Description

[0001] The present invention relates to a device for connecting a first load-bearing building part, in particular a wall, and a second supported building part, in particular a stair part or a landing slab, according to the preamble of claim 1, as well as to a building section comprising a first load-bearing building part and a second supported building part according to claim 13. Furthermore, the present invention relates to a method for connecting a first load-bearing building part to a second supported building part according to claim 14.

[0002] Installation elements, in particular for transmitting forces between a first load-bearing building part and a second supported building part, are known, for example, from DE 10 2013 100 356 A1 or DE 10 2021 100 348 A1. The installation elements are usually integrated into a prefabricated element, which is to be connected to the building parts surrounding the prefabricated element on a construction site. The forces acting on the second supported building part, in particular the weight of the building part, are to be transferred to and diverted from the first load-bearing building part via a support element arranged in the installation element. In addition to the weight, bending moments and shear forces acting on the support element can also be transferred and diverted accordingly.To align the building sections and the support element with each other, the installation elements are designed as hollow bodies and are fixed in place on site after the support element and the precast element have been aligned and positioned accordingly. For this purpose, the support element engages in a recess in the first building section. The support element is movable within the installation element only along its longitudinal axis and thus essentially perpendicular to the weight force and is otherwise fixed in position. To align the precast element and the building section with each other, the recess in the first building section must therefore be sufficiently large. The support element is aligned and positioned by placing panels in the recess.The recess is then closed with mortar so that after the mortar has hardened, the precast element is connected to the first part of the building and can absorb and transmit the corresponding forces.

[0003] The building components can, for example, be a building wall as the first load-bearing building component and a stair section or a landing slab as the second load-bearing building component, with both building components preferably being made of concrete. In particular, the building components can be designed as prefabricated elements.

[0004] When aligning the second supported building section relative to the first building section, with the sleeve and holder firmly fixed in the building sections, certain adjustment tolerances are required in order to align the building sections in the predetermined position relative to one another. To make this possible, at least one hollow body, either the sleeve or the holder, should be of appropriate size and designed with tolerance compensation so that when the support element is fixed in one building section, for example by means of a precisely fitting sleeve or holder, the second building section can be positioned accordingly by means of the tolerance compensation. However, to fix the support element, the recess or the hollow body must be filled in the building section in which the support element has corresponding play.However, since the backfill material has a certain fluidity, at least a certain sealing of the cavity is required as a clearance for the positioning of the building parts relative to each other in order to prevent the backfill material from running out of this clearance.

[0005] For this purpose, it is known in the prior art, for example, to insert a hose seal in the area between the two building sections. However, this is associated with a high level of effort directly on site at the construction site and at the same time is difficult to implement because the joint can only be very shallow and thus the distance between the first load-bearing building section and the second supported building section can be minimal. On the other hand, the joints can also be very wide, for example up to 100 mm, so that a sealing effect over such a width is difficult to achieve. Furthermore, it cannot always be guaranteed that such seals will seal sufficiently well. This means that leakage of the backfill material cannot be effectively prevented. This design can also create sound bridges between the building sections. A high level of effort and exact precision is required to effectively prevent sound bridges.

[0006] WO 2018 / 071987 A1 discloses a device for connecting two similar concrete elements that are movable relative to one another in a plane by means of a dowel rod. The concrete elements are, in particular, floor slabs. The dowel rod is movably arranged in a sleeve in one floor slab and sealed by a membrane at a sleeve opening through which the dowel rod is guided in a sealing manner. In the second floor slab, the dowel rod is fixed simply by encasing it in concrete.

[0007] From WO 2020 / 124165 A1, a further device for connecting two similar concrete elements that are movable relative to one another in a plane by means of a tendon is known, wherein the tendon is movably arranged in a sleeve and is guided by a seal at the open end of the sleeve, which seal is designed to be laterally movable together with the tendon.

