Description

[0001] The present invention relates to a module for filling an installation element according to claim 1, an installation element for a precast element according to claim 11, a precast element made of concrete according to claim 14, and a method for producing a precast element made of concrete according to claim 15.

[0002] Installation elements, particularly for force transmission between a first load-bearing building component and a second load-bearing building component, are known, for example, from DE 10 2013 100 356 A1 or DE 10 2021 100 348 A1. These installation elements are usually integrated into a prefabricated element, which is to be connected to the surrounding building components on a construction site. A support element arranged within the installation element is intended to transmit and dissipate the forces acting on the second load-bearing building component, in particular the weight of the building component, to the first load-bearing building component. In addition to weight, bending moments and shear forces acting on the support element can also be transmitted and dissipated accordingly.To align the building components with each other and with the support element, the installation elements are designed as hollow bodies and are fixed on-site after the support element and the precast element have been aligned and positioned accordingly. The support element engages in a recess in the first building component, whereby the support element is only movable along its longitudinal axis within the installation element, and thus essentially perpendicular to the force of gravity, and is otherwise fixed in its position. Therefore, the recess in the first building component must be sufficiently large to align the precast element and the building component. The support element is aligned and positioned by placing plates within the recess.The recess is then sealed with mortar, so that after the mortar has hardened, the prefabricated element is connected to the first part of the building and can absorb and transmit corresponding forces.

[0003] KR 101 465 514 B1 discloses a module for filling an installation element according to the preamble of claim 1, more specifically it discloses a connecting element for reinforcing steel in a building element, wherein the connecting element has a feed opening for introducing mortar after connecting with the reinforcing steel, wherein a cover material for sealing is arranged on the feed opening, which is removed for filling the connecting element with mortar.

[0004] CN 108 908 691 A discloses a grouting sleeve for joining precast concrete slabs, comprising a main body and a support body, wherein the support body is designed to be screwed onto a reinforcing steel, and the main body and the support body are firmly connected to each other.

[0005] Furthermore, installation elements are also known which have a correspondingly large sleeve, whereby the support element is also movable in the direction of the weight force, and have a channel for filling the sleeve with mortar after alignment, wherein the recess in the first building part itself essentially corresponds to the cross-section of the support element and has no compensation possibility.

[0006] The building components can, for example, consist of a building wall as the first load-bearing component and a stair component, in particular a landing, as the second load-bearing component, with both components preferably being made of concrete. The second load-bearing component is usually in the form of a prefabricated element into which one or more built-in components are already integrated.

[0007] The production of precast concrete elements in a precast concrete plant is carried out using formwork. The formwork typically comprises a flat formwork table onto which further formwork elements are attached, corresponding to the shape of the precast element. Before the formwork is filled with concrete, the reinforcement and one or more embedded elements are positioned according to specifications and requirements. It is essential that the embedded elements are placed precisely on the formwork. This can be achieved, for example, by having a channel on the embedded element for later filling with mortar, with the channel being placed directly on the formwork table. The channel, which is usually made of plastic or metal, can be adjusted to the desired height by sawing and / or cutting.Alternatively, the channel can be positioned with its opening facing away from the formwork table, with the channel also being adjusted to the desired height.

[0008] The use of precast concrete elements with channels has generally proven effective, although these channels must be individually adapted for each element depending on the specific element, its position on the formwork, and the reinforcement. This is not always straightforward, however, as the installation space is usually very limited by the reinforcement. Furthermore, aligning the precast element on and relative to the formwork, especially vertical alignment, is only possible after considerable time and effort, as it typically requires precise adjustment of the channel height and compensation for any tilt.

[0009] Therefore, the object of the present invention is to provide a module for filling an installation element, an installation element, a precast concrete component, and a method for manufacturing a precast concrete component, all of which enable simple, safe, and quick alignment of the installation element. In particular, flexibility in handling the installation element is to be achieved.

[0010] A further object of the present invention is to provide a module for filling a built-in element, a built-in element, a prefabricated element and a method for manufacturing a prefabricated element, which enable flexible use with high tolerances.

