Definitions

  • the present invention relates to a device for force-transmitting connection of a first supporting building part, in particular a building wall, to a second supporting building part, in particular a stair part.
  • This device comprises a sleeve assigned to the second supported building part, which in the installed state, starting from a front edge of the second supported building part facing a joint left between the first and second building part, extends horizontally into the second supported building part and a peripheral sleeve wall, a sleeve base , has an inner region defined by the sleeve wall and the sleeve base and a sleeve opening opposite the sleeve base.
  • the sleeve In the installed state of the device, the sleeve extends into the second supported building part in such a way that the sleeve opening is arranged in the area of the front edge and the sleeve base is arranged inside the second supported building part. Furthermore, the device has a support element which, when installed, extends horizontally through the joint between the first building part and the second building part and which, when installed, is partially accommodated in the inner region of the sleeve. Furthermore, this device comprises at least one force transmission element assigned to the second supported building part, which is used to anchor the sleeve in the second supported building part.
  • Such a device is, for example, from DE 10 2013 100 356 A1 out.
  • Such devices are used in particular wherever forces have to be transmitted between two building parts on the same level, namely above all a weight force acting on the support element from the second supported building part, bending moments acting on the support element and transverse forces.
  • These building parts at the same level can be, for example, a stair part and a building wall made of concrete.
  • the sleeve When constructing the concrete stair section, the sleeve is integrated into a formwork for the stair section at the desired position before liquid concrete is poured into the formwork. After the liquid concrete has hardened, the sleeve wall and the sleeve base are therefore surrounded by the hardened concrete, so that the carrier element can be partially inserted through the exposed sleeve opening, i.e. not surrounded by concrete, into the inner region of the sleeve and can be stored there.
  • the stair part can either be created in the precast concrete plant and then transported to the construction site or created directly on the construction site.
  • the support element In the installed state of the device, the support element extends into the first part of the building, in particular into the building wall.
  • a joint forms between the building parts when the second supporting building part is connected to the first supporting building part. If the stair section is connected to the building wall, the support element must transfer the weight of the stair section to the building wall, which leads to particularly high loads in the area of the front edge of the supported stair section, i.e. in the area of the stair section adjacent to the joint.
  • the force transmission element is provided, which in the device known from the prior art in the installed state starts from a first side of the outer side of the sleeve wall on both sides laterally of the outer side of the sleeve wall into an area on a second side of the outer side of the sleeve wall opposite the first side and thus ensures better anchoring of the carrier element and the sleeve in the stair part.
  • the carrier element can be designed either as a mandrel made of solid material or as a hollow profile.
  • the device known from the prior art has the disadvantage that in its installed state, with lifting and horizontally acting forces, cracks can form in the material of the second part of the building, in particular the stair part, even below the working load level.
  • Such lifting forces arise, for example, through the use of a heavy part of the staircase and/or a geometry of the part of the staircase that is unfavorable for power transmission. They cause the stair part on its side facing away from the building wall downwards, ie tilting in the direction of gravity, while the support element mounted in both the stair part and in the building wall is raised in the building wall upwards, ie against the direction of gravity. In the event of an unfavorable load on the heavy stair section, horizontal forces can also occur.
  • a second force transmission element could be provided which, in the installed state, extends from the second side of the outside of the sleeve wall on both sides of the outside of the sleeve wall into an area on the first side of the outside of the sleeve wall, opposite the second side.
  • this second force transmission element would have to be arranged as close as possible to the front edge of the second part of the building in order to reduce or completely prevent the formation of cracks in the second part of the building in the event of lifting and/or horizontally acting forces.
  • the second force-transmission element would have to consist of stainless steel instead of cheaper reinforcing steel or be covered with an anti-corrosion layer in order to prevent corrosion of this force-transmission element.
  • this would uneconomically increase the manufacturing cost of the device.
  • the object of the present invention is therefore to provide a device which enables sufficient absorption and transmission of lifting and/or horizontally acting forces in order to thereby reduce crack formation in the material of the second supported building part or even completely avoided, without uneconomically increasing the manufacturing costs of the device.
  • the sleeve has at least one first anchoring element protruding in relation to the sleeve for its positive anchoring in the second supported building part on a first side of the outside of the sleeve wall.
  • this first anchoring element is surrounded by the material, in particular the hardened concrete, of the second part of the building and thereby anchors the sleeve in the second part of the building.