[0008] The aforementioned devices are particularly used when the floor slabs are manufactured one after the other and the curing of the concrete takes place at different times, which creates stresses due to the different stages of curing of the concrete. This device then allows a certain flexibility for adjusting the joint between the two floor slabs. The disadvantage of these devices is that they only allow movement essentially along the direction of the dowel rod and, if necessary, in a lateral direction. However, adjusting the height of the two elements relative to each other is neither possible nor desirable, since this design principle is intended to prevent an offset in the height of the two adjacent floor slabs. The position of the opening remains essentially unchanged; only the orientation and position of the dowel rod changes within the sleeve.In addition, such devices are unsuitable for connecting a load-bearing and a supported part of a building, as they cannot permanently transfer a corresponding load.

[0009] It is therefore an object of the present invention to provide a device for connecting a load-bearing and a supported building part, a building section and a method for connecting a load-bearing and a supported building part, which enable a simple and rapid connection of two, in particular prefabricated, building parts on site with the required installation tolerance.

[0010] It is a further object of the present invention to provide a device for connecting a load-bearing and a supported building part, a building section and a method for connecting a load-bearing and a supported building part, which in a simple and safe manner prevent or at least largely prevent a simplified installation with standard construction tolerances and the associated leakage of a filling material from a hollow body for the support element.

[0011] These and other objects are achieved by a device for connecting a first load-bearing building part to a second supported building part according to claim 1, a building section comprising a first load-bearing building part and a second supported building part according to claim 13, and a method for connecting a first load-bearing building part to a second supported building part according to claim 14. Advantageous embodiments of the device for connecting are set out in claims 2 to 12. A further advantageous embodiment of the method for connecting is set out in claim 15.

[0012] The device for connecting a first and a second building part is particularly designed to carry out a method for connecting a first building part to a second building part. The method for connecting a first load-bearing building part to a second supported building part is particularly designed to be carried out with a device for connecting a first load-bearing building part to a second supported building part.

[0013] The device according to the invention for connecting a first load-bearing building part, in particular a wall, and a second supported building part, in particular a stair part or a landing plate, comprises a sleeve arranged in the second supported building part with a sleeve body which extends substantially longitudinally in an extension direction within the second supported building part and, in the installed state, has a sleeve opening towards the first load-bearing building part, wherein a joint is preferably formed between the first load-bearing building part and the second supported building part.Furthermore, the device according to the invention comprises a receptacle arranged in the first supporting building part, wherein a support element which is elongated in the direction of extension and movable in the direction of extension and has a support element cross-section is arranged within the sleeve body, which support element is additionally arranged in the sleeve body and / or in the receptacle so as to be movable in a plane perpendicular to the direction of extension in order to align the second supported building part with respect to the first supporting building part and can be brought into engagement with the receptacle through the sleeve opening.

[0014] The device according to the invention is characterized in that a diaphragm for sealing the sleeve and / or the receptacle is arranged along the direction of extension in an engagement region of the carrier element, wherein the diaphragm has an opening for receiving the carrier element, which opening is variable in its position according to the movement and arrangement of the carrier element in the lateral direction and in the vertical direction.

[0015] Due to the freedom of movement of the support element in the sleeve body and / or in the receptacle, the support element can be positioned accordingly in the building section, whereby the building section can thereby be brought into the desired position. The cover with a support element guided through the opening prevents the backfill material from flowing out of the hollow body in the sleeve and / or the receptacle when the hollow body in the sleeve and / or the receptacle is filled with backfill material. At the same time, the position-adjustable opening in the cover also allows it to move with the support element depending on the alignment of the building sections. The necessary freedom of movement of the support element during alignment is therefore not restricted, but at the same time a seal is achieved for the hollow body in the sleeve and / or the receptacle. The position of the opening orThe support element can be adjusted both vertically and laterally thanks to the mobility of the opening, thus enabling, in particular, height adjustment or height alignment of the two building sections to one another. The first load-bearing building section can thus be aligned on site with the second supported building section. Overall, this increases flexibility in the alignment of the two building sections to one another and, at the same time, ensures that the sleeve and / or the holder are sealed. In addition, changing the position of the opening allows the support element to remain essentially longitudinally aligned in the direction of extension, thus enabling optimal load transfer.

[0016] In a preferred embodiment, at least one building component is a prefabricated building component. Preferably, the first load-bearing building component and the second supported building component are prefabricated building components. Thus, the building components are prefabricated elements in which the sleeve or the receptacle are already embedded in the building component and firmly fixed there.

