Description

[0001] The invention relates to a structure with a connecting arrangement of the type specified in the preamble of claim 1.

[0002] EP 2 191 078 B1 discloses a connecting arrangement for two structural components, comprising a shear force rod. The shear force rod extends with one end section into a receptacle in which the shear force rod is horizontally movable in the longitudinal direction of the joint between the structural components during construction of the structure. This allows for the compensation of displacements between the structural components relative to one another. This is particularly advantageous for structural components that are prestressed. After an initial relative movement of the structural components, the shear force rod is filled, particularly in the receptacle. The structural components are then firmly connected to one another.

[0003] The invention is based on the object of providing a building with an advantageous structure.

[0004] This object is achieved by a structure having the features of claim 1.

[0005] It is provided that the connecting arrangement comprises at least one first connecting device and at least one second connecting device, which are designed differently. The at least one first connecting device comprises a shear force rod. The shear force rod is held in the two structural components to transmit forces acting in the vertical direction. The at least one second connecting device comprises a tension rod bridging the joint. The tension rod projects into a casting housing embedded in one of the structural components and is cast therein with a filling material that is different from the concrete of the structural component.

[0006] Because the connecting arrangement has at least one first connecting device and at least one second connecting device, the connecting devices of the connecting arrangement can be well designed and precisely dimensioned for the forces to be transmitted. By combining and selecting the connecting devices appropriately, the material requirements for the connecting arrangement can be kept to a minimum. Because the connecting arrangement comprises at least one first connecting device with a shear force rod, the two structural components can support each other vertically during construction of the structure. In particular, the at least one shear force rod is positioned in the two structural components after the structural components have been positioned. The structural components are in particular prestressed reinforced concrete components. The structural components are in particular prestressed after they have been positioned in the structure.The at least one tension rod is cast in particular after prestressing of the structural components.

[0007] In particular, the tension rod has a height, measured in the vertical direction, that amounts to a maximum of 70% of the internal height of the casting housing measured in the vertical direction at the tension rod. In particular, the tension rod has a width, measured in the longitudinal direction of the joint, that amounts to a maximum of 70% of the internal width of the casting housing measured in the longitudinal direction of the joint at the tension rod. As a result, the tension rod is movable in the casting housing in the vertical direction and in the longitudinal direction of the joint before the tension rod is cast. This allows for compensation of changes in the relative position of the structural components, which may occur, for example, due to the prestressing of the structural components.

[0008] In particular, the connecting arrangement is constructed from groups of connecting devices. Each group of connecting devices comprises, in particular, at least two first connecting devices, whose center axes are spaced apart by a distance measured in the longitudinal direction of the joint. In particular, a second connecting device is arranged between the two first connecting devices relative to the longitudinal direction of the joint. This arrangement is particularly suitable when the two structural components to be connected are building ceilings.

[0009] The connecting arrangement comprises, in particular, at least two first connecting devices, whose center axes are spaced apart from one another in the vertical direction. This allows bending moments to be effectively absorbed by the connecting device.

[0010] In particular, at least four first connecting devices are provided, the central axes of which are arranged in the corners of a rectangle, as seen in the transverse direction of the joint. In particular, at least one second connecting device is arranged within the rectangle. This arrangement is particularly advantageous for connecting a building ceiling to a wall.

[0011] In particular, a distance measured in the longitudinal direction of the joint between adjacent first connecting devices is at least 5 times the width of the tension rod.

[0012] The casting housing has, in particular, at least one filling opening for filling material and at least one ventilation opening, which are arranged on an outer side of the structural component in which the casting housing is embedded. The filling opening and the ventilation opening are, in particular, filled after the construction of the structure. Filling material can be filled into the casting housing via the filling opening. The ventilation opening enables the areas of the casting housing provided for this purpose to be completely filled. In particular, the filling opening and / or the ventilation opening are arranged on an upper side of the structural component.

