Definitions

  • the invention relates to a connecting arrangement for the force-transmitting connection of a first force-absorbing structural part to a second force-absorbing structural part of the type specified in the preamble of claim 1 and a structure with such a connecting arrangement.
  • the EP 4 036 338 A1 discloses a generic connection arrangement for the force-transmitting connection of a first force-absorbing structural part to a second force-absorbing structural part.
  • the first force-absorbing structural part can be, for example, a balcony slab and the second force-absorbing structural part can be a building ceiling.
  • the connection arrangement is intended for the subsequent connection of the first force-absorbing structural part to the second force-absorbing structural part.
  • the first force-absorbing structural part can, for example, be manufactured as a prefabricated part in the prefabricated part factory and transported to the construction site. There is no need to cast and harden the first force-absorbing part of the structure on site. This means that crane times can be kept short and the structure can be constructed quickly.
  • the object of the invention is to create a connection arrangement of the generic type which enables tolerances on the pressure element to be compensated for in a simple manner.
  • a further object of the invention is to provide a structure that enables tolerances on the pressure element to be compensated for in a simple manner.
  • connection arrangement by a connection arrangement with the features of claim 1.
  • structure the task is solved by a structure with the features of claim 11.
  • Pressure elements of such arrangements are designed in accordance with relevant standards so that the forces acting on the pressure elements can be safely transmitted with an appropriate safety factor. This requires that all pressure elements taken into account in the calculation also participate in the load transfer, i.e. are connected to both parts of the structure in a force-transmitting manner.
  • the invention provides that a rod-shaped section of the pressure element, which is intended for arrangement in a joint between the parts of the building, has a flow section with a constant, opposite the rod-shaped section has a reduced cross-sectional area.
  • the flow section is a section in which the elastic limit of the metallic material is exceeded earlier than in the remaining rod-shaped section. If not all pressure elements contribute equally to the load transfer due to tolerances, then an excessively large force acts on the pressure elements through which the load is transferred, for which the pressure element is not designed. As a result, the elastic limit of the material in the flow section can be exceeded and the material in the flow section deforms plastically under the action of pressure. The length of the flow section of this pressure element is reduced until a remaining distance to one of the structural parts is overcome on at least one further pressure element and the at least one further pressure element lies between the structural parts in a pressure force-transmitting manner.
  • the cross section of the flow section and the length of the rod-shaped section are advantageously coordinated with one another in such a way that the material in the flow section reaches its elastic limit under pressure before the rod-shaped section buckles. This can ensure that the pressure element does not fail due to buckling before the flow section reaches its elastic limit and deforms plastically due to the pressure load.
  • the adjustment of the cross section can be an adjustment of the size and/or the shape of the cross section.
  • buckling of the rod-shaped section can also be prevented in another way, for example by reducing the buckling length using supporting elements.
  • the rod-shaped section does not have to bridge the entire parting line. It can be provided that further elements are arranged in the parting line, which form part of the pressure element.
  • fastening elements for the rod-shaped section for example a nut on which the rod-shaped section is held, can be arranged in the parting line.
  • the cross-sectional area of the flow section is advantageously 55% to 80%, in particular 56% to 76%, of the largest cross-sectional area of the rod-shaped section.
  • the rod-shaped section is preferably made of stainless steel or high-strength steel.
  • the width of the flow section is advantageously 15% to 25%, in particular 17% to 23%, of the largest outside diameter of the rod-shaped section.
  • the width of the flow section should be as large as possible in order to compensate for sufficiently large tolerances.
  • the width of the flow section must not be so large that the rod-shaped section can buckle in the flow section.
  • the width of the flow section is in particular 3 mm to 15 mm.
  • the width of the flow section is in particular at least 5 mm, advantageously at least 8 mm.
  • the width of the flow section is at most 14 mm, advantageously at most 13 mm, in particular at most 10 mm.
  • the flow section is advantageously delimited by a paragraph on at least one side.
  • the flow section is preferably delimited on both sides by a shoulder.
  • the flow section merges with a wall that runs approximately perpendicular to the longitudinal central axis of the rod-shaped section into the area of the rod-shaped section adjacent to the flow section.
  • the flow section is formed in particular by a straight recess.
  • the flow section is advantageously a groove in the rod-shaped section.
  • the flow section forms one end of the rod-shaped section and is designed as a straight pin.
  • a comparatively constant deformation characteristic of the pressure element can be achieved through a flow section with a constant cross section, which merges via a shoulder into the adjacent sections of the rod-shaped section. Due to the increase in diameter of the flow section resulting from the deformation, a Strictly linear course of the force-strain diagram is not possible even with a constant cross-section of the flow section.