[0017] In an advantageous embodiment of the device, the aperture is arranged in an aperture plane which is formed substantially perpendicular to the direction of extension.

[0018] In particular, the extension direction forms the normal vector of the plane perpendicular to the extension direction, in particular the aperture plane.

[0019] In a preferred embodiment, the cover is arranged in the sleeve body and / or on the sleeve, in particular at the sleeve opening, and / or on the receptacle and / or in the joint between the first load-bearing building part and the second supported building part. Depending on the design of the sleeve body or the receptacle with regard to the corresponding component, which allows the corresponding clearance for aligning the support element or the building parts, there are various possibilities for arranging the cover so that the hollow body is sealed accordingly. Arranging the cover directly at the sleeve opening is particularly preferred, so that after aligning the building part and the support element, the entire sleeve can be filled with a filling material.

[0020] Preferably, the panel is variable, in particular inflatable and / or compressible. Thus, it can be flexibly adapted to the corresponding support element, in particular to different support element cross-sections.

[0021] Alternatively, or preferably additionally, the cover is constructed in several parts. A cover composed of several parts can also be adapted to the specific circumstances, which in particular enables a better seal of the hollow body in the sleeve and / or the receptacle.

[0022] Further alternatively or preferably additionally, the diaphragm is substantially rigid and / or at least parts of the diaphragm are substantially rigid. A substantially rigid diaphragm or an at least partially rigid diaphragm has the advantage of providing an improved limiting effect compared to the filler material.

[0023] An advantageous embodiment of the device is characterized in that the panel has a frame and at least one cover that is movable relative to the frame and in which the opening is formed. In particular, the frame has a U-shaped profile in its cross-section, in which the at least one cover is movably arranged. The construction of the panel from frame and cover enables movement of the cover within the frame without negatively affecting the sealing effect of the panel. This allows a certain degree of flexibility on the one hand, and achieves the desired sealing effect on the other.

[0024] Preferably, the frame and / or the at least one cover is substantially rigid.

[0025] Alternatively, or preferably additionally, the at least one cover is at least partially formed from a flexible material or comprises a flexible material. Using a flexible material as the cover, the cover can conform even better to the carrier element with its carrier element cross-section, thus achieving an improved sealing effect of the cover against the hollow body in the sleeve and / or receptacle.

[0026] In an advantageous embodiment of the device, two covers are arranged one behind the other, with one cover being designed to be movable essentially only in the lateral direction and the other essentially only in the vertical direction. This configuration can be easily implemented due to the cover's mobility in only one direction.

[0027] Particularly preferably, the covers each have an elongated hole extending substantially in the fixed direction of the cover, with the opening for the support element being formed by an open area of ​​overlap between the elongated holes of the two covers. Thus, a cover can be easily realized via two covers and the frame, which is easy to manufacture and provides the desired sealing.

[0028] In a further preferred embodiment, an opening area of ​​the opening substantially corresponds to the carrier element cross-section. Thus, the opening area of ​​the opening is substantially adapted to the carrier element to achieve a corresponding seal. Preferably, a gap between the carrier element cross-section and the opening is less than or equal to 1 mm. In particular, the gap is in the range of 0.1 mm to 0.5 mm.

[0029] Alternatively or preferably additionally, a seal is arranged at the opening, in particular a seal running around the opening. Further alternatively or preferably additionally, a seal is arranged on the support element in the region of the cover, in particular a seal enclosing the support element. The seal provides additional sealing around the support element when the support element is passed through the opening, so that material inserted into the hollow body cannot escape through the essentially closed hollow body. In particular, the seal can be used to specifically seal the gap between the support element cross-section and the opening.

[0030] A preferred embodiment is characterized in that the support element is secured within the receptacle or sleeve in all directions except the direction of extension. This ensures that the support element is secured and fixed in the receptacle or sleeve except for the direction of extension, whereby alignment and positioning of the support element is only possible in the other, corresponding element, i.e., the sleeve or receptacle.

[0031] In a further preferred embodiment, the support element can be fixed within the sleeve body and / or the receptacle after its alignment. This fixation secures the support element in its position, so that it remains appropriately aligned and allows force transmission from the second supported building part to the first supporting building part.