  • the first anchoring element is able to absorb lifting forces acting between the building parts and transmit them to the sleeve and the carrier element.
  • cracking in the material of the second part of the building is reduced or even completely avoided.
  • This first anchoring element can have a first base body, which in the installed state of the device is essentially oriented in a main bearing direction, and at least one first projection protruding in relation to the first base body.
  • This main bearing direction acts mainly against the direction of gravity.
  • the first base body and thus the first anchoring element is arranged on an upper outer side of the sleeve wall when the device is installed.
  • the sleeve can also have a plurality of first anchoring elements which protrude in relation to the sleeve. For example, a particularly heavy stair section may require the presence of a plurality of first anchoring elements.
  • the carrier element can be made of stainless steel, hot-dip galvanized mild steel or the like.
  • a further advantageous embodiment of the device according to the invention provides that the sleeve wall has at least one with the first Main body of the first anchoring element has connected wall section with increased wall thickness. This means that this wall section has a greater wall thickness than the remaining sleeve wall.
  • This wall section thus represents a continuation of the first anchoring element, which, starting from the first base body, can run partly on the outside of the sleeve wall, in particular partly over a second side of the outside of the shell wall.
  • the sleeve wall can also have two wall sections with increased wall thickness connected to the first base body of the first anchoring element, with a first wall section starting from the first base body partially extending over the second side of the outside of the sleeve wall and a second wall section starting from the first base body partially extending over one of the second side opposite third side of the outside of the sleeve wall.
  • An advantageous further development of the device according to the invention provides that on the second side of the outside of the sleeve wall at least one second anchoring element is arranged which protrudes in relation to the sleeve wall for positively locking anchoring of the sleeve in the second supported building part, which serves to absorb horizontally acting forces.
  • This second anchoring element comprises a second base body and at least one second projection protruding in relation to the second base body, with the second base body being aligned essentially perpendicularly to the main carrying direction when the device is installed.
  • the second base body and thus the second anchoring element is arranged on a right-hand or left-hand area of the outside of the sleeve wall when the device is installed.
  • the projection of the first and/or second anchoring element enables the respective anchoring element to be interlocked with the material of the second part of the building, in particular the part of the staircase.
  • the sleeve wall can have four side walls and a rectangular cross section orthogonal to its longitudinal extent.
  • the first base body of the first anchoring element preferably runs perpendicular to the longitudinal extension of the sleeve along a first side wall of the sleeve wall.
  • this first side wall is located on the aforementioned first side of the outside of the sleeve wall.
  • the second base body of the second anchoring element preferably runs perpendicular to the longitudinal extension of the sleeve along a second side wall of the sleeve wall.
  • this second side wall is on the aforementioned second side of the outside of the shell wall.
  • the first and the second side wall of the sleeve wall preferably enclose an angle of essentially 90° with respect to one another, which means that the first side wall is oriented essentially perpendicular to the second side wall.
  • the previously described first wall section with increased wall thickness, starting from the first base body runs partially over the second side wall of the sleeve wall and the second wall section with increased wall thickness, starting from the first base body, runs partially over a third side wall of the sleeve wall opposite the second side wall, said third side wall being on the aforesaid third side of the outside of the sleeve wall.
  • first and/or second anchoring element each have at least one projection which protrudes in relation to the base body of the respective anchoring element, the anchoring of the sleeve in the material of the second part of the building is improved.
  • the first and/or the second anchoring element can also have a plurality of projections protruding in relation to the respective base body.
  • the first projection and/or the second projection are designed as ribs running essentially perpendicular to the longitudinal extent of the sleeve.
  • Such a rib can extend along the entire base body of the respective anchoring element and/or have a wedge shape, the width of which increases in the direction of the sleeve wall of the sleeve. Due to the wedge shape, the interlocking of the respective anchoring element with the material of the second part of the building, in particular the stair part, is improved.
  • the force transmission element can be fixed at least indirectly non-positively, frictionally and/or positively on the outside of the sleeve wall, in particular on an area of the first side of the outside of the sleeve wall adjoining the sleeve opening. This is to ensure that the force transmission element activates the areas of the second supported building part that it acts on and can thus transmit the corresponding forces from the support element and the sleeve.
