Description

[0001] The invention relates to a device for the subsequent force-transmitting connection of a second load-bearing structural component to a first load-bearing structural component, in particular a balcony slab to a building ceiling, and to a structure with such a device.

[0002] German patent application DE 20 2021 000 466 U1 discloses a device for the subsequent thermally insulating, force-transmitting connection of a second load-bearing structural element to a first load-bearing structural element. The device comprises a thermally insulating component that is fixed to the first structural element during its construction. For this purpose, reinforcing elements of the thermally insulating component are cast into the first structural element. The second structural element can then be fixed to the first structural element after both the first and second structural elements have been constructed.

[0003] The present invention is based on the objective of providing a device for the subsequent force-transmitting connection of a second load-bearing structural component to a first load-bearing structural component, which enables the simple manufacture of the structural components. A further objective of the present invention is to provide a structure that can be easily manufactured using such a device.

[0004] This problem is solved with respect to the device for the subsequent force-transmitting connection of a second load-bearing structural element to a first load-bearing structural element by a device having the features of claim 1. With respect to the structure, the problem is solved by a structure having the features of claim 14.

[0005] The device is designed to allow for the subsequent connection of the connecting element to the first structural component and the subsequent connection of the second structural component to the connecting element. "Subsequent" in this context means that the first and second structural components can be manufactured separately from concrete and that the device is designed to allow the structural components to be connected via the connecting element after their manufacture, i.e., after the concrete of the structural components has hardened. Subsequent connection is not possible, for example, if a reinforcing component of the connecting element must be embedded in the concrete of one of the structural components.

[0006] Because the connecting device can be attached to the first structural element after construction, the manufacturing of this element is simplified. The formwork for the structural elements is also simplified, as the connecting device does not need to be positioned and aligned within the formwork. This reduces the complexity of the formwork. The elements of the device to be embedded in the structural elements can be easily positioned on the respective formwork. Positioning can be achieved, in particular, via the connections that will be used to connect the connecting device to the structural element after completion of the respective structural element. If the connections are threaded, the elements of the device to be embedded can be positioned from the outside using screws or nuts inserted through holes in the formwork.

[0007] The transport of the structural components is simplified because the connecting device, which extends beyond the components, only needs to be attached to them after they have been transported to the construction site. In a preferred embodiment, at least one, and in particular both, structural components are precast concrete elements. The connecting device is advantageously attached to the first structural component only after the first component has been installed in the structure. Advantageously, after the connecting device has been attached to the first structural component, it is adjusted relative to the structure, and then the second structural component is attached to and fixed to the connecting device.

[0008] Advantageously, the tensile force-transmitting means, the shear force-transmitting means, and the compressive force-transmitting means of the connecting device are designed separately from one another. This allows for a favorable design and good adaptation to the forces to be transmitted.

[0009] Advantageously, the tensile force-transmitting means of the connecting device can be connected to the tensile force-transmitting means of the first structural element via at least one detachable connection, in particular via at least one screw connection.

[0010] In a preferred embodiment, the pressure-transmitting means of the connecting device have an end face for contact with at least one pressure introduction element of the first structural component. This enables a simple transmission of the pressure forces.

[0011] The shear force transmitting means of the connecting device are advantageously connectable to the shear force transmitting means of the first structural element via at least one detachable connection, in particular via at least one screw connection.

[0012] Instead of at least one screw connection, another type of connection, preferably a detachable connection, may also be provided.

[0013] Advantageously, the shear force-transmitting means of the connection device have at least one shear force section that is at least partially designed for placement in the separation joint. This shear force section is advantageously connectable to at least one anchoring element embedded in the first structural element via a connection that can be subsequently installed. The connection that can be subsequently installed is preferably a bolted connection. However, another type of connection that can be subsequently installed, for example a welded connection, may also be provided.

[0014] Advantageously, the contact surface is formed on a first leg and the bearing surface on a second leg of a support bracket of the connecting device. This results in a simple design of the contact surface and bearing surface. Preferably, the first leg and the second leg of the support bracket are connected by at least one cheek extending transversely to the longitudinal direction. A simple design is achieved if an upper surface of the at least one cheek of the support bracket is extended and forms a shear force section intended for placement in the joint. Particularly preferred are two cheeks arranged at opposite ends of the support bracket, each of which is extended and forms a shear force section intended for placement in the joint.

