Description

Technical Field

[0001] The present invention relates to a device for an additional thermally insulating, force-transmitting connection for a load-bearing second building member to a load-bearing first building member (the second building member and the first building member, in particular, roof slabs and balcony slabs), and to a building with such a device. Background Technology

[0002] A structural element for connecting two reinforced concrete members is disclosed in DE 10 2005 012 862 A1. An angle steel is provided, supporting one of the reinforced concrete members, such that a connecting device engages the reinforced concrete member from below. Shear bars are fastened to the angle steel. Inclined extensions of the shear bars are arranged in expansion joints (or expansion joints, or Dehnfuges) between the structural members. The shear bars extend through openings in the rear wall of the angle steel and are fastened to the support plate of the angle steel. This results in a relatively complex structure for the connecting device. Summary of the Invention

[0003] The object of this invention is to provide a device for an additional thermally insulating, force-transmitting connection between a load-bearing second structural member and a load-bearing first structural member, having a simple structure and achieving advantageous shear force transmission. Another object of this invention is to describe an advantageous building with such a device.

[0004] Regarding the additional thermally insulating, force-transmitting connection device for the load-bearing second structural member to the load-bearing first structural member, this objective is achieved by a device for the additional thermally insulating, force-transmitting connection device for the load-bearing second structural member to the load-bearing first structural member, wherein the device has an insulator for being arranged in a trench between the first and second structural members, as well as a tension transmission device, a pressure transmission device, and a shear transmission device, wherein the insulator has a first longitudinal side and an opposing second longitudinal side provided for being arranged at the first structural member, wherein the insulator has a longitudinal direction, a transverse direction perpendicular to the longitudinal direction and extending from the first longitudinal side to the second longitudinal side, and a height direction perpendicular to the longitudinal direction and extending perpendicular to the transverse direction, wherein the pressure transmission device includes a connection from the second... The device includes a longitudinally accessible analgeflache for bearing horizontal pressure on the second building member and at least one pressure element extending at least to the first longitudinal side and connected to the analgeflache for force transmission. The shear force transmission device includes a support surface accessible from the second longitudinal side for bearing vertically directed forces on the second building member and at least one shear bar connected to the support surface for force transmission. The analgeflache is constructed at the first leg of the support angle steel, and the support surface is constructed at the second leg of the support angle steel. The first and second legs of the support angle steel are connected via at least one sidewall arranged transversely to the longitudinal direction. The shear bar has an inclined section extending in the height direction, and at least one shear bar is directly fastened to the sidewall with its inclined extended section.

[0005] Regarding this building, the objective is achieved through a building comprising a load-bearing first building member and a load-bearing second building member (parts one and two, particularly a roof slab and a balcony slab) made of concrete, and a device for an additional thermally insulating, force-transmitting connection between the load-bearing second building member and the load-bearing first building member (particularly the balcony slab at the roof slab). This device includes an insulator for arrangement in a gap between the first and second building members, as well as tensile force transmitting devices, compressive force transmitting devices, and shear force transmitting devices. The insulator has a first longitudinal side and an opposing second longitudinal side disposed at the first building member. The insulator has a longitudinal direction, a transverse direction perpendicular to the longitudinal direction and extending from the first longitudinal side to the second longitudinal side, and a height direction perpendicular to both the longitudinal and transverse directions. The compressive force transmitting device includes a contact surface accessible from the second longitudinal side for bearing the horizontal pressure of the second building member and at least extending vertically... At least one pressure element is connected to the abutment surface on the first longitudinal side for force transmission, wherein the shear force transmission device includes a support surface accessible from the second longitudinal side for bearing vertically directed forces of the second building member and at least one shear bar connected to the support surface for force transmission, wherein the abutment surface is constructed at the first leg of the supporting angle steel and the support surface is constructed at the second leg of the supporting angle steel, wherein the first leg and the second leg of the supporting angle steel are connected via at least one sidewall arranged transversely to the longitudinal direction, wherein the shear bar has an inclined section extending in the height direction, wherein at least one shear bar is directly fastened to the sidewall with its inclined extended section, wherein an insulator is arranged in the separation joint between the first building member and the second building member, wherein the first longitudinal side of the insulator is arranged at the first building member, wherein the second building member is supported at the abutment surface and the support surface is supported relative to the first building member, and wherein the section of the shear bar protruding into the first building member beyond the insulator is embedded in the concrete of the first building member.