  • the rod-shaped section is advantageously designed as a smooth rod or as a threaded rod, the smooth rod or threaded rod having a constant outside diameter. This makes it possible to ensure in a simple manner with little use of material that the material of the rod-shaped section first reaches the elastic limit in the flow section.
  • the pressure element is in particular a pressure rod.
  • the rod-shaped section can be guided from the joint with the same material and diameter into one of the force-absorbing structural parts or both force-absorbing structural parts and cast there.
  • the pressure rod can be a long rod of uniform material, which can have a constant outside diameter with the exception of the flow section.
  • the rod-shaped section and possibly an adjacent section of the compression rod can be made of a different material than the section intended for embedding in a force-absorbing structural part.
  • at least the rod-shaped section i.e. the area of the compression rod intended for arrangement in the parting line, and preferably a transition section adjacent thereto, is made of stainless steel. Adjacent sections of the compression bar may be formed from structural steel.
  • the compression rod can be designed as a smooth rod or can be provided with a thread or ribbing.
  • the pressure element comprises a pressure plate for embedding in a building part.
  • the pressure element comprises a pressure plate for embedding in the second structural part.
  • another arrangement with a pressure plate in the first part of the structure can also be provided. The pressure forces to be introduced can be introduced evenly into the surrounding concrete of the corresponding part of the structure via the pressure plate.
  • the pressure element advantageously comprises exactly one flow section. In an alternative embodiment, however, it can be provided that the pressure element comprises at least two flow sections. This allows larger tolerances to be compensated for.
  • connection arrangement is advantageously a connection arrangement for subsequent assembly of the first structural part on the second structural part.
  • the connection arrangement is advantageously designed such that the first force-transmitting structural part can be fixed to the second structural part after completion of the first force-transmitting structural part and the second force-transmitting structural part.
  • At least the first structural part can be a prefabricated part made of reinforcing steel, which is manufactured in a prefabricated parts factory and then transported to a construction site in order to be connected there to the second structural part.
  • the first structural part can be a steel part.
  • the first structural part can include several steel beams that form a supporting structure for a balcony or the like. Because both parts of the structure are first completed and then connected to each other, crane times can be kept to a minimum and the structure can be constructed quickly.
  • connection arrangement can also be advantageous for a first structural part, in which the first structural part is created on the construction site, for example using in-situ concrete, and in which the parts of the connection arrangement intended for embedding in the first structural part are already created during the construction of the first structural part are connected to the second part of the building.
  • the intended tolerance compensation of the pressure elements can also be advantageous for such structural parts constructed on site.
  • the building comprises a connection arrangement for the force-transmitting connection of a first force-absorbing structural part to a second force-absorbing structural part.
  • the width of the flow section is advantageously 3% to 15%, in particular 5% to 10%, of the width of the parting line.
  • the width of the flow section is advantageously 3 mm to 15 mm, in particular 3 mm to 10 mm. As a result, sufficiently large component tolerances can be compensated for and buckling of the pressure element in the flow section can advantageously be avoided.
  • the width of the flow section is in particular 3 mm to 15 mm.
  • the width of the flow section is in particular at least 5 mm, advantageously at least 8 mm.
  • the width of the flow section is at most 14 mm, advantageously at most 13 mm, in particular at most 10 mm.
  • insulating material in particular an insulating body, is arranged in the joint. However, it can also be provided that no insulating material is arranged in the joint.
  • the distance of the flow section to the first part of the building is advantageously less than 50% of the width of the parting joint, in particular less than 40% of the width of the parting joint.
  • the flow section is preferably not arranged in the middle of the parting line, but rather closer to the first part of the building.
  • the first structural part is advantageously a structural part fixed to the second structural part, for example a cantilevered structural part such as a balcony or the like.
  • the distance of the flow section to the end of the rod-shaped section arranged close to the first structural part is advantageously less than 20% of the width of the parting line.
  • an arrangement close to the second part of the building can also be advantageous.
  • Pressure elements with a flow section are particularly advantageous if the first force-absorbing structural part is connected to the second force-absorbing structural part via at least three pressure elements with a flow section. With at least three pressure elements, tolerances between the pressure elements can advantageously be compensated for over the flow section in such a way that over each pressure element the the same load is transferred, so that there is a uniform load transfer and overloading of individual pressure elements is avoided.

  • the first structural part is advantageously a steel part or a reinforced concrete part.