[0032] Alternatively, or preferably additionally, the sleeve body and / or the receptacle can be filled with a filling material for fixing the support element and / or after fixing the support element. By filling the sleeve body and / or the receptacle with a filling material, the support element is finally fixed in its alignment and this creates a connection between the support element and the first load-bearing building part or the second supported building part, depending on which hollow body is filled in which building part. The filling material can preferably be a pourable, flowable and / or hardenable material. In particular, the filling material is a mortar or cast concrete.

[0033] In a preferred embodiment, the receptacle and / or the sleeve has a filling opening on the sleeve body, wherein the sleeve can be filled via the filling opening through a building section opening in the second supported building part and / or the receptacle can be filled via the filling opening through a building section opening in the first supporting building part. The hollow body in the sleeve and / or the receptacle can be easily filled with the filling material via the corresponding building section opening. In particular, the filling material can be fed into the corresponding hollow body via the building section opening without the need for special precautions or systems. Filling can take place either directly via the building section openings or via hoses and pump systems which feed the filling material into the hollow body via the corresponding building section opening.Preferably, the building section opening is located in a surface of the building section. Filling preferably occurs via the filling opening from above, allowing the filling material to flow into the hollow body by gravity.

[0034] Preferably, the support element is movable in the plane perpendicular to the direction of extension in the vertical direction by a total of at least 10 mm, preferably at least 20 mm, particularly preferably at least 30 mm. Preferably, the support element is movable in the vertical direction by a total of a maximum of 80 mm, preferably a maximum of 50 mm. Due to the mobility in the vertical direction, the support element can be moved into the appropriate position for the vertical alignment of the building part.

[0035] Alternatively, or preferably additionally, the support element is movable in the plane perpendicular to the direction of extension in the lateral direction by a total of at least 10 mm, preferably at least 20 mm, particularly preferably at least 30 mm. Preferably, the support element is movable in the lateral direction by a total of a maximum of 80 mm, preferably a maximum of 50 mm. Thus, the support element can be moved and aligned accordingly both in the vertical and lateral directions.

[0036] A preferred embodiment is characterized in that the joint between the first load-bearing building part and the second supported building part is free of intermediate elements. In particular, the joint is free of filling material. Thus, the joint initially only provides a connection between the building parts via the support element, but no additional elements are arranged that could, for example, cause sound transmission or the like.

[0037] Alternatively, or preferably additionally, an at least partially flexible sleeve is formed on the support element, which can be arranged in the joint between the receptacle and the sleeve. By inserting a sleeve into the joint, the joint area is insulated, for example, and the transmission of sound or vibrations between the building components can be better decoupled. In particular, the sleeve can be a fire protection sleeve or a joint sleeve or joint plate.

[0038] In a preferred embodiment, insulating elements are arranged in and / or around the sleeve and / or in and / or around the receptacle. The insulating elements are designed, in particular, for sound insulation. Appropriate insulation of the sleeve and / or the receptacle with insulating elements dampens vibrations, thereby dampening sound transmission. The insulating elements can also serve for thermal insulation, which also minimizes heat transfer between the individual building components.

[0039] In a further preferred embodiment, the sleeve body has ribs for anchoring in the second supported building part. The ribs secure the anchoring of the sleeve body in the second supported building part, which is made of concrete and is in particular a precast concrete component.

[0040] Alternatively, or preferably additionally, the cover protrudes from the sleeve body or the receptacle. In particular, the cover is flush with an edge of the second supported building part or the first load-bearing building part. The cover thus has a larger cross-section in a plane perpendicular to the direction of extension than the sleeve body or the receptacle, which can additionally anchor it in the building part. The flush fit with an edge of the building part simplifies the positioning and alignment of the support element, since the cover is more clearly visible due to its arrangement on an outer edge of the building part.

[0041] Preferably, the support element and / or the panel and / or the frame and / or the cover are made of a metallic material, in particular a metal or an alloy. In particular, this is steel. This enables good force transmission, whereby even large forces can be transmitted without difficulty. The steel can preferably be a stainless steel, in particular a stainless steel, or a post-processed and / or coated steel, for example, by hot-dip galvanizing.