[0015] Advantageously, the support bracket is made of metal. Particularly preferred is the support bracket, including at least one cheek, formed from sheet metal, especially by punching, bending, and welding.

[0016] It can be provided that the second structural element rests directly on the support bracket with its concrete. For improved force transmission, the system is specifically designed to include a support element, particularly a support bracket, intended for embedding in the second structural element. The support element advantageously has a first support surface for transferring laterally directed compressive forces and a second support surface for transferring vertically directed shear forces to the support bracket. The support element can be in direct contact with the support bracket. The interposition of additional elements between the support element and the support bracket is also possible.

[0017] The device comprises force-transmitting means for transferring tensile forces between the two structural components. Advantageously, these force-transmitting means comprise first and second tension rods. The first tension rods are advantageously designed for embedding in the first structural component, and the second tension rods for embedding in the second structural component. The first and second tension rods advantageously extend substantially or completely along opposite sides of the joint or the connecting device. The first tension rods are advantageously force-transmitting and connected to the second tension rods via tension rod sections of the connecting device. In a particularly preferred embodiment, the longitudinal center axes of the first tension rods, the second tension rods, and the tension rod sections are arranged in a common plane perpendicular to the vertical direction. This enables advantageous force transmission.

[0018] A simple design is achieved when the tension rod sections of the connecting device and the first and / or second tension rods are fixed to one or more common connecting plates for creating the connection. Preferably, the second tension rods and the tension rod sections are fixed to a common connecting plate. The tension rod sections and the first and / or second tension rods can be connected to the at least one connecting plate, for example, by bolted or welded connections.

[0019] The second structure section can be manufactured entirely in the precast plant, and no cast-in-place concrete, injection mortar, or similar materials are required on-site to connect the precast second section to the first. In a preferred design, the second structure section is also manufactured in the precast plant. The first and second structure sections can be manufactured without the connecting device. Only the connection points for the force-transmitting connection to the connecting device need to be provided in the first and second structure sections.

[0020] To achieve effective thermal decoupling of the building components, the connecting device may include insulating material intended for placement within the expansion joint. This insulating material may be a dimensionally stable insulating body. For example, the insulating material could be a foamed material such as foam, mineral foam, or similar. Alternatively, the insulating material, such as mineral wool, may be contained within a housing. The insulating material may be an integral part of the connecting device. Another option is to place the insulating material in the expansion joint after the building components have been joined. Other arrangements of the insulating material and / or different insulating materials may also be advantageous.The structure is designed to comprise a first load-bearing concrete element and a second load-bearing concrete element, as well as a connection device for the second load-bearing element to the first. The connection device is located, at least partially, in a separation joint between the structural elements.

[0021] The parts of the facility embedded in the first part of the building form a first connection facility, and the parts of the facility embedded in the second part of the building form a second connection facility.

[0022] The first and second connection devices preferably terminate flush with the end faces of the associated structural component. This largely prevents damage to the connection devices during transport of the structural components.

[0023] In an alternative design, it may be provided that the parts of the connecting devices intended for connection with the connecting device project beyond the end faces of the building components.

[0024] Exemplary embodiments of the invention are explained below with reference to the drawing.

Figs. 10 and 11 .

[0025] Fig. 1Figure 1 schematically shows a section of a structure 50. The structure 50 comprises a first structural element 2, in this example a building ceiling, and a second structural element 3, in this example a balcony slab. The second structural element 3 is connected to the first structural element 2 via a connecting device 1, thus transmitting forces. The load-bearing structural elements 2 and 3 are made of concrete, in this example of steel-reinforced concrete. The connecting device 1 was attached to the first structural element 2 after its manufacture. The load-bearing structural element 3 was then fixed to the connecting device 1 after its manufacture. This allows the load-bearing structural element 3 to be manufactured to a high standard, for example in a precast concrete plant, and then quickly fixed to the structural element 2 on the construction site, thereby reducing crane times and thus lowering production costs.The first load-bearing structural element 2 can also be advantageously manufactured in the precast concrete plant.