[0011] These and other tasks are solved by a module for filling an installation element according to claim 1, by an installation element according to claim 11, and by a precast concrete element according to claim 14, as well as by a method for producing a precast concrete element according to claim 15.

[0012] Advantageous embodiments of the module for filling an installation element are set out in claims 2 to 10. Further advantageous embodiments of the installation element for a precast element are set out in claims 12 and 13. Still further advantageous embodiments of the method for manufacturing a precast element from concrete are set out in claims 16 and 17.

[0013] The module for filling an installation element is specifically designed for use with an installation element in a precast concrete element and comprises a frame for arranging the module at an opening of the installation element, with at least one side surface extending along a vertical axis of the frame. Furthermore, the module according to the invention for filling the installation element comprises a compensating element, which is arranged offset from the frame along the vertical axis, wherein the compensating element is guided in or on the frame and is movable relative to the frame, and wherein the compensating element is adjustable in its position relative to the frame.

[0014] The module according to the invention now allows it to be precisely adjusted and aligned with a reference mark of the formwork or reinforcement in the precast element, by making the compensating element movable relative to the frame and thus also adjustable. The compensating element and frame overlap in a region of the module, the degree of overlap being adjustable and changeable by the movable arrangement of the compensating element and frame of the module.

[0015] Preferably, the frame is attached to an opening of the installation element by placing it on top, snapping it into place, and / or connecting it. Alternatively, or preferably additionally, the frame can also be an integral part of the installation element.

[0016] The module according to the invention allows for flexible adjustment of the overall height, thereby compensating for unevenness or misalignment. For example, the module also enables the installation element to be tilted relative to a formwork, since the frame and the compensating element provide a certain degree of flexibility and corresponding alignment options. Thus, the module according to the invention increases and improves both flexibility and alignment options.

[0017] A preferred embodiment is characterized in that the frame and the compensating element form a channel extending along the vertical axis, the channel having a module opening for filling the installation element and an opening surface opposite the module opening, which is operatively connected to the opening of the installation element. The installation element is filled with a curable material, in particular a filler material, via the channel, whereby the channel itself can also be completely filled with the corresponding curable filler material during filling. In particular, the filler material can be a mineral material, for example, a mortar or grout.The hardenable filler material is characterized by the fact that it transitions from a viscous state during processing to a hardened state, in which the hardenable filler material exhibits a similar strength and stiffness to the surrounding material, in particular concrete.

[0018] In an advantageous embodiment, the module includes means for fixing the compensating element relative to the frame. In particular, these means are designed for reversible fixing of the compensating element relative to the frame. The compensating element can thus be fixed and secured in a desired position relative to the frame, so that a previously set position is retained. Because the compensating element can be fixed reversibly relative to the frame, it can also be readjusted at a later time.

[0019] Preferably, the means for securing are formed by locking elements and / or fixing elements which are arranged on the frame and / or the compensating element.

[0020] A preferred embodiment is characterized by the fact that at least one deformation element is arranged in and / or on the frame and / or on the compensating element, against which the compensating element is supported relative to the frame. The deformation element thus exerts a certain counterforce from the frame onto the compensating element, thereby improving alignment and positioning and achieving easier and simpler positioning. The deformation element can simultaneously also serve as a means for fixing the compensating element relative to the frame and thus contribute to positioning and fixing the relative positions of the compensating element and the frame.

[0021] Preferably, the at least one deformation element is elastic, in particular reversibly elastic. The elasticity of the deformation element allows for flexible and precise alignment of the compensating element relative to the frame, whereby the elasticity exerts a certain counter-pressure on the compensating element during positioning.

[0022] Preferably, the module forms part of a lost form, for example, a lost formwork.

[0023] Preferably, the deformation element is a body with a restoring force. In particular, this can be a spring or an expanding and / or pre-compressed material, such as a foam. The restoring force of the deformation element exerts a corresponding force on the compensating element relative to the frame, enabling precise and secure positioning of the compensating element relative to the frame. Furthermore, it is easier to align the module accordingly when a certain force is exerted on the compensating element by means of corresponding restoring forces. This ensures, in particular, that the module remains in the correct position after being fixed.