[0013] The cross-sectional area of ​​the shear force bar of the second connecting device that is effective for load transfer is in particular larger than the cross-sectional area of ​​the tension bar of the first connecting device that is effective for load transfer. In particular, the cross-sectional area of ​​the shear force bar that is effective for load transfer is at least 1.5 times, in particular at least 2 times, the cross-sectional area of ​​the tension bar that is effective for load transfer. The cross-sectional area that is effective for load transfer is the cross-sectional area that is to be used for calculating the load-bearing capacity. In the case of a bar with an uneven surface, for example a bar with a thread or ribbing, the cross-sectional area in the area of ​​the thread or ribbing in particular does not need to be taken into account, but only the cross-sectional area that is continuous over the length of the bar.

[0014] Before grouting, the shear force bar can move relative to the holder, particularly in the vertical direction, by a maximum of 2 mm and in the longitudinal direction of the joint by at least 10 mm. Because the shear force bar can move relative to the holder in the vertical direction by a maximum of 2 mm, transverse forces can be transferred between the structural components to be connected via the shear force bar even before grouting. The structural components can support each other in the vertical direction via the shear force bar even before grouting and the complete curing of the tension rods of the second connecting device. In the horizontal direction, compensation for relative movement of the structural components is possible in order to prevent stresses on the shear force bar in the horizontal direction. For this purpose, the shear force bar is designed to be movable relative to the holder by at least 10 mm in the longitudinal direction of the joint. This allows normal relative movements between the structural components to be compensated.Relative movements of the structural components occur particularly when the structural components are prestressed.

[0015] In particular, the receptacle is formed in a receiving tube into which a receiving sleeve projects. The receiving tube is, in particular, a tube with a rectangular cross-section. In particular, the receiving tube accommodates the shear force rod. A diameter of the shear force rod is, in particular, at most 2 mm smaller than an inner width of the receiving sleeve measured in the longitudinal direction. In particular, the receiving sleeve is cast in the receiving tube. This allows a slight relative movement of the shear force rod with respect to the receptacle even after casting.

[0016] The at least one tension rod consists, in particular, at least partially, in particular entirely, of structural steel. The tension rod can have ribbing and / or a thread over at least part of its length.

[0017] The at least one shear force rod is made, in particular, at least partially, in particular entirely, of stainless steel. The at least one shear force rod has, in particular, a smooth surface, at least in the section protruding into the receptacle. Accordingly, the at least one shear force rod has no thread or ribbing, at least in the section protruding into the receptacle.

[0018] In particular, at least one of the structural components, in particular both structural components, is prestressed. In particular, at least one of the structural components, in particular both structural components, is prestressed precast concrete.

[0019] In particular, the tension bar and / or the shear bar in one of the structural components are embedded directly into the concrete of the structural component.

[0020] The embedment length of the tension bar in the structural component is, in particular, shorter than the embedment length of the shear bar in this structural component. Due to the comparatively long embedment length, tensile forces can be transferred effectively via the tension bar.

[0021] In particular, the tension rod and / or the shear force rod are screwed into an anchor sleeve embedded in the structural component. This allows the tension rod and / or the shear force rod to be mounted to the anchor sleeve of the structural component after the structural component has been cast and cured. This results in simplified assembly and transport of the structural component.

[0023] Fig. Figure 1 schematically shows a section of a building structure 1. The building structure 1 comprises a first structural component 2 and a second structural component 3, which are connected to one another via a connecting arrangement 4. For clarity, the structural components 2 and 3, as well as the parts of the connecting arrangement 4, are shown transparent in the schematic representations. A joint 7 is formed between the structural components 2 and 3. The joint 7 is bridged by the connecting arrangement 4. In the exemplary embodiment, the structural components 2 and 3 are building ceilings.

[0024] Structural components 2 and 3 are, in particular, prestressed concrete elements, particularly prestressed precast concrete elements. Structural components 2 and 3 are positioned at the specified location during the construction of structure 1 and then prestressed.