[0006] The support angle steel is configured to transmit pressure and shear forces, having a contact surface for transmitting pressure and a support surface for bearing vertical shear forces. The additional assembly of the second structural member can be easily achieved by placing it onto the support angle steel, thereby transmitting pressure and shear forces via the support and contact surfaces. To achieve effective shear force introduction, the two legs of the support angle steel are connected via at least one sidewall arranged transversely to the longitudinal direction of the insulator. Shear bars are directly fastened to the sidewall with their inclined sections extending in the height direction. The shear bars thus extend beyond the contact surface in the direction of the second structural member. This allows for the introduction of shear force with a relatively large spacing relative to the first structural member. Simultaneously, the fastening of the shear bars to the sidewall provides a simple and stable fastening solution. The sidewall also stabilizes the angle steel and fixes the position of the second structural member relative to the first structural member in the longitudinal direction of the insulator. Here, the sidewall does not need to extend into the wedge-shaped support for the angle steel, where the two legs supporting the angle steel abut against each other; instead, it can be left open in the area of ​​the wedge-shaped support. When the second building component is assembled as a prefabricated part into the first building component, its positioning within the first building component can be achieved in a simple manner.

[0007] The device is constructed such that it enables an additional connection between the second building component and the first building component. "Additional" in this sense means that the first and second building components can be manufactured separately from each other, particularly from concrete, and the device is designed so that it is feasible for the building components to be connected to each other after their manufacture, i.e., especially after the concrete of the building components has hardened. An additional connection would not be feasible, for example, if reinforcements had to be embedded in the concrete of both building components.

[0008] It has been shown that, for good force introduction, it is advantageous to minimize the distance between the ends of the inclined extension sections of the shear bar opposite to the first longitudinal side and the bottom side of the insulator. Thus, force can be introduced, for example, at the height of the bottom side of the insulator. Typically, the bottom side of the second building member is arranged, for example, at the height of the bottom side of the insulator, so that force introduction can be achieved based on the illustrated arrangement structure near the bottom side of the second building member. Preferably, the distance between the ends of the inclined extension sections of the shear bar arranged at the sidewall and the bottom side of the insulator, measured along the height direction, is less than 5 cm, especially less than 2 cm. The other end of the inclined extension section is advantageously arranged at the insulator, or the inclined extension section extends completely through the insulator. Especially in the case of relatively tall insulators, the distance between the ends of the inclined extension sections of the shear bar and the bottom side of the insulator can also be constructed to be larger. Advantageously, the distance between the ends of the sections of the shear bar arranged at the sidewall and the bottom side of the insulator is at most one-quarter of the height of the insulator.

[0009] The inclined extension sections of the shear bars, located on the sidewall opposite to the first longitudinal side, are preferably positioned relative to the first structural member at the largest possible distance to facilitate advantageous force introduction. The inclined extension sections of the shear bars, located on the sidewall opposite to the first longitudinal side, advantageously have a transversely measured distance relative to the insulator, which is at least 2 cm, and particularly at least 5 cm. The inclined extension sections of the shear bars, located on the sidewall opposite to the first longitudinal side, advantageously have a transversely measured distance relative to the back side of the first leg opposite to the second leg, which is at least 2 cm, and particularly at least 5 cm. In the case where the supporting angle steel is arranged on the second longitudinal side of the insulator, the distance relative to the insulator corresponds to the distance relative to the back side of the first leg.

[0010] Advantageously, the distance measured along the height direction between the end of the inclined extension section of the shear bar opposite to the first longitudinal side and the bottom side of the insulator is less than the distance measured along the transverse direction between that end and the insulator. Preferably, the distance measured along the height direction between that end and the bottom side of the insulator is less than 80%, and particularly less than 50%, of the distance measured along the transverse direction between that end and the insulator.

[0011] In a particularly advantageous design, the inclined extension section of the shear bar is welded to the sidewall. However, other forms of fixing are also possible.