[0026] In the exemplary embodiment, the connecting device 1 comprises insulating material 5, or in the exemplary embodiment, an insulating body, which is arranged in a separation joint 4 between the first building component 2 and the second building component 3. The first building component 2 has a longitudinal side 6 that defines the separation joint 4. The second building component 3 has a longitudinal side 7 that defines the separation joint 4. The insulating material 5 is arranged between the longitudinal sides 6 and 7. In the exemplary embodiment, a narrow gap is formed between the insulating material 5 and the second building component 3. However, it can also be provided that the second building component 3 rests against the insulating material 5.

[0027] The connecting device 1 has a longitudinal direction 28, which is aligned in the longitudinal direction of the expansion joint 4. The longitudinal direction 28 preferably runs horizontally in the installed state. The connecting device 1 has a vertical direction 30, which runs perpendicular to the longitudinal direction 28. The vertical direction 30 preferably runs vertically in the installed state. The connecting device 1 has a transverse direction 29, which, in the installed state, runs from the longitudinal side 6 to the opposite longitudinal side 7. The transverse direction 29 is aligned perpendicular to the longitudinal direction 28 and perpendicular to the vertical direction 30. The transverse direction 29 preferably runs horizontally in the installed state.

[0028] The connecting device 1, together with other elements, forms a device for force-transmitting the second structure section 3 to the first structure section 2. The device consists of three separate units: the connecting device 1, a first connection device 42 comprising force-transmitting means located in the first structure section 2, and a second connection device 43 comprising force-transmitting means located in the second structure section 3. The three units can be connected to each other after completion of the two structure sections 2 and 3. This allows for subsequent connection of the connecting device 1 to the first structure section 2 and subsequent connection of the second structure section 3 to the connecting device 1. The three units are detachably connected to each other. Advantageously, the tensile force-transmitting means of the three units are connected to each other via bolted connections.The compressive force-transmitting elements of the three units advantageously rest against each other for force transmission. For the transverse force-transmitting elements, at least one connection and / or at least one bolted connection can be advantageous for force transmission. The connecting device 1 can consist of several separately designed components. It can also be provided that the connecting device 1 forms a single assembly. This is particularly advantageous if an insulating body is provided to which the components of the connecting device 1 are attached.

[0029] For the transmission of tensile forces between structural components 2 and 3, the device comprises first tension rods 9, which are embedded in the first structural component 2, and second tension rods 10, which are embedded in the second structural component 3. The device also includes tension rod sections 60, which are part of the connecting device 1. In the exemplary embodiment, the tension rod sections 60 extend through the insulating material 5, namely the insulating body 5. The tension rods 9 and 10 are each connected to each other via a force-transmitting tension rod section 60.

[0030] In the exemplary embodiment according to Fig. 1The first tension rods 9 extend to the longitudinal side 6 of the insulating body 5. The tension rods 9 have threaded sleeves 61 at their ends. The threaded sleeves 61 can, for example, be flush with the surface of the first structural component 2. The tension rod sections 60 are screwed into the threaded sleeves 61. For this purpose, the tension rod sections 60 advantageously have an external thread at their end facing the first structural component 2. In the exemplary embodiment, the insulating body 5 is designed as a box, which can advantageously be opened from above so that the tension rod sections 60 and the locknuts 62 provided in the exemplary embodiment are accessible. Alternatively, the tension rod sections can be accessible from the side of the connecting device 1 facing away from the first structural component 2.

[0031] In the exemplary embodiment, the force-transmitting connection of the tension rods 10 with the tension rod sections 60 is provided outside the separation joint 4, in particular outside the insulating body 5. Recesses 15 are provided on a top surface 40 of the second structural part 3, which is located at the top when installed. The ends of the tension rods 9 project into these recesses 15. This makes the ends of the tension rods 9 accessible from the top surface 40. The second tension rods 10 are firmly connected to a connecting plate 11 arranged on the second structural part 3, in the exemplary embodiment by means of welded connections ( Fig. 2The tension rod sections 60 are screwed to the connecting plate 11. For this purpose, a fastening nut 14 is screwed onto each of the tension rod sections 60 in the recesses 15. In the exemplary embodiment, a washer 21 is arranged between each of the fastening nuts 14 and the connecting plate 11. Because the recesses 15 are open to the top 40 of the second structure part 3, the second structure part 3, with the connecting plate 11, can be placed onto the tension rod sections 60 and fixed to the connecting device 1 by tightening the fastening nuts 14. The tension rod sections 60 and the second tension rods 10 project from the connecting plate 11 on opposite sides.