[0025] The structure 1 has a longitudinal joint direction x. The longitudinal joint direction x runs in the longitudinal direction of the joint 7, in particular, the longitudinal joint direction x runs horizontally. The structure 1 has a transverse joint direction y. The transverse joint direction y is directed perpendicular to the longitudinal joint direction x. The structure 1 has a vertical direction z. The longitudinal joint direction x and the transverse joint direction y run, in particular, perpendicular to the vertical direction z.

[0026] The connecting arrangement 4 comprises a first connecting device 5 and two second connecting devices 6a and 6b. The first connecting device 5 and the two second connecting devices 6a and 6b are designed differently. In the exemplary embodiment, the first connecting device 5 and the two second connecting devices 6a and 6b are arranged at the same height. The first connecting device 5 is arranged between the two second connecting devices 6a and 6b.

[0027] The first connecting device 5 and the two second connecting devices 6a and 6b form a group of connecting devices 5, 6a, 6b. In particular, the connecting arrangement 4 is constructed from several groups of connecting devices 5, 6a, 6b, which are arranged at a distance from one another in the longitudinal direction x of the joint.

[0028] The first connecting device 5 comprises a shear force rod 16 that projects into a receptacle 17. In the exemplary embodiment, one end of the shear force rod 16 is embedded in the second structural part 3. The receptacle 17 is embedded in the first structural part 2. The shear force rod 16 projects into the receptacle 17. The shear force rod 16 is, in particular, embedded directly or indirectly in the receptacle 17, as will be described in more detail below. The receptacle 17 is connected, in particular, via a filling channel 40 to an upper side 15 of the first structural part 2.

[0029] The second connecting devices 6a, 6b each have a tension rod 8. The tension rod 8 is each embedded in the second structural part 3. The second connecting devices 6a, 6b each have a casting housing 11 into which the tension rod 8 projects. The casting housings 11 are embedded in the first structural part 2. Each casting housing 11 has a filler opening 12 and a vent channel 13 with a vent opening 14. The filler opening 12 and the vent opening 14 are arranged on an upper side 15 of the first structural part 2. The filler opening 12 is arranged at the end of the casting housing 11 remote from the joint 7. The vent opening 14 is arranged close to the joint 7. The casting housing 11 has a fastening plate 20 which is arranged flush with the joint 7.

[0030] The tension rod 8 may have ribbing and / or - at least over part of its length - a thread. Fig. 1 schematically shows only the section of the tension rod 8 with ribbing arranged in the second structural part 3. In particular, the tension rod 8 has a uniform ribbing or no ribbing over its entire length. Fig. 11 shows the tension rod 8 with a continuous thread 29.

[0031] Fig. 2 shows a plan view of the connection arrangement 4. How Fig. As shown in Figure 2, the second connecting device 6a has a central axis 22. The second connecting device 6b has a central axis 23. The central axes 22 and 23 are spaced apart by a distance m. The distance m is measured in the longitudinal joint direction x. The central axes 22 and 23 are the central axes of the encapsulation housings in the section into which the tension rod 8 extends.

[0032] The first connecting device 5 has a central axis 26. The central axis 26 is the central axis of the receptacle 17 in the section into which the transverse force rod 16 extends. The central axis 26 is arranged between the central axes 22 and 23 and runs parallel to them. The central axis 26 is at a distance n from the central axis 22. The central axis 26 is at the same distance n from the central axis 23.

[0033] The tension rod 8 is embedded in the second structural part 3 over an embedment length s. The embedment length s is measured in the transverse joint direction y. The shear force rod 16 is embedded in the second structural part 3 over an embedment length t. The embedment length s is greater than the embedment length t. In particular, the embedment length s is at least 1.5 times the embedment length t. The embedment length s, t is the length of the tension rod 8 or the shear force rod 16, over which the tension rod 8 or the shear force rod 16 is enclosed by the material of the second structural part 3 in a force-transmitting manner.

[0034] The tension rods 8 are cast in the casting housings 11 with backfill material 30. The tension rods 8 are embedded in the backfill material 30 and surrounded by it in a force-transmitting manner. The backfill material 30 is different from the concrete of the structural component 2. The backfill material 30 can be, for example, mortar or epoxy resin.