[0012] An advantageous design is achieved by arranging the two sidewalls at opposite ends of the supporting angle steel, where shear bars are tightly fastened. This results in a good distribution of the introduced shear force to the two shear bars and a symmetrical force introduction.

[0013] Advantageously, the supporting angle steel is made of metal. Particularly preferably, the supporting angle steel, including at least one sidewall, is formed from sheet metal, especially by punching, bending, and welding.

[0014] In a preferred embodiment, the supporting angle steel extends beyond the insulator towards the second structural member. In the longitudinal direction of view, the supporting angle steel advantageously overlaps the insulator to the greatest extent possible. Particularly preferably, the supporting angle steel does not overlap the insulator in the longitudinal direction of view. In an alternative advantageous design, however, the insulator may have a gap in which the supporting angle steel is partially or completely arranged. This is particularly advantageous if a relatively wide expansion joint can be bridging it.

[0015] The second building member can be configured such that its concrete is directly supported on a supporting angle steel. To improve force introduction, the device is specifically configured to include a support member, particularly a supporting angle steel, which is arranged to be embedded in the second building member. The support member advantageously has a first supporting surface for transmitting transversely oriented pressure relative to the supporting angle steel, and a second supporting surface for transmitting vertically oriented shear force relative to the supporting angle steel. Here, the support member can be directly abutted against the supporting angle steel. However, an additional element can also be positioned intermediately between the support member and the supporting angle steel.

[0016] To achieve good force transfer between the support member and the second building member, at least one reinforcing element is advantageously fastened at the support member. This reinforcing element is preferably at least one compression bar embedded in the concrete of the second building member.

[0017] To facilitate the placement of the second building member onto the supporting angle steel, it is advantageously configured that the second building member has openings in the sidewalls for supporting the angle steel. To allow for the simple manufacture of these openings, the device is advantageously configured to include a formwork body (Schalungskoerper) having at least one opening for accommodating at least one sidewall and a section thereon where a shear bar is arranged. The formwork body is preferably configured to remain within the second building member. However, it can also be configured that the formwork body is removed from the second building member before it is connected to the first building member.

[0018] The formwork body advantageously has a first surface for support at the abutment surface and a second surface for support at the bearing surface. Support members, particularly supporting angle steels, are advantageously supported at the formwork body, thereby enabling force transfer between building components from the support members through the formwork body to the supporting angle steels. If the formwork body has two openings, it is advantageously arranged such that the length of the support member, measured along the longitudinal direction of the insulator, is less than the distance between the two openings in the formwork body. Thus, the support member can be well positioned at the formwork body. Particularly preferably, the length of the support member, measured along the longitudinal direction of the insulator, is at most 1 cm less than the distance between the two openings in the formwork body. The length of the support member advantageously corresponds to the distance between the two openings minus twice the wall thickness of the formwork body.

[0019] The device includes a force-transmitting device for transmitting tension between two building components. Advantageously, the force-transmitting device includes a first tie rod and a second tie rod. Here, the first tie rod is advantageously configured to be embedded in the first building component, and the second tie rod is configured to be embedded in the second building component. The first and second tie rods advantageously extend generally on opposite sides of the insulator. Advantageously, either the first or second tie rod extends through the insulator. The first tie rod is advantageously force-transmittingly connected to the second tie rod. The force-transmitting connection between the tie rods is advantageously arranged outside the insulator. In a particularly preferred design, the first and second tie rods are arranged in a common plane extending perpendicular to the height direction. This achieves advantageous force transmission.

[0020] A simple design is achieved when the first and second tie rods are fastened to a common connecting plate. The first and second tie rods can be connected to the connecting plate, for example, via threaded connections or welded connections. Preferably, at least the connection between the first tie rod and the connecting plate, or the connection between the second tie rod and the connecting plate, can be loosened, allowing the additional connection from the second building component to the first building component to be achieved simply by placing the second building component and establishing the threaded connection. The second building component can be entirely manufactured in a prefabrication plant, eliminating the need for on-site pouring of concrete, injection mortar, etc., to connect the finished second building component to the first building component.