[0024] In a preferred embodiment, the deformation element is arranged section by section within the frame and / or on the compensating element. In particular, several deformation elements are distributed throughout the frame and / or on the compensating element. By arranging the deformation element or multiple deformation elements in sections within and / or on the frame and / or the compensating element, the amount of material required for the deformation element can be reduced, and the manufacturing of the module simplified. Furthermore, multiple deformation elements facilitate easier alignment of the compensating element relative to the frame, as each can be individually subjected to force without affecting the other deformation elements, for example, by displacing material from the deformation element. This further increases positioning accuracy.

[0025] Preferably, the frame and, in particular, the compensating element are essentially angular, preferably polygonal, and especially rectangular, with a deformation element preferably being arranged in each corner of the frame. A rectangular shape results in both the frame and the compensating element having a simple form that is also inexpensive and easy to manufacture. If the frame and / or the compensating element are polygonal, they can be regular or irregular.

[0026] Alternatively, or preferably additionally, the frame and, in particular, the compensating element are essentially round or oval. The shape of the frame and, in particular, the compensating element is essentially determined by the opening in the installation element.

[0027] In a further preferred embodiment, at least one recess for the at least one deformation element is formed in and / or on the frame. The recess creates a suitable space for the deformation element. The deformation element can thus be designed more flexibly. Furthermore, recesses can create areas in and / or on the frame into which the deformation element can deflect or be displaced when subjected to force. The recesses can be specifically adapted to the deformation element, in particular substantially corresponding to it.

[0028] Alternatively, or preferably additionally, the deformation element is arranged circumferentially on the compensating element and / or the frame. The deformation element can therefore be, in particular, a single object arranged circumferentially on or within the compensating element.

[0029] Alternatively, or preferably additionally, the compensating element comprises at least one pressure element which is operatively connected to the at least one deformation body. The pressure element transmits a corresponding force to the compensating element and onto the deformation body, distributing this force uniformly across the deformation body. The pressure element can be, in particular, a planar element, such as a plate or similar, thereby distributing the pressure uniformly over a larger area. The pressure element is preferably integrally formed with the compensating element.

[0030] A preferred embodiment is characterized by the fact that the deformation body has a compression path along its extension direction, which runs essentially parallel to the vertical axis, of up to 2 cm, preferably up to 3 cm, and particularly preferably up to 5 cm. Thus, the deformation body can be compressed or compressed along the vertical axis by a corresponding compression path, thereby enabling the compensating element to be positioned accordingly relative to the frame. The compression path thus provides a means of adjustment to set the overall height of the module.

[0031] In an advantageous embodiment of the module, the deformation element in the module, when installed, exhibits a minimum compression with a compression stroke of at least 0.1 cm, preferably at least 0.3 cm, and particularly preferably at least 0.5 cm. In the installed state, the minimum compression exerts a force on the deformation element, resulting in minimal compression of the element. This ensures that a certain counterforce is exerted on the compensating element by the deformation element, so that it can be held and fixed in its corresponding position. In particular, the minimum compression achieves a pre-compression or pre-stress.Furthermore, the minimum compression ensures that, due to the counterforce provided by the minimum compression, a seal can be achieved between the module opening and a surface covering this module opening and lying flush against the frame of the module.

[0032] Advantageously, the frame has a substantially U-shaped profile. This U-shaped profile allows the leveling element to be guided and at least partially supported within the frame. This prevents, for example, the leveling element from tilting relative to the frame.

[0033] Alternatively, or preferably additionally, the frame and / or the compensating element has at least one anchoring element for securing the compensating element to the frame. The anchoring element ensures that the compensating element and the frame are anchored to each other, preventing the two elements from being separated. It also ensures that the compensating element is always guided within and / or on the frame. Furthermore, the anchoring element ensures a maximum position of the compensating element relative to the frame, beyond which the compensating element cannot be moved without destroying the module.

[0034] An advantageous embodiment is characterized by the fact that the compensating element has a closing element on its side facing away from the frame. In particular, the closing element can be a plate, preferably a wooden plate, or an optical aperture. Preferably, the closing element closes the module opening substantially completely and / or seals the module opening against the environment. This prevents, for example, foreign substances from entering the module or the installation element. An optical aperture ensures that the module is flush with its surroundings or, when used in the visible area, presents a corresponding optical viewing surface. For example, the aperture can be made of stainless steel.