[0042] Alternatively, or preferably additionally, the panel and / or the frame and / or the cover are made of a plastic. In particular, the plastic can be a thermoplastic and / or injection-moldable plastic. The panel, frame, and / or cover can be manufactured cost-effectively in large quantities from plastic. Adapting the elements to the respective conditions, in particular to the support element with its support element cross-section and the sleeve body, is also possible with a plastic element.

[0043] In a further preferred embodiment, the cover is formed integrally with the sleeve and / or the receptacle. The integral design of the cover and sleeve and / or receptacle further simplifies their manufacture. In particular, the frame of the cover can be formed integrally and thus materially bonded to the sleeve and / or the receptacle. The corresponding element is thus formed in one piece.

[0044] Alternatively, or preferably additionally, the cover is connected to the sleeve and / or the holder in a force-fitting, friction-fitting and / or positive-locking manner. The cover or the individual elements of the cover, in particular the frame, can be plugged onto the sleeve and / or the holder or can be plugged onto the sleeve and / or the holder. In particular, the modular design makes it possible to adapt the cover or the individual elements of the cover to the conditions on site. This achieves greater flexibility, in particular with regard to the design, size of the cover and the opening. The connection between the cover and the sleeve and / or the holder is made in particular by a snap-in, clip-in and / or adhesive connection.

[0045] In a further preferred embodiment, the first load-bearing building part and / or the second supported building part is a cast component, in particular a component cast from concrete. In particular, the second supported building part can be a precast concrete element manufactured in a precast concrete plant. The precast element is then aligned and positioned accordingly with respect to a first load-bearing building part on site at the construction site.

[0046] As a further solution, a building section is specified, comprising a first load-bearing building part, in particular a wall, and a second supported building part, in particular a stair part or a platform plate, as well as a device for connecting a first load-bearing building part and a second supported building part as set out above, wherein a sleeve is formed in the second supported building part and a receptacle is formed in the first load-bearing building part.

[0047] The corresponding building section thus comprises, on the one hand, the first supporting building part and the second supported building part as well as the aforementioned device for connecting the two building parts.

[0048] As yet another solution, a method is provided for connecting a first load-bearing building part, in particular a wall, to a second supported building part, in particular a stair part or a landing slab, wherein a sleeve with a sleeve body and a support element movable in its direction of extension are arranged in the second supported building part, wherein a receptacle for the support element is formed in the first load-bearing building part, and wherein the support element is additionally movable in the receptacle and / or in the sleeve body in a plane perpendicular to the direction of extension. The method for connecting the two building parts comprises the steps: A) Arranging and aligning the second supported building part relative to the first supported building part; B) Positioning the support element such that it engages in the receptacle, wherein the support element is guided through an opening of a cover on the sleeve and / or the receptacle, wherein a position of the opening can be changed in accordance with the movements and arrangement of the support element in the lateral and vertical directions; C) Casting the sleeve and / or the receptacle with a hardenable filling material for fixing the support element and thus the first supportive building part to the second supported building part, wherein the spreading of the filling material is limited by the cover and the cover; and D) Hardening the filling material.

[0049] The aforementioned method connects the two building sections to each other, with the movement of the pourable and / or flowable backfill material being limited precisely by the use of a diaphragm with a corresponding opening. The support element is operatively connected to both the receptacle in the first supporting building section and the sleeve in the second supported building section, thus ensuring appropriate force transmission after the backfill material has hardened.

[0050] In a preferred embodiment of the method, after method step A), the second supported building part is temporarily fixed and / or supported, and after method step D), the temporary fixation and / or support is removed again. Thus, only a brief support of the corresponding second supported building part is required until the filling material has hardened, so that a corresponding force transmission and force dissipation from the second supported building part to the first supporting building part takes place via the device for connecting the building parts.

[0051] Preferably, the first load-bearing building part and / or the second supported building part can be a component that was manufactured using 3D printing. Concrete or other hardenable materials can be used to produce the corresponding building parts within the scope of 3D printing. The 3D printing of building parts is essentially based on the use of extrusion and / or injection molding techniques.

[0052] To manufacture cast building components, formwork is used that is designed to fit the size of the desired building component, and into which the sleeve bodies and / or the receptacles are inserted and secured. Formwork is particularly used for this purpose, allowing for easy fixation of the built-in elements in the form of sleeves and / or receptacles. Part of this formwork can, for example, include a formwork table.