[0021] The building is configured to have a first load-bearing structural member made of concrete and a second load-bearing structural member made of concrete, and a device for connecting the second load-bearing structural member to the first load-bearing structural member. An insulator of this device is arranged in a gap between the first and second structural members. A first longitudinal side of the insulator is located on the first structural member. The second structural member is supported at an abutment surface, while the support surface of the supporting angle steel is supported relative to the first structural member. A section of the shear bar extending beyond the insulator into the first structural member is embedded in the concrete of the first structural member. The building is advantageously manufactured in such a manner that the second structural member is manufactured in a prefabrication plant, positioned on the construction site, and fastened to the first structural member solely by the connection of first and second tension-transmitting elements.

[0022] Advantageously, the supporting angle steel does not overlap with the insulator in the case of viewing along the longitudinal direction of the insulator. The second building member advantageously has at least one opening relative to the bottom side and the end side of the second building member, into which at least one sidewall of the supporting angle steel extends.

[0023] Advantageously, a first tie rod is embedded in a first building member and a second tie rod is embedded in a second building member, these tie rods being connected to each other at a connecting plate arranged at one of the building members. The building member with the connecting plate advantageously has a recess adjacent to the connecting plate, in which a tie rod extending from the other building member through the insulator and the connecting plate is screwed on. Here, the recess is preferably arranged on the side of the connecting plate opposite to the other building member, so that the tie rod can be secured to the connecting plate by a nut placed in the recess and screwed onto the tie rod. This results in a simple structure.

[0024] The tie rod of this device is preferably not connected to the pressure transmission device and the shear force transmission device, but is arranged separately from them. Therefore, the height of the device can be easily adapted in a simple manner by selecting an insulator with the desired height or by assembling multiple components with an insulator until the corresponding desired height is achieved, without the need for further modifications to the force transmission components. This results in a simple and modular structure for the device. Attached Figure Description

Detailed Implementation

[0026] Figure 1A section of building 50 is schematically shown. Building 50 has a first building member 2 (a roof slab in this embodiment) and a second building member 3 (a balcony slab in this embodiment). The second building member 3 is thermally and force-transmittingly connected to the first building member 2 via a thermally insulated structural element 1. The load-bearing building members 2 and 3 are constructed of concrete, specifically reinforced concrete in this embodiment. The load-bearing building member 3 is fastened to the load-bearing first building member 2 after its manufacture. Thus, the load-bearing building member 3 can be manufactured to high quality, for example, in a prefabrication plant and fastened to the building member 2 very quickly on the construction site, thereby reducing crane time and manufacturing costs.

[0027] The thermally insulating structural element 1 includes an insulator 5 disposed in a gap 4 between a first building member 2 and a second building member 3. The insulator 5 has a first longitudinal side 6 disposed at the first building member 2. An opposing second longitudinal side 7 extends adjacent to the second building member 3. In this embodiment, a narrow gap is formed between the insulator 5 and the second building member 3. However, it is also possible to arrange the second building member 3 abutting against the insulator 5.

[0028] The insulator 5 has a longitudinal direction 28, which is oriented along the longitudinal direction of the expansion joint 4. The longitudinal direction 28 is preferably horizontally extended in the installed state. The insulator 5 has a height direction 30, which extends perpendicularly to the longitudinal direction 28. The height direction 30 is preferably vertically extended in the installed state. The insulator 5 has a transverse direction 29, which extends from the first longitudinal side 6 to the opposite longitudinal side 7. The transverse direction 29 is oriented perpendicularly to the longitudinal direction 28 and perpendicularly to the height direction 30. The transverse direction 29 is preferably horizontally extended in the installed state.

[0029] The thermally insulating structural element 1, together with other elements, forms a device for force-transmittingly connecting the second building member 3 to the first building member 2. This device consists of the thermally insulating structural element 1 fastened to the first building member 2 and other force-transmitting devices arranged on the second building member 3. The force-transmitting devices arranged on the second building member 3 are advantageously releasably connected to the force-transmitting devices arranged on the first building member 2. This allows for an additional connection of the second building member 3 to the first building member 2.