[0035] In a preferred embodiment, the end element is integrally formed with the compensating element; in particular, the compensating element and the end element form a body open only on one side, which is preferably substantially cuboid in shape, with an opening on the side facing the frame. To fill the installation element or module, the body is opened on its side away from the frame, preferably on-site, for example by sawing, drilling, milling, and / or cutting.

[0036] Advantageously, the leveling element and / or the frame are made of plastic. Plastic leveling elements and / or frames can be manufactured easily and cost-effectively in large quantities. It is preferred if the leveling element and frame are made of the same plastic. In particular, the leveling element and / or the frame can be manufactured by injection molding, which makes the large-scale production of the corresponding elements cost-effective.

[0037] Alternatively or preferably additionally, the leveling element and / or the frame is formed from a sheet metal panel, wherein the sheet metal panel preferably has a thickness of no more than 2 mm, particularly preferably no more than 1.5 mm, and most preferably no more than 1 mm. Leveling elements and frames made of sheet metal can, on the one hand, bear large loads and can be used in a wide variety of applications.

[0038] In a preferred embodiment, the leveling element has a height of 20 mm to 150 mm, preferably 40 mm to 100 mm. The leveling element can be designed and have a corresponding height depending on the application. The height of the leveling element does not correspond to the overall height of the module, which also includes the height of the frame. The overall height is to be understood as the vertical extent of both the leveling element and the frame, whereby the leveling element and frame overlap to a certain extent due to the corresponding guide.

[0039] Alternatively or preferably additionally, the module has a total height of 20 mm to 150 mm, preferably 40 mm to 100 mm.

[0040] Alternatively, or preferably additionally, the leveling element is height-adjustable. Preferably, the height of the leveling element is changed by sawing, cutting, and / or telescoping. Adjusting the height of the leveling element can be done directly on-site, particularly in the precast plant or on the construction site, allowing the leveling element to be adapted to the desired requirements. However, the adjustability of the leveling element within the module allows for a certain tolerance in the adjustment. This enables the leveling element to be adjusted easily and using simple tools, such as a saw, an angle grinder, or scissors.

[0041] In an advantageous embodiment of the module, at least one connecting element is arranged on the frame for a force-fit and / or form-fit connection of the module to the mounting element. The connecting element thus ensures a secure connection between the module and the mounting element. This prevents the module from shifting relative to the mounting element and improves the filling of the mounting element. In particular, the connecting element is designed as a latch or a clip, which allows the module to be easily connected to the mounting element.

[0042] Alternatively, or preferably additionally, the module is bonded to the mounting element by means of a material bond. For example, an adhesive bond can exist between the module and the mounting element.

[0043] As a further solution, an installation element for a precast element, in particular for a precast element made of concrete, is specified, wherein the installation element comprises a preferably elongated sleeve and a module for filling an installation element as described above, wherein the module is arranged at an opening in the outer surface of the sleeve, which opening preferably extends substantially in a plane perpendicular to the vertical axis of the module.

[0044] In an advantageous embodiment, the module is connected to the sleeve.

[0045] Alternatively, or preferably additionally, the module frame is integrally formed with the sleeve. This allows the sleeve of the installation element and the frame to form a single unit, thereby increasing the stability of the frame and thus of the entire installation element. In particular, the module frame is part of the sleeve.

[0046] In a further preferred embodiment, the installation element is designed to transmit forces between a first load-bearing building component, in particular a building wall, and a second load-bearing building component, in particular a stair section or a landing slab, wherein the installation element interacts with a support element that extends within the sleeve and is movably arranged relative to the sleeve. In a preferred embodiment, the installation element also includes the support element.

[0047] Preferably, the sleeve and optionally the module, in particular the entire installation element, can be filled, and in particular completely filled, with a curable material, especially a filler material. Preferably, the curable material is a mineral material, for example, a mortar or grout.