  • modules 40, 41, 42 are provided for connecting the first force-absorbing structural part 2 to the second force-absorbing structural part 3.
  • Each module 40, 41, 42 advantageously has at least two, in particular at least three, tensile force-transmitting elements.
  • Each tensile force-transmitting element can be formed, for example, by a first tension rod 9 and a second tension rod 10.
  • the pressure rods 19 are shown as pressure elements.
  • the other force-transmitting elements are not shown.
  • Each module 40, 41, 42 has a width h.
  • the width h is advantageously at least 30 cm, in particular at least 50 cm.
  • Adjacent compression rods 19 of a module 40, 41, 42 are at a distance g from one another.

  • this is in Fig. 9
  • Module 40 shown above is arranged so that the rod-shaped sections 22 rest on the first force-absorbing structural part 2 in a force-transmitting manner.
  • the rod-shaped sections 22 in the second, middle module 41 have a distance x from the second force-absorbing structural part 2, which is shown enlarged in the illustration.
  • the third module 42 is arranged slightly inclined to the transverse direction 29.
  • the longitudinal axis 25 in the rod-shaped section 22 forms an angle ⁇ with the transverse direction 29. This means that only the in Fig. 9
  • the compression rod 19 of the third module 42 shown above is attached to the first force-absorbing structural part 2.
  • the in Fig. 9 In the installation situation shown as an example, only three of the six compression rods 19 contribute to load transfer. The further compression rods 19 have no contact with the first force-absorbing structural part 2.
  • the Cross sections of the compression rods 19 in the flow sections 23 are designed such that due to the excessive force acting on the three compression rods 19 that actually contribute to load transfer, the yield point in these flow sections 23 is exceeded and the material deforms plastically. This reduces the length of the rod-shaped sections 22 of these compression rods 19.
  • the permissible tolerances and the width b of the rod-shaped sections 23 ( Fig.
  • the length e of the rod-shaped sections 22 is advantageously matched to the diameter d of the rod-shaped sections 22 and the diameter a in the flow section 23 so that the yield point in the flow section 23 is reached before the rod-shaped sections 22 buckle. This makes it easy to ensure that all pressure elements 8 contribute to load transfer.
  • Fig. 10 shows schematically the force-displacement diagram of a rod-shaped section 22 with increasing pressure load.
  • the force F initially increases approximately proportionally to the distance s. Then the rod-shaped section 22 begins to buckle and fails after reaching a distance si with a force Fi.
  • the solid line 44 shows the force-distance curve in a rod-shaped section 22 with a flow section 23 according to the invention.
  • the force F increases according to line 43 approximately proportionally to the distance s.
  • the material in the flow section 23 reaches its elastic limit and begins to deform plastically, i.e. to flow.
  • the deformation path increases comparatively significantly as the force continues to increase.
  • the increase in force F is slowed down.
  • the slope of line 44 is smaller after force F 2 has been exceeded as the slope of line 43.
  • the rod-shaped section 22 buckles and breaks.
  • the deformation path s 2 is greater than the deformation path si.
  • the force after which the rod-shaped section 22 with flow section 23 buckles can also be slightly smaller than the force Fi at which a rod-shaped section 22 without flow section 23 buckles. The flatter load increase when the force Fi is exceeded enables tolerance differences to be compensated for.
  • connection arrangement 1 In the exemplary embodiment is in the Figures 1 and 2 a possible embodiment of a connection arrangement 1 is shown.
  • the rod-shaped section 22 according to the invention with a flow section 23 can be independent of the design of the connecting arrangement 1 and regardless of whether the connecting arrangement 1 is intended for the subsequent connection of a first force-absorbing structural part 2 to a second force-absorbing structural part 3, or whether the first force-absorbing structural part 2 made on the second force-absorbing structural part 3, for example cast from concrete, may be advantageous.
  • Other designs of pressure elements 8, 45 can also be advantageous.
  • the rod-shaped sections 22 can have a constant outside diameter or sections with different outside diameters outside the flow section 23 and can be designed as a smooth rod, threaded rod, reinforcing steel rod or any combination of these designs.
  • the anchoring of the pressure elements 8, 45 in the second force-absorbing structural part 3 can be selected appropriately and is not limited to the embodiments and combinations with rod-shaped sections 22 shown.
  • the anchoring of the pressure elements 8, 45 in the second force-absorbing structural part 3 can be designed, for example, as a pressure rod 19, pressure plate 35 or in another suitable manner for introducing pressure forces and can be combined in any way with the described designs of rod-shaped sections 22.