[0030] To transmit tensile force between building components 2 and 3, the device includes a first tie rod 9 embedded in the first building component 2 and a second tie rod 10 embedded in the second building component 3. Tie rods 9 and 10 are force-transmittingly connected to each other. Here, the force-transmitting connection between tie rods 9 and 10 is located outside the insulator 5 in this embodiment. According to... Figure 1In this embodiment, the pull rod 9 extends through the insulator 5. A gap 15 is provided at the top side 40 of the second building member 3. The pull rod 9 extends its end into these gaps 15. Thus, the end of the pull rod 9 can be accessed from the top side 40. The second pull rod 10 is securely connected to the connecting plate 11 arranged at the second building member 3, in this embodiment via welding. Figure 2 The first pull rod 9 is tightened onto the connecting plate 11. For this purpose, a fixing nut 14 is correspondingly tightened onto the pull rod 9 in the opening 15. In this embodiment, a scheibe 21 is arranged between the fixing nut 14 and the connecting plate 11. By opening the opening 15 relative to the top side of the second building member 3, the second building member 3 and the connecting plate 11 can be placed onto the pull rod 9 and forcefully fastened to the first building member 2 by the tightening of the fixing nut 14. The first pull rod 9 and the second pull rod 10 extend away from the connecting plate 11 on their opposite sides.

[0031] To transmit pressure and shear forces, a support angle steel 17 is arranged at the second structural member 2. The support angle steel 17 advantageously forms part of a thermally insulating structural element and is particularly permanently held at the insulator 5. The support angle steel 17 is securely connected to a shear bar 16. The shear bar 16 is embedded in the concrete of the first structural member 2 and is thus force-transmittingly connected to the first structural member 2. The support angle steel 17 is horizontally supported at at least one compression bar embedded in the first structural member 2. It can be configured such that the support angle steel 17 is securely connected to at least one compression bar.

[0032] The first pull rod 9 has a longitudinal axis 12, while the second pull rod 10 has a longitudinal axis 13, as shown in... Figure 2 As shown in the diagram. Figure 1 As shown, the first tie rod 9 and the second tie rod 10 are arranged at the same height. The longitudinal axes 12 and 13 lie in a common horizontally extending plane 38. Plane 38 extends parallel to the longitudinal direction 28 and parallel to the transverse direction 29. Plane 38 extends perpendicular to the height direction 30. Tie rods 9 and 10 are arranged offset from each other in plane 38. Figure 2 As shown, the longitudinal axes 12 and 13 of adjacent tie rods 9 and 10 have an offset a measured along the longitudinal direction 28.

[0033] Insulator 5 has a bottom side 8, which is arranged at the bottom in the installed state, such as Figure 1 As shown, the bottom side 8 extends in a plane approximately in relation to the bottom side 45 of the supporting angle steel 17 and the bottom side 46 of the second building member 3.

[0034] Figures 3 to 6The thermally insulating structural element 1 at the first building member 2 is shown in detail. The supporting angle steel 17 of the thermally insulating structural element 1 has two legs, which are oriented perpendicularly to each other in this embodiment. The legs extend parallel to the longitudinal direction 28 of the insulator 5. The first leg 24 extends parallel to the height direction 30. The first leg 24 is advantageously vertically oriented at the building 50 in the installed state. The first leg 24 forms a pressure-transmitting contact surface 22 on its side facing away from the insulator 5. The second leg 25 extends parallel to the transverse direction 29 and is advantageously horizontally oriented in the installed state. At the second leg 25, the shear force-transmitting support surface 23 is constructed on the upward-pointing side in the installed state. Figure 5 and Figure 6 As also shown, the second leg 25 supporting the angle steel 17 extends near the bottom side 8 of the insulator 5. The second building member 3 can be placed on the support surface 23 and then fastened to the first building member 2.

[0035] Shear bars 16 are embedded in the first structural member 2 and have sections 26 extending at an inclination 30 in the height direction and at an inclination 29 in the lateral direction. In the installed state, the inclined sections 26 descend from the first structural member 2 toward the second structural member 3. The inclined sections 26 of the two shear bars 16 extend at opposite outer sides of the sidewalls 18. Each inclined section 26 is directly fastened to the sidewalls 18, in this embodiment by welding. At least one inclined section 26 of the shear bar 16 extends through the insulator 5.