[0035] The casting housing 11 has an inner width f. The tension rod 8 has a width e. In the exemplary embodiment, the width e of the tension rod 8 corresponds to the diameter of the tension rod 8. The inner width f and the width e are measured in the longitudinal joint direction x. The width e is smaller than the inner width f. As a result, the tension rod 8 is movable in the longitudinal joint direction x relative to the first structural part 2 before the tension rod 8 is cast in the casting housing 11. The inner width f is measured in a region of the casting housing 11 into which the tension rod 8 extends. The inner width f determines the possible movement of the tension rod 8 in the casting housing 11 in the longitudinal joint direction x. The width e is in particular at most 70% of the inner width f of the casting housing 11.

[0036] The distance m between adjacent first connecting devices 6a and 6b is in particular at least 5 times the width e of the tension rod 8.

[0037] The Fig. 3 to 5 show the receptacle 17 of the first connecting device 5. The receptacle 17 comprises a receiving tube 19. In the exemplary embodiment, the receiving tube 19 is formed with a rectangular cross-section. A fastening plate 27 is fixed to the receiving tube 19. In the exemplary embodiment, the fastening plate 27 has fastening openings 28 for fixing to a formwork. The filling channel 40 is in the Fig. 3 to 5 not shown.

[0038] A receiving sleeve 18 is arranged in the receiving tube 19. In the installed state before grouting, the receiving sleeve 18 is movable in the receiving tube 19 in the longitudinal direction x of the joint.

[0039] The receiving tube 19 has an inner width k measured in the longitudinal direction x of the joint and an inner height h measured in the vertical direction z. The receiving sleeve 18 has an inner width r measured in the longitudinal direction x of the joint. The inner width k and the inner height h are dimensioned such that the shear force rod 16, before casting, can move relative to the receptacle 17 in the vertical direction z by a maximum of 2 mm and in the longitudinal direction x by a minimum of 10 mm. In particular, the shear force rod 16 is not movable relative to the receiving sleeve 18 within the manufacturing tolerances. In particular, the receiving tube 19 can move relative to the receptacle 17 in the vertical direction z by a maximum of 2 mm and in the longitudinal direction x by a minimum of 10 mm.

[0040] In the exemplary embodiment, the receiving sleeve 18 is designed with a circular inner cross-section. In particular, the inner cross-section of the receiving sleeve 18 corresponds to the cross-section of the shear force rod 16. In the exemplary embodiment, the receiving sleeve 18 has an inner diameter a.

[0041] The Fig. 6 and Fig. 7 shows the shear force rod 16. The shear force rod 16 has a width i measured in the longitudinal joint direction x and a height g measured in the vertical direction z. In the exemplary embodiment, the width i and the height g are equal. In the exemplary embodiment, the shear force rod 16 is designed as a cylindrical rod with a constant outer diameter b. The shear force rod 16 is made of steel, in particular stainless steel. In the exemplary embodiment, the shear force rod 16 has a smooth surface over its entire length.

[0042] The outer diameter b of the shear force rod 16 is, in particular, at most 2 mm smaller than the inner width r of the receiving sleeve 18. The shear force rod 16 is therefore only slightly movable relative to the receiving sleeve 18 in the longitudinal direction x of the joint. To compensate for relative movements of the structural components 2 and 3 before the receiving sleeve 18 is cast in the receptacle 17, the shear force rod 16, in particular, moves with the receiving sleeve 18 in the longitudinal direction x of the joint relative to the receptacle 17.

[0043] The Fig. Figures 8 to 10 show the encapsulated housing 11. In the exemplary embodiment, the filling opening 12 is formed at an upwardly extending end portion of the encapsulated housing 11. The venting channel 13 branches off from the interior of the encapsulated housing 11 near the mounting plate 20.

[0044] How Fig. 9 shows, the fastening plate 20 has fastening openings 21 which can be used for fixing to a formwork during the manufacture of the first structural part 2.