  • the force transmission element when the force transmission element is fixed at a distance from the sleeve opening below the required minimum concrete cover, the force transmission element must be made of stainless steel or have corrosion protection. It is therefore advisable to set the force transmission element at a distance from the sleeve opening above the required minimum concrete cover, in order to be able to use a force transmission element made of cheaper reinforcing steel.
  • the force transmission element comprises a loop-like middle part that is at least indirectly fixed on the first side of the outside of the sleeve wall and two side parts branching off from the loop-like middle part, the two side parts being essentially parallel to the longitudinal extent of the sleeve in the direction of the sleeve base get lost.
  • the wording "at least indirectly” means in this context that the loop-like central part can be fixed either directly or indirectly on the first side of the outside of the sleeve wall. In the former case, the loop-like central part can act on the sleeve directly and thus run along the first side of the outside of the sleeve wall.
  • the loop-like middle part and the two side parts arranged on the loop-like middle part can be formed from a one-piece reinforcement bar.
  • the loop-like middle part is preferably fixed with the interposition of at least one pressure deflection element and thus indirectly on the first side of the outside of the sleeve wall. Due to its particularly advantageous configuration, this pressure deflection element ensures the possibility of providing an optimal contact between the reinforcing bar and the outside of the sleeve.
  • This pressure deflection element must be sufficiently pressure-resistant to transmit the forces directly between the carrier element via the sleeve wall to the pressure deflection element and from there to the reinforcing bar.
  • the device comprises at least one pressure deflection element fixed on the first side of the outside of the sleeve wall and two L-shaped force transmission elements connected to the pressure deflection element, each with a first leg and a second leg that is essentially perpendicular to the first leg .
  • the first legs each extend out from the first side of the outside of the sleeve wall laterally into an area on the fourth side of the outside of the sleeve wall opposite the first side.
  • one of the first legs of the reinforcing rods runs in particular along the second side of the outside of the sleeve wall and/or essentially parallel to the main bearing direction.
  • first legs of the reinforcing rods runs in particular along the third side of the outside of the sleeve wall and/or essentially parallel to the main load-bearing direction.
  • the second legs each run in the direction of the sleeve base.
  • the second limbs can protrude beyond the base of the sleeve and thereby overlap with a reinforcement in the concrete of the second supported building part when the device is installed.
  • the first legs of the force transmission elements are non-positively connected to the pressure deflection element, in particular on their side facing away from the second legs. This adhesion can B. be achieved by gluing, welding, latching and / or a headed bolt that leads through a hole in the power transmission element and the pressure element.
  • the force-transmitting elements are preferably L-shaped reinforcement rods made of, for example, metal or a metal alloy, in particular reinforcing steel or stainless steel.
  • the pressure deflection element can be made of metal or a metal alloy and/or can be made semi-elliptical, in particular semi-circular.
  • the device has a further advantageous embodiment Stress damping element, which at least partially runs around the outside of the sleeve wall and is preferably made of a material with reduced rigidity compared to concrete, in particular made of an elastomer.
  • the stress-damping element can be arranged between the latching means and the sleeve opening or between the latching means and the front edge of the second building part on the outside of the sleeve wall.
  • the force transmission element and/or the first anchoring element is arranged at a distance from the sleeve opening on the outside of the sleeve wall.
  • This spacing of the force transmission element from the sleeve opening or the front edge of the second building part means that structural steel or reinforcing steel can now be used as the material for the force transmission element instead of stainless steel, which is more susceptible to corrosion, but due to the distance caused by the stress damping element from the joint and the associated compliance with the required minimum concrete cover is sufficient.
  • the use of the very expensive stainless steel which makes the system unattractive, can be avoided.
  • the pressure deflection element By using a material with reduced stiffness compared to concrete for the stress-damping element, the forces acting on the front edge of the supported building part are not passed on 1:1 to the overlying material of the second building part, but to a reduced, ie buffered, extent.
  • the sleeve has on the outside of the wall a collar surrounding the sleeve opening, which collar can be used, for example, to fix the sleeve to a component formwork during the production of the second supported building part, so that when the material of the second part of the building the sleeve remains in the correct position.
  • the sleeve wall, the sleeve base, the first and/or second anchoring element, the latching means and/or the collar can be made in one piece from plastic, in particular injection-moulded, 3D-printed or milled plastic, which significantly simplifies the manufacture of the device.
  • the sleeve can be an injection molded part.
