
  • the plate is firmly or force-transmittingly connected to the reinforcement cage, cohesively (e.g. by welding or gluing) or by means of connecting elements such as screws, rivets or locking elements.
  • the plate is preferably flat and is orthogonal to the longitudinal extension of the reinforcement cage. However, it is also possible for the flat plate to be angled relative to a longitudinal axis of the reinforcement cage at an angle of less than 90° and greater than 45°, in particular greater than 60°, 70° or 80°.
  • the plate can also be bent, for example, in the form of a segment of a cylinder jacket surface (arc shape), have a bevel (pitched roof shape), or have a plurality of bevels parallel to one another.
  • This can be recommended, for example, for a reinforcement cage with reinforcement rods bent in a U-shape, in which case an adaptation to the shape of the “U” is possible.
  • the recess of the plate has a cross-sectional area which is so much larger than the outer cross-sectional area of the sleeve that the sleeve is at least 2°, 3°, or 4°, preferably at least 5°, 6°, relative to the plate °, 7°, 8°, 9° or 10°, in particular from 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, or 9° up to 10°, 15° , or 30°, measured between a longitudinal axis of the reinforcement cage and a central axis of the sleeve.
  • the recess in the panel it is also possible for the recess in the panel to be open in the direction of the force (e.g. downwards) (related to the position of the panel in the structure).
  • the cross-sectional area of the recess of the plate and/or the outer cross-sectional area of the sleeve may have the shape a circle, an ellipse, a square or a rectangle. Other shapes are of course also possible. It is also possible here to combine different cross-sectional shapes and preferably to avoid point contact between the sleeve and the plate. For example, with a circular outer cross-sectional area of the sleeve, the cross-sectional area of the plate can have an elliptical shape.
  • cross-sectional area of the recess is greater than the outer cross-sectional area of the socket refers to a projection of the recess in the direction of the longitudinal axis of the reinforcement cage and implies that the socket can be pushed through the slab, regardless of the shape of the slab.
  • the sleeve can be made of a pressure-resistant material, in particular a plastic material or a metallic material, for example an iron or steel material.
  • the transverse force mandrel can be formed from a shear-resistant material, in particular a fiber-reinforced plastic material or a metallic material, for example a steel material.
  • the transverse force mandrel can be inserted into the sleeve essentially without play, in particular essentially without play, in at least one direction, but also in both directions, orthogonal to the longitudinal extent of the sleeve and the transverse force mandrel.
  • the term "backlash-free" means that the shear force mandrel can be pushed into the sleeve without being clamped, but the longitudinal axes of the shear force mandrel and sleeve are tilted (vertically and/or horizontally). relative to one another when the shear force mandrel is inserted into the sleeve is less than 5°, in particular less than 1°.
  • the sleeve may have a spacer, a collar, or a portion at one end, the outer cross-sectional area of which is larger than the cross-sectional area of the recess of the plate.
  • a spacer is suitable, for example, for ensuring that the concrete cover is maintained.
  • the sleeve can then only be pushed into the reinforcement element until the spacer, the collar, or said partial area hits the plate.
  • the end of the sleeve with the spacer, collar, or said portion is intended for embedding flush with the edge in the concrete of the first component.
  • the spacer can also be arranged and possibly fastened to a nail plate or the plate.
  • the recess of the plate or the region of the sleeve that appears in the recess of the plate can have at least partially circumferential padding on the inside (or outside) made of a preferably pressure-elastic material, in particular a rubber-elastic material. Due to the fact that the recess in the plate is larger than the outer cross-section of the sleeve (inclinability), it is advantageous if the sleeve rests against the plate for load application. This position securing does not necessarily have to be carried out with a pressure-elastic material. A spring steel element, a corresponding part made of hard plastic, or a rubber band that is guided over the plate and encloses the sleeve on both sides would also be possible, for example.
  • the invention also relates to a structure according to claim 8.
  • the shear force mandrel and the reinforcement cage are typically, but not necessarily, oriented with their longitudinal axes horizontal.
  • both the first and the second component to each have a reinforcement element with an inserted sleeve, in which case the transverse force mandrel is then inserted with its opposite ends into a respective sleeve.
  • this can be recommended for two connected plate-shaped components.
  • the invention relates to a use according to claim 9 and a set of components according to claim 10.
  • the reinforcement element is typically fixed in the context of an overall reinforcement of a first component in this, the sleeve is then inserted into the reinforcement element, aligned and also fixed, and Finally, the entire reinforcement, including the reinforcement cage and sleeve, is concreted in, whereby tilting between the reinforcement cage and sleeve in the context of the alignment is ultimately rigidly fixed by the concrete enclosing and hardened the sleeve.
  • first component 1 made of reinforced concrete and a second component 2, which are connected to each other.
  • An elongate sleeve 3 and a transverse force mandrel 4 are set up for the purpose of the connection.
  • the sleeve 3 is embedded in the concrete of the first component 1 flush with the edge.
  • the shear force mandrel 4 is pushed into the sleeve 3 from the outside,
  • FIG. 1 A comparative view of figures 1 and 2 it can be seen that the sleeve 3 is inserted or inserted into a reinforcement element 5 .
  • the reinforcement element 5 is formed with an elongate reinforcement cage 6 and a plate 9 arranged on an end face 7 of the reinforcement cage 6 .
  • the plate 9 is firmly connected to the reinforcement cage 6 .
  • the plate 9 is flat and is essentially orthogonal to the longitudinal extent of the sleeve 3.
  • the plate 9 has a recess 10 through which the sleeve 3 can be pushed, provided that the part of the sleeve 3 pushed through is placed inside the reinforcement cage 6 .
  • the recess 10 of the plate 9 has a cross-sectional area which is so much larger than the outer cross-sectional area of the sleeve 3 that the sleeve 3 is at least 1° relative to the reinforcement cage 6, measured between at least one longitudinal axis 11 of the reinforcement cage 6 and a central axis 12 of the sleeve 3, is pivotable.
  • said axes are coaxial to each other.
  • the cross-sectional area of the recess 10 of the plate 9 and the outer cross-sectional area of the sleeve 3 have the shape of a circle.
  • the sleeve 3 and the transverse force mandrel 4 are made of stainless steel.
  • Shear force mandrel 4 and sleeve 3 are drawn with significantly different outside and inside diameters, which is due to the clarity of the drawing.
  • the shear force mandrel 4 can be inserted into the sleeve essentially without play, in particular essentially without play, in at least one direction orthogonal to the longitudinal extent of the sleeve 3 and the shear force mandrel 4, for example vertically.
  • the sleeve 3 has a partial region 13 at one end, the outer cross-sectional area of which is larger than the cross-sectional area of the recess 10 of the plate 9 .
  • the recess 10 of the plate 9 in this exemplary embodiment has a padding 14 made of an elastic material, in particular a rubber-elastic material, which is at least partially circumferential on the inside.
  • shear force mandrel 4 is mounted in a footfall sound insulation box 15, which in turn is installed or concreted in the second component 2 .