[0048] Another solution involves a precast concrete element with at least one embedded element as described above, as well as reinforcement, whereby the embedded element and the reinforcement are integrated into the concrete of the precast element. The precast element thus comprises all the essential elements for positioning, aligning, and connecting it on-site in relation to other precast elements or building components. Furthermore, manufacturing such precast elements is simpler than fabricating a similar element directly on-site, resulting in faster, simpler, and more cost-effective production.

[0049] After positioning the prefabricated element and the support element on the construction site, the only remaining step is to fill the installation element via the module accordingly, thereby fixing the prefabricated element to other parts of the building.

[0050] As a further solution, a method for producing a precast concrete element, in particular a precast element as set out above, is specified, wherein the method comprises the following steps: A) Providing at least one embedding element as described above, as well as formwork for the precast element, which formwork substantially corresponds to the later shape of the precast element; B) Arranging the embedding element and reinforcement in and / or on the formwork; C) Aligning the embedding element relative to a reference mark by applying force to the modulus of the embedding element; D) Pouring liquid concrete into the formwork and allowing the concrete to harden; and E) Removing the precast element from the formwork after hardening.

[0051] The module for filling the insert allows the insert to be easily aligned relative to a reference mark and thus to the precast element being manufactured, depending on the insert's position on or in the formwork and the reinforcement. The compensating element guided in and / or on the frame allows for flexible alignment of the insert. Specifically, the insert or the module for filling the insert is aligned so that an edge of the module or the insert itself is essentially flush with the surface of the precast element or is completely embedded within it.

[0052] In a preferred embodiment of the method, in process step B), the module for filling the insert is placed on or rests on the formwork, particularly on a formwork base. In this case, the precast element is manufactured using a reverse process, whereby the final surface of the precast element is formed on the formwork base. This manufacturing method allows for the appropriate alignment and positioning of the module by applying a force to it. Optionally, the module or insert can be further secured in the desired position, for example, to the reinforcement or the formwork itself.

[0053] In a further preferred embodiment, the finished component is manufactured in a standing production process.

[0054] Alternatively, or preferably additionally, in process step B), the module is arranged so that it is positioned on a side facing away from the formwork base. In this position, the module can also be aligned according to the reference mark for filling the insert element. For example, it can be aligned so that the end element of the module is flush with the surface of the resulting precast element. In this case, the reference mark corresponds to the height of the precast element. Preferably, even with this method of production, the compensating element can be fixed in the corresponding position to the frame of the module or to the reinforcement or formwork of the precast element.

[0055] In a further preferred embodiment, the height of the compensating element of the module of the installation element is adjusted before process step B). The compensating element has a height that is flexibly designed to accommodate a large number of precast elements. Thus, especially with precast elements of low height, it may be necessary to first adjust the compensating element to the requirements and the height of the precast element. However, this adjustment does not need to be exact, as is known from the prior art. Rather, the module for filling the installation element allows for a certain degree of flexibility and tolerance, so that the height of the compensating element only needs to be roughly adjusted to the expected height of the precast element. Adjustment and alignment of the compensating element can then be carried out directly during installation by the module.The adjustment of the leveling element is carried out directly on-site at the construction site or in the precast plant immediately during installation, with the height of the leveling element being adjusted primarily by sawing and / or cutting and / or grinding and / or telescoping. The appropriate method for adjusting the height can be selected depending on the material of the leveling element.

[0056] Alternatively, or preferably additionally, a module opening, particularly on the side facing the formwork, is closed with a sealing element and / or sealed against the environment before or during process step B). The installation element itself is thus sealed, preventing the ingress of concrete or foreign materials into the installation element, especially into the sleeve of the installation element, during the production of the precast element. Contamination within the installation element, particularly within the sleeve, can negatively affect the subsequent alignment of the precast element or could even render the precast element unusable.

[0057] A preferred embodiment of the method is characterized by the fact that the module is fixed to the formwork and / or that the insert is fixed to the formwork and / or the reinforcement. This fixing allows the insert or the module to be held in position until the concrete of the precast element has sufficiently hardened, thereby integrating both the insert and the module used to fill the insert into the precast element. Fixing is unnecessary, for example, if the module itself has means for securing the compensating element relative to the frame.