[0036] Two legs are connected to each other via at least one sidewall 18 (in this embodiment, via two sidewalls 18). The sidewalls 18 extend perpendicular to the longitudinal direction 28. In this embodiment, the sidewalls 18 are arranged at the ends of the legs along the longitudinal direction 28. The at least one sidewall 18 advantageously has an approximately triangular shape. The sidewall 18 has a top side 51 that connects to the legs. Preferably, the top side 51 extends in a straight line for at least a portion of its length. The top side 51 of the sidewall 18 advantageously extends obliquely in the transverse direction 29 along the viewing direction of the longitudinal axis 28 (preferably at an angle of 30º to 60º). The oblique angle of the top side 51 of the sidewall 18 advantageously corresponds to the oblique angle of the oblique section 26 of the shear bar 16.

[0037] In this embodiment, the support angle steel 17 is arranged outside the insulator 5, more specifically on the longitudinal side 7 of the insulator opposite to the first longitudinal side 6. The support angle steel 17 thus extends into the region of the second structural member 3. A first pressure bar 19 is fastened to the first leg 24 on the side facing the insulator 5. The pressure bar is constructed as a relatively long, straight rod, which is embedded in the concrete of the first structural member 2 for pressure transmission. The pressure bar can be screwed, welded, or otherwise fixed to the support angle steel 17.

[0038] like Figures 3 to 6 As also shown, the straight sections of shear bar 16 and tie bar 9 extend at approximately the same height in the first structural member 2. This also... Figure 1 As can be seen in the text.

[0039] The design scheme for supporting angle steel 17 and the reinforcing elements arranged therein, namely two shear bars 16 and two compression bars, is also included. Figures 7 to 9 The details are shown in the diagram. Advantageously, the supporting angle steel 17 is made of metal. The supporting angle steel 17 particularly includes at least one sidewall 18 formed of sheet metal, preferably of at least two sheet metal members connected to each other.

[0040] like Figure 10 As shown, the inclined extension segment 26 has an end 39. End 39 is the end of the inclined extension segment 26 arranged closer to the second longitudinal side 7 of the insulator 5 than to the first longitudinal side 6. The other end of the inclined extension segment 26 is connected to the straight section of the shear bar 16 to be embedded in the first building member 2, as shown. Figures 3 to 6 As shown, the end 39 has a distance f relative to the bottom side 8 of the insulator 5, measured along the height direction 30. The distance f is preferably small. Advantageously, the distance f is less than 5 cm, especially less than 2 cm. The insulator 5 has a height n measured along the height direction. Advantageously, the distance f is at most one-quarter of the height n.

[0041] The first leg 24 of the supporting angle steel 17 has a back side 54 facing away from the second leg 25. In this embodiment, at least one pressure bar is fixed at the back side 54. In this embodiment, the end 39 has a distance g relative to the back side 54 measured in the transverse direction 29. The distance g is advantageously relatively large. Advantageously, the distance g is greater than 2 cm, preferably greater than 5 cm. Preferably, the distance f is less than 80% of the distance g, especially less than 50%. The distance g relative to the back side 54 corresponds to the distance of the end 39 relative to the insulator 5 if the supporting angle steel 17 is arranged with its back side 54 at the second longitudinal side 7 of the insulator 5.

[0042] like Figure 11 As shown, the inclined, extended section 26 is welded to the sidewall 18. Section 26 is connected to the sidewall 18 via weld 27. Figure 11 As also shown, the sidewall 18 and the leg 25 are formed from a single sheet metal piece, which is bent from the plane of the leg 25 at the opposite sides to form the sidewall 18. The first leg 24 is advantageously constructed as a separate plate and by means of... Figure 12 The weld 44 shown is connected to the side wall 18 and the leg 25.

[0043] like Figure 12 As shown, the supporting angle steel 17 has a 30° angle along the height direction. Figure 10 The height h is measured. The sidewall 18 advantageously extends along the entire height direction 30 of the supporting angle steel 17 at the height h measured in the height direction. The region of the section 26 extending at the sidewall 18 extends over a relatively large portion of the height h of the supporting angle steel 17. The inclined extending section 26 extends along the sidewall 18 at a height i, which is advantageously at least 50%, especially at least 70%, of the height h. The free end 39 has a spacing k relative to the bottom side 45 of the supporting angle steel 17 in this embodiment. However, it can also be configured such that the end 39 extends to the bottom side 45. Advantageously, the spacing k is less than 2 cm. Preferably, the spacing k is less than 30%, especially less than 20%, of the height h.