[0045] The tension rod 8 has a height c measured in the vertical direction z, as Fig. 11. In particular, the tension rod 8 has a substantially round cross-section. In the exemplary embodiment, the tension rod 8 has a diameter u. The tension rod 8 is made, in particular, of steel, in particular of structural steel.

[0046] How Fig. 9 also shows, the encapsulated housing 11 has an internal height d. The internal height d is in particular at most 2 mm greater than the height c ( Fig. 11) of the tension rod 8. The encapsulated housing 11 has the inner width f. The inner width f is in particular at least 10 mm larger than the width e ( Fig. 2) of the tension rod 8. The internal height d and the internal width f are measured in an area of ​​the potting housing 11 into which the tension rod 8 extends.

[0047] The diameter u of the tension rod 8 is smaller than the diameter b of the shear force rod 16. The cross-sectional area of ​​the shear force rod 16 effective for load transfer is larger than the cross-sectional area of ​​the tension rod 8 effective for load transfer. In particular, the cross-sectional area of ​​the shear force rod 16 effective for load transfer is at least 1.5 times, in particular at least 2 times, the cross-sectional area of ​​the tension rod 8 effective for load transfer.

[0048] During the construction of the building 1, the building components 2 and 3 are first positioned relative to one another. At least one shear bar 16 is embedded in the second building component 3 and projects into the receptacle 17, in particular into the receptacle sleeve 18 in the receptacle 17. At least one tension bar 8 is embedded in the second building component 3 and projects into the casting housing 11 in the first building component 2. The building components 2 and 3 are in particular prestressed. After any movement of the building components 2 and 3 relative to one another, the tension bars 8 are cast in the casting housings 11. For this purpose, filling material 30, for example mortar or epoxy resin, is poured in via the filling opening 12 until the filling material 30 has filled the casting housing 11 up to the vent opening 14. In particular, the receiving sleeve 18 is cast in the receptacle 17. For this purpose, the receptacle 17 can be moved via the filling channel 40 ( Fig. 1) are filled with backfill material 30. The backfill material 30 is different from the concrete of structural components 2 and 3. After the backfill material 30 has hardened, tensile forces can be transmitted via the tension rods 8.

[0049] In the Fig. 12 and Fig. Figure 13 schematically illustrates another embodiment of a structure 1. The same reference numerals designate corresponding elements in all embodiments. For elements not described in detail, reference is made to the corresponding description of the preceding figures.

[0050] The structure 1 comprises structural parts 2 and 3, which are connected to each other via a connecting arrangement 4. In the exemplary embodiment, the structural part 2 is a building ceiling and the structural part 3 is a wall. The connecting arrangement 4 from the Fig. 12 and Fig. 13 comprises a first connecting device 5 and four second connecting devices 6a, 6b, 6c, and 6d. The connecting arrangement 4 is designed in particular for transmitting transverse forces.

[0051] The first connecting device 5 and the four second connecting devices 6a, 6b, 6c, 6d form a group of connecting devices 5, 6a, 6b, 6c, 6d. The connecting arrangement 4 can be constructed from several groups of connecting devices 5, 6a, 6b, 6c, 6d arranged at a distance from one another in the longitudinal joint direction x.

[0052] The design of the first connecting device 5 corresponds to that of the first embodiment.

[0053] The encapsulated housings 11 of the second connecting devices 6a and 6c are connected to one another. In the exemplary embodiment, a connecting section 31 is provided for this purpose, which extends the encapsulated housing 11 and forms a continuous, curved channel. The encapsulated housings 11 of the second connecting devices 6b and 6d are connected to one another accordingly. The connecting devices 6a and 6b are arranged above the connecting devices 6c and 6d. The connecting device 6a has a central axis 22. The connecting device 6b has a central axis 23. The connecting device 6c has a central axis 24. The connecting device 6d has a central axis 25. The central axes 22, 23, 24 and 25 of the connecting devices 6a, 6b, 6c and 6d are in particular the central axes of the casting housings 11 of the connecting devices 6a, 6b, 6c and 6d in the areas in which the tension rods 8 extend.