[0032] A support bracket 17 is arranged on the second structural element 2 to transmit compressive and shear forces. Advantageously, the support bracket 17 forms part of the connection device 1. In the exemplary embodiment, the support bracket is captive and held on the insulating body forming the insulating material 5. The support bracket 17 is connected to anchoring elements 16 via a fixed connection that can be established after the first structural element 2 has been erected. The anchoring elements 16 are embedded in the concrete of the first structural element 2 and are thus force-transmittingly connected to the first structural element 2. Each anchoring element 16 has a threaded sleeve 55 at its end facing the joint 4. The support bracket 17 is fixed to the threaded sleeve 55 via shear force sections 56, as will be described in detail below.

[0033] The support bracket 17 is supported horizontally via at least one pressure bearing 41 of the connecting device 1 against at least one pressure element embedded in the first structural element 2, in this embodiment a pressure plate 65. In this embodiment, the pressure plate 65 is connected to the first structural element 2 by an anchoring element 19 embedded in the concrete of the first structural element 2 for fixation. The support bracket 17 is connected to the pressure bearing 41 in this embodiment via a connection that can be established after the second structural element 3 has been manufactured. In this embodiment, a nut 64 is welded to the support bracket 17 for this purpose, into which the rod-shaped pressure bearing 41 is screwed. However, another pressure-transmitting connection may also be advantageous.

[0034] How Fig. 7As shown in the exemplary embodiment, three nuts 64 and three thrust bearings 41 are provided. In this embodiment, the thrust bearings 41 are designed as screws whose screw heads form the end faces 48 and bear against the first structural element 2. For this purpose, a pressure plate 65 is embedded in the first structural element 2, which can be held in the concrete of the first structural element 2 by at least one anchoring element 19. A different design of the elements for introducing compressive forces into the first structural element 2, for example as thrust bearings or the like, may also be advantageous.

[0035] The first tension bars 9 have longitudinal axes 12, and the second tension bars 10 have longitudinal axes 13, as shown in Fig. 2 As depicted. Fig. 1As shown, the first tension bars 9 and the second tension bars 10 are arranged at the same height. The longitudinal axes 12 and 13 lie in a common plane 38, perpendicular to the vertical direction 30. The plane 38 runs parallel to the longitudinal direction 28 and parallel to the transverse direction 29. The tension bars 9 and 10 are arranged offset from each other in the plane 38. Fig. 2 As shown, the longitudinal axes 12 and 13 of adjacent tension bars 9 and 10 have an offset a to each other measured in the longitudinal direction 28. The tension bar sections 60 advantageously have longitudinal center axes 63 which lie in the plane 38 with the longitudinal axes 12 and 13, as shown by the Figs. 1 and 2 show.

[0036] The insulating material 5 has a bottom side 8 which is positioned at the bottom when installed, as Fig. 1 The underside 8 runs approximately in a plane with an underside 45 of the support angle 17 and an underside 46 of the second structural part 3.

[0037] The device comprises three units that can be connected to one another after the construction of structural components 2 and 3: the first connection device 42, the connecting device 1, and the second connection device 43. The first connection device 42 is embedded in the concrete of the first structural component 2, and the second connection device 43 is embedded in the concrete of the second structural component 3. During the construction of structural components 2 and 3, the connection devices 42 and 43 are permanently and inseparably connected to their respective components. In the exemplary embodiment, the first connecting device 42 is flush with the longitudinal side 6 of the first building section 2 and does not project beyond the longitudinal side 6 of the first building section 2 into the separation joint 4. In the exemplary embodiment, the second connecting device 43 is flush with the longitudinal side 7 of the second building section 3 and does not project beyond the longitudinal side 7 of the second building section 3 into the separation joint 4.