[0044] Figure 13 and Figure 14 The second structural member 3 is schematically shown, with elements arranged thereon for force transmission. For force transmission, a second tie rod 10 and a connecting plate 11 connected to the second tie rod 10 are provided in the second structural member 3. A support angle steel 31 is provided for transmitting pressure and shear force. Alternatively to the support angle steel 31 provided in this embodiment, other forms of support members may be provided for transmitting horizontal pressure and vertical shear force. A second pressure bar 20 is fastened to the support angle steel 31. The second pressure bar 20 is embedded in the second structural member 3 and is advantageously constructed as a straight bar. Other designs of the second pressure bar 20 may also be advantageous. The support angle steel 31 has a first support surface 32, which is vertically oriented in the installed state and is used to transmit horizontal pressure. The support angle steel 31 also has a second support surface 33. In this embodiment, the second support surface 33 is oriented perpendicular to the first support surface 32. The second support surface 33 is advantageously parallel to the bottom side 46 of the second structural member 3 and parallel to the tie rod 10. Figure 13 The longitudinal axis 13 extends.

[0045] In this embodiment, the supporting angle steel 31 abuts against the template body 34. The template body 34 is preferably configured to be positioned at the template for manufacturing the second building component 3 and connected to the bottom side 46 of the second building component 3, as well as to the insulator 5 facing the second building component 3 in the installed state. Figure 1 49 locations on the end side.

[0046] like Figure 14 As shown, in this embodiment, two second pressure bars 20 are fastened to the supporting angle steel 31. The supporting angle steel 31 has a length b, which is parallel to the insulator ( Figure 1 The length b is measured in the longitudinal direction. The length b is measured in the horizontal direction in the installed state. Figures 15 to 17 The supporting angle steel 31 and the formwork body 34 are shown in detail. The formwork body 34 has a concrete side facing the second building member 3. Figure 17The shown receiving portion 47 allows for the arrangement of a support angle steel 31. In this embodiment, the receiving portion 47 is limited by two recesses 37 arranged on opposite sides of the template body 34. These two recesses 37 are spaced apart by a distance c, which is greater than the length b of the support angle steel 31, thereby allowing the support angle steel 31 to be positioned between the two recesses 37. The template body 34 is preferably an injection-molded part made of plastic.

[0047] like Figure 16 As shown, the template body has a first surface 35, which is configured to abut against the abutment surface 22 of the supporting angle steel 17 and to transmit the pressure of horizontal extension. Figure 13 As shown, the template body 34 has a second surface 36, which is configured to rest against the support surface 23 and to transfer shear force.

[0048] The clearance 37 accordingly has a width d. The width d of the clearance 37 is chosen such that the inclined extension section 26 of the side wall 18 and shear bar 16, where they are arranged, can be positioned within the clearance 37. This width d is chosen to ensure good positioning even within common architectural tolerances. Figure 11 As shown, the inclined extensions 26 where the sidewalls 18 and shear bars 16 are arranged have a total width e. The width d of each recess 37 is greater than the total width e. Preferably, the width d is only slightly greater than the total width e of the sidewalls 18 and the inclined extensions 26, so that the formwork body 34 causes the second building member 3 to be positioned at the thermal insulation element 1. The length b of the supporting angle steel 31 is preferably only slightly less than the spacing c between the recesses 37.

[0049] Figure 18 and Figure 19 This illustrates a variant in which the devices for shear force transmission and pressure transmission are constructed according to a previous embodiment. Figure 18 and Figure 19 The difference between this embodiment and the previous embodiment is that not only tie rod 10 but also tie rod 9 is fastened to the connecting plate 11 via a fixing nut 14. In this embodiment, a washer 21 is arranged between each fixing nut 14 and the connecting plate 11. However, the washer 21 can also be omitted.