[0053] Preferably, the frame is designed to be completely closed. Preferably, the cover is inserted into the frame before assembly. Alternatively, or preferably additionally, the cover is made of a flexible material and can be inserted into the completely closed frame.

[0054] Further preferably, the height and configuration of the cover are designed such that the cover is always guided within the frame and has no direct openings other than the opening for the support element in any position of the cover within the frame. This prevents the filling material from escaping from the area of ​​the sleeve and / or the receptacle separated by the cover.

[0055] The invention is explained and described in more detail with reference to the following figures. Figures 1a and 1b each show a building section with different embodiments of a device for connecting building parts; Figure 2 shows a perspective view of a sleeve; Figure 3 shows a sectional view of a sleeve with a cover; Figure 4 shows a cover according to one embodiment; Figure 5 shows an embodiment of a receptacle with a cover; Figure 6 shows a further embodiment of a cover; and Figures 7a), 7b), 7c) show individual views of the components of the cover from Figure 6 .

[0056] In Figures 1a and 1bEach of the drawings shows a building section 1 according to the invention in different embodiments. The building section 1 comprises a first load-bearing building part 2. In the first building part 2, a receptacle 9 is arranged, into which a support element 10 can be inserted. The building section 1 further comprises a second supported building part 3, which is spaced from the first load-bearing building part 2 by a joint 4. The second supported building part 3 comprises a sleeve 5 with a sleeve body 6, which has a sleeve opening 7 on the side facing the first building part 2. In the building section 1, the support element 10 is not only operatively connected to the receptacle 9, but also extends via the joint 4 into the sleeve body 6 of the sleeve 5 in the second supported building part 3. The support element 10 extends in an extension direction 19.

[0057] The first load-bearing building part 2 is a wall, whereas the second supported building part 3 in this case is a stair part, in particular a landing slab of a staircase. The second supported building part 3 is made of concrete, being a precast concrete element. In the precast concrete element as the second supported building part 3, the corresponding elements, in particular one or more sleeves 5, have already been inserted in the precast concrete plant and anchored in the concrete of the precast element.

[0058] In Figure 1a), the receptacle 9 is designed such that it is essentially a precise fit to the support element 10 and can accommodate the latter with its support element cross-section. The sleeve 5 in the second supported building part 3 has a greater extent or dimension than the support element 10 in the plane perpendicular to the direction of extension 19, whereby the second supported building part 3 can be aligned and positioned relative to the first supporting building part 2 despite the support element 10. The support element 10 is also movable in the direction of extension 19 within the sleeve body 6.After alignment of the second supported building part 3 to the first supporting building part 2, the sleeve body 6, in the outer surface of which a filling opening 16 is formed, is filled with a flowable and pourable filling material 15, in this case mortar, via a building section opening 17 and a filling module 22, so that after hardening of the filling material 15, a firm connection suitable for transmitting forces in the second supported building part 3 to the first supporting building part 2 is formed.

[0059] To prevent the filling material 15 from escaping from the sleeve body 6 when filling the sleeve body 6, as shown in Figure 2As shown, a cover 11 with an opening 12 for the support element 10 is arranged at the sleeve opening 7, whereby the sleeve body 6 is essentially closed when the support element 10 is passed through the opening 12 of the cover 11 and thus forms a boundary for the filling material 15. This prevents the filling material 15 from escaping from the sleeve body 6 into the joint 4. The joint 4 thus remains freely accessible.

[0060] Figure 1b) shows a further embodiment of a building section 1, in which the sleeve 5 is designed substantially according to the dimensions of the support element 10, in particular the support element cross-section in the plane perpendicular to the extension direction 19. The support element 10 is fixed in the sleeve body 6 substantially in all directions except for the extension direction 19. The support element 10 can only be moved in the extension direction 19, so that it can be brought into engagement with the receptacle 9 in the first load-bearing building part 2. Compared to the embodiment in Figure 1a ) is in the embodiment in Figure 1b) the receptacle 9 is designed in such a way that it allows a movement of the support element 10 for aligning the second supported building part 3 with the first supporting building part 2. In this case, the receptacle 9, which is larger than the support element cross-section, also allows a movement in the vertical direction 21, which extends essentially perpendicular to the extension direction 19, as well as in the lateral direction 20, which in the present case Figure 1b ) extends essentially into the plane of the sheet. The receptacle 9 is surrounded by insulating elements 18 for sound insulation.