[0058] The method for manufacturing a prefabricated component is specifically designed for manufacturing the aforementioned prefabricated component and / or an advantageous embodiment thereof. The aforementioned prefabricated component can be manufactured, in particular, according to a method for manufacturing a prefabricated component as described above or a preferred embodiment thereof.

[0059] The aforementioned invention is explained and described in more detail with reference to the following figures. They show: Figure 1: A module for filling a built-in element; Figures 2a to 2: Different designs of the frame or the compensating element in a top view; Figure 3: A built-in element with a module for filling the built-in element in a perspective view; Figure 4: A built-in element with a module for filling the built-in element in a side view; and Figure 5: A detail view from Figure 4 .

[0060] In Figure 1Figure 1 shows a perspective view of a module 1 according to the invention. The module 1 comprises a substantially rectangular frame 2, which has four side surfaces 3 and four recesses 4 in the corners of the frame 2. The side surfaces 3 extend into a vertical axis 12. Furthermore, the frame 2 has a connecting element 6 in the form of a circumferential notch on one side surface which extends in a plane perpendicular to the vertical axis 12, whereby the frame 2 or the module 1 is positively connected to a sleeve 17 of a mounting element 16.

[0061] Within the frame 2, which essentially has a U-shaped profile, a substantially rectangular compensating element 8 is arranged and guided, the compensating element 8 being offset from the frame 2. The compensating element 8 engages in the U-shaped profile of the frame 2 and is movably guided within it. A finishing element 10 in the form of a circumferential cover is also arranged on the side of the compensating element 8 facing away from the frame 2.

[0062] The frame 2 and the compensating element 8 form a channel 14 within the module 1, through which the installation element 16, which is operatively connected to the module 1 for filling, can be filled with a material, in particular a mineral-based filler material. The channel 14 has a module opening 11 on the side facing away from the frame 2, through which the filler material is directed into the channel 14 and subsequently into the installation element 16.

[0063] Within the frame 2, deformation elements 7, each in the form of a spring, are arranged at the four corners within the recesses 4. The compensating element 8 is supported against the frame 2 by these springs. The deformation elements 7 are arranged within the frame 2, with a cover in the form of caps arranged on the recesses 4. These caps prevent the deformation element 7 from popping out of the frame 2 when force is applied to the compensating element 8. The deformation elements 7 provide a resilient mounting for the compensating element 8 relative to the frame 2, allowing the compensating element 8 to be positioned and aligned accordingly by force applied to the frame 2.Additionally, means for fixing, in particular locking elements and / or fixing elements, can be arranged on the frame 2 and / or on the compensating element 8, by means of which the compensating element 8 can be fixed in a certain position relative to the frame 2.

[0064] Both frame 2 and compensating element 8 are made of plastic, manufactured using injection molding. This allows for cost-effective and rapid production of frame 2 and compensating element 8.

[0065] Module 1 thus has several deformation elements 7, which are arranged section by section across the frame 2 of module 1. These multiple deformation elements 7 also allow the compensating element 8 to be tilted or inclined relative to the frame 2, so that module 1 can be aligned with its surroundings and with a reference mark. The height of the frame 2 and the springs as deformation elements 7 is chosen such that the deformation element 7 has a compression path, which is essentially along the vertical axis 12, of up to 4 cm. The overall height 15 of module 1 can therefore be varied by up to 4 cm by applying a corresponding force to the compensating element 8.It is also possible that the compensating element 8 is modular in design, which allows individual sections of the compensating element 8 to be positioned accordingly and thus the total height 15 of the module 1 to be adjusted section by section.

[0066] In the Figure 2a to 2e Various configurations of the frame 2 or the compensating element 8 are shown in a top view. Besides a rectangular shape of the frame 3 or the compensating element 8, as shown in Figure 2a As shown, the frame 2 or the compensating element 8 can also have an octagonal shape ( Fig. 2b ), a square shape ( Fig. 2c ), a round shape ( Fig. 2d ) or an oval shape ( Fig. 2e ). In particular, the frame 2 or the compensating element 8 can also be designed as a regular or irregular polygon.