[0050] Figures 20 to 25 This shows different implementation variations for the element used to introduce pressure in the first building component 2. According to... Figure 20 and Figure 21 In this embodiment, pressure is introduced via a pressure bar. According to... Figure 22 and Figure 23In one embodiment, a pressure bearing 41 for pressure transmission is provided. The width m of the pressure bearing 41, measured along the longitudinal direction 28, is not constant along the transverse direction 29, but increases from the supporting angle steel 17 toward the first structural member 2. In this embodiment, the pressure bearing 41 extends beyond the insulator 5 into the first structural member 2. However, it can also be configured such that the pressure bearing 41 terminates at the first longitudinal side 6 of the insulator 5 and abuts against the concrete of the second structural member to facilitate the introduction of pressure into the second structural member. Figure 22 As shown, the pressure bearing 41 extends relative to the bottom side 8 of the insulator 5 by a distance p measured along the height direction 30. The pressure bearing 41 advantageously extends in the middle region of the height of the supporting angle steel 17. Figure 23 As shown, the pressure bearing 41 rests approximately against the middle of the back side 54 of the support angle steel 17 along the longitudinal direction 28. The pressure bearing 41 supports the support angle steel 17 in the intermediate region between the side walls 18 of the support angle steel. By increasing the width m of the pressure bearing 41 toward the first building member 2, a sufficiently large area of ​​the concrete of the first building member 2 can be activated to introduce force. Typically, the second building member is made of concrete with a strength higher than that of the concrete in the first building member. The first building member 2 can be manufactured, for example, by cast-in-place concrete, while the second building member 3 is manufactured in a prefabrication plant. Thus, for force transmission, a smaller surface area for the pressure bearing 41 can be provided in the second building member 3 compared to the first building member 2.

[0051] According to Figure 24 and Figure 25 In this embodiment, an anchor 42 is provided for pressure transmission, which correspondingly has a widened head 43. Two anchors 42 are provided in this embodiment. The anchors 42 are relatively short, thus making this arrangement suitable for installation at a relatively shallow depth in the first building member 2 in this area.

[0052] Figure 26 A variant embodiment is shown in which a second tie rod 10 extends through the insulator 5. In this embodiment, the insulator 5 is constructed separately. A first portion 52 of the insulator 5 is held at a first structural member 2, while a second portion 53 of the insulator is held at a second structural member 3. In this embodiment, a first compression rod 19 and a shear rod 16 extend through the first portion 52 of the insulator 5. The second tie rod 10 extends through the second portion 53 of the insulator 5. Similarly, a one-piece or multi-piece design of the insulator 5 and / or other arrangements of the portions of the insulator 5 may be advantageous. A supporting angle steel 17 is arranged on the outside of the insulator 5. In the case of viewing along the longitudinal direction 28, the supporting angle steel 17 and the insulator 5 are placed side by side without overlapping.

[0053] In this embodiment, the first pull rod 9 is welded to the connecting plate 11, but it can also be fastened to the connecting plate 11 with screws. The connecting plate 11 abuts against the first longitudinal side 6 of the insulator 5. Adjacent to the connecting plate 11, the first building member 2 has a recess 15. The connecting plate 11 has an opening for the second pull rod 10, through which the connecting plate can be inserted into the receiving portion and where it can be secured by a fixing nut 14. Figure 2 It was tightened.

[0054] According to Figure 27 In one embodiment, the supporting angle steel 17 is arranged in the insulator 5, preferably in a corresponding receiving portion of the insulator 5. The second building member 3 has an end side 49 facing the insulator 5. At the end side 49, the second building member 3 is positioned according to... Figure 27 In this embodiment, a support (or pad, or Auflager) 48 extending beyond end 49 into the insulator 5 is provided. This support may be made of, for example, concrete, particularly ultra-high strength concrete, or metal. The support 48 can be anchored in the second building member 3 in a suitable manner, for example, via a reinforcing element not shown. If the second building member 3 is assembled in the first building member 2, the support 48 is positioned in the supporting angle steel 17, and the second tie rod 10 is pushed into the recess 15 of the first building member 2 through a corresponding opening in the connecting plate 11 and tightened thereon.

[0055] according to Figure 26 and Figure 27 The embodiment shows a building member with increased thickness. Here, the shear bar 16 does not extend at the height of the first tie bar 9 in the first building member 2, but extends at intervals along the height direction 30 from the first tie bar.

[0056] Other advantageous implementations are obtained by any combination of the embodiments.