[0061] In Figure 1b) On the side of the receptacle 9 facing the joint 4, a cover 11 is arranged, in which an opening 12 is formed for receiving the support element 10. To fix the support element 10, after the building parts 2, 3 have been aligned with one another, a filling material 15 is also introduced, but now into the receptacle 9, whereby the cover 11 limits and, in particular, prevents the filling material 15 from escaping into the joint 4.

[0062] In addition to the two embodiments shown, it is also possible for both the sleeve 5 in the second supported building part 3 and the receptacle 9 in the first supporting building part 2 to have a cross-section larger than the support element cross-section, thus enabling a corresponding alignment of the building parts 2, 3 to one another both on the side of the first supporting building part 2 and on the side of the second supported building part 3. Accordingly, in this case, both the receptacle 9 and the sleeve 5 have a cover 11 to prevent the escape of the filling material 15 for fixing the support element 10 in its position.

[0063] In Figure 2The sleeve 5 is shown in more detail in a perspective view. The sleeve 5 comprises the sleeve body 6, on which ribs 8 are formed, thereby achieving improved anchoring of the sleeve 5 in the second supported building part 3, in particular in a concrete of the building part 3.

[0064] The sleeve 5 further has a filling opening 16 formed in the outer surface of the sleeve body 6. In the present case, a filling module 22 is arranged at the filling opening 16, bridging a distance to the (not shown) building section opening 17, thus enabling filling of the sleeve body 6 via the building section opening 17 after aligning the building parts 2, 3 with one another. The height of the filling module 22 is configured perpendicular to the direction of extension 19 such that it is substantially flush with the surface of the building part.

[0065] The aperture 11 is arranged at the sleeve opening 7 and has an opening 12 for the passage of the support element 10 (not shown). The aperture 11 protrudes beyond the sleeve body 6 and thus has a larger aperture cross-section than the sleeve cross-section.

[0066] In the present case, the cover 11 is formed from a frame 13 and a cover 14 which is movable within the frame 13 and in which the opening 12 for the support element 10 is located. The sleeve 5 is arranged in the building part 3 surrounding the sleeve 5 such that the cover 11 is essentially flush with a side surface of the building part 3. Furthermore, the cover 11 is formed integrally with the sleeve 5 and is thus materially connected to it. Alternatively, the cover 11 can also represent a separate element which is connected to the sleeve 5 in a force-fitting and / or form-fitting manner, for example via locking elements. Further alternatively, the cover 11 can also be arranged within the sleeve 5 or within the sleeve body 6.

[0067] A sectional view of the Figure 2 The sleeve 5 shown is partially shown in Figure 3shown. Here, the ribs 8 on the sleeve body 6 of the sleeve 5 are again shown, which protrude over the sleeve body 6 into the building part 3 (not shown) for anchoring. The illustration also shows that the frame 13 of the panel 11 has a substantially U-shaped profile in its cross-section, in which the cover 14 is freely movable. The cover 14 protrudes to a certain extent into the frame 13 of the panel 11, so that depending on the position of the cover 14 in the frame 13, the cover 14 is always guided in the frame 13 and there is no further opening to the environment other than the opening 12. The frame 13 and the cover 14 are designed such that the cover 14 is freely movable in the frame 13. The size of the cover 14 is such that the sleeve body 6 is essentially sealed off from the environment by the panel 11, with the exception of the opening 12.The cover 14 is thus guided in the frame in every position of the opening 12. In particular, when filling the sleeve body 6 with a filling material 15, the design of the cover 11 consisting of the frame 13 and the cover 14 prevents any filling material 15 from escaping to the outside via the frame 13, since the opening 12 is additionally covered by the support element 10 (in . Fig. 3 not shown) is completely closed.