[0038] The first connection device 42 comprises at least one tension rod 9, at least one anchoring element 16, and at least one compression plate 65 with the anchoring element 19. The elements 9, 16, and 19 can be designed with or without an anchor head. Other means for introducing forces to be transferred into the first structural element 2 may also be advantageous.

[0039] The connecting device 1 comprises at least one tension rod section 60 and the support angle 17 with at least one pressure bearing 41 fixed to it and at least one shear force section 56.

[0040] The second connecting device 43 comprises at least one second tension rod 10, at least one second compression rod 20, and at least one in Fig. 3The support angle 31 shown. The bars 10 and 20 can be designed with or without an anchor head. Other means of introducing forces to be transferred into the second structural element 3 may also be advantageous.

[0041] Fig. 3 Figure 1 shows the device in detail, although the structural components 2 and 3 and the insulation material 5 are not shown. The support bracket 17 of the connecting device 1 has two legs 24 and 25, which in the exemplary embodiment are aligned at right angles to each other. The legs 24 and 25 run parallel to the longitudinal direction 28 of the connecting device 1. The first leg 24 runs parallel to the vertical direction 30 of the connecting device 1 ( Fig. 1The first leg 24 is advantageously vertically aligned on the structure 50 when installed. The first leg 24 forms a contact surface 22 on the side facing away from the first structure part 2 for the transmission of compressive forces. The second leg 25 runs parallel to the transverse direction 29 of the connecting device 1 ( Fig. 1 ) and is advantageously horizontally oriented in the installed state. On the second leg 25, a bearing surface 23 for transmitting shear forces is formed on the side facing upwards in the installed state.

[0042] How Fig. 4 As shown, the second leg 25 of the support bracket 17 runs at approximately the same height as the underside 8 of the insulating material 5. On the bearing surface 23 ( Fig. 3 ) the second building component 3 can be placed on top and then fixed to the connecting device 1.

[0043] Both Figs. 4 to 7These are schematic drawings in which hidden, invisible edges are also represented with a solid line.

[0044] The two legs 24 and 25 are connected to each other via at least one cheek 18, in the exemplary embodiment via two cheeks 18, as Fig. 3 and Fig. 6 show. The cheeks 18 extend perpendicular to the longitudinal direction 28 ( Fig. 3 In the exemplary embodiment, the cheeks 18 are arranged at the two ends of the legs 24 and 25, which are arranged in the longitudinal direction 28. The at least one cheek 18 advantageously has an approximately triangular shape. The cheek 18 has a top surface 51 ( Fig. 4), which connects the legs 24 and 25. Preferably, the upper surface 51 extends in a straight line over at least part of its length. The upper surface 51 of the cheek 18 advantageously extends in the viewing direction of the longitudinal axis 28 inclined to the transverse direction 29, preferably at an angle α of 30° to 60°. At the upper surface 51, the cheeks 18 are extended into the separation joint 4 and form a shear force section 56, as Fig. 4 shows. The shear section 56 is advantageously designed as a strut, the height e of which ( Fig. 5 ) greater than the width f measured in the longitudinal direction 28 ( Fig. 6The height e is measured perpendicular to the longitudinal direction of the shear force section 56. The shear force section 56 advantageously runs in a straight extension of the upper surface 51. The shear force section 56 advantageously runs inclined in the viewing direction of the longitudinal direction 28 to the transverse direction 29, preferably at an angle of 30° to 60°. The shear force section 56 forms a diagonal brace which, in the installed state, runs at least partially within the joint 4.

[0045] In the illustrated embodiment, the support bracket 17 is arranged outside the separation joint 4. The support bracket 17 projects into the area of ​​the second structure section 3. On the side of the first leg 24 facing the second structure section 2, the thrust bearings 41 are fixed to the first leg 24.

[0046] Advantageously, the support bracket 17 is made of metal. The support bracket 17, including at least one cheek 18 and at least one shear section 56, is formed from sheet metal, preferably from at least two interconnected sheet metal parts. The sheet metal parts of the support bracket 17 are preferably connected to each other by welded joints.