[0054] When viewed in the transverse direction y of the joint, the central axes 23, 24, 25, and 26 lie at the corners of a rectangle. The first connecting device 5 is arranged within this rectangle. In particular, the central axis 26 of the first connecting device 5 is arranged centrally within the rectangle. However, an off-center arrangement can also be advantageous.

[0055] How Fig. 13 shows, the central axes 22 and 23 are at a distance m from each other, measured in the longitudinal direction x of the joint. The central axis 26 is at a distance n from the central axes 22 and 23, measured in the longitudinal direction x. The central axes 24 and 25 are arranged in the vertical direction z below the central axes 22 and 23 and are at a distance m from each other and a distance n from the central axis 26. The central axes 24 and 25 are in Fig. 13 is shown for clarification.

[0056] How Fig. 13 also shows, the tension rods 8 of the connecting devices 6a and 6b are designed in several parts. The tension rods 8 each have a tension rod section 34 arranged in the first building part 2. The tension rods 8 also each have an anchor sleeve 33 embedded in the second building part 3. The tension rod sections 34 are screwed into the anchor sleeves 33. Each anchor sleeve 33 has an internal thread 36 into which a threaded section 35 of a tension rod section 34 is screwed. The threaded section 35 of the tension rod sections 34 protrudes in particular from the first building part 2 into the second building part 3. The tension rods 8 of the connecting devices 6c and 6d are designed in particular accordingly.

[0057] The Fig. 14 to 16 show the potting housings 11 of two connecting devices 6a and 6c. The central axes 22 and 24 of the connecting devices 6a and 6c and the central axes 23 and 25 of the connecting devices 6b and 6d, which are shown in Fig. 14 are also shown, are spaced apart by a distance o measured in the vertical direction z. The center axes 22, 23, 24, 25 are each spaced apart by a distance p measured in the vertical direction z from the center axis 26 of the first connecting device 5. The center axes 24 and 25 are arranged lower than the center axis 26. The center axes 22 and 23 are arranged higher than the center axis 26.

[0058] Because the central axes 22, 23, 24, 25, and 26 are not arranged at the same height, but are spaced apart in the vertical direction z, the connecting arrangement 4 can absorb comparatively large moments about an axis aligned in the longitudinal direction x of the joint. This ensures effective transmission of large forces. This arrangement is particularly advantageous for connecting a building ceiling to a wall.

[0059] Two casting housings 11 arranged one above the other are each connected to each other via a connecting section 31. In the exemplary embodiment, the connecting section 31 has approximately the same internal cross-section as the casting housings 11. The lower casting housing 11 of the connecting devices 6b and 6c has a filling channel 32 which has a filling opening 12. The filling opening 12 is arranged in particular on the upper side 15 of the first structural part 2, as Fig. 12 shows.

[0060] How Fig. 15 shows, the upper of the two interconnected casting housings 11 each has a venting channel 13 which has a venting opening 14. The venting opening 14 is arranged in particular on the upper side 15 of the first structural part 2, as Fig. 12. The arrangement of the vent opening 14 and the filling opening 12 is also shown in Fig. 16 shown.

[0061] Fig. Figure 17 shows the design of the tension rod section 34 with the threaded section 35. In particular, the tension rod section 34 is designed with a round cross-section. The tension rod section 34 has a diameter u that corresponds to the width e and the height c of the tension rod 8 of the previous embodiment ( Fig. 2 and Fig. 11). The tension rod section 34 is made in particular of steel, in particular of structural steel.

[0062] The Fig. Figures 18 to 20 show the design of the anchor sleeve 33. The anchor sleeve 33 has an anchoring section 37. On the opposite side, the anchor sleeve 37 has a fastening plate 38 with fastening openings 39. The fastening openings 39 serve for fixing to a formwork during the manufacture of the second structural part 3. The figures also show the internal thread 36 of the anchor sleeve 33.