[0068] Both the frame 13 and the cover 14, in particular the panel 11 as a whole, are made of a substantially rigid material, in this case plastic. Alternatively, the frame 13 and the cover 14 can also be made of steel. The cover 14 can further have a seal in the region of the opening 12, which seal is preferably made of a flexible material, whereby when the carrier element 10 is passed through the opening 12, a further sealing effect is achieved around the carrier element 10 and the sleeve body 6 is thus essentially completely sealed off from the environment in the region of the panel 11. Furthermore, the frame 13 can be made of two or more parts, whereby it can be easily assembled and the cover 14 can be inserted into the frame 13. Alternatively, the cover 14 as well as the entire panel 11 can be made of several parts.

[0069] In Figure 4the panel 11 is shown in a perspective view. In the present case, the panel 11 is also constructed from a frame 13 and a cover 14, in which the opening 12 for the passage of a support element 10 (not shown) is located. The opening 12 is designed such that the opening area essentially corresponds to the cross-section of the support element. Alignment of the position of the support element 10 relative to the frame 13 is made possible after the support element 10 has been passed through the opening 12 by the cover 14, which is movable in the frame 13. In addition, a seal can be arranged on the cover 14 in the region of the opening 12, which seal conforms to the support element 10 as it is passed through. Alternatively, a seal or sleeve can also be arranged on the support element 10 itself, which enables further sealing of the opening 12.

[0070] As shown, the cover 11 forms an independent structural element that can be connected to the sleeve body 6 in the second supported building part 3 and / or the receptacle 9 in the first supporting building part 2. The use of the cover 11 shown here is therefore not limited to use with the sleeve 5. Rather, this cover 11 can also be used on an open side of the receptacle 9 facing the joint 4, wherein the cover 11 is to be connected as a single element to the receptacle 9 in a force-fitting and / or material-fitting and / or form-fitting manner for a corresponding sealing effect.

[0071] Figure 5 shows an embodiment of a receptacle 9 with a diaphragm 11' integrally formed on the receptacle 9, in which an opening 12 is formed. In contrast to the diaphragm 11 in the Figures 2 to 4 The aperture 11' has Figure 5via a cover 14' made of a compressible material, which can adapt to the support element cross-section of the (not shown) support element 10 as it is passed through. This shape of the cover 11' also enables sealing against the hollow body inside the receptacle 9, so that when the receptacle 9 is filled, the filling material 15 cannot escape from the receptacle 9 via the opening 12. Alternatively, in this embodiment, the cover 14' can also consist of an expandable material, which expands under certain conditions after the support element 10 has been passed through and conforms to the support element cross-section of the support element 10 to achieve a sealing effect.

[0072] In Figure 6A further embodiment of the panel 11' is shown, which is constructed in several parts. The panel 11' consists of a frame 13 and two covers 14, 14', each arranged one behind the other in front of the frame 13. The distance between the covers 14, 14' and between the frame 13 and the cover 14 is approximately 0.5 mm.

[0073] The individual components of the aperture 11' according to Figure 6 are in the Figures 7a), 7b) and 7c ) are presented in detail. Figure 7a ) shows the frame 13, which has a substantially rectangular opening. In Figure 7b ) the cover 14 is shown, in the center of which a slot 12a is formed, which extends essentially in the vertical direction 21. The cover 14 is narrower in the lateral direction 20 compared to the frame 13. In Figure 7c) the second cover 14' is shown, which is rotated by 90° relative to the cover 14 and thus has an elongated hole 12b which extends substantially in the lateral direction 20.

[0074] The cover 14 is arranged in the frame 13 so as to be movable in the lateral direction 20, whereas the second cover 14' can move essentially in the vertical direction 21. The overlap of the two elongated holes 12a, 12b forms the opening 12 within the panel 11', through which the support element 10 (not shown) is passed. The width of the elongated hole 12a in the lateral direction 20 essentially corresponds to the width of the support element 10 in the lateral direction 20, whereas the height of the elongated hole 12b in the vertical direction 21 essentially corresponds to the height of the support element 10 in the vertical direction 21. This ensures that the opening 12 formed by the overlap of the two elongated holes essentially corresponds to the cross-section of the support element.The two covers 14, 14' also allow the position of the opening 12 to be adjusted in the vertical direction 21 and lateral direction 20, so that the support element 10 (not shown) can be arranged accordingly with respect to the first supporting building part 2 and the second supported building part 3.