[0047] How Figs. 4, 6 and 7 As shown, the ends of the shear sections 56 are fixed to a common connecting web 57, in particular by means of welded connections. The connecting web 57 is fixed to the first structural section 2 by means of fastening screws 58, which are screwed into the threaded sleeves 55 of the anchoring elements 16. The anchoring elements 16 are embedded in the first structural section 2, as shown. Fig. 1This shows that shear forces are transferred from the bearing angle 17 to the first structural element 2 via the shear force sections 56. The shear force sections 56, together with the anchoring elements 16, the connecting web 57, and the fastening screws 58, form shear force elements.

[0048] The fastening screws 58 form a subsequently manufactured, detachable connection between the support bracket 17 and the first structural element 2 with the threaded sleeves 55.

[0049] The first leg 24 of the support bracket 17 has a rear side 54 facing away from the second leg 25. In the exemplary embodiment, the nut 64 is fixed to the rear side 54, into which the thrust bearing 41, preferably a screw, is screwed. The nut 64 forms a subsequently created, detachable connection with the thrust bearing 41. The nut 64 can, for example, be screwed onto the support bracket 17.

For tensile force transmission, the second tension rods 10 and the connecting plate 11 connected to the second tension rods 10 are provided in the second structural section 3. A support bracket 31 is provided for the transmission of compressive and shear forces. Instead of the support bracket 31 provided in the exemplary embodiment, other types of support elements can also be provided for the transmission of horizontal compressive forces and vertically directed shear forces. Compression rods 20 are fixed to the support bracket 31. The compression rods 20 are embedded in the second structural section 3 and are advantageously designed as straight rods. A different design of the compression rods 20 may also be advantageous. The support bracket 31 has a first support surface 32, which is vertically oriented in the installed state and serves to transmit horizontally directed compressive forces.The support bracket 31 also has a second support surface 33. In the exemplary embodiment, the second support surface 33 is oriented perpendicular to the first support surface 32. Advantageously, the second support surface 33 runs parallel to the underside 46 of the second structural element 3 and parallel to the longitudinal axis 13 of the tension rods 10. Fig. 8 ).

[0051] In the exemplary embodiment, the support bracket 31 rests against a formwork body 34. The formwork body 34 is preferably designed for arrangement on a formwork for the production of the second building component 3 and abuts the underside 46 and the longitudinal side 7 of the second building component 3.

[0052] How Fig. 9 As shown, two compression rods 20 are fixed to the support bracket 31 in the exemplary embodiment. The support bracket 31 has a length b that is parallel to the longitudinal direction 28 of the connecting device 1 ( Fig. 1) is measured. The length b is measured horizontally in the installed state. Figures 10 to 12 The support bracket 31 and the formwork body 34 are shown in detail. The formwork body 34 has a [feature] on its side facing the concrete of the second structure section 3. Fig. 12 The illustrated recess 47 provides a space for the support bracket 31. In this embodiment, the recess 47 is bounded by two cutouts 37 located on the opposite side of the formwork body 34. The two cutouts 37 are spaced c apart from each other, which is greater than the length b of the support bracket 31, allowing the support bracket 31 to be positioned between the two cutouts 37. The formwork body 34 is preferably an injection-molded plastic part.

[0053] How Fig. 11As shown, the formwork body has a first surface 35 which is intended for contact with the contact surface 22 of the support angle 17 and serves to transmit horizontally acting compressive forces. Fig. 8 As shown, the formwork body 34 has a second surface 36 which is designed to rest against the support surface 23 and serves to transfer shear forces.

[0054] The recesses 37 each have a width d. The width d of the recesses 37 is selected such that a cheek 18 can be positioned in the recess 37. The length b of the support bracket 31 is preferably only slightly less than the distance c between the recesses 37.

[0055] In an alternative embodiment, both the tension rods 10 and the tension rod sections 60 can be fixed to the connecting plate 11 by means of fastening nuts 14. In the exemplary embodiment, a washer 21 is arranged between each fastening nut 14 and the connecting plate 11. However, the washers 21 can also be omitted.

[0056] Instead of the pressure plate 65 shown in the embodiment for introducing the pressure force into the first structural element 2, other means for introducing the pressure force, for example compression rods or compression bearings, can also be provided.

[0057] In an alternative design, the support angle 17 can be arranged in the separation joint 4, preferably in a corresponding recess of the insulating material 5.