[0067] In Figure 3 is shown an installation element 16 according to the invention, which, in addition to the in Figure 1The illustrated module 1 comprises a sleeve 17 and an aperture 18. The sleeve 17 extends elongated in the plane perpendicular to the vertical axis 12. An aperture opening 19 is formed in the aperture 18, through which a support element (not shown) is movably arranged. The sleeve 17 has a filling opening 20 in its outer surface, in a plane perpendicular to the vertical axis 12, onto which the module 1 is placed. The outer surface of the sleeve 17 is also textured in this illustration, which, when manufacturing a precast concrete element, results in better anchoring of the installation element 16 in the concrete of the precast element. However, it is also conceivable and possible to design the outer surface without any texture, in particular to make it smooth.

[0068] In Figure 4 is that in Figure 3The illustrated installation element 16 is shown in more detail in a side sectional view. Module 1 is anchored in the sleeve 17 of the installation element 16 via connecting elements 6 in the form of projections, thereby achieving a force-fit and form-fit connection between the sleeve 17 and Module 1. Module 1 is anchored at the filling opening 20, so that the channel 14 of Module 1 is aligned with the filling opening 20, allowing the interior of the sleeve 17 to be filled via the channel 14 and the filling opening 20. As further shown in Figure 3 and 4 The end element 10 is clearly attached to the compensating element 8 and may be connected to the compensating element 8 in some places by means of force and / or form locking.

[0069] Within frame 2 of module 1, recesses 4 are formed, each containing a spring-shaped deformation element 7. These spring-shaped deformation elements 7 allow the compensating element 8 to move relative to frame 2, enabling adjustment of its position. This facilitates the simple adaptation and alignment of the installation element 16 to the specific site conditions. The alignment of the installation element 16 is determined by a reference mark specified by the user. For example, a reference mark might specify that the overall height of the installation element must not exceed a certain value, or that the end element 10 of module 1 must be flush with the surface of a precast element.

[0070] In Figure 5 is the area around frame 2 of the in the Figure 3 and 4illustrated installation element 16, which is in Figure 4 The recess 4 in the frame 2 is encircled and shown in more detail below. The recess 4 in the frame 2 is dimensioned such that the deformation element 7, in the form of a spring, is guided by the wall of the frame 2 in the form of the side walls 3. This reduces any play of the spring as the deformation element 7 within the frame 2, thereby enabling precise alignment and positioning of the compensating element 8 relative to the frame 2. In particular, a malfunction, such as the deformation element 7 popping out of the frame 2, can be prevented by the corresponding guidance of the deformation element 7 by the wall of the frame 2.

[0071] The compensating element 8 is in direct contact with the deformation body 7 via pressure elements 9, ensuring uniform pressure on the deformation body 7 when the compensating element 8 is appropriately aligned. The pressure element 9 is designed in the form of a plate, thus achieving uniform pressure on the deformation body 7. Within the U-shaped profile of the frame 2, anchoring elements 5 are arranged on the side facing the compensating element 8. These anchoring elements, in conjunction with the pressure element 9, prevent the compensating element 8 from decoupling and separating from the frame 2. The compensating element 8 is thus held within the profile of the frame 2 by the anchoring elements 5. The anchoring elements 5 define a maximum overall height 15 of the module 1.

[0072] In addition to a spring as a deformation element 7, other forms of deformation elements 7 can also be arranged within the recesses 4 or within the frame 2, for example, in the form of expanding and / or pre-compressed materials such as foam. The stiffness or spring constant of the spring as a deformation element 7 also depends on the application of the respective installation element. In particular, the springs have a high spring constant, which means that positioning the compensating element 8 within the frame 2 of module 1 requires a certain force. At the same time, a high spring constant prevents the achieved and desired fixed position of the compensating element 8 within the frame 2 from being altered by simple and unintentional force.

[0073] To allow for maximum flexibility and broad application of Module 1, the leveling element 8 has a total height of 150 mm. To adjust the overall height of Module 1, the leveling element 8 can be modified and shortened accordingly. This is easily done by sawing to a specific dimension, and accuracy is of secondary importance due to the adjustability of the leveling element 8 within the frame 2. Thus, inaccuracies in determining the height of the leveling element 8, as well as unevenness during installation, can be easily and flexibly compensated for. Reference symbol list
